先看效果:
一个线程30行代码搞定:
代码语言:javascript复制public class MainActivity extends Activity {
Thread thread = new Thread(){
@Override
public void run() {
for (;current<5;){
if (current >= 3) {
current = 0;
}
//使用资源文件 当然你也可以使用其他图片bitmap
BitmapDrawable bitmap = (BitmapDrawable) getResources().getDrawable(wallpapers[current ]);
wallpaperManager = WallpaperManager.getInstance(MainActivity.this);
try {
wallpaperManager.setBitmap(bitmap.getBitmap());
} catch (IOException e) {
e.printStackTrace();
}
}
}
};
int[] wallpapers = new int[]{
R.drawable.background1, R.drawable.background2, R.drawable.background3
};
WallpaperManager wallpaperManager;
int current = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
thread.start();
}
}
就这么简单 对了别忘了在mainfest里加权限
代码语言:javascript复制<!--授予用户修改壁纸权限-->
<uses-permission android:name="android.permission.SET_WALLPAPER" />
