內活動我想在我的onReceive()
方法啓動的活動。開始的onReceive廣播接收器
package com.splashscreenactivity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.Toast;
public class SMSReceiver extends BroadcastReceiver {
public static String trigger_message = "";
@Override
public void onReceive(Context context, Intent intent) {
// ---get the SMS message passed in---
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
String str = "";
if (bundle != null) {
// ---retrieve the SMS message received---
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for (int i = 0; i < msgs.length; i++) {
msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
str += "SMS from " + msgs[i].getOriginatingAddress();
str += " :";
trigger_message = msgs[i].getMessageBody().toString();
str += trigger_message;
str += "\n";
}
// ---display the new SMS message---
Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
if (trigger_message.equals("dx")) {
Toast.makeText(context, "I am triggered", Toast.LENGTH_LONG)
.show();
// /////////////////////////
// i want to start here
// ////////////////////////
// MainScreenActivity.trigger="Now";
// Intent i = new Intent(context,GPS.class);
// i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// context.startActivity(i);
} else {
Toast.makeText(context, "I am not triggered, Bbyz!!!",
Toast.LENGTH_LONG).show();
}
}
}
}
這裏是GPS.class
package com.splashscreenactivity;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.telephony.SmsMessage;
import android.widget.TextView;
import android.widget.Toast;
public class GPS extends Activity implements LocationListener {
TextView latitude, logitude;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.gps);
LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000L, 500.0f,
this);
Toast.makeText(this, "i m started", Toast.LENGTH_LONG);
// latitude = (TextView)findViewById(R.id.txtLat);
// logitude = (TextView)findViewById(R.id.txtLongi);
// latitude.setText("Loading...");
// logitude.setText("Loading...");
}
String LATTITUDE;
String LOGITUDE;
@Override
public void onLocationChanged(Location location) {
double lat = location.getLatitude();
double lag = location.getLongitude();
LATTITUDE = Double.toString(lat);
LOGITUDE = Double.toString(lag);
// latitude.setText(LATTITUDE);
// logitude.setText(LOGITUDE);
// SmsManager sm = SmsManager.getDefault();
// // here is where the destination of the text should go
// String number = "5556";
// sm.sendTextMessage(number, null,
// "latitude="+latitude.getText()+"\nlongitude="+logitude.getText(),
// null, null);
}
@Override
public void onProviderDisabled(String arg0) {
}
@Override
public void onProviderEnabled(String arg0) {
}
@Override
public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
}
// /** Register for the updates when Activity is in foreground */
// @Override
// protected void onResume()
// {
// super.onResume();
// lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000L, 500.0f,
// this);
// }
//
// /** Stop the updates when Activity is paused */
// @Override
// protected void onPause() {
// super.onPause();
// lm.removeUpdates(this);
// }
}
有什麼問題你得到? –
您已擁有啓動活動的代碼。只是取消它的評論。 – jamapag
其實startActivity方法不是在上接收方法的工作,因爲這不是階級從logcat中取消註釋該代碼I M獲得強制退出在我的模擬器 –
