尝试这样的事情：

public class MyActivity extends Activity {
     Button buttonStart;
     Button buttonStop;

     protected void onCreate(Bundle icicle) {
         super.onCreate(icicle);

         setContentView(R.layout.content_layout_id);

         buttonStart = (Button) findViewById(R.id.buttonStart);
         buttonStop = (Button) findViewById(R.id.buttonStop);
         buttonStart.setOnClickListener(new View.OnClickListener() {
             public void onClick(View v) {
                 // Perform action on click
                 //for example mediaPlayer.start(); if you have a media player
             }
         });
         buttonStop.setOnClickListener(new View.OnClickListener(){
             public void onClick(View v){
                 //do what you want - for example mediaPlayer.stop();
             }
         });
    }
}

评论之后：然后使用一个按钮并检查它是否正在录制，例如：

public class MyActivity extends Activity {
     Button button;
     boolean isRecording = false;

     protected void onCreate(Bundle icicle) {
         super.onCreate(icicle);

         setContentView(R.layout.content_layout_id);

         button = (Button) findViewById(R.id.myButton);
         button.setText("Start");
         button.setOnClickListener(new View.OnClickListener() {
             public void onClick(View v) {
                 // Perform action on click
                 if(isRecording == fasle){
                     //start recording
                     isRecording = true; //set the variable to know that it is recording
                     button.setText("Stop");
                 } else {
                     //stop recording
                     isRecording = false; //set the variable to know that it is not recording
                     button.setText("Start");
                 }
             }
         });
    }
}

如果您想要完全相同（即2个按钮）

您可以使用relativelayout，并在其中添加两个按钮。

您可以通过编程方式显示/隐藏它们，如：

public void onClick(View v) 
    {
      switch(v.getId()) {
      case R.id.btn1:
       btn1.setVisibility(View.GONE);
       btn2.setVisibility(View.VISIBLE);
     break;

    case R.id.btn2:
     btn2.setVisibility(View.GONE);
     btn1.setVisibility(View.VISIBLE);
    break;
   }
 }

否则， you can even use one button for both the functionalities (start and stop) 为 -

    public void onClick(View v) 
   {
    if(btn1.getText().toString().equalsIgnoreCase("start"))
    {
        btn1.setText("stop");
        mp2.start();
        musicPlaying = true;
    }
    else if(btn1.getText().toString().equalsIgnoreCase("stop"))
    {
        btn1.setText("start");
        mp2.stop();
        musicPlaying = false;
    }
}

两个按钮与onClick在同一个地方
