Navigation drawer starts from right side

问题

How can i make the navigation drawer open from the right to the left?

Main.xml

<android.support.design.widget.NavigationView
    android:id="@+id/navigation_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="end"
    app:headerLayout="@layout/drawer_header"
    app:menu="@menu/navigation"
    android:background="#FFE7FF"/>

drawer_header.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="150dp"
android:baselineAligned="false"
android:orientation="vertical">

navigation.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<group android:checkableBehavior="single">
    <item
        android:id="@+id/Home"
        android:checked="true"
        android:icon="@drawable/homelogo"
        android:title="Home" /></group></menu>

This is how i create it in main activity

navigationView = (NavigationView) findViewById(R.id.navigation_view);
    navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(MenuItem menuItem) {
            switch (menuItem.getItemId()) {
              (..........)

How can i make it ? I've tried android:gravity but it doesn't work.

回答1:

In your main.xml there is the android.support.design.widget.NavigationView which has the following attribute: android:layout_gravity="end". You have to set it to right, so it will be like this: android:layout_gravity="right". The rest is done by the design support lib.

Note that the Android Studio will show a warning that you should use end instead of right in order to ensure correct behavior in right-to-left languages. You can ignore this message.

Try setting android:layout_gravity="end" instead of android:layout_gravity="start"

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="end"
    android:fitsSystemWindows="true"
    app:headerLayout="@layout/nav_header_main"
    app:menu="@menu/activity_main_drawer" />

it does change , only two things to do ,

After addig a new activity to your android app from android studio->file->new->activity ->Navigation Draw....

you have to change android:layout_gravity="right" in main layout's android.support.design.widget.NavigationView and drawer.closeDrawer(GravityCompat.END); in your OnNavigationItemSelected() function in main activity .
