You need to use a BroadcastReceiver. It should look something like this:
您需要使用广播接收器。它应该是这样的：
public class CallReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
Intent i = new Intent(context, IncomingCallPopup.class);
i.putExtras(intent);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
context.startActivity(i);
}
}

Need to Extend BroadcastReceiver
需要扩展 BroadcastReceiver
public class CallReceiver extends BroadcastReceiver {
公共类 CallReceiver 扩展 BroadcastReceiver {
@Override
public final void onReceive(Context context, Intent intent){
try {
String state =intent.getStringExtra(TelephonyManager.EXTRA_STATE);
String number=intent.getExtras().getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
}
catch (Exception e) {
Log.e(TAG," Exception "+e);
}
}
}
