[英]Checkbox state in listview onItemLongClick
I have a listview in which when you select a row, it's checkbox becomes checked / unchecked. 我有一个列表视图,当您选择一行时,它的复选框被选中/取消选中。 However, I have a
onItemLongClick
that displays a dialog. 但是,我有一个
onItemLongClick
,它显示一个对话框。
Problem is when I long-click a row in the listview, it becomes checked and I don't want that to happen, I just need it to display a dialog. 问题是当我长时间单击列表视图中的一行时,该行被选中并且我不希望发生这种情况,我只需要它显示一个对话框即可。 This is confusing me because the
onItemClick
is also called when I use onItemLongClick
. 这是困惑我,因为
onItemClick
当我使用也被称为onItemLongClick
。
Here's the code for
onItemClick
:这是
onItemClick
的代码:
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
这是
onItemLongClick
的代码
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;
}
});
Any help is appreciated! 任何帮助表示赞赏!
Create a boolean isLongClick
and set it to false
. 创建一个布尔
isLongClick
并将其设置为false
。
onItemLongClick()
, set isLongClick
to true
. onItemLongClick()
,将isLongClick
设置为true
。
On your dialog, set isLongClick
to false
again when any button is clicked or if the dialog was dismissed. 在对话框上,单击任何按钮或
isLongClick
对话框时,再次将isLongClick
设置为false
。
Finally, wrap all your code inside onItemClick()
in: 最后,将所有代码包装在
onItemClick()
中:
if (!isLongClick) {
// onItemClick() code
}
