[Android] 解決ListView在scroll時會變黑的問題

使用ListView時,若有更改過他的layout,


如我自己把它的背景顏色改為自己定義的color/bgColor

當執行這個APP時,若果這個ListView中的child很多
就需要拖拉(scroll)畫面才能看到其他的內容

問題就在於這個scroll動作,
在拖拉這個ListView時,會發現拖拉的過程它會變成一坨黑
感覺是buffer的問題

解決的方法在SDK blog上有提到,
只要在Layout中加入一句 android:cacheColorHint="#00000000"
剛剛的Layout xml更改後變為


便可以解決這問題了。
