I am getting org.json.JSONException: Value
at org.json.JSON.typeMismatch(JSON.java:111)
I hope you understand problem, I am still in learning stage so please give brief answer so that i can understand.

You are getting JSONArray from Response and trying to hold on JSONObject which causes org.json.JSONException: Value at org.json.JSON.typeMismatch(JSON.java:111) error
Try this
try {
JSONArray jsonArrayLST = new JSONArray(s);
for (int i = 0; i < jsonArrayLST.length(); i++) {
JSONObject contactObject= jsonArrayLST.getJSONObject(i);
String titleValue = contactObject.getString("title");
Integer pledgedValue = contactObject.getInt("amt.pledged");
Integer backersValue = contactObject.getInt("num.backers");
Project project = new Project();
project.setPleadges(pledgedValue);
project.setBackers(backersValue);
project.settitle(titleValue);
projects.add(project);
Log.v("Object details : " , " : " + pledgedValue + " : " + backersValue);
}
} catch (JSONException e) {
e.printStackTrace();
}
Also, you need to change in your adapter while setting item to textview, because your are setting int value which causes you android.content.res.Resources$NotFoundException: String resource ID error
pleadge.setText(String.valueOf(mList.get(position).getPleadges()));
backers.setText(String.valueOf(mList.get(position).getBackers()));

Filter functionality in custom ListView not working in android

I am newbie to android and working on a custom listView with custom adapter,I am having a listview and edittext,I want to add a searching feature using this,When user input some characters the listview should be filtered depending on the input,I have tried as below, Could someone help me to resolve this,

Since it seems you are just filtering on the getRoute_name() it may be easier to extend ArrayAdapter<Bus> which will do the filtering for you and then override the toString() for your Bus object to return the route name.
I don't think it's your filtering problem, but the getItem() should return a Bus object from your array list and not an Integer.
As #Daniel Wilson pointed out, your code is a bit difficut to read because of your variables that start with capial letters, it makes it look like a static method call.

android json parsing and image loading

I want to parse data and images via url of json.
I have used following code to do same. But i am not getting why the images disappear when i scroll down.
Can Anyone please tell me how can i stop to disappear images when i scroll down ?

populate different data in listview according to spinner selection in android

I have one spinner and I want to to populate the custom listview with the the data according to spinner selection. Data is coming from mysql database. Currently I am able to get the data from different spinner selection but the problem is when I try to add the data in listview it doesn't remove previous data from listview.
I tried listAdapter.notifyDataSetChanged() but this didn,t worked for me. Even I created 2 adapters for different spinner selections and tried to add them to list according to spinner selection but this gives me blank list.
I saw multiple solutions for my problem but nothing worked for me.
So please give me some suitable idea for adding different data to listview according to spinner selection.
Thanks in advance
this is my adapter class

So supposing you store your data in an ArrayList:
private ArrayList<VideoPreview> dataList = new ArrayList<>();
You can populate it in the spinner onItemSelectedListener:
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if (position != currentPosition) {
dataList.clear();
dataList = myData[position];
dataListView.getAdapter().notifyOnDataSetChanged();
}
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
Without knowing anything else of your problem and code, I cannot give you a more specific solution.
Your declaration of the adapter should look similar to this:
final DataAdapter adapter = new DataAdapter(getContext(), dataList);
dataListView.setAdapter(adapter);

If the data object you are passing is ArrayList<MyObject>
just make your custom adapter extend ArrayAdapter<MyObject> instead of BaseAdapter. Implement the required methods (leave default) and you should be fine.

Filter listview with custom adapter not filtering

this.records = objects;
} public int getCount() {
return records.size();
}

}
