一个不好解的内存有关问题

一个不好解的内存问题最近遇到一个应用方面的内存问题，没一点解决的思路，希望大家可以讨论一下。问题描述如

一个不好解的内存问题
最近遇到一个应用方面的内存问题，没一点解决的思路，希望大家可以讨论一下。
问题描述如下：
在写一个系统设置，其中包括了声音设置，时间设置等，首先用户点系统设置，进入我们的系统设置主界面，然后用户可以在不同的设置之间，进行切换，代码简述如下。

Java code

public class TimeMainActivity extends Activity                             implements OnClickListener{    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        //窗口全屏显示        requestWindowFeature(Window.FEATURE_NO_TITLE);        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,                WindowManager.LayoutParams.FLAG_FULLSCREEN);                setContentView(R.layout.layout_time);        System.out.println("TimeMainActivity");        InitView();            }    private void InitView() {                    }    public void onClick(View v) {        // TODO Auto-generated method stub        m_event.onClick(v);            }}

Java code

public class VolMainActivity extends Activity implements OnClickListener {    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        // 窗口全屏显示        requestWindowFeature(Window.FEATURE_NO_TITLE);        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,                WindowManager.LayoutParams.FLAG_FULLSCREEN);        setContentView(R.layout.layout_vol);        System.out.println("VolMainActivity");        InitView();    }    private void InitView() {            }    public void onClick(View v) {        // TODO Auto-generated method stub        m_event.onClick(v);    }}

以上是两个分界面的代码简述，当在两个分界面之间切换时，输出如下log信息。

通过以上信息发现，是分配不了内存造成的，经过分析发现问题出在setContentView函数中，因为在我们的布局文件中包含了很多图片文件，drawable文件夹的总大小也只有625K,将该程序放在htc的某型手机上，删除其中的一，两图片，可以正常运行，但要是放在我们自己的开发板上，要删除一个半才能运行。
不知道各位有什么好的主意没。

[解决办法]
牛XX了，写XML文件都能写出OOM来
[解决办法]

探讨
我也不想这样牛ＸＸ，可现在就是解决不了这个问题，郁闷死，大家都没遇见过吗。

[解决办法]
。。。xml是咋样的？
