如何在安卓编程中通过点击按钮在同一个活动中插入一个完整的LinearLayout？

<LinearLayout
    android:id="@+id/parentLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="点击插入LinearLayout" />

</LinearLayout>

import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.LinearLayout;

public class MainActivity extends AppCompatActivity {

    private LinearLayout parentLayout;
    private Button button;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        parentLayout = findViewById(R.id.parentLayout);
        button = findViewById(R.id.button);

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 创建一个新的LinearLayout
                LinearLayout newLinearLayout = new LinearLayout(MainActivity.this);
                newLinearLayout.setLayoutParams(new LinearLayout.LayoutParams(
                        LinearLayout.LayoutParams.MATCH_PARENT,
                        LinearLayout.LayoutParams.WRAP_CONTENT));
                newLinearLayout.setOrientation(LinearLayout.VERTICAL);

                // 设置新LinearLayout的内容
                // ...

                // 将新LinearLayout添加到父级LinearLayout中
                parentLayout.addView(newLinearLayout);
            }
        });
    }
}
