列表视图无线电组错误 [英] listview with radio group error
本文介绍了列表视图无线电组错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
大家我创建一个自定义列表视图动态单选按钮添加到RadioGroup中高达，我得到我想要什么，但是当我尝试选择在第一排一个单选按钮，然后在第5，第9个自动第一个按钮，13行是越来越选择当我选择第二行中的任何按钮，然后在第6相同的按钮，第8，第12行是越来越选择什么，我做错了，我的适配器类

这是因为观点被重用。你必须设置holder.mgroup中的其他人，如果（convertView == NULL）

everybody i am creating a custom listview with dynamic radiobuttons adding to radiogroup upto that i am getting what i want but when i try to select one radio button in first row then automatically first button in 5th ,9th,13 row is getting selected and when i select any button in second row then same button in 6th,8th,12th row is getting selected what i am doing wrong here and my adapter class
public class InteractiveArrayAdapter extends ArrayAdapter<Model> {
String tag = "Events";
private final List<Model> list;
private final Activity context;
public InteractiveArrayAdapter(Activity context, List<Model> list) {
super(context, R.layout.rowbuttonlayout, list);
this.context = context;
this.list = list;
}
static class ViewHolder {
protected TextView text;
protected CheckBox checkbox,checkbox1;
protected RadioGroup mgroup;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
Log.d(tag," 3");
View view = null;
if (convertView == null) {
LayoutInflater inflator = context.getLayoutInflater();
view = inflator.inflate(R.layout.rowbuttonlayout, null);
final ViewHolder viewHolder = new ViewHolder();

//viewHolder.checkbox = (CheckBox) view.findViewById(R.id.check);
//viewHolder.checkbox1 = (CheckBox) view.findViewById(R.id.checkbox1);
viewHolder.mgroup = (RadioGroup) view.findViewById(R.id.radioGroup1);
final RadioButton[] mbutton=new RadioButton[5];
for(int l=0;l<5;l++){
mbutton[l]=new RadioButton(context);
mbutton[l].setText("test"+l);
viewHolder.mgroup.addView(mbutton[l]);
}
viewHolder.mgroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {

// do something with text
Log.d(text," event1");
return;

}

i am posting my working code so that it will be helpfull to others have a look at it
public class InteractiveArrayAdapter extends ArrayAdapter<Model> implements OnClickListener {
String tag = "Events";
private final List<Model> list;
private final Activity context;
int li,jh;
public InteractiveArrayAdapter(Activity context, List<Model> list) {
super(context, R.layout.rowbuttonlayout, list);
this.context = context;
this.list = list;
}
static class ViewHolder {
protected TextView text;
protected CheckBox checkbox,checkbox1;
protected RadioGroup mgroup;
protected RadioButton mbutton;
}
@Override
public View getView( final int position, View convertView, ViewGroup parent) {
//Log.d(tag," 3");
View view =null;
if (convertView == null) {
//System.out.println("ok");
LayoutInflater inflator = context.getLayoutInflater();
view = inflator.inflate(R.layout.rowbuttonlayout, null);
final ViewHolder viewHolder = new ViewHolder();
viewHolder.text = (TextView) view.findViewById(R.id.label);
viewHolder.mgroup = (RadioGroup) view.findViewById(R.id.radioGroup1);
final RadioButton[] mbutton=new RadioButton[5];
for(int l=0;l<5;l++){
mbutton[l]=new RadioButton(context);
mbutton[l].setText("test"+l+position);
mbutton[l].setId(l+1);
mbutton[l].setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
RadioButton byt=(RadioButton) v;
byt.isChecked();
byt.getId();
Model element = (Model) viewHolder.mgroup.getTag();
element.setBte(byt.getId());
element.gte((String) viewHolder.text.getText());
System.out.println("givemeresult");
}
});
viewHolder.mgroup.addView(mbutton[l]);
}
view.setTag(viewHolder);
viewHolder.mgroup.setTag(list.get(position));
} else {
view = convertView;
((ViewHolder) view.getTag()).mgroup.setTag(list.get(position));
}
ViewHolder holder = (ViewHolder) view.getTag();
view.getTag()).mgroup.getTag();
holder.text.setText(list.get(position).getName());
if (list.get(position).getName()==list.get(position).done()){
holder.mgroup.check(list.get(position).isSelected());
}
else {
holder.mgroup.clearCheck();
}
return view;
}
解决方案
That's because views are reused. You have to set holder.mgroup in the else of if(convertView == null)
Your code a bit changed by me:
public class InteractiveArrayAdapter extends ArrayAdapter<Model> {
String tag = "Events";
private final List<Model> list;
private final Activity context;
public InteractiveArrayAdapter(Activity context, List<Model> list) {
super(context, R.layout.rowbuttonlayout, list);
this.context = context.getApplicationContext();
this.list = list;
}
static class ViewHolder {
protected TextView text;
protected CheckBox checkbox,checkbox1;
protected RadioGroup mgroup;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
Log.d(tag," 3");
View view = convertView;
ViewHolder viewHolder = null;
final RadioButton[] mbutton = null;
if (view == null) {
LayoutInflater inflator = context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflator.inflate(R.layout.rowbuttonlayout, null);
viewHolder = new ViewHolder();
viewHolder.text = (TextView) view.findViewById(R.id.label);
//viewHolder.checkbox = (CheckBox) view.findViewById(R.id.check);
//viewHolder.checkbox1 = (CheckBox) view.findViewById(R.id.checkbox1);
viewHolder.mgroup = (RadioGroup) view.findViewById(R.id.radioGroup1);
// I'm not sure about this..
// Begin
mbutton=new RadioButton[5];
for(int l=0;l<5;l++){
mbutton[l]=new RadioButton(context);
mbutton[l].setText("test"+l);
viewHolder.mgroup.addView(mbutton[l]);
}
viewHolder.mgroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
public void onCheckedChanged(RadioGroup mRadioGroup, int checkedId) {
for(int i=0; i<mRadioGroup.getChildCount(); i++) {
RadioButton btn = (RadioButton) mRadioGroup.getChildAt(i);
//int t=table.indexOfChild(table_row);
//System.out.println(t);
int t=mRadioGroup.getId();
System.out.println(t);
if(btn.getId() == checkedId) {
String text = btn.getText().toString();
// do something with text
Log.d(text," event1");
return;
}
}
}
});
// End
view.setTag(viewHolder);
Log.d(tag,"me");
} else {
viewHolder = (ViewHolder) convertView.getTag();
// Begin
mbutton = viewHolder.mgroup;
// End
Log.d(tag,"meeee");
}
ViewHolder holder = (ViewHolder) view.getTag();
holder.text.setText(list.get(position).getName());
Log.d(tag," event7");
return view;
}
}
My implementation of an imageView (stripped):
public class DealAdapter extends ArrayAdapter<DealObject> {
private Context mContext;
private Activity mActivity;
private ArrayList<DealObject> mItems;
private int mXmlId;
public DealAdapter(Context context, int textViewResourceId, ArrayList<DealObject> items, Activity activity) {
super(context, textViewResourceId, items);
this.mContext = context.getApplicationContext();
this.mActivity = activity;
this.mItems = items;
this.mXmlId = textViewResourceId;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
//View v = null;
View v = convertView;
ViewHolder holder = null;
RemoteImageLoader imageLoader = new RemoteImageLoader(mContext, true);
RemoteImageView dealImage = null;
DealObject mo = mItems.get(position);
try {
if (v == null) {
LayoutInflater vi = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(mXmlId, null);
holder = new ViewHolder();
dealImage = (RemoteImageView) v.findViewById(R.id.deal_image);
holder.dealImage = dealImage;
v.setTag(holder);
} else {
// Get the ViewHolder back to get fast access to the ImageView.
holder = (ViewHolder) convertView.getTag();
holder.dealImage.setBackgroundColor(Color.WHITE);
dealImage = holder.dealImage;
}
if(mo.getImage() != null){
// calling reset is important to prevent old images from displaying in a recycled view.
dealImage.reset();
holder.dealImage.setImageUrl(imageUrl);
try {
holder.dealImage.loadImage();
}
catch (Exception ex) {
}
}
}
catch (Exception ex) {
ex.printStackTrace();
}
return v;
}
private static final class ViewHolder {
private RemoteImageView dealImage;
}
}
