实现方式有两种:
一、代码中实现:
imgbtnSetup.setOnTouchListener( new View.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.btn_setup_hover); }else if(event.getAction() == MotionEvent.ACTION_UP){ //改为抬起时的图片 v.setBackgroundResource(R.drawable.btn_setup); } return false; } });
?
二、xml布局实现:
<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:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/button_add_x" />
