Ich arbeite am Projektbenutzer, um das Bild an eine andere Position auf dem Bildschirm zu verschieben. Ich habe einen Beispielcode geschrieben, um das Bild zu verschieben, aber das Problem ist, wenn ich ein Bild verschiebe, beginnt sich auch das benachbarte Bild zu verschieben. Hier ist der Beispielcode.

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;
            }
        });
       }
   }
