安卓内置语言切换

安卓内置语言切换

最近公司项目需要三种语言的实现，添加中英柬三国语言，不能跟随系统语言走，可以实现自行切换，所以开始研究下如何实现三种语言的切换。
首先你需要在你的资源文件下建立你需要的语言包

然后把你需要翻译的文字写在对应语言的xml文件中
中文

<string name="user_means">我的个人信息</string>
<string name="calear_img">清空图片缓存</string>
<string name="jiancha_gengxin">切换语言</string>
<string name="mianze">免责声明</string>
<string name="qiu_rent">求租</string>
<string name="qiu_buy">求售</string>
<string name="dai_shen">待审核</string>
<string name="dai_see">带看中</string>
<string name="yichengjiao">已成交</string>
英文

<string name="user_means">My personal information</string>
<string name="calear_img">Delete the Image</string>
<string name="jiancha_gengxin">Check for updates</string>
<string name="mianze">Disclaimer</string>
<string name="qiu_rent">Asking for rent</string>
<string name="qiu_buy">Asking for sale</string>
<string name="dai_shen">Waiting for approval</string>
<string name="dai_see">Follow up</string>
<string name="yichengjiao">Deal case</string>
柬文

<string name="user_means">ទិន្នន័យផ្ទាល់ខ្លួនរបស់ខ្ញុំ</string>

<string name="calear_img">លុបចោលរូបភាព</string>
<string name="jiancha_gengxin">ពិនិត្យមើលពត័មានថ្មីៗ</string>
<string name="mianze">ការបដិសេធ</string>
<string name="qiu_rent">ស្វែងរកការជួល</string>
<string name="qiu_buy">ស្វែងរកការលក់់</string>
<string name="dai_shen">រង់ចាំការពនិត្យសំរេច</string>
<string name="yichengjiao">case ដែលបានសំរេច</string>
然后在自己的activity中写如切换的dialog

 new AlertDialog.Builder(this)
                    .setTitle("语言切换")
                    .setIcon(android.R.drawable.ic_dialog_info)
                    .setSingleChoiceItems(new String[] { "中文", "English","ភាសាខ្មែរ" }, 3,
                            new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog,
                                                    int which) {
                                    switch (which){
                                        case 0 :
                                            language = "ch";
                                            break;
                                        case 1 :
                                            language = "en";
                                            break;
                                        case 2 :
                                            language = "km";
                                            break;
                                    }
                                }
                            }).setNegativeButton("取消", null)
                    .setNeutralButton("确定", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            dialog.dismiss();
                            SharePreUtils.newInstance(SettingActivity.this).updatlanguage(language);
                            showLanguage(language);
                            freshView();
                        }
                    }).show();

 protected void showLanguage(String language) {
    //设置应用语言类型
    Resources resources = getResources();
    Configuration config = resources.getConfiguration();
    DisplayMetrics dm = resources.getDisplayMetrics();
    if (language.equals("ch")) {
        config.locale = Locale.SIMPLIFIED_CHINESE;
    } else if(language.equals("en")){
        config.locale = Locale.ENGLISH;
    }
    else {
        config.locale = new Locale("km");
    }
    resources.updateConfiguration(config, dm);
    //保存设置语言的类型（这个里面我先保存一下，下面会讲到他的用处）
    SharePreUtils.newInstance(this).updatlanguage(language);
    //PreferenceUtil.commitString("language", language);
}

   private void freshView(){
    Intent intent = new Intent(this, SettingActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
    startActivity(intent);
}
所有代码都已经写出来了，大家可以自己自行编写。
