OnClickListener在Android视图中不使用嵌套元素

Question

所以我有一些嵌套布局的视图，我希望能够点击@ + id / likeStar imageview。我知道我的OnClickListener是正确的，因为它一直工作，直到我开始添加嵌套布局。我需要更改什么才能再次点击ImageView？

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_height="wrap_content"
    android:descendantFocusability="blocksDescendants"

    android:paddingBottom="8dp"
    android:paddingTop="8dp" >

    <!-- Title -->

    <LinearLayout

Answer 1

如果它确实是片段活动或活动，则更改以下行

like = ((ImageView) view.findViewById(R.id.likeStar));

到

like = ((ImageView) findViewById(R.id.likeStar));

Answer 2

我认为问题不在您的布局中。我假设这个布局作为listview中的项目并且使用了dataadapter，在getView方法中你使用onClick on inflated view来窃取来自children的MotionEvent。处理单击的两种方法 - 使用onTouchEvent或更简单的方法是使用listview提供的onItemClick事件。

Answer 3

请你试试getCardContent(Context context)。 view.invalidate(); return view;
