Set upper case for TextView
提问by Tim
I have TextView. I would like to show text in upper case mode. Is there attributed for upper case? Just I have text in strings.xml and I need use the line in several place as lower case and upper case.
我有文本视图。我想以大写模式显示文本。是否有大写的归属？只是我在 strings.xml 中有文本，我需要在几个地方使用该行作为小写和大写。

In the layout XML, you can set the android:textAllCapsattribute on your TextView:
在布局 XML 中，您可以android:textAllCaps在您的TextView:
<TextView android:textAllCaps="true"></TextView>

Use Stringclass method while setting the text to TextViewas
使用String类的方法，而文本设置TextView为
tv.setText(strings.toUpperCase());
Have a look at thispost for detail discussion.

EDIT:This was answered way back before API 14. As other answer mentioned here, textView.isAllCaps = trueand its java methods were introduced from TextView. Please use those.

回答by calsign
For an XML approach, you don't want to use android:capitalizebecause this is intended for use during text input. Instead, use textAllCaps. If your strings are declared as lower case, then it is quite simple to toggle between upper and lower case on a per-TextView basis.
对于 XML 方法，您不想使用，android:capitalize因为它旨在在文本输入期间使用。相反，使用textAllCaps。如果您的字符串被声明为小写，那么在每个 TextView 的基础上在大写和小写之间切换是非常简单的。

尝试这个。
Upper Case
大写
textView.setText(getResources().getString(R.string.app_name).toUpperCase());
Lower Case
小写
textView.setText(getResources().getString(R.string.app_name).toLowerCase());
回答by Sameer
You could create a custom view derived from TextView and override the setText method to capitalize.
您可以创建一个从 TextView 派生的自定义视图并覆盖 setText 方法以进行大写。
