I am inflating the menu from JSON which contain its name and id. I had written Fragment5 which is used to be calling an URL for JSON. In that url I want to call the id of the menu.
This is my code. The code is running fine if I am commenting the two line

Perhaps you get exception during JSON parsing. You may surround Integer.parseInt(scat); with try- catch catching ParsingException if Json has no such a field.
But more neat solution is to use GSON with Retrofit, so you can automatically parse you response to java objects, created by jsonschema2pojo.com
I have two activities...In first activity its a list view where i get the data from the Json file....now when user click on an item of the list view a new activity should open...so i pass the id from activity 1 to activity 2 using an intent. Instead of sending all the details using intent is there any other way that i can only pass the id to activity 2 and then query json file to get details (json object) and then update the UI.
Here is my code.

You will need a proper endpoint to get the toy details. Normally passing the id as a REST path (android_login_api/toys/) or in the query string (android_login_api/toys?id=), there are multiple options.
If you have only the endpoint with the list of toys, instead of passing only the id to the Activity2, you can also use the intent to send the json section of the toy which user have been selected, as a string. So, Activity2 will receive the json data in the intent data.
Anyway, I extremely recommend you to use a serialisation library, such as GSON or Jackson, to convert JSON into Java classes. It is easy to create a model from JSON objects and configure Volley to return the required model Java class (or list) when you send a Volley request.
I have this code that receives the RSS feed and displays it into a Row, however, it does not carry over the image once the row has been clicked. How do I achieve this image transfer from the list view to the detailed view.
This is the RSS Reader View

You can send Image via Intent as ByteArray or try loading from URL. Loading from URL is preferred as it will not bring OutOfMemoryException or any other issues while passing large bitmap images via Intent. If image is small, you may pass them via Intent.
The code below shows both the methods. Implement which suits your need or works in your URL case.
Sender Activity
//Download image from thumbUrl to bitmap
URL newurl = new URL(myRssFeed.getItem(position).getThumburl());
Bitmap bitmap = BitmapFactory.decodeStream(newurl.openConnection() .getInputStream());
Intent intent = new Intent(mAct, RssDetailActivity.class);
Bundle bundle = new Bundle();
bundle.putString("keyTitle", myRssFeed.getItem(position).getTitle());
bundle.putString("keyDescription", myRssFeed.getItem(position).getDescription());
bundle.putString("keyLink", myRssFeed.getItem(position).getLink());
bundle.putString("keyPubdate",myRssFeed.getItem(position).getPubdate());
//pass image url
bundle.putString("keyThumburl", myRssFeed.getItem(position).getThumburl());
//sent image bitmap byte array
ByteArrayOutputStream bs = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 50, bs);
bundle.putByteArray("byteArray", bs.toByteArray());
intent.putExtras(bundle);
startActivity(intent);
Receiver Activity
Bundle bundle = this.getIntent().getExtras();
//load from bitmap bytearray
Bitmap bitmap = BitmapFactory.decodeByteArray(bundle.getByteArray("byteArray"),0,bundle.getByteArray("byteArray").length);
imageView.setImageBitmap(bitmap);
//or load from image url
new LoadImage().execute(bundle.getString("keyThumbUrl"));
Create an AsyncTask to load image to ImageView from URL sent via Intent
private class LoadImage extends AsyncTask<String, String, Bitmap> {

try {
Bitmap bitmap = BitmapFactory.decodeStream((InputStream)new URL(args[0]).getContent());

SearchFragment extends ListFragment. In a ListFragment, getListView() cannot be called in onCreateView(), because onCreateView() is creating the fragment's content view and has not yet completed. The call to getListView() in SearchFragment is the cause of the exception.
Move the the call to getListView() and related to code to one of the fragment lifecycle methods that is called after onCreateView(), such as onViewCreated() or onActivityCreate(). For example:
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
ListView lv = getListView();
// Listview on item click listener
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
String name = ((TextView) view.findViewById(R.id.name))
.getText().toString();
String code = ((TextView) view.findViewById(R.id.code))
.getText().toString();
// Starting single contact activity
Intent in = new Intent(getActivity().getApplicationContext(),
Details.class);
in.putExtra(TAG_NAME, name);
in.putExtra(TAG_CODE, code);
startActivity(in);
}
});

I'm new to android programming and I'm practicing in making a Facebook app. I got this ListView and which i will be using to display some information i got from facebook. But the problem is when the Listview starts to load the datas its stucked in the loading part and its taking forever but theres no error in the codes. here are the codes:

And heres the xml:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment
android:id="#+id/titles"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.example.forwardjunction.FragmentLayout$TitlesFragment" />
</FrameLayout>
I hope you can help me. cheers
*edit> I think the problem is that the listview is empty, i dont really know where the problem is
because the UI thread is Blocked
Rather than using your thread class use Asynctask
class xyz extends Asynctask
{
}
then add to overrididen methods
do in background
on post execute
