添加setOnTouchListener后，Webview不会滚动(Webview not scrolling after adding setOnTouchListener)

我有一个webview与下面的代码：

WebSettings webSettings = webView.getSettings(); webSettings.setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN); webSettings.setSavePassword(false); webSettings.setSaveFormData(false); webSettings.setSupportZoom(false); webView.setBackgroundColor(0); webView.loadDataWithBaseURL(null, text, "text/html", "UTF-8", null); webView.setOnTouchListener(onTouchListener); webView.setVerticalScrollBarEnabled(true);

如果我评论webView.setOnTouchListener(onTouchListener); 这个webview会滚动，但如果我添加它，那么webview将不会滚动任何原因，为什么呢？

我的倾听者

OnTouchListener onTouchListener = new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { int action = event.getAction(); if (action == MotionEvent.ACTION_UP) { //do something } return false; } };

i have a webview with the below code:

WebSettings webSettings = webView.getSettings(); webSettings.setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN); webSettings.setSavePassword(false); webSettings.setSaveFormData(false); webSettings.setSupportZoom(false); webView.setBackgroundColor(0); webView.loadDataWithBaseURL(null, text, "text/html", "UTF-8", null); webView.setOnTouchListener(onTouchListener); webView.setVerticalScrollBarEnabled(true);

If i comment webView.setOnTouchListener(onTouchListener); this then webview will scroll but if i add it then the webview will not scroll any reason why so?

EDIT

My Listener

OnTouchListener onTouchListener = new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { int action = event.getAction(); if (action == MotionEvent.ACTION_UP) { //do something } return false; } };

最满意答案

你的onTouchListener变量是否引用了一个总是返回true ？来自http://developer.android.com/reference/android/view/View.OnTouchListener.html上的文档返回如果侦听器已消耗该事件，则为true，否则为false。

确保返回false 。

Your onTouchListener variable is referencing an implementation that always returns true? From the documentation at http://developer.android.com/reference/android/view/View.OnTouchListener.html Returns True if the listener has consumed the event, false otherwise.

Make sure to return false.
