Frage

I´ve got an Android app that I developed, but my challenge is that once I´ve got the picture, I need to be able to change the picture effect, for example, gris to sepia effect.

Using this method you should be able to acheive your goal.

public static void SepiaEffect(Drawable drawable) {


if (drawable == null)

return;



final ColorMatrix matrixA = new ColorMatrix();
  // making image B&W
  matrixA.setSaturation(0);

  final ColorMatrix matrixB = new ColorMatrix();
  // applying scales for RGB color values
  matrixB.setScale(1f, .95f, .82f, 1.0f);
  matrixA.setConcat(matrixB, matrixA);

  final ColorMatrixColorFilter filter = new ColorMatrixColorFilter(matrixA);
  drawable.setColorFilter(filter);
}
