Try changing the style of the main activity (the one causing the issues) in the manifest, that should do it. You can check the default values when you create a new project using the "Basic Activity" template.
In this case since your layout contains a toolbar you should use the default theme (or a custom one to the same effect): android:theme="#style/AppTheme.NoActionBar". Notice that I´m using the default values of the template. The style you need should be something like this:
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
This would be the manifest entry:
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
BTW, just in case you havent done it, consider testing with the same API level in all devices (virtual and physical) to get consistent test results.
Hope it helps!
On Android I can set a transparent statusbar with the following style line:
<item name="android:windowTranslucentStatus">true</item>
I would like to display a text directly under the statusbar with the same background color of the statusbar. My problem is if I set the background color to my primaryColor it is a bit brighter because I haven't added the alpha value of the statusbar to the color.
So how can I get the alpha value of the statusbar from code to add it to my background color?
Do you want like this ?
If yes. After Android 5.0.
You should set colorPrimaryDark same as colorPrimary.
colorPrimaryDark means status bar color.
And one important step, if your layout code like this:
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
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" />
</android.support.design.widget.AppBarLayout>
Delete "AppBarLayout". Change to :
<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" />
On Activity, try get this
window.statusBarColor
I have following setup:
I'm using AppCompat
MainActivity, that holds a fragment and has a toolbar, that's hiding when scrolling down
Fragment with RecyclerView
all views that should fit the screen have the according android:fitsSystemWindows="true" in the xml layout
The problem is, I can't get the statusbar transparent in this case. What I do is following:
Create the activity and call setContent
Then I try to adjust the activity to programmatically get a translucent toolbar like following:
#TargetApi(Build.VERSION_CODES.LOLLIPOP)
public void themeNavAndStatusBar(Activity activity)
{
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP)
return;
Window w = activity.getWindow();
w.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
w.setFlags(
WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION,
WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
w.setFlags(
WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,
WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
w.setNavigationBarColor(activity.getResources().getColor(android.R.color.transparent));
w.setStatusBarColor(activity.getResources().getColor(android.R.color.transparent));
}
Replace the placeholder in the activity (#+id/frame_container) with the fragment
The statusbar is solid colored in this case, and the views are not drawn underneath it... Why?
What I want
I want a toolbar, that is scrolled of the screen and hiding completely while the content underneath this toolbar should fitScreen and be drawn behind the transparent nav bar.

Here's my main activity:

</RelativeLayout>
EDIT - Screenshots
I use a light/dark base theme and theme everything by hand (because the user can select any color as primary/accent color), so don't mind that the toolbar is white (it's the default's theme background color and primary color). I added a black border as well so that you see where the activity ends...
First Screenshot: Shows the toolbar, nothing is scrolled
Second Screenshot: I just started scrolling => the toolbar now should scroll away
Third Screenshot: the main content should now scroll underneath the nav bar...
In the end, I'll of course make the toolbar and navbar semi transparent for a better visual effect...
tl;dr Set android:fitsSystemWindows="false" at least to the root CoordinatorLayout and to the inner fragment container, #frame_container.
This might not be the final solution (i.e. there might be other fitsSystemWindows to change) so tell me if you have any problems.
why
When it comes to status bar, I think of fitsSystemWindows like so:
fitsSystemWindows="false" : draws the view normally, under the status bar because of the window flags you have set.
fitsSystemWindows="true" : draws the view normally, under the status bar because of the window flags you have set, but adds a top padding so that content is drawn below the status bar and they don't overlap.
In fact, in my opinion, the white you see is not the status bar color, but rather your CoordinatorLayout background. That is due to fitsSystemWindows="true" on the coordinator: it draws the background to the whole window, but adds top padding to the content so inner views are not covered by status bar.
This is not what you want. Your inner content must be covered by the status bar, and so you have to set fitsSystemWindows="false" to the coordinator (so it won't apply top padding) and probably to the content itself.
Once you get how it works, it is easy to debug and achieve the effect you are looking for. Actually, it is not. Years pass, but I still spend hours trying to figure out the right fitsSystemWindows combination, because most Views (in the support libraries at least) override the default behavior that I stated above, in ways that are mostly not intuitive. See this post for a small guide on how to use it.
Edit your styles.xml (v21) , add the following style
<style name="AppTheme.Home" parent="AppTheme.Base">
<!-- Customize your theme here. -->
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:windowTranslucentNavigation">true</item>
</style>
You can change parent theme as per your liking, but now declare this theme in your AndroidManifest.xml file for a particular activity like this :
<activity
android:theme="#style/AppTheme.Home"
android:name=".HomeActivity"
android:launchMode="singleTop"
android:screenOrientation="portrait" />
This will let your content visible under the transparent actionbar.
Now use the following to align your toolbar below the StatusBar properly, call this in your oncreate:
toolbar.setPadding(0, getStatusBarHeight(), 0, 0);
Get statusbar height using following :
public int getStatusBarHeight() {
int result = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
result = getResources().getDimensionPixelSize(resourceId);
}
return result;
}
Remove the following from your coordinator layout tags :
android:fitsSystemWindows="true"
Now in order to collapse your toolbar or hide it you may refer to this tutorial
Make sure you are using following version of design support library, as it is bug free :
compile 'com.android.support:design:23.1.0'
After reading your descriptions about your question, I thought styles of Google Photos matches your requirement.
OK, there are just some tips for your question. After my test, it works.
If you want to show content behind status bar, you need add <item name="android:windowTranslucentStatus">true</item> into your
style when Android version level is larger than 19(namely KitKat)
If you want to show content behind navigation bar, you need add
<item name="android:windowTranslucentNavigation">true</item> into your
style when Android version level is larger than 19(namely KitKat)
If you want to hide Toolbar smoothly when content is scrolled up
and to show Toolbar smoothly when content is scrolled down, you
need to add app:layout_collapseMode="parallax" into your
Toolbar's attributes based on your current codes.Of course, you
need coordinate Toolbar with CollapsingToolbarLayout
CoordinatorLayout and AppBarLayout.
as some users said, by setting android:fitsSystemWindows="false", the layout overlapped below statusbar.
I solved it by setting android:fitsSystemWindows="true" and in CoordinatorLayout tag setting app:statusBarBackground="#android:color/transparent".
For me, the reason was not that it did not work per se, but that I use the material drawer library from Mike Penz and this library does use fullscreen + offset + custom background behind the toolbar so I had to solve the problem respecting that special setup...
I'll reward the points to the in my opinion most informative answer though...
I had the same issue and my solution was add android:fitsSystemWindows="true" to the DrawerLayout
<android.support.v4.widget.DrawerLayout 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/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
....
</android.support.v4.widget.DrawerLayout>
I had relevant issues depend on android:fitsSystemWindows setting.
Once false:
Snacks was drawn under the Navigation bar
Once true:
Status bar had none transparent background
Solution was really simple...
Just to add android:layout_marginBottom="48dp". to CoordinatorLayout like that:
just to add <android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:map="http://schemas.android.com/apk/res-auto"
tools:context=".MapsActivity"
android:id="#+id/coordinatorLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="false"
android:layout_marginBottom="48dp">
Theoretically Navigation bar should have fixed size "48dp", but in future releases potentially it may change (like Status bar got slimmer by 1dp in Marshmallow), so I wouldn't rely on fixed size.
Better additionally get it and apply on run time.
If You are using Google Map like me You may want to know ActionBar/Toolbar size and the navigation bar in run time:
in onCreate use this code:
final TypedArray styledAttributes = MapsActivity.this.getTheme().obtainStyledAttributes(
new int[]{android.R.attr.actionBarSize});
mToolbarHeight = (int) styledAttributes.getDimension(0, 0);
styledAttributes.recycle();
// translucent bars code. Will not fire below Lollipop
// Ask NavigationBar Height
ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.coordinatorLayout),
new OnApplyWindowInsetsListener() { // setContentView() must be fired already
#Override
public WindowInsetsCompat onApplyWindowInsets(View v, WindowInsetsCompat insets) {
statusBar = insets.getSystemWindowInsetTop(); // You may also need this value
mNavBarHeight = insets.getSystemWindowInsetBottom();
if (mMap != null)
mMap.setPadding(0, mToolbarHeight, 0, mNavBarHeight);
// else will be set in onMapReady()
SharedPreferences.Editor editor = mSharedPref.edit();
editor
.putInt(NAVBAR_HEIGHT_KEY, mNavBarHeight)
.commit(); // Save the results in flash memory and run the code just once on app first run instead of doing it every run
return insets;
}
}
);
And what's important. If You got some additional layers like drawer etc put them encapsulating the CoordinatorLayout inside rather than outside as otherwise it will make other views inside shorter by the marginBottom
Here's what I did to have the toolbar have the same color as the status bar, by getting the status bar transparent:

You should add the following code to your theme, this code will make the status bar transparent:
<item name="android:windowTranslucentStatus" tools:targetApi="kitkat">true</item>
Additionally, add scroll behavior to your top app bar. The following example shows the top app bar disappearing upon scrolling up, and appearing upon scrolling down:
<androidx.coordinatorlayout.widget.CoordinatorLayout
...>
<com.google.android.material.appbar.AppBarLayout
...>
<com.google.android.material.appbar.MaterialToolbar
...
app:layout_scrollFlags="scroll|enterAlways|snap"
/>
</com.google.android.material.appbar.AppBarLayout>
...
</androidx.coordinatorlayout.widget.CoordinatorLayout>
First add this code to AppBarLayout:
app:liftOnScroll="true"
Then update your "app:layout_scrollFlags" in your toolbar:
app:layout_scrollFlags="scroll|enterAlways|snap"
This will work, I am pretty sure.
I've created a new project with a new blank activity using Android Studio and I'm trying to remove the shadow below the toolbar in >=API21. I've tried many things.
This works for < API21
<item name="android:windowContentOverlay">#null</item>
This doesn't work for me in phone with >=API21:
getSupportActionBar().setElevation(0);
<item name="android:elevation">0dp</item>
I don't know what else I can try. Any help is appreciated.
EDIT: I've tried everything from other questions like this but nothing worked.
As #Vipul Asri said, I had to add app:elevation="0dp" but I was adding it to the wrong place. This works:
<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:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="android.teechart.steema.com.androiddemo.DashboardWebAnalytics">
<android.support.design.widget.AppBarLayout
app:elevation="0dp"
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" />
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_dashboard_web_analytics" />
</android.support.design.widget.CoordinatorLayout>
I was adding it in android.support.v7.widget.Toolbar but the correct place was in android.support.design.widget.AppBarLayout.
This shadow is part of windowContentOverlay on APIs below LOLLIPOP (on LOLLIPOP it's #null).
When you work with Toolbar widget the toolbar isn't part of window decor anymore so the shadow starts at the top of the window over the toolbar instead of below it (so you want the windowContentOverlay to be #null). Additionally you need to add an extra empty View below the toolbar pre-LOLLIPOP with its background set to a vertical shadow drawable (8dp tall gradient from #20000000 to #00000000 works best). On LOLLIPOP you can set 8dp elevation on the toolbar instead.
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/purple"
android:minHeight="?attr/actionBarSize"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
When I use the setTitle() method, it all works fine. But the problem is that when I change orientation (since in lollipop 5.1 I can do so) the title word is small compared to portrait version. Why such bug? and how do I solve this?
By default the Toolbar's fontsize is smaller in landscape.
If you want it to have the same size as in portrait you can set a custom titleTextAppearance:
<android.support.v7.widget.Toolbar
app:titleTextAppearance="#style/YourToolbarTitleStyle"
.../>
with YourToolbarTitleStyle being defined as a style where you specify a text size:
<style name="YourToolbarTitleStyle" parent="#style/TextAppearance.Widget.AppCompat.Toolbar.Title">
<item name="android:textSize">20sp</item>
</style>
