因为我当前的Activity中只有一个EditText能获取到焦点，所以当点击输入法右下角的next时，EditText的右边(或下方)控件不能获取焦点，所以就出现了上述错误。

解决办法

把EditText的android:imeOptions="actionNone" 即可，如下：

<EditText                android:id="@id/et_search"                android:layout_width="wrap_content"                android:layout_height="30dp"                android:layout_centerVertical="true"                android:layout_marginLeft="5dp"                android:layout_toLeftOf="@id/iv_search_delete"                android:layout_toRightOf="@id/iv_sc"                android:background="@null"                android:hint="@string/search_tips"                android:singleLine="true"                android:textColorHint="@color/light_gray"                android:textSize="@dimen/fontsize_14"                 android:imeOptions="actionNone"/>
