隐藏我想要一个工具栏+ FrameLyout(片段)虽然滚动片段工具栏应该能在android系统
里面的FrameLayout(TabLayout +查看传呼机)
我已经添加了什么我已经尝试了代码。请看下面的代码是我曾尝试或给一些备用的想法对于这种情况
MainActivity.java
public class MainActivity extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FragmentManager fragmentManager = getSupportFragmentManager();
BlankFragment mSlidingTabsHomeFragment = new BlankFragment();
fragmentManager.beginTransaction()
.replace(R.id.Container, mSlidingTabsHomeFragment)
.commit();
}
}
activity_main.xml中
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/coordinatorLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<!-- AppBar Layout -->
<android.support.design.widget.AppBarLayout
android:id="@+id/appBarLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="fill_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/Container" >
</FrameLayout>
</android.support.design.widget.CoordinatorLayout>
BlankFragment.java
public class BlankFragment extends Fragment {
public BlankFragment() {
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_blank, container, false);
ViewPager viewPager = (ViewPager)view. findViewById(R.id.viewpager);
if (viewPager != null) {
setupViewPager(viewPager);
}
TabLayout tabLayout = (TabLayout) view.findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
return view;
}
private void setupViewPager(ViewPager viewPager) {
Adapter adapter = new Adapter(getActivity().getSupportFragmentManager());
adapter.addFragment(new CheeseListFragment(), "Category 1");
adapter.addFragment(new CheeseListFragment(), "Category 2");
adapter.addFragment(new CheeseListFragment(), "Category 3");
viewPager.setAdapter(adapter);
}
@Override
public void onAttach(Context context) {
super.onAttach(context);
}
static class Adapter extends FragmentPagerAdapter {
private final List<Fragment> mFragments = new ArrayList<>();
private final List<String> mFragmentTitles = new ArrayList<>();
public Adapter(FragmentManager fm) {
super(fm);
}
public void addFragment(Fragment fragment, String title) {
mFragments.add(fragment);
mFragmentTitles.add(title);
}
@Override
public Fragment getItem(int position) {
return mFragments.get(position);
}
@Override
public int getCount() {
return mFragments.size();
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitles.get(position);
}
}
fragment_blank.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/main_content"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</LinearLayout>
是有必要让你有一个framelayout并在Fragment中显示viewpager?为什么你不能把viewpager放在活动 –
的主布局中,因为我必须重构现有的代码 – Deva
,在viewpager中更改页面或垂直滚动片段时,必须隐藏工具栏。 –
