i am working on a android project where i have to implement collapsing toolbar with tabs . Tabs should contain a normal Relative layout which has 4 textview.
I am successfully able to implement the collapsing toolbar but the problem is when ever i try to scroll upwards holding the tabs i have implemented collapse toolbar is not working. On the same tabs if i use a list view or Grid layout its working fine when i scroll. If i try to use Normal layout's such as Linear or Relative layout i am not able to scroll. is there any way i can fix this without list or grid layout?
below is my code for xml:
<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/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
style="@style/MyStyle"
android:layout_width="match_parent"
app:tabIndicatorColor="#F21757"
app:tabSelectedTextColor="#F21757"
android:layout_height="?actionBarSize"
app:tabTextColor="@android:color/white"
app:layout_anchor="@+id/MyAppbar"
app:layout_anchorGravity="bottom"
android:layout_gravity="bottom"
app:tabGravity="fill"
app:tabMode="scrollable"
android:background="#171C20" />
<android.support.design.widget.AppBarLayout
android:id="@+id/MyAppbar"
android:layout_width="match_parent"
android:layout_height="256dp"
android:fitsSystemWindows="true"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
>
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/collapse_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:contentScrim="#000000"
android:fitsSystemWindows="true">
<ImageView
android:id="@+id/bgheader"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:src="@drawable/load"
android:fitsSystemWindows="true"
app:layout_collapseMode="parallax"
/>
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
app:layout_collapseMode="pin"
/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/viewPager"
android:paddingBottom="20dp"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
Try this
Step 1. main_activity.xml
<android.support.design.widget.CoordinatorLayout 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:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.ncrypted.demoapplications.MainActivity">
<android.support.design.widget.AppBarLayout
android:id="@+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/collapsingToolBar_hotel_details"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="@+id/img_hotel_details"
android:layout_width="match_parent"
android:layout_height="300dp"
android:contentDescription="@string/strong_image_of_andorid"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
android:src="@mipmap/ic_launcher"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="@+id/toolBar_hotel_detail"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_collapseMode="pin"
app:tabGravity="fill"
app:tabMode="fixed" />
</android.support.design.widget.AppBarLayout>
<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">
</android.support.v4.view.ViewPager>
Step:2 Create fragments activity
- FragmentActivity1
fragment1.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context="com.ncrypted.demoapplications.FragmentActivity1">
<!-- TODO: Update blank fragment layout -->
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="@string/hello_blank_fragment1" />
FragmentActivity.java
public class FragmentActivity1 extends Fragment {
public FragmentActivity1()
{
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_fragment_activity1, container, false);
}
}
Step:3 take two other Fragment 2,3 and write code as above
Step:4 MainActivity.java
public class MainActivity extends AppCompatActivity {
private ViewPager pager;
private TabLayout tabLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolBar_hotel_detail);
setSupportActionBar(toolbar);
ViewCompat.setTransitionName(findViewById(R.id.app_bar_layout), "Extra Image");
CollapsingToolbarLayout collapsingToolbarLayout = (CollapsingToolbarLayout)
findViewById(R.id.collapsingToolBar_hotel_details); collapsingToolbarLayout.setContentScrimColor(ContextCompat.getColor(getApplicationContext(), R.color.colorPrimary));
collapsingToolbarLayout.setTitle("Collaps");
pager = (ViewPager) findViewById(R.id.viewPager);
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new FragmentActivity1());
adapter.addFragment(new FragmentActivity2());
adapter.addFragment(new FragmentActivity3());
pager.setAdapter(adapter);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(pager);
tabLayout.getTabAt(0).setText("Tab1");
tabLayout.getTabAt(1).setText("Tab2");
tabLayout.getTabAt(2).setText("Tab3");
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
@Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
@Override
public int getCount() {
return mFragmentList.size();
}
public void addFragment(Fragment fragment) {
mFragmentList.add(fragment);
}
}
}
