可能是我,但是当我根据android页面上给出的公式计算最小app小部件大小时,我得不到正确的小部件宽度; 公式如下:
width(n)=(70 xn) - 30
当我想要一个5x1小部件时,正确的宽度将是(5*70) - 30 = 320dp.然而,当在motorola Xoom上测试它时,它解析为4x1小部件.我已经测试了不同的值,400dp对于带有Honeycomb的motorola xoom上的5x1似乎很好,但后来我在常规Galaxy Tab上用Gingerbread测试它然后它解析为6x1(就像人们期望的那样).
这里有两个问题;

我有一个带小部件的手电筒应用程序.小部件用于打开和关闭手电筒,不显示主要活动或任何内容.然而,几个小时后,小部件什么都不做.我的意思是如果你点击它,没有任何反应.我有两个课来完成这个a Provider和a Receiver.

那么,我们如何才能获得与尺寸变化相关的信息?
我有一个AppWidget有2个待定意图.他们大部分时间都在工作,但过了一段时间他们就停止了回应.我唯一能够确定的是,它们在Launcher重启后瘫痪,即我使用Launcher Pro,有时会调整设置并且必须重新启动它.之后他们根本不工作.
这里是我onRecieve()和onUpdate()方法:
