如何处理ImeOptions的“完成”按钮单击？

Question

我有一个EditText，其中我设置了以下属性，以便当用户单击EditText时可以在键盘上显示done按钮。

editText.setImeOptions(EditorInfo.IME_ACTION_DONE);

当用户单击屏幕键盘上的done按钮(完成键入)时，我想要更改RadioButton状态。

从屏幕键盘点击完成按钮时，如何跟踪完成按钮？

我最终得到了Roberts和chirags的组合答案：

((EditText)findViewById(R.id.search_field)).setOnEditorActionListener(
        new EditText.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        // Identifier of the action. This will be either the identifier you supplied,
        // or EditorInfo.IME_NULL if being called due to the enter key being pressed.
        if (actionId == EditorInfo.IME_ACTION_SEARCH
                || actionId == EditorInfo.IME_ACTION_DONE
                || event.getAction() == KeyEvent.ACTION_DOWN
                && event.getKeyCode() == KeyEvent.KEYCODE_ENTER) {
            onSearchAction(v);
            return true;
        }
        // Return true if you have consumed the action, else false.
        return false;
    }
});

更新：上面的代码有时会激活两次回调。相反，我选择了以下代码，这是我从Google聊天客户端获得的代码：

public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
    // If triggered by an enter key, this is the event; otherwise, this is null.
    if (event != null) {
        // if shift key is down, then we want to insert the '\n' char in the TextView;
        // otherwise, the default action is to send the message.
        if (!event.isShiftPressed()) {
            if (isPreparedForSending()) {
                confirmSendMessageIfNeeded();
            }
            return true;
        }
        return false;
    }

    if (isPreparedForSending()) {
        confirmSendMessageIfNeeded();
    }
    return true;
}

试试这个，它应该能满足你的需求：

editText.setOnEditorActionListener(new EditText.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
    if (actionId == EditorInfo.IME_ACTION_DONE) {
       //do here your stuff f
       return true;
    }
    return false;
    } 
});

<EditText android:imeOptions="actionDone"
          android:inputType="text"/>

Java代码是：

edittext.setOnEditorActionListener(new OnEditorActionListener() { 
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_DONE) {
            Log.i(TAG,"Here you can write the code");
            return true;
        }    
        return false;
    }
});
