为什么我的Android应用程序中的页面显示不正确？

我正在写一个Android应用程序。它有两页。第二个页面应该是一个充满图像按钮的页面。但是，当我在emulator中运行我的应用程序并转到第二个页面时，该页面不会显示。为什么?

我得到一个错误：

Android logcat文本：0X00000000处的致命信号11（SIGSEGV）（代码==1），线程614（com.s

这是整个LOGCAT

从日志中，您可以看到解码图像时出现内存不足错误：

01-14 09:08:19.875: E/dalvikvm-heap(614): Out of memory on a 7077904-byte allocation.

对于emulator设备配置文件分配的内存，可能（错误地）使用的映像太大。您可以尝试增加设备的堆大小（窗口-->AVD管理器-->虚拟设备-->编辑：硬件属性）

建立完整的日志猫！！一些适用的代码也不会有什么坏处。如果你没有用代码和日志输出写一个完整的问题，就帮不了你。对不起，我是新手，任何帮助都会非常感激。一些帮助任何人，请01-14 09:08:19.875:E/dalvikvm堆（614）：7077904字节分配的内存不足。
