Tab with icon using TabLayout in Android Design Li

问题:

I'm trying to use the new TabLayout in the android design library to create app bar with icons only.

like this:

how can I do it using the new TabLayout Android Design Library.

is there a simple solution for this, or i have to use the setCustomView only. i'm trying to avoid using it. because i didn't get the tint color for the icon like this image above.

i try to write like this:

tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.ic_dashboard))

but the icon still stay in the same color when i select the tab

回答1:

you have to create a selector for the icon. For example:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ic_dashboard_pressed"
          android:state_pressed="true" />
    <item android:drawable="@drawable/ic_dashboard_selected"
          android:state_selected="true" />
    <item android:drawable="@drawable/ic_dashboard_normal" />
</selector>

I used it like this: created an xml file in drawable as shown by @Budius.

in the code: tabLayout.getTabAt(0).setIcon(R.drawable.settings_tab_drawable);

and so on.

i solved it like this:

tint_tab.xml

<com.hannesdorfmann.appkit.image.TintableImageView
 xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:app="http://schemas.android.com/apk/res-auto"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 app:tint="@color/tab_color_selector"/>

in you java code

TintableImageView tab1 = (TintableImageView) LayoutInflater.from(this).inflate(R.layout.tint_tab, null);
tab1.setImageResource(R.drawable.ic_dummy);
mTabLayout.getTabAt(0).setCustomView(tab1)
