Question

    viewPager.setOnTouchListener(
            new View.OnTouchListener() {


                @Override
                public boolean onTouch(View view, MotionEvent motionEvent) {

                    if (motionEvent.getAction() == MotionEvent.ACTION_DOWN) {
                        moved = false;
                        System.out.println("clicked ACTION_DOWN");
                    }
                    if (motionEvent.getAction() == MotionEvent.ACTION_MOVE) {
                        System.out.println("clicked ACTION_MOVE");
                        moved = true;
                    }
                    if (motionEvent.getAction() == MotionEvent.ACTION_UP) {
                        if (!moved) {
                            System.out.println("clicked ACTION_UP");
                            view.performClick();
                        }
                    }
                    return false;
                }

            }

    );

并添加了onclick监听器，如下所示

viewPager.setOnClickListener(
                new View.OnClickListener() {

                    @Override
                    public void onClick(View view) {
                                            }
                }
        );

它在samsug手机中运行良好，但华为手机不会触发MotionEvent.ACTION_UP。有人可以帮忙吗？

我通过使用GestureDetector

解决了这个问题

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

使用以下代码来处理此问题：

class TapGestureListener extends GestureDetector.SimpleOnGestureListener{

        @Override
        public boolean onSingleTapConfirmed(MotionEvent e) {
            // Your Code here
            System.out.println("hello");
                            if (e.getAction() == MotionEvent.ACTION_DOWN) {
                                moved = false;
                                viewPager.performClick();
                                System.out.println("clicked ACTION_DOWN");
                            }
                            if (e.getAction() == MotionEvent.ACTION_MOVE) {
                                System.out.println("clicked ACTION_MOVE");
                                moved = true;
                            }
                            if (e.getAction() == MotionEvent.ACTION_UP) {
                                if (!moved) {
                                    System.out.println("clicked ACTION_UP");

                                }
                            }
                            return false;
                        }

        }
    }

setOnclickListener将在此处正常工作

viewPager.setOnClickListener(
                new View.OnClickListener() {

                    @Override
                    public void onClick(View view) {
                                            }
                }
        );

ViewPager在HUAWEI手机中触发了onClick事件，但没有触发MotionEvent.ACTION_UP
