我正在尝试实现类似于真实呼叫者的应用程序。当电话响铃时,使用广播接收器并打开MyCustomDialog活动,我可以获取电话号码。
这是我的接收器类,通过它我可以获取通话状态,即通话开始或结束。在这里,我编写了一些方法,它们在CallReceiver.java中使用。
PhonecallReceiver.java
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import java.util.Date;
public abstract class PhonecallReceiver extends BroadcastReceiver
{
private static int lastState = TelephonyManager.CALL_STATE_IDLE;
private static Date callStartTime;
private static boolean isIncoming;
private static String savedNumber;
@Override
public void onReceive(Context context, Intent intent)
{
try
{
if (intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL"))
{
savedNumber = intent.getExtras().getString("android.intent.extra.PHONE_NUMBER");
}
else
{
String stateStr = intent.getExtras().getString(TelephonyManager.EXTRA_STATE);
String number = intent.getExtras().getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
int state = 0;
if(stateStr.equals(TelephonyManager.EXTRA_STATE_IDLE))
{
state = TelephonyManager.CALL_STATE_IDLE;
}
else if(stateStr.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))
{
state = TelephonyManager.CALL_STATE_OFFHOOK;
}
else if(stateStr.equals(TelephonyManager.EXTRA_STATE_RINGING))
{
state = TelephonyManager.CALL_STATE_RINGING;
}
onCallStateChanged(context, state, number);
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
//Derived classes should override these to respond to specific events of interest
protected void onIncomingCallStarted(Context ctx, String number, Date start){}
protected void onIncomingCallEnded(Context ctx, String number, Date start, Date end){}
public void onCallStateChanged(Context context, int state, String number)
{
if(lastState == state)
{
//No change, debounce extras
return;
}
switch (state)
{
case TelephonyManager.CALL_STATE_RINGING:
isIncoming = true;
callStartTime = new Date();
savedNumber = number;
onIncomingCallStarted(context, number, callStartTime);
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
if (isIncoming)
{
onIncomingCallEnded(context,savedNumber,callStartTime,new Date());
}
case TelephonyManager.CALL_STATE_IDLE:
if(isIncoming)
{
onIncomingCallEnded(context, savedNumber, callStartTime, new Date());
}
}
lastState = state;
}
}

通过实现所有这些,我得到了期望的输出结果。
请指导我如何使此活动对话框可拖动,就像truecaller应用程序的弹出窗口一样。
我正在寻找类似于此图像的对话框,
