android Button Theme 自定义小技巧

方法一

1.放在drawable下的selector.xml文件

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="@drawable/temp1" />
<item android:state_pressed="false" android:state_focused="false"
android:drawable="@drawable/temp2" />
<item android:state_focused="true" android:drawable="@drawable/temp3" />
<item android:state_focused="false" android:drawable="@drawable/temp4" />
</selector>

2.布局文件main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
<Button
android:drawableTop="@drawable/shouru"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/button"
android:background="@drawable/selector"/>
</LinearLayout>

3.只是为了测试，所以效果不是很好，Button部分状态效果图如下：

①初始化的时候默认显示的按钮效果：

②点击后释放显示的效果

③点击不放时的效果

方法二

1.布局文件main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
<Button
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"/>
</LinearLayout>

2.主要的java代码，实现点击效果：
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;
}
});
