un-material-tab library

A customizable alternative of TabLayout from Support Design library which provides almost the same functionality.

Currently working on

• RoundTabLayout#onTabSelected & RoundTabLayout#onTabReselected callbacks
• reducing number of GPU view updates
• new tab animations

If you have any suggestions - feel free to open an issue.

How to add?

I. In your build.gradle file add the following dependency:

dependencies {

  compile 'com.ruslankishai:unmaterialtabs:0.1a' 
}
 

II. Declare RoundTabLayout inside your layout.xml file:

<com.ruslankishai.unmaterialtab.tabs.RoundTabLayout

 android:id="@+id/round_tabs"

 android:layout_width="match_parent"

 android:layout_height="wrap_content"

 android:background="@color/colorPrimary"

 app:accent="@color/colorAccent" />

III. Declare RoundTabLayout with ViewPager in your 'class.java':

ViewPager viewPager = (ViewPager) findViewById(R.id.viewPager);
  //set adapter to your ViewPager ViewPager.setAdapter(new TabPagerAdapter(getFragmentManager()));
  RoundTabLayout tabLayout = (RoundTabLayout) findViewById(R.id.roundTabLayout);
 tabLayout.setupWithViewPager(viewPager);

IV. Override you getPageTitle method in your ViewPager’s adapter to return tab title.

@Override public CharSequence getPageTitle(int position) {

  switch (position) {

  case 0:

 return "First item";

  ...

}
 
}

How to customize?

I. In your layout.xml file you can set a few attributes to RoundedTabLayout:

• android:background
  • This attribute works just like usual background attribute (reference to a color).
• app:accent
  • This attribute allows you to set accent color for tab selection, stroke and text (reference to a color).
• app:cornerRadius
  • This attribute sets the tab corner radius. Possible values are:
    • circle (default)
    • rounded
    • rectangle
    • value in px from 0 to 50

II. In your class.java you can set some values to customize specific tab:

• Use RoundTab#setIcon method to change icon. You can get RoundTab object via RoundTabLayout#getTab method which accept tab index as parameter. To enable tab icon, you should also use RoundTab#setHasIcon.

… //after initializing RoundTabLayout and ViewPager RoundTab tab = tabLayout.getTab(0);
 Drawable icon = getResources().getDrawable(R.drawable.globe);
 tab.setIcon(icon);
 //enable icon in current tab tab.setHasIcon(true);
  //repeat this code for another tabs …

• To disable tab stroke use RoundTab#setHasStroke method.

… //after initializing RoundTabLayout and ViewPager RoundTab tab = tabLayout.getTab(0);
 tab.setHasStroke(true);
 …

• To change corners radius use RoundTab#setCornerRadius which accept values from 0 to 50 as a parameter.

… //after initializing RoundTabLayout and ViewPager RoundTab tab = tabLayout.getTab(0);
 tab.setCornerRadius(35);
 …

• To change tab text use RoundTab#setText which accept String as a parameter.

… //after initializing RoundTabLayout and ViewPager RoundTab tab = tabLayout.getTab(0);
 tab.setText(“Usage example”);
 …

Where is un-material-tab demo app?

The app works just as an example of usage with different options. Will be uploaded to Play Store sooner.

What about contributions?

This is my first public repo and first library so I’m trying to keep this code as much clean and well-commented as I can. Feel free to contribute :)
