我在android中使用本机sip创建了sip应用程序.在我从sip服务器取消注册帐户时遇到问题,每次我得到 DATA_CONNECTION_LOST.我也在android文档中看到,但是没有对此错误的简要解释.也是面对各种错误,而像in_progress,transaction_terminated等在文档中没有正确解释的regiterin.这是我的代码:

    public SipException sipexeception;
    public static WalkieTalkieActivity walkiy;

    public static WalkieTalkieActivity getInstance(Context c) {

我使用sip调用的本机方法,它工作正常,但有时它给出注册错误IN_PROGRESS(错误代码-9).我在Sip错误代码中搜索但dint找到这种错误代码.这是我的sip注册代码.请告诉我,如果有任何人对这个错误有所了解请告诉我.

我有一个名为“容器” 的LinearLayout内部DrawerLayout。在运行时，我正在尝试RelativeLayout在“容器”中添加一个容器。这会导致RelativeLayout对齐无法正常运行，即进度超过徽标图像。

相对布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    <LinearLayout

我正在开发一个Android应用程序,其中即时通讯使用异步任务和后执行方法,当我关闭进度对话框时,异常即将到来且应用程序正在强制关闭.

例外情况是:

    04-24 09:41:54.661: E/AndroidRuntime(1727): java.lang.IllegalArgumentException: View not attached to window manager
    04-24 09:41:54.661: E/AndroidRuntime(1727):     at android.view.WindowManagerImpl.findViewLocked(WindowManagerImpl.java:355)

代码:

data_insertion = new AsyncTask<Void, Void, Void>() {
  @Override
  protected void onPreExecute() {
    // TODO Auto-generated method stub             
    CommonUtility.show_PDialog(MainActivity.this);
    super.onPreExecute();
  }
  @Override
  protected void onPostExecute(Void result) {

我使用原生sip apis在Android应用程序中实现sip调用,它工作正常,但在一些设备,如CANVAS 3,它没有工作.调试后我发现这行代码返回NULL

 **manager = SipManager.newInstance(ctx);**

这measns该设备不支持SIP Apis.But在同一设备的其他应用sipcalling像SipDroid等正在properly.How这是可能的吗？难道他们不使用本地SIP蜜蜂???

我在listview中使用切片时遇到了问题.我需要使用viewholder使listview滚动顺利,但我不知道如何实现两个视图,因为两个单独的视图一个是节,第二个是简单的条目.这是我尝试的代码和我得到的错误.请告诉我我在哪里做错了,我该如何纠正它:
