如何实现TabLayout
,其中选项卡从左或从右开始,但从中心开始不正确。TabLayout
具有属性app:tabGravity="center"
,但是如何在特定位置向左或向右排列选项卡?
非常感谢。
最佳答案
下面为我工作。
标签将显示在左侧。
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginStart="2dp"
android:layout_marginTop="2dp"
app:layout_scrollFlags="scroll|enterAlways|snap">
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="0dp"
android:background="?attr/colorPrimary"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
app:tabGravity="fill"
app:tabMode="scrollable"
app:tabPaddingEnd="10dp"
app:tabPaddingStart="20dp" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</RelativeLayout>
MainActivity.java
public class MainActivity extends AppCompatActivity {
//This is our tablayout
private TabLayout tabLayout;
//This is our viewPager
private ViewPager viewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tabLayout = findViewById(R.id.tabs);
viewPager = findViewById(R.id.view_pager);
tabLayout.addTab(tabLayout.newTab().setText("Tab1"));
// tabLayout.addTab(tabLayout.newTab().setText("Tab2"));
// tabLayout.addTab(tabLayout.newTab().setText("tab3"));
Pager adapter = new Pager(getSupportFragmentManager(), tabLayout.getTabCount());
viewPager.setAdapter(adapter);
}
