Question

I have small problem in android for Multichoice dialog box.

I have done with this below code for showing a multichoice dialog box and calling that on button click event.
I have set Title, Message, Button and also add Items to the dialog box.

I can see the title, Message and Button that I have set, but I am unable to see the items which I am adding. for that I have googled and almost tried all the code which I found in searching. All approaches not helped me.

Here is my code…

final String[] Values={"Red","Green","Blue"}; 
final boolean[] selCrayons={true,false,true};
AlertDialog.Builder dialog=new AlertDialog.Builder(this);
dialog.setTitle("Crayons List");
dialog.setMessage("Select your favouriate Crayon");
dialog.setMultiChoiceItems(Values,selCrayons,new DialogInterface.OnMultiChoiceClickListener() {
    @Override
    public void onClick(DialogInterface arg0, int arg1, boolean arg2) {
        // TODO Auto-generated method stub
        if(arg2) {
            Toast.makeText(getApplicationContext(), "Selected Color is " + Values[arg1],Toast.LENGTH_LONG).show();
        }
    }
});
dialog.setPositiveButton("SAVE",new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
    // TODO Auto-generated method stub
    }
});
AlertDialog alertDialog=dialog.create();
    alertDialog.show();
}

Answer 1

setMessage and setMultiChoiceItems will not work together. Remove setMessage and you will be able to see the multi-choice item list.

If there is a need to use message and multi-choice list together, you can use your own custom view for the dialog.

For how to set custom view, you can refer AlertDialog.Builder setView (View view) method.
