search filter for Listview [duplicate]

I'm a beginner, I'm creating a job search app which shows job infomation as listview where the data is from WAMP server database. I encounter a problem : Cannot resolve method 'getStringArrayList' , when I'm making a search filter for this Listview. Please see line 11 of SearchFilter.java. Could anyone help? thank you very much!

getStringArrayList is a method on Bundle (such as savedInstanceState). There's no such method in Activity. Hope that helps.
Currently your infoList is an ArrayList>, something that is harder to pass directly to an activity. So find a way to represent it as an ArrayList, or find a more suitable datatype supported by Intent's putExtra-methods. Here below is a suggested solution using an ArrayList.
Passing the data into the activity with the Intent allows you to get it back in your SearchFilter. In the calling activity put something like this:
Intent i = new Intent(this, SearchFilter.class);
i.putStringArrayListExtra("com.yourpackagename.here.keynamehere", aStringArrayList);
In SearchFilter.java, put something like this:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
filterText = (EditText) findViewById(R.id.search_box);
filterText.addTextChangedListener(filterTextWatcher);
Intent startingIntent = getIntent();
ArrayList<String> arrayList = new ArrayList<String>();
if (startingIntent != null) {
arrayList = startingIntent.getStringArrayList("com.yourpackagename.here.keynamehere");
}
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
arrayList));
}

How to display the data from mySQL in listview in android?

I can insert data into database but now face the problem that cannot retrieve data from the database and display in listview in android. Here is my coding part for retrieve data. Hope someone can help to solve this, thank you.
package com.example.iuum;

Add ListView in activity_forum1a.xml
<ListView
android:id="#+id/list_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"></ListView>
Take ListView reference
private ListView mList;
Initialize it in onCreate
mList = (ListView) findViewById(R.id.list_view);
Take ListAdapter class Refernce
private ListAdapter listAdapter;
Add setListAdapter method
public void setListAdapter(ListAdapter listAdapter) {
this.listAdapter = listAdapter;
mList.setAdapter(listAdapter);
}
Change updateList method to
/**
* Inserts the parsed data into the listview.
*/
private void updateList() {
ListAdapter adapter = new SimpleAdapter(this, mCommentList,
R.layout.test, new String[] { TAG_TITLE, TAG_MESSAGE,
TAG_USERNAME }, new int[] { R.id.title, R.id.message,
R.id.username });
setListAdapter(adapter);
}
and perform item click operation outside from the method, by implementing onItemClickListener

how to display details of single item of list in another activity from url (json data)?

I have written a program to display the list of json data from a url which has an image and 5 textviews which is displaying perfectly.
Url : https://itunes.apple.com/search?term=jack+johnson&limit=50.
When i click on an item from the list i want to display the details of that item in another activity based on the track-id
Url : https://itunes.apple.com/lookup?id=659234741
So when i click on the item the details are getting displayed in the textview , but by default it is displaying the details of id = 659234741 for some items or in short the details does not match.
Need some help to figure out the problem

Thank you

The problem is that you are initializing the resultp each element in your getView method, so therefore the last id/element of the listview adapter's data will be considered as the resultp.
Im sure that the id 659234741 is the last element, which will always be the id for each onclick that would happen.
A solution for this is to create a final resultp within your getView method instead of having just one global resultp.
final HashMap<String, String> resultp = data.get(position);

Try to override onListItemClick in fragment :
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
Intent intent = new Intent(getActivity(), ProfilePage.class);
intent.putExtra("match_detail_id", aList.get(position).get(TAG_MATCH_ID));
startActivity(intent);
}
Instead of manual setOnItemClickListener to listview so no required this code :
listview=(ListView)rootView.findViewById(android.R.id.list);
listview.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
Intent intent=new Intent(getActivity().getApplicationContext(),ProfileEdit.class);
intent.putExtra("position", arg2);
startActivity(intent);
}
});
Note : when you use ListFragment no need to find Listview and set item click as well as setAdapter manually,directly get all method ready like setAdapter() and onListItemClick.

Intent intent = new Intent(getBaseContext(), NewActivity.class);
intent.putExtra("KEY", Value);
startActivity(intent)

Try with below code:
listview.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Intent intent=new Intent(getActivity(),ProfileEdit.class);
intent.putExtra("match_detail_id", arg2);
startActivity(intent);
}
});
//get this data as below in ProfileEdit class
String matchId=this.getIntent().getStringExtra(""match_detail_id"");
if(matchId.trim().length()>0){
USER_URL="http://gujjumatch.com/webservice/matchingdetails?version=apps&match_detail_id="+user_match_id;
}else{
Toast.makeText(ProfileEdit.this,"match id blank",Toast.LENGTH_LONG).show();
}

Simple Android Image Parsing

I'm attempting to parse image URLs and show the images in a ListView, but I continue to receive the ProtocalNotFound Exception/JSON Exception No value for null. I am pretty sure I'm close to translating the image URLs into bitmaps, but I'm off by something small. Any ideas for the right approach would be helpful. My class is below including the URL for the feed. Right now, I'm trying to convert the image URL in the loadImageFromWebOperations method. Please let me know if you need more information.
Android Class:

The problem is here
String profile_picture = c.getString(loadImageFromWebOperations(TAG_PROFILE_PICTURE.replaceAll(" ", "%20"),sdCard.getAbsolutePath() + "/dir1/dir2"));
First get they value for key and then load the url.
