Small Tabs appear using android.support.design.widget.TabLayout -

-

i'm trying create multiple tabs fragment each tab. have managed 2 tabs appear @ corner of layout. i'm unable divide width of tab layout equally tabs. code : activity_main.xml

    <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:app="http://schemas.android.com/apk/res-auto" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingleft="@dimen/activity_horizontal_margin" android:paddingright="@dimen/activity_horizontal_margin" android:paddingtop="@dimen/activity_vertical_margin" android:paddingbottom="@dimen/activity_vertical_margin" tools:context=".mainactivity" android:id="@+id/mainlayout">  <android.support.design.widget.tablayout     android:id="@+id/sliding_tabs"     style = "mycustomtablayout"     android:layout_width="match_parent"     android:layout_height="wrap_content"     app:tabmode="scrollable"     />  <android.support.v4.view.viewpager     android:id="@+id/viewpager"     android:layout_width="match_parent"     android:layout_height="0px"     android:layout_weight="1"     android:background="@android:color/white" /> </linearlayout>

code : fragmentpageradapter

    public class frag_adapter extends fragmentpageradapter { final int page_count =2; private string tabtitles[] = new string[] { "tab1", "tab2", "tab3" }; private context ccontext;  public frag_adapter(fragmentmanager fm) {     super(fm);  }  @override public int getcount() {     return page_count; }  @override public android.support.v4.app.fragment getitem(int i) {     switch (i) {         case 0: return new myfrag();         case 1: return new myfrag1();         default: return null;     } }  @override public charsequence getpagetitle(int position) {     // generate title based on item position     return tabtitles[position]; }

}

add app:tabgravity="fill" tablayout xml if want distribute available space each tab.

change app:tabmode="scrollable" in tablayout xml app:tabmode="fixed" if want tabs shown.
