在ListView大小更改后获取layout.height

ListView listView = findViewById(R.id.listView);

// 获取ListView的布局参数
ViewGroup.LayoutParams layoutParams = listView.getLayoutParams();

// 获取ListView的高度
int listViewHeight = layoutParams.height;

// 如果ListView的高度是包裹内容的，可以使用measure()方法来测量高度
if (listViewHeight == ViewGroup.LayoutParams.WRAP_CONTENT) {
    int widthMeasureSpec = View.MeasureSpec.makeMeasureSpec(listView.getWidth(), View.MeasureSpec.EXACTLY);
    int heightMeasureSpec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
    listView.measure(widthMeasureSpec, heightMeasureSpec);
    listViewHeight = listView.getMeasuredHeight();
}

// 在ListView大小更改后获取高度
listView.setOnSizeChangedListener(new OnSizeChangedListener() {
    @Override
    public void onSizeChanged(int w, int h, int oldw, int oldh) {
        // 获取ListView的新高度
        int newListViewHeight = listView.getLayoutParams().height;
        
        // 如果ListView的高度是包裹内容的，可以使用measure()方法来测量新高度
        if (newListViewHeight == ViewGroup.LayoutParams.WRAP_CONTENT) {
            int widthMeasureSpec = View.MeasureSpec.makeMeasureSpec(listView.getWidth(), View.MeasureSpec.EXACTLY);
            int heightMeasureSpec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
            listView.measure(widthMeasureSpec, heightMeasureSpec);
            newListViewHeight = listView.getMeasuredHeight();
        }
        
        // 在这里进行相应的操作，比如更新UI或者执行其他逻辑
    }
});
