Custom InfoWindow for Google Maps Android API v2


To create Custom InfoWindow for Google Maps Android API v2:

- Make your Activity implements GoogleMap.InfoWindowAdapter.

- Override getInfoWindow(Marker marker) and getInfoContents(Marker marker).

The API will first call getInfoWindow(Marker) and if null is returned, it will then call getInfoContents(Marker). If this also returns null, then the default info window will be used.

The first of these (getInfoWindow()) allows you to provide a view that will be used for the entire info window. The second of these (getInfoContents()) allows you to just customize the contents of the window but still keep the default info window frame and background.

- setInfoWindowAdapter(this).


Modify MapsActivity.java from last example "Make GoogleMap's marker draggabe and detect moving marker".

Connect Windows 10 to HC-06 Bluetooth

This post show how to connect Windows 10 to HC-06 Bluetooth Module.


Actually it's a loopback connection:
PuTTY Serial connect to Bluetooth Outgoing port -> (Bluetooth) -> HC-06 -> FT232RL -> (USB) -> Arduino IDE Serial Monitot.


This video show how to pair HC-06 on Windows 10, and try the loopback test.

Android Bluetooth connect PC (running Windows10) via HC-06 BT Module and FTDI US-to-Serial adapter




Last post show a "Android communicate with Arduino + HC-06 Bluetooth Module". Alternatively, the HC-06 can connect to PC via a FTDI USB-to-Serial adapter, such that Android can talk to PC by Bluetooth.

This video show how to:


Android side, refer to last post "Android communicate with Arduino + HC-06 Bluetooth Module", with source code and APK.

In my setup, both FT232RL (FTDI USB-to-Serial adapter) and HC-06 (Bluetooth Module) operate on 3.3V.
Connection:
HC-06 VCC - FT232RL VCC *make sure both devices work on the same voltage.
HC-06 GND - FT232RL GND
HC-06 TXD - FT232RL RXD
HC-06 RXD - FT232RL TXD

PC running Windows 10, connect to FT232RL by USB.

Serial Monitor of Arduino IDE is used as a terminal to talk with Android.


Android communicate with Arduino + HC-06 Bluetooth Module, part II

It's my old post "Android example to communicate with Bluetooth device, HC-06 Bluetooth Module", to make a Android phone communicate with Arduino + HC-06 Bluetooth Module. In the example, the first byte always lost.

After more test, I found that the first byte not lost. Because the byte stream sent from Arduino not in sync with Android side, and the bytes may be separated in different slot received in Android ThreadConnected, and the old slot covered by the new slot.

To show it, I modify it not to clear the TextView.

Make GoogleMap's marker draggabe and detect moving marker


To make GoogleMap's marker draggabe and detect moving marker:
- Modify MapsActivity to implement GoogleMap.OnMarkerDragListener
- Override onMarkerDragStart(Marker marker), onMarkerDrag(Marker marker) and onMarkerDragEnd(Marker marker), to handle the MarkerDrag events.
- Assign OnMarkerDragListener by calling mMap.setOnMarkerDragListener(this).
- Set markers draggable by calling markerOptions.draggable(true).


Modify MapsActivity.java from last post "Detect touch on GoogleMap, onMapClick() and onMapLongClick()".

Next: - Custom InfoWindow for Google Maps Android API v2
~ Step-by-step of Android Google Maps Activity using Google Maps Android API v2, on Android Studio

Detect touch on GoogleMap, onMapClick() and onMapLongClick()


To detect touch on GoogleMap, modify MapsActivity.java from last example "Google Maps Android API v2 - initialize map in xml".

Edit MapsActivity to implements GoogleMap.OnMapClickListener, GoogleMap.OnMapLongClickListener.

Implement your listeners, onMapClick() and onMapLongClick().

Assign the listeners to your GoogleMap by calling:
mMap.setOnMapClickListener(this);
mMap.setOnMapLongClickListener(this);
