if I understood you right you should use the following code within your first layout

如果我理解正确，您应该在第一个布局中使用以下代码

<include 
     layout="@layout/second_layout"
     android:id="@+id/includedLayout"
     android:visibility="gone"
     android:layout_below="@id/buttonId" />

and then in your button's action you just use

然后在您的按钮操作中，您只需使用

((RelativeLayout)findViewById(R.id.includedLayout)).setVisibility(View.VISIBLE);

    LinearLayout placeHolder = (LinearLayout) findViewByid(R.id.layout);
    getLayoutInflater().inflate(R.layout.second_layout, placeHolder);

Use include

用 include

Here is a somewhat fuller example. The square blue layout is inserted into the main layout using include.

这是一个更完整的例子。使用 将方形蓝色布局插入到主布局中include。

activity_main.xml

活动_main.xml

This is the main layout. The custom layout is referenced using include. You can override any of the attributes here, too.

这是主要布局。使用 引用自定义布局include。您也可以在此处覆盖任何属性。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="16dp">

    <!-- Here is the inserted layout -->
    <include layout="@layout/my_layout"/>

</RelativeLayout>

my_layout.xml

my_layout.xml

This is the custom layout that will be inserted into the main layout.

这是将插入到主布局中的自定义布局。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:background="@color/colorPrimary">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:padding="5dp"
        android:text="My Layout"/>

</RelativeLayout>

You Should use this code snippet to add a Layout inside another one.

您应该使用此代码片段在另一个中添加一个布局。

    parentLayout=(LinearLayout)findViewById(R.id.parentLayout);
    inflateView=View.inflate(this,R.layout.view_video,parentLayout);

Here the parentLayoutis the root View and R.layout.view_videois the layout that you need to insert.

这里parentLayout是根视图，R.layout.view_video是您需要插入的布局。

Use LayoutInflator to inflate an external layout into existing layout. Checkout LayoutInflateron Android Dev Site for more information about it.

使用 LayoutInflator 将外部布局膨胀到现有布局中。查看Android Dev Site 上的LayoutInflater了解更多信息。
