如何將兩個文字瀏覽添加到可擴展列表視圖的子項

Question

我想在可擴展列表視圖中並排放置兩個文字瀏覽。不幸的是，堆棧溢出和Google搜索中發現的所有解決方案都是徒勞的。

這個鏈接看起來相似，但顯然不是解決 adding two textViews to the header of the expandable listview

我要的是將兩個文本的意見對孩子不擴展列表的標題。

的我多麼希望這兩份案文的觀點，看起來像在子視圖

Answer 1

這可能會有幫助。以編程方式創建相對佈局，將文本視圖添加到相對佈局並將相對佈局添加到預期視圖。

類似這樣的： RelativeLayout relativeLayout = new RelativeLayout（this）; RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams（width，RelativeLayout.LayoutParams.WRAP_CONTENT）;

parentView .addView（RelativeLayout的）;
