从两个不同的按钮播放两个不同的声音文件？ [英] Play two different sound files from two different buttons?

问题描述

我在许多地方寻找这一点，但无法找到答案。我想提出一个应用了一组对他们的字母表图像按钮。我希望能够点击字母A，听到声音文件A.如果我点击字母B，我想听到的声音文件B.到目前为止我只有字母A和B，和声音文件A和B.当我运行我的code，我只能听到声音的按钮A，当我preSS字母B，什么也没有发生。这是我的code：

I tried searching for this in many places, but could not find an answer. I am making an app with a set of image buttons that have the alphabet on them. I want to be able to click the letter A, and hear sound file A. If I click letter B, I want to hear sound file B. So far I only have letters A and B, and sound files A and B. When I run my code, I can only hear the sound for button A, and when I press letter B, Nothing happens. This is my code:

    package com.android.nishad.learn.hindi;

    import android.app.Activity;
    import android.media.MediaPlayer;
    import android.os.Bundle;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.ImageButton;

    public class AlphabetActivity extends Activity implements OnClickListener {
       /** Called when the activity is first created. */
       MediaPlayer mp;

       @Override
       public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_alphabet);

          ImageButton btn = (ImageButton)findViewById(R.id.imageButton1);
          btn.setOnClickListener(this);

       }

       public void onClick(View v) {
          // TODO Auto-generated method stub

          mp = MediaPlayer.create(this, R.raw.lettera);
          mp.start();
          while (mp.isPlaying()) { 
             // do nothing 
          };
          mp.release();
       }



       public void onCreate1(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_alphabet);

          ImageButton btn2 = (ImageButton)findViewById(R.id.imageButton2);
          btn2.setOnClickListener(this);

       }

       public void onClick1(View v) {
          // TODO Auto-generated method stub

          mp = MediaPlayer.create(this, R.raw.letterb);
          mp.start();
          while (mp.isPlaying()) { 
             // do nothing 
          };
          mp.release();
       }
    };
