android overlay fragment

Jan 29,  · Now.. the reason that the Button elements below receive the clicks is because by default they have the property android:clickable=true. Our overlay does not, and as such it does not intercept and act on the touches. A simple resolution is to add the clickable property to our overlay view. This intercepts clicks, and prevents the buttons from being triggered. The root view from activities (the view with id openmindse.gat, where the layout you load is set) is a FrameLayout. Instead of using the merge tag I could use a FrameLayout as the root of my file, but then I would just complicate the view hierarchy further needlessly, since a FrameLayout with match_parent width/height inside a FrameLayout is just an useless redundancy.

Android: fragments overlapping issue - Stack Overflow

Edit Page Page History Overview DialogFragment is a specialized Fragment used when you want to display an overlay modal window within an activity that floats on top of the rest of the content. This is typically used for displaying an alert dialog, a confirm dialog, or prompting the user for information within an overlay without having to switch to another Activity.

DialogFragment is now the canonical way to display overlays; using Dialog directly is considered bad practice. Usage The minimum that must be implemented when creating a DialogFragment is either the onCreateView method or the onCreateDialog method. Use onCreateDialog when you just need to construct and configure a standard Dialog class such as AlertDialog to display. Note: The entire guide below requires every fragment related class imported to use the android.

If any imported class FragmentManager, DialogFragment, etc uses the android. Custom View Let's start by providing the code for creating a completely custom dialog based on an XML view. Build Dialog Second, let's take a look at how to build a dialog simply by customizing the available Dialog objects that we can construct, android overlay fragment. For more details about the different types of dialogs, check out the "Things to Note" section below.

Builder getActivity ; alertDialogBuilder. Defines the listener interface with a method passing back data result. Setup a callback when the "Done" button is pressed on keyboard mEditText. If you don't want to enable soft keyboard, you may want to dismiss on android overlay fragment button click or on a keypress instead.

Passing Data to Parent Fragment In certain situations, the a dialog fragment may be invoked within the context of another fragment. For example, a screen has tabs with a form contained in a fragment. The form has an input for selecting dates using a date android overlay fragment in a dialog. In this case, we may want to pass the date back not to android overlay fragment activity but instead to the parent fragment, android overlay fragment.

This data can be passed back directly to the parent fragment: import android. In the dialog fragment, android overlay fragment, before android overlay fragment dismissare you calling listener.

Have you correctly implemented the interface and callback method fired i. Try breakpointing each of those lines to make sure the target fragment is set property and the callback method is being executed.

With that, the two fragments are able to pass data back and forth. Styling a dialog or AlertDialog requires changing several key properties in styles. Check out this stackoverflow post for details, android overlay fragment. To complete the transparent effect, make sure to set the alpha channel of the background colors as outlined here to make any background colors semi-transparent.

Styling with Third-Party Libraries Note that third party material libraries such as material-dialogs can be used to simplify and improve dialog styling as well. In order to use the "material-dialogs" library, you will need to add in maven repository to your build. Your gradle file should look something like this. Sizing Dialogs Runtime Dimensions In certain situations, you may want to explicitly set the height and width of the DialogFragment at runtime during creation, android overlay fragment.

This can be done easily with getDialog. Sizing Android overlay fragment for Soft Keyboard When displaying a dialog that is accepting text input, there can often be limited space on screen because the soft keyboard on screen eats up a lot of room, android overlay fragment.

To account for this, you may want to modify the android:windowSoftInputMode property for the activity within the AndroidManifest. Keep in mind that for either of these to work, the layout of the dialog must be configured to resize properly as the height changes.

Full-Screen Dialog Android overlay fragment other cases, we want the dialog to fill the entire screen. Refer to this post for the customized dialog styles.

Specialized Dialog Types When using the onCreateDialog method there are many built-in Dialog types to take advantage of: AlertDialog - Base dialog that can display a message, an icon and buttons with customized text.

ProgressDialog - Dialog showing a progress indicator and an optional text message TimePickerDialog - Dialog that allows a user to select a time. DatePickerDialog - Dialog that allows a user to select a date.

BottomSheetDialog - Dialog that slides from the bottom. Other dialogs not worth discussing here: 1 2 Displaying a ProgressDialog When running a long running background task, one easy way to notify users the app is loading is to display a Android overlay fragment. Refer to this ProgressDialog tutorial for a code sample.

The dialog progress animation can be customized by supplying your own animation drawable using this tutorial. Check out the CodePath android-view-helpers library for an easier way to create simple alert and progress modals. Displaying Date or Time Picker Dialogs The native date and time pickers for Android are another example of specialized dialog fragments. See this section for more information.

If you wish for the containing activity to receive the date or time selected by the dialog, you should ensure that the Activity implements the respective interface, android overlay fragment.

If we want the date picker to be shown from within another dialog fragment, android overlay fragment, refer to setting a target fragment. For instance, for a date picker fragment, you will want to ensure that the activity implements the OnDateSetListener interface: import java. YEAR, year ; c. The non-support version works identically. Dialogs are just classes that extend DialogFragment and define the android overlay fragment to display in the floating content area.

DialogFragment classes must define an empty constructor as shown in the code samples, android overlay fragment, otherwise the Android system will raise an exception when it attempts to instantiate the fragment. After loading the initial view, the activity immediately shows the dialog using the show method which allows the fragment manager to keep track of the state and gives us certain things for free such as the back button dismissing the fragment.

In the code snippets above, notice the use of requestFocus and input modes to control the appearance of the soft keyboard when the dialog appears. We can dismiss a dialog one of two ways. Here we are calling dismiss within the Dialog class itself. It could also be called from the Activity like the show method.

android overlay fragment


I may be very late to answer this question. Note: This answer may not be related to the above question, But hope it will help for some. Sometimes, Fragment overlap issue occurs when we try to use the different type of fragments(i.e using support fragment's in few fragments and normal fragments in someother fragment). 1 Answer. Ok so this might seem like a lot of code, but it's really easy. First, you will create the dialog layout you want in XML. (not in the same XML as the activity view) Here's an example. The root view from activities (the view with id openmindse.gat, where the layout you load is set) is a FrameLayout. Instead of using the merge tag I could use a FrameLayout as the root of my file, but then I would just complicate the view hierarchy further needlessly, since a FrameLayout with match_parent width/height inside a FrameLayout is just an useless redundancy.
