使用 CheckBoxes 进行 Android 自定义 ListView 搜索，过滤器不起作用

Question

我正在开发 Android 应用程序，我有一个带有复选框的自定义列表视图，我可以选择复选框并获取选定的值。但是当我尝试搜索某些特定名称时应用程序崩溃。

这是我的代码，我想我遗漏了一些东西。

public class MyAdapter extends BaseAdapter {
    private ArrayList<InfoRowdata> arraylisto;
    private List<InfoRowdata> worldlist = null;

    Context mContext;
    LayoutInflater inflater;

    public MyAdapter(Context context, List<InfoRowdata> worldpopulationlist) {
        mContext = context;
        inflater = LayoutInflater.from(mContext);
        this.worldlist = worldpopulationlist;

        this.arraylisto = new ArrayList<InfoRowdata>();
        this.arraylisto.addAll(worldpopulationlist);

    }

    public class ViewHolder {
        TextView Name;
        CheckBox cb;

    }
    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return data.length;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return worldlist.get(position);
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

 public View getView(final int position, View view, ViewGroup parent) {
final ViewHolder holder;
if (view == null) {
    holder = new ViewHolder();
    view = inflater.inflate(R.layout.creditunionrow, null);
    // Locate the TextViews in listview_item.xml
    holder.Name = (TextView) view.findViewById(R.id.label);
    holder.cb = (CheckBox) view.findViewById(R.id.check);

    view.setTag(holder);
} else {
    holder = (ViewHolder) view.getTag();
}
// Set the results into TextViews
holder.Name.setText(worldlist.get(position).getName());
 // holder.cb.setChecked(worldlist.get(position).getChecked());


holder.cb.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Selection = "";
                count=0;
                String selecteditems = "";
                // TODO Auto-generated method stub
                if (infodata.get(position).isclicked) {
                    infodata.get(position).isclicked = false;

                } else {
                    infodata.get(position).isclicked = true;
                }
                for (int i = 0; i < infodata.size(); i++) {
                    if (infodata.get(i).isclicked) {
                   //System.out.println("Selectes Are == "+ data[i]);
                        selecteditems = selecteditems + data[i] + ",";
                    count++;
                    }
                }
                System.out.println("Selected Are == " + selecteditems);
                Selection = selecteditems;
            }



});
if (infodata.get(position).isclicked) {

    holder.cb.setChecked(true);
} else {
    holder.cb.setChecked(false);
}




// Listen for ListView Item Click
view.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View arg0) {

    }
});

return view;
}

    // Filter Class
    public void filter(String charText) {
        charText = charText.toLowerCase(Locale.getDefault());
        worldlist.clear();
        if (charText.length() == 0) {
            worldlist.addAll(arraylisto);
        } else {
            for (InfoRowdata wp : arraylisto) {
                if (wp.getName().toLowerCase(Locale.getDefault())
                        .contains(charText)) {
                    worldlist.add(wp);
                }
            }
        }
        notifyDataSetChanged();
    }

}

这是我的模型类

public class InfoRowdata {

public boolean isclicked=false;
public int index;
public String name;
/*public String strAmount;*/

public InfoRowdata(boolean isclicked,int index,String name/*,String strAmount*/)
{
    this.index=index;
    this.isclicked=isclicked;
    this.name=name;
    /*this.strAmount=strAmount;*/
}


public String getName() {
    return this.name;
}

public void setName(String name) {
    this.name = name;
}


public Boolean getChecked() {
    return isclicked;
}

public void setChecked(Boolean checked) {
    this.isclicked = checked;
}

}

我得到的异常：

这就是我使用edittext搜索列表视图的方式：

inputSearch.addTextChangedListener(new TextWatcher()
    {
        public void afterTextChanged(Editable s)
        {
            //Abstract Method of TextWatcher Interface.
        }
        public void beforeTextChanged(CharSequence s,int start, int count, int after)
        {

        }
        public void onTextChanged(CharSequence s,int start, int before, int count)
        {



            String text = inputSearch.getText().toString().toLowerCase(Locale.getDefault());
            adapter.filter(text);
        }
    });

我不知道我在哪里遗漏了一些东西，我想检查随机复选框，并通过正确引用选中的复选框对它们进行搜索，首先我没有使用自定义适配器，在那里搜索很好，但我丢失了应用搜索时复选框的选中状态，现在我正在使用 customadapter，如何在搜索列表视图时正确引用复选框。我将非常感谢您的帮助，我几乎花了两天时间，搜索了所有互联网，但找不到任何实现带有复选框和搜索功能的列表视图的示例。

Answer 1

java.util.ArrayList.addAll(Collection c) 方法 将指定集合中的所有元素附加到 此列表，按照指定的返回顺序 集合的迭代器。

错误

    this.arraylisto = new ArrayList<InfoRowdata>();
    this.arraylisto.addAll(worldpopulationlist); // Problem Here

正确

this.arraylisto = new ArrayList<InfoRowdata>();
this.arraylisto.addAll(worldlist); // Rectify here

和

 @Override
public int getCount() {
    // TODO Auto-generated method stub
    return worldlist.size();
}

Answer 2

首先不要在CheckBox 上使用onClickListener 使用setOnCheckedChangeListener，其次你有空列表尝试@IntelliJ Amiya 答案
