Question

我试图创建一个列表，其中该列表上的每个元素都有6个按钮。当我在该列表的第二个位置时，我设置OnClickListener的按钮将覆盖第一个位置按钮的功能。

我在适配器中实现了getView函数，如下所示：

@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
                public void onClick(View v) {
                    Intent i = new Intent(inflater.getContext(), Advertisement.class);
                    //i.putExtra("id", ((Button) v).getHint().toString());
                    i.putExtra("id", Integer.toString(data.get(Integer.parseInt(((Button) v).getHint().toString())).mID));
                    i.putExtra("name", data.get(Integer.parseInt(((Button) v).getHint().toString())).mName);
                    i.putExtra("bank", BanksInfo.MERCANTIL);
                    inflater.getContext().startActivity(i);
                }

            });
        }
        if(data.get(i).mDicName.equals("Venezuela")) {
            mViewHolder.buttons[i%6].setBackgroundResource(R.drawable.bank_venezuela);

Answer 1

永远不要在getView中附加onClicklistener。而是使用：

yourGridView.setOnItemClickListener(..

那是因为getView重用旧视图及其点击方法。因此，经过一些滚动后，您的图像视图是正确的，但您的点击方法完全混乱，可能在每个图像后面！希望它有所帮助。

适配器覆盖按钮onclicklistener
