android - ムービングツーイメージビューの問題

Question

こんにちは私は2つの画像ビューを個別に移動しようとしています。私の問題は、最初のビューを正しく移動できるのに、2番目のビューに問題があることです。タッチするとすぐに画面から移動します。両方のImageViewが同じ場所にある場合は正常に機能していますが、質問が非常に基本的なものである場合は、別の申し訳ありませんが必要です。

int windowwidth;
    int windowheight;      
    ImageView ima1,ima2;
    Rect rect=null;

    private android.widget.RelativeLayout.LayoutParams layoutParams ;
   // private android.widget.RelativeLayout.LayoutParams layoutParams ;
    //private android.widget.RelativeLayout.LayoutParams layoutParams ;         

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.touch);

       /* Display display = getWindowManager().getDefaultDisplay(); 
        int width = display.getWidth();
        int height = display.getHeight();*/


        windowwidth = getWindowManager().getDefaultDisplay().getWidth()-130; 
        windowheight = getWindowManager().getDefaultDisplay().getHeight()-165;

        System.out.println("width" +windowwidth);
        System.out.println("height" +windowheight);             

        ima1 = (ImageView)findViewById(R.id.icon);
        ima2 = (ImageView)findViewById(R.id.icon1);
        ima2.setX(250);
        ima2.setY(1000);
        ima1.setOnTouchListener(new View.OnTouchListener() {  

            public boolean onTouch(View v, MotionEvent event) {

                layoutParams = (RelativeLayout.LayoutParams) ima1.getLayoutParams();

              //  layoutParams = (RelativeLayout.LayoutParams ima1.getLayoutParams();

                switch(event.getAction())

                {
                    case MotionEvent.ACTION_DOWN:                           
                        break;                   
                    /*case MotionEvent.ACTION_CANCEL:
                        break;*/
                    case MotionEvent.ACTION_MOVE:
                        int x_cord = (int) event.getRawX();
                        int y_cord = (int) event.getRawY();

                        System.out.println("value of x" +x_cord);
                        System.out.println("value of y" +y_cord);            

                        if (x_cord > windowwidth) {
                            x_cord = windowwidth;
                        }

                        ima1.setLayoutParams(layoutParams);
                        break;

                }  
                return true;
            }
        });


        ima2.setOnTouchListener(new View.OnTouchListener() {

                        int y_cord = (int) event.getRawY();


                        System.out.println("value of x1" +x_cord);
                        System.out.println("value of y1" +y_cord);                          

                        if (x_cord > windowwidth) {
                            x_cord = windowwidth;
                        }
                        if (y_cord > windowheight) {
