package com.lala.image;

import com.lala.ContextStore;

import android.R;
import android.content.Context;
import android.content.res.Resources;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.view.View;

public class Stationary implements Image{

    View v;
    Context context;
    String image;
    Bitmap img;

    float x;
    float y;


    public Stationary(Context context, String image) {
        // TODO Auto-generated constructor stub
        this.image = image;
        this.context = context;
        this.setImage(image);
    }

    public void setImage(String image) {
        // TODO Auto-generated method stub

        if(image=="bdfs"){
            this.img = BitmapFactory.decodeResource(context.getResources(), R.id.icon);
        }
        else if(image=="ssdfsdf"){
            this.img = BitmapFactory.decodeResource(context.getResources(), R.id.icon); 
        }
        else if(image=="asfdsdf"){
            this.img = BitmapFactory.decodeResource(context.getResources(), R.id.icon); 
        }
        else{
            this.img = BitmapFactory.decodeResource(context.getResources(), R.id.icon); 
        }
    }

    public Bitmap getImage(){
        return img;
    }

    public float getX() {
        // TODO Auto-generated method stub
        return this.x;
    }

    public float getY() {
        // TODO Auto-generated method stub
        return this.y;
    }

    public void setX(float x) {
        // TODO Auto-generated method stub
        this.x = x;
    }

    public void setY(float y) {
        // TODO Auto-generated method stub
        this.y = y;
    }

}

I am not sure how to use context and resources in a class when it is called from another activity.

I am getting an error message when the context or resources are called.

Any code to assist would be very welcome.

Thanks for your time

It looks like the problem is not with the context but with the way you’re calling BitmapFactory.decodeResource(). I see you’re passing in R.id.icon which is an ID of an element in a layout. You need to pass in a reference to an image. Something like R.drawable.your_bitmap instead.
