复制代码代码如下:
Resources res=getResources();
BitmapDrawable bmpDraw=(BitmapDrawable)res.getDrawable(R.drawable.icon);
Bitmap bmp=bmpDraw.getBitmap();
try{
setWallpaper(bmp);
}catch(IOException e) {
e.printStackTrace();
}
2.在manifest中增加设置桌面的权限
<uses-permission android:name="android.permission.SET_WALLPAPER" />
