软件键盘删除浏览

Question

我无法找到我的问题在谷歌任何东西：

当软件键盘点击一个EditText，基本意见有时会看不见后打开/消失。它只发生在每次几次点击，而且大多数情况下，当我在打开键盘时打开AlertDialog时（即使我在打开对话框之前以编程方式关闭了键盘）。

如果我点击其他任何东西，比如EditText（它不一定要改变视图），它们会重新出现。

clipChildren设置为false。

我该如何解决这个问题？

编辑：我只是意识到我有一个无用的LinearLayout作为我的ScrollLayout的ParentView。忽略

希望这回答可以帮助你。

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; 
      } 
     }); 

或者你可以使用代码隐藏软键盘的按钮。

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

     } 
    });
