I have a material design navigation drawer i created from this tutorial.
It works perfect with toolbar and all. I can click on an item in the drawer and the respective fragment is displayed plus the title.
However i would like to make the toolbar on one fragment to be transparent so that the background image is displayed like in the image below:
PROBLEM: My problem is the fragment doesnt seem to start over the toolbar but below it.This is the result:
I dont know how to fix this.Any suggestions will be welcomed.
Use this for toolbar.xml:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="#drawable/toolbar_image"/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
local:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
local:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
</FrameLayout>
Of course, you'll need to change "#drawable/toolbar_image" to the drawable that you want to use for the background image.

Assuming you did not modify any properties in style.xml, the Layout Editor in Android Studio displays the Action Bar as:
By adjusting the style of the action bar, I can do things like adjust the background color of it.
However, the ActionBar I use is a Toolbar that uses a custom layout that can not be expressed simply by adjusting the properties of the action bar, as shown below.
It is not difficult to apply the above layout to the Action Bar during runtime. (change custom view, or apply AppTheme to NoActionBar, then set SupportActionBar)
What I really want is that the AppBar with these custom layouts will print out all of the xml inside the project I'm working on, but I have not found the right answer for it so far.
Is this an operation not supported by the Android studio?
You can achieve this via ToolBar & FrameLayouts,
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/coordinator_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="?actionBarSize">
<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="match_parent"
android:background="?attr/colorPrimary"
app:contentInsetStart="0dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
//TextView
//ImageView
// etc
</LinearLayout>
</android.support.v7.widget.Toolbar>
</FrameLayout>
<FrameLayout
android:id="#+id/main_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?actionBarSize">
</FrameLayout>
Organize your host activity layout as above and load fragments inside the main_container
I want an invisible toolbar but I want the back arrow and title to be displayed.
For achieving this, I did the following:
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.abc.xyz.AboutActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay"
android:background="#color/toolbarTransparent">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"/>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/header_about"
android:layout_width="match_parent"
android:layout_height="160dp"
android:background="#color/colorAccent"/>
<ImageView
android:id="#+id/a"
android:layout_width="match_parent"
android:layout_height="70dp"
android:src="#drawable/a"
app:layout_anchor="#id/header_about"
app:layout_anchorGravity="bottom|center"/>
<include layout="#layout/content_about"/>
</android.support.design.widget.CoordinatorLayout>
But, I'm getting the following result (Look how toolbar is still appearing to be there):
I want the toolbar to get invisible and only the title and back arrow to be shown.
Please let me know how can I achieve that.
Sorry for bad format of the question. I'm still a beginner here.
AppBarLayout has default elevation value and that is why you can see shadow. You can set AppBarLayout elevation to 0dp
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay"
app:elevation="0dp"
android:background="#color/toolbarTransparent">
or just remove AppBarLayout. Toolbar is transparent by default.
If you want to use AppBarLayout with transparent background on Android Lolipop version and greater - set outline provider to BACKGROUND like below:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
appBarLayout.setOutlineProvider(ViewOutlineProvider.BACKGROUND);
}
In this case when your background is transparent shadow will be not visible.
please check the android manifest file it should have AppTheme.NoActionBar then u will be able to hide it
I'm looking for a custom TabLayout. The icon of the Tab in the middle needs a margin to overlay the content. Please check out the image below.
What I've tried so far
Tab.setCustomView() with a margin. That doesn't overlay the content though.
Looked for TabLayout libraries that give such flexibility. Didn't find anything that fits my need.
Re-invent the wheel?
Since I don't need any complicated scrolling functionality, I could develop my own TabLayout with a couple ViewGroups,TextView and ImageView. Before I have to do that:
Do you know of any library that would do that?
How would you approach it?
Any help would be greatly appreciated!
I achieved that by the combination of a custom library and the floating action button.
The library: MagicIndicator on GitHub
I set the icon of the middle fragment to an empty icon and positioned the floating action button in the middle to overlay the TabLayout. It looks like this:
My activity layout:
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".MainActivity">
<android.support.v4.view.ViewPager
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="top"
android:layout_marginBottom="50dp"
app:layout_behavior="#string/appbar_scrolling_behavior" />
<net.lucode.hackware.magicindicator.MagicIndicator
android:id="#+id/magic_indicator"
android:layout_width="match_parent"
android:layout_height="50dp"
android:background="#color/light_gray"
android:layout_gravity="bottom" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center|bottom"
android:layout_margin="10dp"
app:srcCompat="#drawable/add_icon"
app:backgroundTint="#color/colorPrimary"/>
</android.support.design.widget.CoordinatorLayout>
I'm looking for best practices when it comes to the following pretty common setup:
What I'm currently doing is:
My Main Activity has a navigation drawer and a Toolbar.
When you click on one of the list items inside the drawer a fragment is loaded under the toolbar. Some fragments have their own tabs inside using viewpager ect.
I would like to make use of the material functionalities like hiding the toolbar while scrolling ect. It is no problem to get it done.
But there is a problem when only some of your fragments would like to make use of the scrolling toolbar. Using a normal Scrollview does solve the problem if you can add an additional margin at the bottom, but once you have a keyboard it will mess up as the scroll is wrong. Using a nestedscrollview works but does scroll the toolbar.
So how can I avoid the scrolling toolbar when my activity holds the toolbar and some fragments that scroll should make use of it and some not?
Is the architectural design wrong? Another thing I thought is to have the different toolbars inside of each fragment... but they have to share the same navigation drawer so you have to create and add the ToggleButton each time? Is it the right approach ? Should I go that path? I'm not convinced and would like to have the opinion of somebody more experienced then me. What's the best solution in this case.
Appreciate your help!
Cheers

I am also Using navigation drawer and tool bar please import project from this link
And try to understand how to use navigation drawer and tool bar using fragment
My app contains a DrawerLayout and inside it I include the appcompat toolbar.
Everything works fine when the drawer "opens" the fragments but when from fragment I start an activity and then it shows the action mode menus, they are shown on top of the toolbar but I want it over the toolbar in the same manner fragments work.
This effect is present on Android 5.0.1 and KitKat 4.4.2
No solution found on SO worked for me.
How can I fix it and show only the action mode over the toolbar when action mode menus are visible?
The image below shows the wrong result
This is the expected result
The called activity layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<include layout="#layout/toolbar_app"/>
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
The toolbar layout
<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/my_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
android:background="?attr/colorPrimary"/>
Adding <item name="windowActionModeOverlay">true</item> to the style will fix the issue
