Android Change Default Direction Swipe Of Viewpager

by default ViewPager swipe direction is left to right to view other tabs with content, now i like to change this direction to right to left. my FragmentPagerAdapter class : public

Solution 1:

ViewPager.setCurrentItem(int pageIndex, boolean isSmoothScroll);

pageIndex is total page count. by doing this user will be forced to swipe from right to left.

Solution 2:

Copy-pasted answer from here

I faced the same problem month ago but I think I found a great solution.

1) Change your TabLayout direction to ltr in xml:

<android.support.design.widget.TabLayout
    android:id="@+id/tl_activity_main"
    android:layout_below="@id/toolbar_activity_main"
    android:layoutDirection="ltr"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    style="@style/DisionTabLayout" />

2) Create custom adapter for ViewPager and override methods getItem(int position) and getPageTitle(int position):

@Overridepublic Fragment getItem(int position) {
    if (mIsRtlOrientation && mTabs != null && mTabs.length > 0) {
        return mTabs[mTabs.length - position - 1].getFragment();
    } else {
        return mTabs[position].getFragment();
    }
}

@OverridepublicintgetCount() {
    return mTabs.length;
}

@Overridepublic CharSequence getPageTitle(int position) {
    if (mIsRtlOrientation && mTabs != null && mTabs.length > 0) {
        return mTabs[mTabs.length - position - 1].getTitle();
    } else {
        return mTabs[position].getTitle();
    }
}

3) Set the adapter to ViewPager and then apply this ViewPager to TabLayout.

privatevoidsetAdapters() {
    // initialize adapter
    mTabsAdapter = new TabsAdapter(getSupportFragmentManager(), mTabs, true);
    // set adapter to ViewPager
    vp.setAdapter(mTabsAdapter);
    // set ViewPager to TabLayout
    tl.setupWithViewPager(vp);
    // if RTL orientation, go to last item
    vp.setCurrentItem(vp.getAdapter().getCount() - 1, false);
}
