如何通过Android中的URL设置导航抽屉的用户头像?

问题描述：

这是我的header.xml

This is my header.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="@dimen/nav_header_height"
    android:background="@drawable/side_nav_bar"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:theme="@style/ThemeOverlay.AppCompat.Dark" android:orientation="vertical"
    android:gravity="bottom">

    <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content"
        android:paddingTop="@dimen/nav_header_vertical_spacing"
        android:src="@android:drawable/sym_def_app_icon" android:id="@+id/imageView" />

    <TextView android:layout_width="match_parent" android:layout_height="wrap_content"
        android:paddingTop="@dimen/nav_header_vertical_spacing" android:text="Android Studio"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1" />

    <TextView android:layout_width="wrap_content" android:layout_height="wrap_content"
        android:text="android.studio@android.com" android:id="@+id/textView" />

</LinearLayout>

这是我的oncreate方法，我正在使用导航视图

This is my oncreate method, i am using Navigation view

  @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.setDrawerListener(toggle);
        toggle.syncState();

        ImageLoader.getInstance().init(ImageLoaderConfiguration.createDefault(MainActivity.this));
        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        navigationView.setNavigationItemSelectedListener(this);
        ImageView imageView = (ImageView) navigationView.getHeaderView(0).findViewById(R.id.imageView);
        ImageLoader.getInstance().displayImage("https://www.google.co.in/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png", imageView);
    }

我尝试过这个，但是图像根本没有改变吗?什么都没发生，我已经包含了UniversalImageloader.jar，并且也添加了所有依赖项.可能是什么问题?

I tried this, but the image is not changing at all? Nothings happening,i have included universalimageloader.jar, and added all dependencies too. what can be the issue?

答

我假定您使用Android Design Support Library中的NavigationView，如链接中所示:

I assume that you use NavigationView from Android Design Support Library as in the link: Android blogspot

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

<!-- your content layout -->

<android.support.design.widget.NavigationView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        app:headerLayout="@layout/drawer_header"
        app:menu="@menu/drawer"/>
</android.support.v4.widget.DrawerLayout>

drawer_header.xml为:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="match_parent"
          android:layout_height="100dp"
          android:gravity="bottom"
          android:orientation="vertical"
          android:theme="@style/ThemeOverlay.AppCompat.Dark">
<ImageView
    android:id="@+id/ivHeader"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>
</LinearLayout>

这是我使用UniversalImageLoader在标头中为ImageView加载图像的方式:

This is how I load image for ImageView in header using UniversalImageLoader:

initImageLoader(this);
NavigationView navigationView = (NavigationView) findViewById(R.id.navigation);
ImageView imageView = (ImageView) navigationView.getHeaderView(0).findViewById(R.id.ivHeader);
ImageLoader.getInstance().displayImage("YourImageUrl", imageView);

请注意，从版本compile 'com.android.support:design:23.1.1'开始，可以使用navigationView.getHeaderView(0)找到HeaderView.希望对您有所帮助.

Note that from version compile 'com.android.support:design:23.1.1', HeaderView can be find by using navigationView.getHeaderView(0). Hope it helps.
