带有多行提示的 EditText

发布于 2024-10-07 05:13:17 字数 473 浏览 1 评论 0原文

我有一个大的 EditText 框。我希望框中的提示看起来像这样（不是有意的语法突出显示）：

Hint about the first line
Hint about the second line
Hint about the third line

我尝试在 EditText 上使用 android:hint="@string/hints" 以及在 strings.xml 中，但提示仍然在一行上。

<string name="hints">
Hint about the first line
Hint about the second line
Hint about the third line
</string>

如何在 EditText 中获取多行提示？

原文

I have a large EditText box. I want a hint in the box to look like this (syntax highlight not intended):

Hint about the first line
Hint about the second line
Hint about the third line

I tried using android:hint="@string/hints" on the EditText with the following in strings.xml, but the hint was still on a single line.

<string name="hints">
Hint about the first line
Hint about the second line
Hint about the third line
</string>

How can one obtain a multiline hint in an EditText?

您可以通过显式指定在字符串中包含换行符：

<string name="hint">Manny, Moe and Jack\nThey know what I\'m after.</string>

XML 中的换行符被视为空格。

You can include newlines in strings by explicitly specifying them:

<string name="hint">Manny, Moe and Jack\nThey know what I\'m after.</string>

Newlines in the XML are treated as spaces.

为每一行创建一个单独的字符串资源：

<string name="hint_one">Hint about the first line</string>
<string name="hint_two">Hint about the second line</string>
<string name="hint_three">Hint about the third line</string>

不要在布局 XML 中包含 android:hint 属性。在创建 EditText 的位置，手动设置提示：

// get the string values
final Resources res = getResources();
final String one   = res.getString(R.string.hint_one);
final String two   = res.getString(R.string.hint_two);
final String three = res.getString(R.string.hint_three);

// set the hint
final EditText et = (EditText) findViewById(R.id.some_edit_text);
et.setHint( one + "\n" + two + "\n" + three );

Make a separate string resource for each line:

<string name="hint_one">Hint about the first line</string>
<string name="hint_two">Hint about the second line</string>
<string name="hint_three">Hint about the third line</string>

don't include an android:hint attribute in your layout XML. Where the EditText is created, set the hint manually:

// get the string values
final Resources res = getResources();
final String one   = res.getString(R.string.hint_one);
final String two   = res.getString(R.string.hint_two);
final String three = res.getString(R.string.hint_three);

// set the hint
final EditText et = (EditText) findViewById(R.id.some_edit_text);
et.setHint( one + "\n" + two + "\n" + three );
