Android：水平翻转布局

Question

说我的布局有一个按钮与左边对齐，并且TextView与右边对齐。

我希望对于某些语言，布局将按原样显示，但对于其他语言，按钮应位于右侧，而文本应位于左侧。

是否有一些内置或简单的方法来动态翻转布局视图？

我可以创建一个differenet布局并动态设置内容视图，但如果有更好的建议，我宁愿避免使用此解决方案。

感谢

在这里，在我的示例代码，我改变的按钮布局点击你可以把你需要同样

if laguage = "bl bla" call layout1(); 
else call layout2(); 

我不是创建不同的布局，根据登录进来，而是相同的布局我正在动态分配不同的布局属性。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

     <Button 
     android:id="@+id/btn1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:textColor="@android:color/black" 
     android:background="@drawable/cuadrogris" 
     android:text="Button 1" 
     android:textSize="20sp" /> 

    <Button 
     android:id="@+id/btn2" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:textColor="@android:color/black" 
     android:background="@drawable/cuadrogris" 
     android:layout_below="@id/btn1" 
     android:text="Button 2"

    <Button

     android:layout_alignParentLeft="true"

    <Button

</RelativeLayout>

       RelativeLayout.LayoutParams relativeParamsright = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT); 

       relativeParamsleft.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);// helps in assging properties of relative layout that actually we easily get in XML layout 
       mbtn2.setLayoutParams(relativeParamsleft); // we need to set these layout params to the View. 

       relativeParamsright.addRule(RelativeLayout.ALIGN_PARENT_LEFT); 
       mbtn1.setLayoutParams(relativeParamsright); 

    } 

    private void layout2()
