How to access editText in MaterialDialog and perform typing (Android ui test) -
this code
@runwith(androidjunit4.class) @largetest public class changetextbehaviortest { public static final string string_to_be_typed = "espresso"; @rule public activitytestrule<landingactivity> mactivityrule = new activitytestrule<> ( landingactivity.class ); @test public void changetext_sameactivity () { string testtext = "testtext"; onview ( withid ( r.id.action_a) ) .perform ( click (), closesoftkeyboard () ); onview ( withhint ( r.string.add_list ) ).perform ( typetextintofocusedview ( testtext ) ); onview ( withtext ("add" ) ).perform ( click () ); } first need click on floatingbutton open materialdialog
then try access edittext reference hint
onview ( withhint ( r.string.add_list ) ).perform ( typetextintofocusedview ( testtext ) ); but test got error. seem dialog not in view hierarchy.

i can think of 2 possible causes:
1) might dialog still transitioning , espresso not consider visible. or not yet attached.
sometime espresso fails way - if promises wait until main thread idle, sometime doesn't work.
when need actions on dialogs use couple of helper methods wait little bit transitions , whatnot finish. (code below)
2) espresso searching view on wrong root view
click on view in material dialog (using same lib you)
public void test() { // opens time picker dialog onview(withid(r.id.block_edit_start_time)).perform(click()); // click on dialog ok button performmaterialdialogokclick(); } /** * clicks positive button in visible/active {@link com.afollestad.materialdialogs.materialdialog} */ public static void performmaterialdialogokclick() { onview(withid(r.id.buttondefaultpositive)).inroot(isdialog()).perform(click()); } waiting transitions complete
public void test() { // open screen goto(new xyzscreen(datetime.now(), null)); // wait time transitions complete onview(isroot()).perform(waitatleast(300)); // can screenshot screenshot(d); } /** * perform action of waiting specific time. useful when need * wait animations end , espresso fails @ waiting. * <p/> * e.g.: * onview(isroot()).perform(waitatleast(sampling.seconds_15)); * * @param millis * @return */ public static viewaction waitatleast(final long millis) { return new viewaction() { @override public matcher<view> getconstraints() { return anything(); } @override public string getdescription() { return "wait @ least " + millis + " millis."; } @override public void perform(final uicontroller uicontroller, final view view) { uicontroller.loopmainthreaduntilidle(); uicontroller.loopmainthreadforatleast(millis); } }; } /** * perform action of waiting until ui thread free. * <p/> * e.g.: * onview(isroot()).perform(waituntilidle()); * * @return */ public static viewaction waituntilidle() { return new viewaction() { @override public matcher<view> getconstraints() { return anything(); } @override public string getdescription() { return "wait until ui thread free"; } @override public void perform(final uicontroller uicontroller, final view view) { uicontroller.loopmainthreaduntilidle(); } }; }
