android-dialog

问题 Solved: see answer below I am sub-classing Dialog to create a dialog with a custom background. I have added a subclass View to the Dialog and it is drawing the bitmap background and layout correctly. But the buttons will not respond to any touch events. I suspect the LinearLayout has to be loaded in the Dialog class, but I think I have to load it in the view class to draw on top of the bitmap. I am totally new to Android dev, so I apologize for the question. Here is what I am doing: public

问题 I have a java class not activity. From any other activity, I called this class and in that class I created alertdialog builder. In that I inflate data from db. Now In this class, I have other listener and method also. In one of the method, I want to dismiss/cancel this dialog. Like how we do setResult(RESULT_OK, intent); finish(); in any activity, same thing I want to do in class. Code: This method I called from activity. public void showProvidersDialog(long customCategoryId) { categoryId =

问题 I show a DialogFragment from another DialogFragment . I need to set title and a button just next to it. I don't want to reimplement the theme and create a custom view inside DialogFragment 's content view instead of dialog title (because it's error-prone and time wasting). Is it even possible? I tried many API functions, AlertBuilder , ActionBar , this and that, still didn't found anything that fits my needs. 回答1: Try something like this: // Title final int titleId = getResources()

问题 I have an AlertDialog dlgDetails which is shown from another AlertDialog dlgMenu . I would like to be able to show dlgMenu again if the user presses the back button in dlgDetails and simply exit the dialog if he presses outside the dialog.

I am trying to create a derived AlertDialog ( public class AlertDialogDetails

问题 While implementing the new Android M permission model I noticed that the permissions dialog does not respect the theming of my styles.xml. In my styles.xml I override the dialog and alertdialog style like this: <item name="android:dialogTheme">@style/Theme.dialog</item> <item name="android:alertDialogTheme">@style/Theme.dialog</item> Is it possible to change the theming? Or is it because this is a system dialog like in the device settings? 回答1: No, it's not possible. The permissions dialog is
