我目前正在执行一个异步任务,以将一些数据发布到API上,问题是当我使用进度对话框时,它将引发异常.异步任务名为“ APIhandler”,它将处理几种类型的案例.
这是构造函数
public APIHandler(Context _ctx,EasyTracker _tracker,String _formType) {
this.ctx = _ctx;
this.tracker = _tracker;
this.formType = _formType;
SharedPreferences prefs = ctx.getSharedPreferences("userInfo", 0);
token = prefs.getString("token","");
memId = prefs.getString("memId","");
if (formType.equals("uploadImg")) {
pd = ProgressDialog.show(ctx, ctx.getResources().getString(R.string.sys_info),ctx.getResources().getString(R.string.publishing));
} else {
pd = ProgressDialog.show(ctx, ctx.getResources().getString(R.string.sys_info),ctx.getResources().getString(R.string.loading));
}
}
这是onpostexecute
@Override
protected void onPostExecute(JSONObject result) {
if (pd != null && pd.isShowing())
pd.dismiss();
}
这是调用APIhandler的方法
new APIHandler(ctx,tracker,"login").execute(ctx,session.getAccessToken());
错误代码(请注意在dialog.show中失败)

如何解决该问题？非常感谢
解决方法:
只需确保在显示对话框之前没有完成SharePicForm活动即可.错误显示显示对话框时,您的SharePicForm活动不存在.也许它已经退出了.
