Like putting icon and text in tabs (Sliding Tabs)

问题:

I need to make my application with this appearance (icon and text): https://material-design.storage.googleapis.com/publish/material_v_4/material_ext_publish/0B6Okdz75tqQsbHJuWi04N0ZIc0E/components_tabs_usage_mobile7.png

But so far I can only leave it like this: http://i.imgur.com/npz0eRJ.png

How can I fix this?

Follow my xml tabs:

<LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android"
    android: layout_width = "match_parent"
    android: layout_height = "match_parent"
    android: gravity = "center">

        <ImageView
            android: id = "@ + id / imgTab"
            android: layout_width = "wrap_content"
            android: layout_height = "wrap_content"
            />

        <TextView
            android: TEXTSIZE = "14sp"
            android: textColor = "@ android: color / white"
            android: id = "@ + id / tv_tab"
            android: layout_width = "wrap_content"
            android: layout_height = "wrap_content" />


</ LinearLayout>

Method in the fragment (Tab):

public CharSequence getPageTitle (int position) {

    Drawable tab = mContext.getResources () getDrawable (icons [position]).;
            tab.setBounds (0, 0, heightIcon, heightIcon);



            ImageSpan ImageSpan is = new (tab);
            SpannableString sp = new SpannableString (titles [position]);
            sp.setSpan (s, sp.length () - 1, sp.length (), 0);

            return sp;

I tried to follow Need to center-align a single portion of text in a TextView but it did not work for me :(

Can anyone help me please?

See my answer Here and follow it properly.

A little change here will do the trick:

 Drawable image = getActivity().getResources().getDrawable(R.drawable.ic_launcher);
 image.setBounds(0, 0, image.getIntrinsicWidth(), image.getIntrinsicHeight());
 SpannableString sb = new SpannableString(" \n"+"hello");
 ImageSpan imageSpan = new ImageSpan(image, ImageSpan.ALIGN_BOTTOM);
 sb.setSpan(imageSpan, 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 return sb;

in place of the "hello" use your title.

Hope it will help.

You can achieve your task with the following very easily. Firstly create new XML under Layout Folder. Give it name [custom_tab_view] then paste the below code.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ripple="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@drawable/custom_bg"
    android:padding="8dp">

    <!--<com.andexert.library.RippleView
        android:id="@+id/more"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        ripple:rv_centered="true">-->

        <ImageView
            android:id="@+id/tabImage"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

        <TextView
            android:id="@+id/tabText"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="bottom|center" />


</LinearLayout>

And now went to your ViewPageAdapter and Replace your Function [CharSequence] with below code.

 // This method return the titles for the Tabs in the Tab Strip
    @Override
    public CharSequence getPageTitle(int position) {
        //return Titles[position];
        Drawable image = mContext.getResources().getDrawable(imageResId[position]);
        image.setBounds(0, 0, image.getIntrinsicWidth(), image.getIntrinsicHeight());
        //image.setBounds(0, 0, 64, 64);
        ImageSpan imageSpan = new ImageSpan(image, ImageSpan.ALIGN_BOTTOM);
        SpannableString sb = new SpannableString(" ");
        sb.setSpan(imageSpan, 0, sb.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);


        return sb;
    }

and in the MainActivity under OnCreate put this line if it is not already there.

SlidingTabLayout tabs;
tabs.setCustomTabView(R.layout.custom_tab_view, R.id.tabText);


                                                 Hope it answer the Question.

Using the default Tabbed Activity from android studio, just add the following:

TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);

tabLayout.getTabAt(0).setIcon(R.drawable.image_1);
tabLayout.getTabAt(1).setIcon(R.drawable.image_2);
tabLayout.getTabAt(2).setIcon(R.drawable.image_3);
