Retrieving data from EditText in Android?

问题:

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????

回答1:

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.

This should work:

EditText edit = (EditText) findViewById(R.id.editTextID);
Editable editable = edit.getText();
String allTheText = editable.toString();

Replace editTextID with the ID for your EditText.

use this code for get data from Edit text

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

回答4:

You can use this code also:

EditText edit = (EditText) findViewById(R.id.editTextID);

String string_object=String.valueOf(edit.getText());
