1. 选中扫描到的 Thingy 52 蓝牙设备;
文件: ScannerFragment.java
public Dialog onCreateDialog(final Bundle savedInstanceState) {
......
builder.setTitle(R.string.scanner_title);
final AlertDialog dialog = builder.setView(dialogView).create();
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(final AdapterView<?> parent, final View view, final int position, final long id) {
stopScan();
dismiss();
final ScannerFragmentListener listener = (ScannerFragmentListener) getActivity();
final ExtendedBluetoothDevice device = (ExtendedBluetoothDevice) mAdapter.getItem(position);
listener.onDeviceSelected(device.device, device.name != null ? device.name : getString(R.string.not_available));
}
});
......
}2. 联结 Thingy 52 蓝牙设备
文件: InitialConfigurationActivity.java
public void onDeviceSelected(BluetoothDevice device, String name) {
if (mThingySdkManager != null) {
mThingySdkManager.connectToThingy(this, device, ThingyService.class);
}
mDevice = device;
animateStepOne();
showConnectionProgressDialog();
}文件: ThingySdkManager.java
注: 对于 Thingy 52 的蓝牙操作, 手机 App 是以后台服务形式实现;
启动服务

mServiceConnectionListener = (ServiceConnectionListener) context;
final Intent intent = new Intent(context, service);
context.startService(intent);
context.bindService(intent, mServiceConnection, 0);
}服务定义
