Android中 webView调用JS出错的解决办法

问题

    webview调用js出错。

    class testjs {
        ......
        public testjs(){
        }
       
        public void save(string data){           
            webview.loadurl("javascript: alert(" + data +")");
        }
        ......
    }

    w/webview(2088): java.lang.throwable: a webview method was called on thread 'javabridge'. all webview methods must be called on the same thread. (expected looper looper (main, tid 1) {b3dbcb18} called on looper (javabridge, tid 120) {b44a1af8}, fyi main looper is looper (main, tid 1) {b3dbcb18})

解决

将save方法修改为:

    public void save(string data){           
        webview.post(new runnable() {
            @override
            public void run() {
                webview.loadurl("javascript: alert(" + data +")");
            }
        });
    }

以上就是解决方法了，是不是很简单呢，希望小伙伴们能够喜欢。
