setOnTouchListener不适用于android片段

Question

我正在使用TabView，在Tab中，我正在使用Fragment加载每个选项卡。现在，我想在用户触摸任何一个片段时获取Touch事件。我正在给我一个片段代码

 public MobileBankingFragment() {
    // Required empty public constructor
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    context = (FragmentActivity) super.getActivity();
    view = inflater.inflate(R.layout.fragment_mobile_banking, container, false);
    alarm = new TimerReceiver();
    init(view);
    touchListener(view);
    return view;
}

private void touchListener(View view) {
    layout= (FrameLayout) view.findViewById(R.id.fragmentMobileBanking);
    layout.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            Toast.makeText(context, "you just touch the screen :-)", Toast.LENGTH_SHORT).show();
            return true;
        }
    });


    view.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            Toast.makeText(context, "you just touch the screen :-)", Toast.LENGTH_SHORT).show();
            startTheTimerForTenSecond();
            return true;
        }
    });
}

这里我尝试以两种方式获取touch事件，一种是通过事件，另一种是通过布局的ID。但是没有运气。此代码没有错误，但也没有输出。帮我。

对我有效：

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_take_attendance, container, false);
    touchListener(view);
    ..
}
 private void touchListener(View view) {
        view.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if (event.getActionMasked() == MotionEvent.ACTION_DOWN){
                    Toast.makeText(getActivity(), "you just touch the screen :-)", Toast.LENGTH_SHORT).show();
                }
                return true;
            }
        });
    }

当您触摸整个片段时它会监听

Answer 2

您必须继承ViewPager的子类，并覆盖interceptTouchEvent()和onTouchEvent()，以区分滑动手势与触摸片段事件。 https://developer.android.com/training/gestures/viewgroup.html

Answer 3

您需要做的是，在clicable="true"中添加“ focusable =“ true”和fragments xml。
