Changing the default listViews item clicked to StringBuffer instead (displays popup by default)

I have a ListView that displays a list of items and I want to display further more details when any item is clicked using StringBuffer. But I'm having an issue because android default setOnItemClickListener bypasses the StringBuffer view that I'm defining inside the click event, and just displays the the item view in a popup.
Here is my code and I will include some screen shots in order to clarify my point a bit more

Here is what I get
here is the logcat error after making the modifications

You have defined onClickListener on your list-items (rowView.setOnClickListener) - this is what gets called instead of the listView's setOnItemClickListener. You need to remove (comment out) this in the CustomListAdapter class:
rowView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(context, "You Clicked "+result[position], Toast.LENGTH_LONG).show();
}
});
You need to also call listView.setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS); so that only the listView's item click listener can be invoked even if the row item of list are set as focusable or clickable.
Then the dialog should show as you'd expect. Please try this and let us know if it works or what errors you get.

How to retrieve editText saved value after reopening the application?

I have create a listview activity which opens dialog boxes on item click. In the dialog box, the users can enter different value which are saved in a textView, in the same list view item. That's working perfect, the problem is that if I close the application, when I open it again, the values saved, aren't there anymore. How to keep the value after closing the application? Thanks !!!

MODE_PRIVATE).edit();
editor.putString("TVEntries", toSave);
editor.commit();
}
#Override
protected void onResume() {
// TODO Auto-generated method stub
SharedPreferences prefs = getSharedPreferences("LV Data", MODE_PRIVATE);
String encoded = prefs.getString("TVEntries", "");
String[] entries;
if (encoded.equals(""))
entries = null;
else
entries = EncodeDecode.decode(encoded);
NoteAdapter adapter = (NoteAdapter) lv.getAdapter();
adapter.savedEntries = entries;
lv.setAdapter(adapter);
super.onResume();
}
}

Here's a proposed solution involving SharedPreferences:
First, add a String[] instance variable to your Adapter class. This will contain what you want to save(the fields inside your TextViews. Initialize this your constructor.
public NoteAdapter(Note note, String[] saved, String[] prgmNameList, int[] prgmImages) {
result=prgmNameList;
context=note;
imageId=prgmImages;
inflater = ( LayoutInflater )context.
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
/**********INSERTED CODE********/
if(saved == null) {
savedEntries = new String[result.length];`
Arrays.fill(savedEntires, "");
}
else
savedEntries = saved;
/****************************/
}
Also modify your overriden getItem() method to return the appropriate element in savedEntires:
#Override
public Object getItem(int position) {
return savedEntries[position];
}
Whenever you update a TextView, update the list accordingly:
#Override
public void onClick(View v) {
String data = txtMode.getText().toString();
holder.text.setText(data);
/***INSERTED CODE****/
savedEntries[position] = data;
/*******************/
dialog.dismiss();
Log.d("data", data);
}
We will save this array in SharedPreferences using a String-String pair. Since Strings can potentially contain any character, it is difficult/inefficient to find a single delimiter. I implemented a class called EncodeDecode that can encode a String array into a single formatted String, and decode it back to a String array here: https://gist.github.com/liangricha/10759438. I'll be using this class to convert/unconvert savedEntries.
Whenever you want to save savedEntries(in onStop()), simply execute this code:
ListView lv = //... get reference
NoteAdapter adapter = (NoteAdapter)lv.getAdapter();
//Variable is public for clarity.
String toSave = EncodeDecode.encode(adapter.savedEntries);
SharedPreferences.Editor editor = getSharedPreferences("LV Data", MODE_PRIVATE).editor();
editor.putString("TVEntries", toSave);
editor.commit();
When you want to retrieve the String array of your TextView entries(in onResume()), execute:
SharedPreferences prefs = getSharedPreferences("LV Data", MODE_PRIVATE);
String encoded = prefs.getString("TVEntries", "");
String[] entries
if(encoded.equals(""))
entries = null;
else
entries = EncodeDeocde.decode(encoded);
NoteAdapter adapter = (NoteAdapter)lv.getAdapter();
adapter.savedEntries = entries;
lv.setAdapter(adapter);
Then, in your getView() method of 'NoteAdapter', set the field of the TextView to the appropriate entry in savedEntries:
holder.text.setText(savedEntries[position]);

trying to add a Custom ListView With an Adapter to a Fragment?

I'm trying to add a Custom ListView With an Adapter to a Fragment.
I don't Know where is the problem exactly, I think I got everything in place yet I cant get rid of the Unfortunately Stopped message.

You never initialize the List<Question> questions in your fragment.

You never initialize your question collection. That's why it stops when you try to add questions in onCreateView. Either initialize List questions initially or some time before you try to add things to it.

Dynamic ListView - Refresh on Button Click

Android 2.3.3
I have seen few questions at stackoverflow, regarding refreshing the listview. But none of them worked for me.
I have a dynamic listview and I have a button inside it. The data is being populated from database and each listview row is a custom layout. On press of the (Clear) button, the database is cleared(which works fine) and the listview should get refreshed(the part to be figured out).
Below is the code...
import java.util.ArrayList;
import android.app.Activity;
import android.app.ListActivity;

public class History extends ListActivity {
ListView lvHistory;
ArrayAdapter<String> adHistory;
ArrayList<String> alHistoryCopy = new ArrayList<String>();
String[] emptyList = { "Your Calculations History is Empty. Please Perform Some Calculations and visit again." };
Database db;
Cursor c;
String expression = "";
String result = "";
boolean isEmpty = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
// setContentView(R.layout.history);
lvHistory = getListView();
final MyCustomAdapter myad = new MyCustomAdapter();
db = new Database(this);
c = db.retrieve_history();
if (!((c.moveToFirst()) || c.equals(null) || c.getCount() == 0)) {
} else if (c.getCount() > 0) {
c.moveToFirst();
}
LayoutInflater header = getLayoutInflater();
View header_View = header.inflate(R.layout.history_header, null);
lvHistory.addHeaderView(header_View);
View second_Header_View = header.inflate(
R.layout.history_second_header, null);
lvHistory.addHeaderView(second_Header_View);
Button btnClearHistory = (Button) second_Header_View
.findViewById(R.id.btnClearHistory);
btnClearHistory.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub

}
});

} else {

}
viewHolder.txtcnt.setText(String.valueOf(position + 1));
System.out.println("Position"
+ viewHolder.txtcnt.getText().toString());
c.moveToPosition(position);
expression = c.getString(c.getColumnIndex("expression"));
result = c.getString(c.getColumnIndex("result"));
viewHolder.txtexp.setText(expression);

if (db != null) {
db.close();
}
if (c != null) {
c.close();
}
}
}
EDIT ::: With ScreenShots :::

Try to extend your MyCustomAdapter from BaseAdapter and use notifyDataSetChanged to refresh ListView.
The better way to display database content is CursorAdapter (or CursorLoader) - such adapters listen for update notifications and reloads the content automatically.

try this, You need to refresh you ListView after delete one item using myad.notifyDataSetChanged();
btnClearHistory.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
YourActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
myad.notifyDataSetChanged();
}
});
}
});

Try add c = db.retrieve_history(); after db.clear_history();.
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
db.clear_history();
c = db.retrieve_history();
myad.notifyDataSetChanged();
lvHistory.invalidateViews();
lvHistory.refreshDrawableState();
}
Hope this helped you.

Just restart your activity..
ActivityName.this.finish();
Intent intent=new Intent(this, ActivityName.class);
startActivity(intent);

#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_loja, container, false);

Toast.makeText(getActivity(), "Position :"+itemPosition+" ListItem : " +itemValue , Toast.LENGTH_LONG) .show();
updateData();

listatividade.setAdapter(adapteratividade);

How do i get image from imageUrl in imageView

How can i get image from image url in image view.
My imageUrl is coming from databaseadapter.
In Fields class LocationImage dataype is string but in setBackgroundResource method it is asking for int value as parameter. LocationImage url is getting from database, so that i've taken that as string variable.
