在我的 android 项目中，我已经成功地将 2 个字符串 [(TV ON(by button 1) and TV OFF(by button 2)] 从我的 android 手机通过 2 个简单的按钮使用 WiFi 传递到我的 PC。但在这里我需要传递 2使用单个切换按钮 [（TV ON（单击切换按钮）和 TV OFF（再次单击切换按钮）] 而不是 2 个简单按钮（上面提到）的字符串。对不起我的英语不好。感谢 adv.java 代码-

here is the correct code

  mToggleButton.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            if (mToggleButton.isChecked()) {
                messsage = "TV ON";
                Log.d("On", "Button On" + messsage);
                new Thread(new Runnable() {

                    public void run() {
                        // TODO Auto-generated method stub

                            client = new Socket("1.2.3.4", 2000);

尝试这个..

toggleButton1.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if(isChecked){

                  //do something if on

            }else{

                 //do something if off               

        }
    });

一个替代方案

 toggleButton1.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {


            if((toggleButton1.isChecked()))
            {

                 //do something if on

            }
            else
            {
                 //do something if off

            }
        }
    });
