java - Android If 语句用于多个 setOnClickListener

Question

我有多个 setOnClickListener，我想做的是，让它更简单。

这是我的java

 @Override
public void onActivityCreated(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onActivityCreated(savedInstanceState);

    // get the button view
    ImageView foodImg = (ImageView) getView().findViewById(R.id.iconFoods);
    ImageView barsImg = (ImageView) getView().findViewById(R.id.iconBars);
    ImageView roomsImg = (ImageView) getView().findViewById(R.id.iconRooms);
    ImageView wellnessImg = (ImageView) getView().findViewById(R.id.iconWellness);
    ImageView beachesImg = (ImageView) getView().findViewById(R.id.iconBeaches);
    ImageView kidsImg = (ImageView) getView().findViewById(R.id.iconKids);
    ImageView attractionsImg = (ImageView) getView().findViewById(R.id.iconAttractions);
    ImageView shopsImg = (ImageView) getView().findViewById(R.id.iconShops);
    ImageView museumsUmg = (ImageView) getView().findViewById(R.id.iconMuseum);

    // set a onclick listener for when the food button gets clicked
    foodImg.setOnClickListener(new OnClickListener() {

        // Start new list activity
        public void onClick(View v) {
            Intent mainIntent = new Intent(getActivity(),
                    Food.class);
            startActivity(mainIntent);
        }
    });

    // set a onclick listener for when the bars button gets clicked
    barsImg.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            Intent mainIntent = new Intent(getActivity(),
                    Bars.class);
            startActivity(mainIntent);
        }
    });

如您所见，我为每个 ImageView 创建了一个 setOnClickListener。我的问题是，如何对多个 setOnClickListener 使用 if 语句？因此，当我单击 ImageView Foods 图标时，我打开了 Food Activity 。谢谢之前:D

创建一个通用的onClickListener

    private OnClickListener onClickListener = new OnClickListener() {
        @Override
        public void onClick(final View v) {
            switch(v.getId()){
                case R.id.button1:
                    ((TextView) getView().findViewById(R.id.textView1)).setText("Button 1 pushed");
                    break;
                case R.id.button2:
                    ((TextView) getView().findViewById(R.id.textView1)).setText("Button 2 pushed");
                    break;
                case R.id.button3:
                    ((TextView) getView().findViewById(R.id.textView1)).setText("Button 3 pushed");
                    break;
              }
        }
    };

然后将每个 View 设置为使用该点击监听器，即:

        Button btn1 = (Button) getView().findViewById(R.id.button1);
        Button btn2 = (Button) getView().findViewById(R.id.button2);
        Button btn3 = (Button) getView().findViewById(R.id.button3);

        btn1.setOnClickListener(onClickListener);
        btn2.setOnClickListener(onClickListener);
        btn3.setOnClickListener(onClickListener);

希望有帮助。
