<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <ListView
        android:id="@+id/listview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <LinearLayout
        android:id="@+id/transparent_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:background="@android:color/transparent"
        android:clickable="true"
        android:focusable="true" />

</RelativeLayout>

public class MainActivity extends AppCompatActivity {

    private ListView listView;
    private LinearLayout transparentLayout;

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

        listView = findViewById(R.id.listview);
        transparentLayout = findViewById(R.id.transparent_layout);

        // 设置ListView的数据
        // ...

        // 设置透明LinearLayout的点击事件监听器
        transparentLayout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 在此处处理点击事件，例如展开/折叠ListView
                if (listView.getVisibility() == View.VISIBLE) {
                    listView.setVisibility(View.GONE);
                } else {
                    listView.setVisibility(View.VISIBLE);
                }
            }
        });
    }
