How to remove the shadow under Action bar

I have been trying to get the shadow under the app Action bar to disappear but it wont which is very annoying. iI have set the theme to NoActionBar and opted to using toolbar instead.
And have i have also set the elevation to 0dp in my activity.java
package com.example.drawerlayout;
import androidx.appcompat.app.ActionBarDrawerToggle;
import androidx.appcompat.app.AppCompatActivity;
import androidx.drawerlayout.widget.DrawerLayout;
import android.os.Bundle;
import android.view.MenuItem;
import androidx.appcompat.widget.Toolbar;
import com.google.android.material.appbar.AppBarLayout;
public class MainActivity extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mToggle;
private Toolbar mToolbar;
private AppBarLayout actionLayout;
private Toolbar t;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.open, R.string.close);
mToolbar = (Toolbar) findViewById(R.id.nav_action);
setSupportActionBar(mToolbar);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setElevation(0);
}
}
The Toolbar looks thus:
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.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="wrap_content">
<com.google.android.material.appbar.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.appcompat.widget.Toolbar
android:id="#+id/nav_action"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/mm_blue" />
</com.google.android.material.appbar.AppBarLayout>
</androidx.coordinatorlayout.widget.CoordinatorLayout>

Simply add app:elevation="0dp"
<com.google.android.material.appbar.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:elevation="0dp">
<!-- Toolbar -->
</com.google.android.material.appbar.AppBarLayout>

Set this property toolbar:elevation="0dp" to AppBarLayout to remove shadow from Toolbar.
eg-
<com.google.android.material.appbar.AppBarLayout
android:id="#+id/appbar"
toolbar:elevation="0dp"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.appcompat.widget.Toolbar
android:id="#+id/nav_action"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/mm_blue" />
</com.google.android.material.appbar.AppBarLayout>

Check below code
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.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="wrap_content">
<com.google.android.material.appbar.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="0dp"
app:elevation="0dp">
<androidx.appcompat.widget.Toolbar
android:id="#+id/nav_action"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/mm_blue" />
</com.google.android.material.appbar.AppBarLayout>
</androidx.coordinatorlayout.widget.CoordinatorLayout>

Just remove the AppBar layout and directly put your toolbar in the coordinate layout:
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.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="wrap_content">
<androidx.appcompat.widget.Toolbar
android:id="#+id/nav_action"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/mm_blue" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
Try this may it should help you out.

Toolbar Bug when show keyboard

I'm setting the background color of the toolbar programmatically on the main activity's onCreate.
toolbar = (Toolbar) findViewById(R.id.toolbar);
settings = getSharedPreferences(Constants.SETTING, 0);
primaryColor = settings.getString("primaryColor", "#5500FF");
appName = settings.getString("appName", "Catálogo");
colorPrimaryDraw = new ColorDrawable(Color.parseColor(primaryColor));
//setar nome do app e cor de fundo no toolbar
toolbar.setTitle(appName);
toolbar.setBackground(colorPrimaryDraw);
toolbar.setTitleTextColor(Color.WHITE);
setSupportActionBar(toolbar);
toolbar ok
But when the keyboard is open the part of the toolbar icon changes to another color.
Open keyboard
Any tips on how to solve this?

android - menu item not showing in action bar

I'm trying to add menu item "done" in the action bar. I just copied and modified the code from another activity that has menu items showing. So it should work properly.
Here's the activity layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
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: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="?attr/actionBarSize"
android:background="#color/md_blue_600"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways"/>
</android.support.design.widget.AppBarLayout>
<LinearLayout
android:id="#+id/activity_credits"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#fff"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:orientation="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:mContext="com.getsaveit.saveit.activities.CreditsActivity">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textStyle="bold"
android:textSize="18sp"
android:layout_marginBottom="#dimen/activity_vertical_margin"
android:text="#string/affiliator_category"/>
<com.toptoche.searchablespinnerlibrary.SearchableSpinner
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:hintText="Select category"
android:id="#+id/affiliator_category_spinner"/>
<ExpandableListView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/rectangular_shap"
android:id="#+id/affiliators_listview"/>
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
And choose_affiliator_menu.xml file :
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:title="#string/done"
android:orderInCategory="1"
android:id="#+id/next_btn"
app:showAsAction="always" />
</menu>
And the java code itself:
public class CreditsActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_credits);
Toolbar actionBar = (Toolbar) findViewById(R.id.toolbar);
actionBar.setTitle("Memberships");
//....
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.choose_affiliator_menu, menu);
return true;
}
}

You should use below method after initialization of Toolbar.
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

Android - fragments don't show

I created one acivity and a few fragments. I try to show one of them after start-up but I see empty screen, without fragments (but with NavigationDrawer)
What do I do wrong?
I have no idea where my mistake is.
Thank you!
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportFragmentManager().beginTransaction()
.replace(R.id.content, new DashboardFragment()).commit();
...
public class DashboardFragment extends Fragment {
...

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

<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/scrollView"
tools:context=".MainActivity">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/view">

android:id="#+id/textView"
android:text="Week info \n\n"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</android.support.v7.widget.CardView>
</RelativeLayout>
</ScrollView>
</FrameLayout>

first you should add fragment :
FragmentManager fm=getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.add([FRAGMENT],[STRING TAG]);
ft.commit();

Android L support library Toolbar appears under views

I have a mainactivity.xml that has a framelayout and inside that has a toolbar
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
tools:ignore="MergeRootFrame" >
<android.support.v7.widget.Toolbar
android:id = "#+id/toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary" />
</FrameLayout>
Inside my mainactivity.java, I have this
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
getFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment())
.commit();
}
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
Based on the tutorial here, http://android-developers.blogspot.com/2014/10/appcompat-v21-material-design-for-pre.html, I should have a custom Toolbar that acts as an actionbar. However, the toolbar that appears happens under the fragments that I add in the block. The toolbar is supposed to appear above them and shift them downwards, but now the views cover the actionbar toolbar. Is this a glitch or am I simply forgetting something? This actually worked before but is now broken for some reason.

The Toolbar needs to be outside of the FrameLayout that is going to hold your Fragment like so:
<LinearLayout 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"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id = "#+id/toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary" />
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
tools:ignore="MergeRootFrame" >
</FrameLayout>
</LinearLayout>
