我正在尝试在片段内显示进度对话框。但是progressbar.show（）没有任何效果。但是，我注意到一个奇怪的行为，如果我两次调用showPopUp（）方法，它会显示进度对话框，但无法解雇（）。

试试这样：
progressDialog = new ProgressDialog(getActivity());
如果您希望自定义对话框并将自己创建的布局放入其中。
/**
* Created by vivek on 18/10/16.
*/
public class CustomDialog {
private static Dialog dialog;
private static Context context;
public CustomDialog(Context context) {
this.context = context;
}
/**
* Comman progress dialog ... initiates with this
*
* @param message
* @param title
*/
public static void showProgressDialog(Context context, String title, String message) {
if (dialog == null)
{
dialog = new Dialog(context);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.custom_loader);
dialog.setCancelable(false);
dialog.setCanceledOnTouchOutside(false);
dialog.show();
}
}
public static boolean isProgressDialogRunning() {
if (dialog != null && dialog.isShowing()) {
return true;
} else return false;
}
/**
* Dismiss comman progress dialog
*/
public static void dismissProgressDialog() {
if (dialog != null && dialog.isShowing()) {
dialog.dismiss();
dialog = null;
}
}
} // End of main class over here ...
答案 1 :(得分：1)
替换它： -
SELECT regexp_split_to_table(feature, E' \\| ') AS k, count(*)
FROM tab1
GROUP BY k
与
progressDialog = new ProgressDialog(getContext(), ProgressDialog.THEME_HOLO_LIGHT);
答案 2 :(得分：0)
progressdialog以及progressbar这两个{但是当你在那个时候解雇你的progressbar时，在你解雇第一个之前，前一个被其他人覆盖..所以第一个人总是在屏幕上。这就是问题所在。
答案 3 :(得分：0)
我尝试了一切。但没有一个答案解决了这个问题。但是，我通过覆盖片段中的onResume（）方法来解决它。
全部谢谢。
