试图在Onclick上使用一系列图像

Question

我不知道我在这里做错了什么

//This is the Bullet Class. Here All I need is the Y position (because the Bullet is going only Y. The image which is in my drawable hdpi folder contains the image of my bullet.



public class Bulletbun extends GameObject  {

private int deltaY;


private android.media.Image img;


public Bulletbun(final int xPos, final int yPos, final Image img){


this.img= img;
this.xPos=xPos;
this.yPos=yPos;

}
public Bulletbun(float f, int i, int j, String string) {
    // TODO Auto-generated constructor stub
}
@Override
public void draw(Graphics g){
    g.drawImage (img, xPos, yPos, null);

}

@Override
void update() {
    // TODO Auto-generated method stub

}
}



}
}

//试图让它从这里开始......这是我的OnClick。我想要的是当我触摸我制作的按钮时，图像会在屏幕的Y位置拍摄。此外，如果我多次击中它会射击不止一个（5）。但也要摧毁屏幕外的那些以节省内存。

        @Override
        public void onClick(View v) {    //+sound
            // TODO Auto-generated method stub  //+sound


            Bulletbun Bulletbunny= new Bulletbun(bunbutt.getX()+20, 4,4,      "images/air_bunny.png");



            if (barrelblast != 0)
                sp.play(barrelblast, 1, 1, 0, 0, 1);  //+sound

            Vibrator vibe = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);
            vibe.vibrate(90);


            smoke.setVisibility(View.VISIBLE);



                Handler delayedAction = new Handler();

                delayedAction.postDelayed(new Runnable() {

                public void run() {

                smoke.setVisibility(View.INVISIBLE);


     //This is my GameObject Class 

package com.ramy.fallingbarrels;

import com.badlogic.gdx.Graphics;

import android.media.Image;

public abstract class GameObject {

protected Image img;
protected int xPos;
protected int yPos;

abstract void draw (Graphics g);

abstract void update();






public Image getImg() {
    return img;
}
public void setImg(Image img) {
    this.img = img;
}
public int getxPos() {
    return xPos;
}
public void setxPos(int xPos) {
    this.xPos = xPos;
}
public int getYpos() {
    return yPos;
}
public void setYpos(int ypos) {
    this.yPos = ypos;
}

//我试图按照教程。如果我在这里做错了，请告诉我。如果有更好的方法来做我描述的，请告诉我。
