列表视图中的复选框状态 onItemLongClick

Question

我有一个列表视图，当您 select 一行时，它的复选框变为选中/未选中状态。但是，我有一个显示对话框的 onItemLongClick。

问题是当我长按列表视图中的一行时，它会变成选中状态，我不希望这种情况发生，我只需要它来显示一个对话框。这让我感到困惑，因为当我使用 onItemLongClick.

时也会调用 onItemClick

Here's the code for onItemClick:

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @RequiresApi(api = Build.VERSION_CODES.N)
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            CheckBox checkBox = (CheckBox)view.findViewById(R.id.checkmark);
            TextView tv3 = (TextView)view.findViewById(R.id.tx_amount);
            String shitts = listView.getItemAtPosition(position).toString();
            HashMap<String, String> data = new HashMap<>();
            AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
            try {
                checkBox.setChecked(!checkBox.isChecked());
                String[] a = shitts.split(", ");
                String[] sep = a[0].split("=");
                String betamount = sep[1];
                String[] sepx = a[2].split("=");
                String betnumber = sepx[1];
                String showbetnumber = betnumber.replaceAll("[;/:*?\"<>|&{}']","");

                if(checkBox.isChecked()){
                    hash.put(showbetnumber,tv3.getText().toString());
                }else {
                    tv3.setText(betamount);
                    checked.removeAll(Collections.singletonList(position));
                    hash.remove(showbetnumber,tv3.getText().toString());
                }
            }catch (Exception e){
            }
        }
    });

and here's the code for onItemLongClick

listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
        @Override
        public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
            TextView txAmt = view.findViewById(R.id.tx_amount);
            AlertDialog.Builder alert = new AlertDialog.Builder(MainActivity.this);
            alert.setTitle("Enter Amount:");
            final EditText input = new EditText(MainActivity.this);
            input.setInputType(InputType.TYPE_CLASS_NUMBER);
            input.setRawInputType(Configuration.KEYBOARD_12KEY);
            alert.setView(input);
            alert.setPositiveButton("enter", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {
                    String x = input.getText().toString();
                    txAmt.setText(x);
                }
            });
            alert.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {
                    //Put actions for CANCEL button here, or leave in blank
                }
            });
            alert.show();
            return false;
        }
    });

感谢任何帮助！

Answer 1

创建一个布尔值 isLongClick 并将其设置为 false。

onItemLongClick()，将isLongClick设为true。

在您的对话框中，当单击任何按钮或关闭对话框时，再次将 isLongClick 设置为 false。

最后，将所有代码包装在 onItemClick() 中：

if (!isLongClick) { 
    // onItemClick() code
}
