要在ListView控件中设置横向多个列，可以使用GridView作为ListView的子控件。
以下是一个示例：
activity_main.xml:
<ListView android:id="@+id/listView" android:layout_width="match_parent" android:layout_height="match_parent"/>list_item.xml:
<GridView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/gridView" android:layout_width="match_parent" android:layout_height="wrap_content" android:columnWidth="100dp" android:numColumns="auto_fit" android:verticalSpacing="10dp" android:horizontalSpacing="10dp" android:stretchMode="columnWidth" android:gravity="center"/>MainActivity.java:
public class MainActivity extends AppCompatActivity { private ListView listView; private List<List<String>> data; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); listView = findViewById(R.id.listView); // 初始化数据 data = new ArrayList<>(); for (int i = 0; i < 20; i++) { List<String> row = new ArrayList<>(); for (int j = 0; j < 3; j++) { row.add("Item " + i + "-" + j); } data.add(row); } // 设置适配器 MyAdapter adapter = new MyAdapter(data); listView.setAdapter(adapter); } private class MyAdapter extends BaseAdapter { private List<List<String>> data; public MyAdapter(List<List<String>> data) { this.data = data; } @Override public int getCount() { return data.size(); } @Override public Object getItem(int position) { return data.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { if (convertView == null) { convertView = LayoutInflater.from(MainActivity.this).inflate(R.layout.list_item, parent, false); } GridView gridView = convertView.findViewById(R.id.gridView); ArrayAdapter<String> gridAdapter = new ArrayAdapter<>(MainActivity.this, android.R.layout.simple_list_item_1, data.get(position)); gridView.setAdapter(gridAdapter); return convertView; } }}这样就可以在ListView中显示横向多个列的数据了。每个Item使用GridView来显示多列数据，通过设置GridView的numColumns属性为auto_fit可以自动根据屏幕大小调整显示列数。用数组适配器ArrayAdapter来显示每个格子的数据。
