如何自动录制30秒视频并通过单击按钮通过电子邮件发送

Question

在这个项目中，首先我们必须保存特定人员的电话号码和邮件ID。当单击图像按钮时，我们需要获取30秒的视频，它直接发送到该人设置的邮件ID自动。但是我们无法在单击按钮时获得这两个操作。在这里，我们使用两个按钮进行这两个进一步的操作。因此，请帮助我们在单击按钮时获得这两个操作。

Answer 1

查看您的代码并假设对所有按钮的单独单击运行良好，这就是您必须做的，

1. 将 button4.setOnClickListener 中的电子邮件代码 pre4sent 移动到一个单独的方法，比如 emailRecordng（）

2. 从 onActivityResult 调用此方法 在 *if（resultCode==RESULT_CANCELED）*
   块。

这样，当您单击图像按钮时，它将首先为您录制语音，然后直接从您的onActivityResult（）通过电子邮件发送

让我知道这是否有帮助
