在Android studio中使用Listview控件和Fragment编写出三行两列的页面

首先，需要在XML布局文件中添加一个ListView控件和一个Fragment容器：

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">

    <ListView
        android:id="@+id/listView"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"/>

    <FrameLayout
        android:id="@+id/fragmentContainer"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="2"/>

</LinearLayout>

然后，在Fragment容器中添加一个GridView控件，并设置适配器：

public class MyFragment extends Fragment {

    GridView gridView;

    public MyFragment() {
        // Required empty public constructor
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_my, container, false);

        gridView = view.findViewById(R.id.gridView);
        gridView.setAdapter(new MyAdapter(getActivity()));

        return view;
    }

    private class MyAdapter extends BaseAdapter {

        private Context context;
        private LayoutInflater inflater;

        public MyAdapter(Context context) {
            this.context = context;
            inflater = LayoutInflater.from(context);
        }

        @Override
        public int getCount() {
            return 6;
        }

        @Override
        public Object getItem(int position) {
            return null;
        }

        @Override
        public long getItemId(int position) {
            return 0;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            if (convertView == null) {
                convertView = inflater.inflate(R.layout.grid_item, parent, false);
            }

            ImageView imageView = convertView.findViewById(R.id.imageView);
            TextView textView = convertView.findViewById(R.id.textView);

            imageView.setImageResource(R.drawable.ic_launcher_background);
            textView.setText("Item " + (position + 1));

            return convertView;
        }
    }
}

最后，在MainActivity中设置ListView的适配器，并在列表项点击时切换Fragment：

public class MainActivity extends AppCompatActivity {

    ListView listView;
    FrameLayout fragmentContainer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        listView = findViewById(R.id.listView);
        fragmentContainer = findViewById(R.id.fragmentContainer);

        listView.setAdapter(new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, new String[]{"Fragment 1", "Fragment 2", "Fragment 3"}));
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Fragment fragment = new MyFragment();
                FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
                transaction.replace(R.id.fragmentContainer, fragment);
                transaction.commit();
            }
        });
    }

}

注意要修改MyAdapter中的数据源和布局文件，以及在GridView中设置列数。
