eidtText appears white border bar on Xiaomi mobile phone, but it doesn't appear on Huawei Samsung and other mobile phones. It specially records the problem of adaptation

The white border appears directly in the search section to view the code

<RelativeLayout
        android:id="@+id/et_search_root"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="25dp"
        android:layout_weight="1"
        android:background="@drawable/shape_search_head_bg"
        android:orientation="horizontal">

        <EditText
            android:id="@+id/et_search"
            android:layout_toLeftOf="@+id/iv_search_delete"
            android:layout_width="match_parent"
            android:layout_height="35dp"
            android:gravity="center_vertical"
            android:background="@color/transparent"
            android:drawableLeft="@drawable/search_white"
            android:drawablePadding="7dp"
            android:textColorHint="@color/skin_search_font_color"
            android:imeOptions="actionSearch"
            android:paddingLeft="10dp"
            android:maxLines="1"
            android:singleLine="true"
            android:maxLength="15"
            android:ellipsize="end"
            android:textSize="15dp"
            tools:text=""
            android:textColor="@color/skin_common_title"/>

        <LinearLayout
            android:id="@+id/iv_search_delete"
            android:layout_alignParentRight="true"
            android:layout_width="35dp"
            android:layout_height="35dp"
            android:orientation="vertical"
            android:gravity="center"
            android:visibility="gone"
            tools:visibility="visible">

            <ImageView
                android:layout_width="19.2dp"
                android:layout_height="19.2dp"
                android:background="@drawable/search_delete"/>

        </LinearLayout>


    </RelativeLayout>

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">

    <solid android:color="@color/account_line_color" />

    <corners
        android:radius="4dp"/>
</shape>

Reference adaptation: EditText background is shown in black on some mobile phones

Found that transparent properties need to be set on Xiaomi mobile phone

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <stroke android:width="1dp" android:color="@color/transparent" />
    <solid android:color="@color/account_line_color" />

    <corners
        android:radius="4dp"/>
</shape>

The final solution is:

In some mobile phones, there are inexplicably white borders or black background colors, which need to be displayed in different attributes such as
It's good that the direct colors such as stroke and solid become transparent. Specific reasons need to be studied!
