Pracuję nad projektem użytkownika, aby przenieść obraz w jednej pozycji do innej pozycji na ekranie. Napisałem przykładowy kod, aby przenieść obraz, ale problem polega na tym, że jeśli przesunę jeden obraz, sąsiedni obraz również zacznie się poruszać. Oto przykładowy kod.

Main.java

public class MainActivity extends Activity  {
   int windowwidth;
   int windowheight;    
   ImageView ima1,ima2;

   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.main);

         windowwidth = getWindowManager().getDefaultDisplay().getWidth();
         windowheight = getWindowManager().getDefaultDisplay().getHeight();

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

         ima1 = (ImageView)findViewById(R.id.imageview1);
         ima1.setOnTouchListener(new View.OnTouchListener() {  

public boolean onTouch(View v, MotionEvent event) {
       layoutParams = (RelativeLayout.LayoutParams) ima1.getLayoutParams();

         switch(event.getAction())                   
            {
              case MotionEvent.ACTION_DOWN:                          
                    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;
                       }
                    if (y_cord > windowheight) {
                        y_cord = windowheight;
                       }
             layoutParams.leftMargin = x_cord-25;
             layoutParams.topMargin = y_cord-25;
             //   layoutParams.rightMargin = x_cord-25;
             //   layoutParams.bottomMargin = y_cord-25;
             ima1.setLayoutParams(layoutParams);
                     break;
               default: break;
              }  
               return true;
            }
         });

         ima2 = (ImageView)findViewById(R.id.imageview2);
         ima2.setOnTouchListener(new View.OnTouchListener() {         

     public boolean onTouch(View v, MotionEvent event) {
         layoutParams = (RelativeLayout.LayoutParams) ima2.getLayoutParams();
              switch(event.getActionMasked())
                 {
                   case MotionEvent.ACTION_DOWN:
                       break;
                   case MotionEvent.ACTION_MOVE:
                       int x_cord = (int) event.getRawX();
                       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) {
                            y_cord = windowheight;
                        }
                        layoutParams.leftMargin = x_cord - 25;
                        layoutParams.topMargin = y_cord - 75;
                        ima2.setLayoutParams(layoutParams);
                        break;
                    default: break;
                }
                return true;
            }
        });
       }
   }
