java.lang.IllegalStateException:在除UI线程之外的另一个线程上调用View方法

Question

当我尝试使用Android 4.4(Kit kat)在我的nexus 4上打开webview时,我会收到以下错误消息:

Calling View methods on another thread than the UI thread.; 
java.lang.IllegalStateException: Calling View methods on another thread than the UI thread.
com.android.webview.chromium.WebViewChromium.createThreadException(WebViewChromium.java:268)

自从我更新到Android 4.4我的Nexus 4.

Answer 1

你的代码是什么样的？你可以试试

 runOnUiThread(new Runnable() {
        @Override
        public void run() {

            // TODO Your code
        }
    });

Answer 2

只需检查4.4 google的迁移网页视图,并在此处更改了一些内容

runOnUiThread(new Runnable() {
    @Override
    public void run() {
        // Code for WebView goes here
    }
});


// This code is BAD and will block the UI thread
webView.loadUrl("javascript:fn()");
while(result == null) {
  Thread.sleep(100);
}
