请检查以下答案，我已添加 LinearLayout 和 weightSum 以保持

它喜欢 EditText - ＆gt;按钮 - ＆gt;按钮

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <LinearLayout
        android:id="@+id/mainGrid"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:weightSum="5" >

        <ListView
            android:id="@+id/itemListView"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="3"
            android:padding="5dp" />

        <TextView
            android:id="@+id/Instructions"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_gravity="center"
            android:layout_weight="0.7"
            android:gravity="start|left"
            android:padding="5dp"
            android:singleLine="false"
            android:text="Enter details of item to add to you timer list below. Enter the times in seconds. The finish by refers to if you need an item to finish before the end, again in seconds." />

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1.3"
            android:orientation="horizontal"
            android:weightSum="2" >

            <LinearLayout

                    android:ems="10"
                    android:hint="Item to add"
                    android:inputType="textPersonName" />
