Android顶用GridView实现九宫格的两种方法

Android中用GridView实现九宫格的两种方法

1.传统办法：实现一个继承BaseAdapter的 ImageAdapter

java代码如下：

package com.test;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;

public class GridViewActivity extends Activity {

	//存放各功能图片
	private Integer[] mFunctionPics = {R.drawable.mobilesecurity,R.drawable.infosecurity,
			R.drawable.no_interrupt,R.drawable.bianjiejieting,R.drawable.xiaomishu
			,R.drawable.sms_send_attime,R.drawable.yule,R.drawable.setting};
	//存放各功能的名称
	private Integer[] mFunctionName = {R.string.phone_tools_box_name1,
			R.string.phone_tools_box_name2,R.string.phone_tools_box_name3,
			R.string.phone_tools_box_name4,R.string.phone_tools_box_name5,
			R.string.phone_tools_box_name6,R.string.phone_tools_box_name7,
			R.string.phone_tools_box_name8};
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.gridview_main);
		
		GridView girdview = (GridView) this.findViewById(R.id.girdview);
		girdview.setAdapter(new ImageAdapter(this));
		girdview.setOnItemClickListener(new OnItemClickListener() {
			@Override
			public void onItemClick(AdapterView<?> parent, View view,
					int position, long id) {
				Toast.makeText(GridViewActivity.this, "图片ID："+mFunctionPics[position],1).show();
			}
		});
		
	}
	
	public class ImageAdapter extends BaseAdapter{

		private Context mContext;
		private LayoutInflater inflater;
		private class GirdTemp{
			ImageView phone_function_pic;
			TextView phone_function_name;
		}
		public ImageAdapter(Context c){
			mContext = c;
			inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
		}
		@Override
		public int getCount() {
			return mFunctionPics.length;
		}

		@Override
		public Object getItem(int position) {
			return position;
		}

		@Override
		public long getItemId(int position) {
			return position;
		}

		@Override
		public View getView(int position, View convertView, ViewGroup parent) {
			GirdTemp temp;
			if(convertView == null){
				convertView = inflater.inflate(R.layout.gridview_item, null);
				temp = new GirdTemp();
				temp.phone_function_pic = (ImageView) convertView.findViewById(R.id.function_view);
				temp.phone_function_name = (TextView) convertView.findViewById(R.id.function_name);
				convertView.setTag(holder);
			}else{
				temp = (GirdHolder) convertView.getTag();
			}
			temp.phone_function_pic.setImageResource(mFunctionPics[position]);
			temp.phone_function_name.setText(mFunctionName[position]);
			return convertView;
		}
		
	}

}

girdview_main.xml代码如下：

<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/gridview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:numColumns="auto_fit" //自动适应多少行
android:verticalSpacing="20dp" //两行之间的距离
android:horizontalSpacing="20dp" //两列之间的距离
android:gravity="center"
/>

girdview_item.xml源码：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
<ImageView>
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/function_view"
android:layout_centerHorizontal="true"
</ImageView>
<TextView
android:layout_width="wrap_content"
android:layout_below="@+id/function_view"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:id="@+id/function_name">
</TextView>
</RelativeLayout>

2.跟ListView类似的数据绑定方式
