从Android中的EditText检索数据? [英] Retrieving data from EditText in Android?

问题描述

如何用Java处理用户输入EditText的内容?仅举一个例子，也许用户输入我这个周末过得很愉快！"到EditText中(例如Facebook更新或Tweet).我想做些什么，我这个周末过得很愉快！"那么如何在应用程序中使用Java来影响它呢??

解决方案

您可以使用

EditText editText = (EditText) findViewById(R.id.editText1);
String value = editText.getText().toString();

从EditText取回值

EditText editText = (EditText) findViewById(R.id.editText1);
String value = editText.getText().toString();

我建议.trim()使用此值，因为您可能不希望尾随空格的用户倾向于离开.

您应该使用Button onClick事件来调用上述方法，因为它或多或少是您要查找的UX.

How do I work with whatever the user enters into an EditText, in Java? For just one example, maybe the user enters "I had a great time this weekend!" into an EditText (like a Facebook update or Tweet). I want to do something with "I had a great time this weekend!" so how do I use Java to affect it in the app????

解决方案

You can get a value back from an EditText with

EditText editText = (EditText) findViewById(R.id.editText1);
String value = editText.getText().toString();

I recommend .trim()'ing this value, since you probably don't want the trailing whitespace users tend to leave.

You should use a Button onClick event to call the above methods, because it's more or less likely to be the UX you are looking for.
