使用TabsLayout实现了一个标签式活动,但现在活动的标题没有显示在工具栏上,尝试了我在互联网上找到的各种修复,但似乎都没有。
活动的xml:
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:title="title"
android:paddingTop="@dimen/appbar_padding_top"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/AppTheme.PopupOverlay">
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="@dimen/appbar_padding_top"
android:theme="@style/AppTheme.AppBarOverlay"
app:tabMode="scrollable">
</android.support.design.widget.TabLayout>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
OnCreate中: protected void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); 的setContentView(R.layout.activity_ordenes_de_viaje_tabbed);
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
// Give the TabLayout the ViewPager
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
Intent intent = getIntent();
item = intent.getIntExtra("item", 0);
mViewPager.setCurrentItem(item);
Toolbar mActionBarToolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(mActionBarToolbar);
setSupportActionBar(mActionBarToolbar);
getSupportActionBar().setTitle("My title");
getSupportActionBar().setDisplayShowTitleEnabled(true);
答案 0 :(得分:2)
你的tabLayout不应该是你的工具栏的子项,它应该在它下面,而用户?attr / actionBarSize女巫会给你准确的操作栏大小,无论设备dpi
