BitmapDrawable flip(BitmapDrawable d)
{
  Matrix m = new Matrix();
  m.preScale(-1, 1);
  Bitmap src = d.getBitmap();
  Bitmap dst = Bitmap.createBitmap(src, 0, 0, src.getWidth(), src.getHeight(), m, false);
  dst.setDensity(DisplayMetrics.DENSITY_DEFAULT);
  return new BitmapDrawable(dst);
}

代码示例来源：origin: gzu-liyujiang/AndroidPicker

public static Bitmap toBitmap(byte[] bytes, int width, int height) {
  Bitmap bitmap = null;
  if (bytes.length != 0) {
    try {
      BitmapFactory.Options options = new BitmapFactory.Options();
      // 不进行图片抖动处理
      options.inDither = false;
      // 设置让解码器以最佳方式解码
      options.inPreferredConfig = null;
      if (width > 0 && height > 0) {
        options.outWidth = width;
        options.outHeight = height;
      }
      bitmap = BitmapFactory.decodeByteArray(bytes, 0, bytes.length, options);
      bitmap.setDensity(96);// 96 dpi
    } catch (Exception e) {
      LogUtils.error(e);
    }
  }
  return bitmap;
}

@Test

}

downsampled.setDensity(displayMetrics.densityDpi);

代码示例来源：origin: Bilibili/DanmakuFlameMaster

if (density > 0) {
  mDensity = density;
  bitmap.setDensity(density);

代码示例来源：origin: stackoverflow.com

RelativeLayout rl = (RelativeLayout) findViewById(R.id.rl1);

final Options bitmapOptions=new Options();
DisplayMetrics matrix = getResources().getDisplayMetrics();
bitmapOptions.inDensity = matrix.densityDpi;
bitmapOptions.inTargetDensity=1;

/*`final` modifier might be necessary for the Bitmap*/
Bitmap bmp= BitmapFactory.decodeResource(getResources(), R.drawable.ver_bottom_panel_tiled_long, bitmapOptions);
bmp.setDensity(Bitmap.DENSITY_NONE);
bmp = Bitmap.createBitmap(bmp, 0, 0, rl.getWidth(), bmp.getHeight());

代码示例来源：origin: stackoverflow.com

Bitmap myBitmap = ... 
   // S3 and S4 get confused about displaying bitmaps without a specific density,
   // and fail to scale them properly. Setting the density to this value helps (is possible ANY density helps, but haven't tested this)
   myBitmap.setDensity(DisplayMetrics.DENSITY_HIGH);
   myImageView.setImageBitmap(myBitmap);
