关于Android WebView的那点事儿..

1.禁止网页长按弹出文字选择功能：

mWebView.setOnLongClickListener(new WebView.OnLongClickListener() {@Overridepublic boolean onLongClick(View v) {// TODO Auto-generated method stubreturn true;}});

2.只有点击请求的是链接是才会调用，重写此方法返回true表明点击网页里面的链接还是在当前的webview里跳转，不跳到浏览器那边。（可重写此方法在跳转网页时修改其标题）：

@Overridepublic boolean shouldOverrideUrlLoading(WebView view, String url) {    //设置页面新标题String title = getTitle(url);mTitleText.setText(title);    //加载页面view.loadUrl(url);return true;}

3.在网页中处理按键事件：

@Overridepublic boolean shouldOverrideKeyEvent(WebView view, KeyEvent event) {        return super.shouldOverrideKeyEvent(view, event);}

4.点击网页中电话号码或者手机进行拨打电话：

@Overridepublic boolean shouldOverrideUrlLoading(WebView view, String url) {    if(url.contains("tel:")) {String phone = url.substring(url.indexOf(":") + 1);SystemUtil.callPhone(WebViewActivity.this, phone);return true;}return true;}/** * 拨打电话 * @param context * @param num */public static void callPhone(Context context, String num) {    if(isPhoneNumberValid(num)) {        //点击数字后立即拨打//Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + num));//点击数字后跳转到拨号盘Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("tel:" + num));context.startActivity(intent);}}/** * 验证电话号码或者手机号码 * @param phoneNumber * @return */public static boolean isPhoneNumberValid(String phoneNumber) {boolean isValid = false;String expression = "((^(13|15|18)[0-9]{9}$)|(^0[1,2]{1}\\d{1}-?\\d{8}$)|"+ "(^0[3-9] {1}\\d{2}-?\\d{7,8}$)|(^0[1,2]{1}\\d{1}-?\\d{8}-(\\d{1,4})$)|"+ "(^0[3-9]{1}\\d{2}-? \\d{7,8}-(\\d{1,4})$))";CharSequence inputStr = phoneNumber;Pattern pattern = Pattern.compile(expression);Matcher matcher = pattern.matcher(inputStr);if(matcher.matches()) {isValid = true;}return isValid;}
