在android自定义listview内扩展textview高度

public class ExpandableTextView extends TextView {
    private boolean isExpanded = false;

    public ExpandableTextView(Context context) {
        super(context);
    }

    public ExpandableTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public ExpandableTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        if (isExpanded) {
            // 如果TextView需要展开，直接使用父类的onMeasure方法测量高度
            super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        } else {
            // 如果TextView不需要展开，将高度设置为一个较小的值，例如0
            int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
            super.onMeasure(widthMeasureSpec, expandSpec);
        }
    }

    public void setExpanded(boolean expanded) {
        isExpanded = expanded;
    }
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // 其他代码...

    ExpandableTextView textView = convertView.findViewById(R.id.expandable_text_view);
    textView.setText(data.get(position));
    textView.setExpanded(isExpanded(position)); // 根据需要展开的位置设置展开状态

    // 其他代码...
}

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        ExpandableTextView textView = view.findViewById(R.id.expandable_text_view);
        textView.setExpanded(!textView.isExpanded());
        textView.requestLayout(); // 重新布局以更新高度
    }
});
