使一个WebView中双击工作 [英] Make a Double Click work in a WebView

问题描述

我有一个有一定双击​​功能，因此与Android，当你双击在浏览器中它只是一个放大的网站。所以我建立一个web视图，所以我可以在骑双击并使其像它应该作出反应。

I have a Website that has some double click functionality and so with android when you double click in the browser it will just zoom. So I am building a WebView so I can over ride the double click and make it react like it should.

public class myWebView extends Activity{

GestureDetector gs = null;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    WebView engine = (WebView) findViewById(R.id.web_engine);
    engine.getSettings().setJavaScriptEnabled(true);
    engine.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
    engine.getSettings().setSupportMultipleWindows(true);
    engine.setWebChromeClient(new WebChromeClient() {
        @Override
        public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
                    return super.onJsAlert(view, url, message, result);
           }
    });
    engine.setWebViewClient(new WebViewClient() {
                @Override
                public boolean shouldOverrideUrlLoading(WebView view, String url) {
                    view.loadUrl(url);
                    return true;
                }
            });

    engine.setOnTouchListener(new View.OnTouchListener() {
        public boolean onTouch(View v, MotionEvent event) {
            if (gs == null) {
                gs = new GestureDetector(
                        new GestureDetector.SimpleOnGestureListener() {
                            //overrides the double click
                            @Override
                            public boolean onDoubleTapEvent(MotionEvent e) {
                                // SOME CODE THAT SIMULATES A DOUBLE CLICK
                                return true;
                            }
                        });
            }
            gs.onTouchEvent(event);
            return false;
        }
    }); 
    engine.loadUrl("http://www.google.com");
}
}

因此​​函数onDoubleTapEvent（MotionEvent五）将尽一切是在双击的事件之间。 以上code主要是由于太Cehm 。

所以在这一点上，我需要将其招执行双击。可我只是模拟点击的夫妇在那里？

So at this point I need to trick it to executing a a double click. Can I just simulate a Couple of click in there?

推荐答案

试试吧：

私人GestureDetector GS = NULL;

private GestureDetector gs = null;

私人OnTouchListener onTouch =新OnTouchListener（）{

private OnTouchListener onTouch = new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {

        if (gs == null) {
            gs = new GestureDetector(self,
                    new GestureDetector.SimpleOnGestureListener() {
                        @Override
                        public boolean onDoubleTapEvent(MotionEvent e) {

                            //Double Tap
                            snapWebView.zoomIn();//Zoom in
                            return true;
                        }

                        @Override
                        public boolean onSingleTapConfirmed(MotionEvent e) {

                            //Single Tab
                            snapWebView.zoomOut();// Zoom out
                            return false;
                        };
                    });
        }

        gs.onTouchEvent(event);

        return false;
    }
};

最后，设置OnTouch事件的WebView

Finally, set OnTouch event to WebView

webView.setOnTouchListener（onTouch）;

webView.setOnTouchListener(onTouch);
