问题描述
我有一个android应用，尝试绘制太大时崩溃了.我已经查看了在stackoverflow上发布的类似问题的答案，但是没有一种解决方案适合我.所有图像都在各自的文件夹中(请参阅附件图像)，所以现在我对导致崩溃的原因不知所措
I have an android app and it's crashing with trying to draw too large. I have looked at the answers to similar questions posted on stackoverflow but none of the solutions work for me. All the images are in respective folders(see attached image) So I am at a loss for what's causing the crash now

我在这里使用ListView:
I use ListView here:
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;
}
}
和我的片段:
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;
}
}
和我的布局:
<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>
