And also I need to make the toolbar transparent.I am using default navigation drawer activity.Can anyone help? Any help will be appreciated.

Hello Try this if it may help
1) Put this method in your activity
public void initToolBar(String title) {
toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle(title);
setSupportActionBar(toolbar);
toolbar.setNavigationIcon(R.mipmap.ic_launcher_round);
toolbar.setNavigationOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "clicking the toolbar!", Toast.LENGTH_SHORT).show();
}
}
);
}
2) To update the method from your fragment call mehtod using
((MainActivity) getActivity()).initToolBar("Fragment Title");

How to add image icons in material design navigation drawer?

I am following this example for navigation drawer. Now I am able to display text and I also set icons, but icon is not visible. Can any one help me with that? What is the issue with that code:

use this code to change navigation icon
drawerToggle.setDrawerIndicatorEnabled(false);
toolbar.setNavigationIcon(R.drawable.ic_nav);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
drawerLayout.openDrawer(Gravity.LEFT);
}
});
drawerToggle.syncState();

i hope this works for you. please change your setUp function like this.
public void setUp(int fragmentId, DrawerLayout drawerLayout, final Toolbar toolbar) {
containerView = getActivity().findViewById(fragmentId);
mDrawerLayout = drawerLayout;
//add here this code
toolbar.setNavigationIcon(R.drawable.iv_menu);
mDrawerToggle = new ActionBarDrawerToggle(getActivity(), drawerLayout, toolbar, R.string.drawer_open, R.string.drawer_close) {
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getActivity().invalidateOptionsMenu();
}
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
getActivity().invalidateOptionsMenu();
}
#Override
public void onDrawerSlide(View drawerView, float slideOffset) {
super.onDrawerSlide(drawerView, slideOffset);
toolbar.setAlpha(1 - slideOffset / 2);
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerLayout.post(new Runnable() {
#Override
public void run() {
mDrawerToggle.syncState();
}
});
}

Navigation Drawer not closing

I have implemented a navigationdrawer in android.I don't understand how to close the drawer when a item from the drawer list is selected.The foolowing code gives me a null pointer exception.
The mainactivity:
public class MainActivity extends ActionBarActivity {
String[] planet={"earth","mars","jupiter"};
ListView lv;
DrawerLayout mDrawerLayout;
NavigationDrawerFragment navigationDrawerFragment;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if(savedInstanceState==null){
earth earthfrag=new earth();
FragmentManager fragmentManager=getSupportFragmentManager();
FragmentTransaction transaction=fragmentManager.beginTransaction();
transaction.add(R.id.mainactivity,earthfrag,"earth").commit();
}
Toolbar toolbar = (Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(toolbar);
mDrawerLayout=(DrawerLayout)findViewById(R.id.nav_drawer);
navigationDrawerFragment = (NavigationDrawerFragment) getSupportFragmentManager().findFragmentById(R.id.drawer_fragment);
navigationDrawerFragment.setup(mDrawerLayout, toolbar);
lv= (ListView) findViewById(R.id.listView);
lv.setAdapter(new ArrayAdapter<String>(getApplicationContext(),android.R.layout.simple_list_item_1,planet));
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
FragmentManager fragmentManager=getSupportFragmentManager();
FragmentTransaction transaction=fragmentManager.beginTransaction();
if(position==2){
jupiter jupiterfrag=new jupiter();
transaction.replace(R.id.mainactivity, jupiterfrag, "jupiter").commit();
}
if (position==1){
mars marsfrag=new mars();
transaction.replace(R.id.mainactivity,marsfrag,"mars").commit();
}
if (position==0){
earth earthfrag=new earth();
transaction.replace(R.id.mainactivity,earthfrag,"earth").commit();
}
mDrawerLayout.closeDrawer(lv);
}
});
}
#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) {
// 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);
}
}
The NavigationDrawerFragment :
public class NavigationDrawerFragment extends Fragment {
private ActionBarDrawerToggle mActionBarDrawerToggle;
private DrawerLayout mDrawerLayout;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
return inflater.inflate(R.layout.drawer_fragment,container,false);
}
public void setup(DrawerLayout drawerLayout,Toolbar toolbar) {
mDrawerLayout=drawerLayout;
mActionBarDrawerToggle=new ActionBarDrawerToggle(getActivity(),mDrawerLayout,toolbar,R.string.drawer_open,R.string.drawer_close){
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
};
mDrawerLayout.setDrawerListener(mActionBarDrawerToggle);
mDrawerLayout.post(new Runnable() {
#Override
public void run() {
mActionBarDrawerToggle.syncState();
}
});
}
}
The activity_main.xml:
<?xml version="1.0"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/nav_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">
<include
android:id="#+id/app_bar"
layout="#layout/app_bar" />
<RelativeLayout
android:id="#+id/mainactivity"
android:layout_width="match_parent"
android:layout_height="match_parent"></RelativeLayout>
</LinearLayout>
<fragment
android:id="#+id/drawer_fragment"
android:name="com.example.joy.ecoapp.NavigationDrawerFragment"
android:layout_width="280dp"
android:layout_height="match_parent"
android:layout_gravity="start"
tools:layout="#layout/drawer_fragment" />
</android.support.v4.widget.DrawerLayout>

I believe you need to wrap the fragment in a container, e.g. a LinearLayout. Then use that container as the drawer:
<LinearLayout
android:id="#+id/lv_wrapper"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#android:color/background_light"
android:padding="5dp" >
<fragment
android:layout_height="match_parent"
android:layout_width="match_parent"
android:id="#+id/drawer_fragment"
tools:layout="#layout/drawer_fragment"
android:name="com.example.joy.ecoapp.NavigationDrawerFragment" />
</LinearLayout>
Then in your code instead of calling
mDrawerLayout.closeDrawer(lv);
call it with your new wrapper:
mDrawerLayout.closeDrawer(findViewById(R.id.lv_wrapper);

Android Navigation Drawer Content Frame Cannot be resolved

I am using the following code to implement a simple navigation drawer based on the sample given in the Android Developers site.
public class MainActivity extends ActionBarActivity {
Toolbar toolbar;
DrawerLayout mDrawerLayout;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
ListView mDrawerList;
private String[] mDrawerItems;
ActionBarDrawerToggle drawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
mDrawerItems = getResources().getStringArray(R.array.graph_array);
mDrawerList = (ListView) findViewById(R.id.list_view_drawer);
setSupportActionBar(toolbar);
mTitle = mDrawerTitle = getTitle();
toolbar.setNavigationIcon(R.drawable.ic_menu_white_24dp);
mDrawerLayout = (DrawerLayout) findViewById(R.id.navDrawer);
mDrawerLayout.setStatusBarBackgroundColor(getResources().getColor(R.color.primaryDark));
drawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.abc_action_bar_home_description, R.string.abc_action_bar_home_description) {
public void onDrawerClosed(View view) {
getSupportActionBar().setTitle(mTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerLayout.setDrawerListener(drawerToggle);
if (savedInstanceState == null) {
selectItem(0);
}
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mDrawerItems));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
}
private class DrawerItemClickListener implements ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
}
}
private void selectItem(int position) {
// update the main content by replacing fragments
//Fragment fragment = new PlanetFragment();
//Bundle args = new Bundle();
//args.putInt(PlanetFragment.ARG_PLANET_NUMBER, position);
//fragment.setArguments(args);
if (position == 0) {
Fragment frag1 = new Fragment1();
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, frag1).commit();
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
setTitle(mDrawerItems[position]);
mDrawerLayout.closeDrawer(mDrawerList);
} else if (position == 1) {
}
}
#Override

getSupportActionBar().setTitle(mTitle);
}
#Override

// Sync the toggle state after onRestoreInstanceState has occurred.
drawerToggle.syncState();
}
#Override

// Pass any configuration change to the drawer toggls
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) {
// 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);
}
public static class PlanetFragment extends Fragment {
public static final String ARG_PLANET_NUMBER = "planet_number";
public PlanetFragment() {
// Empty constructor required for fragment subclasses
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_planet, container, false);
int i = getArguments().getInt(ARG_PLANET_NUMBER);
String planet = getResources().getStringArray(R.array.graph_array)[i];
int imageId = getResources().getIdentifier(planet.toLowerCase(Locale.getDefault()),
"drawable", getActivity().getPackageName());
((ImageView) rootView.findViewById(R.id.image)).setImageResource(imageId);
getActivity().setTitle(planet);
return rootView;
}
}
}
But I get an error saying "content_frame cannot be resolved". How do I fix this ?

Change the id of the frame... its normally container... But change it to content_frame and you are good.

Showing Map in a Fragment

In my application i want to show google map in a Fragment. My activity class is given below.
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] mPlanetTitles;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTitle = mDrawerTitle = getTitle();
mPlanetTitles = getResources().getStringArray(R.array.planets_array);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow,
GravityCompat.START);
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mPlanetTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_launcher, R.string.app_name,
R.string.action_settings) {
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null) {
selectItem(0);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
menu.findItem(R.id.action_websearch).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
switch (item.getItemId()) {
case R.id.action_websearch:
Intent intent = new Intent(Intent.ACTION_WEB_SEARCH);
intent.putExtra(SearchManager.QUERY, getActionBar().getTitle());
if (intent.resolveActivity(getPackageManager()) != null) {
startActivity(intent);
} else {
Toast.makeText(this, "Nothing", Toast.LENGTH_LONG).show();
}
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private class DrawerItemClickListener implements
ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
selectItem(position);
}
}
private void selectItem(int position) {
onItemSelected(mPlanetTitles[position]);
mDrawerList.setItemChecked(position, true);
setTitle(mPlanetTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
}
#Override
public void setTitle(CharSequence title) {
mTitle = title;
getActionBar().setTitle(mTitle);
}
/**
* When using the ActionBarDrawerToggle, you must call it during
* onPostCreate() and onConfigurationChanged()...
*/
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
public void onItemSelected(String link) {
DetailFragment fragment = (DetailFragment) getFragmentManager()
.findFragmentById(R.id.detailFragment);
fragment.setText(link);
}
}
As shown in the code in the Activity i am using a DrawyerLayout inside that there are four items. When the user press the Item. I am showing Fragment where the MapFragment kept inside.
Please see the Main Xml layout file.
<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" />
<fragment
android:id="#+id/detailFragment"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="2"
class="com.example.mynavigation.DetailFragment"
android:visibility="invisible" >
</fragment>
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp" />
</android.support.v4.widget.DrawerLayout>
My Fragment Class.
public class DetailFragment extends Fragment {
GoogleMap map ;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
System.out.println("kkkkkkkkkkkk");
View view = inflater.inflate(R.layout.fragment_rssitem_detail,
container, true);
return view;
}
public void setText(String item) {
System.out.println("set Tewxt");
TextView view = (TextView) getView().findViewById(R.id.detailsText);
view.setText(item);
}
}
And the fragment_rssitem_detail.xml file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|center_vertical"
android:layout_marginTop="20dip"
android:text="Default Text"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="30dip" />
<FrameLayout
android:id="#+id/map_frame"
android:layout_width="fill_parent"
android:layout_height="match_parent" >
<fragment
android:id="#+id/map"
class="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="8dp" />
</FrameLayout>
<!-- <ListView
android:id="#+id/list_fragment"
android:name="com.myapp.ListFragment"
android:layout_width="wrap_content"
android:layout_height="fill_parent" /> -->
</LinearLayout>

Put only LinearLayout at where you want to put map in your xml and push map programatically as below:
private SupportMapFragment mapFragment;
mapFragment = new SupportMapFragment();
addFragment(lnrMap.getId(), mapFragment); //lnrMap is your LinearLayout from xml.
googleMap = mapFragment.getExtendedMap();
AddFragment Method(),Put this method in your DetailFragment class:
public void addFragment(int layoutId, Fragment fragment) {
FragmentManager fm = getChildFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(layoutId, fragment);
ft.commit();
}
