android 列表视图项目高度

Android开发中，列表视图是一种常见的UI组件，用于展示大量数据。列表视图项目的高度是指每个列表项在垂直方向上的尺寸。在本文中，我们将探讨Android列表视图项目高度的相关知识，并提供一个案例代码来帮助读者更好地理解。

xml
    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    />

java
ListView listView = findViewById(R.id.listView);
LayoutParams layoutParams = new LayoutParams(LayoutParams.MATCH_PARENT, 200);
listView.setLayoutParams(layoutParams);

java
public class CustomAdapter extends BaseAdapter {
    private Context context;
    private List data;
    private List heights;
    public CustomAdapter(Context context, List data, List heights) {
        this.context = context;
        this.data = data;
        this.heights = heights;
    }
    @Override
    public int getCount() {
        return data.size();
    }
    @Override
    public Object getItem(int position) {
        return data.get(position);
    }
    @Override
    public long getItemId(int position) {
        return position;
    }
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            convertView = LayoutInflater.from(context).inflate(R.layout.list_item, parent, false);
        }
        TextView textView = convertView.findViewById(R.id.textView);
        textView.setText(data.get(position));
        LinearLayout.LayoutParams layoutParams = (LinearLayout.LayoutParams) convertView.getLayoutParams();
        layoutParams.height = heights.get(position);
        convertView.setLayoutParams(layoutParams);
        return convertView;
    }
}
