如何在android中设置另一个布局内的布局全底

<RelativeLayout
    android:id="@+id/outer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- 其他布局元素 -->

    <LinearLayout
        android:id="@+id/inner_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true">

        <!-- 内层布局元素 -->

    </LinearLayout>

</RelativeLayout>

RelativeLayout outerLayout = findViewById(R.id.outer_layout);
LinearLayout innerLayout = findViewById(R.id.inner_layout);

RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
    RelativeLayout.LayoutParams.MATCH_PARENT,
    RelativeLayout.LayoutParams.WRAP_CONTENT
);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
innerLayout.setLayoutParams(layoutParams);

outerLayout.addView(innerLayout);
