I first display map with markers on it (defaulting to markers associated with the current date). User can then use datepicker to enter another date, and then they submit it like a form. Then new markers are displayed based on the date selected. The process of querying the dates I handle on the web server, not on the android. I just send the data back to the android so that the phone can then show markers. The part I am stuck is not the querying part. It's the part of how do I show a datepicker with the map. So that the user can select a date within the context of the map. This is what I have so far:
show_history.xml <?xml version="1.0" encoding="utf-8"?> <fragment xmlns:android="http://schemas.android.com/apk/res/android"; android:id="@+id/history_map" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.MapFragment"/> date_picker.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <Button android:id="@+id/myDatePickerButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Choose Date"/> <TextView android:id="@+id/showMyDate" android:layout_width="fill_parent" android:layout_height="wrap_content"/> </LinearLayout> showhistoryactivity.java public class ShowHistoryActivity extends Activity { MapView mapView; String authkey, unit_id; SharedPreferences preferences; private GoogleMap mMap; final Handler myHandler = new Handler(); protected List<Map<String, String>> historyData; private int mYear; private int mMonth; private int mDay; private Button mPickDate; private TextView mDateDisplay; static final int DATE_DIALOG_ID = 0; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.show_history); Intent intent=getIntent(); unit=intent.getStringExtra("unit"); preferences=PreferenceManager.getDefaultSharedPreferences(this); authkey=preferences.getString(AndroidRemoteContants.auth_token, "NULL"); mDateDisplay = (TextView) findViewById(R.id.showMyDate); mPickDate = (Button) findViewById(R.id.myDatePickerButton); System.out.println("value stored: " + mDateDisplay); mPickDate.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { showDialog(DATE_DIALOG_ID); } }); final Calendar c = Calendar.getInstance(); mYear = c.get(Calendar.YEAR); mMonth = c.get(Calendar.MONTH); mDay = c.get(Calendar.DAY_OF_MONTH); updateDisplay(); setUpMapIfNeeded(); } It already falls apart at this point because mDateDisplay is null. Essentially, I am not sure how to display a datepicker in the same screen as the map and have the two of them interact.
