Android onOptionsItemSelected avoid double click

Question

How to avoid double click on my example, any solutions?

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (item.getItemId() == R.id.testing) {
                Dialog();
    return super.onOptionsItemSelected(item);
}

Answer 1

There is many way to achieve this. I am telling only sample example.

Just create a boolean variable in Activity class.

Boolean isClicked = false;

and then

 @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getItemId() == R.id.testing) {
    if (!isClicked){
//Change here as your flag is true
isClicked = true;
                    Dialog();
    }
        return super.onOptionsItemSelected(item);
    }

Then this dialog shows only one time. If any changes needed ask.
