大家好我基本上在将2个按钮转换为1时遇到问题。 我有一个用于将图像上载到数据库的按钮，另一个用于将数据也上传到数据库。 这里是我的代码：Android Studio上传按钮和提交按钮1

我试图转移内部bsubmit.onclicklistener代码，还试图改变的提交和上传按钮的代码，但至今没有成功。 对不起noob问题的家伙，我实际上是Android Studio的新手，并且无法适应。 我会继续尝试不同的代码，也许从头开始，但如果你们能帮助我，那会很棒。谢谢：d

您面临的问题是什么？ –

无法找出您的问题或您的要求 –

基本上，我有2个按钮，一个用于上传图片，另一个用于数据上传到数据库。 我试图将2个按钮转换为1，这样当我点击按钮时，我将能够同时上传图片和数据在数据库中。 –
