Android Word-Wrap EditText 文本 [英] Android Word-Wrap EditText text

问题描述

我一直在尝试让我的 EditText 框自动换行，但似乎无法做到.

I have been trying to get my EditText box to word wrap, but can't seem to do it.

我在开发 Android 应用程序时处理了更复杂的问题，这似乎应该是一个简单的过程.

I have dealt with much more complicated issues while developing Android applications, and this seems like it should be a straightforward process.

但是，问题仍然存在，我有一个大文本框，它只允许我在一行上输入文本，继续直行，在我输入文本时水平滚动.

However, the issue remains, and I have a large text box that is only allowing me to enter text on one line, continuing straight across, scrolling horizontally as I enter text.

这是我的布局文件中 EditText 对象的 XML 代码.

Here is the XML code for the EditText object from my layout file.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    android:id="@+id/myWidget48"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    xmlns:android="http://schemas.android.com/apk/res/android"
    >
 <ScrollView
    android:id="@+id/myScrollView"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    >
    <LinearLayout
        android:id="@+id/widget37"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
    >

<EditText
        android:id="@+id/txtNotes"
        android:layout_width="300px"
        android:layout_height="120px"
        android:scrollbars="vertical"
        android:textSize="18sp"
        android:gravity="left"
        android:layout_marginTop="10dip"
        android:inputType="textCapSentences"
        >
    </EditText>
</LinearLayout>
</ScrollView>
</LinearLayout>

推荐答案

除了找到问题的根源，我找到了解决方案.如果使用 android:inputType，则必须使用 textMultiLine 来启用多行支持.此外，使用 inputType 取代了代码 android:singleLine="false".如果使用 inputType，那么重申一下，必须使用 textMultiLine，否则 EditText 对象将仅包含一行，没有自动换行.

Besides finding the source of the issue, I found the solution. If android:inputType is used, then textMultiLine must be used to enable multi-line support. Also, using inputType supersedes the code android:singleLine="false". If using inputType, then, to reiterate, textMultiLine must be used or the EditText object will only consist of one line, without word-wrapping.

感谢Jacob Malliet就此提供进一步的好建议.他建议将 boolean scrollHorizo​​ntally 属性设置为 false，'android:scrollHorizo​​ntally="false"'.

Thank you Jacob Malliet for providing further good advice on this. He suggested to set the boolean scrollHorizontally property to false, 'android:scrollHorizontally="false"'.

示例 XML 代码:

<EditText
    android:id ="@+id/edtInput"
    android:layout_width ="0dip" 
    android:layout_height ="wrap_content" 
    android:layout_weight ="1" 
    android:inputType="textCapSentences|textMultiLine"
    android:maxLines ="4" 
    android:maxLength ="2000" 
    android:hint ="@string/compose_hint"
    android:scrollHorizontally="false" />
