[英]How To Add Tabbed Activity Into Navigation Drawer Activity?
在導航抽屜活動中,更改您的布局,如下所示:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical"
tools:context="in.net.spectrum.citytour.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
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:popupTheme="@style/AppTheme.PopupOverlay" />
//
//
// Tab layout to show tabs
//
//
<android.support.design.widget.TabLayout
android:background="@color/colorPrimary"
app:tabSelectedTextColor="#ffffff"
app:tabIndicatorColor="#FFFFFF"
app:tabIndicatorHeight="3dp"
app:tabTextColor="#FFFFFF"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabGravity="fill"
android:id="@+id/tbl_pages"/>
</android.support.design.widget.AppBarLayout>
<!-- <include layout="@layout/content_main" />-->
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
//
//
//ViewPager to show tab's fragments
//
//
<android.support.v4.view.ViewPager
android:id="@+id/vp_pages"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="@dimen/fab_margin"
app:srcCompat="@android:drawable/ic_dialog_email" />
</FrameLayout>
</LinearLayout>
現在在onCreate()里面的Activity Java代碼中添加以下行:
@Override
protected void onCreate(Bundle savedInstanceState) {
.
.
.
.
ViewPager vp_pages= (ViewPager) findViewById(R.id.vp_pages);
PagerAdapter pagerAdapter=new FragmentAdapter(getSupportFragmentManager());
vp_pages.setAdapter(pagerAdapter);
TabLayout tbl_pages= (TabLayout) findViewById(R.id.tbl_pages);
tbl_pages.setupWithViewPager(vp_pages);
}
現在在onCreate()方法之外創建片段適配器:
class FragmentAdapter extends FragmentPagerAdapter {
public FragmentAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
switch (position){
case 0:
return new YourFragment1();
case 1:
return new YourFragment2();
case 2:
return new YourFragment3();
}
return null;
}
@Override
public int getCount() {
return 3;
}
@Override
public CharSequence getPageTitle(int position) {
switch (position){
//
//Your tab titles
//
case 0:return "Profile";
case 1:return "Search";
case 2: return "Contacts";
default:return null;
}
}
}
干杯,快樂的編碼。
