适用于Android的库，设置为适合屏幕的壁纸

Question

有没有我可以在android中用于壁纸的库。我希望我的位图设置为壁纸并适合其屏幕设备

DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int height = displaymetrics.heightPixels;
int width = displaymetrics.widthPixels;

Bitmap yourbitmap = Bitmap.createScaledBitmap(bmp, width, height, true);
WallpaperManager wallpaperManager = WallpaperManager.getInstance(this);

try {
    wallpaperManager.setBitmap(yourbitmap);
} catch (IOException e) {
     e.printStackTrace();
}
