Question

当我点击另一个按钮时，我有多个按钮和多首歌，第一个按钮不会停止假设我有两个按钮：Button1和Button2。如果我单击Button1，则播放音频文件A.mp3。点击Button2后，音频文件A.mp3停止，B.mp3播放。然后再次单击Button1以停止B.mp3并立即播放A.mp3，依此类推。

这是我到目前为止所尝试的

final LinearLayout lm = (LinearLayout) findViewById(R.id.linearMain);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
JSONArray songs = (JSONArray) response.getJSONArray("songs");
for ( int i = 0; i < songs.length(); i++) 
{
    // Create LinearLayout
   audio = songs.getJSONObject(i).getString(TAG_AUDIO) ;
   String chanson = songs.getJSONObject(i).getString("title") ;
   String duration = songs.getJSONObject(i).getString(TAG_DURATION) ;

   LinearLayout ll = new LinearLayout(getApplicationContext());
   ll.setOrientation(LinearLayout.HORIZONTAL);

   final TextView txtchanson = new TextView(getApplicationContext());
   txtchanson.setText(chanson);
   txtchanson.setPadding(10, 0, 10, 0);
   TextView txtduration = new TextView(getApplicationContext());
   txtduration.setText(duration);

   final Button btn = new Button(getApplicationContext());
   final MediaPlayer mp = new MediaPlayer(); 
   mp.setAudioSessionId(i+1);

   mp.setDataSource(audio); 
   mp.prepare();

   btn.setId(i+1);
   btn.setTypeface(ionicons);
   btn.setText(getString(R.string.play_str));
   btn.setLayoutParams(params);

   final int index = i;

   btn.setOnClickListener(new OnClickListener() {
        @SuppressLint("ResourceAsColor")
        public void onClick(View v) {
            Log.i("TAG", "index :" + index);
            Toast.makeText(getApplicationContext(), 
                    "Clicked Button Index :" +  btn.getId(), 
                    Toast.LENGTH_LONG).show();

            if (btn.getText() == getString(R.string.play_str)) {

                btn.setText(getString(R.string.pause_str));
                txtchanson.setTextColor(R.color.green);
                mp.start();
            } else if (btn.getText() == getString(R.string.pause_str)) {
                mp.pause();
                btn.setText(getString(R.string.play_str));
                txtchanson.setTextColor(R.color.gray);
            }
        }
     });

     ll.addView(btn);
     ll.addView(txtchanson);
     ll.addView(txtduration);

     lm.addView(ll);
}

Answer 1

一旦用户点击file1，文件1就开始播放。当用户点击另一个文件时，file1暂停播放并开始播放所点击的文件。这应该发生在所有文件中。

Android - 播放和停止不同的媒体播放器，点击不同的按钮
