有没有办法自动设置所有布局，以支持Android中的RTL和LTR方向类型的语言 [英] Is there any way to automatically set the all layouts to support for both RTL and LTR direction types of languages in android

问题描述

我是android开发的新手，坚持改变整个 android 应用程序的语言。我找到了一种方法将字符串设置为 strings-languagecode in values 目录和 android：supportsRtl =true在清单文件中，它更适合更改文本字段的值和他们的方向 LTR 和 RTL 自动但我在 EditText中遇到问题字段，因为它的方向需要由每个 xml 文件的Java代码更改和设置。有没有办法在整个应用程序中以最小的努力自动设置 EditText 的方向？请注意我的项目中最低 api等级15 。请帮帮我。

I am new in android development, stuck to change the language of the whole android application. i found a way to set the strings into strings-languagecode in values directory and android:supportsRtl="true" in manifest file, it is good for changing the value of the text fields and their direction LTR and RTL automatically but I am getting the problem in EditText field because it's direction needs to be changed and set by the Java code for every xml file. Is there any way to set the direction of the EditText automatically in whole application with minimum effort? Please note I have minimum api level 15 in my project. Please help me out.

提前致谢。

推荐答案

你可以尝试这些方法来改变RTL或LTR布局方向。

You can try these methods to change RTL or LTR layout directions.

对于左转：

ex。 locale：Arabic（ar），Hebrew（he）;

ex. locale : Arabic(ar), Hebrew(he);

private void setRtl(){
    String languageToLoad  = "ar"; // rtl language Arabic
    Locale locale = new Locale(languageToLoad);  
    Locale.setDefault(locale); 

    Configuration config = new Configuration(); 
    config.locale = locale; 
    getBaseContext().getResources().updateConfiguration(config,  
            getBaseContext().getResources().getDisplayMetrics());
            //layout direction 
    Bidi b = new Bidi(languageToLoad,Bidi.DIRECTION_DEFAULT_RIGHT_TO_LEFT);
            b.isRightToLeft();
    //save current locale in SharedPreferences
    SharedPreferences languagepref = getSharedPreferences("language",MODE_PRIVATE);
    SharedPreferences.Editor editor = languagepref.edit();
    editor.putString("languageToLoad",languageToLoad );
    editor.commit(); 

    startActivity(...);// refresh activity.
}

左转：

ex locale：English（en），Tamil（ta）。等。

ex locale : English(en), Tamil(ta)., etc.

private void setLtr(){
   String languageToLoad  = "en"; // ltr language English
   Locale locale = new Locale(languageToLoad);  
   Locale.setDefault(locale); 

   Configuration config = new Configuration(); 
   config.locale = locale; 
   getBaseContext().getResources().updateConfiguration(config,  
        getBaseContext().getResources().getDisplayMetrics());
        //layout direction 
   Bidi b = new Bidi(languageToLoad, Bidi.DIRECTION_DEFAULT_LEFT_TO_RIGHT);
            b.isLeftToRight();
   //save current locale in SharedPreferences
   SharedPreferences languagepref = getSharedPreferences("language",MODE_PRIVATE);
   SharedPreferences.Editor editor = languagepref.edit();
   editor.putString("languageToLoad",languageToLoad );
   editor.commit(); 

   startActivity(...);// refresh activity.

}
