在Android中完成按键时隐藏软键盘? [英] Hide Soft Keyboard on Done Keypress in Android?

问题描述

我正在努力使用软键盘上的完成按钮.我无法按下软键盘完成"键来隐藏键盘.通过另一个按钮，它与

I'm struggling with the done button on the soft keyboard. I can't get the soft keyboard Done key press to hide the keyboard. From another button, it works perfectly with

imm.hideSoftInputFromWindow(editText.getApplicationWindowToken(), 0);

但是onKeyListener不能按我想要的方式运行.当我按下editText时，软键盘出现，并且其内容已从字符中清除.

but the onKeyListener does not function the way I want. When I hit the editText, the soft keyboard shows up and its content is cleared from characters.

感谢您的收听！

main.xml:

<EditText 
    android:id="@+id/answer" 
    android:layout_gravity="center_horizontal" android:textSize="36px"
    android:inputType="phone"
    android:minWidth="60dp" android:maxWidth="60dp"
/>

Java文件:

private EditText editText;
//...
editText = (EditText)findViewById(R.id.answer);
editText.setOnClickListener(onKeyboard);
editText.setOnKeyListener(onSoftKeyboardDonePress);
//...

// method not working:
private View.OnKeyListener onSoftKeyboardDonePress=new View.OnKeyListener() 
{
    public boolean onKey(View v, int keyCode, KeyEvent event) 
    {
        if (event.getKeyCode() == KeyEvent.FLAG_EDITOR_ACTION)
        {
            // code to hide the soft keyboard
            imm = (InputMethodManager) getSystemService(
                Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(editText.getApplicationWindowToken(), 0);
        }
        return false;
    }
};

private View.OnClickListener onKeyboard=new View.OnClickListener() 
{
    public void onClick(View v) 
    {
        editText.setText("");
    }
};

使用按钮的工作方法(在同一java文件中):

The working method using a button (in the same java file):

private View.OnClickListener onDone=new View.OnClickListener() 
{
    public void onClick(View v) 
    {
        //....
        // code to hide the soft keyboard
        imm = (InputMethodManager) getSystemService(
            Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(editText.getApplicationWindowToken(), 0);
    }
};

编辑:当我按"9"键时，键盘隐藏了.真奇怪.

When I press key no "9" the keyboard hides. That's odd.

推荐答案

使用android:imeOptions ="actionDone"，如下所示:

Use android:imeOptions="actionDone", like that:

<EditText
    ...
    android:imeOptions="actionDone" />
