Android中的Button自定义成效

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;   }  });
