<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

     <RelativeLayout
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_centerHorizontal="true"
         android:layout_centerVertical="true"
         android:layout_margin="30dp"
         android:background="@drawable/backgroundblankred" >

         <Button
             android:id="@+id/button1"
             android:layout_width="100dp"
             android:layout_height="100dp"
             android:background="@drawable/eeclevelfirstblackbuton" />

     </RelativeLayout>

</RelativeLayout>

Button buttonblack;
int score=0;



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
    WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.tested);


    buttonblack = (Button)findViewById(R.id.black1);
    buttonblack.setOnClickListener(new View.OnClickListener() {

              public void onClick(View v){
             //If clicked, Move the button randomly
                                         }                
            });

Hope this video helps for the 1st part: Android App Development for Beginners - 34 - Animations and Transitions.

For second part you may use a loop like this:

while(true){
    delay(time);//time can be taken input from any EditText.
    placeButton(x,y); // x and y are random numbers
}

generate random integers within your view area random number

1)this should be the pseudo code you are looking for

int x = rnd(view.getX(), view.getX()+view.getWidth());
int y = rnd(view.getY(), view.getY()+view.getHeight());
view.setTranslationX(x);
view.setTranslationY(y);

2) use a thread with a sleep duration you can modify, the ui changes needs be called on the main thread, use a handler or asynctask for that
