ToggleButton的使用有感

今天用到ToggleButton开关按钮，由于给他设置错了监听事件，效果不是所想 原来用的多的还是监听状态的改变。写一个例子，显示效果才明白。

package com.rotunda.test;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.CompoundButton;
import android.widget.TextView;
import android.widget.ToggleButton;

public class ToggleButtonTest extends Activity {
    /** Called when the activity is first created. */
	private ToggleButton tg;
	private TextView tv,tvc;
	private static boolean ischecked=false;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        tg=(ToggleButton)findViewById(R.id.togglebutton_displaychart_showgrid);
        tv=(TextView)findViewById(R.id.textview_main_showtest);
        tvc=(TextView)findViewById(R.id.textview_main_showclick);
//        tg.setOnCheckedChangeListener(tgcheckedlistener);
        tg.setOnClickListener(tgclicklistener);
//        this.p
    }
    ToggleButton.OnClickListener tgclicklistener=new OnClickListener()
    {

		public void onClick(View v) {
			// TODO Auto-generated method stub
		if(ischecked)	
		{
			tvc.setText("click ischecked");
		}
		else
		{
			tvc.setText("click not checked");
		}
		}
    	
    };
    ToggleButton.OnCheckedChangeListener tgcheckedlistener=new  ToggleButton.OnCheckedChangeListener()
    {

		public void onCheckedChanged(CompoundButton buttonView,
				boolean isChecked) {
			// TODO Auto-generated method stub
			if(isChecked)
			{
				tv.setText("checked");
				ischecked=true;
				System.out.println("ischecked==="+ischecked);
			}
			else
			{
				tv.setText("not checked");
				ischecked=false;
				System.out.println("ischecked==="+ischecked);
			}
		}
    	
    };
}

其中对应的配置文件是

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView 
    android:id="@+id/textview_main_showtest"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    />
   <TextView 
    android:id="@+id/textview_main_showclick"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    />
    <ToggleButton
 android:id="@+id/togglebutton_displaychart_showgrid"
 android:layout_width="70dip"
 android:layout_height="wrap_content"
 android:layout_marginLeft="10dip"
 android:textOff="网格"
 android:textOn="网格"
 />
</LinearLayout>
可以试着观察一下来了解
