talkback

I have a custom view that captures the user's signature ( John Hancock ). I want our application to be as accessible as possible, so I'm taking special care to ensure to optimize our screens for TalkBack and Explore-by-Touch . Since Explore-by-Touch changes all one finger gestures into two finger gestures, it breaks the custom signature view. What I'd like to do is have Explore-by-Touch announce the view's content description on hover, then enable the view when the user double-taps. This will allow them to draw on top of the view with a single pointer like a normal user. I've searched around

I have an unlock screen where the user is prompted to enter a four digit pin. If the user enters their pin incorrectly, a previously invisible TextView is shown with an error message. At this point it would be useful for TalkBack to read the contents of the error message out loud. Through some experimentation, I realized I could set android:focusableInTouchMode="true" on the view and programmatically call View#requestFocus() . This works the first time, but fails on subsequent errors since the view already has focus. Also it seems like a bad idea in general to override the current view focus.

I have a view that has a long press action handler. I use the content description to set the message Talkback speaks when the view gets focus. Currently it says my content description right after getting a focus, and after a short pause says: Double tap to activate, double tap and hold for long press I want to change this message into something like Double tap to "action 1" , double tap and hold for "action 2" Is there a way to do so? I looked into onPopulateAccessibilityEvent() , it gets TYPE_VIEW_ACCESSIBILITY_FOCUSED event, but I wasn't able to change the desired message. Am I missing

I am developing an accessible android application where people would be using Explore by Touch and TalkBack accessibility services to use my application. This is my Android XML code: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/LinearLayout" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TextView android:id="@+id/forename" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="20dip" android:layout_marginLeft="15dip" android:textSize="20sp" android

I'm developing an application that uses TalkBack to guide people through it. However, in those situations I want to have some subtile differences in the layout of the application so navigation is easier and also have extra voice outputs (with TextToSpeech) to help guide the user. My problem is that I only want those changes and extra outputs if the user has TalkBack active. Is there any way to know if it is? I didn't find anything specific to access TalkBack settings directly, but I was hoping there was some form of accessing general phone settings that could let me know what I need. Regards
