Android中的可点击查看寻呼机

Question

我想在我的View Pager中设置click事件.我ViewPagerAdapter看起来像这样 -

public class ViewPagerAdapder extends PagerAdapter {

    Activity activity;
    String image[];

    public ViewPagerAdapder(Activity act, String[] imgArra) {
        image = imgArra;
        activity = act;
    }

    public int getCount() {
        return image.length;
    }

    public Object instantiateItem(View collection, final int position) {
        ImageView view = new ImageView(activity);

        view.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
                                    ViewGroup.LayoutParams.MATCH_PARENT));
        new ImageDownloaderTask(view).execute(image[position]);
        view.setScaleType(ImageView.ScaleType.CENTER_CROP);
        view.setAdjustViewBounds(true);
        ((ViewPager) collection).addView(view, 0);

    //  view.setBackgroundResource(imageArray[position]);

        return view;
    }

    @Override
    public void destroyItem(View arg0, int arg1, Object arg2) {
        ((ViewPager) arg0).removeView((View) arg2);
    }

    @Override
    public boolean isViewFromObject(View arg0, Object arg1) {
        return arg0 == ((View) arg1);
    }

    @Override
    public Parcelable saveState() {
        return null;
    }
}

我OnClickListener在我的主要活动中设置如下

 myPager = (ViewPager) view.findViewById(R.id.viewpager);

        myPager.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getActivity(), "Ckecking Success",
                        Toast.LENGTH_SHORT).show();
            }
}

我的ViewPager工作正常.我试图在Main Activity和ViewPagerAdapter类中实现OnClickListener.它无论如何都无效.

您不能将 onClickListener 用于 viewPager。您需要按以下方式使用，

将 MotionEvent 发送到 GestureDetector

tapGestureDetector = new GestureDetector(this, new TapGestureListener());

viewPager.setOnTouchListener(new OnTouchListener() {
        public boolean onTouch(View v, MotionEvent event) {
            tapGestureDetector.onTouchEvent(event);
            return false;
        }
});
