我在活動中創建了片段。每個片段都有一個文本視圖。我想讓片段內的所有文本視圖都可以滾動。下面是我的 xml 和 java 代碼。提前致謝
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".chemistry.AtomicNumber">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@ id/atomicNumberDefinition"
android:text="The atomic number..... "
android:textAlignment="center"
android:textColor="#000000"
android:textSize="24sp"
android:scrollbars="vertical"
/>
Java Code:
public class AtomicNumber extends Fragment {
private static final String ARG_PARAM1 = "param1";
private static final String ARG_PARAM2 = "param2";
private String mParam1;
private String mParam2;
public AtomicNumber() {
}
public static AtomicNumber newInstance(String param1, String param2) {
AtomicNumber fragment = new AtomicNumber();
Bundle args = new Bundle();
args.putString(ARG_PARAM1, param1);
args.putString(ARG_PARAM2, param2);
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
mParam1 = getArguments().getString(ARG_PARAM1);
mParam2 = getArguments().getString(ARG_PARAM2);
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_atomic_number, container, false);
}
}
請讓我知道如何在 java 檔案中撰寫正確的代碼。

我建議使用ScrollView:
<ScrollView
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:orientation="vertical">
<TextView
android:id="@ id/atomicNumberDefinition"
android:text="The atomic number..... "
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000000"
android:textSize="24sp" />
</ScrollView>

您可以使用ScrollView或NestedScrollView。RecycleView如果您需要滾動串列項,則可以使用旁邊。
