Android ImageButton | Button | TextView 点击和触摸效果

ImageButton------------------------------------------------>

一、Java  代码:

在drawable目录下添加新的xml文件

 button_add_x.xmlimageButton.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;
  } });

二、1)在drawable目录下添加新的xml文件 button_add_x.xml

    <?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>    

2)在布局文件中写

<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> 

Button------------------------------------------------>

Java代码:

    mBtn = (Button) findViewById(R.id.btn); //btn为layout中的Button ID    
    mBtn.setOnTouchListener(new OnTouchListener() {    
    public boolean onTouch(View arg0,MotionEvent arg1) {    
    if(arg1.getAction() == MotionEvent.ACTION_DOWN) {    
    arg0.setBackgroundResource(R.drawable.pressed); //按下的图片对应pressed    
    } else if(arg1.getAction() == MotionEvent.ACTION_UP) {    
    arg0.setBackgroundResource(R.drawable.normal); //常态下的图片对应normal    
    }    
    else if() //这里还可以继续实现MotionEvent.ACTION_MOVE和MotionEvent.ACTION_CANCEL等实现更多的特效    
    return false;    
    }    
    });   

TextView------------------------------------------------>

 改变字体颜色:和Button的区别是改变的是textColor属性,而且selector文件定义在color     - ->
       1.在layout文件中指定TextView的textColor属性,如android:textColor="@color/textview_color";
       2.在color目录下添加新的xml文件textview_color.xml并指定TextView在各种状态下的色值

    <?xml version="1.0" encoding="utf-8"?>     
    <selector xmlns:android="http://schemas.android.com/apk/res/android">     
      <item android:state_selected="true" android:color="#FFF" />     
      <item android:state_focused="true" android:color="#FFF" />     
      <item android:state_pressed="true" android:color="#FFF" />     
      <item android:color="#000" />     
    </selector>
