Android反射类用法调用系统截屏

可以使用以下代码调用系统截屏：

try {
    Class<?> serviceManager = Class.forName("android.os.ServiceManager");
    Method getService = serviceManager.getMethod("getService", String.class);
    IBinder binder = (IBinder) getService.invoke(null, "screenshot");
    Class<?> stub = Class.forName("android.view.IWindowManager$Stub");
    Method asInterface = stub.getMethod("asInterface", IBinder.class);
    Object service = asInterface.invoke(null, binder);
    Method screenshot = service.getClass().getMethod("takeScreenshot");
    Bitmap screenshotBitmap = (Bitmap) screenshot.invoke(service);
    // Do something with the screenshotBitmap
} catch (Exception e) {
    e.printStackTrace();
}

这段代码使用了反射来调用系统服务，获取截屏的 Bitmap 对象。
