Android TalkBack EditText - hint vs. contentDescription

Question

I have a TextView and an EditText. The TextView uses android:labelFor="@+id/EditTextId";

The EditText also has a hint that represents and example of input, that I only want to be visible for the users that do not use TalkBack, and not be read by the TalkBack.

android:contentDescription="Mandatory field" android:hint="Example of input"

The TalkBack would usually read (how I want it to work):

"Mandatory field, Edit Box for Text View"

but instead, reads:

"Example of input, Edit Box for Text View"

Answer 1

This was possible by doing:

View.AccessibilityDelegate accessibilityDelegate = new View.AccessibilityDelegate() {
            @Override
            public void onInitializeAccessibilityNodeInfo(View v, AccessibilityNodeInfo info) {
                super.onInitializeAccessibilityNodeInfo(v, info);
                info.setText("Mandatory field");
            }
        };

        myEditTex.setAccessibilityDelegate(accessibilityDelegate);

This way, the accessibility TalkBack will read: "Mandatory field " + "Edit box for " + the TextView that has android:labelFor
