Android 如何将editText数据传递到字符串URL

我想在我的一个activity UploadActivity.java中创建一个url，方法是从另一个activity LoginActivity.java中的3个编辑文本框中获取信息，并将该数据传递到另一个activity

我在这里找到的所有问题都只包含一个静态URL，即www.blahblah.com/blah blah.asp？My=Yes等

基本上，用户必须输入他的电子邮件、密码和我公司制作的客户ID，然后必须将其合并为字符串

像这个 公共静态最终字符串上载\u URL= ;

我使用上面的url将用户的位置上传到服务器

我必须声明活动中的编辑文本框吗？因为目前只有我知道活动的XML布局

我在另一个问题中发现了这一点，我不知道如何在代码中实现它

编辑文本

EditText your_edit_text = (EditText) findViewById(R.id.your_id);

从编辑文本中获取用户数据作为休耕

String edit_text_data = your_edit_text.getText().toString();

现在，当您需要将该数据放在url上时。。用这个像

String your_url = "http://www.google.com=" + edit_text_data;

我想在这里的Url在这个字符串中的报价

上传活动JAVA

简而言之，从LoginActivity获取editText值并将其传递给UploadActivity，然后使用该信息在UploadActivity中构建URL

从LoginActivity获取edittext值并将值传递给UploadActivity

在LoginActivity中的onCreate方法中绑定视图更改ID并通过Intent将输入传递给UploadActivity

使用以上信息在UploadActivity中构建URL

干杯：

您的登录代码在哪里？最好使用比异步任务更好的东西，如okhttp或改型。@AliAhsan登录不是真正的登录对不起，我们只是向我公司的某些客户推出该应用程序，所以身份验证不是很简单，它只是用来保存和加载电子邮件密码和客户ID，我不知道该怎么做，我正在忙着搜索。另外请注意，我大约一周前才开始编写代码，这是android的基本开发，所以我现在还在漂亮的uninformed@PembaTamang，这有什么关系呢？少做样板的朋友非常感谢你，老兄，我会测试代码，让你知道对不起，这只是另一个请求对响应的回应{String clientId=clientId.getText.toString.trim；Intent Intent=new IntentLoginActivity.this，UploadActivity.class；Intent.putExtraclientId，clientId；startActivityintent；}我必须把这个放在哪里…..另外，网络广播的帖子要求上的右侧给了我无法再解决的符号以及登录名。\u URLI添加了响应代码以给出想法，但不要紧，我已经更新了答案。如果您觉得有帮助，请接受并投票。谢谢
