GridView中的多个TextView选择

Question

我设法创建了一个TextView网格，其中包含所选数字的预览。从代码中可以看出，按下一个数字就会出现一个简单的吐司。我需要做多个数字选择，并可能创建一个数组以推迟到另一个活动。你能帮帮我吗？

XML：

<LinearLayout
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:orientation="vertical"
    android:padding="10dp"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:background="@drawable/zaffiro">

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:layout_gravity="center" >

        <GridView
            tools:context=".MainActivity"
            xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:tools="http://schemas.android.com/tools"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:columnWidth="10dp"
            android:numColumns="6"
            android:verticalSpacing="2dp"
            android:stretchMode="columnWidth"
            android:gravity="center"
            android:id="@+id/gridview" />
    </LinearLayout>

    <LinearLayout
        android:orientation="horizontal"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp"
        >

        <Button
            android:layout_margin="10dp"
            android:layout_weight="1"
            android:layout_width="100dp"
            android:layout_height="40dp"
            android:text="Importo"
            android:textColor="#fff"
            android:background="@drawable/gioca_pressed"/>

        <Button
            android:layout_margin="10dp"
            android:layout_weight="1"
            android:layout_width="100dp"
            android:layout_height="40dp"
            android:text="Annulla"
            android:textColor="#fff"
            android:background="@drawable/annulla_pressed"/>

    </LinearLayout>

</LinearLayout>
