这个小例子主要用来演示ToggleButton的基本使用。效果大致是一开始界面是垂直布局的,当点击ToggleButton按钮的时候,布局变为水平方向的
大致的代码贴一下吧,其中main.xml代码如下:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <ToggleButton android:id="@+id/toggleButton1" 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/lLayout" 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="Button" /> <Button android:id="@+id/button2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> <Button android:id="@+id/button3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> </LinearLayout> </LinearLayout>
AndroidDemo4Activity.java代码如下:
package android.demo; import android.app.Activity; import android.os.Bundle; import android.widget.CompoundButton; import android.widget.CompoundButton.OnCheckedChangeListener; import android.widget.LinearLayout; import android.widget.ToggleButton; public class AndroidDemo4Activity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ToggleButton toggle=(ToggleButton)findViewById(R.id.toggleButton1); final LinearLayout layout=(LinearLayout)findViewById(R.id.lLayout); toggle.setOnCheckedChangeListener(new OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton arg0, boolean arg1) { if(arg1){ //设置垂直布局 layout.setOrientation(1); }else{ //设置水平布局 layout.setOrientation(0); } } }); } }
