also try to change AppCompatActivity to FragmentActivity. Before that i'am using SupportMapFragment and have same error. What wrong?

I also experience the same(which was no problem previously). Workaround is to add following flag to your MapActivity in your AndroidManifest.xml file
android:hardwareAccelerated="true"

android.view.InflateException: Binary XML file line #14: Error inflating class fragment

I am facing some problem when I click the back button and go back to the location fragment, I got an error below:

I did checked many post and tried all solutions, but its not working. It seems that other menu item is not a problem, Only this location page gives an error.
fragment_location.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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">
<Spinner
android:id="#+id/spinner1"
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="#color/white"
android:spinnerMode="dropdown"/>
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="40dp"/>
</RelativeLayout>
LocationFragment.java
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
view = inflater.inflate(R.layout.fragment_location, container, false);// this is the line 73
SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
return view;
}

Try to remove your mapFragment on onDestroyView in LocationFragment.java.
#Override
public void onDestroyView() {
super.onDestroyView();
SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map);
if (mapFragment != null)
getChildFragmentManager().beginTransaction().remove(mapFragment).commitAllowingStateLoss();
}

I think the main reason is this you use name instead of class,
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />
Try updating around this code base.
FragmentManager fmanager = getSupportFragmentManager();
Fragment fragment = fmanager.findFragmentById(R.id.map);
SupportMapFragment supportmapfragment = (SupportMapFragment)fragment;
GoogleMap supportMap = supportmapfragment.getMap()
You are using childSupportmanager , also this line view = inflater.inflate(R.layout.fragment_location, container, false); you never anchored your map view from it, example view.findViewVyId you never did that

Error inflating class android.support.v7.app.AlertController.RecycleListView

plz help me out what's the error and how to handle two fragment with two recyclerview in one activity.
THANK YOU for your concern!

android.support.v7.widget.RecyclerView
use this code in your xml file to create a listview. Simple!

You probably want to use android.support.v7.widget.RecyclerView.
Additional info that you don't need to know
RecycleListView is a nested class of android.support.v7.app.AlertController. One would refer to it as android.support.v7.app.AlertController$RecycleListView (the dollar sign). This is why it crashed at this point.
RecycleListView extends ListView not RecyclerView. That's why it would later crash with ClassCastException when you would try to use it in Java.
RecycleListView is an internal class of appcompat-v7 not to be used in your project.

I made the same mistake. Try to replace
android.support.v7.app.AlertController.RecycleListView
with
android.support.v7.widget.RecyclerView

Binary XML file line #13: Binary XML file line #13: Error inflating class fragment

I am noticing an issue with inflating the initial fragment via XML. What I am noticing is that the onPause(), onDestroy() lifecycle methods are not being called properly. If I replace this fragment, everything works fine. The issue is only when the app is first launched and the initial fragment is inflated via XML. To avoid this conflict I tried to launch the initial fragment programmatically but I keep receiving an inflating class error.

Here is how I am inflating my initial fragment via XML. In the Activity that is first launched, I added this segment of code to its layout
<fragment
android:id="#+id/frag_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.example.fragments.MainFragment" />
When I change fragments, such as clicking on a tab I replace the fragment using the following method
public void addFragmentReplace(int containerId, Fragment fragment) {
// check if the fragment has been added already
Fragment temp = mFragmentManager.findFragmentByTag(fragment.getClass().getSimpleName());
if (!Utils.checkIfNull(temp) && temp.isAdded()) {
return;
}
// replace fragment and transition with animation
try {
if (!Utils.isStringEmpty(getTopFragment().getTag()) && getTopFragment().isAdded()) {
// pop back stack
popBackStack();
}
mFragmentManager.beginTransaction().replace(containerId, fragment,
fragment.getClass().getSimpleName()).addToBackStack(null).commit();
} catch (IllegalStateException e) {
e.printStackTrace();
mFragmentManager.beginTransaction().replace(containerId, fragment,
fragment.getClass().getSimpleName()).addToBackStack(null)
.commitAllowingStateLoss(); // used as last resort
}
}
After changing tabs the fragment lifecycle works perfectly. Even when returning to the original tab. But how do I get the lifecycle to work initially when the fragment is inflated via XML or how can I remove the class property from XML and just add the fragment?
Adding a fragment in the Activity that is initially launched causes the inflate error. This is how I was adding the fragment, using the following method
public void addFragment(int containerId, Fragment fragment) {
// check if the fragment has been added already
Fragment temp = mFragmentManager.findFragmentByTag(fragment.getClass().getSimpleName());
if (!Utils.checkIfNull(temp) && temp.isAdded()) {
return;
}
// add fragment and transition with animation
mFragmentManager.beginTransaction().add(containerId, fragment,
fragment.getClass().getSimpleName()).addToBackStack(null).commit();
}
Thank you in advance!

scrollView in android with a class extending View class

i am not using any layout so the all view is created by drawView class then how can i use scrollView in this scenario. so that i can able to scroll and view the whole line.
MainActivity.java
public class MainActivity extends AppCompatActivity {
DrawView drawView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
drawView = new DrawView(this);
drawView.setBackgroundColor(Color.WHITE);
setContentView(drawView);
}
}
//this class will draw lines on screen.
public class DrawView extends View {
Paint paint = new Paint();
Bitmap bmp;
public DrawView(Context context) {
super(context);
paint.setColor(Color.BLACK);
paint.setStrokeWidth(3f);
bmp = BitmapFactory.decodeResource(getResources(), R.drawable.station);
}
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
canvas.drawLine(350,300,350,2500, paint);
for (int i = 315; i< 995;i=i+20)
canvas.drawLine(350,i,370,i,paint);
canvas.drawLine(370,300,370,2500, paint);
canvas.drawBitmap(bmp,350,300,paint);
canvas.drawBitmap(bmp,300,500,paint);
}
}
//I also tried like this
and when using this xml layout in that condition i have used
setContentView(R.layout.activity_main)
activity_main this is my xml layout file
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="true">
<com.example.shailendra.myapplication.DrawView
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</ScrollView>
Then i got following errors:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.shailendra.myapplication/com.example.shailendra.myapplication.MainActivity}: android.view.InflateException: Binary XML file line #8: Error inflating class com.example.shailendra.myapplication.DrawView

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"

Put draw View here
</ScrollView>
You can add your drawView with yourDrawer.addView(yourDrawView)
