CodePudding user response：

don't build your dialog in first line (create() call), use AlertDialog.Builder instance, set "possitive" and "negative" buttons on this (also title, message etc.), then call create() or even simpler show()

check out sample HERE

// initial builder and msg setup
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Close app?").setTitle("Exit");

// can't close dialog with e.g. back button, must be picked on of buttons
builder.setCancelable(false); 

// buttons setup
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {  
    public void onClick(DialogInterface dialog, int id) {  
        finish(); // closing Activity
    }  
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener() {  
    public void onClick(DialogInterface dialog, int id) {
    
    }  
});
builder.show();

dialog will close automatically when any button clicked, the one with "Yes" will close whole Activity, "No" is empty and you will stay in (looks like empty) Activity

CodePudding user response：

As per error , it looks like method with parameter types that you are using is not there . So basically you have three choice to use

 1. setButton(int,CharSequence,Message)
 2. setButton(int,CharSequence,OnClickListener)
 3. setButton(int,CharSequence,Drawable,OnClickListener)
