Changing navigation view header image programmatically is not working

Changing navigation view header image programmatically is not working - java

I'm trying to change the Navigation view's header image on clicking drawer menu icon programmatically but now working.
How to solve this problem?
Here's my DrawerActivity class`
public class DrawerActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_drawer);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(120, 120);
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);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
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.drawer, 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_camera) {
// Handle the camera action
} 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) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
Here's my AriesActivity , on which I'm using drawer menu icon, on clicking drawer has been opened.
public class AriesActivity extends AppCompatActivity {
Toolbar mtoolbar;
private DrawerLayout drawerLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_aries);
//setting TOOLBAR on this activity(page)
mtoolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(mtoolbar);
Objects.requireNonNull(getSupportActionBar()).setTitle(null);
//setting DRAWER on this activity(page)
drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawerLayout, mtoolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawerLayout.addDrawerListener(toggle);
toggle.syncState();
}
Here's my navigation_view.xml layout file`
<android.support.design.widget.NavigationView android:layout_width="wrap_content"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/nav_view"
android:layout_gravity="start"
app:headerLayout="#layout/nav_header_drawer"
app:menu="#menu/activity_drawer_drawer"
xmlns:android="http://schemas.android.com/apk/res/android"
/>
and finally nav_view_header.xml layout file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:theme="#style/ThemeOverlay.AppCompat.Dark"
android:id="#+id/headerView">
<ImageView
android:id="#+id/imageViewNav"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_gravity="center"
android:layout_marginBottom="5dp"
android:background="#drawable/border_ring_shape"
android:contentDescription="#string/nav_header_desc"

android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="#string/sign_name"

android:textSize="20sp" />
</LinearLayout>

Add prefix of NavigationView before findviewByid or;
View header = mNavigationView.getHeaderView(0);
myImageView = (ImageView) header.findViewById(R.id.imageviewname);
myImageView.setBackground(ContextCompat.getDrawable(this, R.drawable.your_drawable));

Is there a reason you are using a FragmentTransaction? You could call
viewPager.setCurrentItem(0);
The argument you pass (0 or 1 or 2 or ...) is based on which action you click in the NavigationView. The tabs should update automatically when the ViewPager changes.

No error stated, though my startActivity(toy); does not open the new activity

This code does not open the second activity from the press of the button(it animated and pushes down when i press it), there are no errors in the build or app terminations. i am unsure where i have gone wrong as i have used the exact intent before on another app.
any help would be great!!!

How to share the NavigationView between activities in Android (SDK21+)

So, basically I have this class, the HomeActivity.class:
import android.content.Intent;
import android.os.Bundle;
import android.support.design.widget.NavigationView;
import android.support.v4.view.GravityCompat;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
public class HomeActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_drawer);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
/* TODO: Relocate this button to appear in each individual place
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.new_ticket);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "New ticket function here", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
*/
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);

}

}

}
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_home) {
} else if (id == R.id.nav_places) {
// Create SB to hold the places data
final StringBuilder apiPlacesInfo = new StringBuilder();
// Create new intent

// Get all available places from the API
new Thread(new Runnable() {

}
}).start();
// Parse the info
Place[] places = DataParser.ParsePlaces(apiPlacesInfo.toString());
// Put the extras to get on the next activity

// Start the new activity
startActivity(i);
} else if (id == R.id.nav_slideshow) {

} else if (id == R.id.nav_send) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
And this is my activity_drawer.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout

android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include
layout="#layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<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_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
And I also have the items listed in an .xml:
<group android:checkableBehavior="single">
<item
android:id="#+id/nav_home"
android:icon="#drawable/ic_menu_home"
android:title="#string/menu_home"
android:checked="true"/>
<item
android:id="#+id/nav_places"
android:icon="#drawable/ic_menu_places"
android:title="#string/menu_places" />
<item
android:id="#+id/nav_slideshow"
android:icon="#drawable/ic_menu_slideshow"
android:title="Option 3" />
<item
android:id="#+id/nav_manage"
android:icon="#drawable/ic_menu_manage"
android:title="Option 4" />
</group>
<item android:title="Separator 1">
<menu>
<item
android:id="#+id/nav_share"
android:icon="#drawable/ic_menu_share"
android:title="Option 1" />
<item
android:id="#+id/nav_send"
android:icon="#drawable/ic_menu_send"
android:title="Option 2" />
</menu>
</item>
</menu>
Basically most of it was generated by AndroidStudio.
I now want to create a new activity -> PlacesActivity and whenever I press "Places" on the navView, starting that activity. All is good for now, the problem is I can't seem to be able to "share" the navigationView between both activities.
I've been at it for 3 hours: Nothing on those other similar questions worked. I tried extending the PlacesActivity with HomeActivity and it worked only partially (it wouldn't show the proper content and even then, I had to copy code from the HomeActivity class).
What's the best way to go about this?
Thanks!

Navigation Drawer open a new Fragment

I open a new Android Studio project with a Navigation Drawer Activity. So there are activty_main.xml, app_bar_main.xml, content_main.xml and a nav_header_main.xml in the layout-folder and a Java-Class MainActivity.
When an item in the Navigation Drawer is used, should open a new fragment. In the fragment have to be the Navigation Drawer too. How can I this avaible to API 8. How can I do this? How open a new Fragment?

Sorry for my english and thanks for your help!

Here's how I implemented this in one of my own solutions, just switch values where appropriate:
mNavigationView = (NavigationView) (findViewById(R.id.nav_menu));
mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem item) {
switch(item.getItemId())
{
case R.id.menuEvents:
{
mFragmentTransaction = getSupportFragmentManager().beginTransaction();
mFragmentTransaction.replace(R.id.main_fragment, new eventFragment());
mFragmentTransaction.commit();
getSupportActionBar().setTitle("Upcoming Events");
//item.setChecked(true);
mDrawerLayout.closeDrawers();
break;
}
case R.id.menuTechnique:
{
mFragmentTransaction = getSupportFragmentManager().beginTransaction();
mFragmentTransaction.replace(R.id.main_fragment, new techniqueFragment());
mFragmentTransaction.commit();
getSupportActionBar().setTitle("Useful Techniques");
//item.setChecked(true);
mDrawerLayout.closeDrawers();
break;
}
case R.id.menuLink:
{
mFragmentTransaction = getSupportFragmentManager().beginTransaction();
mFragmentTransaction.replace(R.id.main_fragment, new linkFragment());
mFragmentTransaction.commit();
getSupportActionBar().setTitle("Helpful Links");
//item.setChecked(true);
mDrawerLayout.closeDrawers();
break;
}
case R.id.menuSettings:
{
mFragmentTransaction = getSupportFragmentManager().beginTransaction();
mFragmentTransaction.replace(R.id.main_fragment, new settingFragment());
mFragmentTransaction.commit();
getSupportActionBar().setTitle("Settings");
//item.setChecked(true);
mDrawerLayout.closeDrawers();
break;
}
}
return true;
}
});

how to include items in navigation drawer

Here is MainActivity.java
public class MainActivity extends ActionBarActivity {
// inisiasi toolbar
private Toolbar toolbar;
// navigation drawer
private DrawerLayout drawerLayout;
private ActionBarDrawerToggle drawerToggle;
String title = "My App";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
if (toolbar != null) {
toolbar.setTitle(title);
setSupportActionBar(toolbar);
}
initDrawer();
}
/**
* init navigation drawer thing
*/
private void initDrawer() {
//setup navigation drawer
drawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.txt_open, R.string.txt_close) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
// when drawer closed
toolbar.setTitle(title);
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
// when drawer open
toolbar.setTitle("Nav menu");
}
};
// setDrawerlisterner
drawerLayout.setDrawerListener(drawerToggle);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
drawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
drawerToggle.onConfigurationChanged(newConfig);
}
#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) {
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
if (drawerToggle.onOptionsItemSelected(item))
return true;
return super.onOptionsItemSelected(item);
}
}
and here is xml file layout view
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent"
tools:context=".MainActivity">
<!-- Toolbar -->
<include layout="#layout/toolbar" />
<!-- content -->
<android.support.v4.widget.DrawerLayout
android:layout_width="match_parent"
android:id="#+id/drawerLayout"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:background="#fff"
android:layout_height="match_parent">
<TextView
android:layout_centerInParent="true"
android:layout_width="wrap_content"
android:textColor="#000"
android:text="Our Content"
android:layout_height="wrap_content" />
</RelativeLayout>
<!-- nav drawer -->
<LinearLayout
android:layout_gravity="start"
android:orientation="vertical"
android:background="#fff"
android:layout_width="280dp"
android:layout_height="match_parent">
<TextView

android:layout_height="wrap_content" />
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
Does anyone know how to add a listview to navigation drawer. And i want to load a web page when user selects each item on navigation drawer into a fragment. I tried to implement a code from a sample but comes up with so many errors.

Well, there is nothing to afraid about NavigationDrawer. At first we may think that it is some special kind of activity and this and that. but it is so much simple.
Step 1 - Create xml file with 2 layouts
<FrameLayout>
//main screen contents
</FrameLayout>
<Linear/Relative/ListView/xyz>
// any layout that u want to be shown in navigation drawer
</Linear/Relative/ListView/xyz>
Step 2 - Define ur drawer in activity class with couple of codes
drawerLayout = (DrawerLayout) findViewById(R.id.NvDrawer);
drawerToggle = new ActionBarDrawerToggle(this, drawerLayout,
R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close);
drawerLayout.setDrawerListener(drawerToggle);
and override this methods
#Override
public void onDrawerSlide(View view, float v) {
}
#Override
public void onDrawerOpened(View view) {
}
#Override
public void onDrawerClosed(View view) {
}
#Override
public void onDrawerStateChanged(int i) {
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
drawerToggle.syncState();
}
Step 3 - Add this code in onOptionsItemSelected
if (drawerToggle.onOptionsItemSelected(item)) {
return true;
