After i made some changes in an AsynTask i get this error when running the app:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.android.popularmovies/com.example.android.popularmovies.MainActivity}: android.view.InflateException: Binary XML file line #1: Error inflating class fragment
This is the activity_main.xml file.
<fragment xmlns:android="http://schemas.android.com/apk/res/android"

android:name="com.example.android.popularmovies.MainActivityFragment"
tools:layout="#layout/fragment_main"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
And this is the MainActivity.java file:
package com.example.android.popularmovies;

getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {

return true;
}
return super.onOptionsItemSelected(item);
}
}
Thanks for any help you can provide! ;)
I am not sure try the following:
Add
tools:context= ".MainActivity"
or Can you put <fragment> inside a <FrameLayout>.
Clean the code once.

Can't really tell what you mean by not working without any log or explanation.
Here are some possible reason:
cannot reach server at url http://localhost:8081/geoserver/NFR-SR/wms
layer name NFR-SR:Ridgeline_SR not found
map service doesn't support application/openlayers
It could even be it is working but you are viewing the map extent which does not contain any data.
I have a navigation drawer and against each item within the drawer there is one fragment page. I want to implement tabbed swipe within one fragment. How do I do that.
Here's my code after clicking to one navigation drawer fragment page. I want to implement the tabbed view within this page. What's the way?
//Code
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v7.app.ActionBar;
import android.support.v7.widget.Toolbar;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
/**
* A simple {#link Fragment} subclass.
*/
public class SalesFragment extends Fragment {
private Toolbar mToolbar;
public SalesFragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
setHasOptionsMenu(true);
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_sales, container, false);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.toolbar_menu, menu);
super.onCreateOptionsMenu(menu, inflater);
}
#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.add_user) {
return true;
}
if (id == R.id.barcode_scanner) {
return true;
}
if (id == R.id.search_overflow) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
//and here is the layout xml page
<FrameLayout 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"
tools:context="com.soumya.possystem.SalesFragment">
<!-- TODO: Update blank fragment layout -->
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Sales page"
android:textSize="40dp"/>
</FrameLayout>
You can created tabbed fragment page viewer by using Android Studio Activity Gallery. Just follow the below steps and create in half minute.
-> File -> New -> Activity -> Choose the type Tabbed Activity
-> Choose Navigation Style Action Bar Tabs (With ViewPager)
Enjoy Coding !
So I'm starting to work on my first Android App and I've already hit a wall. I want to start off with a "Create" button at the action menu at the top that has the ability to create new contacts. But then I hit some sort of error I can't understand and it's been hindering my process.
The error started when I added the "onClick" line tot he action item and since then, stopped running on my emulator.
Thank you.

public void create(View v){
TextView tv = (TextView) findViewById(R.id.test);
tv.setText("Working!");
}
}
This might help: the menu_main.xml.
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" tools:context=".MainActivity">
<item android:id="#+id/action_settings" android:title="#string/action_settings"
android:orderInCategory="100" app:showAsAction="never" />
<item
android:id="#+id/add"
android:title="Add New Contact"
app:showAsAction ="always"
android:icon="#drawable/ic_add_white_48dp"
android:onClick="create"/>
</menu>
And finally, the error:

You create method needs to take a MenuItem as the argument, not a View.
public void create(MenuItem item){
TextView tv = (TextView) findViewById(R.id.test);
tv.setText("Working!");
}
Alternatively, remove the android:onClick attribute of your menu item and handle the click in onOptionsItemSelected() by checking the id of the item:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.add:
// your code here
return true;
case R.id.action_settings:
// copied from auto-generated stub
return true;
}
return super.onOptionsItemSelected(item);
}
Either will work, my preference is the second approach.
You'd be better off doing it programmatically. Get rid of the 'android:OnClick' line in the XML, then after you set the text of 'tv' put in this:
tv.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Process click here
});
This should do the trick!

I apologize that I am posting this as an answer instead of a comment, but commenting requires 50 reputation and I don't have that yet. Can you post your java code too? The problem is likely in there, it may be the method by which you are loading the view.
I am creating an android application that consists of navigation drawer in android studio.

startActivity(sub);

Just go to your Fragment_navigation class and
replace
import android.app.Fragment;
with
import android.support.v4.app.Fragment;
