Android以编程方式添加两个带有画布的视图

public class CustomView extends View {
    // 构造方法
    public CustomView(Context context) {
        super(context);
    }

    // 重写onDraw方法
    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        // 在canvas上进行绘制操作
        // ...
    }
}

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 创建两个CustomView对象
        CustomView customView1 = new CustomView(this);
        CustomView customView2 = new CustomView(this);

        // 获取布局容器
        LinearLayout layout = findViewById(R.id.layout);

        // 将CustomView对象添加到布局中
        layout.addView(customView1);
        layout.addView(customView2);
    }
}

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