在Android中捕获并保存连续图像
这是我的代码,它存储从相机捕获的图片并将其保存在SD卡上,但现在我想将此代码增强为每5秒拍摄一次,如果有人知道如何执行此操作,请与我们分享在Android中捕获并保存连续图像,android,Android,这是我的代码,它存储从相机捕获的图片并将其保存在SD卡上,但现在我想将此代码增强为每5秒拍摄一次,如果有人知道如何执行此操作,请与我们分享 public class MainActivity extends ActionBarActivity { private final int requestCode = 20; @Override protected void onCreate(Bundle savedInstanceState) { supe

您应该实现一个使用线程的可运行接口。通过这种方式,您可以在OnClick方法上调用函数,然后调用Thread.sleep(timeinmillizes),然后根据需要在OnClick方法内再次调用函数 下面是一个如何使用线程的示例:
1。在类的顶部添加可运行的实现。2.创建一个线程。3.call方法4.call thread.sleep()5。再打电话给我,请给我发电子邮件!
