如何从EditText返回int ?(安卓)

Basically, I want an EditText in Android where I can have an integer value entered into. Perhaps there is a more appropriate object than EditText for this?

基本上，我想要一个EditText在Android中，我可以输入一个整数值。也许还有比EditText更合适的对象?

For now, use an EditText. Use android:inputType="number" to force it to be numeric. Convert the resulting string into an integer (e.g., Integer.parseInt(myEditText.getText().toString())).

现在，使用EditText。使用android:inputType="number"来强制它为数值。将结果字符串转换为整数(例如，Integer.parseInt(myEditText.getText(). tostring()))))。

In the future, you might consider a NumberPicker widget, once that becomes available (slated to be in Honeycomb).

将来，您可能会考虑一个NumberPicker小部件，一旦它可用(预定在蜂巢中)。

Set the digits attribute to true, which will cause it to only allow number inputs.

将digit属性设置为true，这将导致它只允许数字输入。

Then do Integer.valueOf(editText.getText()) to get an int value out.

然后执行Integer.valueOf(editText.getText())来获取一个int值。

First of all get a string from an EDITTEXT and then convert this string into integer like

首先从EDITTEXT获取一个字符串，然后将该字符串转换为整数

      String no=myTxt.getText().toString();       //this will get a string                               
      int no2=Integer.parseInt(no);              //this will get a no from the string

You can do this in 2 ways:

你可以用两种方法:

1: Change the input type(In your EditText field) in the layout file to android:inputType="number"

1:将布局文件中的输入类型(在EditText字段中)更改为android:inputType=“number”

或

2: Use int a = Integer.parseInt(yourEditTextObject.getText().toString());

2:使用int a = Integer.parseInt(yourEditTextObject.getText().toString());
