如何在Android Studio中将按钮扩展为2列？

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:layout_weight="1">

        <Button
            android:id="@+id/button1"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="Button 1"/>
    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:layout_weight="1">

        <Button
            android:id="@+id/button2"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="Button 2"/>
    </LinearLayout>
</LinearLayout>

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

RecyclerView recyclerView = findViewById(R.id.recyclerView);
GridLayoutManager layoutManager = new GridLayoutManager(this, 2); // 2表示两列
recyclerView.setLayoutManager(layoutManager);

// 假设你有一个按钮列表
List<ButtonData> buttonList = ...;
ButtonAdapter adapter = new ButtonAdapter(buttonList);
recyclerView.setAdapter(adapter);
