如何在Web視圖中捕獲電話號碼android

Question

我創建了一個JSON解析器來捕獲數據並顯示在列表視圖中。然後我在webview中打開一個url。現在我想在該webview中捕獲電話號碼以撥打電話。那麼我怎樣才能在該webview中捕獲電話號碼？

Answer 1

使用evaluateJavascript，嘗試：

String getNumber = ""; 
getNumber = "var np = document.getElementById('postingbody'), t;"+ 
     "if(np && np.innerHTML){"+ 
     " t = String(np.innerHTML).match(/(\\d{3})\\-(\\d{3})\\-(\\d{4})/g);"+ 
     " if(t && t.length>0){"+ 
     "  return t[0];"+//show first number found 
     " } else {"+ 
     "  return 1;"+//return integer (custom error 1) 
     " }"+ 
     "} else {"+ 
     " return 2;"+//return integer (custom error 2) 
     "}"; 

webView.evaluateJavascript(getNumber, new ValueCallback<String>() { 
    @Override 
    public void onReceiveValue(String s) { 
     Log.d("LogName", s); 
    } 
    @Override 
    public void onReceiveValue(int s) { 
     if(s==1){//custom error 1 
      Log.d("LogName", "phone number not found"); 
     } else if(s==2){//custom error 2 
      Log.d("LogName", "#postingbody (DOM element) not found"); 
     } 
    } 
});
