在方向變化時重新獲得當前活動狀態android

我有一個進度條，它從oncreate方法開始。當我改變屏幕方向爲橫向螺紋重啓和舊線的狀態已經一去不復返了請給我這個問題在方向變化時重新獲得當前活動狀態android

RelativeLayout layout; 
LayoutParams params; 
ProgressBar pb; 
int i; 
Bundle bundle; 
Thread t; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    // asyn name = new asyn(); 
    // name.execute(10); 
    bundle = savedInstanceState; 
    // params=RelativeLayout. 
    pb = (ProgressBar) findViewById(R.id.progressBar1); 
    pb.setMax(100); 
    t = new Thread(ProActivity.this); 
    t.start(); 
    Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)) 
      .getDefaultDisplay(); 
    int orientation = display.getOrientation(); 
    switch (orientation) { 
    case Configuration.ORIENTATION_PORTRAIT: 
     // 
     Toast.makeText(ProActivity.this, "portrait", 1000).show(); 
     // pb.setProgress(i); 
     setContentView(R.layout.landscape); 

     t = new Thread(ProActivity.this); 
     t.start(); 
     pb.setProgress(i); 

     break; 
    case Configuration.ORIENTATION_LANDSCAPE: 
     Toast.makeText(ProActivity.this, "Landscape", 1000).show(); 
     break; 
    } 
} 

@Override 
public void onConfigurationChanged(Configuration newConfig) { 

    super.onConfigurationChanged(newConfig); 
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) { 
     setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 

    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) { 
     setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 

    } 
} 

@Override 
public void onSaveInstanceState(Bundle savedInstanceState) { 
    super.onSaveInstanceState(savedInstanceState); 
    savedInstanceState = bundle; 
} 

public void run() { 

    for (i = 0; i < 100; i++) { 

     pb.setProgress(i); 
     try { 
      Thread.sleep(1000); 
     } catch (InterruptedException e) { 

      e.printStackTrace(); 
     } 

    } 
}

我嘗試了這些方法的任何方法或建議，但它不能恢復活動線程狀態
