Ustawiam arrayList na 12 pozycji, jednak arrayAdapter zwraca tylko jeden element na ekranie, dlaczego tak jest? Ma pokazywać 12 pozycji na liście.arrayAdapter zwraca tylko jedną pozycję, Android
public class MainActivity extends Activity {
ArrayList<CheckBoxInfo> cfo = new ArrayList<CheckBoxInfo>();
CheckBoxInfo cbr;
private ListAdapter MyAdapter;
ListView listview;
MyAdapter myAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
cbr = new CheckBoxInfo();
cbr.checkBoxName = "dfdjklfjdkljf";
cbr.checkBoxState = true;
for(int i = 0; i <12; i++){
cfo.add(cbr);
}
Toast.makeText(MainActivity.this, "size: " + cfo.size(), Toast.LENGTH_SHORT).show();
listview = (ListView) findViewById(R.id.listView);
myAdapter = new MyAdapter(cfo, this);
listview.setAdapter(myAdapter);
}
public class MyAdapter extends ArrayAdapter<CheckBoxInfo> {
private List<CheckBoxInfo> checkBoxList;
private Context context;
public MyAdapter(List<CheckBoxInfo> infoList, Context context) {
super(context, R.layout.row_layout, infoList);
this.checkBoxList = infoList;
this.context = context;
}
public View getView(int position, View convertView, ViewGroup parent) {
// First let's verify the convertView is not null
if (convertView == null) {
// This a new view we inflate the new layout
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.row_layout, parent, false);
}
// Now we can fill the layout with the right values
TextView tv = (TextView) convertView.findViewById(R.id.textView1);
CheckBox cb = (CheckBox) convertView.findViewById(R.id.checkBox1);
CheckBoxInfo cbi = checkBoxList.get(position);
Toast.makeText(MainActivity.this, "position: " + position, Toast.LENGTH_SHORT).show();
tv.setText(cbi.checkBoxName);
return convertView;
}
} // end MyAdapter
}
row_layout.xml
