How to right align PreferencesActivity in android?

Question

I have PreferencesActivity which I need it to be right aligned because I want to use Arabic language, I tried to use android:layout_gravity=\"right\"

Answer 1

After checking for a few solutions i came upon something that might help. It's not elegant and works only on 4 and up but it's better than nothing...

add this code to onResume()

    Locale locale = new Locale("iw");// Hebrew in this case
    Locale.setDefault(locale);
    Configuration config = new Configuration();
    config.locale = locale;
    getBaseContext().getResources().updateConfiguration(config,
          getBaseContext().getResources().getDisplayMetrics());

Of course you can choose to change the locale in your preference activities onResume() method only in your MainActivity's onResume() change locale back to your preferred (or user defined) locale.

Hope this helps!

public class RtlEditTextPreference extends EditTextPreference {

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

    RelativeLayout relativeLayout = (RelativeLayout)(((LinearLayout)view).getChildAt(1));
    relativeLayout.setGravity(Gravity.RIGHT);

    TextView title = (TextView) relativeLayout.getChildAt(0);
    TextView summary = (TextView) relativeLayout.getChildAt(1);

    RelativeLayout.LayoutParams titleLayoutParams = (RelativeLayout.LayoutParams)title.getLayoutParams();
    titleLayoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
    title.setLayoutParams(titleLayoutParams);

    RelativeLayout.LayoutParams summaryLayoutParams = (RelativeLayout.LayoutParams)summary.getLayoutParams();
    summaryLayoutParams.addRule(RelativeLayout.ALIGN_RIGHT, title.getId());
    summaryLayoutParams.addRule(RelativeLayout.ALIGN_LEFT, -1); // Override default left alignment to the title
    summary.setLayoutParams(summaryLayoutParams);

    return view;
}

}

Answer 4

same as my problem and this is the solution:

inside your PreferenceFragment:

@Override
    public View onCreateView(LayoutInflater paramLayoutInflater,
            ViewGroup paramViewGroup, Bundle paramBundle) {
        getActivity().setTitle(R.string.fragment_title_settings);
        View v = super.onCreateView(paramLayoutInflater, paramViewGroup,
                paramBundle);
        rtlView(v);
        return v;
    }
    public void rtlView(View v){
        if(v instanceof ListView){
            rtllater((ListView) v);
        }
        else
        if(v instanceof ViewGroup){
            if(v instanceof RelativeLayout){
                ((RelativeLayout)v).setGravity(Gravity.RIGHT);
            }
            else
            if(v instanceof LinearLayout){
                ((LinearLayout)v).setGravity(Gravity.RIGHT);
            }
            for (int i=0;i<((ViewGroup)v).getChildCount();i++){
                rtlView(((ViewGroup)v).getChildAt(i));
            }
        }
        else
            if(v instanceof TextView){
                v.getLayoutParams().width=v.getLayoutParams().MATCH_PARENT;
                ((TextView)v).setGravity(Gravity.RIGHT);
            }
    }
    public void rtllater(ListView v){
        v.setOnHierarchyChangeListener(new ViewGroup.OnHierarchyChangeListener() {
            @Override
            public void onChildViewAdded(View view, View view1) {
                rtlView(view1);
            }
            @Override
            public void onChildViewRemoved(View view, View view1) {

            }
        });
    }

the result is like this image:right to left Preference

public class RtlEditTextPreference extends EditTextPreference {
public RtlEditTextPreference(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public RtlEditTextPreference(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

public RtlEditTextPreference(Context context) {
    super(context);
}

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

    RelativeLayout relativeLayout = (RelativeLayout)(((LinearLayout)view).getChildAt(1));
    relativeLayout.setGravity(Gravity.RIGHT);

    TextView title = (TextView) relativeLayout.getChildAt(0);
    TextView summary = (TextView) relativeLayout.getChildAt(1);

    RelativeLayout.LayoutParams titleLayoutParams = (RelativeLayout.LayoutParams)title.getLayoutParams();
    titleLayoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
    title.setLayoutParams(titleLayoutParams);

    RelativeLayout.LayoutParams summaryLayoutParams = (RelativeLayout.LayoutParams)summary.getLayoutParams();
    summaryLayoutParams.addRule(RelativeLayout.ALIGN_RIGHT, title.getId());
    summaryLayoutParams.addRule(RelativeLayout.ALIGN_LEFT, -1); // Override default left alignment to the title
    summary.setLayoutParams(summaryLayoutParams);

    return view;
}

}

This method worked for me:

        @Override
public View onCreateView(View parent, String name, Context context, AttributeSet attrs)
{
    View v = super.onCreateView(parent, name, context, attrs);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1)
    {
        if(parent != null)
            parent.setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
        if(v != null)
            v.setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
    }
    return v;
}
