นี่คือสิ่งที่ฉันใช้ทำสิ่งนี้:
Manifest:
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
<!--This part is inside the application-->
<receiver android:name=".CallReceiver" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
เครื่องตรวจจับการโทรที่นำมาใช้ใหม่ของฉันได้

จากนั้นให้ใช้เพียงแค่คลาสที่ได้รับมาจากนั้นใช้ฟังก์ชั่นง่าย ๆ ไม่กี่อย่าง
public class CallReceiver extends PhonecallReceiver {
@Override
protected void onIncomingCallReceived(Context ctx, String number, Date start)
{
//
}
@Override
protected void onIncomingCallAnswered(Context ctx, String number, Date start)
{
//
}
@Override
protected void onIncomingCallEnded(Context ctx, String number, Date start, Date end)
{
//
}
@Override
protected void onOutgoingCallStarted(Context ctx, String number, Date start)
{
//
}
@Override
protected void onOutgoingCallEnded(Context ctx, String number, Date start, Date end)
{
//
}
@Override
protected void onMissedCall(Context ctx, String number, Date start)
{
//
}
}
