android move view horizontally on touch in android 2.2

in this project we have to use following animation library.
this library can be downloaded from http://nineoldandroids.com/

please make following layout named activity_main.xml


<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity"
    android:id="@+id/container" >

    <LinearLayout
        android:id="@+id/llMotion"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@android:color/darker_gray"
        android:padding="10dp" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="10dp"
            android:text="@string/hello_world" />

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="button" />
    </LinearLayout>

</RelativeLayout>


then use following code to move view vertically on touch


package com.example.viewgesture;

import android.app.Activity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.LinearLayout;
import android.widget.RelativeLayout;

import com.nineoldandroids.view.ViewPropertyAnimator;

public class MainActivity extends Activity  {
private LinearLayout llMotion;
private RelativeLayout llContainer;
private float default_y = 0;
private Boolean moveable = false;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
llMotion = (LinearLayout) findViewById(R.id.llMotion);
llContainer = (RelativeLayout) findViewById(R.id.container);

llContainer.setOnTouchListener(new OnTouchListener() {

@Override
public boolean onTouch(View v, MotionEvent event) {

float y = event.getY();
int action = event.getAction();
if (action == MotionEvent.ACTION_DOWN && y >= default_y
&& y < (default_y + llMotion.getHeight())) {
moveable = true;
} else if (action == MotionEvent.ACTION_UP && moveable) {
moveable = false;
default_y = y;
} else if (action == MotionEvent.ACTION_MOVE && moveable) {
ViewPropertyAnimator.animate(llMotion).y(y);

}

return true;

}
});

}


}
