Change from drawer icon to arrow when using a NavigationView

I have an Activity that uses a NavigationView to display my app menu.
When menu opens and closes my App bar change from the drawer icon to the back arrow as expected.
I have a scenario, where i click on item 1 from my app menu, and it opens a fragment in my FrameLayout, and then i need to click a button that opens another fragment, replacing the previous one.
The app bar has the drawer icon in the 2 fragments, and i want to have a back arrow on the second fragment, so i can return to first fragment
Here is my MainActivity
public class MainActivity extends SuperActivity {
#BindView(R.id.nav_view) NavigationView navigationView;
#BindView(R.id.drawer_layout) DrawerLayout drawerLayout;
#BindView(R.id.container) FrameLayout frameLayout;

FragmentManager fragmentManager;
String activeName;
#Override

ButterKnife.bind(this);

}

}
setupDrawerContent(navigationView);
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override

create a global variable
private boolean isDrawerOpen = false;
then in your onOptionItemSelected do something like this
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id= item.getItemId();
if(id==android.R.id.home)
{
DrawerLayout drawerLayout = (DrawerLayout)findViewById(R.id.drawerlayout);
if(isDrawerOpen){
isDrawerOpen = false;
drawaerLayout.closeDrawer(GravityCompat.START);
} else{
isDrawerOpen = true;
drawaerLayout.openDrawer(GravityCompat.START);
}
return true;
}
if(id==R.id.action_settings){
Toast.makeText(this, "this is setting", Toast.LENGTH_SHORT).show();
}
if(id==R.id.action_mail){
startActivity(new Intent(this,SubActivity.class));
}
if(id==R.id.action_help){
Toast.makeText(this, "this is action_help", Toast.LENGTH_SHORT).show();
}
return true;
}

How to handle back arrow click?

I am developing an Android app about music. In this app, I have two fragments: PopFragment e GenresFragment.
In the XML file of PopFragment called fragment_pop.xml, I have toolbar with a back arrow that goes back to GenresFragment.
My toolbar code is this:
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
>
<include
android:layout_height="wrap_content"
android:layout_width="match_parent"
layout="#layout/toolbar_layout"
/>
</android.support.design.widget.AppBarLayout>
<ImageButton
android:id="#+id/arrowPop"
android:layout_width="54dp"
android:layout_height="wrap_content"
android:src="#drawable/ic_arrow_back_black_24dp"
style="?android:attr/borderlessButtonStyle"
/>
In the Java file of PopFragment called PopActivity, I have some code but it's not working.
I have this code:
public class PopActivity extends AppCompatActivity implements View.OnClickListener {
public PopActivity() {
// Required empty public constructor
}
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_pop);
Toolbar toolbar = (Toolbar)findViewById(R.id.toolBar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
ImageButton backBtn = (ImageButton)findViewById(R.id.arrowPop);
}
#Override
public void onClick (View view) {
Intent i = new Intent();
switch (view.getId()) {
case R.id.arrowPop:
break;
}
}
Can you help me please?
Thank you

Try something like:
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater){
inflater.inflate(R.menu.your_menu, menu);
}
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home: {
getActivity().onBackPressed();
break;
}
}
return true;
}

You generally don't need to add your own arrow icon, the Toolbar should be able to handle it for you.
if(shouldShowArrow()) {
drawerLayout.setDrawerLockMode(LOCK_MODE_LOCKED_CLOSED, GravityCompat.START);
drawerToggle.setDrawerIndicatorEnabled(false);
MyActivity.this.getSupportActionBar().setDisplayHomeAsUpEnabled(true);
} else { // hamburglar icon
drawerLayout.setDrawerLockMode(LOCK_MODE_UNLOCKED, GravityCompat.START);
MyActivity.this.getSupportActionBar().setDisplayHomeAsUpEnabled(false);
drawerToggle.setDrawerIndicatorEnabled(true);
}
drawerToggle.syncState();
And then you can define what happens when you click the arrow
#Override
protected void onCreate(Bundle bundle) {
super.onCreate(bundle);
ButterKnife.bind(this);
setSupportActionBar(toolbar);
ActionBar actionBar = getSupportActionBar();
drawerToggle = new ActionBarDrawerToggle(MyActivity.this, drawerLayout, toolbar, R.string.open, R.string.close) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
MyActivity.this.supportInvalidateOptionsMenu();
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
MyActivity.this.supportInvalidateOptionsMenu();
}
};
drawerLayout.setDrawerListener(drawerToggle);
drawerToggle.setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// what to do when you click the arrow
}
});
actionBar.setDisplayHomeAsUpEnabled(false);
actionBar.setHomeButtonEnabled(true);
}
#Override
protected void onPostCreate(Bundle bundle) {
super.onPostCreate(bundle);
drawerToggle.syncState();
}
#Override
protected void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
drawerToggle.onConfigurationChanged(newConfig);
}

Use the following code as a quick fix, which mimics the back button being pressed.
switch (view.getId()) {
case R.id.arrowPop:
onBackPressed();
break;
}
Using this code, you shouldn't have to define the back button in the toolbar yourself, Android will handle it.
Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
Then when you click the back button, Android will call onBackPressed() for you.

Cannot listen clicks on up caret

I've a single activity(MainActivity) which extends actionbaractivity and implements NavigationDrawer. I've setup the drawertoggle in the activity itself.
I'm creating new fragments from a fragment that was created by another fragment which is in turn created by the MainActivity. ( MainActivity -> HomeFragment ->AnotherFragment).
MainActivity.java
public class MainActivity extends ActionBarActivity implements FragmentDrawer.FragmentDrawerListener, TitleSetter, NavigationDrawerEnabler{
#Override

// 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.
/* This function is never called even if the Up caret button is pressed!! */
if (mDrawerToggle.isDrawerIndicatorEnabled() &&
mDrawerToggle.onOptionsItemSelected(item))
return true;
switch (item.getItemId()) {

I actually referred this tutorial to setup navigation drawer fragment : Android Hive.
I also referred similar questions answered here on stackoverflow :
1.Switching between Android Navigation Drawer image and Up caret when using fragments
2.My problem is similiar to this : Android Navigation Drawer Show Up Indicator for Lower Level Fragments.
- I couldn't comment here as i do not have 50 reps. I implemented what was exactly told in the comments.
But still clicking on the up caret doesn't run the function onOptionItemSelected, even though i've homebutton enabled.!
I'm now adding my custom styles.xml, may be some error in this?
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="MyMaterialTheme" parent="MyMaterialTheme.Base"></style>
<style name="MyMaterialTheme.Base" parent="Theme.AppCompat">
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="android:activatedBackgroundIndicator">#drawable/nav_background</item>
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="android:textColorPrimary">#color/textColorPrimary</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
</resources>
Also the custom toolbar.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
local:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
local:popupTheme="#style/ThemeOverlay.AppCompat.Light" />

SOLVED FINALLY
I figured out the problem, it is due to the custom toolbar that I used. When a custom toolbar is set up, we also have to set a listener on the up caret using the method called drawertoggler.setNaviagtionOnClickListener
In the onCreate() method of the activity we need to add the following code:
drawertoggler.setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getSupportFragmentManager().popBackStackImmediate();
}
});
Other cases like OnBackPressed can be handled by setting a OnStackChangeListener in the activity and make necessary changes. It is clearly explained here :#riwnodennyk.

Navigation Drawer in multiple activities does not work

I'm trying to use NavigationDrawer on my activity (Home), but the content of activity is not shown.
home_activity.xml
<LinearLayout 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"
android:orientation="vertical"
android:id="#+id/home_activity">
<Button
android:id="#+id/like_count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="likeCounter"
android:background="#drawable/likecountgreen" />
</LinearLayout>
activity_drawer.xml
<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" >
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<ListView
android:id="#+id/nav_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#fff"
android:choiceMode="singleChoice" />
HomeActivity.class
public class HomeActivity extends BaseActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home_activity);
super.onCreateDrawer();
}
}
BaseActivity.class
public class BaseActivity extends ActionBarActivity implements AdapterView.OnItemClickListener {
private ListView drawerList;
private DrawerLayout drawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
private String[] options;
private TextView titleActionBar;
protected void onCreateDrawer() {
setContentView(R.layout.activity_drawer);
setupActionBar();
options = getResources()
.getStringArray(R.array.drawer_options);
drawerLayout =
(DrawerLayout) findViewById(R.id.drawer_layout);
drawerList = (ListView) findViewById(R.id.nav_drawer);
drawerList.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, options));
drawerList.setOnItemClickListener(this);
setupDrawer();
}
private void setupActionBar() {
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setCustomView(R.layout.action_bar);
titleActionBar = (TextView) findViewById(R.id.title_action_bar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
private void setupDrawer() {
mDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, R.string.drawer_open, R.string.drawer_close) {
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
titleActionBar.setText("App");
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
titleActionBar.setText("Options");
invalidateOptionsMenu();
}
};
mDrawerToggle.setDrawerIndicatorEnabled(true);
drawerLayout.setDrawerListener(mDrawerToggle);
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
switch (position) {
case 2:
startActivity(new Intent(getApplicationContext(), LoginActivity.class));
overridePendingTransition(R.anim.abc_fade_in, R.anim.abc_fade_out);
drawerLayout.closeDrawer(drawerList);
break;
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.home_menu, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_search) {
return true;
}
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
}
What I've discovered is that drawer_activity is overlaying home_activity.
How can I solve it?

In onCreateDrawer you are setting a new layout, so your layout that you set in your MainActivity is not shown anymore. Here is how you can solve this:
HomeActivity:
public class HomeActivity extends BaseActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.onCreateDrawer(R.layout.home_activity);
}
}
And in your BaseActivity:
protected FrameLayout content;
protected void onCreateDrawer(final int layoutResID) {
setContentView(R.layout.activity_drawer);
content = (FrameLayout) findViewById(R.id.content_frame);
getLayoutInflater().inflate(layoutResID, content, true);
setupActionBar();
options = getResources()
.getStringArray(R.array.drawer_options);
drawerLayout =
(DrawerLayout) findViewById(R.id.drawer_layout);
drawerList = (ListView) findViewById(R.id.nav_drawer);
drawerList.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, options));
drawerList.setOnItemClickListener(this);
setupDrawer();
}
Now the FrameLayout in your activity_drawer layout contains the layout of your HomeActivity.
