本文介绍了一个简单的图片显示程序在Android模拟器上遇到的内存溢出问题及解决方法。通过对模拟器的VM Heap大小进行调整，从16增加到128，解决了在加载大量图片资源时出现的内存不足问题。

今天弄个简单的图片显示程序</p>

LinearLayout linearLayout =(LinearLayout)this.findViewById(R.id.LinearLayout1);
        for(int i=0;i<imagePath.length;i++)
        {
        	img[i]=new ImageView(this);
        	img[i].setImageResource(imagePath[i]);
        	img[i].setPadding(5, 5, 5, 5);
        	LayoutParams layoutParams=new LayoutParams(253,148);
        	img[i].setLayoutParams(layoutParams);
        	linearLayout.addView(img[i]);
        }

在物理机运行正常，但是在模拟器运行出现下面的问题：
