Add image on 3 tabs

Question

How can I add images into tab ? Currently I'm able to move the tab to bottom but have no idea on how to change the LL Tab1, LL Tab2, LL Tab3 to icon.Am I on the right path ? Any help would be greatly appreciated.

Anyone can help? Thanks a lot !

Try using TabLayout from Android Design Support Library to meet material design guidelines for tabs.

The Design library’s TabLayout implements both fixed tabs, where the view’s width is divided equally between all of the tabs, as well as scrollable tabs, where the tabs are not a uniform size and can scroll horizontally.

To implement TabLayout check this guide and how to add the icon for swipeable tabs to set icons to tabs using setIcon.

final int[] ICONS = new int[]{
        R.drawable.ic_action_document,
        R.drawable.ic_action_tick,
        R.drawable.ic_action_trash};
        ....
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);

tabLayout.getTabAt(0).setIcon(ICONS[0]);
tabLayout.getTabAt(1).setIcon(ICONS[1]);
tabLayout.getTabAt(2).setIcon(ICONS[2]);

To set the tabs at the bottom in a TabLayout check - How can I set tabs at the bottom and also hide top actionbar? where you put the TabLayout in a relativeLayout and align it to parent bottom:

<android.support.design.widget.TabLayout
    android:id="@+id/tab_layout"
    app:tabMode="fixed"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimary"
    android:elevation="6dp"
    app:tabTextColor="#d3d3d3"
    app:tabSelectedTextColor="#ffffff"
    app:tabIndicatorColor="#ff00ff"
    android:minHeight="?attr/actionBarSize"
    android:layout_alignParentBottom="true"
    />

Although you can put your tab layout at the bottom, try not to use bottom tab bars if possible as per the Pure Android guide.

Other platforms use the bottom tab bar to switch between the app's views. Per platform convention, Android's tabs for view control are shown in action bars at the top of the screen instead.

You can create third fragment class, and layout as i have done above.

Run it. Hope this would work

Answer 3

Try this,

puth this activity_main.xml and set the custom height to TabLayout.

<android.support.design.widget.TabLayout
       android:id="@+id/tabs"
       android:layout_width="match_parent"
       android:layout_height="@dimen/custom_tab_layout_height"
       app:tabMode="fixed"
       app:tabGravity="fill"/>

Create an xml layout named custom_tab.xml under res ⇒ layout. In this layout we have defined the custom view for the tab.

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/tab"
android:textColor="@color/colorAccent"
android:textSize="@dimen/tab_label"
android:fontFamily="@string/font_fontFamily_medium"/>

Open MainActivity.java and modify the code as below. Here if you observe setupTabIcons() method, I have rendered custom_tab.xml layout in each tab using below lines of code.

TextView tabOne = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
tabOne.setText("ONE");
tabOne.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_tab_favourite, 0, 0);
tabLayout.getTabAt(0).setCustomView(tabOne);

TextView tabTwo = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
tabTwo.setText("TWO");
tabTwo.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_tab_call, 0, 0);
tabLayout.getTabAt(1).setCustomView(tabTwo);

TextView tabThree = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
tabThree.setText("THREE");
tabThree.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_tab_contacts, 0, 0);
tabLayout.getTabAt(2).setCustomView(tabThree);
