1.放在drawable下的selector.xml文件
代码如下:
android="http://schemas.android.com/apk/res/Android"
android:drawable="@drawable/temp2" /
2.布局文件main.xml
代码如下:
http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/
android:drawableTop="@drawable/shouru"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/button"
android:background="@drawable/selector"/
方法二
1.布局文件main.xml
[code]
http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/
android:id="@+id/button"
android:drawableTop="@drawable/shouru"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/button"
android:background="@drawable/temp4"/
2.主要的java代码,实现点击效果:
代码如下:
Button button = (Button) this.findViewById(R.id.button);
button.setOnTouchListener(new Button.OnTouchListener(){
@Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN){
v.setBackgroundResource(R.drawable.temp1);
Log.i("TestAndroid Button", "MotionEvent.ACTION_DOWN");
}
else if(event.getAction() == MotionEvent.ACTION_UP){
v.setBackgroundResource(R.drawable.temp2);
Log.i("TestAndroid Button", "MotionEvent.ACTION_UP");
}
return false;
}
});
