This time we are going deep into viewgroup, understanding the work of viewgroup, and will explain more about the view of the relevant knowledge. In order to be flexible in the future use of custom space beatings a step closer to the foundation. Want to have like-minded friends to explore, deep inside Android, in-depth understanding of Android. First, what is Vie

Android stores and loads local files (external storage devices) and android storage devices Sometimes the application needs to write data to the external storage of the device. If you want to share music, images, or online data with other apps or users, it is easier to share data stored on external devices. In addition, external devices usually have larger storag

full custom or inherited view derived subclasses You must provide a constructor that gets the context and the AttributeSet object as a property, gets the property, and when view is created from the XML layout, All attributes in the XML tag are read from the resource bundle and passed as a attributeset to the view's constructor. View derived direct or indirect

Android custom view implementation is simple Inherit view, override constructors, ondraw, (onmeasure) and other functions. If a custom view requires custom attributes, you must create attrs. xml under values. Define your attributes. Add xmlns: prefix = "http://schemas.android.com/apk/res/your custom
