如何设置进度条不可知，当文本在我的自动完成中写入时再次可见。android

Question

我已经实现了一个文本观点，所以当我写的东西时，我希望我的进步酒吧变得可见（以及如何使其在oncreate上不可思议）

Answer 1

In order to hide a control such as a ProgressBar in Android use the setVisibility() method like that:

mProgressBar.setVisibility(View.VISIBLE);   // To set it visible

and:

mProgressBar.setVisibility(View.INVISIBLE); // To set it invisible

So just set it to View.INVISIBLE inside your Activity onCreate() method, then set it to View.VISIBLE when you need it to be visible.
