new activity won't start after clicked navigation drawer - android

I am aware that this question exists but the answers don't work for my case.
I have a navigation drawer with four items, but when I click on the first one (the one i'm working on right now), the new activity I created doesn't open, I have looked and tried everything I found on the internet but nothing seems to work.
i'm kinda new to android studio so I really don't know how to fix this. The android studio version I am using is 3.0.
This is my menu xml:
<?xml version="1.0" encoding="utf-8"?>

<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/m1" android:title="Agora Mall"
android:icon="#drawable/ic_ammunition"/>
<item android:id="#+id/m2" android:title="Downtown Center"
android:icon="#drawable/ic_ammunition"/>
<item android:id="#+id/m3" android:title="Galeria 360"
android:icon="#drawable/ic_ammunition"/>
<item android:id="#+id/m4" android:title="Sambil"
android:icon="#drawable/ic_ammunition"/>
</menu>
this is the main activity class code:
package com.example.arlet.storemaps;
import android.content.Intent;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.MenuItem;
import android.view.Window;
public class MainActivity extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer);
mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.open, R.string.close);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(mToggle.onOptionsItemSelected(item)) {
return true;
}
switch(item.getItemId()){
case R.id.m1:
Intent intent = new Intent(MainActivity.this, AgoraActivity.class);
startActivity(intent);
return true;
}
return super.onOptionsItemSelected(item);
}
}

You must implement onNavigationItemSelected() for the navigation drawer menu.
onOptionsItemSelected() is related to the toolbar options menu items.
You can find all the necessary code for this if you create a new project and choose
Navigation Drawer Activity
as the type of your MainActivity.

You Can handle navigation drawer item click in following way:
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
// This method will trigger on item Click of navigation menu
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
//Check to see which item was being clicked and perform appropriate action
switch (menuItem.getItemId()) {
//Replacing the main content with ContentFragment Which is our Inbox View;
case R.id.m1:
Intent intent = new Intent(MainActivity.this, AgoraActivity.class);
startActivity(intent);
return true;
break;
case R.id.m2:
break;
case R.id.m3:
break;
case R.id.m4:
break;
}
menuItem.setChecked(true);
return true;
}
});

You must implement NavigationView.OnNavigationItemSelectedListener for the drawer items to work perfectly
Add this to your class declaration
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener{
// then overide this method to
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
switch(id){
case R.id.m1:
Intent intent = new Intent(MainActivity.this, AgoraActivity.class);
startActivity(intent);
return true;
//other cases goes here
}
return super.onOptionsItemSelected(item);
}
//you might want to ovewrite this method too
#Override
public void onBackPressed() {
if (mDrawerLayout.isDrawerOpen(GravityCompat.START)) {
mDrawerLayout.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}

Hey Guys I read this thread a while ago and tried to replicate it since i'm using multiple activities within my app.

It's working great up to the fact that when i click an item in the navigation nothing happens. Are there any suggestions to what I'm doing wrong.
You can find the whole project here.
Thanks for your help.
First , post a reference or code to how you are creating the menu item , do u create it in the resources menu file or simply load an array , If you are using array then i would suggest you to use menu xml to create menu items.
Something like this:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/new_game"
android:icon="#drawable/ic_new_game"
android:title="#string/new_game"
android:showAsAction="ifRoom"/>
<item android:id="#+id/help"
android:icon="#drawable/ic_help"
android:title="#string/help" />
</menu>
also make corresponding changes in ur code,check

Navigation drawer Fragment Issue

Hi i have this problem with my navigation drawer. The drawer opens fine but i am having problems with the onClickListener. if an item on the drawer is clicked on it doesnt show the related layout instaed a black page shows. Please help

You're not switching fragments correctly in your case statements. You're only instantiating a new Fragment class and not doing anything with it. You need to do something like this:
Fragment fragment;
switch (menuItem.getItemId()){
//Replacing the main content with ContentFragment Which is our Inbox View;
case R.id.dashboard:
Toast.makeText(getApplicationContext(),"dashboard",Toast.LENGTH_SHORT).show();
fragment = new Dashboard();
break;
// For rest of the options we just show a toast on click
case R.id.profile:
Toast.makeText(getApplicationContext(),"profile",Toast.LENGTH_SHORT).show();
fragment = new Profile();
break;
case R.id.logs:
Toast.makeText(getApplicationContext(),"logs",Toast.LENGTH_SHORT).show();
fragment = new Logs();
break;
case R.id.statements:
Toast.makeText(getApplicationContext(),"statements",Toast.LENGTH_SHORT).show();
fragment = new Statements();
break;
case R.id.timeline:
Toast.makeText(getApplicationContext(),"timeliine",Toast.LENGTH_SHORT).show();
fragment = new Timeline();
break;
case R.id.settings:
Toast.makeText(getApplicationContext(),"settings",Toast.LENGTH_SHORT).show();
fragment = new Settings();
break;
default:
Toast.makeText(getApplicationContext(),"Somethings Wrong",Toast.LENGTH_SHORT).show();
break;
}
android.support.v4.app.FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.frame,fragment);
fragmentTransaction.commit();
This way you're instantiating a fragment with a proper Fragment class each time, and at the end, replacing the frame with that particular fragment.
Digresion: It is recommended that you use newInstance to get the fragments and not the constructor. This is known as the Singleton design pattern.

how to change the main layout by SideMenu

about : I just click the menu SideMenu
"Rate" or even other menu, and I want to change the main view that the right arrow shows, but how? and here is the source of github
case 0:
// int the case, click the menu : Rate (or even other menu)
/**
* If I click the menu in the picture : Rate
* I want to change the main layout that the right arrow shows
* but how ?
* 1: what to do with the content view ?
* 2: or what to with the following code ?
*/
break;
You seem to have 2 options:
Intent to a new Activity which has your required functionality
Intent rateIntent = new Intent(CurrentActivity.this, NextActivity.class));
startActivity(rateIntent);
If you use fragments, you will need to replace your current fragment, you can use the FragmentManager for this type of app navigation
NextFragment nextFrag= new NextFragment();
this.getFragmentManager().beginTransaction()
.replace(R.id.Layout_container, nextFrag,TAG_FRAGMENT)
.addToBackStack(null)
.commit();

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 ?

Fragment Navigation Drawer

I read this post :
I try to do it but i have trouble in the "Navigating between Menu Items" section.
Where do the code of this section go ? In the MainActivity.java file or else?
When i paste it on my IDE (Android Studio 1.4) the items "nvDrawer" and "NavigationView" are red:
Also, i have two onCreate() on the same file.
Can you give me some suggestions how to make it work?
Below the code of my MainActivity.java.
package com.ther01s.android.ma0;
import android.os.Bundle;
import android.support.design.widget.NavigationView;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.view.GravityCompat;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.MenuItem;
public class MainActivity extends AppCompatActivity {
private DrawerLayout mDrawer;
private Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Set a Toolbar to replace the ActionBar.
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// Find our drawer view
mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// The action bar home/up action should open or close the drawer.
switch (item.getItemId()) {
case android.R.id.home:
mDrawer.openDrawer(GravityCompat.START);
return true;
}
return super.onOptionsItemSelected(item);
}
// Make sure this is the method with just `Bundle` as the signature
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
// Find our drawer view
nvDrawer = (NavigationView) findViewById(R.id.nvView);
// Setup drawer view
setupDrawerContent(nvDrawer);
}
private void setupDrawerContent(NavigationView navigationView) {
navigationView.setNavigationItemSelectedListener(
new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
selectDrawerItem(menuItem);
return true;
}
});
}
public void selectDrawerItem(MenuItem menuItem) {
// Create a new fragment and specify the planet to show based on
// position
Fragment fragment = null;
Class fragmentClass;
switch(menuItem.getItemId()) {
case R.id.nav_first_fragment:
fragmentClass = FirstFragment.class;
break;
default:
fragmentClass = FirstFragment.class;
}
try {
fragment = (Fragment) fragmentClass.newInstance();
} catch (Exception e) {
e.printStackTrace();
}
// Insert the fragment by replacing any existing fragment
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.flContent, fragment).commit();
// Highlight the selected item, update the title, and close the drawer
menuItem.setChecked(true);
setTitle(menuItem.getTitle());
mDrawer.closeDrawers();
}
}
Install latest android studio . then go to File --> New Project-->Configure your Project-->Target Device-->Choose Navigation Drawer Activity--> finish. You will get an awesome template from Android studio itself. Dont be confused by looking up for other useless tutorials.
