我正在尝试将位图缩放到屏幕大小并将其设置为墙纸，但我注意到在某些设备上（屏幕有点宽），壁纸的高度有点凌乱 . 有人可以帮助我以正确的方式缩放图像吗？
这是我的代码：
int widthPx = getWindowManager().getDefaultDisplay()
.getWidth();
int heightPx = getWindowManager().getDefaultDisplay()
.getHeight();
// bmp = Bitmap.createScaledBitmap(bmp, widthPx, heightPx,
// true);
BitmapDrawable drawable = (BitmapDrawable) background
.getDrawable();
Bitmap bitmap = drawable.getBitmap();
try {
WallpaperManager myWallpaperManager = WallpaperManager
.getInstance(getApplicationContext());
Bitmap resizedBitmap = Bitmap.createScaledBitmap(
bitmap,
myWallpaperManager.getDesiredMinimumWidth(),
myWallpaperManager.getDesiredMinimumHeight(),
true);
myWallpaperManager.setWallpaperOffsetSteps(1, 1);
myWallpaperManager.suggestDesiredDimensions(widthPx,
heightPx);
myWallpaperManager.setBitmap(resizedBitmap);
Toast.makeText(BackgroundPreview.this,
getString(R.string.wallpaper_set),
Toast.LENGTH_SHORT).show();
finish();
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(BackgroundPreview.this,
getString(R.string.error_setting_wallpaper),
Toast.LENGTH_SHORT).show();
}
