每次我在ViewPager中滑动到新屏幕时,如果整个视图长于设备屏幕,它就会向下滚动。
我希望视图寻呼机从顶部开始。我尝试使用其他东西...
android:focusable="true"
android:focusableInTouchMode="true"
在editText周围的布局中,但实际上我什至不知道焦点在哪里。
我还尝试了不同的布局:
android:descendantFocusability="blocksDescendants"
我什至不确定焦点在哪里。
这是我的片段xml:

将layout_Margin更改为padding,并且由于某种原因解决了问题。向任何可以解释原因的人提供支持。
旧:
<android.support.constraint.ConstraintLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:focusable="true"
android:focusableInTouchMode="true"
android:layout_margin="20sp">
新
:<android.support.constraint.ConstraintLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:focusable="true"
android:focusableInTouchMode="true"
android:padding="20dp">
