Android中的Button、ImageButton自定义点击效果

1.在代码里面。

imageButton.setOnTouchListener(new OnTouchListener(){   
                        @Override  
                        public boolean onTouch(View v, MotionEvent event) {   
                                if(event.getAction() == MotionEvent.ACTION_DOWN){   
                                        //更改为按下时的背景图片   
                                        v.setBackgroundResource(R.drawable.pressed);   
                                }else if(event.getAction() == MotionEvent.ACTION_UP){   
                                        //改为抬起时的图片   
                                        v.setBackgroundResource(R.drawable.released);   
                                }   
                                return false;   
                        }   
                });  

<?xml version="1.0" encoding="UTF-8"?>  
<selector xmlns:android="http://schemas.android.com/apk/res/android">  
    <item           android:state_pressed="false"  android:drawable="@drawable/button_add" />  
    <item           android:state_pressed="true"   android:drawable="@drawable/button_add_pressed" />  
    <item           android:state_focused="true"    android:drawable="@drawable/button_add_pressed" />  
<item           android:drawable="@drawable/button_add" />  
</selector>  

这个文件放在drawable目录下面。命名为button_add_x.xml
使用的时候

<ImageButton  
                        android:id="@+id/ImageButton"  
                        android:layout_width="wrap_content"  
                        android:layout_height="wrap_content"  
                        android:background="#00000000"  
                        android:src="@drawable/button_add_x" >  
</ImageButton>  

/**  
   * 按下这个按钮进行的颜色过滤  
   */  
  public final static float[] BT_SELECTED=new float[] {    
      2, 0, 0, 0, 2,    
      0, 2, 0, 0, 2,    
      0, 0, 2, 0, 2,    
      0, 0, 0, 1, 0 };   
     
  /**  
   * 按钮恢复原状的颜色过滤  
   */  
  public final static float[] BT_NOT_SELECTED=new float[] {    
      1, 0, 0, 0, 0,    
      0, 1, 0, 0, 0,    
      0, 0, 1, 0, 0,    
      0, 0, 0, 1, 0 };   
     
  /**  
   * 按钮焦点改变  
   */  
  public final static OnFocusChangeListener buttonOnFocusChangeListener=new OnFocusChangeListener() {   
     
  @Override  
  public void onFocusChange(View v, boolean hasFocus) {   
   if (hasFocus) {   
    v.getBackground().setColorFilter(new ColorMatrixColorFilter(BT_SELECTED));   
    v.setBackgroundDrawable(v.getBackground());   
   }   
   else  
   {   
    v.getBackground().setColorFilter(new ColorMatrixColorFilter(BT_NOT_SELECTED));   
     v.setBackgroundDrawable(v.getBackground());   
   }   
  }   
 };   
    
  /**  
   * 按钮触碰按下效果  
   */  
 public final static OnTouchListener buttonOnTouchListener=new OnTouchListener() {   
  @Override  
  public boolean onTouch(View v, MotionEvent event) {   
   if(event.getAction() == MotionEvent.ACTION_DOWN){   
    v.getBackground().setColorFilter(new ColorMatrixColorFilter(BT_SELECTED));   
    v.setBackgroundDrawable(v.getBackground());   
    }   
    else if(event.getAction() == MotionEvent.ACTION_UP){   
     v.getBackground().setColorFilter(new ColorMatrixColorFilter(BT_NOT_SELECTED));   
     v.setBackgroundDrawable(v.getBackground());   
    }   
   return false;   
  }   
 };   
    
 /**  
  * 设置图片按钮获取焦点改变状态  
  * @param inImageButton  
  */  
 public final static void setButtonFocusChanged(View inView)   
 {   
  inView.setOnTouchListener(buttonOnTouchListener);   
  inView.setOnFocusChangeListener(buttonOnFocusChangeListener);   
 }  

代码可以适当修改实现3个不同的状态：正常，获取焦点，点击。
