|

<p>The <code>addListener</code> function connects a JavaScript function to an identified native keyboard notification event.</p>
|
||
<p>This function then returns the reference to the listener.</p>
|
||
<p>@param {string} eventName The <code>nativeEvent</code> is the string that identifies the event you're listening for. This can be any of the following:</p>
|
||
<ul>
|
||
<li><code>keyboardWillShow</code></li>
|
||
<li><code>keyboardDidShow</code></li>
|
||
<li><code>keyboardWillHide</code></li>
|
||
<li><code>keyboardDidHide</code></li>
|
||
<li><code>keyboardWillChangeFrame</code></li>
|
||
<li><code>keyboardDidChangeFrame</code></li>
|
||
</ul>
|
||
<p>Note that if you set <code>android:windowSoftInputMode</code> to <code>adjustResize</code>, only <code>keyboardDidShow</code> and <code>keyboardDidHide</code> events will be available on Android. If you set <code>android:windowSoftInputMode</code> to <code>adjustNothing</code>, no events will be available on Android. <code>keyboardWillShow</code> as well as <code>keyboardWillHide</code> are generally not available on Android since there is no native corresponding event.</p>
|
||
<p>@param {function} callback function to be called when the event fires.</p>
