Android - 具有三个列表视图的片段崩溃，内存不足错误

标签： android android-listview

我已经制作了这个简单的片段布局 - 

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

    <ListView
        android:id="@+id/listView_airplanes"
        android:layout_width="170dp"
        android:layout_height="wrap_content" >
    </ListView>

    <ListView
        android:id="@+id/listView_fruits"
        android:layout_width="170dp"
        android:layout_height="wrap_content" >
    </ListView>

    <ListView
        android:id="@+id/listView_animals"
        android:layout_width="170dp"
        android:layout_height="wrap_content" >
    </ListView>

</LinearLayout>

现在，每个列表视图中的每一行都应显示位于资源文件夹中的图像。

所以每个列表项的布局都是这样的 - 

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

    <ImageView
        android:id="@+id/imageView_image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/@null" />

</LinearLayout>

现在，我为每个listview制作了一个布局，但它看起来都一样 - 只有一个imageview。

现在代码 - 

        @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

View v = inflater.inflate(R.layout.listsviews,container, false);

 lvTops = (ListView) v.findViewById(R.id.listView_airplanes);
         lvBottoms = (ListView) v.findViewById(R.id.listView_fruits);
         lvMiddle = (ListView) v.findViewById(R.id.listView_animals);

dbHand = new DbHandler(getActivity());

Cursor topCursor = dbHand.queryByCat("airplanes);
Cursor bottomCursor = dbHand.queryByCat("fruits");
Cursor middleCursor = dbHand.queryByCat("animals");


            getActivity().startManagingCursor(topCursor);


            getActivity().startManagingCursor(bottomCursor);


            getActivity().startManagingCursor(middleCursor);

            topadp = new TopsAdptor(getActivity(), topCursor);
            lvTops.setAdapter(topadp);

            botadp = new BottomsAdaptor(getActivity(), bottomCursor);
            lvBottoms.setAdapter(botadp);

            middleCursor = new MiddleAdptor(getActivity(), topCursor);
            lvMiddle.setAdapter(topadp);



}

正如您所看到的，我为每个列表视图使用自定义适配器类。

所有适配器代码都相同 - 这是一个例子 - 

    class BottomsAdaptor extends CursorAdapter {

    public BottomsAdaptor(Context context, Cursor c) {
        super(context, c);
        // TODO Auto-generated constructor stub
    }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {
        // TODO Auto-generated method stub
        String pic = cursor.getString(cursor
                .getColumnIndex(Constants.ITEM_PIC_URL));

        ImageView iv = (ImageView) view.findViewById(R.id.imageView_lv_bottom);




        try {
            InputStream ims;
            ims = getActivity().getAssets().open(pic);
            Drawable d = Drawable.createFromStream(ims, null);
            iv.setImageDrawable(d);

        } catch (IOException e) {


            e.printStackTrace();
        }


    }

    @Override
    public View newView(Context arg0, Cursor arg1, ViewGroup parent) {
        // TODO Auto-generated method stub
        return getActivity().getLayoutInflater().inflate(R.layout.bottoms_list_item, parent,
                false);
    }

}

现在的问题是，在少量图像中（让每个列表视图为5）它确实可以正常工作，但是当我在每个列表视图中提高图像数量时，然后向下滚动一个应用程序崩溃的列表视图，并在日志中显示 - 

java.lang.OutOfMemoryError

现在我也试过像这样使用asynctask - 

    class Asyinc extends AsyncTask<Void, Void, Void>{
     Cursor topCursor;
     Cursor bottomCursor;
     Cursor middleCursor;

    @Override
    protected Void doInBackground(Void... params) {

         topCursor = dbHand.queryByCat("tops");
         bottomCursor = dbHand.queryByCat("bottoms");
         middleCursor;= dbHand.queryByCat("dress");


        getActivity().startManagingCursor(topCursor);

        getActivity().startManagingCursor(bottomCursor);
        getActivity().startManagingCursor(middleCursor);


        return null;
    }

    @Override
    protected void onPostExecute(Void result) {

        super.onPostExecute(result);


        topadp = new TopsAdptor(getActivity(), topCursor);
        lvTops.setAdapter(topadp);


        botadp = new BottomsAdaptor(getActivity(), bottomCursor);
        lvBottoms.setAdapter(botadp);


        middleatp = new DressedAdptor(getActivity(), middleCursor);
        lvMiddle.setAdapter(middleatp);




    }

}

但是在尝试滚动列表视图时，应用程序仍然崩溃。

任何想法我怎么能解决这个问题？ 感谢您提供任何帮助

当我使用asynctask -

时，这里出现了logcat错误

1 个答案:

答案 0 :(得分：1)

图像尺寸太大或其他东西。你可以尝试添加

android:largeHeap="true"

在清单文件中的应用程序标记上。看看是否能解决问题。虽然不能保证解决它。如上所述：http://developer.android.com/guide/topics/manifest/application-element.html

但它确实修复了我的应用中的内存不足错误。看看这对你有帮助吗？
