我试图从循环中调用 AsyncTask 并为我的 AsyncTask 更新类 varbile。
我的问题是programPosition
不更新是真正的价值,只给我是
循环中的最后一个值。
观看我的 logcatprogramPosition
在我的循环中得到更新,但我的 AsyncTask 得到了
只有最后一个值programPosition
感谢您的帮助。
这是我的代码和我的日志猫:
class CreateNewWorkout extends AsyncTask<String, Void, Void> {
/**
* Before starting background thread Show Progress Dialog
* */
@Override
protected void onPreExecute() {
super.onPreExecute();
if(pDialog != null && pDialog.isShowing() == false)
{
pDialog = new ProgressDialog(DatePage.this);
pDialog.setMessage("Saving...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
}
/**
* Creating product
* */
protected Void doInBackground(String... args) {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
String[] list = dataPorgram.getExParameter("" + programPosition);
Log.d("programPosition", ""+programPosition);
params.add(new BasicNameValuePair("exercise", list[0]));
params.add(new BasicNameValuePair("weight", list[1]));
params.add(new BasicNameValuePair("reps", list[2]));
// getting JSON Object
// Note that create product url accepts POST method
JSONObject json = jsonParser.makeHttpRequest(url_create_food,
"POST", params);
if (json == null) {
Log.d("is null", "null");
return null;
}
// check log cat fro response
Log.d("Create Response", json.toString());
// check for success tag
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// successfully created product
Log.d("ok", json.toString());;
} else {
// failed to create product
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(Void file_url) {
if(pDialog != null)
pDialog.dismiss();
}
}
这是我在其他方法中使用的循环
for (int j = 0; j < arrayLength2; j++) {
String weight = "";
if (helping > 0)
{
check1 = true;
check2 = true;
}
if (allWeights[j][2] == 0) {
double temp;
if (check1)
temp = allWeights[j][0] + (allWeights[j][1]);
else
temp = allWeights[j][0];
allWeights[j][0] = temp;
DecimalFormat df = new DecimalFormat("#.##");
weight = df.format(temp);
if (temp == 0)
weight = "";
else
weight = df.format(temp);
}
else if (allWeights[j][1] == 0) {
double temp;
if (check2)
temp = allWeights[j][0] + (allWeights[j][2] / 100)
* allWeights[j][0];
else
temp = allWeights[j][0];
allWeights[j][0] = temp;
DecimalFormat df = new DecimalFormat("#.##");
if (temp == 0)
weight = "";
else
weight = df.format(temp);
Log.d("weight is ", ""+temp);
}
programPosition = dataPorgram.setProgramPlan(today,selectedDay, weight, j);
Log.d("programPosition", ""+programPosition);
new CreateNewWorkout().execute();
