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
Had to develop this custom action and matcher to test our discard drawables on the right of some text fields, 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 getConstraints()//must be a textview with drawables to do perform
{
return allOf(isAssignableFrom(TextView.class), new BoundedMatcher(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 getConstraints()
{
return allOf(isAssignableFrom(TextView.class), new BoundedMatcher(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));
}
}
