Question

我无法在Google上找到关于我的问题的任何内容：

单击EditText后打开软件键盘时，基础视图SOMETIMES将变为不可见/消失。它只发生在每次点击几次，主要是当键盘打开时我打开一个AlertDialog（即使我在打开对话框之前以编程方式关闭键盘）。

如果我点击任何其他内容，例如EditText（它不一定要更改视图），它们会重新出现。

clipChildren设置为false。

我该如何解决这个问题？

编辑：我刚刚意识到我有一个无用的LinearLayout作为我的ScrollLayout的ParentView。忽略

希望这个答案可以帮到你。

 FrameLayout layout = (FrameLayout)findViewById(R.id.Frame);
        layout.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {

                InputMethodManager input = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                input.hideSoftInputFromWindow(v.getWindowToken(),0);

                return false;
            }
        });

或者您可以使用代码通过按钮隐藏软键盘。

    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            InputMethodManager input = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            input.hideSoftInputFromWindow(editText.getWindowToken(),0);

        }
    });
