如何创建一个widget只需要3步
1、定义一个广播接收者继承AppwidgetProvider
2、在清单文件中配置广播接收者

<receiver android:name=
"ExampleAppWidgetProvider"
>
<intent-filter>
</action></intent-filter>
<meta-data android:name=
"android.appwidget.provider"
android:resource=
"@xml/example_appwidget_info"
>
</meta-data></receiver>
|
3、建立一个xml文件夹存放资源example_appwidget_info.xml
|

|
</appwidget-provider>
|
4、自定义布局example_appwidget的内容

总结: 不要记生命周期调用的先后顺序.
|

|
onenable 方法什么时候调用
ondisabled 方法什么时候调用
onupdate方法 在每次创建新的widget的时候都会调用 , 并且当时间片到的时候也会调用
|
创建widget模板
