I recently just overhauled my application to use ListView instead of using the classic TextView.setText and looping the inflation of a layout. I was able to acheive this very well but now I’m having a problem having it fill the screen. Heres the section of my code that does the work.
//Place JSON data into array one item at a time
JSONArray jArray = new JSONArray(result);
//Loop through each record in the database
//Get ListView
ListView lv= (ListView)findViewById(R.id.listview);
// create the grid item mapping
String[] from = new String[] {"lblQuote", "lblBuzzed", "lblShared", "lblSaid", "lblLikes", "lblHates", "lblLocation", "lblDate"};
int[] to = new int[] { R.id.lblQuote, R.id.lblBuzzed, R.id.lblShared, R.id.lblSaid, R.id.lblLikes, R.id.lblHates, R.id.lblLocation, R.id.lblDate };
for(int i=0;i<jArray.length();i++){
Log.i("uDrew Debug", "Made it into JSONArray Loop");
//Get this record
JSONObject json_data = jArray.getJSONObject(i);
//Put each result into variables for later handling
strFName = json_data.getString("FName");
strLInitial = json_data.getString("LInitial");
strCity = json_data.getString("City");
strState = json_data.getString("State");
strDate = json_data.getString("Date");
strQuote = json_data.getString("Quote");
intLikes = Integer.parseInt(json_data.getString("Likes"));
intHates = Integer.parseInt(json_data.getString("Hates"));
strFNameSaid = json_data.getString("FNameSaid");
strLInitialSaid = json_data.getString("LInitialSaid");
intBuzz = Integer.parseInt(json_data.getString("Buzz"));
Log.i("uDrew Debug", "Made it past JSON Parsing");
switch(intBuzz){
case 1:
strBuzzed = ("One Beer\nSyndrome");
break;
case 2:
strBuzzed = ("Buzzed");
break;
case 3:
strBuzzed = ("Drunk");
break;
case 4:
strBuzzed = ("Trashed");
break;
case 5:
strBuzzed = "Retarded";
break;
}
HashMap<String, String> map = new HashMap<String, String>();
map.put("lblQuote", strQuote);
map.put("lblBuzzed", strBuzzed);
map.put("lblShared", strFName + " " + strLInitial);
map.put("lblSaid",strFNameSaid + " " + strLInitialSaid);
map.put("lblDate", strDate);
map.put("lblLocation", strCity + ", " + strState);
map.put("lblLikes", intLikes.toString());
map.put("lblHates", intHates.toString());
fillMaps.add(map);
}//End For loop
// fill in the grid_item layout
SimpleAdapter adapter = new SimpleAdapter(this, fillMaps, R.layout.myviews, from, to);
lv.setAdapter(adapter);

Heres what the App looks like:
There are also no scrollbars and if I change the main.xml ScrolView layout_height=”fill_parent” it extends to the end of the screen but the scrollable option isn’t there.
The following code fixed my problem:
