나는 동적 인 목록보기를 구현해야합니다. 저는 이미 배열과 정적 인 방법으로 그것을 만들었지 만, 그리드에 새 요소를 만들고 listner를 클릭하는 버튼을 추가해야합니다. 배열에서 목록으로 전환하면 해결할 수 있습니까? 여기 내 코드입니다, 아무도 조금 도와주세요 줄래?dinamic 목록보기에 요소 추가
GRID보기 :
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:horizontalSpacing="-10dp"
tools:context="com.example.giovanni.mainapp_drawer.Activities.MainActivity"
android:orientation="vertical"
android:columnWidth="160dp"
android:fadeScrollbars="true"
android:gravity="center"
android:numColumns="2"
android:stretchMode="columnWidth"
android:id="@+id/gv"
</GridView>
버튼 어댑터 :
public class RoomsBtnAdapter extends BaseAdapter{
private Context context;
private final String[] strings;
private final int[] colors;
public RoomsBtnAdapter(Context context, String[] strings, int[] colors) {
this.context = context;
this.strings = strings;
this.colors = colors;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View gridView;
if (convertView == null) {
gridView = new View(context);
gridView = inflater.inflate(R.layout.room_btn, null);
Button btn = (Button) gridView.findViewById(R.id.roomBtn);
btn.setText(strings[position]);
btn.setBackgroundResource(colors[position]);
} else {
gridView = (View) convertView;

return gridView;
