Java 背景图像不显示

因此，在修改现有框架时，我尝试更改背景图像。我不仅从资产文件夹中删除了该图像，还调用了新的背景图像。但出于某种原因，旧的背景才是最明显的

这是加载图像的位置

      public static void load() {
            icLauncher = loadBitmap("ic_launcher_36",false);
       dodgingfire_welcome = loadBitmap("dodgingfire_welcome.png", false);
            block = loadBitmap("block.png", false);
            cloud1 = loadBitmap("cloud1.png", true);
            cloud2 = loadBitmap("cloud2.png", true);
            duck = loadBitmap("duck.png", true);
            grass = loadBitmap("grass.png", false);

这就是调用方法的地方

     @Override
        public void render(Painter g) {
    g.drawImage(Assets.dodgingfire_welcome, 0, 0);
            startButton.render(g);
           scoreButton.render(g);
        }

这些是完整的课程

package rect.draw.gametest.model.state;

import android.view.MotionEvent;

import rect.draw.gametest.Assets;
import rect.draw.gametest.model.util.Painter;
import rect.draw.gametest.model.util.UIButton;


public class MenuState extends State {
    private UIButton startButton, scoreButton;

    @Override
    public void init() {
        startButton = new UIButton(316, 227, 484, 286, Assets.start,
                Assets.startDown);
        scoreButton = new UIButton(316, 300, 484, 359, Assets.score,
                Assets.scoreDown);
    }

    @Override
    public void update(float delta) {
    }

    @Override
    public void render(Painter g) {

        g.drawImage(Assets.dodgingfire_welcome, 0, 0);
        startButton.render(g);
       scoreButton.render(g);
    }

    @Override
    public boolean onTouch(MotionEvent e, int scaledX, int scaledY) {
        if (e.getAction() == MotionEvent.ACTION_DOWN) {
            startButton.onTouchDown(scaledX, scaledY);
            scoreButton.onTouchDown(scaledX, scaledY);
        }
        if (e.getAction() == MotionEvent.ACTION_UP) {
            if (startButton.isPressed(scaledX, scaledY)) {
                startButton.cancel();
                setCurrentState(new PlayState());
            } else if (scoreButton.isPressed(scaledX, scaledY)) {
                scoreButton.cancel();
                setCurrentState(new ScoreState());
            } else {
                startButton.cancel();
                scoreButton.cancel();
            }
        }
        return true;
    }
}
