MaterialEditText长度长时，clearbutton不可点击问题

[hub-zjy1024]

在MaterialEditText中,修改注释掉的几行
private boolean insideClearButton(MotionEvent event) {
float x = event.getX();
float y = event.getY();
int startX = getWidth()-(iconOuterWidth + iconPadding));
int endX= getWidth() ;
//int startX = getScrollX() + (iconLeftBitmaps == null ? 0 : (iconOuterWidth + iconPadding));
//int endX = getScrollX() + (iconRightBitmaps == null ? getWidth() : getWidth() - iconOuterWidth - iconPadding);
int buttonLeft;
if (isRTL()) {
buttonLeft = startX;
} else {
buttonLeft = endX - iconOuterWidth;
}
// int buttonTop = getScrollY() + getHeight() - getPaddingBottom() + bottomSpacing - iconOuterHeight;

int buttonTop = getHeight() - getPaddingBottom() -bottomSpacing - iconOuterHeight;
return (x >= buttonLeft && x < buttonLeft + iconOuterWidth && y >= buttonTop && y < buttonTop + iconOuterHeight);
}
