android,view的执行过程onDraw、onSizeChanged,onFinishInflate

android,view的执行过程onDraw、onSizeChanged,onFinishInflate - 夏天的风的日志 - 网易博客

小试view的执行过程,此是入门,高手绕道。

 

--------------------------------------------------------------------------------

此为抛砖引玉,个人看官自己发挥。

结果如下:

12-05 22:23:03.587: D/mDebug(9715): TestView context, attrs=@2131034112

12-05 22:23:03.597: D/mDebug(9715): onFinishInflate

12-05 22:23:03.667: D/mDebug(9715): onSizeChanged,w=240,h=282,oldw=0,oldh=0

12-05 22:23:03.727: D/mDebug(9715): onDraw

12-05 22:23:03.757: D/mDebug(9715): onDraw

 

 

 

public class TestView extends View {

 

         public TestView(Context context) {

                   super(context);

                   Log.d("mDebug", "TestView context");

         }
