break;
case 1:
Intent e = new Intent(getActivity(), AActivity.class);
e.putExtra("categoryId", 2);

startActivity(e);
break;
case 2:
Intent f = new Intent(getActivity(), AActivity.class);
f.putExtra("categoryId", 3);

break;
<?php
if($_SERVER['REQUEST_METHOD']=='POST'){
include_once($_SERVER['DOCUMENT_ROOT']."/config/config.php");
$id= $_POST['id'];
// Create connection
$conn = new mysqli($host, $user, $pass, $database);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM comments where comment_id = '$id'" ;
$result = $conn->query($sql);
if ($result->num_rows >0) {
while($row[] = $result->fetch_assoc()) {
$tem = $row;
$json = json_encode($tem);
}
} else {
echo "No Results Found.";
}
echo $json;
$conn->close();
}
?>

HTML is not JSON, and it can not be parsed into JSONObjects. The top answer for org.json.JSONException: Value <!DOCTYPE of type java.lang.String cannot be converted to JSONObject is pretty good at explaining this further.

and the BaseAdapter:

//setOnClickListener on PreviewImage for PopOutGallery
beitragImageView.setOnClickListener(new OnClickListener() {

#Override
public Object getItem(int position) {
return beitraege.get(position);
}
#Override
public long getItemId(int position) {

return 0;
}
}
In my opinion the Bug have to be in the BaseAdapter, but I don't know where it could be.
Sincerly and thankful,
Simon
To fill listView in doInBackground you need to use Handler, or runOnUiThread, because this is not UI thread.
homeActivity.runOnUiThread(new Runnable()
{
public void run()
{
homeActivity.addToListView(tempBeitrag);
}});
adapter = new listViewHomeActivitiyAdapter(this, beitraege);
beitraege is not populated with any data.
Edit:
Instead of calling this from doInbackground. Use a Interface as a call back to the activity and then populate listview.
public void addToListView(Beitrag toAddBeitrag){
beitraege.add(toAddBeitrag);
adapter.notifyDataSetChanged();
}
How do I return a boolean from AsyncTask?
Instead of boolen value its arraylist in your case.
Then use the below and set the adapter your listview
adapter = new listViewHomeActivitiyAdapter(this, beitraege);
