自定义布局（动态实现listview添加表格布局）

实现自定义布局可以使用自定义的Adapter，并在getView()方法中动态添加表格布局。

首先，在res/layout文件夹下新建一个xml文件，命名为table_item.xml，用于定义表格布局的样式。例如：

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:stretchColumns="0,1,2">

    <TableRow>
        <TextView
            android:text="Name"
            android:padding="5dp"
            android:textSize="18sp"
            android:textStyle="bold" />

        <TextView
            android:text="Age"
            android:padding="5dp"
            android:textSize="18sp"
            android:textStyle="bold" />

        <TextView
            android:text="Gender"
            android:padding="5dp"
            android:textSize="18sp"
            android:textStyle="bold" />
    </TableRow>

    <TableRow>
        <TextView
            android:id="@+id/tv_name"
            android:padding="5dp"
            android:textSize="16sp" />

        <TextView
            android:id="@+id/tv_age"
            android:padding="5dp"
            android:textSize="16sp" />

        <TextView
            android:id="@+id/tv_gender"
            android:padding="5dp"
            android:textSize="16sp" />
    </TableRow>

</TableLayout>

然后，在Java代码中创建一个自定义的Adapter，重写getView()方法，动态添加表格布局：

public class TableAdapter extends ArrayAdapter<Person> {

    private int resource;

    public TableAdapter(Context context, int resource, List<Person> objects) {
        super(context, resource, objects);
        this.resource = resource;
    }

    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        if(convertView == null){
            convertView = LayoutInflater.from(getContext()).inflate(resource, parent, false);
        }

        TextView tvName = convertView.findViewById(R.id.tv_name);
        TextView tvAge = convertView.findViewById(R.id.tv_age);
        TextView tvGender = convertView.findViewById(R.id.tv_gender);

        Person person = getItem(position);

        tvName.setText(person.getName());
        tvAge.setText(String.valueOf(person.getAge()));
        tvGender.setText(person.getGender());

        return convertView;
    }
}

最后，在Activity中设置ListView的Adapter为自定义的Adapter即可：

public class MainActivity extends AppCompatActivity {

    private ListView listView;
    private List<Person> personList;

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

        listView = findViewById(R.id.list_view);

        personList = new ArrayList<>();
        personList.add(new Person("Tom", 20, "Male"));
        personList.add(new Person("Lucy", 18, "Female"));
        personList.add(new Person("Jack", 22, "Male"));

        TableAdapter adapter = new TableAdapter(this, R.layout.table_item, personList);
        listView.setAdapter(adapter);
    }
}
