Android藍牙搜索服務中的可用設備

Question

我試圖在后台服務中發現可用的藍牙設備。 我被困在“ startActivityForResult”部分，因為服務不是活動。 請幫忙...

private void CheckBTState() {
    // TODO Auto-generated method stub
      // Check for Bluetooth support and then check to make sure it is turned on
    // If it isn't request to turn it on
    // List paired devices
    // Emulator doesn't support Bluetooth and will return null
    Log.d("check","4");
      if (btAdapter.isEnabled()) {
//        out.append("\nBluetooth is enabled...");

        // Starting the device discovery
        btAdapter.startDiscovery();
        Log.d("check","5");
      } else {

        Intent enableBtIntent = new Intent(btAdapter.ACTION_REQUEST_ENABLE);
        Log.d("check","6");

  STUCK OVER HERE.... DON'T NO HOW TO CALL startActivityForResult IN SERVICE

 // ((Activity) context).startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
      //  activity.startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);


      }


}

服務啟動之前，您必須先激活藍牙。

只需將以下代碼添加到您的活動中：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (requestCode == <needed value>) {


    }
    super.onActivityResult(requestCode, resultCode, data);
}
