Question

我正在使用this library来创建一个应用程序，其中列出了需要折叠方面的内容。但是每个视图（该列表中的每个元素）都有6个按钮，我无法从适配器向每个按钮添加clickListener，因为它会覆盖最后一个位置的clickListener。我使用another library但它适用于OpenGL，而且它有点儿错误。

如何设置每个按钮的特定功能？

我已在适配器中设置OnClickListener，但它不起作用：

public class CardQueryAdapter extends BaseAdapter{
private int cant;
LayoutInflater inflater;
private ArrayList<Cards> data;
DataBaseConnectionManager mDataBase;
int[] buttons=new int[]{R.id.button1,R.id.button2,R.id.button3,
        R.id.button4,R.id.button5,R.id.button6};

public CardQueryAdapter(Context context, DataBaseConnectionManager mDataBase) {
    inflater = LayoutInflater.from(context);
    this.mDataBase = mDataBase;
    data = mDataBase.getUserCards();
    cant = data.size();
    System.out.println("Size= "+cant+" "+(int) Math.ceil(cant/6.0));
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder mViewHolder = null;
    System.out.println("position: "+position);

    if (convertView == null) {

        mViewHolder = new ViewHolder();
        convertView = inflater.inflate(R.layout.activity_card_query, parent, false);

        mViewHolder.buttons[0] = (Button) convertView.findViewById(R.id.button1);
        mViewHolder.buttons[1] = (Button) convertView.findViewById(R.id.button2);
        mViewHolder.buttons[2] = (Button) convertView.findViewById(R.id.button3);
        mViewHolder.buttons[3] = (Button) convertView.findViewById(R.id.button4);
        mViewHolder.buttons[4] = (Button) convertView.findViewById(R.id.button5);
        mViewHolder.buttons[5] = (Button) convertView.findViewById(R.id.button6);

        convertView.setTag(mViewHolder);

    }else{

        mViewHolder = (ViewHolder) convertView.getTag();

    }

    int j;
    if(cant<=6) j=cant;
    else if(getCount()-1!=position)j=6*position+6;
        else j=cant;

    System.out.println("Caso: "+6*position+" "+j);
    for(int i=6*position;i<j;i++){
        System.out.println("Bank: "+data.get(i).mID+" "+data.get(i).mDicName);
        mViewHolder.buttons[i%6].setGravity(Gravity.CENTER_HORIZONTAL);
        if(data.get(i).mDicName.equals("Mercantil")) {
            mViewHolder.buttons[i%6].setBackgroundResource(R.drawable.bank_mercantil);
            mViewHolder.buttons[i%6].setText(data.get(i).mName);
            mViewHolder.buttons[i%6].setTextColor(Color.WHITE);
            //button.setHint(Integer.toString(data.get(i).mID));
            mViewHolder.buttons[i%6].setHint(Integer.toString(i));
            mViewHolder.buttons[i%6].setOnClickListener(new OnClickListener(){

                @Override

}

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return (int) Math.ceil(cant/6.0);
}

public void setCount(int cant) {
    this.cant = cant;
}

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

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

static class ViewHolder{
    private Button[] buttons = new Button[6];
}

}

在下面的图像中，您可以看到它在第一个和第二个位置的外观，但是按钮7正在替换按钮1 clickListener：

How looks the first position

How looks the second position

解决

The library已更新，但存在问题。现在效果很好。

Answer 1

第7个按钮覆盖第1个按钮的问题在于您编写的逻辑。我在这段代码中怀疑它

int j;
if(cant<=6) j=cant;
else if(getCount()-1!=position)j=6*position+6;
    else j=cant;

System.out.println("Caso: "+6*position+" "+j);
for(int i=6*position;i<j;i++){
    System.out.println("Bank: "+data.get(i).mID+" "+data.get(i).mDicName);

你能做什么？ 将log.d慷慨地放入代码中，看看日志是否应该打印出来。根据日志，您可以检查哪个按钮绑定了呼叫。在i内打印for loop，并在每次选择哪个按钮时进行检查。

适配器在此库上运行错误
