将 android:layout_alignParentRight="true" 分配给 AutoCompleteTextView :

 <AutoCompleteTextView
            android:id="@+id/item_autoComplete"
            android:layout_width="150dp"
            android:layout_height="wrap_content"
            android:layout_alignBaseline="@+id/textView1"
            android:textCursorDrawable="@null"
            android:background="@drawable/background_textfield"
            android:singleLine="true"
            android:layout_marginRight="10dp"
            android:layout_alignParentRight="true"
            android:paddingLeft="2dp"
            android:textColor="#000000" />
        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            android:layout_marginRight="38dp"
            android:layout_marginTop="84dp"
            android:text="chooseStation"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="#d70261" />
