Canvas: 尝试绘制太大的位图（151099200字节）

Question

我有一个Android应用程序，正在尝试绘制太大的内容而崩溃。我查看了在stackoverflow上发布的类似问题的答案，但是没有一个解决方案适用于我。所有图像都在各自的文件夹中（请参见附加的图像）。因此，我现在对导致崩溃的原因感到困惑。

我在这里使用了ListView：

    public class AttractionsAdapter  extends ArrayAdapter<Attractions> {

    public AttractionsAdapter(Context context, ArrayList<Attractions> attractions) {
        super(context, 0, attractions);
    }


    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // Check if an existing view is being reused, otherwise inflate the view
        View listView = convertView;
        if (listView == null) {
            listView = LayoutInflater.from(getContext()).inflate(
                    R.layout.list_item_layout, parent, false);
        }
    Attractions currentAttraction = getItem(position);

    TextView attractionTextView = listView.findViewById(R.id.attraction_name_view);

        attractionTextView.setText(currentAttraction.getName());


    // Find the ImageView in the list_item.xml layout with the ID image.
    ImageView imageView = (listView.findViewById(R.id.image));

        if (currentAttraction.hasImage()) {

        imageView.setImageResource(currentAttraction.getImageId());
        imageView.setVisibility(View.VISIBLE);
    } else {

        imageView.setVisibility(View.GONE);
    }

        return listView;
}

}

以及我的碎片：

public class ClubsFragment extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstances) {
        View rootView = inflater.inflate(R.layout.attraction_layout, container, false);

        ArrayList<Attractions> attractions = new ArrayList<>();
        attractions.add(new Attractions(R.string.club_one, R.drawable.shakers));
        attractions.add(new Attractions(R.string.club_two,R.drawable.jojo));
        attractions.add(new Attractions(R.string.club_three, R.drawable.maia));
        attractions.add(new Attractions(R.string.club_four, R.drawable.great));


        AttractionsAdapter adapter = new AttractionsAdapter(getActivity(), attractions);

        ListView listView = rootView.findViewById(R.id.list);

        listView.setAdapter(adapter);
        return rootView;
    }

}

我的布局：

<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"

<ImageView
    android:id="@+id/image"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

<RelativeLayout
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="true"
    android:layout_toRightOf="@id/image"
    android:orientation="vertical"
    android:paddingLeft="16dp">

    <TextView
        android:id="@+id/attraction_name_view"
        android:layout_width="match_parent"
        android:layout_height="44dp"
        android:layout_weight="1"
        android:gravity="top"
        android:textAppearance="?android:textAppearanceMedium"
        android:textColor="@android:color/white"
        tools:text="one" />

    <ImageView
        android:layout_width="24dp"
        android:layout_height="24dp"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:layout_marginRight="16dp" />
</RelativeLayout>

请考虑使用实际的代码片段而不是您IDE的截图。 - Giorgos Neokleous

请勿将代码作为截图分享，因为它无法被搜索。请发布代码和堆栈跟踪信息。 - patrick.elmquist

显示异常堆栈跟踪。 - Vladyslav Matviienko

你的一些ListView绘制存在问题。请展示使用ListView的代码以及该ListView项的布局。 - Vladyslav Matviienko

它在压缩状态下为4.4mb，但在内存中可能会更大。 - Bracadabra

Answer 1

我通过移除所有超过2mb的图片来解决了这个问题。现在应用程序不再崩溃。 感谢@Bracadabra 和@Vladyslav的评论。他们帮助我找出了问题所在并进行了修复。
