我正在通过一个应用程序实现本地化示例。我使用应用程序类将所选语言更新为整个应用程序。问题是当我第一次更改语言时，它会更改为整个应用程序。同样，当我尝试更改语言时，它会给出强制关闭错误。错误出现在这一行 editor.putString("Language", getString(identifier)); 下面是我的代码和 logcat 错误。我不明白如何解决这个问题。
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
TextView mTextView = (TextView) v.findViewById(android.R.id.text1);
Toast.makeText(getActivity(), mTextView.getText().toString(), Toast.LENGTH_SHORT).show();
int identifier = getResources().getIdentifier(
mTextView.getText().toString(), "string",
getActivity().getPackageName());
String language = getString(identifier);
Toast.makeText(getActivity().getApplicationContext(), language, Toast.LENGTH_SHORT).show();
editor.clear();
editor.putString("Language", getString(identifier));
editor.commit();
changeLanguage(getString(identifier));
} /**
* Method to change the language
*
* @param localString
*/
public void changeLanguage(String localString)
{
AllUpdateApplication.updateLanguage(getActivity().getApplicationContext());
}
public class AllUpdateApplication extends Application{
/**
* Application wide language change
* @param mContext
*/
public static void updateLanguage( Context mContext){
SharedPreferences mUWBTPRefs = mContext.getSharedPreferences("language", 0);
String mLanguage = mUWBTPRefs.getString("Language", "en");
//Toast.makeText(mContext,mLanguage, Toast.LENGTH_SHORT).show();
Configuration mConfiguration = new Configuration();
mConfiguration.locale = new Locale(mLanguage);
mContext.getResources().updateConfiguration(mConfiguration, null);
}
}
