Expected Tabs:

But coming Like:

Coming Tabs

On page Load tabs are coming like "Expected Tabs" image but after selection coming like "Coming Tabs" image. MainXML code:

 <android.support.design.widget.TabLayout                 android:id="@+id/tabs"                 style="@style/MyCustomTabLayout"                 android:layout_width="match_parent"                 android:layout_height="wrap_content"                 android:background="@drawable/background_img_jpeg"                 android:minHeight="10dp"                 android:padding="10dp"                 app:tabGravity="fill"                 app:tabIndicatorColor="@color/TRANSPARENT"                 app:tabMode="fixed"                 app:tabTextColor="@color/blue" /> 

@style/MyCustomTabLayout

<style name="MyCustomTabLayout" parent="Widget.Design.TabLayout">         <item name="tabBackground">@drawable/tab_bg</item>     </style> 

@drawable/tab_bg

<selector xmlns:android="http://schemas.android.com/apk/res/android">     <item android:state_selected="true"         android:drawable="@drawable/tab_bgselected" />     <item android:drawable="@drawable/tab_bgnotselected" />     </selector> 

@drawable/tab_bgselected

<?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android">      <item android:bottom="0dp"  android:top="0dp"           android:left="0dp" android:right="0dp" >         <shape android:shape="rectangle">             <solid android:color="@color/blue" />             <corners                 android:topLeftRadius="10dp"                 android:bottomLeftRadius="10dp">             </corners>         </shape>     </item> </layer-list> 

Like that @drawable/tab_bgnotselected

And in code behind i have written:

tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {             @Override             public void onTabSelected(TabLayout.Tab tab) {                 try {                     mViewPager.setCurrentItem(tab.getPosition());                     TabPosition = tab.getPosition();                     TabCount = tabLayout.getTabCount();                      try {                         if (TabPosition == 0) {                             GradientDrawable drawable = (GradientDrawable) getResources().getDrawable(R.drawable.policy_tab_blue);                             drawable.setCornerRadii(new float[]{10,10,0,0,0,0,10,10}); // this will create the corner radious to left side                          } else {                             GradientDrawable drawable = (GradientDrawable) getResources().getDrawable(R.drawable.policy_tab_white);                             drawable.setCornerRadii(new float[]{0,0,10,10,10,10,0,0}); // this will create the corner radious to right side                          }                     } catch (Exception e) {                         e.printStackTrace();                     }                     Log.i("TabPosition:--->", TabPosition + "");                     Log.i("TabCount:--->", TabCount + "");                  } catch (Exception e) {                     e.printStackTrace();                 }             }              @Override             public void onTabUnselected(TabLayout.Tab tab) {                 try {                  } catch (Exception e) {                     e.printStackTrace();                 }             }              @Override             public void onTabReselected(TabLayout.Tab tab) {              }         });

You can use MaterialCardView with appropriate cardCornerRadius as a parent layout of TabLayout to achieve this one side rounded corner background. Then you can use tabIndicatorColor to colorize the tab selected layout. Hope this will help you. Thanks

Code Snippet:

<com.google.android.material.card.MaterialCardView     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:layout_margin="10dp"     app:strokeWidth="2dp"     app:strokeColor="?attr/colorAccent"     app:cardCornerRadius="20dp">     <com.google.android.material.tabs.TabLayout         app:tabTextAppearance="@android:style/TextAppearance.Widget.TabWidget"         android:id="@+id/tab_layout"         app:tabIndicatorGravity="stretch"         app:tabMaxWidth="0dp"         app:tabGravity="fill"         app:tabMode="fixed"         app:tabIndicatorColor="?attr/colorAccent"         app:tabSelectedTextColor="@android:color/white"         app:tabTextColor="?attr/colorPrimary"         android:layout_width="match_parent"         android:layout_height="35dp"/> </com.google.android.material.card.MaterialCardView>
