Asynchtask用溅射屏幕

Question

我想与我的申请asynchtask第一显示启动画面之间murge，我开始与飞溅5 Seconde系列，然后asynchtask，我想，当我也开始我的飞溅asynchtask开始加载，这是我的溅代码：

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(); 
     } 
    } 
} 

，这是从mainActivity我飞溅：

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(); 

     } 
    }

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(); 

    } 
} 
}

尝试下面的代码，它会启动splashscreen acctivity时启动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(); 

    } 
}
