Asynchtask用濺射屏幕

我想與我的申請asynchtask第一顯示啓動畫面之間murge，我開始與飛濺5 Seconde系列，然後asynchtask，我想，當我也開始我的飛濺asynchtask開始加載，這是我的濺代碼：Asynchtask用濺射屏幕

public class SplashActivity extends Activity { 

    private static String Spsc = SplashActivity.class.getName(); 
    private static long time = 5; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
     this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); // Removes notification bar 
     setContentView(R.layout.splash); 
     IntentLauncher launcher = new IntentLauncher(); 
     launcher.start(); 
    } 
    private class IntentLauncher extends Thread { 
     @Override 
     public void run() { 
      try { 
       Thread.sleep(time*1000); 
      } catch (Exception e) { 
       Log.e(Spsc, e.getMessage()); 
      } 
      Intent intent = new Intent(SplashActivity.this, MainActivity.class); 
      SplashActivity.this.startActivity(intent); 
      SplashActivity.this.finish(); 
     } 
    } 
}

，這是從mainActivity我飛濺：

class FetchPosts extends AsyncTask<Void, Void, Void> { 
     private ProgressDialog progressDialog; 
     @Override 
     protected void onPreExecute() {   
      super.onPreExecute(); 
      progressDialog = ProgressDialog.show(MainActivity.this, "", getString(R.string.loading_message)); 
     } 

     @Override 
     protected Void doInBackground(Void... params) { 
      articles = Services.getPosts(MainActivity.this); 

      return null; 
     } 

     @Override 
     protected void onPostExecute(Void result) { 
      super.onPostExecute(result); 

      progressDialog.dismiss(); 

     } 
    }

你的問題是什麼？什麼是/不工作？ – codeMagic 2013-05-06 16:48:23

這是2項活動，我想在它們之間發起飛濺，並在同一時間asynchtask加載數據。 – Sherlock 2013-05-06 17:11:12

我明白了。我問的是發生什麼事/現在不在運行時發生？我們知道你想要什麼。我們不知道的是沒有用到的東西。此外，可能需要把你的'AsyncTask'作爲一個內部類的'MainActivity'的，如果它是不是已經或至少'MainActivity' – codeMagic 2013-05-06 17:13:16

只需

public class SplashActivity extends Activity { 

private static String Spsc = SplashActivity.class.getName(); 
private static long time = 5; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); // Removes notification bar 
    setContentView(R.layout.splash); 
    IntentLauncher launcher = new IntentLauncher(); 
    launcher.start(); 
} 
private class IntentLauncher extends Thread { 
    @Override 
    public void run() { 
     try { 
      Thread.sleep(time*1000); 
     } catch (Exception e) { 
      Log.e(Spsc, e.getMessage()); 
     } 
     //Intent intent = new Intent(SplashActivity.this, MainActivity.class); 
     //SplashActivity.this.startActivity(intent); 
     //SplashActivity.this.finish(); 
      new FetchPosts().execute(); 
    } 
    } 
public class FetchPosts extends AsyncTask<Void, Void, Void> { 
    private ProgressDialog progressDialog; 
    @Override 
    protected void onPreExecute() {   
     super.onPreExecute(); 
     progressDialog = ProgressDialog.show(MainActivity.this, "", getString(R.string.loading_message)); 
    } 

    @Override 
    protected Void doInBackground(Void... params) { 
     articles = Services.getPosts(MainActivity.this); 

     return null; 
    } 

    @Override 
    protected void onPostExecute(Void result) { 
     super.onPostExecute(result); 

     progressDialog.dismiss(); 

    } 
} 
}

我應該使用類的東西mainActivity還是什麼？這是兩個活動之間的詭計？ – Sherlock 2013-05-06 16:57:34

如果要調用'MainActivity.java'爲只執行'AsyncTask'比現在你不東東該類事業'新FetchPosts（）執行（）;'這將'AsyncTask' – 2013-05-06 17:02:10

好的謝謝你，我會嘗試用這 – Sherlock 2013-05-06 17:11:31

嘗試下面的代碼，它會啓動splashscreen acctivity時啓動asynctask

public class SplashActivity extends Activity { 

private static String Spsc = SplashActivity.class.getName(); 
private static long time = 5; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); // Removes notification bar 
    setContentView(R.layout.splash); 
    FetchPosts obj=new FetchPosts(); 
    obj.execute("dummystring"); 
} 
} 

class FetchPosts extends AsyncTask<String, Void, String> { 
    private ProgressDialog progressDialog; 
    @Override 
    protected void onPreExecute() {   
     super.onPreExecute(); 
     progressDialog = ProgressDialog.show(MainActivity.this, "", getString(R.string.loading_message)); 
    } 

    @Override 
    protected Void doInBackground(String... params) { 
     articles = Services.getPosts(MainActivity.this); 

     return null; 
    } 

    @Override 
    protected void onPostExecute(Void result) { 
     super.onPostExecute(result); 

     progressDialog.dismiss(); 

    } 
}

當我添加的活動該類使其許多錯誤 – Sherlock 2013-05-06 17:13:13

@Kira什麼錯誤？ – sam 2013-05-06 17:17:01

@Kira在AsyncTask <>之後用String替換第一個和第三個void並且還使doInBackground（String ... params）的參數 – sam 2013-05-06 17:21:55
