开关按钮控件,如图,例子用于修改线性布局的横向与纵向的修改。(可以用来开关WIFI,蓝牙等)
点击横向排列或者纵向排列修改线性布局的布局格式
下面是部分Layout.xml文件
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ToggleButton
android:id="@+id/tooglebutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:textOff="横向排列"
android:textOn="纵向排列" />
<LinearLayout
android:id="@+id/mylayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="1" />
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="2" />
</LinearLayout>
</LinearLayout>
然后在MainActivity实现按钮的监听器,setOnCheckedListenner();用.setOrientation去改变线性布局的布局方向
下面是MainActivity文件
public class MainActivity extends Activity {
private ToggleButton toggleButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toggleButton = (ToggleButton) findViewById(R.id.tooglebutton);
final LinearLayout linearLayout = (LinearLayout) findViewById(R.id.mylayout);
toggleButton.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
// TODO Auto-generated method stub
if (isChecked) {
linearLayout.setOrientation(1); // 设置垂直布局
} else {
linearLayout.setOrientation(0);// 设置水平布局
}
}
});
}
