        android:layout_height="wrap_content"
        android:checked="false"

main.java

package com.wwtiot.test;
import android.app.Activity;

import android.view.Menu;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.ImageView;
import android.widget.ToggleButton;
public class Main extends Activity implements OnCheckedChangeListener{
private ToggleButton toggleButton1;
private ImageView imageView1;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  
  //初始化控件
  toggleButton1=(ToggleButton)findViewById(R.id.toggleButton1);
  imageView1=(ImageView)findViewById(R.id.imageView1);
  
  //对ToggleButton添加监听事件
  toggleButton1.setOnCheckedChangeListener(this);
 }
 
 @Override
 public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
  //更改toggleButton1的状态checked属性
  toggleButton1.setChecked(isChecked);
  
  imageView1.setBackgroundResource(isChecked?R.drawable.light_on408x531:R.drawable.light_off408x531);
 }
