推荐答案

默认情况下，您可以使progressBar可见并在不需要时将其隐藏，如下所示:

By default you can make progressBar visible and hide it when not needed like this:

progressBar.setVisibility(View.GONE);

如果要以编程方式对其进行控制，则可以使用以下方法实现:

If you want to control it programatically then you can achieve that with:

progressBar.setVisibility(View.VISIBLE); //to show
progressBar.setVisibility(View.GONE); // to hide

您甚至可以使用ProgressDialog:

You can even go with ProgressDialog:

private ProgressDialog progressDialog;
...

public void showProgressDialog() {
    if (progressDialog == null) {
        progressDialog = new ProgressDialog(PhotographerDetailActivity.this);
        progressDialog.setIndeterminate(true);
        progressDialog.setCancelable(false);
    }
    progressDialog.setMessage("your message");
    progressDialog.show();
}

public void dismissProgressDialog() {
    if (progressDialog != null ) {
        progressDialog.dismiss();
    }
