java - 适配器 ListView 中的 onTouchListener 使 onItemClickListener 未运行

Question

我为我的 ListView 创建自定义适配器。在 getView 方法中，我在自定义适配器中为 LinearLayout 设置了 onTouchListener。出于某种原因，我的 ListView 中的 onItemClickListener 无法运行。这是我的自定义适配器 TransactionAdapter 方法的代码:

public class TransactionAdapter extends BaseAdapter {
    private LayoutInflater inflater;
    private ArrayList<CTransaction> transactions;

    public TransactionAdapter(Context context, ArrayList<CTransaction> transactions){
        inflater = LayoutInflater.from(context);
        this.transactions = transactions;
    }

    @Override
    public int getCount() {
        return transactions.size();
    }

    @Override
    public Object getItem(int position) {
        return transactions.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        final View view = convertView = inflater.inflate(R.layout.detail_transaction, parent, false);

        LinearLayout llBackground = (LinearLayout)convertView.findViewById(R.id.llBackground);

        llBackground.setOnTouchListener(new View.OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN:
                    v.setBackground(view.getResources().getDrawable(R.drawable.border_clicked));
                    break;
                case MotionEvent.ACTION_UP:
                    v.setBackground(view.getResources().getDrawable(R.drawable.border));
                    v.performClick();
                    break;
                case MotionEvent.ACTION_CANCEL:
                    v.setBackground(view.getResources().getDrawable(R.drawable.border));
                    break;
                }

                //Tried to use this but not working
                view.onTouchEvent(event);

                return true;
            }
        });

        return convertView;
    }

}

这是我的 setAdapter 和 onItemClickListener 用于 ListView:

    lvTransaction = (ListView)findViewById(R.id.lvTransaction);
    TransactionAdapter adapter = new TransactionAdapter(this, transactions);
    lvTransaction.setAdapter(adapter);
    lvTransaction.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
            final int positionSelected = position;

            AlertDialog.Builder ad = new AlertDialog.Builder(HistoryActivity.this);
            //Show the AlertDialog
        }
    });

您必须返回 false 才能传播触摸事件，这样点击监听器才能捕获点击事件:

   llBackground.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                v.setBackground(view.getResources().getDrawable(R.drawable.border_clicked));
                break;
            case MotionEvent.ACTION_UP:
                v.setBackground(view.getResources().getDrawable(R.drawable.border));
                v.performClick();
                break;
            case MotionEvent.ACTION_CANCEL:
                v.setBackground(view.getResources().getDrawable(R.drawable.border));
                break;
            }
            return false;
        }
    });
