Programmatically set android phone's background
提问by Phate
I'd like to allow the user to choose a background from a list of images, the user clicks on one of them and that image is used as background for his phone. My app should simply be another version of the android default gallery.
我想允许用户从图像列表中选择一个背景，用户点击其中一个，该图像用作他手机的背景。我的应用程序应该只是 android 默认库的另一个版本。

First one, you need to set the permission in your Manifest.xmlfile
第一个，您需要在Manifest.xml文件中设置权限
<uses-permission android:name="android.permission.SET_WALLPAPER"/>
And you can set the background with this:
你可以用这个设置背景：
Button buttonSetWallpaper = (Button)findViewById(R.id.set);
ImageView imagePreview = (ImageView)findViewById(R.id.preview);
imagePreview.setImageResource(R.drawable.five);
buttonSetWallpaper.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
WallpaperManager myWallpaperManager
= WallpaperManager.getInstance(getApplicationContext());
try {
myWallpaperManager.setResource(R.drawable.five);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}});

You can set a wallpaper using the WallpaperManager class. For example:
您可以使用WallpaperManager 类设置墙纸。例如：
WallpaperManager wallpaperManager =
WallpaperManager.getInstance(getApplicationContext());
wallpaperManager.setBitmap(someBitmap);
