Question

I’m making an app and I’d like to help the user the first time he uses my app. I know that some others help the user with a layer that tells him what to do with a transparent background. And…I’d like to do this but I can’t find any way.

Someone see what I’m talking about?

There are of course several different ways of doing this, the simplest is probably displaying a Dialog, and changing the layout of the Dialog to match what you want to help the user with.

// Create a new Dialog
    dialog = new Dialog(this);

// Set the content of the dialog
    dialog.setContentView(R.layout.your_help_layout);

// Define the button            
    Button close_button = (Button)dialog.findViewById(R.id.your_close_button);

// Set onClickslistener
    close_button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            dialog.dismiss();           
        }
    });

// Show the dialog 
dialog.show();

in the XML you can set the background to:

android:background="@android:color/transparent"

If you have a TextView or ImageView inside of your xml for the dialog, you can simply just change the helping text/image by defining it the same wat as with the button and changing it when appropriate.
