This article will share with you an example code to introduce the example code that can be dimmed by ImageView. It is very good and has reference value. If you need it, please refer to it.

I won’t say much nonsense, I will just post the code to you. The specific code is as follows:

import ;
import ;
import ;
import ;
import ;
import ;
public class MyImageView extends ImageView{
  public MyImageView(Context context, AttributeSet attrs) {
    super(context, attrs);
    // TODO Auto-generated constructor stub
    (VIEW_TOUCH_DARK);
  }
  public static final OnTouchListener VIEW_TOUCH_DARK = new OnTouchListener() { 
    //Dark (three -50, the larger the value, the deeper the effect)    public final float[] BT_SELECTED_DARK = new float[] { 1, 0, 0, 0, -50, 0, 1, 
        0, 0, -50, 0, 0, 1, 0, -50, 0, 0, 0, 1, 0 };
    /*
     //Brighten
     public final float[] BT_SELECTED_LIGHT = new float[] { 1, 0, 0, 0, 50, 0, 1,
         0, 0, 50, 0, 0, 0, 1, 0, 50, 0, 0, 0, 1, 0 };
     //recover
     public final float[] BT_NOT_SELECTED = new float[] { 1, 0, 0, 0, 0, 0,
         1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 1, 0 };
      */
    @Override 
    public boolean onTouch(View v, MotionEvent event) { 
      if (() == MotionEvent.ACTION_DOWN) {
        ImageView iv = (ImageView) v; 
        (new ColorMatrixColorFilter(BT_SELECTED_DARK));
      } else if (() == MotionEvent.ACTION_UP) {
        ImageView iv = (ImageView) v; 
        ();
      } 
      return false; //If false, no further execution will be performed after executing ACTION_DOWN    } 
  }; 
}

The above is the example code (android code skills) that the editor introduces to you. I hope it will be helpful to you. If you have any questions, please leave me a message and the editor will reply to you in time. Thank you very much for your support for my website!
