I am trying to create an app that shows positions where i have been in googlemaps. Then I have some seekbars that changes what days and during which time I want to show where i have been for example. I got a code working when I have the googlemaps fragment and the seekbar (using crystal seekbar) in that same acitivy sharing the space on the screen. But now I want to increase the size of the googlemap and instead have the seekbars in a other layout showed by a dialog when hitting a button called settings. I cannot get that to work because it complains about Views and I do not want to remove the view because then all my parameters and stuff changes back to sarting values and stops working. Below I show my code for the class and the error message.
Here declaration of the seekbar in the mainactivity: @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main);
LayoutInflater inflater = (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
layout_settings = (LinearLayout)inflater.inflate(R.layout.dialog_settings, null);
//Initialize
InitializeUI();
//Makes buttons work
onClickListener();
//UpdateGuiStart
updateStartGUI();
//Seekbars
SeekBarCheckBoxModeController();
}
And here is where i initilize all my seekbars:
public void InitializeUI() {
GPSButton = (Button) findViewById(R.id.GPSButton);
mapsButton = (Button) findViewById(R.id.mapsButton);
TextSpeed = (TextView) findViewById(R.id.TextSpeed);
check_view = (TextView) findViewById(R.id.textView_check);
deleteData = (Button) findViewById(R.id.button_delete);
settings = (Button) findViewById(R.id.button_settings);
TextSpeed.setText("Speed : " + speed);
mModeSpinner = (Spinner) layout_settings.findViewById(R.id.spinner);
mSeekBarTime = (CrystalSeekbar) layout_settings.findViewById(R.id.rangeSeekbarTime);
mSeekBarDate = (CrystalRangeSeekbar) layout_settings.findViewById(R.id.rangeSeekbarDate);
mSeekBarTimeLength = (CrystalSeekbar) layout_settings.findViewById(R.id.rangeSeekbarTimeLength);
mSeekBarTransparency = (CrystalSeekbar) layout_settings.findViewById(R.id.rangeSeekbarTransparency);
tvMinTime = (TextView) layout_settings.findViewById(R.id.textViewMinTime);
tvMaxTime = (TextView) layout_settings.findViewById(R.id.textViewMaxTime);
tvMinDate = (TextView) layout_settings.findViewById(R.id.textViewMinDate);
tvMaxDate = (TextView) layout_settings.findViewById(R.id.textViewMaxDate);
tvMaxDates = (TextView) layout_settings.findViewById(R.id.textViewMaxDates);
tvTransparency = (TextView) layout_settings.findViewById(R.id.textViewTransparency);
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.fragment_map);
mapFragment.getMapAsync(this);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
//Initialize database helper
mDbHelper = new LocationDbHelper(this);
}
and here is my alertdialog for showing the seekbars where I want to do my changes that should be done on the map and when i click there again i want my seekbars to stay the same way i left the last time I changed something...
settings.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
minday = current_minday;
maxday = current_maxday;
mintime = current_time;
maxtime = maxTime;
trans = current_trans;
mode = mModeSpinner.getSelectedItemPosition();
final AlertDialog.Builder settings_alert = new AlertDialog.Builder(MainActivity.this);
settings_alert.setView(layout_settings);
settings_alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
show();
Toast.makeText(MainActivity.this, "Settings changed", Toast.LENGTH_LONG).show();
dialogInterface.dismiss();
}
}).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
mSeekBarDate.setMaxStartValue(maxday);
mSeekBarDate.setMinStartValue(minday);
mSeekBarTime.setMinStartValue(mintime);
mSeekBarTimeLength.setMinStartValue(maxtime);
mModeSpinner.setSelection(mode);
dialogInterface.dismiss();
}
}).show();
}
});

The above code must be local to the onClick event.
It should be like this:
