片段代码:

@Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container,
                             @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.add_payment_fragment, container, false);
        view.findViewById(R.id.add_pay_time).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getContext(), "aaaa", Toast.LENGTH_LONG).show();
            }
        });
        return view;

编辑文本需要 focus 打电话 onClick() .
解决方案1
设置侦听器时请求焦点:

EditText editText = view.findViewById(R.id.add_pay_time);
editText.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Toast.makeText(getContext(), "aaaa", Toast.LENGTH_LONG).show();
    }
});
editText.requestFocus(); //request focus

解决方案2
设置触控监听器:

EditText editText = view.findViewById(R.id.add_pay_time);
editText.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (MotionEvent.ACTION_DOWN == event.getAction())
            Toast.makeText(getContext(), "aaaa", Toast.LENGTH_LONG).show();
        return false;
    }
});

解决方案3
你可以用 onClickListener 以及 onFocusChangeListener 一起:

EditText editText = view.findViewById(R.id.add_pay_time);
editText.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        showToast();//call your method
    }
});

editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus)
            showToast();//call your method
    }
});

EditText edText = view.findViewById(R.id.add_pay_time);
        edText.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Toast.makeText(getActivity(), "aaaa", Toast.LENGTH_LONG).show();
                }
            });
