AndroidJava– 删除顺序加载动画延迟

概述我有一个android动画,它加载了一系列顺序点(publishProgress),但是在它们启动之前有10秒的延迟因为我将它们作为我的AsyncTask的一部分,它在数据处理时加载(技术上–两者应该是相关的)–但它在视觉上会导致延迟)如何在课程首次启动时调用此动画？我需要删除这个可视动画延迟.资

解决方法:

您可以使用AsyncTask中的onPreExecute()和onPostExecute()方法在工作完成之后设置加载/删除它.

尝试：

protected voID onPreExecute() {           setProgressimgVIEw(R.drawable.loading_full,                            R.drawable.loading_empty, R.drawable.loading_empty,                            R.drawable.loading_empty, R.drawable.loading_empty);}protected voID onPostExecute(inputStream stream) {           setProgressimgVIEw(R.drawable.loading_full,                        R.drawable.loading_full, R.drawable.loading_full,                        R.drawable.loading_full, R.drawable.loading_full);    // This method is called to parse the response and save the    // ArrayLists    success();}
