WebView loadDataWithbaseURL java.lang.NullPointerException

Question

//. . . 

public class MainActivity extends Activity { 

    //. . . 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     //. . . 
     mainActivityProcedure (); 
    } 

    //. . . 

    public static void mainActivityProcedure () { 
     //. . . 
     AnotherActivity.anotherActivityProcedure () ; 
     SomeActivity.someActivityProcedure (); 
     //. . . 
    } 

    //. . . 

} 

//. . . 

public class SomeActivity extends Activity { 

    //. . . 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     //. . . 
     someWebView = (WebView) findViewById (R.id.someWebView); 
     //. . . 
    } 

    //. . . 

    public static void someActivityProcedure () { 
     //. . . 
     try { 
      someWebView.loadDataWithBaseURL (null , someHTMLCode, mimeType, encoding, null); 
    catch (Exception e) { 
     Log.i("SomeActivity", "someWebView loadDataBaseURL() " + e.toString()); 
    } 
     //. . . 
    } 

    //. . . 
} 

//. . . 

public class AnotherActivity extends Activity { 

    //. . . 

    @Override 
    protected void onCreate (Bundle savedInstanceState) { 
     //. . . 
     anotherWebView = (WebView) findViewById (R . id.anotherWebView) ; 
     //. . . 
    } 

    //. . . 

    public static void anotherActivityProcedure () { 
     //. . . 
     anotherWebView . loadDataWithBaseURL (null, anotherHTMLCode, mimeType, encoding, null) ; 
     //. . . 
    } 
} 

AnotherActivityProcedure調用時，AnotherActivity總是加載另一個HTLCode。 SomeActivity負載someHTMLCode除非mainActivityProcedure從MainActivity.onCreate調用。 出了什麼問題someWebView或SomeActivity？ 我不能在這裏把原來的代碼。

增加：Replacin`空在loadDataWithBaseURL（）不解決它。 增加：logcat的顯示，提出Log.i（）從捕獲的消息顯示java.lang.NullPointerException。

試試這個，Initilized SomeActivity內MainActivity和使用_someactivity對象，你可以訪問。

SomeActivity _someactivity = new SomeActivity(); 
_someactivity.someActivityProcedure();
