不管是先add videoView1 還是先add videoView2，先添加的都是在上層覆寫了后添加的
換成ImageView，TextView都是正常的
求怎么解決
uj5u.com熱心網友回復：
1.先回答你的問題：沒有明確指定添加的控制位置和依賴關系。2.提出問題：你可以在layout中先添加好控制元件，然后控制顯示與隱藏
uj5u.com熱心網友回復：
1：我這是RelativeLayout，后添加的不是應該覆寫先添加的嗎，2個ImageView或者2個TextView都是正常的
2：需求是要動態添加，VideoView、ImageView、TextView，數量是不定的
有個List<View>,View的型別是那3種，list大小不定，只有在添加VideoView后接著添加VideoView才會出現問題，
添加VideoView后添加ImageView，再添加VideoView都是正常的
