Android创建桌面快捷方式几种方法

Android在桌面上生成快捷方式有两种情况，一种是直接在桌面直接生成;一种是长按桌面，在弹出的快捷菜单中生成。 <p> 谈谈在桌面上直接生成。个人觉得这个比较爽快，既然都是快捷方式了干嘛还要再隐藏一层呢?当然喜欢桌面干净的就比较喜欢第二个了。</p> <p> 第一个是通过广播(Broadcast)的形式向Luncher发送请求生成快捷方式的。</p> <p> 在网上找到关于这方面的注册信息。</p> <div style="border-bottom:windowtext 0.5pt solid;border-left:windowtext 0.5pt

<p> 所以在我们的manifest.xml文件中，我们需要加入下面这段话：</p> <div style="border-bottom:windowtext 0.5pt solid;border-left:windowtext 0.5pt

首先在注册activity时，需要添加一个action为android.intent.action.CREATE_SHOERTCUT的intentFilter.如下所示：</p> <p> </p> <div style="border-bottom:windowtext 0.5pt solid;border-left:windowtext 0.5pt

</span> <span style="color:#000000;"><</span> <span style="color:#000000;">action android:name</span> <span style="color:#000000;">=</span> <span style="color:#800000;">"</span> <span

接下来就是就是设置快捷方式的图标、名称、事件等属性。这里图表的生成，android里提供了专门的方法来生成。</p> <p> </p> <div style="border-bottom:windowtext 0.5pt solid;border-left:windowtext 0.5pt
