Did you try this?

<pre><code>myButton.setEnabled(false); 
</code></pre>

Update: Thanks to Gwen. Almost forgot that <code>android:clickable</code> can be set in your XML layout to determine whether a button can be clickable or not.

blocks|key|1466615|text|您不能在您的XML中启用或禁用它(因为您的布局是在运行时设置的)，但是您可以在使用android:clickable启动活动时设置它是否可单击。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1466616|entityMap|0|LINK|mutability|MUTABLE|url|http://developer.android.com/reference/android/view/View.html#attr_android:clickable^0|15|H|15|H|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@$9|O|A|P|B|C]]|D|@$9|Q|A|R|1|S]]|E|$]]|$1|F|3|-4|5|6|7|T|8|@]|D|@]|E|$]]]|G|$H|$5|I|J|K|E|$L|M]]]]

You can't enable it or disable it in your XML (since your layout is set at runtime), but you can set if it's clickable at the launch of the activity with <a href="http://developer.android.com/reference/android/view/View.html#attr_android:clickable" rel="noreferrer"><code>android:clickable</code></a>.

blocks|key|2298336|text|您只需在您的活动中编写一行代码|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2298337|Button+btn+=+(Button)+findViewById(R.id.button1);

You just write a single line of code in your activity

<pre><code>Button btn = (Button) findViewById(R.id.button1);
btn.setEnabled(false);
</code></pre>

When you want to enable the same button just write

<pre><code>Button btn = (Button) findViewById(R.id.button1);
btn.setEnabled(true);
</code></pre>

blocks|key|230599|text|在我的情况下，|type|unstyled|depth|inlineStyleRanges|entityRanges|data|230600|myButton.setEnabled(false);

In my case, 

<pre><code>myButton.setEnabled(false);
myButton.setEnabled(true);
</code></pre>

is working fine and it is enabling and disabling the button as it should. But once the button state becomes disabled, it never goes back to the enabled state again, although it's clickable. I tried invalidating and refreshing the drawable state, but no luck.

<pre><code>myButton.invalidate();
myButton.refreshDrawableState();
</code></pre>

If you or anyone having a similar issue, what works for me is setting the background drawable again. Works on any API Level.

<pre><code>myButton.setEnabled(true);
myButton.setBackgroundDrawable(activity.getResources().getDrawable(R.drawable.myButtonDrawable));
</code></pre>

In Java, once you have the reference of the button:

<pre><code>Button button = (Button) findviewById(R.id.button);
</code></pre>

To enable/disable the button, you can use either:

<pre><code>button.setEnabled(false);
button.setEnabled(true);
</code></pre>

Or:

<pre><code>button.setClickable(false);
button.setClickable(true);
</code></pre>

Since you want to disable the button from the beginning, you can use button.setEnabled(false); in the onCreate method.
Otherwise, from XML, you can directly use:

<pre><code>android:clickable = "false"
</code></pre>

So:

<pre><code>&lt;Button
 android:id="@+id/button"
 android:layout_height="wrap_content"
 android:layout_width="wrap_content"
 android:text="@string/button_text"
 android:clickable = "false" /&gt;
</code></pre>

blocks|key|1466678|text|首先，在xml中，将按钮设置为android:clickable="false"|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1466679|<Button

first in xml make the button as <code>android:clickable="false"</code>

<pre><code>&lt;Button
 android:id="@+id/btn_send"
 android:clickable="false"/&gt;
</code></pre>

then in your code, inside <code>oncreate()</code> method set the button property as

<pre><code>btn.setClickable(true);
</code></pre>

then inside the button click change the code into 

<pre><code>btn.setClickable(false);

@Override
protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 btnSend = (Button) findViewById(R.id.btn_send);
 btnSend.setClickable(true);
 btnSend.setOnClickListener(new OnClickListener() {

 @Override
 public void onClick(View v) {
 btnSend.setClickable(false);

 }
 });
}
</code></pre>

blocks|key|2298484|text|是的，可以在XML中禁用它，只需使用以下命令：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2298485|<Button

EDIT: 
In reply to @jeroen-bollen

<blockquote>
<pre><code> View.OnClickListener 
</code></pre>
 
 is Interface definition for a callback to be invoked when a view is clicked.
 
 with method definition 

<pre><code>void onClick(View v);
</code></pre>
</blockquote>

when the view is clicked the View class object makes callback to method onClick() sending as parameter itself, so null view parameter should not occur if it does it's an Assertion Error it could happen for example when View object class was destroyed in meanwhile (for example collected by GC) or method was tampered due to hack 

little about instanceof &amp; null 

<blockquote>
 JLS / 15.20.2. Type Comparison Operator instanceof
 
 At run time, the result of the instanceof operator is true
 if the value of the RelationalExpression is not null
 and the reference could be cast to the ReferenceType

 Otherwise the result is false.

<hr>

three words from the Author

IF U ASK WHY ? 

MOSTLY TO AVOID NullPointerException 

Little more code will save your time on later bug tracking in your code &amp; reduces the occurrence of abnomalies. 

consider following example:

<pre><code>View.OnClickListener listener = new OnClickListener() {

 @Override
 public void onClick(View v) {
 btnSend.setClickable(false);

 }
});

btnSend.setOnClickListener(listener)
btnCancel.setOnClickListener(listener)

You can disable a button from your xml but that won't be dynamic. Best way to disable button dynamically is.
<pre><code>myButton.setEnabled(false);
</code></pre>

I have created a layout that contains two buttons, Next and Previous. In between the buttons I'm generating some dynamic views. So when I first launch the application I want to disable the "Previous" button since there wont be any previous views. I also want to disable the "Next" button when there are not more views to display. Is there anyway to disable the buttons?

我已经创建了一个包含两个按钮的布局，下一个和上一个按钮。在按钮之间，我生成了一些动态视图。因此，当我第一次启动应用程序时，我想禁用“上一步”按钮，因为没有任何以前的视图。当没有更多的视图可显示时，我还想禁用“下一步”按钮。有什么办法可以禁用这些按钮吗？​​
