Android学习08-----Android中的基本控件（下）(6)_菜单：Menu和隐式抽屉组件：SlidingDrawer

 

一、菜单： Menu

1 、选项菜单，通过程序生成

main.xml 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/txt"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="按下Menu键出现选项菜单" />

</LinearLayout>
 

 

Menu01_Activity.java 

package com.iflytek.demo;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;

public class Menu01_Activity extends Activity {
	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		menu.add(Menu.NONE, Menu.FIRST + 1, 5, "删除").setIcon(
				android.R.drawable.ic_menu_delete);
		menu.add(Menu.NONE, Menu.FIRST + 2, 2, "保存").setIcon(
				android.R.drawable.ic_menu_save);
		menu.add(Menu.NONE, Menu.FIRST + 3, 6, "帮助").setIcon(
				android.R.drawable.ic_menu_help);
		menu.add(Menu.NONE, Menu.FIRST + 4, 1, "添加").setIcon(
				android.R.drawable.ic_menu_add);
		menu.add(Menu.NONE, Menu.FIRST + 5, 4, "详情").setIcon(
				android.R.drawable.ic_menu_info_details);
		menu.add(Menu.NONE, Menu.FIRST + 6, 7, "发送").setIcon(
				android.R.drawable.ic_menu_send);
		menu.add(Menu.NONE, Menu.FIRST + 7, 3, "编辑").setIcon(
				android.R.drawable.ic_menu_edit);
		return true;
	}

	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		switch (item.getItemId()) { // 判断操作的菜单ID
		case Menu.FIRST + 1:
			Toast.makeText(this, "您选择的是“删除菜单”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 2:
			Toast.makeText(this, "您选择的是“保存菜单”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 3:
			Toast.makeText(this, "您选择的是“帮助菜单”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 4:
			Toast.makeText(this, "您选择的是“添加菜单”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 5:
			Toast.makeText(this, "您选择的是“详情菜单”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 6:
			Toast.makeText(this, "您选择的是“发送菜单”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 7:
			Toast.makeText(this, "您选择的是“编辑菜单”项", Toast.LENGTH_LONG).show();
			break;
		}
		return false;
	}

	@Override
	public void onOptionsMenuClosed(Menu menu) {
		Toast.makeText(this, "选项菜单关闭了", Toast.LENGTH_LONG).show();
	}

	@Override
	public boolean onPrepareOptionsMenu(Menu menu) {
		Toast.makeText(this,
				"在菜单显示（onCreateOptionsMenu()方法之前会调用此操作，可以在此操作之中完成一些预处理功能。）",
				Toast.LENGTH_LONG).show();
		return true;
	}

}
 

 

2 、通过配置文件生成菜单

Menu02_Activity.java 

package com.iflytek.demo;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;

public class Menu02_Activity extends Activity {
	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		super.getMenuInflater().inflate(R.menu.mymenu, menu);
		return true;
	}

	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		switch (item.getItemId()) { // 判断操作的菜单ID
		case Menu.FIRST + 1:
			Toast.makeText(this, "您选择的是“删除菜单”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 2:
			Toast.makeText(this, "您选择的是“保存菜单”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 3:
			Toast.makeText(this, "您选择的是“帮助菜单”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 4:
			Toast.makeText(this, "您选择的是“添加菜单”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 5:
			Toast.makeText(this, "您选择的是“详情菜单”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 6:
			Toast.makeText(this, "您选择的是“发送菜单”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 7:
			Toast.makeText(this, "您选择的是“编辑菜单”项", Toast.LENGTH_LONG).show();
			break;
		}
		return false;
	}

	@Override
	public void onOptionsMenuClosed(Menu menu) {
		Toast.makeText(this, "选项菜单关闭了", Toast.LENGTH_LONG).show();
	}

	@Override
	public boolean onPrepareOptionsMenu(Menu menu) {
		Toast.makeText(this,
				"在菜单显示（onCreateOptionsMenu()方法之前会调用此操作，可以在此操作之中完成一些预处理功能。）",
				Toast.LENGTH_LONG).show();
		return true;
	}
}
 

 

Res/menu/ mymenu.xml 

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
	<item android:id="@+id/item01" android:title="添加"
		android:icon="@android:drawable/ic_menu_add" />
	<item android:id="@+id/item02" android:title="保存"
		android:icon="@android:drawable/ic_menu_save" />
	<item android:id="@+id/item03" android:title="编辑"
		android:icon="@android:drawable/ic_menu_edit" />
	<item android:id="@+id/item04" android:title="详情"
		android:icon="@android:drawable/ic_menu_info_details" />
	<item android:id="@+id/item05" android:title="删除"
		android:icon="@android:drawable/ic_menu_delete" />
	<item android:id="@+id/item06" android:title="发送"
		android:icon="@android:drawable/ic_menu_send" />
	<item android:id="@+id/item07" android:title="帮助"
		android:icon="@android:drawable/ic_menu_help" />
</menu>
 

 

3 、程序实现上下文菜单

Menu03_Activity.java 

package com.iflytek.demo;

import android.app.Activity;
import android.os.Bundle;
import android.view.ContextMenu;
import android.view.ContextMenu.ContextMenuInfo;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class Menu03_Activity extends Activity {
	private String data[] = new String[] { "hello", "www.iteye.com", "Android" }; // 定义ListView的显示项
	private ListView listView = null;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		this.listView = new ListView(this);
		this.listView.setAdapter(new ArrayAdapter<String>(this,
				android.R.layout.simple_expandable_list_item_1, this.data));
		super.setContentView(this.listView);
		super.registerForContextMenu(this.listView);
	}

	@Override
	public boolean onContextItemSelected(MenuItem item) {
		switch (item.getItemId()) {
		case Menu.FIRST + 1:
			Toast.makeText(this, "您选择的是“添加联系人”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 2:
			Toast.makeText(this, "您选择的是“查看详情”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 3:
			Toast.makeText(this, "您选择的是“删除信息”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 4:
			Toast.makeText(this, "您选择的是“另存为”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 5:
			Toast.makeText(this, "您选择的是“编辑”项", Toast.LENGTH_LONG).show();
			break;
		}
		return false;
	}

	@Override
	public void onContextMenuClosed(Menu menu) {
		Toast.makeText(this, "上下文菜单关闭了", Toast.LENGTH_LONG).show();
	}

	@Override
	public void onCreateContextMenu(ContextMenu menu, View v,
			ContextMenuInfo menuInfo) {
		super.onCreateContextMenu(menu, v, menuInfo);
		menu.setHeaderTitle("信息操作");
		menu.add(Menu.NONE, Menu.FIRST + 1, 1, "添加联系人");
		menu.add(Menu.NONE, Menu.FIRST + 2, 2, "查看详情");
		menu.add(Menu.NONE, Menu.FIRST + 3, 3, "删除信息");
		menu.add(Menu.NONE, Menu.FIRST + 4, 4, "另存为");
		menu.add(Menu.NONE, Menu.FIRST + 5, 5, "编辑");
	}
}
 

 

4 、配置实现上下文菜单

Menu04_Activity.java 

package com.iflytek.demo;

import android.app.Activity;
import android.os.Bundle;
import android.view.ContextMenu;
import android.view.ContextMenu.ContextMenuInfo;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class Menu04_Activity extends Activity {
	private String data[] = new String[] { "hello", "www.iteye.com", "Android" }; // 定义ListView的显示项
	private ListView listView = null;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		this.listView = new ListView(this);
		this.listView.setAdapter(new ArrayAdapter<String>(this,
				android.R.layout.simple_expandable_list_item_1, this.data));
		super.setContentView(this.listView);
		super.registerForContextMenu(this.listView);
	}

	@Override
	public boolean onContextItemSelected(MenuItem item) {
		switch (item.getItemId()) {
		case Menu.FIRST + 1:
			Toast.makeText(this, "您选择的是“添加联系人”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 2:
			Toast.makeText(this, "您选择的是“查看详情”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 3:
			Toast.makeText(this, "您选择的是“删除信息”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 4:
			Toast.makeText(this, "您选择的是“另存为”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 5:
			Toast.makeText(this, "您选择的是“编辑”项", Toast.LENGTH_LONG).show();
			break;
		}
		return false;
	}

	@Override
	public void onContextMenuClosed(Menu menu) {
		Toast.makeText(this, "上下文菜单关闭了", Toast.LENGTH_LONG).show();
	}

	@Override
	public void onCreateContextMenu(ContextMenu menu, View v,
			ContextMenuInfo menuInfo) {
		super.onCreateContextMenu(menu, v, menuInfo);
		menu.setHeaderTitle("信息操作");
		super.getMenuInflater().inflate(R.menu.mymenu, menu);
	}
}

 

Res/ menu/ mymenu 

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
	<item android:id="@+id/item01" android:title="添加联系人" />
	<item android:id="@+id/item02" android:title="查看详情" />
	<item android:id="@+id/item03" android:title="删除信息" />
	<item android:id="@+id/item04" android:title="另存为" />
	<item android:id="@+id/item05" android:title="编辑" />
</menu>

 

5 、子菜单基本实现

Menu05_Activity.java 

package com.iflytek.demo;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.SubMenu;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class Menu05_Activity extends Activity {
	private String data[] = new String[] { "hello", "www.iteye.com", "Android" }; // 定义ListView的显示项
	private ListView listView = null;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		this.listView = new ListView(this);
		this.listView.setAdapter(new ArrayAdapter<String>(this,
				android.R.layout.simple_expandable_list_item_1, this.data));
		super.setContentView(this.listView);
		super.registerForContextMenu(this.listView);
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		SubMenu fileMenu = menu.addSubMenu("文件");
		SubMenu editMenu = menu.addSubMenu("编辑");
		fileMenu.add(Menu.NONE, Menu.FIRST + 1, 1, "新建");
		fileMenu.add(Menu.NONE, Menu.FIRST + 2, 2, "打开");
		fileMenu.add(Menu.NONE, Menu.FIRST + 3, 3, "保存");
		editMenu.add(Menu.NONE, Menu.FIRST + 4, 4, "撤消");
		editMenu.add(Menu.NONE, Menu.FIRST + 5, 5, "恢复");
		return true;
	}

	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		switch (item.getItemId()) { // 判断操作的菜单ID
		case Menu.FIRST + 1:
			Toast.makeText(this, "您选择的是“添加联系人”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 2:
			Toast.makeText(this, "您选择的是“查看详情”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 3:
			Toast.makeText(this, "您选择的是“删除信息”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 4:
			Toast.makeText(this, "您选择的是“另存为”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 5:
			Toast.makeText(this, "您选择的是“编辑”项", Toast.LENGTH_LONG).show();
			break;
		}
		return false;
	}

}

 

6 、通过配置实现子菜单

Res/menu/ editmenu.xml 

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
	<item android:id="@+id/item04" android:title="撤消" />
	<item android:id="@+id/item05" android:title="恢复" />
</menu>

 

filemenu.xml 

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
	<item android:id="@+id/item01" android:title="新建" />
	<item android:id="@+id/item02" android:title="打开" />
	<item android:id="@+id/item03" android:title="保存" />
</menu>

 

Menu06_Activity.java 

package com.iflytek.demo;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.SubMenu;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class Menu06_Activity extends Activity {
	private String data[] = new String[] { "hello", "www.iteye.com", "Android" }; // 定义ListView的显示项
	private ListView listView = null;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		this.listView = new ListView(this);
		this.listView.setAdapter(new ArrayAdapter<String>(this,
				android.R.layout.simple_expandable_list_item_1, this.data));
		super.setContentView(this.listView);
		super.registerForContextMenu(this.listView);
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		SubMenu fileMenu = menu.addSubMenu("文件");
		SubMenu editMenu = menu.addSubMenu("编辑");
		super.getMenuInflater().inflate(R.menu.filemenu, fileMenu);
		super.getMenuInflater().inflate(R.menu.editmenu, editMenu);
		return true;
	}

	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		switch (item.getItemId()) { // 判断操作的菜单ID
		case Menu.FIRST + 1:
			Toast.makeText(this, "您选择的是“添加联系人”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 2:
			Toast.makeText(this, "您选择的是“查看详情”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 3:
			Toast.makeText(this, "您选择的是“删除信息”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 4:
			Toast.makeText(this, "您选择的是“另存为”项", Toast.LENGTH_LONG).show();
			break;
		case Menu.FIRST + 5:
			Toast.makeText(this, "您选择的是“编辑”项", Toast.LENGTH_LONG).show();
			break;
		}
		return false;
	}

}

 

二、隐式抽屉组件： SlidingDrawer

SlidingDrawerActivity.java 

package com.iflytek.demo;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.SlidingDrawer;
import android.widget.SlidingDrawer.OnDrawerCloseListener;
import android.widget.SlidingDrawer.OnDrawerOpenListener;
import android.widget.SlidingDrawer.OnDrawerScrollListener;
import android.widget.Toast;

public class SlidingDrawerActivity extends Activity {
	private String data[] = new String[] { "hello", "www.iteye.com", "Android" }; // 定义ListView的显示项
	private ListView listView = null;
	private SlidingDrawer slidingDrawer = null;
	private ImageView handle = null;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		LinearLayout layout = (LinearLayout) super.findViewById(R.id.content); // 向里面保存ListView
		this.listView = new ListView(this);
		this.listView.setAdapter(new ArrayAdapter<String>(this,
				android.R.layout.simple_expandable_list_item_1, this.data));
		layout.addView(this.listView);

		this.slidingDrawer = (SlidingDrawer) super
				.findViewById(R.id.slidingdrawer);
		this.handle = (ImageView) super.findViewById(R.id.handle);

		this.slidingDrawer
				.setOnDrawerOpenListener(new OnDrawerOpenListenerImpl());
		this.slidingDrawer
				.setOnDrawerCloseListener(new OnDrawerCloseListenerImpl());
		this.slidingDrawer
				.setOnDrawerScrollListener(new OnDrawerScrollListenerImpl());
	}

	private class OnDrawerOpenListenerImpl implements OnDrawerOpenListener {

		@Override
		public void onDrawerOpened() {
			SlidingDrawerActivity.this.handle
					.setImageResource(R.drawable.ico_right);
		}

	}

	private class OnDrawerCloseListenerImpl implements OnDrawerCloseListener {

		@Override
		public void onDrawerClosed() {
			SlidingDrawerActivity.this.handle
					.setImageResource(R.drawable.ico_left);
		}

	}

	private class OnDrawerScrollListenerImpl implements OnDrawerScrollListener {

		@Override
		public void onScrollEnded() {
			Toast.makeText(SlidingDrawerActivity.this, "窗口拖动结束。",
					Toast.LENGTH_SHORT).show();
		}

		@Override
		public void onScrollStarted() {
			Toast.makeText(SlidingDrawerActivity.this, "正在拖动窗口。",
					Toast.LENGTH_SHORT).show();
		}

	}
}

 

main.xml 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <SlidingDrawer
        android:id="@+id/slidingdrawer"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:content="@+id/content"
        android:handle="@+id/handle"
        android:orientation="horizontal" >

        <ImageView
            android:id="@+id/handle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ico_left" />

        <LinearLayout
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/content"

            android:layout_height="fill_parent"
            android:orientation="vertical" >
        </LinearLayout>
    </SlidingDrawer>

</LinearLayout>
