为了显示对话框，您需要从名为的函数返回。那是因为对该调用的实际处理是在消息循环中完成的（该循环首先调用了您的函数）。因此，在您的代码中，您正在创建一个对话框并将其标记为要显示，但永远不会通过在同一函数末尾调用来给它显示自己的机会。 您应该使用。首先，您需要将UI处理代码与功能分开。将所有耗时的东西放在的函数中，所有UI都应在或中。 您可以在功能中显示进度对话框，而在功能中将其关闭。或者，也可以在中显示进度对话框，然后在中隐藏它。 ѭ8有很多示例，其中一个位于AsycnTask android docs中。可以在android开发人员资源中找到另一篇有用的文章：无痛线程。捅瓶啡
final ProgressDialog dialogMatchList = ProgressDialog .show(TennisAppActivity.mContext, \"\", \"Loading. Please wait...\", true); dialogMatchList.setProgressStyle(ProgressDialog.STYLE_SPINNER); dialogMatchList.setIndeterminate(true); dialogMatchList.setCancelable(true);dialogMatchList.setOnDismissListener(new OnDismissListener() { public void onDismiss(DialogInterface arg0) { list.setAdapter(new EfficientAdapter(getApplicationContext())); } });长拳
progressDialog = ProgressDialog.show(CatalogActivity.this, \"\", \"Please wait for few seconds...\", true); runOnUIThread(new Runnable() { public void run() { //Do you task here progressDialog.dismiss(); } });
