Android：preferencescreen從右到左

這是PreferenceScreen的xml文件 PreferenceCategory隨我需要出現RTL，但是其他組件出現LTR 如何製作thim RTL？Android：preferencescreen從右到左

我綁定遵循此link，我添加了android：supportsRtl =「true」到我的清單文件中的元素，但沒有發生任何事情！

你解決了這個問題嗎？

這有2級可能的解決方法：延長每一個喜好，並添加：

@TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR1) 
    @Override 
    protected View onCreateView(final ViewGroup paramViewGroup) 
    { 
    final View view=super.onCreateView(paramViewGroup); 
    if(VERSION.SDK_INT>=VERSION_CODES.JELLY_BEAN_MR1) 
     view.setLayoutDirection(View.LAYOUT_DIRECTION_LOCALE); 
    return view; 
    }

另一個更簡單一個是關於活動：

if(VERSION.SDK_INT>=VERSION_CODES.JELLY_BEAN_MR1) 
    getListView().setLayoutDirection(View.LAYOUT_DIRECTION_LOCALE);

然而，對於這兩種解決方法，我可以沒有找到如何通過按下一些首選項來處理顯示的對話框。

自定義CheckBoxPreference和EditTextPreference，......到正確的方向：

public class EditTextPreferenceRTL extends EditTextPreference { 

public EditTextPreferenceRTL(Context context, AttributeSet attrs) { 
    super(context, attrs); 
} 

@Override 
protected View onCreateView(ViewGroup parent) { 
    View view = super.onCreateView(parent); 

    RelativeLayout layout = (RelativeLayout) ((LinearLayout) view).getChildAt(1); 
    layout.setGravity(Gravity.RIGHT); 
    return view; 
} 
} 


public class CheckBoxPreferenceRTL extends CheckBoxPreference { 

public CheckBoxPreferenceRTL(Context context, AttributeSet attrs) { 
    super(context, attrs); 
} 

@Override 
protected View onCreateView(ViewGroup parent) { 
    View view = (LinearLayout)super.onCreateView(parent); 
    RelativeLayout layout = (RelativeLayout) ((LinearLayout) view).getChildAt(1); 
    ((LinearLayout)view).removeViewAt(1); 
    layout.setGravity(Gravity.RIGHT); 
    ((LinearLayout)view).addView(layout); 
    return view; 
} 


}
