Example 1 with AccessibilityDelegate

use of android.view.View.AccessibilityDelegate in project AndroidChromium by JackyAndroid.

the class SearchEngineAdapter method getView.

    // TODO(finnur): There's a tinting bug in the AppCompat lib (see http://crbug.com/474695),
    // which causes the first radiobox to always appear selected, even if it is not. It is being
    // addressed, but in the meantime we should use the native RadioButton instead.
    RadioButton radioButton = (RadioButton) view.findViewById(R.id.radiobutton);
    // On Lollipop this removes the redundant animation ring on selection but on older versions
    // it would cause the radio button to disappear.
    // TODO(finnur): Remove the encompassing if statement once we go back to using the AppCompat
    // control.

    // To improve the explore-by-touch experience, the radio button is hidden from accessibility
    // and instead, "checked" or "not checked" is read along with the search engine's name, e.g.
    // "google.com checked" or "google.com not checked".
