问题描述
这是我在主要活动中的代码
This is my code in the main activity
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); } }这是我在XML中的代码
And this is my code in the XML
<LinearLayout xmlns:android="schemas.android/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>我想更改一个选项卡的背景色
I want to change the background color of one tab when it's selected
推荐答案最终对我有用的方法与@如果我是DJ建议的类似,但tabBackground应该位于layout文件中,并且不是 ,因此它看起来像:
What finally worked for me is similar to what @如果我是DJ suggested, but the tabBackground should be in the layout file and not inside the style, so it looks like:
res/layout/somefile.xml :
res/layout/somefile.xml:
<android.support.design.widget.TabLayout .... app:tabBackground="@drawable/tab_color_selector" ... />和选择器 res/drawable/tab_color_selector.xml :
and the selector res/drawable/tab_color_selector.xml:
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="schemas.android/apk/res/android"> <item android:drawable="@color/tab_background_selected" android:state_selected="true"/> <item android:drawable="@color/tab_background_unselected"/> </selector>更多推荐
