以下は、さまざまなシナリオで発生する状態です。
1)受信した電話に応答する
CALL_STATE_RINGING => CALL_STATE_OFFHOOK (After Answering call) => CALL_STATE_IDLE (After End call)
2)拒否/応答しない(逃した)電話を受けた
CALL_STATE_RINGING => CALL_STATE_IDLE (After End call)
3)電話をかける
CALL_STATE_OFFHOOK (After dialing) => CALL_STATE_IDLE (After End call)
コード
int prev_state=0;
public class CustomPhoneStateListener extends PhoneStateListener {
private static final String TAG = "CustomPhoneStateListener";
@Override
public void onCallStateChanged(int state, String incomingNumber){
if(incomingNumber!=null&&incomingNumber.length()>0) incoming_nr=incomingNumber;
switch(state){
case TelephonyManager.CALL_STATE_RINGING:
Log.d(TAG, "CALL_STATE_RINGING");
prev_state=state;
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.d(TAG, "CALL_STATE_OFFHOOK");
prev_state=state;
break;
case TelephonyManager.CALL_STATE_IDLE:
Log.d(TAG, "CALL_STATE_IDLE==>"+incoming_nr);
NumberDatabase database=new NumberDatabase(mContext);
if((prev_state==TelephonyManager.CALL_STATE_OFFHOOK)){

//Answered Call which is ended
}
if((prev_state==TelephonyManager.CALL_STATE_RINGING)){
prev_state=state;
//Rejected or Missed call
}
break;
}
}
