如何在Andengine Live Wallpaper服務中使用Toast消息

我正在製作andengine動態壁紙。問題是，因爲我有很多紋理，我的牆紙onresume的加載需要很多時間。我如何減少這個時間。此外，我想在onresume（）方法中插入Toast消息，以便用戶不會因加載緩慢而感到惱火。但是，當我嘗試在簡歷上放置吐司消息時，我似乎得到了looper.prepare（）錯誤。我應該如何把吐司消息？如何在Andengine Live Wallpaper服務中使用Toast消息

public void onResumeGame() { 
    super.onResumeGame(); 
    getEngine().start(); 
    Toast.makeText(NightSkyLWPService.this, "Loading Wallpaper", Toast.LENGTH_LONG).show();  
}

runOnUiThread不在服務運行。 –

嘗試'Toast.makeText（getApplicationContext（），「加載壁紙」，Toast.LENGTH_LONG）.show（）;' – Alexey

仍然收到錯誤.. –

您需要在UI線程上運行它，試試這個：

public void onResumeGame() { 
    super.onResumeGame(); 
    getEngine().start(); 
    runOnUiThread(new Runnable() { 
     @Override 
     public void run() { 
       Toast.makeText(NightSkyLWPService.this, "Loading Wallpaper", Toast.LENGTH_LONG).show();  
     } 
    }); 
}
