我正在开发一个我正在使用片段的 android 应用程序。并且在单击列表项后，我将语言从英语更改为阿拉伯语，并且工作正常。

但是我希望即使我们从设备强制关闭应用程序后，所选语言仍保留在整个应用程序中......但这不会发生在我身上......

如果我与 Activity 一起使用，那么我有电话

setContentView(R.layout.main);

在 onResume() 方法和它的工作正常。

但我的问题是，我们如何设置带有片段的视图或在 onResume() 方法上调用 onCreateView 方法，因为 onCreateView() 方法返回自己的视图。所以尝试了很多来解决它，但我不能。所以请有什么办法解决吗？？

提前致谢。

这是我的代码：

package com.example.okazz.Settings;

import java.util.Locale;

import android.app.Activity;
import android.content.Context;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;

import com.example.okazz.R;

public class Languages extends Fragment {
// private int current = -1;
View view;
Context ct;
SharedPreferences sp1, sp;
Boolean Ischeck = false;
String User_id, countryid;
Button settings;
String[] arrLanguages = new String[] { "English", "Arabic" };
String req;
ListView lv;
private Locale myLocale;

public Languages(Context c) {

    this.ct = c;
}

/** Called when the activity is first created. */
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // TODO Auto-generated method stub

    view = inflater.inflate(R.layout.languagechange, container, false);

    SharedPreferences sp = getActivity().getSharedPreferences("key", 0);
    User_id = sp.getString("userid=", User_id);
    countryid = sp.getString("countryid", countryid);
    settings = (Button) view.findViewById(R.id.btnsett);
    lv = (ListView) view.findViewById(android.R.id.list);
    lv.setAdapter(new MobileArrayAdapter(ct, arrLanguages));
    settings.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            FragmentManager manager = getFragmentManager();
            manager.popBackStack();
            Log.d("Back to Home", "back button pressed");
        }
    });

    lv.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {

            // get selected items
            String selectedValue = (String) lv.getAdapter().getItem(
                    position);
            Toast.makeText(ct, selectedValue, Toast.LENGTH_SHORT).show();
            // setResult(RESULT_OK, new Intent().putExtra("language",
            // arrLanguages[position]));
            // Configuration config = new Configuration();
            String lang = null;
            switch (position) {
            case 0:
                lang = "en";

            // }

        }

    });
    return view;
}

public void loadLocale() {

您的问题有点难以阅读，但我想我明白了：您想随着语言的变化重新布局片段。

我想最好的片段可能是删除片段，然后将新实例重新添加到您的活动中。

另一种选择是使用活动及其内部片段的 onConfigurationChange 方法：更改语言环境：强制活动重新加载资源？.

您可以通过执行以下操作自己触发此事件：

int lang = //the result of your click inside the list item
Resources res = getResources();
DisplayMetrics dm = res.getDisplayMetrics();
Configuration conf = res.getConfiguration();

switch(lang){
    case ARABIC:
        conf.locale = Locale.WHATEVER;
        break;

    case ENGLISH:
        conf.locale = Locale.ENGLISH;
        break;
}
res.updateConfiguration(conf, dm);

您可以使用SharedPreferences保存您的语言偏好，并在 onCreate 中使用首选语言重新创建视图
