安卓的AsyncTask给BadTokenException中的ActivityGroup [英] Android AsyncTask give BadTokenException in ActivityGroup
本文介绍了安卓的AsyncTask给BadTokenException中的ActivityGroup的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想下载表的数据，研究背景，所以我没有使用AsyncTask.The preoblem是当单击按钮就应该开始下载。
I want to download table's data in backgroud so i did using AsyncTask.The preoblem is When the button click it should start download.
我觉得有在按钮的点击功能的一些问题，因为我叫inise的 onNextAction（）＆放另一个活动;其他活动的onCreate（）称为AsyncTask的，那个时候我也得到了同样的错误。
它说LocalActivityManager没有启动
I think there are some issues in button click function, because of I called another activity inise the onNextAction() & other Activity's onCreate() called AsyncTask, that time also I got same error.
Its say LocalActivityManager didn't start
，也可以是问题：它的的ActivityGroup内运行...
OR may be issue in : Its running inside the ActivityGroup...
里面的ActivityGroup如何调用AsyncTask的？
Inside the ActivityGroup how to call AsyncTask?
错误的地方是
@Override
protected void onPreExecute() {
this.dialog.setMessage("Downloading Table Data.......");
this.dialog.show();
myProgress = 0;
}
错误是：

错误的地方是 onNextAction（）＆放大器; 在preExecute（）的 this.dialog.show（）;
Error place is onNextAction() & onPreExecute()'s this.dialog.show();
我的问题是
- 解决方案这...
- 我们不能称之为AsyncTask的按钮点击功能里面？
我知道这个活动是不是开始.....为什么没有启动？我呼吁一切都在同一个活动没有不同的活动......
I know the activity is not started.....why that didn't start?I am calling everything in same activity not different activity...
请帮我...
在此先感谢....
推荐答案
我已经使用这个环节做到了这一点.... <一href="http://stackoverflow.com/questions/4329710/android-asynctask-progressdialog-will-not-open-in-activitygroup">Android: AsyncTask的ProgressDialog不会打开的ActivityGroup
I have done this using this link.... Android: AsyncTask ProgressDialog will not open in ActivityGroup
为此，在活动课中创建一个helper方法：
Create a helper method for this purpose in the activity class:
private Context getDialogContext() {
Context context;
if (getParent() != null) context = getParent();
else context = this;
return context;
}
然后换行
private final ProgressDialog dialog = new ProgressDialog(CheckInActivity.this);
到
private final ProgressDialog dialog = new ProgressDialog(getDialogContext());
