当自定义适配器的ListView检查吐司

问题描述

我想，当我在复选框选中的code返回那是在同一行文本视图的字符串只。

I want when I checked on check box the code returns string of text view that's in the same row only .

我使用LayoutInflater并具有code创建包含字符串列表中的其他类

i'm using LayoutInflater and another class which has code for creating list containing strings

我的code：

 public class InteractiveArrayAdapter extends ArrayAdapter<model> {


private final List<model> list;
  private final Activity context;

  public InteractiveArrayAdapter(Activity context, List<model> list) {
    super(context, R.layout.rep, list);
    this.context = context;
    this.list = list;

  }


  static class ViewHolder {
        protected TextView text;
        protected CheckBox checkbox;
      }

  public View getView(int position, View convertView, ViewGroup parent) {
        View view = null;
        if (convertView == null) {
          LayoutInflater inflator = context.getLayoutInflater();
          view = inflator.inflate(R.layout.rep, null);
          final ViewHolder viewHolder = new ViewHolder();
          viewHolder.text = (TextView) view.findViewById(R.id.TextView07);
          viewHolder.checkbox = (CheckBox) view.findViewById(R.id.CheckBox05);
          viewHolder.checkbox
              .setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

                @Override
                public void onCheckedChanged(CompoundButton buttonView,
                    boolean isChecked) {
                  model element = (model) viewHolder.checkbox
                      .getTag();
                  element.setSelected(buttonView.isChecked());

                }
              });
          view.setTag(viewHolder);
          viewHolder.checkbox.setTag(list.get(position));
        } else {
          view = convertView;
          ((ViewHolder) view.getTag()).checkbox.setTag(list.get(position));
        }
        ViewHolder holder = (ViewHolder) view.getTag();
        holder.text.setText(list.get(position).getName());
        holder.checkbox.setChecked(list.get(position).isSelected());
        return view;


      }

}

我的XML：

  <?xml version="1.0" encoding="utf-8"?>
  <AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<TableLayout
android:id="@+id/h103"
android:layout_width="match_parent"
android:layout_height="27dp"
android:layout_x="0dp"
android:layout_y="0dp"
android:background="@drawable/back1" >

<TableRow
    android:id="@+id/TableRow05"
    android:layout_width="match_parent"
    android:layout_height="27dp"
    android:layout_marginTop="4dp" >

    <CheckBox
        android:id="@+id/CheckBox05"
        android:layout_width="20dp"
        android:layout_height="20dp"
        android:layout_marginLeft="20dp"
        android:layout_marginTop="-4dp"
        android:button="@drawable/test" />

    <TextView
        android:id="@+id/TextView07"
        android:layout_width="220dp"
        android:layout_height="22dp"
        android:layout_marginLeft="23dp"
        android:layout_marginTop="-6dp"
        android:text="" />

    <TextView
        android:id="@+id/TextView08"
        android:layout_width="110dp"
        android:layout_height="22dp"
        android:layout_marginLeft="0dp"
        android:layout_marginTop="-4dp"
        android:text="095110263" />

</TableRow>

推荐答案

首先，在乌尔列表视图btnOk底部添加1按钮

First Add 1 button at bottom of ur list view btnOk

btnOk.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v)
            {
                // TODO Auto-generated method stub
                 StringBuffer responseText = new StringBuffer();


                 ArrayList<model> almodel = adapter.almodel;
                 responseText.append("The following were selected...\n");

                 for(int i=0;i<almodel.size();i++)
                 {
                     model m = almodel.get(i);
                     if(m.isSelected())
                     {

                      responseText.append("\n" + m.getName());

                     }

                  }


         Toast.makeText(getApplicationContext(),responseText,Toast.LENGTH_LONG).show();
