當我嘗試開始活動時，電話停止振鈴，並強制關閉所有的時間。開始活動
所以這裏是我的廣播reciever
public class Incoming extends BroadcastReceiver {
@Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
MyPhoneStateListener phoneListener=new MyPhoneStateListener();
TelephonyManager telephony = (TelephonyManager)
arg0.getSystemService(Context.TELEPHONY_SERVICE);
phoneListener.context = arg0;
telephony.listen(phoneListener,PhoneStateListener.LISTEN_CALL_STATE);
}
}
，這應該開始活動
public class MyPhoneStateListener extends PhoneStateListener {
int prevstate;
public void onCallStateChanged(int state,String incomingNumber){
if(prevstate==TelephonyManager.CALL_STATE_OFFHOOK && state == TelephonyManager.CALL_STATE_IDLE){
Log.i("PARm","Here the activity should start");
}
else if(prevstate==TelephonyManager.CALL_STATE_RINGING && state == TelephonyManager.CALL_STATE_IDLE){
Log.i("PARM","Here the activity should start");
}
switch(state){
case TelephonyManager.CALL_STATE_IDLE:
Log.d("DECallNoteActivity.get getContext();BUG", "IDLE");
prevstate = state;
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.d("DEBUG", "OFFHOOK");
prevstate = state;
break;
case TelephonyManager.CALL_STATE_RINGING:
Log.d("DEBUG", "RINGING");
prevstate = state;
break;
}
}
}
我會很高興，如果你能告訴我怎麼去語境在這種情況下，開始活動或另一種方式如何啓動它。
謝謝。
請發佈任何logcat錯誤。 – Sam
您的BroadcastReceiver如何設置？在清單中使用標記或使用Context.registerReceiver（）？ –
