Question

我制作了2个集成微调器（每个类别的第一个微调器，每个类别的“值”第二个微调器），就像中一样。

我希望从第二个微调器中选择的“值”能够与EditText（数字）连接，以得到“值”的名称+“值”的总和，当按下“ TAMBAH”按钮时，该值将显示在ListView上。将listview归档后，“ SIMPAN”按钮会将数据从ListView保存到下一个活动。

从第二个微调器中选择的值+从EditText中的总数（数字）+“ TAMBAH”按钮=数据将从下面的列表视图中保存。

我的strings.xml

<resources>
<string-array name="kategori">
        <item>TANAMAN BORDIR</item>
        <item>TANAMAN LATAR</item>
        <item>TANAMAN PELINDUNG</item>
        <item>TANAMAN PEMANIS</item>
        <item>LAINNYA</item>
    </string-array>

    <string-array name="tn_bordir">
        <item>Aglonema</item>
        <item>Amarastus</item>
        <item>Ararea</item>
    </string-array>

    <string-array name="tn_latar">
        <item>Aneka Kamboja</item>
        <item>Bonsai Anting Putri</item>
        <item>Bonsai Beringin Korea</item>
    </string-array>

    <string-array name="tn_pelindung">
    <item>Angsana</item>
    <item>Bambu Jepang</item>

    </string-array>

    <string-array name="lainnya">

    </string-array>
</resources>

微调器ArrayList + EditText组合要保存在ListView中吗？
