Android 中未调用 WebView 方法

我的 Web 视图没有调用 javascript 函数，它返回如下警告。任何人都可以建议如何消除以下警告。

07-30 10:15:44.031: W/webview_proxy(3770): java.lang.Throwable: Warning: A WebView method was called on thread 'WebViewCoreThread'. All WebView methods must be called on the UI thread. Future versions of WebView may not support use on other threads.

下面是我的功能。

public boolean onLongClick(View v){
    System.out.println("dfdsf");
    // Tell the javascript to handle this if not in selection mode
    //if(!this.isInSelectionMode()){
        this.getSettings().setJavaScriptEnabled(true);
        this.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
        this.getSettings().setPluginsEnabled(true);
        this.loadUrl("javascript:android.selection.longTouch();");
        mScrolling = true;
        //this.setJavaScriptEnabled(true);
    //}


    // Don't let the webview handle it
    return true;
}

正如警告所示，您正在调用 webview 方法WebViewCoreThread。 因此像这样修改你的代码，

public boolean onLongClick(View v){
    YourActivity.this.runOnUiThread(new Runnable() {
        public void run() {
            this.getSettings().setJavaScriptEnabled(true);
            this.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
            this.getSettings().setPluginsEnabled(true);
            this.loadUrl("javascript:android.selection.longTouch();");
            mScrolling = true;
        }
    });
}
