ListView的Item樣式自定義

要自定義ListView的Item樣式，可以通過創(chuàng)建一個自定義的布局文件來定義每個Item的外觀和布局。以下是一個簡單的示例：

1. 創(chuàng)建一個名為"list_item_layout.xml"的布局文件，定義Item的外觀和布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:padding="16dp">

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:src="@drawable/ic_launcher_background"/>

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="16dp"
        android:text="Item Text"
        android:textSize="16sp"/>

</LinearLayout>

2. 在適配器中使用這個自定義的布局文件來為ListView的每個Item設置樣式：

public class CustomAdapter extends ArrayAdapter<String> {

    private Context mContext;
    private List<String> mList;

    public CustomAdapter(Context context, List<String> list) {
        super(context, R.layout.list_item_layout, list);
        this.mContext = context;
        this.mList = list;
    }

    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        View view = convertView;
        if (view == null) {
            LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            view = inflater.inflate(R.layout.list_item_layout, parent, false);
        }

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

        imageView.setImageResource(R.drawable.ic_launcher_foreground);
        textView.setText(mList.get(position));

        return view;
    }
}

3. 在Activity中設置ListView的適配器為自定義的適配器：

public class MainActivity extends AppCompatActivity {

    private ListView listView;

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

        listView = findViewById(R.id.listView);

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

        CustomAdapter adapter = new CustomAdapter(this, dataList);
        listView.setAdapter(adapter);
    }
}

通過以上步驟，就可以自定義ListView的Item樣式了?？梢愿鶕枨笮薷淖远x布局文件和適配器中的代碼來實現不同樣式的Item。
