Android onClick（）不进入下一个活动

我正在尝试转到应用程序的下一个活动，但onClick无法转到下一个活动。这是我的代码，我已经试过了。onClick播放我刚才添加的声音。在它正常工作之前

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); 
        }
    });
}

}

Mainfest.xml

您覆盖R.id.button1的onClickListener。在代码中，在同一个按钮上设置了两个不同的onClickListener。因为这是一个集合操作，所以您只能得到最后一个实例

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) {
        // TODO Auto-generated method stub

        mp.start();

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

}

移除addListenerOnButton；在调用mp.start的同一个lintner中，从您的代码和start活动开始；i、 e

从oncreate中删除以下代码

 imageButton = (ImageButton)this.findViewById(R.id.button1);
    imageButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            mp.start();
        }
    });

或者从您的活动中删除代码

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); 
        }
    });
}

您所做的是覆盖了R.id.button1的onClickListener，这是不正确的

 imageButton = (ImageButton)this.findViewById(R.id.button1);
    imageButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            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); 
        }
    });
}
