kotlin recyclerviewについて

RecyclerViewでRoomのデータを一覧表示しようとしています。一覧にはなっているようですが、見切れており、全部表示させるようにしたいです。

kotlin
1class CustomAdapter(private val reportsList: List<Reports>): RecyclerView.Adapter<CustomAdapter.ViewHolder>() {
2
3    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
4        val view = LayoutInflater.from(parent.context).inflate(R.layout.list, parent, false)
5        return ViewHolder(view)
6    }
7
8    override fun onBindViewHolder(holder: CustomAdapter.ViewHolder, position: Int) {
9        val reports = reportsList[position]
10
11        holder.name.text = reports.title
12        holder.body.text = reports.impressions
13    }
14
15    override fun getItemCount(): Int = reportsList.size
16
17    class ViewHolder(view: View): RecyclerView.ViewHolder(view){
18
19        val name: TextView
20        val body: TextView
21
22        init {
23            name = view.findViewById(R.id.name)
24            body = view.findViewById(R.id.body)
25        }
26    }
27}

xml
1<ScrollView
2    xmlns:android="http://schemas.android.com/apk/res/android"
3    xmlns:app="http://schemas.android.com/apk/res-auto"
4    android:layout_width="match_parent"
5    android:layout_height="match_parent"
6    android:id="@+id/scrollView"
7    android:isScrollContainer="false">
8
9    <LinearLayout
10        android:layout_width="match_parent"
11        android:layout_height="wrap_content"
12        android:id="@+id/linearLayout">
13
14        <LinearLayout
15            android:layout_width="0dp"
16            android:layout_height="wrap_content"
17            android:layout_weight="1"
18            android:orientation="vertical"
19            android:layout_marginStart="16dp">
20
21        <TextView
22            android:layout_width="wrap_content"
23            android:layout_height="wrap_content"
24            android:id="@+id/name"
25            android:textStyle="bold"/>
26        <TextView
27            android:layout_width="wrap_content"
28            android:layout_height="wrap_content"
29            android:id="@+id/body"/>
30        <Button
31            android:layout_width="wrap_content"
32            android:layout_height="wrap_content"
33            android:text="戻る"
34            android:id="@+id/backBtn"/>
35
36        </LinearLayout>
37
38
39    </LinearLayout>
40
41</ScrollView>

Activity側のコードは以下です。

kotlin
1class SentMailListActivity : AppCompatActivity() {
2
3    private lateinit var binding : ActivitySentMailListBinding
4    private val viewModel: ReportsViewModel by viewModels()
5    lateinit var mAdapter: CustomAdapter
6
7    override fun onCreate(savedInstanceState: Bundle?) {
8        super.onCreate(savedInstanceState)
9        binding = ActivitySentMailListBinding.inflate(layoutInflater)
10        setContentView(binding.root)
11
12        // RecyclerViewの取得
13        //https://hirauchi-genta.com/kotlin-recyclerview/
14        val recyclerView = binding.recyclerView
15
16        val dividerItemDecoration = DividerItemDecoration(this, LinearLayoutManager(this).orientation)
17        recyclerView.addItemDecoration(dividerItemDecoration)
18
19        // LayoutManagerの設定
20        recyclerView.layoutManager = LinearLayoutManager(this)
21
22        // CustomAdapterの生成と設定
23        mAdapter = CustomAdapter(viewModel.reportsData)
24        recyclerView.adapter = mAdapter
25    }
26}

xml
1<LinearLayout
2    xmlns:android="http://schemas.android.com/apk/res/android"
3    android:id="@+id/container"
4    android:layout_width="match_parent"
5    android:layout_height="match_parent">
6
7    <androidx.recyclerview.widget.RecyclerView
8        android:id="@+id/recycler_view"
9        android:layout_width="match_parent"
10        android:layout_height="wrap_content"/>
11</LinearLayout>
