保持软键盘打开时进入关键是pressed [英] Keep soft keyboard open when enter key is pressed

问题描述

嗯，我从收盘试图prevent软键盘，当用户preSS的确定按钮编辑的文本字段后。 其实，我想要实现的是：当确定按钮是pressed，现场解析，如果有效，它开始另一个活动。 这是很容易的。

Well, I'm trying to prevent the soft keyboard from closing when the user press the "ok" button after editing a text field. Actually, what i'm trying to achieve is : when "ok" button is pressed, the field is parsed and if valid, it starts another activity. That is easy enough.

不过，当字段是无效的，我想软键盘保持打开状态。 这是......地狱更复杂。 如果有人知道如何实现这样的事情......

But, when the field is not valid, I want the soft keyboard to stay open. And that's... a hell more complicated. If anyone know how to achieve such a thing...

在此先感谢。

编辑：我的意思OK按钮是软键盘的OK按钮

EDIT : what I mean by the OK button is the OK button from the soft keyboard.

推荐答案

连接<一href="http://developer.android.com/reference/android/widget/TextView.OnEditorActionListener.html"><$c$c>OnEditorActionListener你的文本字段，并返回真从 onEditorAction 方法，当 actionId 的等于<一href="http://developer.android.com/reference/android/view/inputmethod/EditorInfo.html#IME_ACTION_DONE">IME_ACTION_DONE.这将prevent软键盘的隐藏：

Attach OnEditorActionListener to your text field and return true from its onEditorAction method, when actionId is equal to IME_ACTION_DONE. This will prevent soft keyboard from hiding:

EditText txtEdit = (EditText) findViewById(R.id.txtEdit);
txtEdit.setOnEditorActionListener(new OnEditorActionListener() {

  public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
    if (actionId == EditorInfo.IME_ACTION_DONE) {
      // your additional processing... 
      return true;
    } else {
      return false;
    }
  }

});
