如何在Android中以编程方式使列表视图项左右对齐

<ListView
    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

public class CustomAdapter extends ArrayAdapter<String> {
    private Context mContext;
    private List<String> mData;

    public CustomAdapter(Context context, List<String> data) {
        super(context, R.layout.list_item, data);
        mContext = context;
        mData = data;
    }

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

        TextView textView = listItem.findViewById(R.id.textView);
        textView.setText(mData.get(position));

        return listItem;
    }
}

<TextView
    android:id="@+id/textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="start"
    android:textSize="16sp" />

public class MainActivity extends AppCompatActivity {
    private ListView mListView;

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

        mListView = findViewById(R.id.listView);

        List<String> data = new ArrayList<>();
        data.add("Item 1");
        data.add("Item 2");
        data.add("Item 3");

        CustomAdapter adapter = new CustomAdapter(this, data);
        mListView.setAdapter(adapter);

        mListView.setDivider(null);
        mListView.setDividerHeight(0);
        mListView.setPadding(0, 0, 0, 0);
    }
}
