我正在尝试在我的应用程序中实现一个选项卡。因此，我必须将活动作为子活动开始。但是当我开始某个儿童活动时出现问题，而不是其他活动。所以也许那个活动有什么东西。当我比较两者时，另一个发生错误的地方是执行异步任务。也许这就是原因。这就是我的日志所说的：

关于此事的任何启示。任何帮助是极大的赞赏。谢谢
[编辑：我的代码]
这是我的MainActivity：
TabSpec clipBoard = tabHost.newTabSpec("FirstActivity");
Intent firstIntent = new Intent(this, GroupTabActivity.class);
clipBoard.setIndicator(view1);
clipBoard.setContent(firstIntent );
TabSpec photos = tabHost.newTabSpec("ProductActivity");
Intent secondIntent = new Intent(this, GroupTabActivity.class);
photos.setIndicator(view2);
photos.setContent(secondIntent );
然后GroupTabActivity extends TabParentActivity
TabParentActivity 扩展到ActivityGroup
public class GroupTabActivity extends ParentTabActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d("## this1", getParent().getClass().getSimpleName());
startChildActivity("ActivityGroup", new Intent(this,ActivityGroup.class));
}
最后，ActivityGroup extends TabParentActivity
public void onButtonClick1(View v){
Intent intent = new Intent(getParent(), FirstActivity.class);
TabParentActivity parentActivity = (TabParentActivity)getParent();
parentActivity.startChildActivity("FirstActivity", intent);
}
public void onButtonClick2(View v){
Intent intent = new Intent(getParent(), ProductActivity.class);
TabParentActivity parentActivity = (TabParentActivity)getParent();
parentActivity.startChildActivity("ProductActivity", intent);
}
在 onclick2 之后我遇到了那个错误。ProductActivity 包含一个异步任务。
在日志中，第 2984 行：在 ProductActivity 中：
@Override
protected void onPreExecute() {
if (mainProgressDialog == null){
mainProgressDialog = ProgressDialog.show(ProductActivity.this, "", getString(R.string.loading));
}else{
if (mainProgressDialog.isShowing()==false){
mainProgressDialog = ProgressDialog.show(ProductActivity.this, "", getString(R.string.loading));
}
}
super.onPreExecute();
}
更新：异步任务：
private class BusinessIdListRequestForEverything2 extends AsyncTask<String, Void, String>{
ApiService service;
String mode = ""; //either all or shop
String indicator = "";
List <BusinessDetailsRequestForEverything2> businessRequestList = null;
int numberOfBusinessRequests = 0;
public String getIndicator() {
return indicator;
}
public void setIndicator(String indicator) {
this.indicator = indicator;
}
public ApiService getService() {
return service;
}
public void setService(ApiService service) {
this.service = service;
}
public BusinessIdListRequestForEverything2(ApiService service){
this.service = service;
businessRequestList = new ArrayList<BusinessDetailsRequestForEverything2>();
}
@Override
protected String doInBackground(String... params) {
service.execute(RequestMethod.POST);
return null;
}
/**
* checks all getBusiness api requests if finished
*
* @return
*/
public boolean isBusinessRequestsFinished(){
boolean retVal = false;
int counter = 0;
if (businessRequestList!=null && businessRequestList.size()>0){
for(BusinessDetailsRequestForEverything2 request: businessRequestList){
if (request.getStatus()==AsyncTask.Status.FINISHED){
counter++;
}
}
if (counter == numberOfBusinessRequests){
retVal = true;
}
}
return retVal;
}
public void stopAllBusinessDetailsRequestEverything(){
if (businessRequestList!=null && businessRequestList.size()>0){
for(BusinessDetailsRequestForEverything2 request: businessRequestList){
if (request.getStatus()==AsyncTask.Status.RUNNING){
request.cancel(true);
}
}
}
}
@Override
protected void onPostExecute(String result) {
try{
String response = service.getResponse();
if (response!=null){
Log.d("fritz", "BusinessIdListRequestForEverything response is "+response);
JSONObject jsonObject = new JSONObject(service.getResponse());
JSONObject project = jsonObject.getJSONObject("project");
JSONArray jsonArray = project.getJSONArray("shops");
if (jsonArray.length() > 0) {
getBusinessIdListRequestForEverythingCounter=0;
getBusinessIdListRequestForEverythingBusinessCount = jsonArray.length();
numberOfBusinessRequests = jsonArray.length();
//clear the businessRequestList
businessRequestList.clear();
//increment offset by limit
getBusinessIdOffset += getBusinessIdLimit;
//empty the businessRequestList
for (int x = 0; x < jsonArray.length(); x++) {
JSONObject temp = jsonArray.getJSONObject(x);
Log.d("fritz", "business id =" + temp.getInt("id"));
//getBusiness(temp.getInt("id"));
//call getBusiness api
MottocoApi projectApi = application.getMottocoApiFactory();
ApiService getBusiness = projectApi.getApi("getBusiness");
getBusiness.addParam("id", String.valueOf(temp.getInt("id")));
BusinessDetailsRequestForEverything2 request = new BusinessDetailsRequestForEverything2(getBusiness);
request.execute();
businessRequestList.add(request);
}
}
}
}catch(Exception e){
e.printStackTrace();
}
super.onPostExecute(result);
}
