UI组件之TextView及其子类（三）ToggleButton和Switch

ToggleButton、Switch、CheckBox和RadioButton都是继承自android.widget.CompoundButton，意思是可选择的，因此它们的用法都很类似。CompoundButton有两个状态，分别是checked和not checked。 ToggleButton的属性：   Switch组件的属性：  android:thumb是选中时的背景 例：开关按钮控制布局方向 main.xml ~~~ <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <ToggleButton android:id="@+id/toggleButton1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="ToggleButton" android:textOff="横向排列" android:textOn="纵向排列" /> <!-- android:thumb="@drawable/check" 使用自定义的drawable对象绘制开关按钮 --> <Switch android:id="@+id/switch1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Switch" android:textOff="横向排列" android:textOn="纵向排列" android:thumb="@drawable/check" /> <LinearLayout android:id="@+id/root" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button1" /> <Button android:id="@+id/button2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button2" /> <Button android:id="@+id/button3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button3" /> </LinearLayout> </LinearLayout> ~~~ MainActivity.java ~~~ ToggleButton toggle; Switch switcher; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); toggle=(ToggleButton) findViewById(R.id.toggleButton1); switcher=(Switch) findViewById(R.id.switch1); final LinearLayout test=(LinearLayout) findViewById(R.id.root); //ToggleButton和Switch的监听接口和复选框CheckButton的一样 CompoundButton.OnCheckedChangeListener listener=new CompoundButton.OnCheckedChangeListener(){ @Override public void onCheckedChanged(CompoundButton button, boolean checkedId) { // TODO Auto-generated method stub if(checkedId){ //1表示垂直布局，0表示水平布局 test.setOrientation(1); }else{ test.setOrientation(0); } } }; toggle.setOnCheckedChangeListener(listener); switcher.setOnCheckedChangeListener(listener); } ~~~   以后要学会自己定制跟家美观的组件 推荐几个好的博客： [http://blog.csdn.net/billpig/article/details/6634481](http://blog.csdn.net/billpig/article/details/6634481) [http://blog.csdn.net/luoweifu/article/details/11752035](http://blog.csdn.net/luoweifu/article/details/11752035)
