How to make support.v4.widget.SlidingPaneLayout pane slide towards left

Question

I'm using support.v4.widget.SlidingPaneLayout, My app supports two languages, English and Arabic. Android version supported is from 4.2.

For English I'm using default behaviour of SlidingPaneLayout ie. menu will be at the left and the content frame opens from left to right. When User selects arabic language. I want everything to be from Right to Left (RTL).

Please tell me any tweek to the SlidingPaneLayout such that in 1 shot I can make it RTL ie. menu on the right Side and content frame opens from right to left.

Thanks in advance.

Answer 1

First add RTL support

In order to support RTL in your app, you first need to add android:supportsRtl="true" to the <application> element in your manifest file.

Set LTR in SlidingPanLayout

Add in SlidingPaneLayout

• android:layoutDirection="ltr" for left
• android:layoutDirection="locale" determinate by system

Sample: set SlidingPanelLayout in left

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SlidingPaneLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/sliding_panel"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    android:layoutDirection="ltr"
    tools:context=".MainActivity"
    tools:showIn="@layout/app_bar_main">

    <fragment
        android:id="@+id/panel_left"
        android:name="onePanelFragment"
        android:layout_width="180dp"
        android:layout_height="match_parent"
        android:layout_gravity="start" />

    <fragment
        android:id="@+id/panel_right"
        android:name="twoPanelFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="end"
        android:layout_weight="1" />

</android.support.v4.widget.SlidingPaneLayout>

remember that the components inside the SliderLayout will also affect their alignment
