Question

I want to create the instruction, so when user press the next button I want to set to the
next layout page. I tried setContentView(R.layout.aboutus); but it looks like to set the new
layout to particular page.

Layout:

 <?xml version="1.0" encoding="UTF-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="horizontal" android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:background="#dddddd">
        <LinearLayout android:gravity="center" android:background = "@drawable/aboutus"
            android:orientation="vertical" android:layout_height="wrap_content"
            android:layout_width="wrap_content"/>
    </LinearLayout>

code :

 public void onItemClick(AdapterView<?> parent, View view, int position,
                long lg) {
            switch (position) {

            case 4:
                setContentView(R.layout.aboutus);
            }

        }

So, I want to know how to go to next layout without new activity and can be back to previous page. Thank you.

You should use a ViewFlipper.

Get a reference to the ViewFlipper:

ViewFlipper myViewFlipper = (ViewFlipper) findViewById(R.id.my_viewFlipper);

You then inflate each page as a view:

LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.your_layout_id, null);

And then add it to the ViewFlipper:

myViewFlipper.addView( view );

Then when the user hits the button for next page you call this method:

myViewFlipper.showNext();

Or if you want the previous page:

myViewFlipper.showPrevious();
