[英]ScrollView inside recycler view item is not scrolling
我有 MetarialCardView,它在 RecyclerView 的列表項中有一定的高度,我在這個 MetarialCardView 中有一個 scrollView。 我想通過在 ScrollView 中放置一個長文本來滾動,但它沒有滾動。 除了通常的 MaterialCardView 是可點擊的,但是對於 scrollView,它也失去了可點擊性。
感謝您提供的任何幫助。
<com.google.android.material.card.MaterialCardView
android:layout_width="match_parent"
android:layout_height="130dp"
app:cardCornerRadius="12dp"
app:strokeColor="@color/primary_text_color_50"
app:strokeWidth="0.5dp">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.constraintlayout.widget.ConstraintLayout
android:id="@+id/clContract"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="@+id/ivCompleted"
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_marginTop="12dp"
android:layout_marginEnd="8dp"
android:src="@drawable/ic_completed"
android:visibility="visible"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="@+id/tvContract"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="12dp"
android:layout_marginTop="12dp"
android:layout_marginEnd="8dp"
android:fontFamily="@font/gotham_rounded_bold"
android:textColor="@color/primary_text_color"
android:textSize="@dimen/text_12"
app:layout_constraintEnd_toStartOf="@+id/ivCompleted"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
tools:text="Agreement" />
</androidx.constraintlayout.widget.ConstraintLayout>
</ScrollView>
<View
android:id="@+id/viewGradient"
android:layout_width="match_parent"
android:layout_height="30dp"
android:layout_gravity="bottom"
android:background="@drawable/shape_gradient_bottom_separator" />
</com.google.android.material.card.MaterialCardView>
嘗試在 xml 中使用 NestedScrollview 而不是 ScrollView 並在 java 文件中使用以下代碼
recyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
int action = e.getAction();
switch (action) {
case MotionEvent.ACTION_MOVE:
rv.getParent().requestDisallowInterceptTouchEvent(true);
break;
}
return false;
}
@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
}
@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}
});
試試這個。 如果你想滾動它只是把它放在滾動視圖中,我也從滾動視圖中刪除了圖標。
對於點擊,我認為您可以在itemView上設置點擊監聽器,或者只是將 id 提供給 cardview 並在其上設置點擊監聽器。
