Webview每當活動聚焦時加載相同的url

我在我的應用中有Webview。當我打開我的應用程序並切換到另一個應用程序或只是進入主屏幕，然後重新打開我的應用程序。 Webview加載我設置的網址以加載onCreate()方法，而不是我在關閉應用程序之前訪問的網址。Webview每當活動聚焦時加載相同的url

我保存的網址使用此方法sharedprefrences的幫助： http://developer.android.com/training/basics/data-storage/shared-preferences.html

標準savedUrl是它加載在第一onCreate()方法標準的URL，但它讓我寫的值還有應用程序暫停時重置？

某些日誌：

保存的網址：

      if (fromLogin) {

       mWebView.loadUrl("javascript:var x = document.getElementById('modlgn-username').value = '" + userName + "';"); 
       mWebView.loadUrl("javascript:var z = document.getElementById('modlgn-passwd').value = '" + passWord + "';"); 
      /*mWebView.loadUrl("javascript:(function(){"+ 
        "l=document.getElementById('form-login-submit');"+ 
        "e=document.createEvent('HTMLEvents');"+ 
        "e.initEvent('click',true,true);"+ 
        "l.dispatchEvent(e);"+ 
        "})()");*/ 
       //var y = $document.getElementById('form-login-submit').click();"); 
       //mWebView.loadUrl("http://www.google.com/"); 
       mWebView.loadUrl("javascript: var y = document.getElementById('form-login-submit'); y.click();"); 
      } 
      if (mWebView.getUrl() != null) { 
       SharedPreferences sharedpref = Web.this.getPreferences(Context.MODE_PRIVATE); 
       SharedPreferences.Editor editor = sharedpref.edit(); 
       String temp = mWebView.getUrl(); 
       Log.d("SAVING_URL", temp); 
       editor.putString(getString(R.string.loaded_url), mWebView.getUrl()); 
       editor.commit(); 
      }

載入URL中onCreate()

Log.d("LOADING_URL", getResources().getString(R.string.loaded_url)); 
mWebView.loadUrl(getResources().getString((R.string.loaded_url)));

你能發佈您的代碼？ – nurisezgin

我已添加代碼 –

您可以控制提交結果嗎？簡單地說，布爾isCommited = editor.commit（） – nurisezgin

你不應該使用editor.getString(R.string.loaded_url, "")如果您正在使用共享的偏好，而不只是getResources().getString((R.string.loaded_url))？

編輯
不editor.getString(R.string.loaded_url, "")
但 sharedpref.getString(R.string.loaded_url, "")
我的壞

編輯器沒有'getString（）'方法。 –

對不起，我的意思是''sharedPreference.getString（）' –

'getString（）'方法需要一個'String'而不是'int'像R.string.loaded_url。 –
