Android的搜索條進度不更新

我使用搜索欄對我的應用程序的Soundpool音量控制，我用PopupWindow的搜索條，一切工作正常，除了，每當我更改或暫停我的活動，我再次打開搜索條popupwindow，搜索條無我上次保存的價值越長。但它總是返回到它的默認值100％，甚至我用SharedPreferences什麼效果很好，但只有當我不離開當前活動。Android的搜索條進度不更新

將這個的onResume（）

 int value = 0; 
    SharedPreferences prefs = getBaseContext().getSharedPreferences("mySharedPrefsFilename1", Context.MODE_PRIVATE); 
    value = prefs.getInt("seekBarValue", 100) 
    volbar1.setProgress(value);

嗨，我嘗試，但它使我的應用程序崩潰..必須測試更多的，也許是我做錯了什麼.. – Blackstarguy

volbar1很可能無法初始化爲此volbar1 =（搜索欄）popupView.findViewById（R.id .VolB） –

這就奇怪了，其實，搜索欄的作品，因爲它應該但從設備返回音量總是默認爲100％，如果我暫停或更改活動.. – Blackstarguy

我做同樣的事情。它爲我工作。這是我的代碼。它沒有所有的聲音的東西。
