Question

我在每一行都有一个自定义列表视图和一个单选按钮，它工作正常，但我希望从此代码中获取所选单选按钮的ID。例如，当我需要所选行的textview1值时，我该如何收集它？提前致谢。这是我的代码：

private static class Adapter extends BaseAdapter {
         private LayoutInflater mInflater;
         private int mResourceId = 0;
         private RadioButton mSelectedRB;
         private int mSelectedPosition = -1;


         public CitizenAdapter(Context context) {
                   mInflater = LayoutInflater.from(context);
                    }
         public int getCount() {
                    return array.size();
                    }
         public Object getItem(int position) {
                        return position;
                    }
         public long getItemId(int position) {
                        return position;
                    }       
         public View getView(final int position, View convertView, ViewGroup parent) {
                final ViewHolder holder;
                    if (convertView == null) {
                        convertView = mInflater.inflate(R.layout.table_row_citizen, null);
                        holder = new ViewHolder();
                        holder.text1 = (TextView) convertView.findViewById(R.id.TextView01);
                        holder.text2 = (TextView) convertView.findViewById(R.id.TextView02);                            
                        holder.button = (RadioButton)convertView.findViewById(R.id.radioButtonCitizen);                                                     

                        convertView.setTag(holder);

                    } else {
                        holder = (ViewHolder) convertView.getTag();
                    }       
                   holder.text1.setText(array1.get(position));
                   holder.text2.setText(array2.get(position));

                   holder.button.setOnClickListener(new OnClickListener() {
                     @Override
                     public void onClick(View v) {
                         if((position != mSelectedPosition && mSelectedRB != null)){
                             mSelectedRB.setChecked(false);
                         }
                         mSelectedPosition = position;
                         mSelectedRB = (RadioButton)v;
                     }
                 });

                     if(mSelectedPosition != position){
                         holder.button.setChecked(false);
                     }else{
                         holder.button.setChecked(true);
                         if(mSelectedRB != null && holder.button!= mSelectedRB){
                             mSelectedRB = holder.button;
                         }
                     }                      
            return convertView;
           }    

             static class ViewHolder {      
                  TextView text1;
                  TextView text2;                     
                  RadioButton button;
                }               
            }

Answer 1

假设您需要访问TextView方法中的onClick

@Override
public void onClick(View v) {
    if((position != mSelectedPosition && mSelectedRB != null)){
        mSelectedRB.setChecked(false);
    }
    mSelectedPosition = position;
    mSelectedRB = (RadioButton)v;
    View containerView = (View)v.getParent();
    TextView textView1 = (TextView)containerView.findViewById(R.id.TextView01);
}

编辑：

我发现您已将holder对象声明为final。在这种情况下，您可以直接从事件侦听器中访问holder.text1和holder.text2对象。

Answer 2

我想从此代码中获取所选单选按钮的ID。

您必须使用setTag & get getTag属性来获取所选单选按钮的实际id，

holder.button.setTag(position);  

holder.button.setOnClickListener(new View.OnClickListener() {  
                public void onClick(View v) {   
                 int pos = (Integer) v.getTag();
                 Log.i("ID of radiobutton","Order Edit @ position : " + pos); 
                 String _Str1=array1.get(pos);
                 String _Str2=array2.get(pos);
                 }       
                });

这样您就可以从行中获得textview的确切值。

按钮onClick

中的代码如下

 int selected_radioISAwayGroup = holder.radioISAwayGroup.getCheckedRadioButtonId();
                holder.radioISAwayButton = (RadioButton) findViewById(selected_radioISAwayGroup);

                System.out.println("holder.radioISAwayButton:"+holder.radioISAwayButton.getText().toString());
                if(holder.radioISAwayButton.getText().toString().equalsIgnoreCase("Pre"))
                {
                    //Count +1 for presents
                }
                else if(holder.radioISAwayButton.getText().toString().equalsIgnoreCase("Abs"))
                {
                    //Count +1 for Absents
                }
                else
                {
                    //Count +1 for Half
                }
