How to start Drawer Layout below the toolbar in Android?

How to start Drawer Layout below the toolbar in Android? - android

Here is my main xml file:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
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:id="#+id/nav_drawer">
<android.support.design.widget.CoordinatorLayout
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.example.amit.rssreader.MainActivity">
<android.support.design.widget.AppBarLayout
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_main" />
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:layout_width="wrap_content"
android:layout_height="match_parent"
app:menu="#menu/navigation_menu"
android:layout_gravity="start">
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
This is what is happening
I want to have the drawer below the Action bar .This wasnt a navigation Drawer Activity, the navigation drawer has been added later by xml.

I think this might help you:
Modify the xml layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
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="wrap_content">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.DrawerLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<include layout="#layout/content_main" />
</android.support.design.widget.CoordinatorLayout>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
Create theme for activity without toolbar in values/styles.xml and apply it to your activity in AndroidManifest file:
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
And to make it working, make the onCreate method of your activity to look like this:
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
final DrawerLayout drawerLayout = (DrawerLayout)
findViewById(R.id.drawerLayout);
ActionBar supportActionBar = getSupportActionBar();
if(supportActionBar != null) {
supportActionBar.setDisplayHomeAsUpEnabled(true);
supportActionBar.setHomeButtonEnabled(true);
}
setSupportActionBar(toolbar);
final ListView drawerList = (ListView)
findViewById(R.id.drawerList);
drawerList.setAdapter(new ArrayAdapter<>(this, android.R.layout.simple_list_item_1,
new String[] { "Item 1", "Item 2", "Item 3" } ));
drawerLayout.setScrimColor(Color.TRANSPARENT);
ActionBarDrawerToggle actionBarDrawerToggle =
new ActionBarDrawerToggle(this, drawerLayout,
toolbar, R.string.app_name, R.string.app_name);
actionBarDrawerToggle.setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(drawerLayout.isDrawerOpen(drawerList)) {
drawerLayout.closeDrawers();
} else {
drawerLayout.openDrawer(drawerList);
}
}
});
drawerLayout.addDrawerListener(actionBarDrawerToggle);
actionBarDrawerToggle.syncState();
}
And this is how does it work.

In activity:
import androidx.appcompat.app.AppCompatActivity;

import androidx.appcompat.widget.Toolbar;
public class MainNavigationDrawerFragmentActivity extends AppCompatActivity{

mToolbar = (Toolbar) findViewById(R.id.toolBar);
setSupportActionBar(mToolbar);

getSupportActionBar().setDisplayShowTitleEnabled(false);
mDrawerToggle = new ActionBarDrawerToggle(
this,
mDrawerLayout,
mToolbar, R.string.application_name,
R.string.application_name) {
public void onDrawerClosed(View view) {
mToolbar.setTitle(mTitle);
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
mToolbar.setTitle(mDrawerTitle);
invalidateOptionsMenu();
loadDraftsTotalNumber();
loadActiveCart();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
and here layout:
<androidx.drawerlayout.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolBar"
android:layout_width="0dp"
android:layout_height="56dp"
android:background="#dc2700"
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<!-- Listview to display slider menu -->
<ListView
android:id="#+id/list_slidermenu"
android:layout_width="288dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#color/list_background"
android:choiceMode="singleChoice"
android:divider="#null"
android:listSelector="#drawable/list_selector"
android:paddingLeft="16dip"
android:paddingRight="16dip"/>
</androidx.drawerlayout.widget.DrawerLayout>
but toolbar not show:

Try this for your layout. It works for me.
<com.google.android.material.appbar.AppBarLayout
android:id="#+id/appBarLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/color3"
app:layout_constraintTop_toTopOf="parent">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolBar"
android:layout_width="0dp"
android:layout_height="56dp"
android:background="#dc2700"
/>
</com.google.android.material.appbar.AppBarLayout>

Try setting android:layout_width="match_parent" for toolBar
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolBar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"/>

I found solution
The toolbar AND FrameLayout must be inside LinearLayout:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolBar"
android:layout_width="match_parent"
android:layout_height="56dp"/>
<!-- Framelayout to display Fragments -->
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
</LinearLayout>
and here result:

android statusbar not showing on fragment

I am working on a to-do list app on android using a fragment on top of the main activity to add new items to the list. When the fragment is displayed on the screen it is shown below the status bar. I would like to be able to see the status bar and the fullscreen fragment. Here is the code:
Main Activity
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
private static Context mContext;
private static ArrayList<Task> mTaskList = new ArrayList<>();
private static RecyclerView mRecyclerView;
private static TaskListAdapter mAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mContext = this.getApplicationContext();
//TOOLBAR
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
//FAB - ADD NEW TASK
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
addNewTask();
}
});
//RECYCLER VIEW
setTaskData();
mRecyclerView = (RecyclerView) findViewById(R.id.rvTaskList);
mAdapter = new TaskListAdapter(getTaskData(), mContext);
mRecyclerView.setAdapter(mAdapter);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
private void addNewTask() {
FragmentManager fragmentManager = getSupportFragmentManager();
AddTaskDialogFragment newFragment = new AddTaskDialogFragment();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN );
transaction.add(android.R.id.content, newFragment).addToBackStack(null).commit();
}

android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context=".MainActivity"
tools:showIn="#layout/app_bar_main">
Then define it in onCreate of MainactivityClass
Like this
content = (ConstraintLayout)findViewById(R.id.content);
Then Remove
android.R.id.content, newFragment
Use it like this in addNewTask.
R.id.content, newFragment
private void addNewTask() {
FragmentManager fragmentManager = getSupportFragmentManager();
AddTaskDialogFragment newFragment = new AddTaskDialogFragment();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN );
transaction.add(R.id.content, newFragment).addToBackStack(null).commit();
}
you can see status bar.

ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this,mDrawerLayout, toolbar,R.string.app_name,
R.string.app_name);
mDrawerToggle.syncState();
//mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerLayout.addDrawerListener(mDrawerToggle);
}

In your My xml
Make xml for navigation drawer like this:
Make DrawerLayout as your parent Layout
<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"
tools:openDrawer="start">
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_home"
app:menu="#menu/activity_home_drawer" />
</android.support.v4.widget.DrawerLayout>

You have to put the drawer layout as the parent element, so your layout will become
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#71b6ca"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#71b6ca"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:title="DocVids"/>
<FrameLayout
android:id="#+id/containerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
</FrameLayout>
<android.support.design.widget.NavigationView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/mynav"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:layout_marginTop="-24dp"
app:menu="#menu/drawer"//Your drawer menu consisting of menu items
/>
</LinearLayout>
</android.support.v4.widget.DrawerLayout>

same navigation drawer in different activities, toolbar error

I'm trying to develop an app with multiple activities and the same navigation drawer and toolbar.
I've created a BaseActivity for initialization of drawer and other activities extend it, but I have problems with toolbar, in particular when using setSupportActionBar(toolbar).
How can I fix this problem?
BaseActivity.java
public abstract class BaseActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
private DrawerLayout drawer;
private ActionBarDrawerToggle toggle;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(getLayoutResourceId());
}
protected abstract int getLayoutResourceId();
public void initDrawer() {
drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
toggle = new ActionBarDrawerToggle(
(Activity) this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.setDrawerIndicatorEnabled(true);
toggle.syncState();
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.food) {
final Intent intent = new Intent(this, FoodDiary.class);
startActivity(intent);
}
drawer.closeDrawer(GravityCompat.START);
return true;
}

You can't use same Navigation Drawer and Toolbar with different Activities.
If you want different screens with the same components, you have to use Fragments with one Activity, for example FragmentActivity.

Recyclerview overlay toolbar

I use new com.android.support:design:22.2.0 library. When recyclerview initialised it overlay toolbar. I think it's because of incorrect initialization recyclerview. I else try insert recyclerview in single file, but i cannot understand how to inflate it
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
final ActionBar ab = getSupportActionBar();
if (ab != null) {
ab.setHomeAsUpIndicator(R.drawable.menu_and);
ab.setDisplayHomeAsUpEnabled(true);
}
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
if (navigationView != null) {
setupDrawerContent(navigationView);
}
lNews.clear();
populatedata();
mLinearLayoutManager = new LinearLayoutManager(getApplicationContext());
mRecyclerView = (RecyclerView)findViewById(R.id.recycleralda);
mRecyclerView.setLayoutManager(mLinearLayoutManager);
mRecyclerView.setItemAnimator(new DefaultItemAnimator());
mRecyclerviewAdapter = new RecyclerViewAdapter(getApplicationContext());
mRecyclerviewAdapter.loadNews(lNews);
mRecyclerView.setAdapter(mRecyclerviewAdapter);
