Dialog open twice on fast click of button

Question

I have Button, which on clicking, displays a Dialog. Everything works like a charm, but if I double click the button or click the button fast, the Dialog opens two or three times. I have to click the back button twice or thrice to dismiss the Dialog.

I have searched for related questions on SO, but most of the answers suggest disabling the button or to use a variable and setting it to true and false, which is not my requirement.

If anyone knows how to solve this problem, please help me.

Code I have used

// Delete item on click of delete button
holder.butDelete.setOnClickListener(new OnClickListener() {         
@Override
    public void onClick(View v) {
        Dialog passwordDialog = new Dialog(SettingsActivity.this);      
        passwordDialog.show();
    }
});

Answer 1

You have to just check whether your Dialog is already shown or not:

Dialog passwordDialog = new Dialog(SettingsActivity.this);
holder.butDelete.setOnClickListener(new OnClickListener() {           
    @Override
    public void onClick(View v) {                  
        if(!passwordDialog.isShowing()) {
            passwordDialog.show();
        }
    }
});

Update:

If this doesn't work in your case, then in your activity declare globally:

Dialog passwordDialog = null;

and on Button's click:

holder.butDelete.setOnClickListener(new OnClickListener() {           
    @Override
    public void onClick(View v) {                  
        if(passwordDialog == null) {
            passwordDialog = new Dialog(SettingsActivity.this); 
            passwordDialog.show(); 
        }
    }
});
