如何在我的自定义对话框上显示进度对话框？

Question

我有一个打开的自定义对话框，有一些任务我必须在它上面显示我的进度对话框。但我猜进度对话框显示在我的自定义对话框下方。这是我试过的代码

我的进度对话框代码

KProgressHUD 是第三方库

private void progressDialog() {
    kProgressHUD = new KProgressHUD(getActivity());
    if (!kProgressHUD.isShowing()) {
        kProgressHUD.setStyle(KProgressHUD.Style.SPIN_INDETERMINATE)
                .setLabel("Please wait")
                .setCancellable(false)
                .setAnimationSpeed(2)
                .setDimAmount(0.5f)
                .show();
    }
}

我的自定义对话框代码

final Dialog dialog = new Dialog(consumerHomeActivity);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.custom_dialog_select_vendor);
    dialog.setCancelable(true);
    dialog.setCanceledOnTouchOutside(false);
    Window window = dialog.getWindow();
    window.setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    WindowManager.LayoutParams wlp = window.getAttributes();
    wlp.gravity = Gravity.CENTER;
    window.setAttributes(wlp);

    loadVendorsListFromFirebaseDB(dialog, bookingType);
    dialog.show();

调用进度对话框方法的方法

private void loadVendorsListFromFirebaseDB(final Dialog dialog, final String bookingType) {

    progressDialog();

    final ArrayList<VendorsList> arrayListVendorsList = new ArrayList<>();
    final ListView vendorsListLv = dialog.findViewById(R.id.custom_dialog_select_vendor_list_lv);

    DatabaseReference databaseReferenceVendorsList = firebaseDatabase.getReference("vendorsList");

    databaseReferenceVendorsList.addListenerForSingleValueEvent(new com.google.firebase.database.ValueEventListener() {
        @Override
        public void onDataChange(final com.google.firebase.database.DataSnapshot dataSnapshot) {
            arrayListVendorsList.clear();

            for (DataSnapshot postSnapshot : dataSnapshot.getChildren()) {

                String vendorEmailId = postSnapshot.getKey();
                String vendorName = postSnapshot.child("vendorName").getValue(String.class);

                VendorsList vendorsList = new VendorsList();
                vendorsList.setVendorEmailID(vendorEmailId);
                vendorsList.setVendorName(vendorName);

                arrayListVendorsList.add(vendorsList);

            }

            if (arrayListVendorsList.size() == 0) {
                StaticMethods.customSnackBar(consumerHomeActivity.parentLayout, "Sorry, no vendors available right now",
                        getResources().getColor(R.color.colorPrimaryDark),
                        getResources().getColor(R.color.error_orange), 3000);
            }

            vendorsListAdapter = new VendorsListAdapter(consumerHomeActivity, arrayListVendorsList);
            vendorsListLv.setAdapter(vendorsListAdapter);

            dismissDialog();
        }

        @Override
        public void onCancelled(DatabaseError databaseError) {

        }
    });

}

Answer 1

只需在线条下方滑动

loadVendorsListFromFirebaseDB(dialog, bookingType);
dialog.show();

到

dialog.show();
loadVendorsListFromFirebaseDB(dialog, bookingType);

这是因为您在显示进度对话框后才显示对话框

Answer 2

您在将 Dialog.Use 显示为

之前显示进程对话框

dialog.show();
loadVendorsListFromFirebaseDB(dialog, bookingType);

作为建议使用 DialogFragment 而不是 Dialog。它是一个带有对话框外观的片段，更适合您的需要。

Answer 3

您正在先加载数据列表，然后再显示自定义对话框。因此您的进度对话框不会显示在自定义对话框上。

请如下更改代码以显示第一个自定义对话框并在加载数据列表后显示。

final Dialog dialog = new Dialog(consumerHomeActivity);

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.custom_dialog_select_vendor);
dialog.setCancelable(true);
dialog.setCanceledOnTouchOutside(false);
Window window = dialog.getWindow();
window.setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
WindowManager.LayoutParams wlp = window.getAttributes();
wlp.gravity = Gravity.CENTER;
window.setAttributes(wlp);

dialog.show();
loadVendorsListFromFirebaseDB(dialog, bookingType);
