Android中的Button自定义效果

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;
   }
  });
