onClick()不会去下一个Activity

Question

我正在尝试转到我的应用程序的下一个活动但是onClick无法转到下一个活动.这是我迄今为止尝试过的代码.onClick播放我刚刚添加的声音.在它工作正常之前.

public class MainActivity extends Activity {

ImageButton imageButton;
Animation performAnimation1;
ImageView androidImageView;
MediaPlayer mp;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    addListenerOnButton();
    performAnimation1 = AnimationUtils.loadAnimation(this, R.layout.animation1);
    performAnimation1.setRepeatCount(4);
    androidImageView = (ImageView)findViewById(R.id.androidImageView);
    androidImageView.startAnimation(performAnimation1);

    mp = MediaPlayer.create(this, R.raw.click);
    imageButton = (ImageButton)this.findViewById(R.id.button1);
    imageButton.setOnClickListener(new View.OnClickListener() {

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

public void addListenerOnButton() {
    imageButton = (ImageButton) findViewById(R.id.button1);
    imageButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent intent = new Intent(MainActivity.this, Numbers.class);
            startActivity(intent); 
        }
    });
}

你重写onClickListenerfor R.id.button1.在您的代码中,您onClickListener在同一个按钮上设置两个不同的.而且由于是一项set操作,您将只获得最后一个实例
