我想实现当访问数据时就锁定返回按钮。我使用 AsyncTask 来传递数据：
class Process extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute() {
super.onPreExecute();
progDailog = new ProgressDialog(ShareFolderActivity.this.getParent());
progDailog.setMessage("Loading...");
progDailog.setIndeterminate(false);
progDailog.setMax(100);
progDailog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progDailog.setCancelable(true);
progDailog.show();
lock = true;
}
@Override
protected String doInBackground(String... aurl) {
//process
return null;
}
@Override
protected void onPostExecute(String unused) {
super.onPostExecute(unused);
PostLoad();
progDailog.dismiss();
lock = false;
}
}
onBackPressed():
@Override
public void onBackPressed() {
if(!lock) {
//back action
}
}
当 doInBackground 返回按钮被点击时，返回的活动不执行，但是 progDailog 消失。如何修改让progDailog 不消失呢？
