如何使我的自定义微调器像默认微调器？

Question

So, i have a data which is from my table so i'm using adapter. Here is how i set it up in my adapter

public View getView(int position, View convertView, ViewGroup parent) {
    inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    View row = inflater.inflate(R.layout.list_item, parent,false);
    // get your views here and set values to them

    TextView ItemCodetextview = (TextView) row.findViewById(R.id.itemcode);
    TextView ItemNametextview = (TextView) row.findViewById(R.id.itemname);

    GenerateItemdoModel current = dataModels.get(position);

    ItemCodetextview.setText(current.getItemCode());
    ItemNametextview.setText(current.getItemName());

    return row;
}

list_item

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"

Answer 1

Use this in you spinner

style="@android:style/Widget.Holo.Light.Spinner"

Reference : https://developer.android.com/guide/topics/ui/look-and-feel/themes.html

(or)

use this

Adding a small attribute as android:spinnerMode="dialog"

Answer 2

In list_item.xml :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:paddingTop="10dp"
    android:paddingBottom="10dp"
    android:paddingLeft="5dp"
    android:layout_height="wrap_content">

Add padding in main layout in item layout.
