CollapsingToolbarLayout Menu and Up Indicator - android

I am using the new android design CollapsingToolbarLayout. However, I am unable to get the menu to appear. Also, the homeasup indicator does not appear.
Can someone point me in the right direction? Or is this simply not possible?
EDIT
So, I finally got my laptop back. Here is the code.
The Activity
public class CheeseDetailActivity extends AppCompatActivity {
public static final String EXTRA_NAME = "cheese_name";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_detail);
Intent intent = getIntent();
final String cheeseName = intent.getStringExtra(EXTRA_NAME);
final Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
CollapsingToolbarLayout collapsingToolbar =
(CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
collapsingToolbar.setTitle(cheeseName);
loadBackdrop();
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
finish();
return true;
}
return super.onOptionsItemSelected(item);
}
private void loadBackdrop() {
final ImageView imageView = (ImageView) findViewById(R.id.backdrop);
Glide.with(this).load(Cheeses.getRandomCheeseDrawable()).centerCrop().into(imageView);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_player, menu);
return true;
}
}
The Layout
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

</android.support.design.widget.CoordinatorLayout>
The menu
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto" >
<item android:id="#+id/action_settings" android:title="#string/action_settings"
android:orderInCategory="100" app:showAsAction="ifRoom" />
</menu>
As we can see, there is no overflow, nothing. But when I press the physical menu button, the menu pops up fine.

So, I guess I was really really dumb. I used the wrong margin for the toolbar. android:layout_marginTop="#dimen/toolbar_top_margin"
The margin was supposed to be -48dp, but I was using 48dp.
I had this in my dimens. I forgot to change to toolbar_top_margin_neg after I refactored.
<dimen name="toolbar_top_margin">48dp</dimen>
<dimen name="toolbar_top_margin_neg">-48dp</dimen>

ActionBarDrawerToggle isn't working till the time i manually swipe right to open the navigation drawer. After this, it responds perfectly

Problem:
When I open my application and click on the ActionBarDrawerToggle, it doesn't open the navigation drawer. However, when i swipe right and then open and close the navigation drawer, after this the ActionBarDrawerToggle repsonds perfectly fine, like it should, by opening the drawer.
My HomeScreen.java
public class HomeScreen extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener{
private Toolbar toolbar;
private DrawerLayout drawerLayout;
private NavigationView navigationView;
private ActionBarDrawerToggle toggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home_screen);
instantiateViews();
setSupportActionBar(toolbar);
navigationView.setNavigationItemSelectedListener(this);
toggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.navigation_drawer_open,R.string.navigation_drawer_close);
drawerLayout.addDrawerListener(toggle);
toggle.syncState();
}
public void instantiateViews(){
toolbar = findViewById(R.id.drawer_menu_toolbar);
drawerLayout = findViewById(R.id.home_screen_main_drawer_layout);
navigationView = findViewById(R.id.home_screen_navigation_view);
}
#Override
public void onBackPressed(){
if(drawerLayout.isDrawerOpen(GravityCompat.START)){
drawerLayout.closeDrawer(GravityCompat.START);
}else {
super.onBackPressed();
}
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
switch (menuItem.getItemId()){
case R.id.nav_home:
break;
case R.id.nav_account:
break;
case R.id.nav_share:
break;
case R.id.nav_logout:
session.logoutUser();
break;
}
drawerLayout.closeDrawer(GravityCompat.START);
return true;
}
}
I have tried everything from the following thread: Navigation Drawer ActionBar button not working even though for that person the ActionBarDrawerToggle wasn't working under all circumstances but mine isn't working till the time navigation drawer is opened. After that mine works perfectly
What I have tried doing:
1.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (toggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
2.
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
toggle.syncState();
3.
toggle.setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
drawerLayout.openDrawer(GravityCompat.START);
}
});
None of these work for me

Try this, or Try to take out your Toolbar from Relative Layout.

Floating button between action bar and Frame Layout

I want something like this:
I have the following now:
With the following XML:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="130dp"
android:layout_width="match_parent">

app:contentScrim="?attr/colorPrimary">
<android.support.v7.widget.Toolbar

android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent">

<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/book_detail">
</FrameLayout>
</android.support.v4.widget.NestedScrollView>
<android.support.design.widget.FloatingActionButton
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:src="#android:drawable/ic_input_add"
android:layout_margin="16dp"
android:clickable="true"
android:focusable="true"
app:layout_anchor="#id/appbar"
app:layout_anchorGravity="bottom|end"/>
</android.support.design.widget.CoordinatorLayout>
But I have some problems:
The Title is on top instead of bottom
There's something like a separator on top
I'm using a coordinator now, but I don't need a collapsing toolbar, so I think that there must be another solution maybe. How can I solve this?
Let's first start by making the toolbar taller. I think what you're looking for is CollapingToolbarLayout
To use the CollapsingToolbarLayout you have to change your ConstraintLayout to CoordinatorLayout.
Then you have to create an AppBarLayout to hold the CollapsingToolbarLayout and the Toolbar.
Then to make the floating button in that place you have to anchor it to the AppBarLayout created earlier like below:
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top|end"
android:layout_margin="16dp"
app:layout_anchor="#id/app_bar"
app:layout_anchorGravity="bottom|end"
android:clickable="true"
android:src="#drawable/message"
android:focusable="true"
app:elevation="30dp"/>
That way it will be anchored to the AppBarLayout so it will go up and down as the AppBarLayout goes up or down.
EDIT #1 :
To remove the title from the top and remove the separator you have to set your activity's theme to NoActionBar. In your AndroidManifest.xml file go to your activity and change its code to the following:
<activity
android:name="YOUR_ACTIVITY_PATH.BookDetailActivity"
android:theme="#style/AppTheme.NoActionBar" />
This way the activity will be declared without an action bar which means no separator and no title.
Then to add the title to the bottom you just have to set the title of the CollapsingToolbarLayout to the text you want.
You can set it in the xml with app:title="YOUR_TITLE" attribute or you can set it programmatically by calling the function setTitle("YOUR_TITLE") for your CollapsingToolbarLayout variable .
Here is what the full code could look like:
<?xml version="1.0" encoding="utf-8"?>

</android.support.design.widget.CoordinatorLayout>
EDIT 2:
In your activity set your action bar by this :
setSupportActionBar(YOUR_TOOLBAR_VARIABLE) then you can use getSupportActionBar().setDisplayHomeAsUpEnabled(true)
Note that the toolbar should be the id of this one:
android.support.v7.widget.Toolbar so in our case the toolbar with the id toolbar
Use this layout
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="192dp">
<android.support.design.widget.CollapsingToolbarLayout

android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin" />

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"
app:layout_anchor="#id/app_bar_layout"
app:layout_anchorGravity="bottom|right|end" />
The use this class for action of FAB
public class FlexibleSpaceExampleActivity extends AppCompatActivity
implements AppBarLayout.OnOffsetChangedListener {
private static final int PERCENTAGE_TO_SHOW_IMAGE = 20;
private View mFab;
private int mMaxScrollSize;
private boolean mIsImageHidden;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_flexible_space);
mFab = findViewById(R.id.flexible_example_fab);
Toolbar toolbar = (Toolbar) findViewById(R.id.flexible_example_toolbar);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override public void onClick(View v) {
onBackPressed();
}
});
AppBarLayout appbar = (AppBarLayout) findViewById(R.id.flexible_example_appbar);
appbar.addOnOffsetChangedListener(this);
}
#Override
public void onOffsetChanged(AppBarLayout appBarLayout, int i) {
if (mMaxScrollSize == 0)
mMaxScrollSize = appBarLayout.getTotalScrollRange();
int currentScrollPercentage = (Math.abs(i)) * 100
/ mMaxScrollSize;
if (currentScrollPercentage >= PERCENTAGE_TO_SHOW_IMAGE) {
if (!mIsImageHidden) {
mIsImageHidden = true;
ViewCompat.animate(mFab).scaleY(0).scaleX(0).start();
/**
* Realize your any behavior for FAB here!
**/
}
}
if (currentScrollPercentage < PERCENTAGE_TO_SHOW_IMAGE) {
if (mIsImageHidden) {
mIsImageHidden = false;
ViewCompat.animate(mFab).scaleY(1).scaleX(1).start();
/**
* Realize your any behavior for FAB here!
**/
}
}
}
public static void start(Context c) {
c.startActivity(new Intent(c, FlexibleSpaceExampleActivity.class));
}
}
There are some Github Implementation to develope this view and many other

ViewPager inside ScrollView not working

I want to put a ViewPager inside a CoordinatorLayout withing a NestedScrollView. The viewpager houses 3 fragments.
Problem is the fragments aren't visible. Tabs show up and the rest of the layout is visible and scrolls accordingly.
Below is the code for my layout:

Try adding this piece of code before loading your viewPager
NestedScrollView scrollView = (NestedScrollView) findViewById (R.id.nest_scrollview);
scrollView.setFillViewport (true);
Let me know if it helped fix the issue.
Use android:fillViewport="true" in ScrollView
The accepted answer resulted in my fragments now being visible. However, it left me with the problem that my NestedScrollView would no longer scroll!
To overcome this, I have created a custom ViewPager (based on this article) that calculates it's height in the required manner.
Here is full code for my CustomViewPager:
package org.example;
import android.content.Context;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.View;
public class CustomViewPager extends ViewPager {
public CustomViewPager(#NonNull Context context) {
super(context);
}
public CustomViewPager(#NonNull Context context, #Nullable AttributeSet attrs) {
super(context, attrs);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
try {
int numChildren = getChildCount();
for (int i = 0; i < numChildren; i++) {
View child = getChildAt(i);
if (child != null) {
child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
int h = child.getMeasuredHeight();
heightMeasureSpec = Math.max(heightMeasureSpec, MeasureSpec.makeMeasureSpec(h, MeasureSpec.EXACTLY));
}
}
}
catch (Exception e) {
e.printStackTrace();
}
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
In your layout xml, you'd then just replace android.support.v4.view.ViewPager with org.example.CustomViewPager.
(I also removed the new android:fillViewport="true" attribute from my NestedScrollView element as it seems this is now no longer needed.)
No need to use ScrollView and NestedScroolview Just use SliderLayout it will work perfectly.
add below dependency inside build.gradle (app level)

Use nestedScrollview and set the property of nestedscrollenabled as true and I think you will do it.
So let me do it for you : the correct hierarchy as suggested by google blogspot it is working fine for me:Check this out

Collapsing/Expanding view coordinated with Sliding RecyclerView

I am trying to achieve the following affect (also see image below):
the app opens with a view (map) partially visible and the RecyclerView at a default anchor point (center image)
user scrolls the RecyclerView up, the map collapses and the list continues scrolling (right image)
user scrolls the RecyclerView down, the map expands to a maximum point (note the list should not slide completely off screen but to some anchored point) (left image)
To create this we need 1 Activity and 3 Fragments.
The Activity will host a TabLayout and a ViewPager like so:
<LinearLayout 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.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" />
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
Since we only need to do the sliding behavior for the 1st Fragment the first Fragment gets an XML layout like so:
<android.support.design.widget.CoordinatorLayout
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.support.design.widget.AppBarLayout
android:id="#+id/appBarLayout"
android:layout_width="match_parent"
android:layout_height="400dp"
android:orientation="vertical"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsingToolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<com.google.android.gms.maps.MapView
android:id="#+id/mapView"
app:layout_collapseMode="parallax"
android:layout_height="400dp"
android:layout_width="match_parent" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
You can make the other Fragments however you like I just created fake data and a simple RecyclerView in the other Fragments.
Then call these views in your Activity and Fragment like so:
Activity
public class MainActivity extends AppCompatActivity {
private TabLayout mTabLayout;
private ViewPager mViewPager;
private SampleViewPagerAdapter mViewPagerAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.another_activity);
mTabLayout = (TabLayout) findViewById(R.id.sliding_tabs);
mViewPager = (ViewPager) findViewById(R.id.viewpager);
mViewPagerAdapter = new SampleViewPagerAdapter(getSupportFragmentManager());
mViewPager.setAdapter(mViewPagerAdapter);
mTabLayout.setupWithViewPager(mViewPager);
}
}
ViewPager Adapter
public class SampleViewPagerAdapter extends FragmentPagerAdapter {
public SampleViewPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new MapFragment();
case 1:
return new ScrollFragment();
case 2:
return new ScrollFragment();
default:
return new ScrollFragment();
}
}
#Override
public int getCount() {
return 3;
}
#Override
public CharSequence getPageTitle(int position) {
String[] tabNames = {"Stops", "Planner", "Alerts"};
return tabNames[position];
}
}
Map Fragment with Sliding RecyclerView
public class MapFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.activity_main, null);
initCollapsingToolbar(root);
// Initialize map
initFragment();
return root;
}
private void initCollapsingToolbar(View root) {
CollapsingToolbarLayout collapsingToolbarLayout =
(CollapsingToolbarLayout) root.findViewById(R.id.collapsingToolbar);
collapsingToolbarLayout.setContentScrimColor(getResources().getColor(R.color.cyan_500));
}
private void initFragment() {
FakeDataFragment fragment = new FakeDataFragment();
getChildFragmentManager().beginTransaction()
.replace(R.id.content, scrollFragment)
.commit();
}
}
You should get something like this then:
Setting the position:
You can programmatically collapse the toolbar (CollapsingToolbarLayout) using the following code:
public void collapseToolbar(){
CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) mFrameLayout.getLayoutParams();
AppBarLayout.ScrollingViewBehavior behavior = (AppBarLayout.ScrollingViewBehavior) params.getBehavior();
if (behavior != null) {
behavior.onNestedFling(rootLayout, appbarLayout, null, 0, 10000, true);
}
}
This means when the User first sees the map the map is partially collapsed to your Default State.
