Question

我有一个ImageView作为按钮。如果我点击它，播放声音并切换到另一个活动，我想要它。单独它完美地工作，但我不能混合它们，它只能播放声音或切换活动。活动开关代码：

    public void imagebutton (View v) {
    Intent startNewActivity = new Intent(this, NewActivity.class);
    startActivity(startNewActivity);
}

声音代码：

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    final MediaPlayer sound = MediaPlayer.create(this, R.raw.clicksound);

    ImageView click = (ImageView) findViewById(R.id.imagebutton);

    click.setOnClickListener(new View.OnClickListener()

                             {
                                 @Override
                                 public void onClick (View v){
                                     sound.start();
                                 }
                             }
    );

感谢。

Answer 1

试试这个，

click.setOnClickListener(new View.OnClickListener()
     {
      @Override
       public void onClick (View v){
             sound.start();
             Intent startNewActivity = new Intent(MainActivity.this, NewActivity.class);
             startActivity(startNewActivity);
        }
     }
);

还要检查manifest.xml中的.NewActivity

Answer 2

使用您的代码启动sound.start();

下的活动

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    final MediaPlayer sound = MediaPlayer.create(this, R.raw.clicksound);

    ImageView click = (ImageView) findViewById(R.id.imagebutton);

    click.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick (View v){
            sound.start();
            Intent startNewActivity = new Intent(this, NewActivity.class);
            startActivity(startNewActivity);
        }
    }
);

Answer 3

您可以在开始新活动之前实现AsyncTask以重现您的声音。

public class BackgroundSound extends AsyncTask<Void, Void, Void> {
    @Override
    protected Void doInBackground(Void... params) {
        MediaPlayer player = MediaPlayer.create(this, R.raw.clicksound); 
        player.setLooping(true); // Set looping if you want
        player.setVolume(100,100); // Set Volume if you want
        player.start(); 
        return null;
    }
}

并使用如下：BackgroundSound.execute（）;在开始新活动之前。

您可以使用setOnCompletionListener确保声音结束然后开始新活动：

final MediaPlayer sound = MediaPlayer.create(this, R.raw.clicksound);
        sound.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            @Override
            public void onCompletion(MediaPlayer mp) {
                Intent startNewActivity = new Intent(this, NewActivity.class);
                startActivity(startNewActivity);
            }
        });
        ImageView click = (ImageView) findViewById(R.id.imagebutton);
        click.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick (View v){
                sound.start();
            }
        }
