How to Display Fragments in Main Activity from Navigation Drawer?

I have three Fragments that I am trying to display by clicking the appropriate option from a Navigation Drawer. I have the Navigation Drawer displaying and opening/closing fine. But I can't get any of the Fragments to display in the Activity. The main screen just stays blank whenever I click an option. There are no compilation errors. I am new to Android development and also Java dev, and I've been trying to complete this project for a month so it will be finished as soon as I can get this to work. You may see some instances of redundant code, because I just wanted to try anything that could work and I am not sure what to delete, so any clarification on that would help too.
The Fragments should be displayed as results in a RecyclerView.
MainActivity:
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
private DrawerLayout mDrawer;
private Toolbar toolbar;
private NavigationView nView;
private ActionBarDrawerToggle toggle;
private RequestQueue queue;

private RecyclerView atmView;
private AtmRecyclerViewAdapter atmRecyclerViewAdapter;

// Set a Toolbar to replace the ActionBar.
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// Find drawer layout
mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);
// Find drawer view
nView = (NavigationView) findViewById(R.id.nav_view);
// Set up drawer view
setupDrawerContent(nView);
// Not sure what this does
nView.setNavigationItemSelectedListener(this);
toggle = new ActionBarDrawerToggle(
this, mDrawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
// Tie DrawerLayout events to the ActionBarDrawerToggle
mDrawer.addDrawerListener(toggle);

I have two other Fragments that I set up a little differently but just showing the one for ATMs because I feel it is the closest to working. I appreciate the time and help any of the experienced programmers here can give me. If there is any more information that I should provide to help my situation, let me know. Thank you

How can i setup a base drawer for all activities

I have read a lot of answers here but could not manage to do it. I want all of my activities to have a drawer. Inside the drawer i have a ListView which contains all of the activities that the drawer should open. This is the implementation of the drawer:
public abstract class DrawerActivity extends BaseActivity {
private DrawerLayout drawerLayout;
private ListView drawerList;
private ActionBarDrawerToggle drawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.base_drawer_layout);
drawerLayout = findViewById(R.id.drawer_layout);
drawerList = findViewById(R.id.left_drawer);
final ArrayList<String> elements = new ArrayList<>();
elements.add("My tasks");
elements.add("Issues");
drawerList.setAdapter(new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, elements));
drawerList.setOnItemClickListener(createOnDrawerItemClickListener());
// enable ActionBar app icon to behave as action to toggle nav drawer
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
// ActionBarDrawerToggle ties together the the proper interactions
// between the sliding drawer and the action bar app icon
drawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
drawerLayout, /* DrawerLayout object */
R.string.drawer_open, /* "open drawer" description for accessibility */
R.string.drawer_close /* "close drawer" description for accessibility */
) {
public void onDrawerClosed(View view)
{
getSupportActionBar().setTitle("TITLE");
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView)
{
getSupportActionBar().setTitle("Title");
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
drawerLayout.addDrawerListener(drawerToggle);
}
/**
* When using the ActionBarDrawerToggle, you must call it during
* onPostCreate() and onConfigurationChanged()...
*/
#Override
protected void onPostCreate(Bundle savedInstanceState)
{
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
drawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggles
drawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
if (drawerToggle.onOptionsItemSelected(item))
return true;
return super.onOptionsItemSelected(item);
}
protected abstract DrawerItemClickListener createOnDrawerItemClickListener();
protected ListView drawerList()
{
return drawerList;
}
protected DrawerLayout drawerLayout()
{
return drawerLayout;
}
}
This is the drawer layout xml file
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.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">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#274"/>
</android.support.v4.widget.DrawerLayout>
Lets say i have currently two activities, My Tasks and Issues and both of them extend DrawerActivity. If i am in the Issues activity, how can i open the My Tasks activity through that drawer?
All activities that extend DrawerActivity implements createOnDrawerItemClickListener() which inside creates a new fragment with the layout of the the activity that implements DrawerActivity, which i'm pretty sure is wrong.
Example implementation:
#Override
protected DrawerItemClickListener createOnDrawerItemClickListener()
{
return new DrawerItemClickListener(position ->
{
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, new TaskFragment()).commit();
drawerList().setItemChecked(position, true);
drawerLayout().closeDrawer(drawerList());
});
}
And the DrawerItemClickListener:
public class DrawerItemClickListener implements ListView.OnItemClickListener {
private FragmentStrategy fragmentStrategy;
public DrawerItemClickListener(final FragmentStrategy fragmentStrategy)
{
this.fragmentStrategy = fragmentStrategy;
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
fragmentStrategy.showFragment(position);
}
public interface FragmentStrategy {
void showFragment(final int position);
}
}
How can i make this work?

In your case adding fragment will be the best solution.
create a fragment BlankFragment.java
public class BlankFragment extends Fragment {
public BlankFragment() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_blank, container, false);
}
}
and create fragment_black.xml
<FrameLayout 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="com.above_inc.shyam.drawer.BlankFragment">
<!-- TODO: Update blank fragment layout -->
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="#string/hello_blank_fragment" />
</FrameLayout>
now replace your method
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
Fragment fragment = null;
if (id == R.id.nav_camera) {
// Handle the camera action
fragment = new BlankFragment();
} else if (id == R.id.nav_gallery) {
} else if (id == R.id.nav_slideshow) {
} else if (id == R.id.nav_manage) {
} else if (id == R.id.nav_share) {
} else if (id == R.id.nav_send) {
}
if (fragment != null) {
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frame_container, fragment).commit();
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
add below code in your content_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.above_inc.shyam.drawer.MainActivity"
tools:showIn="#layout/app_bar_main">
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</RelativeLayout>
you can also add more fragment to other options same as camera in above code

Please help me to add the image, two text views near image, horizontal line, and the edit text. Thanks in advance

In your MainActivity, add a new field for the LinearLayout, and assign value to it in onCreate()
private LinearLayout mLenear;
mLenear = (LinearLayout)findViewById(R.id.left_drawer);// inside onCreate
Then add following code inside onPrepareOptionsMenu
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
// if nav drawer is opened, hide the action items
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mLenear);
menu.findItem(R.id.action_settings).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
Then change your closeDrawer like this.
mDrawerLayout.closeDrawer(mLenear);
This should resolve your issue. :)

this will be the main layout that you will be using it contain two parts one is the main part which will have the layout of the main screen and the drawer_layout is the layout that has you navigation view layouts
So you will have to create drawer_layout as you want to display and just simply call it here
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/navigationDrawer"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/mainLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
// you will have layout that you will use for your main activity or the activity where you are showing your navigation View
</FrameLayout>
// the drawer_layout will define your navigation View
<include layout="#layout/drawer_layout" />
</android.support.v4.widget.DrawerLayout>
In the activity you will get access to your drawer_layout and get access to your views using that object like
DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.navigationDrawer);
// Example of getting your view object
ImageView yourImageView = (ImageView) drawerLayout.findViewById(R.id.imageView);
// you can access any your drawerView using that drawerLayout object

android.support.v4.widget.DrawerLayout cannot be cast to android.support.v4.widget.DrawerLayout$DrawerListener

I am getting a DrawerLayout cannot be cast, So display an error and my apps is crashes.
I am a new android developer, help me out.
Here is My MainAvtivity:
public class MainActivity extends AppCompatActivity {
private Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
NavigationDrawerFragment drawerFragment = (NavigationDrawerFragment)
getSupportFragmentManager().findFragmentById(R.id.fragment_navigation_drawer);
drawerFragment.setUp((DrawerLayout) findViewById(R.id.drawer_layout),toolbar);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement

return true;

I follow slidenerd material Design Tutorials.

You need to make your code changes below:
// Set the drawer toggle as the DrawerListener
mDrawerLayout.setDrawerListener(mDrawerToggle);

The problem is in this line: mDrawerLayout.setDrawerListener((DrawerListener) mDrawerLayout); You need to set a listener, but you are type casting a DrawerLayout to a DrawerListener.
I suggest you remove that line totally, since it's not needed. If you really want to set a listener, you should do it as below:
mDrawerLayout.setDrawerListener(new DrawerLayout.DrawerListener() {
#Override
public void onDrawerSlide(View drawerView, float slideOffset) {
}
#Override
public void onDrawerOpened(View drawerView) {
}
#Override
public void onDrawerClosed(View drawerView) {
}
#Override
public void onDrawerStateChanged(int newState) {
}
});

Navigation Drawer is not opening on clicking menu icon

Navigation Drawer is not opening on clicking navigation icon(i.e 3 horizontal line on top left screen). On Lollipop it is working, but the problem is with Kitkat and jelly bean it is not working?

I face this problem today.
I think it's probably your DrawerLayout is at the root view, and you set the width and height = "match_parent".
In Lolipop, the tool bar is popup , so it's clickable. But in KitKat or lower version, it will click on the DrawerLayout, not the toolbar(the toolbar is behind the DrawerLayout).
My solution is to set MarginTop = "?attr/actionBarSize" in DrawerLayout.
Hope it's will helps you thought it's has been a long while : )

You codes seem a mess, take a look at mine, it works very well.
