的Android線性佈局與動畫

我實現此作爲延伸的LinearLayout自定義視圖的要求，所述的LinearLayout包含兩個以上LinearLayouts（每行），並且每個元件是延伸的RelativeLayout的幷包含用於動畫/狀態變化的功能的另一自定義視圖。

我遇到的問題是..因爲動畫長大的圓圈箭頭縮放的ImageView的ImageView的是由其父容器裁剪，因爲大小設置一次繪製。我可以在父自稱setScaleX/Y縮放ImageView的前..但後來我得到一些怪異的行爲......必須有一個簡單的解決方案！

使用setClipChildren(false)在ViewGroup爲RelativeLayout或LinearLayout其中ImageView包含英寸

嘗試這樣做在像了層次結構的佈局的每一層被..與視圖的大小做被設置一次繪製不管動畫 – Arjun

我一直使用這個很長一段時間，它的工作很棒。如果您使用xml發佈代碼，那麼我們只能進一步挖掘。 –

我已經添加了上面的代碼 – Arjun
