请按要求生成一份android扫雷代码，要有布局文件和java文件。同时保证第一次点击不会点到雷，有剩余雷数，有计时和历史查询功能。有初级中级，俩个难度

好的，根据您的要求，以下是一份简单的Android扫雷代码，包括布局文件和Java文件。代码提供初级和中级难度，保证第一次点击不会点到雷，有剩余雷数，有计时和历史查询功能。

布局文件 mine_layout.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mine_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white">

    <TextView
        android:id="@+id/tv_mine_count"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Mine: 10"
        android:textColor="@android:color/black"
        android:textSize="20sp"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/tv_time_count"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Time: 0"
        android:textColor="@android:color/black"
        android:textSize="20sp"
        android:textStyle="bold"
        android:layout_toRightOf="@id/tv_mine_count"
        android:layout_marginLeft="20dp" />

    <TextView
        android:id="@+id/tv_history"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="History"
        android:textColor="@android:color/black"
        android:textSize="20sp"
        android:textStyle="bold"
        android:layout_alignParentRight="true" />

    <GridView
        android:id="@+id/grid_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/tv_mine_count"
        android:horizontalSpacing="1dp"
        android:numColumns="10"
        android:verticalSpacing="1dp" />

</RelativeLayout>
