Use Same DrawerLayout and ActionBar In All Activities In Android Studio

Use Same DrawerLayout and ActionBar In All Activities In Android Studio - android

In MainActivity, I've created a DrawerLayout and ActionBar. Is there any way to use that same Drawer and ActionBar in other activities without writing the same code again? Here's the code I'm using:
Main.xml:
<androidx.drawerlayout.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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<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="wrap_content"
android:background="#color/colorPrimary"
android:theme="#style/ThemeOverlay.AppCompat.ActionBar"
app:titleTextColor="#FFF"></androidx.appcompat.widget.Toolbar>
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="50dp"
android:background="#color/colorPrimary"
>
</androidx.constraintlayout.widget.ConstraintLayout>
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/homepage_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical"
></androidx.recyclerview.widget.RecyclerView>
</LinearLayout>
<com.google.android.material.navigation.NavigationView
android:id="#+id/main_nav"
android:layout_width="277dp"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/header"
app:menu="#menu/drawer_menu"></com.google.android.material.navigation.NavigationView>
</androidx.drawerlayout.widget.DrawerLayout>
Main Java (I've Removed The Extra Code [Non Drawer-Actionbar Code]):
DrawerLayout drawerLayout;
Toolbar toolbar;
TextView json;
RequestQueue requestQueue;
ActionBarDrawerToggle actionBarDrawerToggle;
private RequestQueue mqueue;
private RecyclerView recyclerView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mqueue = Volley.newRequestQueue(this);
setuptools();
setUpToolbar();
}
private void setUpToolbar()
{
drawerLayout = (DrawerLayout) findViewById(R.id.drawer);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.app_name,R.string.app_name) ;
drawerLayout.addDrawerListener(actionBarDrawerToggle);
actionBarDrawerToggle.syncState();
toolbar.setNavigationIcon(R.drawable.ic_menu);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.right_menu,menu);
final MenuItem awesomeMenuItem = menu.findItem(R.id.notification_iconmain);
View awesomeActionView = awesomeMenuItem.getActionView();
awesomeActionView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onOptionsItemSelected(awesomeMenuItem);
}
});
final TextView not_num = (TextView) menu.findItem(R.id.notification_iconmain).getActionView().findViewById(R.id.hotlist_hot);
String username = Settings.Secure.getString(getContentResolver(), Settings.Secure.ANDROID_ID);
String server_url = "https://google.com/api/notifications.php?username="+username;
JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, server_url, null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONArray jsonArray = response.getJSONArray("results");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject notification_numbers = jsonArray.getJSONObject(i);
String final_num = notification_numbers.getString("notifications");
if(final_num.equals("0")){
}else{
not_num.setVisibility(View.VISIBLE);
not_num.setText(final_num);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}
);
mqueue.add(request);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if(id == R.id.notification_iconmain){
Intent intent_noti = new Intent(this, NotificationsPage.class);
this.startActivity(intent_noti);
}
if(id == R.id.user_icon){
Intent intent_user = new Intent(this, Profile_Page.class);
this.startActivity(intent_user);
}
return super.onOptionsItemSelected(item);
}
}
What It Does:
It creates a slider drawer, an action bar with the right side menu, and displays the notification count on Bell Icon, and each item has its custom on-click event.
Now, how I can use the same drawer, action bar without writing the code again and again in each activity.

Displaying Fragments in My Application using 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.

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.

DrawerLayout NavigationView No drawer view found with gravity LEFT

I have implemented a drawer layout whereby when I click a navigation view item a tab layout opens up. The tablayout comes in fine but the problem is when i click the back button of the tab layout the application crashes with No drawer view found with gravity LEFT. Also I have noticed that there is a bit of a lag when the navigation drawer closes when the tab layout comes in, the drawer does not close smoothly.
Below is my java code and xml:

How can i it? tnx <3

put this line
startActivity(new Intent(getApplicationContext(), Recycler_Page.class));
in
private void setupDrawerContent(NavigationView navigationView)
so updated method is like:
private void setupDrawerContent(NavigationView navigationView) {
navigationView.setNavigationItemSelectedListener(
new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
menuItem.setChecked(true);
startActivity(new Intent(getApplicationContext(), Recycler_Page.class));
mDrawerLayout.closeDrawers();
return true;
}
});
}

Why android navigation drawer creating two headers?

I followed a tutorial to push facebook info from login into an activity with a navigation, then put the into on top, as shown, which, after days of altering code, I finally got it to work.
But now I cant get the original header to go away. I've tried changing every part of the code, but I always end up with all or nothing. I know two heads are better than one, but this is an exception to the rule.
Also, I guess I cant post images, so, the original header is on top, where it should be.
The new header with my facebook profile picture and info, is underneath that.
And below that, starts the navigation drawer menu.
public class HomeActivity extends AppCompatActivity

u have to pass the header view into
navigation_view.removeHeaderView(navigation_view.getHeaderView(0);
and not null
navigation_view.removeHeaderView(null);

when you add header using app:headerLayout="#layout/nav_header_home" just like below
<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" />
then no need to add header again from code
remove below lines from setNavigationHeader() method
navigation_view.removeHeaderView(null);
View header = LayoutInflater.from(this).inflate(R.layout.nav_header_home, null);
navigation_view.addHeaderView(header);
after remove method look like below
Edit /
public void setNavigationHeader(){
navigation_view = (NavigationView) findViewById(R.id.nav_view);
View header = LayoutInflater.from(this).inflate(R.layout.nav_header_home, null);
user_name = (TextView) navigation_view.findViewById(R.id.username);
user_picture = (ImageView) navigation_view.findViewById(R.id.profile_pic);
user_email = (TextView) navigation_view. findViewById(R.id.email);
}

Try this, It's workable and tested.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
navigationView.removeHeaderView(navigationView.getHeaderView(0));
View headerLayout = navigationView.inflateHeaderView(R.layout.nav_header_main);
ImageView user_dp = headerLayout.findViewById(R.id.user_dp);
TextView user_fullname = headerLayout.findViewById(R.id.user_fullname);
TextView user_email = headerLayout.findViewById(R.id.user_email);
user_dp.setBackgroundResource(R.drawable.user);
user_fullname.setText(fullName);
user_email.setText(uemail);
}

The ViewPager doesn't scroll at al after refreshing the data

I have an activity which has a coordinator layout with viewpager and CircularPager Indicator. I am trying to use MaterialRefreshLayout Library to do pull to refresh
The library can be found at Pull to refresh library
However, after I use pull to refresh my data, the viewpager just doesn't update the rest of the fragment and hence it dosn't scroll. Once I do background foreground it scrolls alright. Below is the Layout and activity

}
}
private void updateViewPager(){
mSectionPagerAdapter.setPagerItem(myMap);
mSectionPagerAdapter.notifyDataSetChanged();
mCartCountIndicator.notifyDataSetChanged();
mViewPager.invalidate();
}
}
Not Sure what am I doing wrong here. Appreciate any suggestion.

use
mViewPager.setOffscreenPageLimit(numberOfPages);

Okay, figured since it is the activity that is not being refreshed itself I tried this.onResume() in the refresh method once I do notifyDataSetChanged(). It works.
Not sure it is the cleanest solution though
