Editor to share with you what attributes Android has, I hope you will gain something after reading this article. Let's discuss it together.

Android:marqueeRepeatLimit= "marquee_forever" / / indicates that scrolling does not stop

The android:descendantFocusability= "blocksDescendants" / / indicates that the child control is shielded from getting focus / so that the parent control item can get focus.

Android:fadingEdge= "none" / / sets the direction in which the border decreases when pulled

The orientation of the gradual change of the border. None (border color unchanged), horizontal (horizontal color lighter), vertical (vertical color lighter).

Android Development: the role of android:fadingEdge attribute in View

Sets the orientation of the border gradient when you pull the scroll bar. None (border color unchanged), horizontal (horizontal color lighter), vertical (vertical color lighter).

ListView is a commonly used display control. The default background is the same transparent color as the system window. If you add a background picture or background color to the ListView, the listView will blacken when scrolling.

The reason is that when scrolling, the view in the list is redrawn using the system's default transparent color, with a color value of # FF191919

To change this, simply call listView's setCacheColorHint (0) and set the color value to 0

Or the attribute Android:cacheColorHint= "# 00000000" of listView in the xml file will be fine.

When scrolling, there will be no background color when redrawing the View.

Android:listSelector= "# 00000000"

After making the above settings, there will be no phenomenon when ListView clicks item.

The fourth divider property, which is used to set a picture as an interval between each item, or to remove the dividing line android:divider= "@ drawable/list_driver" between item.

What's the difference between android:editable and android:enabled? Editext: whether the android:editable setting is editable. If its value is "true", how can it be edited? if "false", how can it not be edited? Whether the android:enabled setting is available, if its value is: "true" how is available, if "false" how the entire edit box is not available. The former modifies only a single attribute, while the latter modifies the whole.

Is android:clickable= "false" clickable like a button?
