Question

I have ListView with several elements of type LinearLayout. How to make slide effect on they like as in the contacts(when a contact slide on the right then there is a call, in the other case message is written).

Answer 1

That is view pager that your talking about
Here is an example that i have made for you

The ViewPageExample.java file

public class ViewPageExample extends Activity {

private ViewPager mViewPager;
private Context mContext;
private MyPageAdatper mAdapter;


@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mContext = this;

mAdapter = new MyPageAdatper();
mViewPager = (ViewPager) findViewById(R.id.mViewPager);
mViewPager.setAdapter(mAdapter);
}

private class MyPageAdatper extends PagerAdapter{


        @Override
        public int getCount() {
               //Since only contacts messages and call logs were mentioned by you
                return 3;
        }


        @Override
        public Object instantiateItem(View collection, int position) {
            LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View mView = null ;
            switch(position){
                case 0:
                    mView   =   inflater.inflate(R.layout.contacts, null);  
                    Button btn1 = (Button) mView.findViewById(R.id.button1);
                    btn1.setOnClickListener(new OnClickListener() {

                        @Override
                        public void onClick(View v) {
                            Toast.makeText(getApplicationContext(), "Clicked", Toast.LENGTH_SHORT).show();
                        }
                    });
                break;

                case 1:
                    mView   =   inflater.inflate(R.layout.messages, null);   
                break;

                case 2:
                    mView   =   inflater.inflate(R.layout.callogs, null);   
                break;
            }




                ((ViewPager) collection).addView(mView,0);

                return mView;
        }


        @Override
        public void destroyItem(View collection, int position, Object view) {
                ((ViewPager) collection).removeView((View) view);
        }



        @Override
        public boolean isViewFromObject(View view, Object object) {
                return view==((View)object);
        }


        @Override
        public void finishUpdate(View arg0) {}


        @Override
        public void restoreState(Parcelable arg0, ClassLoader arg1) {}

        @Override
        public Parcelable saveState() {
                return null;
        }

        @Override
        public void startUpdate(View arg0) {}

}
