如何为一个扩展了ArrayAdapter<HashMap<String，String>>的活动扩展AppCompatActivity？

implementation 'androidx.appcompat:appcompat:1.4.0'

public class MyActivity extends AppCompatActivity {
    // 活动的代码逻辑
}

public class MyAdapter extends ArrayAdapter<HashMap<String, String>> {
    // 适配器的代码逻辑
}

public class MyActivity extends AppCompatActivity {
    private MyAdapter mAdapter;

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

        // 初始化适配器
        mAdapter = new MyAdapter(this, R.layout.item_layout, yourHashMapList);

        // 设置适配器
        ListView listView = findViewById(R.id.listView);
        listView.setAdapter(mAdapter);
    }
}
