我有问题我不明白。当我到达以下代码片段时

public class MatchViewActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.d("OnCreate in MatchViewActivity","1");
        setContentView(R.layout.activity_match_view); <--- Crash occurrs here
        Log.d("","2");
        Intent intent = getIntent();

我总是在模拟器中收到以下错误：

10-07 18:41:39.012: E/dalvikvm-heap(1099): Out of memory on a 3686416-byte allocation.

我可以在 logcat 中找到一些行：

我检查了“activity_match_view”确实存在。这里发生了什么？

对应的布局文件：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/main_background" >

    <ListView
        android:id="@+id/matchView_ListView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" 
        android:cacheColorHint="#00000000">
    </ListView>

</FrameLayout>

该错误是因为操作系统试图为您的背景创建的位图可能太大，因此它会耗尽资源，还要确保为模拟器分配的内存具有不错的价值，否则它可能会用完容易记忆。

希望这可以帮助。

问候！

你的@drawable/main_background 有多大 加载可能太大了。每个位图都在你的记忆中，所以请提供小图片

对背景图像使用 .jpeg/.jpg 格式而不是 .png 图像，因为在 android 中重新使用资源时，.png 与 .jpeg/.jpg 图像相比需要更多的堆内存。
