我试图滚动到特定点时的EditText用户点击，从而增加了以下code听单击并专注于此的EditText：

I try to scroll to specific point when the user click on edittext, so added the following code to listen to click and focus on this edittext:

    et_email = (EditText) view.findViewById(R.id.editEmail);
    //bring to center of screen when clicked / focused
    et_email.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            ScrollView scrollView = (ScrollView)getView().findViewById(R.id.ScrollViewSendDetails);
            scrollView.smoothScrollTo(0, 500);
        }
    });
    et_email.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            ScrollView scrollView = (ScrollView) getView().findViewById(R.id.ScrollViewSendDetails);
            scrollView.smoothScrollTo(0, 500);
        }
    });

问题是，滚动只有第二次点击后的作品。在关于什么的EditText第一次点击情况

The problem is that the scrolling works only after the second click. In the first click on the edittext nothing happens

推荐答案

为什么你要监听器一样吗？尝试使用onTouch监听器：

Why do you have to listener for the same? Try to use an onTouch listener:

et_email.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (MotionEvent.ACTION_DOWN == event.getAction()) {
                ScrollView scrollView = (ScrollView)getView().findViewById(R.id.ScrollViewSendDetails);
                scrollView.smoothScrollTo(0, 500);
            }
            return false;
        }
    });
