如何检查项目是否存在于另一个listview中？

ListView sourceListView = findViewById(R.id.sourceListView);
ListView targetListView = findViewById(R.id.targetListView);

ListAdapter sourceAdapter = sourceListView.getAdapter();
ListAdapter targetAdapter = targetListView.getAdapter();

int sourceItemCount = sourceAdapter.getCount();
int targetItemCount = targetAdapter.getCount();

for (int i = 0; i < sourceItemCount; i++) {
    Object sourceItem = sourceAdapter.getItem(i);
    boolean existsInTarget = false;

    for (int j = 0; j < targetItemCount; j++) {
        Object targetItem = targetAdapter.getItem(j);

        if (sourceItem.equals(targetItem)) {
            existsInTarget = true;
            break;
        }
    }

    if (existsInTarget) {
        // 项目存在于目标ListView中
        // 可以在此处执行相应的操作
    } else {
        // 项目不存在于目标ListView中
        // 可以在此处执行相应的操作
    }
}
