如何在android studio中动态创建framelayout中的framelayout？

<FrameLayout
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</FrameLayout>

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

FrameLayout childFrameLayout = new FrameLayout(this);
childFrameLayout.setLayoutParams(new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT));

childFrameLayout.setBackgroundColor(Color.BLUE);
childFrameLayout.setPadding(16, 16, 16, 16);

container.addView(childFrameLayout);

TextView textView = new TextView(this);
textView.setText("Dynamic View");
childFrameLayout.addView(textView);
