多行的EditText与2.3 Done（完成）SoftInput行动标签 [英] Multiline EditText with Done SoftInput Action Label on 2.3

问题描述

有没有办法有一个多行的EditText present并使用输入法动作标签完成在Android 2.3？

Is there a way to have a Multi-Line EditText present and use the IME Action Label "Done" on Android 2.3?

在Android 2.2的，这不是一个问题，输入按钮显示IME动作标签完成（安卓imeActionLabel =actionDone），并驳回软输入点击后。

In Android 2.2 this is not a problem, the enter button shows the IME Action Label "Done" (android:imeActionLabel="actionDone"), and dismisses Soft Input when clicked.

在配置的EditText 多行，Android 2.3的删除，显示完成行动软键盘输入的能力。

When configuring an EditText for multi-line, Android 2.3 removes the ability to show the "Done" action for the Soft Input keyboard.

我已成功地改变软输入的行为回车键使用的KeyListener ，但是输入按钮仍然看起来像一个回车键。

I have managed to alter the behaviour of the Soft Input enter button by using a KeyListener, however the enter button still looks like an enter key.

下面是声明的的EditText

<EditText
        android:id="@+id/Comment"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:layout_marginBottom="0dp"
        android:lines="3"
        android:maxLines="3"
        android:minLines="3"
        android:maxLength="60"
        android:scrollHorizontally="false"
        android:hint="hint"
        android:gravity="top|left"
        android:textColor="#888"
        android:textSize="14dp"
        />
<!-- android:inputType="text" will kill the multiline on 2.3! -->
<!-- android:imeOptions="actionDone" switches to a "t9" like soft input -->

当我加载设置的活动内容视图后检查 inputType 的价值，它显示为：

When I check the inputType value after loading setting the content view in the activity, it shows up as:

inputType = 0x20001

这就是：

• 类= TYPE_CLASS_TEXT | TYPE_TEXT_VARIATION_NORMAL
• 标记= InputType.TYPE_TEXT_FLAG_MULTI_LINE

• class = TYPE_CLASS_TEXT | TYPE_TEXT_VARIATION_NORMAL
• flags = InputType.TYPE_TEXT_FLAG_MULTI_LINE

推荐答案

好了，经过重新阅读的TextView 和 EditorInfo 的文档，它已经很清楚，该平台将迫使<一个href="http://developer.android.com/reference/android/view/inputmethod/EditorInfo.html#IME_FLAG_NO_ENTER_ACTION"><$c$c>IME_FLAG_NO_ENTER_ACTION多行文本的意见。

Well, after re-reading the TextView and EditorInfo docs, it has become clear that the platform is going to force IME_FLAG_NO_ENTER_ACTION for multi-line text views.

请注意， 的TextView 会自动   多行设置该标志您   文本视图。

Note that TextView will automatically set this flag for you on multi-line text views.

我的解决办法是子类的EditText 键，让平台上配置它们后调整输入法的选项：

My solution is to subclass EditText and adjust the IME options after letting the platform configure them:

@Override
public InputConnection onCreateInputConnection(EditorInfo outAttrs) {
    InputConnection connection = super.onCreateInputConnection(outAttrs);
    int imeActions = outAttrs.imeOptions&EditorInfo.IME_MASK_ACTION;
    if ((imeActions&EditorInfo.IME_ACTION_DONE) != 0) {
        // clear the existing action
        outAttrs.imeOptions ^= imeActions;
        // set the DONE action
        outAttrs.imeOptions |= EditorInfo.IME_ACTION_DONE;
    }
    if ((outAttrs.imeOptions&EditorInfo.IME_FLAG_NO_ENTER_ACTION) != 0) {
        outAttrs.imeOptions &= ~EditorInfo.IME_FLAG_NO_ENTER_ACTION;
    }
    return connection;
}

在上面，我强迫 IME_ACTION_DONE 也一样，尽管可以通过繁琐的布局配置来实现。

In the above, I'm forcing IME_ACTION_DONE too, even though that can be achieved through tedious layout configuration.
