Linear Layout Cannot be cast to toolbar - java

I tried to add the shadow to toolbar following the method here https://stackoverflow.com/a/26904102/4273056
And it crashed on my device, these are the errors
I couldn't figure out how to post the code as the website keeps telling it is not formatted even after doing many things, so here is a paste bucket link..
The Errors are here,Click here
This is the toolbar layout
<LinearLayout

mNavigationDrawerFragment.setup(R.id.fragment_drawer, (DrawerLayout) findViewById(R.id.drawer), mToolbar);
}

return super.onCreateOptionsMenu(menu);
}

Toast.makeText(this, "Menu item selected -> " + position, Toast.LENGTH_SHORT).show();
}
#Override
public void onBackPressed() {
if (mNavigationDrawerFragment.isDrawerOpen())
mNavigationDrawerFragment.closeDrawer();
else
super.onBackPressed();
}
}
What should I do to get rid of these errors, please help

you need to change
mToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
to
mToolbar = (Toolbar) findViewById(R.id.tool_bar);

You should check in your activity_main.xml layout.
In this layout you are using an element (may be an include) with an
id ="toolbar_actionbar"
You have to change this id.

Your setContentView in onCreate is setting it to R.layout.navigation_drawer. You didn't provide an example of that, but instead provided an example of R.layout.fragment_main. I'm thinking you want that one to be your layout instead. So in onCreate in your activity set your content view to that layout instead:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
... // The rest of your code here
}

How to create an abstract activity class and extend it to all activities?

I have navigation drawer menu and 6 activities. I want to create an abstract activity class, and move all my drawer menu code to it, and then extend it.
This is my Main activity.java and my drawer's code in this activity.
public class MainActivity extends AppCompatActivity {
private Toolbar toolbar;
protected DrawerLayout drawerLayout;
NavigationView navigationView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
TextView tv = (TextView)findViewById(R.id.textView);
Typeface textfont = Typeface.createFromAsset(getAssets(),"fonts/B Roya_YasDL.com.ttf");
tv.setTypeface(textfont);
toolbar = (Toolbar) findViewById(R.id.toolbar);
drawerLayout = (DrawerLayout) findViewById(R.id.a1);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_more_vert_black_24dp);
navigationView = (NavigationView) findViewById(R.id.a2);
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
item.setChecked(true);
drawerLayout.closeDrawer(Gravity.RIGHT);
switch (item.getItemId()){
case R.id.intro:
Intent i = new Intent(MainActivity.this, IntroActivity.class);
startActivity(i);
break;
}
return false;
}
});
}
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.khat) {
if (drawerLayout.isDrawerOpen(Gravity.RIGHT)) {
drawerLayout.closeDrawer(Gravity.RIGHT);
}
else {
drawerLayout.openDrawer(Gravity.RIGHT);
}
return super.onOptionsItemSelected(item);
}
else {
Toast.makeText(getApplicationContext(),"somthing",Toast.LENGTH_LONG).show();
}
return true;
}
public void onBackPressed(){
if (drawerLayout.isDrawerOpen(Gravity.RIGHT)){
drawerLayout.closeDrawer(Gravity.RIGHT);
}else {super.onBackPressed();}
}
and this is my second activity for example:
public class IntroActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_intro);
}
How can I create an abstract activity class and insert my drawer's code in there and call it from any activity that I want?
You have to create mainActivity like
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener{
public NavigationView navigationView;
public DrawerLayout drawer;
public RelativeLayout content;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.setContentView(R.layout.activity_main);
drawer=(DrawerLayout) findViewById(R.id.drawer_layout);
content = (RelativeLayout) findViewById(R.id.content);
navigationView = (NavigationView)findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void setContentView(#LayoutRes int layoutResID) {
LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(layoutResID, null);
// var x = layout.LayoutParameters;
content.addView(layout);
}
public void OpenDrawer()
{
drawer.openDrawer(Gravity.START,true);
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()){
case R.id.navdrawer_item_first:
Toast.makeText(this, "first item clicked", Toast.LENGTH_SHORT).show();
break;
case R.id.navdrawer_item_second:
Toast.makeText(this, "second item clicked", Toast.LENGTH_SHORT).show();
break;
}
drawer.closeDrawers();
return true;
}
}
And activity_main
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:drawer="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/content" />
<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"
drawer:menu="#menu/navigation_drawer_items"
drawer:headerLayout="#layout/drawer_header"
android:background="#343a46"
drawer:itemTextColor="#ffffff" />
</android.support.v4.widget.DrawerLayout>
then you will extend Mail Activity
public class SecondActivity extends MainActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.setContentView(R.layout.activity_second);
}
}
and in Manifest make second activity is the launcher:
<activity android:name=".MainActivity">
</activity>
<activity android:name=".SecondActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>s
</activity>
I don't recommend making a abstract activity for this purpose.
Instead you should have just one activity where your navigation drawer is attached.And replace your activities with fragments except for MainActivity which would contain the navigation drawer.
activity_main layout would looks like:
-DrawerLayout
-FrameLayout
-NavigationView
And in the main activity whenever user clicks on any of the item in NavigationDrawer just replace the fragment with the required one.
navigation_drawer_items
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:id="#+id/group_feature"
android:checkableBehavior="single">
<item android:id="#+id/navdrawer_item_first"
android:title="first item"/>
<item android:id="#+id/navdrawer_item_second"
android:title="second item"/>
</group>
</menu>
drawer_header
<?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:background="#343a46"
android:orientation="vertical"
android:padding="10dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark">
<ImageView
android:id="#+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
/>
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:gravity="center_horizontal"
android:textColor="#dfba6b"
android:textStyle="bold" />
</LinearLayout>

Action bar missing when using TabLayout

I've implemented TabLayout from the support library, but it overwrites the ActionBar that i need.
This is the activity that sets it up and inflates the tabs and loads the fragment for the tab.
public class TabsActivity extends android.support.v4.app.FragmentActivity {
FloatingActionButton fab;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tabs);
setTitle("Fuel Logger");
ActionBar a = getActionBar();
ViewPager vp = (ViewPager) findViewById(R.id.viewpager);
vp.setAdapter(new FragmentPagerAdapter(
getSupportFragmentManager(), TabsActivity.this
));
TabLayout tabLayout = (TabLayout) findViewById(R.id.fuel_sliding_tabs);
tabLayout.setupWithViewPager(vp);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.fuel_menu, menu);
MenuItem refresh = menu.findItem(R.id.action_settings);
refresh.setEnabled(true);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
switch (id){
case R.id.action_settings:
break;
case R.id.action_favorite:
return true;
default:
}
return super.onOptionsItemSelected(item);
}
}
and the xml is just the view pager and tab layout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.TabLayout
style="#style/FuelTabLayout"
android:id="#+id/fuel_sliding_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="scrollable"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="0px"
android:layout_weight="1.27"
android:background="#android:color/white"
android:layout_alignParentBottom="true"
android:layout_below="#+id/fuel_sliding_tabs" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"
android:src="#android:drawable/ic_menu_set_as"
app:layout_anchorGravity="bottom|right|end"
app:backgroundTint="#color/colorAccent"
android:layout_gravity="right"
android:cropToPadding="true"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_marginRight="20dp"
android:layout_marginEnd="20dp"
android:layout_marginBottom="20dp" />
</RelativeLayout>
and an example of fragments code which is more or less the same for each fragments class
Public class SummaryFragment extends android.support.v4.app.Fragment {
public static final String ARG_PAGE = "SUMM_PAGE";
private int mTab;
public static SummaryFragment newInstance(int page){
Bundle args = new Bundle();
args.putInt(ARG_PAGE, page);
SummaryFragment frag = new SummaryFragment();
frag.setArguments(args);
return frag;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mTab = getArguments().getInt(ARG_PAGE);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_tab_summary, null);
return view;
}
first add ToolBar , and use LinearLayout witch have horizontal orientation
and set the in the style NoActionBar
hope its help you

I face this problem today.
I think it's probably your DrawerLayout is at the root view, and you set the width and height = "match_parent".
In Lolipop, the tool bar is popup , so it's clickable. But in KitKat or lower version, it will click on the DrawerLayout, not the toolbar(the toolbar is behind the DrawerLayout).
My solution is to set MarginTop = "?attr/actionBarSize" in DrawerLayout.
Hope it's will helps you thought it's has been a long while : )
You codes seem a mess, take a look at mine, it works very well.

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" />

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;
