listview控件怎么設(shè)置橫向多個列

要在ListView控件中設(shè)置橫向多個列，可以使用GridView作為ListView的子控件。

以下是一個示例：

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);

        // 初始化數(shù)據(jù)
        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);
        }

        // 設(shè)置適配器
        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;
        }
    }
}

這樣就可以在ListView中顯示橫向多個列的數(shù)據(jù)了。每個Item使用GridView來顯示多列數(shù)據(jù)，通過設(shè)置GridView的numColumns屬性為auto_fit可以自動根據(jù)屏幕大小調(diào)整顯示列數(shù)。用數(shù)組適配器ArrayAdapter來顯示每個格子的數(shù)據(jù)。
