Question

我正在尝试开发一个Android应用程序，在一段时间之后我们必须在文本框中显示一定时间后的值。到目前为止，我只能显示2个值。我也试图将值放在数组中，但到目前为止一直没有成功我正在下载我的代码。任何想法都会有所帮助。那么有一个按钮，按下按钮后，文本框中会出现第一个值。这是62.53。我第二次点击buttopn后，我看到另一个值72.5。我连续10次点击按钮后，我愿意显示10个值。我无法这样做。这是我的问题

public void onClick（查看v）{

     if (recording) {

         recorder.stop();

        // recorder.release();

         recording = false;

         Log.d("Test","recorderonclick");

        // Stop Thread

         MobilityMonitorV2.setRunning(false);

         button.setText(R.string.titleStart);

         Log.d("Test","recorderclick");

         // Upload Files to Server

         UploadThread upThread = new UploadThread(

                MobilityMonitorV2.TIMESTAMP, handler);

         upThread.start();

         Log.d("Test","recorderonclick");

        initRecorder();

         setOutputFile(false);

         prepareRecorder();

        Log.d("TEst","recordercick");





        final TextView textView = (TextView) findViewById(R.id.editText1);



         textView.setText("62.53"); 

        String editTextStr = textView.getText().toString();

         String string = getString(R.string.hello);

        //recorder.reset();

         button.setOnClickListener(new OnClickListener() {



                       public void onClick(View v) {









                                 textView.setText("72.5");  



                        }

                        });





    }






    else {

         resetRecorder();

        initRecorder();

         setOutputFile(true);

         prepareRecorder();

        recording = true;

         recorder.start();

         Log.d("Test","recorderreset");




        // Start Bluetooth data thread

         DataStream dataStream = new DataStream();

        dataStream.start();

         Log.d("Test","bluetoothdataset");



        button.setText(R.string.titleStop);

         Log.d("Test","buttonsetstop");

        //TextView textView1 = (TextView) findViewById(R.id.editText1);  

         //textView1.setText("62.5");  

    }



 }


            }

未测试!!

private TextView textView1;
private static int mCounter = 0;

private ArrayList<String> values = new ArrayList<String>();

public void onCreate(Bundle savedInstanceState)
{

    // Add the values you would like to show
    values.add("62.53");
    values.add("72.5");
    // etc. etc.

    // Get a reference to your textview
    textView1 = (TextView) findViewById(R.id.editText1);  

    // Set a click listener
    textView1.setOnClickListener(new OnClickListener()
    {
        public void onClick(View v)
        {
            // Get the value from your arraylist
            String value = values.get(mCounter);

            // Set the value in your textview
            textView1.setText(value);

            // Increase the counter
            mCounter++;
        }
    });
}

Android在android文本框中的特定时间后显示不同的值
