我如何停止声音

Question

When I click button, first sound start, then I click button again first sound stop and second sound start. How can I do?

public void onClick(View v) {
            final MediaPlayer mp = MediaPlayer.create(getBaseContext(), R.raw.random); 
            final MediaPlayer mp2 = MediaPlayer.create(getBaseContext(), R.raw.stop);
            if(!mStarted) {
                // Start                                    
                mp2.stop();             

                mp.start();     

                Toast.makeText(finish.this, "Started!", Toast.LENGTH_SHORT).show();
                mStarted = true;
                mInterval = MIN_INTERVAL;
                mHandler.removeMessages(MESSAGE_RANDOM);               
                mHandler.sendEmptyMessage(MESSAGE_RANDOM);


            } else {
                // Stop
                generate.setEnabled(false);
                mp.stop();                          
                mp2.start();    

                mStarted = false;
                Toast.makeText(finish.this, "Stoping...", Toast.LENGTH_SHORT).show();                               
            }      
        }      
    };

Answer 1

Just add mp2.stop() before mp.start() and mp.stop() before mp2.start() . Don't forget to check if MediaPlayers are initialized and playing via calling

if (mp != null && mp.isPlaying())

for every MediaPlayer instance.

Hope this helps.

Answer 2

mp2.stop()

is code to stop MediaPlayer in general. But do you need to stop and start or this will do?

Answer 3

instead of mp2.start(); use mp2.stop();
