배열리소스(string-array)를 활용한 GridView

가변적이지 않은 목록을 여지껏 노가다(?) xml로 배치해 오다가 이제야 방법을 알아 냈다.

문득 GridLayout을 쓰면 어떨까 해서 확인해 보니...GridView를 활용한 방법이 딱!

[String 내 배열리소스]

<string-array name="area">
    <item>서울</item>
    <item>경기</item>
    <item>인천</item>
    <item>대전</item>
    <item>세종</item>
    <item>충남</item>
    <item>충북</item>
    <item>광주</item>
    <item>전남</item>
    <item>전북</item>
    <item>대구</item>
    <item>경북</item>
    <item>부산</item>
    <item>울산</item>
    <item>경남</item>
    <item>강원</item>
    <item>제주</item>
    <item>해외</item>
</string-array>

[activity_area.xml 원하는 위치에 GridView배치]

<GridView
    android:id="@+id/gridView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:numColumns="4"
    android:verticalSpacing="2dp"
    android:horizontalSpacing="2dp"
    android:gravity="center"/>

[activity_area_layout_item.xml GridView내에 보여지 레이아웃 아이템(난 버튼으로 처리)]

<Button
    style="@style/DefaultLightButton"
    android:id="@+id/btnItem"
    android:layout_width="match_parent"
    android:layout_height="56dp"
    android:background="@drawable/btn_default"
    android:textColor="#ffffffff"
    android:textSize="16sp"
    xmlns:android="http://schemas.android.com/apk/res/android" />

[아답터 소스]

public class AreaActivity extends AppCompatActivity {
    private Toolbar toolbar;
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_area);
 
        GridView gridView = (GridView) findViewById(R.id.gridView);
 
        //String-array를 ArrayList로 변환
        ArrayList<String> items = new ArrayList<String>(Arrays.asList(getResources().getStringArray(R.array.area)));
 
        gridView.setAdapter(new GridAdapter(items));
        
    }
 
    private class GridAdapter extends BaseAdapter {
 
        ArrayList<String> mItems;
        int mCount;
 
        public GridAdapter(ArrayList<String> items) {
 
            mCount = items.size();
 
            mItems = new ArrayList<String>(mCount);
            for (String item : items) {
                String[] parts = item.split(",");
                for (String part : parts) {
                    part.replace(" ", "");
                    mItems.add(part);
                }
            }
        }
 
        @Override
        public int getCount() {
            return mCount;
        }
 
        @Override
        public Object getItem(int position) {
            return mItems.get(position);
        }
 
        @Override
        public long getItemId(int position) {
            return position;
        }
 
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
 
            View view = convertView;
            if (view == null) {
                view = LayoutInflater.from(parent.getContext()).inflate(R.layout.activity_area_layout_item, parent, false);
            }
 
            Button button = (Button) view.findViewById(R.id.btnItem);
            button.setText(mItems.get(position));
            button.setOnClickListener(new View.OnClickListener() {
                @Override
                    public void onClick(View v) {
 
                    // 링크
 
                    }
            });
 
            return view;
        }
    }
}
