滾動只用兩個手指

林製造具有滾動圖的佈局工作，它有一個佈局中實現多次。的問題是，當我在我的設備上運行，滾動只有當我用一個手指按住它，並刷卡作品的另一個滾動只用兩個手指

我已經搜索了這個問題，但我仍然沒有答案

這麼多的嵌套導航抽屜的主要主？你知道每個嵌套的findViewById（）成本嗎？ –

是的，但這不是結束，是填補每一個佈局與外部數據..和一些佈局agrupped因爲他們possibily需要被牆根 –

除此之外，還有與match_parent和WRAP_CONTENT幾個問題。如果你的父母已經'wrap_content'的高度或寬度，則孩子必須永遠不會有'match_parent'的高度或寬度分別 –

它有一個愚蠢的解決方案！

我們只需要簡單地替換父CoordinatorLayout與佈局NestedScrollView
