I have following code in my Fragment to setup toolbar :
with(root) {
with(activity as AppCompatActivity) {
setupActionBar(toolbar) {
setDisplayHomeAsUpEnabled(true)
setDisplayShowHomeEnabled(true)
}
}
toolbar.setNavigationOnClickListener { activity?.finish() }
}
Here is my setupActionBar method :
fun AppCompatActivity.setupActionBar(toolbar : Toolbar, action: ActionBar.() -> Unit) {
setSupportActionBar(toolbar)
supportActionBar?.run {
action()
}
}
And toolbar in my layout :
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"

When I click on toolbar, it does not navigate me back to previous screen. It seems that it is not clickable.
(activity as AppCompatActivity).setSupportActionBar(toolbar)
(activity as AppCompatActivity).supportActionBar?.setDisplayHomeAsUpEnabled(true)
then in your fragment
override onOptionsItemSelected
override fun onOptionsItemSelected(item: MenuItem?): Boolean {
when (item?.itemId) {
android.R.id.home -> {
activity?.onBackPressed()
}
}
return true
}
Add the toolbar to your fragment xml
And try this code in your onCreateView
Toolbar toolbar = view.findViewById(R.id.toolbar); toolbar.setNavigationIcon(R.drawable.ic_back_button); toolbar.setNavigationOnClickListener(new View.OnClickListener() { #Override public void onClick(View v) { getActivity().onBackPressed(); } });
Toolbar should not be :
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:theme="#style/Toolbar"/>
Rather it should be :
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:theme="#style/Toolbar"/>

My toolbar on top of my activity appears blank but it should have a navigation custom icon and a title but neither is visible?
Here is my xml
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="?android:attr/actionBarSize"
android:minHeight="?android:attr/actionBarSize"

here is my activity
class MyActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_me)
setupToolbar()
}
private fun setupToolbar() {
setSupportActionBar(toolbar)
toolbar.setNavigationIcon(R.drawable.ic_close)
toolbar.setNavigationOnClickListener {
onBackPressed()
}
toolbar.setTitle(R.string.profile_unfollow_warning)
supportActionBar!!.setHomeButtonEnabled(true)
supportActionBar!!.setDisplayShowCustomEnabled(true)
supportActionBar!!.setDisplayHomeAsUpEnabled(true)
supportActionBar!!.show()
}
}
Theme i am using for this activity
<activity android:name=".ui.profile.MyActivity"
android:label="#string/app_name"
android:launchMode="singleTop"
android:screenOrientation="portrait"
android:theme="#style/Theme.MaterialComponents.NoActionBar"/>
public class MainActivity {
// Declaring the Toolbar Object
private Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
// Attaching the layout to the toolbar object
toolbar = (Toolbar) findViewById(R.id.tool_bar);
// Setting toolbar as the ActionBar with setSupportActionBar() call
setSupportActionBar(toolbar);
}
Create a xml file like tool_bar.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorPrimary"
android:elevation="4dp" />
Include the Toolbar into your main_activity.xml
<RelativeLayout 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"
tools:context=".MainActivity">
<include
android:id="#+id/tool_bar"
layout="#layout/tool_bar" />
<TextView
android:layout_below="#+id/tool_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/TextDimTop"
android:text="#string/hello_world" />
</RelativeLayout>
Opps, It seems to be a bug in ordering
setSupportActionBar(toolbar)
supportActionBar?.setDisplayHomeAsUpEnabled(true)
supportActionBar?.setTitle(R.string.profile_unfollow_warning)
supportActionBar?.setHomeButtonEnabled(true)
supportActionBar?.setDisplayShowCustomEnabled(true)
toolbar?.setNavigationIcon(R.drawable.ic_close)
toolbar?.setNavigationOnClickListener {
onBackPressed()
}
I want something like this:
I have the following now:
With the following XML:
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent"

app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior">

android:layout_width="match_parent"
android:layout_height="wrap_content"

<android.support.design.widget.FloatingActionButton
android:layout_height="wrap_content"

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
xmlns:android="http://schemas.android.com/apk/res/android"

</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:elevation="4dp"
android:id="#+id/collapsing_toolbar"
android:background="#color/primary"
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.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
<android.support.design.widget.FloatingActionButton
style="#style/fab"
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
Collapsing Toolbar with Fab
I'm trying to use navigation drawer and bottom bar nav in my app.therefore i have created navigation activity first.then i tried to add bottom bar nav to that same activity. I want to develop like this app:
without BottomNavigationView in Activity.xml,app is working.but when i add BottomNavigationView inside Activity.xml app crashed.nothing showing in logcat.
how can i use both bottombar nav and navigation drawer in same activity,please give me an simple example? thx
I am using Navigation Architecture Component following version:
def nav_version = "2.0.0"
implementation "androidx.navigation:navigation-fragment:$nav_version"
implementation "androidx.navigation:navigation-ui:$nav_version"
And below is a simple code to use BottomNavigation and Navigation Drawer
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
private static final String TAG = "debinf MainActivity";
//public static final String FRAGMENT_KEY = "fragment";
private BottomNavigationView bottomNavigationView;
private NavigationView navigationView;
private DrawerLayout drawerLayout;
private NavController navController;
private AppBarConfiguration appBarConfiguration;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.i(TAG, "onCreate: ");
bottomNavigationView = (BottomNavigationView) findViewById(R.id.main_bottomnav);
navigationView = (NavigationView) findViewById(R.id.main_sidebar);
drawerLayout = (DrawerLayout) findViewById(R.id.main_drawer);
setupNavigation();
}
private void setupNavigation() {
Log.i(TAG, "setupNavigation: ");
navController = Navigation.findNavController(this, R.id.main_fragment);
appBarConfiguration =
new AppBarConfiguration.Builder(navController.getGraph()) //Pass the ids of fragments from nav_graph which you dont want to show back button in toolbar
.setDrawerLayout(drawerLayout)
.build();
NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration); //Setup toolbar with back button and drawer icon according to appBarConfiguration
NavigationUI.setupWithNavController(navigationView, navController);
NavigationUI.setupWithNavController(bottomNavigationView, navController);
/*
** Listener for bottomNavigation must be called after been setupWithNavController
** This command will override NavigationUI.setupWithNavController(bottomNavigationView, navController)
** and the automatic transaction between fragments is lost
* */
//bottomNavigationView.setOnNavigationItemSelectedListener(this);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
Log.i(TAG, "onBackPressed: ");
if (drawerLayout.isDrawerOpen(GravityCompat.START)) {
Log.i(TAG, "onBackPressed: DRAWER IS OPEN - CLOSING IT");
drawerLayout.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override
public boolean onSupportNavigateUp() {
Log.i(TAG, "onSupportNavigateUp: ");
// replace navigation up button with nav drawer button when on start destination
return NavigationUI.navigateUp(navController, appBarConfiguration) || super.onSupportNavigateUp();
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
Log.i(TAG, "onNavigationItemSelected: SIDE BAR");
if (drawerLayout.isDrawerOpen(GravityCompat.START)) {
drawerLayout.closeDrawer(GravityCompat.START);

If you using includes. Just wrap app bar include with bottom navigation in some layout. For example I'm using ConstraintLayout for most of time.

That's all.
Add a parent to <include ..../> then add BottomNavigationView
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<include
layout="#layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#color/colorPrimary"
app:itemTextColor="#color/colorAccent"
app:menu="#menu/bottom_navigation_menu"/>
</RelativeLayout>
Use TabLayout instead of bottom navigation
TabLayout is better and easier
create root.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

How can I set Elevation to 0 or disable it for a specific Fragment of my NavigationDrawer? Programmatically or with theme maybe ?
toolbar.setElevation(0) seems not working.
This ìn my onNavigationItemSelected doesn't work, elevation won't change :
if (item.getItemId() == R.id.drawer_menu_account) {
if (getSupportActionBar() != null) {
getSupportActionBar().setElevation(0);
}
} else {
if (getSupportActionBar() != null) {
getSupportActionBar().setElevation(8);
}
}
And there is my Coordinator layout with Toolbar
<?xml version="1.0" encoding="utf-8"?>

</android.support.design.widget.AppBarLayout>

android:layout_width="wrap_content"

</android.support.design.widget.CoordinatorLayout>
RESOLVED - Thanks to Amir ! Work with this in my onNavigationItemSelected
if (android.os.Build.VERSION.SDK_INT >= 21) {
if (item.getItemId() == R.id.drawer_menu_account) {
appBar.setElevation(0);
} else {
appBar.setElevation(8);
}
}
To remove shadow in Toolbar use
app:elevation="0" in AppBarLayout xml or
use mAppBarLayout.setTargetElevation(0) in java.
It worked for me.
I'm trying to show my FloatingActionButton on top of the SnackBar but I just can't make it as I have done on other screens. My current layout is this one:
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
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:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:elevation="#dimen/toolbar_elevation"
android:minHeight="?attr/actionBarSize"
app:popupTheme="#style/AppTheme.ToolbarPopUp"
app:theme="#style/AppTheme.Toolbar"/>
<android.support.design.widget.TabLayout
android:id="#+id/sliding_tabs"
style="#style/Feed.TabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="4dp"/>
<android.support.design.widget.CoordinatorLayout
android:id="#+id/coordinator_fab"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
style="#style/FloatingActionButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:src="#drawable/ic_start"
app:backgroundTint="#color/h19_green"
app:elevation="6dp"
app:pressedTranslationZ="12dp"/>
</android.support.design.widget.CoordinatorLayout>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/navdrawer"/>
</android.support.v4.widget.DrawerLayout>
And my Snackbar code is this one:
#Override
public void alertNoInternetConnection() {
CoordinatorLayout coordinatorLayout = ButterKnife.findById(getActivity(), R.id.coordinator_fab);
Snackbar.make(coordinatorLayout, R.string.connection_offline, Snackbar.LENGTH_INDEFINITE).show();
}
How should I reorganize my layout so that when I display the Snackbar, the Floating Action Button hovers above it?
I was looking quite long for the answer, and finally I've found the solution which worked for me:
FloatingActionButton must be inside CoordinatorLayout
Snackbar should receive FloatingActionButton as it's View argument
Layout:
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.FloatingActionButton
android:id="#+id/fabAdd"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:src="#mipmap/ic_create_white_48dp"
/>
</android.support.design.widget.CoordinatorLayout>
Code:
FloatingActionButton fabAdd = (FloatingActionButton)findViewById(R.id.fabAdd);
Snackbar.make(fabAdd, "Record was removed.", Snackbar.LENGTH_SHORT).show();
Try adding this to your FAB:
app:layout_anchor="#id/coordinator_fab"
app:layout_anchorGravity="bottom|right"
and remove:
android:layout_gravity="bottom|end"
Your layout implementation is wrong, here's the right implementation (for example):
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
... >
<android.support.design.widget.CoordinatorLayout
android:id="#+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_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="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways"/>
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</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.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:layout_margin="#dimen/fab_margin"
android:src="#drawable/ic_done" />
</android.support.design.widget.CoordinatorLayout>
<include layout="#layout/navdrawer"/>
</android.support.v4.widget.DrawerLayout>
And then, to show the Snackbar correctly:
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Here's a Snackbar", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
The problem is that according to the google guidelines you should not display the FAB above the Snackbar you should swipe the FAB and display the Snack bar below it
check this link :
http://www.google.com/design/spec/components/snackbars-toasts.html#snackbars-toasts-usage
this worked for me.
<android.support.design.widget.CoordinatorLayout
android:id="#+id/rootLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<android.support.design.widget.FloatingActionButton
... />
fabBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Snackbar.make(rootLayout, "Hello. I am Snackbar!",
Snackbar.LENGTH_SHORT)
.setAction("Undo", new View.OnClickListener() {
#Override
public void onClick(View v) {
}
})
.show();
}
});
