android 浏览器开技术

1.网页内的右键菜单

 public boolean onLongClick(View view) {
         // 获取点击的元素
         HitTestResult mResult = mWebView.getHitTestResult();

         final int type = mResult.getType();
         switch (type) {
             case HitTestResult.ANCHOR_TYPE:
             case HitTestResult.SRC_ANCHOR_TYPE:
                 //点击的是链接
                 break;

             case HitTestResult.IMAGE_TYPE:
             case HitTestResult.IMAGE_ANCHOR_TYPE:
             case HitTestResult.SRC_IMAGE_ANCHOR_TYPE:
                 //点击的是图片
                 break;

             default:
                 //点击的是空白处
                 break;
         }
         return true;
     }

根据是图片还是链接还是空白做判断

2.网页内的自由复制

 /**
      * 网页里 复制粘贴
      * @param view webView
      * @author ethan
      */
     private void emulateShiftHeld(KeyEvent.Callback view)
     {
         try
         {
             KeyEvent shiftPressEvent = new KeyEvent(0, 0, KeyEvent.ACTION_DOWN,
                     KeyEvent.KEYCODE_SHIFT_LEFT, 0, 0);
             shiftPressEvent.dispatch(view);
         } catch (Exception e)
         {
         }
     }

3.出错界面

webkit自带的出错界面不够霸气,于是改为自己做的出错界面

 new WebViewClient()
 ...此为背景
 @Override
         public void onReceivedError(WebView view, int errorCode,
                 String description, String failingUrl) {
             view.stopLoading();
             view.clearView();

             // 显示出错界面
             mWebView.loadUrl("file:///android_asset/error.html");
         }

4.点外部链接调用自己的浏览器

在manifest.xml里主activity加入intent

 <p style="color: rgb(51, 51, 51); font-family: Arial; font-size: 16px; line-height: 25px; text-align: left; "><!-- For these schemes were not particular MIME type has been
                  supplied, we are a good candidate. -->
             <intent-filter>
                 <action android:name="android.intent.action.VIEW" />
                 <category android:name="android.intent.category.DEFAULT" />
                 <category android:name="android.intent.category.BROWSABLE" />
                 <data android:scheme="http" />
                 <data android:scheme="https" />
                 <data android:scheme="about" />
                 <data android:scheme="javascript" />
             </intent-filter>
             <!--  For these schemes where any of these particular MIME types
                   have been supplied, we are a good candidate. -->
             <intent-filter>
                 <action android:name="android.intent.action.VIEW" />
                 <category android:name="android.intent.category.BROWSABLE" />
                 <category android:name="android.intent.category.DEFAULT" />
                 <data android:scheme="http" />
                 <data android:scheme="https" />
                 <data android:scheme="inline" />
                 <data android:mimeType="text/html"/>
                 <data android:mimeType="text/plain"/>
                 <data android:mimeType="application/xhtml+xml"/>
                 <data android:mimeType="application/vnd.wap.xhtml+xml"/>
             </intent-filter>
                 <action android:name="android.intent.action.VIEW" />
                 <category android:name="android.intent.category.DEFAULT" />
                 <category android:name="android.intent.category.BROWSABLE" />
                 <data android:scheme="file" />
             </intent-filter></p>

外部调用就ok了,连file文件都能调用,若自己调用的话
