onkeypress 事件未在 Android Webview 4.4 中触发

Question

OnKeyPress is not being called in android webview... My Html code is simple

<input type="number" onkeypress="myFunc()"/>

function myFunc(){
alert(fired up!);
}

All the other keyevents ie keyup, keydown are working.

Answer 1

• Try to use WebChromeClient for loading it.
  
• Try to build with lower version. Because in latest version API 17 and above they added JavascriptInterface . You need to include this as a seperate class that extends JavascriptInterface.
  
  To reduce application compatibility try to build with 16 or below.

Answer 2

Android Webview really doesn't fire onkeypress event (even on newer versions of Android).

One posible solution is to replace it with onkeyup or onkeydown , like this:

<input type="number" onkeyup="myFunc()"/>

function myFunc(){
   alert(fired up!);
}
