TabLayout을 사용할 때 탭 배경색을 어떻게 변경합니까?

---

이것은 주요 활동의 내 코드입니다.

public class FilterActivity extends AppCompatActivity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_filter);

    // Get the ViewPager and set it's PagerAdapter so that it can display items
    ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);
    PageAdapter pageAdapter = new PageAdapter(getSupportFragmentManager(), FilterActivity.this);
    viewPager.setAdapter(pageAdapter);

    // Give the TabLayout the ViewPager
    final TabLayout tabLayout = (TabLayout) findViewById(R.id.sliding_tabs);
    tabLayout.setupWithViewPager(viewPager);



  }
}

그리고 이것은 XML의 내 코드입니다.

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

    <include
        android:id="@+id/app_bar"
        layout="@layout/app_bar">
    </include>

    <android.support.design.widget.TabLayout
        android:id="@+id/sliding_tabs"
        android:layout_width="fill_parent"
        style="@style/MyCustomTabLayout"
        android:layout_height="48dp"/>

    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="0px"
        android:layout_weight="1"
        android:background="@android:color/white" />

</LinearLayout>

한 탭을 선택하면 배경색을 변경하고 싶습니다.

무엇 결국 나를 위해 일한 것은 @가如果我是DJ 제안 것과 유사하지만이 tabBackground에 있어야 layout파일을 하지 내부 style가 보이는, 그래서 :

res/layout/somefile.xml:

<android.support.design.widget.TabLayout
    ....
    app:tabBackground="@drawable/tab_color_selector"
    ...
    />

및 선택기 res/drawable/tab_color_selector.xml:

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

---

이것을 시도 할 수 있습니다.

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

백그라운드 xml 파일에서 :

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

---

xml에 속성을 추가합니다.

<android.support.design.widget.TabLayout
    ....
    app:tabBackground="@drawable/tab_color_selector"
    ...
    />

그리고 드로어 블 폴더 tab_color_selector.xml에 생성합니다.

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

API를 확인해 보셨습니까 ?

You will need to create a listener for the OnTabSelectedListener event, then when a user selects any tab you should check if it is the correct one, then change the background color using tabLayout.setBackgroundColor(int color), or if it is not the correct tab make sure you change back to the normal color again with the same method.

You can have it in the xml.

<android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        app:tabTextColor="@color/colorGray"
        app:tabSelectedTextColor="@color/colorWhite"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

As I found best and suitable option for me and it will work with animation too.

You can use indicator it self as a background.

You can set app:tabIndicatorGravity="stretch" attribute to use as background.

Example:

   <android.support.design.widget.TabLayout
        android:id="@+id/tab_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabIndicatorGravity="stretch"
        app:tabSelectedTextColor="@color/white"
        app:tabTextColor="@color/colorAccent">

        <android.support.design.widget.TabItem
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Chef" />


        <android.support.design.widget.TabItem
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="User" />

    </android.support.design.widget.TabLayout>

Hope it will helps you.

You can change the background color of the tab by this attribute

<android.support.design.widget.TabLayout
android:id="@+id/tabs"
style="@style/CategoryTab"
android:layout_width="match_parent"
android:layout_height="wrap_content"
'android:background="@color/primary_color"/>'

---

You can change the background or ripple color of each Tab like this:

    //set ripple color for each tab
    for(int n = 0; n < mTabLayout.getTabCount(); n++){

        View tab = ((ViewGroup)mTabLayout.getChildAt(0)).getChildAt(n);

        if(tab != null && tab.getBackground() instanceof RippleDrawable){
            RippleDrawable rippleDrawable = (RippleDrawable)tab.getBackground();
            if (rippleDrawable != null) {
                rippleDrawable.setColor(ColorStateList.valueOf(rippleColor));
            }
        }
    }

One of simplest solution is to change colorPrimary from colors.xml file.
