Android: Broadcastreceiver con Achartengine, no mostrar actualizaciones
Estoy tratando de mostrar la información obtenida del escaneo wifi con el receptor de transmisión, en un gráfico de barras usando achartengine. Bueno, quiero tener un gráfico en tiempo real, cada vez que recibo datos del método onReceive (), actualizo el gráfico. Para lograr eso, creo los objetos de gráfico en el método onReceive (). Pero acabo de obtener un gráfico con el primer resultado, no hay actualización, aunque puedo ver los cambios en el escaneo wifi. Me gustaría saber cuál es el problema.Este es el código que estoy usando:
public class WifiChartsRealTime extends Activity {
LinearLayout layout;
List<int[]> values = new ArrayList<int[]>();
//List<ScanResult> classObject = new ArrayList<ScanResult>();
int [ ] [ ] Center_Frequency_2 = { { 1,2,3,4,5,6,7,8,9,10,11,12,13,14 },
{ 2412, 2417, 2422, 2427, 2432,2437,2442,2447,2452 ,2457,2462,2467,2472,2484},
};
WifiManager wifi;
Button enab;
String resultsString ;
String[] myStringArray;
int aa = 10;
public class Receiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
int length ;
if(intent.getAction().equals(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION)){
List<ScanResult> results = wifi.getScanResults();
length=results.size();
Toast.makeText(getApplicationContext(),
"resultsString***************** :"+results , Toast.LENGTH_LONG)
.show();
Toast.makeText(getApplicationContext(),
"length1 :"+length , Toast.LENGTH_LONG)
.show();
Log.i("length1",length +"");
XYMultipleSeriesRenderer renderer = getTruitonBarRenderer(results.size());
myChartSettings(renderer);
/* Intent intent1 = ChartFactory.getBarChartIntent(WifiChartsRealTime.this,getTruitonBarDataset(),renderer,Type.DEFAULT);
startActivity(intent1);*/
GraphicalView mChartView = ChartFactory.getBarChartView(WifiChartsRealTime.this, getTruitonBarDataset( results), renderer, Type.STACKED);
layout.addView(mChartView);
// mChartView.refreshDrawableState();
mChartView.repaint();
}
}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_wifi_charts_real_time);
layout = (LinearLayout) findViewById(R.id.chart);
ConnectivityManager cxMgr = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
wifi = (WifiManager)getSystemService(Context.WIFI_SERVICE);
Receiver receiver = new Receiver();
registerReceiver(receiver,new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION));
registerReceiver(receiver,new IntentFilter(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION));
