Click on EditText's drawable right with Espresso

How could be possible to click on EditText's right drawable (check the screenshot)? I have tried several ways but I always get stuck.

public static Matcher<View> withEditTextDrawable(final int resourceId) {
    return new BoundedMatcher<View, EditText>(EditText.class) {
        @Override
        protected boolean matchesSafely(final EditText editText) {
            // ????

            return false;
        }

        @Override
        public void describeTo(Description description) {
            description.appendText("with drawable from resource id: ");
            description.appendValue(resourceId);
        }
    };
}

Had to develop this custom action and matcher to test our discard drawables on the right of some text fields, discard edittext this will click any drawable (left, top, right, bottom) of a TextView in an Espresso test.

Usage:

onView(withId(id)).perform(clickDrawables());

Method:

public static ViewAction clickDrawables()
{
    return new ViewAction()
    {
        @Override
        public Matcher<View> getConstraints()//must be a textview with drawables to do perform
        {
            return allOf(isAssignableFrom(TextView.class), new BoundedMatcher<View, TextView>(TextView.class)
            {
                @Override
                protected boolean matchesSafely(final TextView tv)
                {
                    if(tv.requestFocusFromTouch())//get fpocus so drawables become visible
                        for(Drawable d : tv.getCompoundDrawables())//if the textview has drawables then return a match
                            if(d != null)
                                return true;

                    return false;
                }

                @Override
                public void describeTo(Description description)
                {
                    description.appendText("has drawable");
                }
            });
        }

        @Override
        public String getDescription()
        {
            return "click drawables";
        }

        @Override
        public void perform(final UiController uiController, final View view)
        {
            TextView tv = (TextView)view;
            if(tv != null && tv.requestFocusFromTouch())//get focus so drawables are visible
            {
                Drawable[] drawables = tv.getCompoundDrawables();

                Rect tvLocation = new Rect();
                tv.getHitRect(tvLocation);

                Point[] tvBounds = new Point[4];//find textview bound locations
                tvBounds[0] = new Point(tvLocation.left, tvLocation.centerY());
                tvBounds[1] = new Point(tvLocation.centerX(), tvLocation.top);
                tvBounds[2] = new Point(tvLocation.right, tvLocation.centerY());
                tvBounds[3] = new Point(tvLocation.centerX(), tvLocation.bottom);

                for(int location = 0; location < 4; location++)
                    if(drawables[location] != null)
                    {
                        Rect bounds = drawables[location].getBounds();
                        tvBounds[location].offset(bounds.width() / 2, bounds.height() / 2);//get drawable click location for left, top, right, bottom
                        if(tv.dispatchTouchEvent(MotionEvent.obtain(android.os.SystemClock.uptimeMillis(), android.os.SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, tvBounds[location].x, tvBounds[location].y, 0)))
                            tv.dispatchTouchEvent(MotionEvent.obtain(android.os.SystemClock.uptimeMillis(), android.os.SystemClock.uptimeMillis(), MotionEvent.ACTION_UP, tvBounds[location].x, tvBounds[location].y, 0));
                    }
            }
        }
    };
}



This is a refinement I made to select a specific drawable to click:

Usage:

onView(withId(id)).perform(new ClickDrawableAction(ClickDrawableAction.Right));

Method:

public static class ClickDrawableAction implements ViewAction
{
    public static final int Left = 0;
    public static final int Top = 1;
    public static final int Right = 2;
    public static final int Bottom = 3;

    @Location
    private final int drawableLocation;

    public ClickDrawableAction(@Location int drawableLocation)
    {
        this.drawableLocation = drawableLocation;
    }

    @Override
    public Matcher<View> getConstraints()
    {
        return allOf(isAssignableFrom(TextView.class), new BoundedMatcher<View, TextView>(TextView.class)
        {
            @Override
            protected boolean matchesSafely(final TextView tv)
            {
                //get focus so drawables are visible and if the textview has a drawable in the position then return a match
                return tv.requestFocusFromTouch() && tv.getCompoundDrawables()[drawableLocation] != null;

            }

            @Override
            public void describeTo(Description description)
            {
                description.appendText("has drawable");
            }
        });
    }

    @Override
    public String getDescription()
    {
        return "click drawable ";
    }

    @Override
    public void perform(final UiController uiController, final View view)
    {
        TextView tv = (TextView)view;//we matched
        if(tv != null && tv.requestFocusFromTouch())//get focus so drawables are visible
        {
            //get the bounds of the drawable image
            Rect drawableBounds = tv.getCompoundDrawables()[drawableLocation].getBounds();

            //calculate the drawable click location for left, top, right, bottom
            final Point[] clickPoint = new Point[4];
            clickPoint[Left] = new Point(tv.getLeft() + (drawableBounds.width() / 2), (int)(tv.getPivotY() + (drawableBounds.height() / 2)));
            clickPoint[Top] = new Point((int)(tv.getPivotX() + (drawableBounds.width() / 2)), tv.getTop() + (drawableBounds.height() / 2));
            clickPoint[Right] = new Point(tv.getRight() + (drawableBounds.width() / 2), (int)(tv.getPivotY() + (drawableBounds.height() / 2)));
            clickPoint[Bottom] = new Point((int)(tv.getPivotX() + (drawableBounds.width() / 2)), tv.getBottom() + (drawableBounds.height() / 2));

            if(tv.dispatchTouchEvent(MotionEvent.obtain(android.os.SystemClock.uptimeMillis(), android.os.SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, clickPoint[drawableLocation].x, clickPoint[drawableLocation].y, 0)))
                tv.dispatchTouchEvent(MotionEvent.obtain(android.os.SystemClock.uptimeMillis(), android.os.SystemClock.uptimeMillis(), MotionEvent.ACTION_UP, clickPoint[drawableLocation].x, clickPoint[drawableLocation].y, 0));
        }
    }

    @IntDef({ Left, Top, Right, Bottom })
    @Retention(RetentionPolicy.SOURCE)
    public @interface Location{}
}

I solved it using the Material Component TextInputLayout and TextInputEditText

In your xml:

 <com.google.android.material.textfield.TextInputLayout
            style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
            android:id="@+id/til_location"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:endIconMode="custom"
            app:endIconDrawable="@drawable/ic_edit_location"
            app:endIconTint="@color/colorAccent"
            app:hintEnabled="false"
            app:endIconContentDescription="open map icon">

            <com.google.android.material.textfield.TextInputEditText
                android:id="@+id/et_address"
                android:textColor="@color/colorAccent"
                android:layout_height="wrap_content"
                android:layout_width="match_parent"
                tools:text="3 streenasdasdasd"/>

        </com.google.android.material.textfield.TextInputLayout>

The trick here is to set the app:endIconMode="custom" then add your drawable as u want.

In java class:

you can use the setEndIconOnClickListener and do what you want as below:

tilLocation.setEndIconOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            //do click
        }
    });
