Android UI设计 ToggleButton 按钮开关用法

ToggleButton是一种带状态的Button,有ON,或OFF状态，效果如下图 XML代码：

<ToggleButton android:id="@+id/tb" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content"
android:textOn="开"
android:textOff="关"
android:checked="true"
 />

textOn 按钮开启时显示的文本 textOff 按钮关闭时显示的文本 checked 载入时的状态，默认为false，即关 JAVA代码

package com.pocketdigi.togglebutton;

import android.app.Activity;
import android.os.Bundle;
import android.widget.CompoundButton;
import android.widget.Toast;
import android.widget.ToggleButton;
import android.widget.CompoundButton.OnCheckedChangeListener;

public class Main extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        ToggleButton tb=(ToggleButton)findViewById(R.id.tb);
        tb.setOnCheckedChangeListener(new OnCheckedChangeListener(){

            @Override
            public void onCheckedChanged(CompoundButton buttonView,
                    boolean isChecked) {
                // TODO Auto-generated method stub
//				isChecked就是按钮状态
                if(isChecked){
                    Toast.makeText(Main.this,"打开",Toast.LENGTH_LONG).show();
                }else{
                    Toast.makeText(Main.this,"关闭",Toast.LENGTH_LONG).show();

                }
            }
            
        });
    }
}
