Displaying a ProgressDialog while waiting for a joined Thread

由 邮差的信 提交于 2020-01-20 08:53:31
问题 In my Activity, I load the content for a list from a DB, and want to display a ProgressDialog while it´s loading. I got both working on it´s own, but if I load the data in a thread (which I should do?), the list is displayed before it´s data is loaded. But if I use join, the ProgressDialog doesnt even appear. How can I combine this? Or is this not possible at all with threads? (AsyncTask maybe?) Here´s the code for reference: final ProgressDialog progressD=ProgressDialog.show

Android控件学习（七）——ProgressDialog

代码接着上文 《Android控件学习（六）——AlertDialog》 编写。 这个控件已经 不推荐使用 了， Android 在 API27 中废弃了 ProgressDialog 。 弃用的原因： ProgressDialog 是浮现在 Activity 上的一层，它阻止了用户的交互，所以不友好。 参考资料： 关于ProgressDialog 一、代码示例 ProgressDialog 也是弹出一个对话框，也能屏蔽掉界面上其他控件。不过这货会显示一个进度条，让用户等待。 @Override public void onClick ( View v ) { switch ( v . getId ( ) ) { case R . id . button : ProgressDialog progressDialog = new ProgressDialog ( MainActivity . this ) ; progressDialog . setTitle ( "This is ProcessDialog" ) ; progressDialog . setMessage ( "加载中..." ) ; progressDialog . setCancelable ( true ) ; progressDialog . show ( ) ; break ; default :

How to display a loading screen while doing heavy computing in Android?

由 China☆狼群 提交于 2020-01-17 04:30:46
问题 I am working on a program that searches the users phone for some date, which takes about 2-3 seconds. While it's computing I want to display a loading screen, so the user knows something indeed is happening. However, when I try to display a loading screen before the computations, nothing is displayed on the screen. This is what I have: ProgressDialog loading= new ProgressDialog(this); loading.setTitle("Loading"); loading.setMessage("Please wait..."); loading.show(); //search stuff loading

Android中进度条

首页xml中代码： 其中style属性设置进度条的样式：如上面设置的进度条为水平的进度条 若不设置默认为圆形进度条。 style="@android:style/Widget.ProgressBar.Small" 设置进度的大小如下截图 还有一种对话框进度条ProgressDialog 在button监听事件里实现如下代码 ProgressDialog progressDialog=new ProgressDialog(MainActivity.this); progressDialog.setTitle(“进度条对话框”); progressDialog.setMessage(“loading…”); progressDialog.setCancelable(true); progressDialog.show(); 这里需要注意的式setCancelable（）里面设置true表示对话框可以按back键退出。而false表示不可以按back键退出。所以我们在实际项目中做好控制。数据加载完必须调用dismiss()方法 关闭，否则它一直存在。 来源： CSDN 作者： NobugAnymore 链接： https://blog.csdn.net/weixin_43551957/article/details/104008199

How to timeout Asynctask and dismiss ProgressDialog?

由 一个人想着一个人 提交于 2020-01-13 04:42:28
问题 I've got a problem and hope you can help me. I've got an Asynctask, which starts uploading data if I press a button in my mainactivity. It works fine except if I've got a slow internet connection. The Asynctask starts a progressdialog and if I've got a slow connection, Asynctask stops but the Progressdialog doesn't disappear because it never reached onPostExecute. Now I'm trying to implement a timeout but can't find a way, so that the progressdialog dismisses to do this. Here is my code:
