get Variable in doInBackground Get out of AsyncTask

Question

如何在doInBackground中获取变量 退出 AsyncTask

请求 API 网址设置新的喜欢并获取新的喜欢和喜欢模式

现在如何从 AsyncTask 中获取新的喜欢和喜欢模式以使用 setText

从 GetDataLike AsyncTask 中得到这样的结果：

new GetDataLike().execute(textViewQuoteId.getText().toString());
String newLike = GetDataLike().newLike; // get like this from GetDataLike
String modeLike = GetDataLike().modeLike; // get like this from GetDataLike
textViewQuoteLike.setText("پسندیدم ("+newLike+")");
Toast.makeText(rootView.getContext(), "لایک شما برای سخن "+textViewProfileName.getText().toString()+" ثبت شد.",
Toast.LENGTH_LONG).show();

Json 结果示例：

{"Like":{"quote_like":"27","quote_like_mode":"1"}}

Answer 1

你只需要从doInBackground方法返回字符串，在onPostExecute方法中，你可以设置Text.对于多个值，在这种情况下，你应该这样做

public class CollectValues{ 
public String quote_like;
public String quote_like_mode;}

现在在doInBackground方法中，你应该这样做

CollectValue cv = new CollectValue();
cv.quote_like=//your response;
cv.quote_like=//your response;
return cv;

最后在 onPostExecute 方法中，你应该这样做

@Override
protected void onPostExecute(CollectValues cv) {
//your textview here
textview1.setText(cv.quote_like);
textview2.setText(cv.quote_like_mode);
}

这将解决您的问题。
