WebView介绍

[英]Shortcut taken : the webview doesn't extends directly View. http://developer.android.com/reference/android/webkit/WebView.html
[中]采取的快捷方式：webview不直接扩展视图。http://developer.android.com/reference/android/webkit/WebView.html

代码示例

webView.setOnTouchListener(this);
client = new WebViewClient(){ 
  @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { 
    handler.sendEmptyMessage(CLICK_ON_URL);
webView.setWebViewClient(client);
webView.setVerticalScrollBarEnabled(false);
webView.loadUrl("http://www.example.com");
if (v.getId() == R.id.web && event.getAction() == MotionEvent.ACTION_DOWN){
  handler.sendEmptyMessageDelayed(CLICK_ON_WEBVIEW, 500);
