扩展类<unknown>（ImageView）Honeycomb </unknown>时出错

时间：2014-05-29 16:11:20

标签： android layout

我有这个错误：

05-29 16:58:38.733: E/AndroidRuntime(454): android.view.InflateException: Binary XML file line #17: Error inflating class <unknown>

第17行是这一行：

    <ImageView
        android:id="@+id/imageEventCover"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/event_cover"
        android:scaleType="centerCrop" />

我正在尝试在API 12上运行它，它正在崩溃。它适用于API＆gt; 14（未在11或13上测试）。

有什么问题？

我的完整xml文件：

        android:background="@drawable/shadow"/>
</LinearLayout>

这是扩展此XML的适配器：

public View getView(int position, View convertView, ViewGroup parent)
{
    ViewHolder holder;

    if(convertView == null)
    {
        convertView = inflater.inflate(R.layout.list_events, null);
        holder = new ViewHolder();

        holder.eventName = (NewTextView) convertView.findViewById(R.id.textEventName);
        holder.eventCoverProgress = (ProgressBar) convertView.findViewById(R.id.progressBar);
        holder.eventDuration = (NewTextView) convertView.findViewById(R.id.textEventDuration);
        holder.eventPlace = (NewTextView) convertView.findViewById(R.id.textEventPlace);
        holder.eventCover = (ImageView) convertView.findViewById(R.id.imageEventCover);
        holder.eventApproved = (NewTextView) convertView.findViewById(R.id.textIsEnrolled);
    }
    else
    {
        holder = (ViewHolder) convertView.getTag();
    }
    ...

这是完整的堆栈跟踪：

这是一个记忆问题。

Stacktrace证明了这一点：

05-29 17:23:17.173: E/dalvikvm-heap(527): Out of memory on a 1024016-byte allocation.

答案 1 :(得分：0)

由于

，您收到此错误 
android:src="@drawable/event_cover"

event_cover图像的大小非常大。这就是你收到此错误的原因。

解决方案

将您的图片设为KB而不是MB，并在清单文件的应用标记中添加

android:largeheap="true";
