这个例子首要研究Androidbroadcast播送机制的实现,以一个电池监测及播送告诉为例,介绍了实现broadcast的进程:大致的思路是:注册一个系统BroadcastReceiver,作为访问电池计量之用,假如捕捉到的action是ACTION_BATTERY_CHANGED,就运行onBatteryInfoReceiver(),捕捉到ACTION_BATTERY_CHANGED时要运行的method,创建一个布景含糊的Window,且将对话窗口放在远景,将获得的电池计量显示于Dialog中,设置回来主画面的按钮。

(This example mainly studies the implementation of the Android broadcast mechanism. Taking a battery monitoring and broadcast notification as an example, it introduces the process of implementing the broadcast. The general idea is: register a system BroadcastReceiver for accessing battery metering. If the captured action is ACTION_ BATTERY_ CHANGED, run onBatteryInfoReceiver() to capture ACTION_ BATTERY_ The method to be run when CHANGED, create a window with ambiguous scenery, place the dialog window in the foreground, display the obtained battery measurement in the Dialog, and set the button back to the main screen.)
