在android中以编程方式创建多个ListViews

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

// MainActivity.java
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.LinearLayout;
import android.widget.ListView;
import androidx.appcompat.app.AppCompatActivity;
import java.util.ArrayList;
import java.util.List;

public class MainActivity extends AppCompatActivity {

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

        LinearLayout container = findViewById(R.id.container);

        // 创建第一个ListView
        ListView listView1 = new ListView(this);
        List<String> data1 = new ArrayList<>();
        data1.add("Item 1");
        data1.add("Item 2");
        data1.add("Item 3");
        ArrayAdapter<String> adapter1 = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, data1);
        listView1.setAdapter(adapter1);
        container.addView(listView1);

        // 创建第二个ListView
        ListView listView2 = new ListView(this);
        List<String> data2 = new ArrayList<>();
        data2.add("Item A");
        data2.add("Item B");
        data2.add("Item C");
        ArrayAdapter<String> adapter2 = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, data2);
        listView2.setAdapter(adapter2);
        container.addView(listView2);
    }
}
