我想知道是否有可能在Android中创建一个活动的多个实例？

我目前使用下面的code开始自己的inCall屏幕用于VoIP测试：

 公共无效initInCallScreen（字符串PNAME，字符串phoneNumber的，诠释的ContactID，布尔
        callDirection，诠释另一LineID）{

    //开始在callScreen对话框
    最终意图myIntent =新的意图（背景下，CallDialogActivity.class）;
    myIntent.putExtra（名，PNAME）;
    myIntent.putExtra（编号，phoneNumber的）;
    myIntent.putExtra（ID，的ContactID）;
    myIntent.putExtra（CALLTYPE，callDirection）; //真=传入，假=传出
    myIntent.putExtra（另一LineID，另一LineID）;
    myIntent.setFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;
    context.startActivity（myIntent）;
 

这让我开始活动就好了。

然而，当我把它一秒钟它只是返回到已创建的，而不是创建一个新的活动，并把它在堆栈上的活动。

我希望能够创建活动多次，让我有堆栈上的两个或3活动，用户可以在它们之间进行切换，使用主页，后退按钮等等...

这是可能的，如果是这样我在做什么错了？

当我把它一秒钟它不过   刚刚返回到活动已经   创建而不是创建一个新的   活动，并把它压入堆栈。

您可能改变了你的清单中添加一个安卓launchMode 属性，它干扰了你的目标。缺省情况下，启动一个活动开始的新实例。

另外：

摆脱 myIntent.setFlags（Intent.FLAG_ACTIVITY_NEW_TASK）; ，因为你根据你在这里写不想要一个新的任务 由于上下文可能是一个上下文，我不知道为什么你要通过所有的 ContextWrapper / getBaseContext（）的东西

I was wondering is it possible to create multiple instances of a single Activity in Android?

I currently start my own inCall screen for a Voip Test by using the following code:

     public void initInCallScreen(String pName, String phoneNumber, int contactID, boolean 
        callDirection, int lineID){

    //starts in callScreen dialog
    final Intent myIntent = new Intent(context, CallDialogActivity.class);
    myIntent.putExtra("NAME", pName);
    myIntent.putExtra("NUMBER", phoneNumber);
    myIntent.putExtra("ID", contactID);
    myIntent.putExtra("CALLTYPE", callDirection); //True = Incoming, False = Outgoing
    myIntent.putExtra("LINEID", lineID);
    myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(myIntent);

This allows me to start the Activity fine.

However when I call it for a second it just returns to the Activity already created rather than creating a new Activity and placing it on the stack.

I would like to be able to create the activity multiple times so that I have two or 3 Activities on the stack and the user can switch between them, using Home, Back buttons etc...

Is this possible and if so what am I doing wrong?

You probably changed your manifest to add an android:launchMode attribute that is interfering with your goal. By default, starting an activity starts a new instance.

Also:

Get rid of myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);, since you do not want a new task based on what you have written here Since context is probably a Context, I do not know why you are going through all of the ContextWrapper / getBaseContext() stuff
