布局，Android-WeatherApp

Question

我是android开发的新手，如果这对您来说不重要，我仍在努力开发一款仍需要尽快完成的应用程序，我的问题很简单，“我将所有内容放入布局中由于功能的缘故，它会覆盖并重复“”，但我不知道如何避免。
至少更改主题对于专家而言是容易的事情。
结果应该是具有用于搜索城市的EditText和用于选择城市的选择按钮。如果我忘记添加任何东西，请告诉我。

如果不希望将Button和EditText放在forecast_item_layout.xml内，为什么？
将Activity_Main.xml更改为此：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.danie.weather.MainActivity">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/forecastRV"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <EditText
        android:id="@+id/searchCity"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/sendBtn"/>

    <Button
        android:id="@+id/sendBtn"
        android:text="Select"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"/>

</RelativeLayout>

和forecast_item_layout.xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/selectableItemBackground"
    android:gravity="center_vertical"
    android:orientation="vertical"
    android:padding="18dp">

    <ImageView
        android:id="@+id/forecastIV"
        android:layout_width="40dp"
        android:layout_height="40dp"
        tools:src="@mipmap/ic_launcher" />

    <TextView
        android:id="@+id/descriptionTV"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="20sp"
        tools:text="Text" />
</LinearLayout>
