我有一个游戏应用程序需要很长时间才能加载。我以前在说明我的游戏时没有滞后，但现在是这样，我怀疑有些东西挂了。是否有可能由于我加载图像的方式而挂起？这是我所拥有的：

在 onCreate() 我有：

v = new SView(this);                      // Creates my new SurfaceView
a = new Accelerator();                    // Adds the accelerometer
new loadPhotos().execute("");             // Initiates the AsyncTask posted below
new handleStuff().execute("");            // starts the generation of the game map
startTime = System.currentTimeMillis();   // Used to generate time lasted
setContentView(v);                        // Sets contentView to the SurfaceView


public class loadPhotos extends AsyncTask<String, Integer, String>
{
@Override

protected String doInBackground(String... arg0) {

    return null;
}

@Override
protected void onPreExecute() {
    super.onPreExecute();
    Log.d(null, "!!!!!!!!!!!!!----------Starting Load-----------!!!!!!!!!1");
    player = BitmapFactory.decodeResource(getResources(), R.drawable.player);
    playerOpaque = BitmapFactory.decodeResource(getResources(), R.drawable.player_opaque);
    livesBM = BitmapFactory.decodeResource(getResources(), R.drawable.lives);
    playerMissile = BitmapFactory.decodeResource(getResources(), R.drawable.player_missle);
    missileButton = BitmapFactory.decodeResource(getResources(), R.drawable.missile_button);
    playerBullet = BitmapFactory.decodeResource(getResources(), R.drawable.bullet);
    enemyBullet = BitmapFactory.decodeResource(getResources(), R.drawable.enemy_bullet);
    enemyMissile = BitmapFactory.decodeResource(getResources(), R.drawable.enemy_missle);
    enemy = BitmapFactory.decodeResource(getResources(), R.drawable.enemy);
    explosionBig = BitmapFactory.decodeResource(getResources(), R.drawable.explosion);
    lastESpawn = System.currentTimeMillis();
    background = BitmapFactory.decodeResource(getResources(), R.drawable.background_clearsky);
    cloudBM1 = BitmapFactory.decodeResource(getResources(), R.drawable.cloud1);
    cloudBM2 = BitmapFactory.decodeResource(getResources(), R.drawable.cloud2);
    Log.d(null, "!!!!!!!!!!!!!----------Ending Load-----------!!!!!!!!!1");
}

}

这是我的 LogCat

尝试如下加载图像在图像视图中 iv.setImageResource(R.drawable.imagename);

这比通过decoderresource加载要快得多。你的每一个图片加载都有这样的方法。

您正试图通过您无法访问的方式访问您的UI资源doInBackground。这需要 inonPostExecute()或其他Async方法，但我什至不确定你想要/需要一个AsyncTask。您可以设置images使用ImageView 方法并将它们加载到您的方法中Activity
