Android - gridview显示重复值（两次）
我有一个应用程序，我想用textview和imageview显示gridview ....
这个gridview必须根据点击的按钮更改它的值，即单击abc按钮然后gridview应该只显示该特定的名称和图像然后如果我点击xyz按钮那么只有数据但是现在我正在获取数据两个
我已经完成了
mAdapter = new GridviewAdapter(this, listCountry, listFlag);
// Set custom adapter to gridview
gridView = (GridView) findViewById(R.id.gridview_t);
gridView.setBackgroundColor(Color.WHITE);
gridView.setAdapter(mAdapter);
public void get_record()
{
try {
db = openOrCreateDatabase("dbname",
SQLiteDatabase.CREATE_IF_NECESSARY, null);
db.setVersion(1);
db.setLocale(Locale.getDefault());
db.setLockingEnabled(true);
cur_BeansLegumesn = db.rawQuery(
"select name,image from "+ Table_name +" order by name", null);
System.out.println("connected this i sdone");
array_BeansLegumes = new String[cur_BeansLegumesn.getCount()];
int i = 0, j = 0;
list = new ArrayList<String>();
img_list = new ArrayList<String>();
if (cur_BeansLegumesn.moveToFirst()) {
do {
int contentTitleColumn = cur_BeansLegumesn
.getColumnIndex("name");
int img = cur_BeansLegumesn.getColumnIndex("image");
str = cur_BeansLegumesn.getString(contentTitleColumn)
.toString();
str1 = cur_BeansLegumesn.getString(img).toString();
// array_BeansLegumes[i]=str;
// array_BeansLegumes_imgname[i]=str1;
list.add(str);
img_list.add(str1);
System.out.println(str);
// System.out.println("this is img " + str1);
i++;
} while (cur_BeansLegumesn.moveToNext());
}
cur_BeansLegumesn.close();
} catch (Exception e) {
System.out.println("error " + e + "");
} finally {
db.close();
}
这将填充适配器
public void prepareList() {
listCountry.addAll(list);
for (int i = 0; i < list.size(); i++) {
//System.out.println("this is prepa... " + listCountry.get(i));
}
listFlag = new ArrayList<Integer>();
listimgname = new ArrayList<String>();
listimgname.removeAll(img_list);
listimgname.addAll(img_list);
for (int j = 0; j < img_list.size(); j++) {
System.out.println("img name " + listimgname.get(j));
int id = getResources().getIdentifier(listimgname.get(j),
"drawable", getPackageName());
listFlag.add(id);
}
mAdapter = new GridviewAdapter(this, listCountry, listFlag);
gridView = (GridView) findViewById(R.id.gridview_t);
gridView.setBackgroundColor(Color.WHITE);
gridView.setAdapter(mAdapter);
}
这是我的适配器类
public class GridviewAdapter extends BaseAdapter
{
private ArrayList<String> listCountry;
private ArrayList<Integer> listFlag;
private Activity activity;
public GridviewAdapter(Activity activity, ArrayList<String> listCountry,
ArrayList<Integer> listFlag) {
super();
// this.listCountry = listCountry;
this.listCountry = new ArrayList<String>();
this.listCountry=listCountry;
this.listFlag = listFlag;
this.activity = activity;
System.out.println("this is contry name "+this.listCountry);
System.out.println("this is img name "+this.listFlag);
//System.out.println();
}
@Override
public int getCount() {
// TODO Auto-generated method stub
System.out.println("len " + listCountry.size());
return listCountry.size();
}
@Override
public String getItem(int position) {
// TODO Auto-generated method stub
return listCountry.get(position);
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
public static class ViewHolder {
public ImageView imgViewFlag;
public TextView txtViewTitle;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ViewHolder view;
LayoutInflater inflator = activity.getLayoutInflater();
if (convertView == null) {
view = new ViewHolder();
convertView = inflator.inflate(R.layout.test, null);
view.txtViewTitle = (TextView) convertView
.findViewById(R.id.grid_item_label);
view.txtViewTitle.setTextColor(Color.BLACK);
view.imgViewFlag = (ImageView) convertView
.findViewById(R.id.grid_item_image);
view.imgViewFlag.setBackgroundResource(R.drawable.view_default);
convertView.setTag(view);
} else {
view = (ViewHolder) convertView.getTag();
}
try {
view.txtViewTitle.setText(listCountry.get(position));
view.imgViewFlag.setImageResource(listFlag.get(position));
} catch (Exception e) {
System.out.println("this is error " + e.getMessage());
}
return convertView;
}
}
数据来自DB，而gree imges表示我点击了xyz btn并且它也必须显示img但是没有显示
这是我的log-cat
