根据Michael De Soto的指导(请参阅上面的评论),我可以通过使用具有
这是我如何实现它的家伙
我的活动 xml
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:id="@+id/mainActivityBar"
android:layout_alignParentTop="true"
android:background="@drawable/actionbar"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
app:contentInsetEnd="0dp"
app:contentInsetRight="0dp"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="President"
android:id="@+id/appname_1"
android:background="@android:color/transparent"
android:textColor="#ffffff"
android:layout_marginLeft="20dp" />
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
style="@style/myCustomTabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@android:color/transparent"
android:layout_below="@+id/appname_1"
android:layout_alignParentEnd="true"
android:layout_alignParentStart="false"
android:layout_alignParentLeft="false"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="false"
android:layout_alignLeft="@+id/appname_1"
app:tabGravity="fill"
app:tabMode="scrollable"/>
</RelativeLayout>
</android.support.v7.widget.Toolbar>
在我的styles.xml 中添加了以下内容
<style name="mainActivityTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
<item name="android:textColorSecondary">@android:color/white</item>
<!--We will be using the toolbar so no need to show ActionBar-->
<item name="android:windowActionBar">false</item>
</style>
<style name="myCustomTabLayout" parent="Widget.Design.TabLayout">
<item name="tabIndicatorColor">?attr/colorAccent</item>
<item name="tabIndicatorHeight">2dp</item>
<item name="tabSelectedTextColor">?android:textColorPrimary</item>
</style>
最后,我的活动
public class MainActivity extends AppCompatActivity {
private SectionsPagerAdapter mSectionsPagerAdapter;
TabLayout tabLayout;
private ViewPager mViewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar =(Toolbar) findViewById(R.id.mainActivityBar);
setSupportActionBar(toolbar);
tabLayout = (TabLayout) findViewById(R.id.tabs);
// 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.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setupWithViewPager(mViewPager);
}
public class SectionsPagerAdapter extends FragmentStatePagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
// getItem is called to instantiate the fragment for the given page.
switch (position) {
case 0:
return Item1fragment.newInstance();
case 1:
return Item2fragment.newInstance();
case 2:
return Item3fragment.newInstance();
}
return null;
}
@Override
public int getCount() {
// Show 3 total pages.
return 3;
}
@Override
public CharSequence getPageTitle(int position) {
Locale l = Locale.getDefault();
switch (position) {
case 0:
return "Item1;
case 1:
return "Item2";
case 2:
return "Item3";
}
return "";
}
}
}
