安卓：是否有可能把用户输入和显示回来？ [英] Android: Is it possible to take user input and display it back?

问题描述

我是新来的这一点，但我试图把用户输入（即用户名），然后在不同的活动显示它通过一个TextView（即显示器将显示这是用户名的举动）。

I'm new to this but I'm trying to take user input (i.e. userName) and then display it in a different activity via a textView (i.e. display will show "it's 'userName's move").

我不知道我是否可以通过java文件分配用户输入一个字符串，然后用我的意图传递数据，或者如果我必须使用某种形式的存储的做到这一点。

I'm not sure if I can do this by assigning the user input to a string in the java file, then passing the data with my intent or if I have to use some form of storage.

无论哪种方式，我仍然困惑，我怎么能得到这个回字符串中的.xml文件显示。

either way, I'm still confused as to how I can get this back to a string in the .xml file to be displayed.

任何帮助将是非常美联社preciated :)

Any help would be much appreciated :) cheers

推荐答案

由于有人指出在评论中，你应该了解的意图是什么。你可以阅读他们这里。作为一个非常简单的例子：

As it was pointed in the comments, you should understand the what an Intent is. You can read about them here. As a very brief example:

Intent launchNewActivity = new Intent(this, NewActivity.class);
launchNewActivity.putExtra("Some key", "Some value"); //sometimes you want to pass extra data
startActivity(launchNewActivity);

此外，这将是很好太了解使用strings.xml中，因为的此处解释。基本上，它是用来定义常量不会硬codeD和您可以在code调用。它们可以帮助你保持你的code有组织，也有助于您的应用程序转换为轻松其他语言。再次，一个简单的例子如下所示：

Also, it would be good too to understand the use of strings.xml, as explained here. Basically, it is used to define constants that will not be hard-coded and you can call in your code. They help you to keep your code organized and also helps to translate your applications to other languages with ease. Again, a simple example is shown below:

<resources>

    <string name="OK">OK</string>
    <string name="cancel">Cancel</string>

    <!-- Validation error messages for EditText -->
    <string name="editText_validation_error_empty_field">The field cannot be empty.</string>
    <string name="editText_validation_error_numbers_only">Only numbers are allowed on this field.</string>
</resources>
