Android Navigation Draver - android

Can some one please tell me how to create activities to this MainActivity that the Navigation Drawer will be seen in all of them? I need to use this specific MainActivity code. I don't need to use fragments, just 3 simple activities will be added to this drawer.

} else if (id == R.id.nav_send) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
NavDrawer layout :
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item android:id="#+id/nav_ingredients" android:icon="#mipmap/ingredients"
android:title="#string/ingredients" />
<item android:id="#+id/nav_recepies" android:title="#string/recipies"
android:icon="#mipmap/recepies"
/>
<item android:id="#+id/nav_grocery_list" android:icon="#mipmap/list"
android:title="#string/grocery_list" />
</group>
<item android:title="Communicate">
<menu>
<item android:id="#+id/nav_share" android:icon="#android:drawable/ic_menu_share"
android:title="Share" />
<item android:id="#+id/nav_send" android:icon="#android:drawable/ic_menu_send"
android:title="Send" />
</menu>
</item>
</menu>

Here is a complete example using the official Android Design Library
Also, here is some basic training using fragments in case you are not familiar with them.

One way to go would be to have your activities extend MainActivity.
In the other activities, you don't call setContentView instead, do this:
View contentView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
contentView = inflater.inflate(R.layout.layout_for_the_activity, null, false);
mDrawer.addView(contentView, 0);
where mDrawer is defined in your MainActivity like this:
protected DrawerLayout mDrawer;
mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);
This is explained in more detail here

Navigation Drawer - Redirected Activity does not have Left Menu

Hello I want to create a click event with Navigation Drawer Activity in Android Studio. When I click Gallery in left menu I redirected it to Gallery activity with intent. It is okey it works but there is no left menu in Gallery activity. I want all redirected activities have left menu. How can I do this?

} else if (id == R.id.nav_send) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
I only changed this with adding intent line.Everything else is default code when I chose NavigationDrawerActivity.
public class GalleryActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gallery);
}
}

Yes you can do this with activities also.
As activities are little bit hard or heavy in case of loading view and staring screen. that's why fragments are mostly preferred way with navigation drawer.
You can do
Create Base activity which have drawer and extend that activity in rest of activities. you can check implementation here and here
2nd option can be create main activity with navigation drawer and in content part of that load all fragments from the menu. For that you can check here
Because your GalleryActivity has a different layout.
If you want to preserve everything but the content of the main window i suggest you to use a fragment for the gallery instead of an activity

How would I convert this activity to a Fragment?

Below is my Main Activity with Navigation drawer. However I've realised that for my Fragment Transaction, this cant be an activity it has to be a fragment. Is it possible to convert to a fragment or shall I start again..

Cannot resolve Method 'replace (int)' for Fragment

im using the Navigation Drawer Activity and im stucked at one problem. I get this error message
Cannot resolve Method 'replace (int)
I was watching a tutorial but the guy doesnt get the error message somehow. I was also trying to solve the problem by reading other posts but it confused me even more.
My Code looks like this:
MainActivity.java
package androfenix.mycvapp;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;

setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);

this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();

navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.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
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_aboutme) {
FragmentAboutme fragmentAboutme = new FragmentAboutme();
FragmentManager manager = getSupportFragmentManager();
manager.beginTransaction().replace(R.id.relativelayout_for_fragment).commit(fragmentAboutme);
} else if (id == R.id.nav_cv) {
} else if (id == R.id.nav_skills) {
} else if (id == R.id.nav_projects) {
} else if (id == R.id.nav_download) {
} else if (id == R.id.nav_website) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
And the layout fragment which i want to replace is this one:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 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/relativelayout_for_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="androfenix.mycvapp.MainActivity"
tools:showIn="#layout/app_bar_main">
</android.support.constraint.ConstraintLayout>
Please Study about fragments
replace(R.id.relativelayout_for_fragment,"your about me fragment").commit();
why would you even pass fragment object in commit() method there is no such method;
Here FragmentTransaction.Commit() does not Require an Arguement
so instead of:
manager.beginTransaction().replace(R.id.relativelayout_for_fragment).commit(fragmentAboutme);
use:
manager.beginTransaction().replace(R.id.relativelayout_for_fragment, fragmentAboutme).commit();
Also make sure your FragmentAboutme is extending the support library
import android.support.v4.app.Fragment;

Navigation Drawer for Multiple activities

Hello i am new to android. I would like to implement navigation drawer consisting of a list of items, which when clicked opens a new activity. Basically a navigation drawer across all the activities. When I select an item from the navigation drawer that particular activity opens but the icon for the navigation drawer (hamburger icon) disappears. How do I get that?

It is advised to use Navigation Drawer with fragments as it will maintain the nav drawer. You have to convert your activities in fragments. Please check developer link- http://developer.android.com/training/implementing-navigation/nav-drawer.html
Has anyone figured out how to get this method of one main activity pushing in fragments to work with the back button ?
Everything works fine going "forward", and all the fragments get pulled into the content frame, but as soon as you hit the back button, the application closes...most likely because it is the only activity running and the back button closes the activity.
Anyway to put code in to get the fragment manager to go back to the last fragment and not close the activity on the back button ?
