Question

我有一个小丑按喇叭应用程序。当用户按下占据整个屏幕的图像按钮时，它会播放持续半秒钟的媒体播放器声音。

我希望它可以播放说HONK，HONK !!!和HONK !!!!!!!当该计数达到（％10 == 0）和/或（％100 == 0）语句时，随机地保留一个计数变量，该计数变量为惊人的HONKS致敬。

我添加了一个触摸按钮和一个onbuttonlistener，而且我的计数无处可去。我还希望图像按钮占据整个屏幕并在图像按钮顶部显示文本视图......

发布我的MAIN和我的XML：

public class MainActivity extends Activity implements OnTouchListener{

public void amazinghonks(View view)
{
    MediaPlayer mp = MediaPlayer.create(this, R.raw.bikehorn);
    mp.start();
}

private SoundPool soundPool;
private int soundID;
private int soundID2;
boolean loaded = false;
boolean songloaded = false;
int honkcount = 0;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    this.requestWindowFeature(Window.FEATURE_NO_TITLE);

    setContentView(R.layout.activity_main);
    View view = findViewById(R.id.toptext);
    view.setOnTouchListener(this);
    // Set the hardware buttons to control the music
    this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
    // Load the sound
    soundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);
    soundPool.setOnLoadCompleteListener(new OnLoadCompleteListener() {
        @Override
        public void onLoadComplete(SoundPool soundPool, int sampleId,
                int status) {
            loaded = true;
        }
    });
    soundID = soundPool.load(this, R.raw.bikehorn, 1);
    soundID2 = soundPool.load(this, R.raw.clown, 1);
    Toast.makeText(MainActivity.this,
            "HONK!!!", Toast.LENGTH_LONG).show();
}

@Override
public boolean onTouch(View v, MotionEvent event) {



    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        // Getting the user sound settings
        AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
        float actualVolume = (float) audioManager
                .getStreamVolume(AudioManager.STREAM_MUSIC);
        float maxVolume = (float) audioManager
                .getStreamMaxVolume(AudioManager.STREAM_MUSIC);
        float volume = actualVolume / maxVolume;
        // Is the sound loaded already?
        if (loaded && (honkcount < 3)) {
            honkcount++;
            soundPool.play(soundID, volume, volume, 1, 0, 1f);
            Log.e("Test", "Played sound");
        }

            if (songloaded && (honkcount > 10)) {
                honkcount = 0;
                soundPool.play(soundID2, volume, volume, 1, 0, 1f);
                Log.e("Test", "Played sound");
            }




    }
    return false;
}




public void addListenerOnButton() {

    ImageButton imageButton = (ImageButton) findViewById(R.id.imageButton1);

    imageButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            double randomnumber = Math.random()*101;
       //WILL HAVE THREE KINDS OF HONKS!     
            if(randomnumber < 33)
            {
           Toast.makeText(MainActivity.this,

            }
            if((randomnumber < 66)&&(randomnumber > 33))
            {

据我所知，你永远不会调用你的addListenerOnButton()方法，因此它永远不会被执行。尝试使用onCreate()方法调用它。

让ImageButton占据整个视图，顶部有TextView（如更大的z-index，对吧？）您想要使用RelativeLayout代替LinearLayout。并尝试将ImageButton的高度设置为“fill_parent”而不是0dip。高度为0将有效隐藏它，使其无法点击。
