不能。如果调用
setText(int resid)
,TextView
不会存储String资源的id。这个重载方法所做的就是从资源中获取String并调用setText(CharSequence text)
方法。h7appiyu2#
我唯一的解决方法是将布局xml中TextView示例的
+id
与字符串的name
匹配,然后使用参考资料将两者配对:交换部分基于交换文本字段的Gunhan Sancar's method。
这工作,但它几乎是一个黑客。
最后,我还需要改变谷歌手写输入语言编程和Juuso的亚行改变语言应用程序来超级方便。
作为参考,这里有一个使用Juuso方法的函数:
请记住将
CHANGE_CONFIGURATION
授予您的应用。这是在Android 7.1.1上测试的,但要记住,在Android 8.0(可能更高)上会失败,因为在某些构建条件下找不到
getConfiguration
(API不同)。该方法需要Locale对象的ArrayList,其中要更改为的语言位于顶部:例如
确保设备上也安装了语言。
如果你有其他的改进建议,我会非常乐意更新答案
