將Webview開始網址添加到webview的sharedpreference

我仍在學習Java。我試圖讓SharedPreferences在我的WebView中設置url，以便我可以設置下次啓動應用程序時顯示的頁面。並嘗試使用菜單設置/更改值。將Webview開始網址添加到webview的sharedpreference

這是我到目前爲止有：

public class test extends Activity { 

public static final String PREFS_NAME = "SharedPreferences"; 

public static final String PREF_STRING = "http://www.google.com"; 
private SharedPreferences mPrefs; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    mPrefs = getSharedPreferences(PREFS_NAME, 0); 
    webview = new WebView(this) { 

    }; 
    webChromeClient = new WebChromeClient() { 

    }; 

    webview.setWebChromeClient(webChromeClient); 
    webview.setWebViewClient(webViewClient); 
    setContentView(webview); 

    /** Load the Browser Settings */ 
    webview.loadUrl(PREF_STRING); 

    SharedPreferences settings = getSharedPreferences("StartPage", 0); 
    settings.getString("PREF_STRING", "http://www.google.com"); 

} 

/** Begin Globals */ 
public WebView webview; 
public WebChromeClient webChromeClient; 
public WebViewClient webViewClient; 

/*** define menu options */ 
private static final int MENU_PAGE1 = 1; 
private static final int MENU_PAGE2 = 2; 

/*** menu items */ 
public boolean onCreateOptionsMenu(Menu menu) { 
    menu.add(0, MENU_PAGE1, 0, "Set page 1 to show when app is started"); 
    menu.add(0, MENU_PAGE2, 0, "Set page 2 to show when app is started"); 

    return true; 
} 

public boolean onOptionsItemSelected(MenuItem item) { 
    switch (item.getItemId()) { 
    case MENU_PAGE1: 
     Editor e = mPrefs.edit(); 
     e.putString(PREF_STRING, "http://www.yahoo.com"); 
     e.commit(); 

     Toast.makeText(this, "Page 1 is set!", Toast.LENGTH_SHORT).show(); 

     return true; 
    } 
    switch (item.getItemId()) { 
    case MENU_PAGE2: 
     Editor e = mPrefs.edit(); 
     e.putString(PREF_STRING, "http://www.ask.com"); 
     e.commit(); 

     Toast.makeText(this, "Page 2 is set!", Toast.LENGTH_SHORT).show(); 

     return true; 

    } 

    return false; 

} 
}

如此接近的是，到目前爲止...任何提示或想法？

你想從sharepref獲取網址並在webview中打開？ – 2011-06-04 05:54:03

@CapDroid種類，我想它將我的選擇存儲在菜單中，然後顯示我重新啓動手機和應用程序後選擇的頁面。 – Colby 2011-06-04 06:09:43

Try this: 

@Override 
public void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 

    mPrefs = getSharedPreferences(PREFS_NAME, 0); 
    webview = new WebView(this) { 

    }; 
    webChromeClient = new WebChromeClient() { 

    }; 

    webview.setWebChromeClient(webChromeClient); 
    webview.setWebViewClient(webViewClient); 
    setContentView(webview); 

    /* Load the last saved preference. */ 
    webview.loadUrl(mPrefs.getString(PREF_STRING, "http://www.google.com")); 

}

「webview.loadUrl（mPrefs.getString（PREF_STRING，」http://www.google.com「））;」是嗎，謝謝！ – Colby 2011-06-04 06:16:59
