我如何将字符串转换成整数?

How do I convert a string into an integer?

我有一个文本框,我让用户输入一个数字:

I have a textbox I have the user enter a number into:

EditText et = (EditText) findViewById(R.id.entry1);
String hello = et.getText().toString();

和值分配给字符串你好

我想将其转换为整数,这样我就可以得到他们所输入的号码;它将用于以后的code。

I want to convert it to a integer so I can get the number they typed; it will be used later on in code.

有没有办法让的EditText 来一个整数?这将跳过中间人。如果没有,字符串整数会就好了。

Is there a way to get the EditText to a integer? That would skip the middle man. If not, string to integer will be just fine.

推荐答案

请参阅Integer类和静态parseInt()函数的方法:

See the Integer class and the static parseInt() method:

http://developer.android.com/reference/java/lang/Integer.html

Integer.parseInt(et.getText().toString());

您将需要捕捉,虽然NumberFormatException的问题的情况下,同时解析,因此:

You will need to catch NumberFormatException though in case of problems whilst parsing, so:

int myNum = 0;

try {
    myNum = Integer.parseInt(et.getText().toString());
} catch(NumberFormatException nfe) {
   System.out.println("Could not parse " + nfe);
}
