[問題] 設定BaseAdapter返回的view的高
打算讓listview在頁面上只出現7行
每行佔頁面的1/7
請問該怎麼做？
目前自己試過的方法是這樣....
用ListActivity時，會用到BaseAdapter這個東西
裡面有個getView是給底層取得view用的
public View getView(int position, View view, ViewGroup parent)
{
.....
}
在裡面有產生view的方法，是這樣
view=adapterLayoutInflater.inflate(R.layout.calender_week_row, null);
其中
LayoutInflater adapterLayoutInflater = LayoutInflater.from(c);
c是這隻程式的activity
我原本想用這種方式，去修改view的高
ViewGroup.LayoutParams lp =view.getLayoutParams();
lp.height = 50; //某個計算出來的值
view.setLayoutParams(lp);
用這種方法去改已經生成的view沒問題
可是，因為這個listview呼叫getview時
還沒被加到頁面上，所以lp會是null
自己ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams()也不對
會出現ClassCastException
我就投降了.....
