我正在使用協調器佈局和NestedScrollView在我的片段中用於摺疊工具欄動畫。我將視圖動態添加到我的嵌套滾動視圖容器。我已經在NestedScrollView中的視圖上實現了onClickListener,但任何視圖的第一次點擊總是被忽略。當我第二次點擊或超過它的作品。我的XML代碼如下:Android NestedScrollView的子視圖忽略第一次點擊

好像NestedScrollView被攔截的觸摸事件,而不是傳遞給孩子的第一次。 我該如何解決這個問題?
您是否嘗試過擴展'AppBarLayoutBehavior'並覆蓋onInterceptTouchEvent並就不應觸發嵌套滾動的'target'意見'返回FALSE',所以他們可以消耗事件而不觸發嵌套滾動? –
@NikolaDespotoski我將視圖動態地添加到NestedScrollView,所以我不知道它是否會工作。 我試圖添加一個自定義應用程序:layout_behavior,但它給了我一個例外:java.lang.RuntimeException:無法膨脹行爲子類。 你能舉一些你想說的話嗎? –
明白了。該問題是由於Android支持庫(23.0.1)NestedScrollView中的錯誤。它可以在這裏找到:https://code.google.com/p/android/issues/detail?id=178041 這個問題很可能會在下一個版本中修復。直到那麼你可以看到這個帖子的解決方法:http://stackoverflow.com/a/32783524/1999153 –
