Question

我有一个带有折叠工具栏的活动，除了通过菜单项和后退箭头按钮触摸事件外，一切正常。

如果工具栏（android.support.v7.widget.Toolbar）放在CollapsingTollbarLayout外面，一切正常。

据我所知，折叠是从工具栏中抓取触摸事件而无法到达，对吧？我试过requestDisallowInterceptTouchEvent设置为false，但没有运气。

像这样：

mToolbar.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                v.getParent().requestDisallowInterceptTouchEvent(false);
                return false;
            }
        });

请帮助我理解我错过了什么。非常感谢！

这是我的布局：

            return true;
        case R.id.delete_big_goal:
            try {
                IntentionDAOHelper.deleteIntention(mBigGoal, mBigGoalsDAO);
            } catch (SQLException e) {
                e.printStackTrace();
            }
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

我已在此处添加了另一个工具栏来解决此问题：

        <android.support.design.widget.FloatingActionButton
        android:id="@+id/add_sub_goal_btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="16dp"
        android:src="@drawable/ic_plus_fab"
        app:borderWidth="0dp"
        app:layout_anchor="@id/sub_goals_list_container"
        app:layout_anchorGravity="bottom|left|end" />

    <android.support.v7.widget.Toolbar
        android:id="@+id/sub_goals_list_toolbar_uncollapse"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        />

</android.support.design.widget.CoordinatorLayout>

我敢打赌这不是最好的方式（远离它），但它运作良好。

在CollapsingTollbarLayout（AppBarLayout）中菜单项不响应
