In addition to the methods onMeasure(), onLayout(), and onDraw(), there are other important methods in the lifecycle of an Android widget (View):
onAttachedToWindow()— called when the widget is attached to a window, useful for initializing resources.onDetachedFromWindow()— called when the widget is detached from a window, convenient for releasing resources.onSizeChanged(int w, int h, int oldw, int oldh)— called when the size of the widget changes.onTouchEvent(MotionEvent event)— handling touch events.onFocusChanged(boolean gainFocus, int direction, Rect previouslyFocusedRect)— called when the focus changes.onVisibilityChanged(View changedView, int visibility)— when the visibility of the widget changes.
These methods allow managing the widget's behavior at different moments of its lifecycle and user interaction.
