Android 使用 CheckBoxes 自定义 ListView 搜索，过滤器不工作

Question

我正在开发 Android 应用程序，我有一个带复选框的自定义列表视图，我可以 select 复选框并获得 selected 值。但是当我尝试搜索某些特定名称时，应用程序崩溃了。

这是我的代码，我想我遗漏了什么。

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CLass

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：

                                                                       at android.os.Looper.loop(Looper.java:148)

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，并通过正确参考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进行搜索，那里的搜索很好，但我应用搜索时丢失了复选框的选中状态，现在我正在使用 customadapter，我如何才能在搜索列表视图时获得复选框的正确引用。我将非常感谢任何帮助，我几乎花了两天时间，并搜索了所有互联网，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

The java.util.ArrayList.addAll(Collection c) method appends all of the elements in the specified collection to the end of this list, in the order that they are returned by the specified collection's Iterator.

错误

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

对

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 ，其次你在空列表上尝试@IntelliJ Amiya answer
