允许的EditText，同时禁用滚动 [英] Allow EditText to Scroll while Disabled

问题描述

我有一个的EditText 设置如下：

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:descendantFocusability="beforeDescendants"
        android:focusableInTouchMode="true"
        android:orientation="vertical" >

        <EditText
            android:layout_width="match_parent"
            android:layout_height="375dp"
            android:ems="10"
            android:gravity="top">
        </EditText>

        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </LinearLayout>
</ScrollView>

在程序的某一点后，文本已被键入，在的EditText 变成由以下code禁用：

At a certain point in the program, after text has been typed, the EditText becomes disabled by the following code:

edittext.setFocusable(false);
edittext.setEnabled(false);

问题是，一旦的EditText 被禁用，我不能上下滚动，看看我写的东西。如何禁用更多的打字，但仍允许对什么是书面审查？

The problem is that, once the EditText is disabled, I can't scroll up and down to see what I've written. How do I disable more typing, but still allow for review of what's been written?

推荐答案

尝试设置的android：inputType下=textMultiLine在的EditText 。即使我已经在评论中说：有较低API错误的，但与固定高度，也许它会工作。

Try to set android:inputType="textMultiLine" on your EditText. Even if I already said in comments: there is a bug on lower API, but with the fixed height maybe it will work.

但是，如果这也不行，你应该创建另一个视图的TextView 与的EditText 并与能见度消失，如下图：

However, if this doesn't work, you should create another view as TextView with same properties of the EditText and also with visibility to gone, as follow:

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:descendantFocusability="beforeDescendants"
        android:focusableInTouchMode="true"
        android:orientation="vertical" >

        <EditText
            android:id="@+id/edittext"
            android:layout_width="match_parent"
            android:layout_height="375dp"
            android:ems="10"
            android:gravity="top" >
        </EditText>

        <TextView
            android:id="@+id/textview"
            android:layout_width="match_parent"
            android:layout_height="375dp"
            android:ems="10"
            android:gravity="top"
            android:visibility="gone" >
        </TextView>

        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </LinearLayout>
</ScrollView>  

然后，当你处理与 KeyEvent.ACTION_DOWN 的 setOnKeyListener 方法和的KeyEvent。 ACTION_ENTER ，您可以将文本复制TextView的内部和删除您的EditText：

Then, when you handle the setOnKeyListener method with KeyEvent.ACTION_DOWN and KeyEvent.ACTION_ENTER, you can copy your text inside the textview and remove your edittext:

edittext.setOnKeyListener(new OnKeyListener() {
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if ((event.getAction() == KeyEvent.ACTION_DOWN) && (keyCode == KeyEvent.KEYCODE_ENTER)) {
            String st = edittext.getText().toString();
            textview.setVisibility(View.VISIBLE);
            textview.setText(st);
            return true;
        }
        return false;
    }
});

你可以，如果你需要重写你的文字做一个反向的方法。结果
希望这有助于。

And you can do a reverse method if you need to rewrite your text.
Hope this helps.
