Convert String to integer - 

<pre><code>String waketime = String.valueOf(waketimeEnter.getText());
int number = Integer.parseInt(waketime);
//Do whatever you want with number
sleepNumber.setText(waketime);
</code></pre>

EDIT - 

Add this line to your EditText - 

<pre><code>android:inputType="number"
</code></pre>

So that the user can't enter a non-integral value. Then this will work perfectly.

blocks|key|4571537|text|由于您想要的是在EditText上，所以您必须解析它，下面是一个如何实现它的示例：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4571538|int+number+=+Integer.parseInt(waketimeEnter.getText().toString());|code-block|syntax|javascript|4571539|然后，由于您想把它作为一个带有text函数的setText()，它需要一个String，所以一个窍门是这样的：|4571540|sleepNumber.setText(String.valueOf(number));|4571541|entityMap^0|8|8|0|0|F|4|M|9|11|6|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|U|8|@$9|V|A|W|B|C]|$9|X|A|Y|B|C]|$9|Z|A|10|B|C]]|D|@]|E|$]]|$1|M|3|N|5|H|7|11|8|@]|D|@]|E|$I|J]]|$1|O|3|-4|5|6|7|12|8|@]|D|@]|E|$]]]|P|$]]

Since what you want it's on an <code>EditText</code> you'll have to parse it, here's an example to how to do it : 

<pre><code>int number = Integer.parseInt(waketimeEnter.getText().toString());
</code></pre>

Then since you want to put it as a <code>text</code> with <code>setText()</code> function it needs a <code>String</code> so a trick could be this : 

<pre><code>sleepNumber.setText(String.valueOf(number));
</code></pre>

blocks|key|4571559|text|尝试使用以下代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4571560|int+waketime+=+Integer.valueOf(waketimeEnter.getText().toString());

Try with following code:

<pre><code>int waketime = Integer.valueOf(waketimeEnter.getText().toString());
sleepNumber.setText(String.valueOf(waketime));
</code></pre>

I have a EditText that is set to number but am not sure how to get the value entered into the main.activity.java. Please help. I also want it to be a number integer not string so that I can perform operations with it. Thanks.

I know that this is how to do it for a string but not sure how to do it for an integer/number.

<pre><code> waketimeEnter = (EditText) findViewById(R.id.waketime_enter);

 public void buttonClick(View view) {

 String waketime = String.valueOf(waketimeEnter.getText());
 sleepNumber.setText(waketime);


}
</code></pre>
