Android studio, loading 2 spinners with different data from different MYSQL databases

My app has an itinerary function, the part where you create a new itinerary involves selecting from 2 spinners which drop down to present different options. The data coming from MQsql database and the JSON response is correct for both sets. Currently i have been able to get either one set of the data to load in the correct spinner (being which either just transport info or attraction info but not both), or i have been able to get both sets of data to load but both are displayed in the same 2 spinners. I need them to be separated into there allocated spinners but need help doing this as i dont undertand what im doing wrong.

how to set background color of list view in android using java

i want to set the background color of listview using java...
Below is the code in which i want to set the background color of list view.
value in the name,address,varificationtype comes from server.
now i want to set the background color of listview to RED.
I already defined

How can I do this only using Java here?

Update your code in onPostExecute()
#Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
// Dismiss the progress dialog
if (pDialog.isShowing())
pDialog.dismiss();
final ListAdapter adapter = new SimpleAdapter(GetLead.this, contactList, R.layout.list_item, new String[]{TAG_ID, TAG_NAME, TAG_ADDRESS, TAG_VARTYPE, priority}, new int[]{R.id.custId,
R.id.name, R.id.address, R.id.verificationType});
if (priority.equals("high")) {
GetLead.this.runOnUiThread(new Runnable() {
#Override
public void run() {
setListAdapter(adapter);
getListView().setBackgroundColor(getResources().getColor(R.color.colorAccent));
}
});
}
}

You should do this in your adapter, override getView like this:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = inflater.inflate(R.layout.custom_event_row_view, parent, false);
convertView.setBackgroundColor(Color.RED);
Now you can set the color of each entry as you wish.

Actually you have to set the layout background color used in xml to set color accordingly.
if (priority.equals("high")) {
LinearLayout listLayout = listItem.findViewByid(R.id.list_layout);
listLayout.setBackground(R.color.Red)
setListAdapter(adapter);
}

Strange behavior of custom listview with sqlite

I am trying to create a shopping cart app and everything was going great but now i am stuck for last three day did search lot in stackoverflow but could not get a answer.I am populating listview from server and there is two buttons in each row plus(for adding quantity) and minus for (decrements it). This is the screen where i am adding quantity to cart.
I am trying to insert row to sqlite database upon clicking either of two buttons and i have achieved this and i am show these data in next activity inside a listview. Here my problem starts when i insert data it shows it properly but during updation it is showing strange behavior. If i click on first three rows the insertion and updation working fine but if i scroll down and click on any item then instead of updating each time its inserting.. I know this question is quite big and lengthy but i could not find a good way to summarize it sorry.. Please help me thanks ..
This is the screen which i am getting as output.

actually it wont filter because youve cleared the driverList and then in the else statement you loop to driverList which is already empty. the only thing you can do is create a backup list for the driversList and then use the backup list to get all data for filtering to the driverList.
Example Here:
// here is the backuplist
ArrayList<Drivers> backupList = new ArrayList<Drivers>();
// Filter Class
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
// actually its easy to just clear the backup list
// but due to reasons where users press backspace you have to load backup list only once
if(backupList.isEmpty()) {
backupList.addAll(driverList);
}
driverList.clear();
if (charText.length() == 0) {
driverList.addAll(backupList);
} else {
for (Drivers driver : backupList) {
if (driver.getName().toLowerCase(Locale.getDefault()).contains(charText)) {
driverList.add(driver);
}
}
}
notifyDataSetChanged();
}
Hope it helps :)

TimePicker Saves Zero Value in SQLite Database

I have a TimePicker which I'd like to use to determine a length of time a user can stay connected. Lets say the time now is 10:00 if the user selects 11:00 - I'd like the source code below to determine that there are 60 minutes between the current time - and the time selected and set that to a string/long (minutes) which I then have displayed as a textview.
I've coded everything as I thought it should be - however the textview never seems to update with minutes value. Everytime I attempt to view the data - I get a value of 0 not matter what the timepicker is set to.
Anyone have any suggestions? I'm stumped at the moment and I'm not sure what else to try.
ADDEDITDEVICE.JAVA (where the timepicker and minutes determination takes place)
public class AddEditDevice extends Activity {

You have that code to add a contact, BUT in your database conector you have:
public void insertContact(String name,
String cap,
String code,
String time,
long minutes,
String ssid,
String string){
I think that don't match, so this is why don't insert correctly.
BTW i can't comment at the moment because i need 50 reputation.

USE CREATE TABLE IF NOT EXISTS T/N then your problem wil be solved.
otherwise it will override the current table at the same time all the data will be lost.
