拖放到多個位置

Question

我在Android Studio中爲自閉症兒童創建了一個時間表/日程安排應用程序，他們可以使用'活動圖像'將活動圖像'放入並拖動'到總共5個活動位置'每天（星期一，星期二等）。

我已命名每個IMAGELOCATION如下：

MONDAY：1A，1B，1C，1D，1E 星期二：2A，2B，2C，2D，2E 星期三：3A，3B，3C，4D， 3E THURDAY：4A，4B，4C，4D，4E FRIDAY：5A，5B，5C，5D，5E SATURDAY：圖6A，6B，6C，6D，6E 星期日：圖7A，7B，7C，7D，7E

我已經成功地對它進行了編碼，將「活動圖像」放置到位置1A，但是我不確定如何去編碼它的其餘位置。我曾嘗試複製並粘貼之前用於其他位置的代碼，但是當「拖放」圖像時，它會將相同圖像複製到所有已編碼的位置。

public class NewScheduleActivity extends AppCompatActivity { 

ImageView image1, image2, image3, image4, image5, image6, image7, image8, image9, image10; 
ImageView activityslotlocation1a, activityslotlocation1b, activityslotlocation1c, activityslotlocation1d, activityslotlocation1e; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.newschedulescreen); 


    image1 = (ImageView) findViewById(R.id.imageView1); 
    image2 = (ImageView) findViewById(R.id.imageView2); 
    image3 = (ImageView) findViewById(R.id.imageView3);

    image8 = (ImageView) findViewById(R.id.imageView8); 
    image9 = (ImageView) findViewById(R.id.imageView9); 
    image10 = (ImageView) findViewById(R.id.imageView10); 

    activityslotlocation1a = (ImageView) findViewById(R.id.activityslot1a); 
    activityslotlocation1b = (ImageView) findViewById(R.id.activityslot1b); 
    activityslotlocation1c = (ImageView) findViewById(R.id.activityslot1c); 
    activityslotlocation1d = (ImageView) findViewById(R.id.activityslot1d); 
    activityslotlocation1e = (ImageView) findViewById(R.id.activityslot1e); 

    image1.setOnLongClickListener(longClickListener);

    activityslotlocation1a.setOnDragListener(dragListener); 
    activityslotlocation1b.setOnDragListener(dragListener); 
    activityslotlocation1c.setOnDragListener(dragListener); 
    activityslotlocation1d.setOnDragListener(dragListener); 
    activityslotlocation1e.setOnDragListener(dragListener); 

} 

View.OnLongClickListener longClickListener = new View.OnLongClickListener() { 
    @Override 
    public boolean onLongClick(View v) { 
     ClipData data = ClipData.newPlainText("", ""); 
     View.DragShadowBuilder myShadowBuilder = new View.DragShadowBuilder(v); 
     v.startDragAndDrop(data, myShadowBuilder, v, 0); 
     return true; 

    } 
}; 

View.OnDragListener dragListener = new View.OnDragListener() { 

    @Override 
    public boolean onDrag(View v, DragEvent event) { 

     int dragEvent = event.getAction(); 
     final View view = (View) event.getLocalState(); 
     switch (dragEvent) { 

      case DragEvent.ACTION_DRAG_ENTERED: 

       break; 

      case DragEvent.ACTION_DRAG_EXITED: 

       break; 


      case DragEvent.ACTION_DROP: 

       // Location 1A 

       if (view.getId() == R.id.imageView1) { 
        activityslotlocation1a.setImageResource(R.drawable.art); 

       } else if (view.getId() == R.id.imageView2) {

       } else if (view.getId() == R.id.imageView6) {

       } else if (view.getId() == R.id.imageView10) { 
        activityslotlocation1a.setImageResource(R.drawable.pizzanight); 
       } 

       //view.animate() 
         //.x(activityslotlocation1a.getX()) 
         //.y(activityslotlocation1a.getY()) 
         //.setDuration(500) 
         //.start(); 

       MediaPlayer mymedia = MediaPlayer.create(NewScheduleActivity.this,R.raw.whoosh); 
       mymedia.start(); 

       break; 
     } 


     return true; 
    } 
};

我改變你的代碼一點，試試這個，但聽意見，並嘗試修剪代碼下來了一點。

private Imageview startview; 

View.OnDragListener dragListener = new View.OnDragListener() { 
@Override 
public boolean onDrag(View v, DragEvent event) { 
    int dragEvent = event.getAction(); 
    final View view = (View) event.getLocalState(); 
    switch (dragEvent) { 
     case DragEvent.ACTION_DRAG_ENTERED: 
      startview = v; 
      break; 
     case DragEvent.ACTION_DRAG_EXITED: 
      break; 
     case DragEvent.ACTION_DROP: 
      if(!startview) break; 
      if (view.getId() == R.id.imageView1) { 
       startview.setImageResource(R.drawable.art); 
      } else if (view.getId() == R.id.imageView2) { 
       startview.setImageResource(R.drawable.gohome); 
      } else if (view.getId() == R.id.imageView3) { 
      startview.setImageResource(R.drawable.bedtime); 
      } else if (view.getId() == R.id.imageView4) { 
       startview.setImageResource(R.drawable.watchamovie); 
      } else if (view.getId() == R.id.imageView5) { 
       startview.setImageResource(R.drawable.swimmingclass); 
      } else if (view.getId() == R.id.imageView6) { 
       startview.setImageResource(R.drawable.cooking); 
      } else if (view.getId() == R.id.imageView7) { 
       startview.setImageResource(R.drawable.blocks); 
      } else if (view.getId() == R.id.imageView8) { 
       startview.setImageResource(R.drawable.drink); 
      } else if (view.getId() == R.id.imageView9) { 
       startview.setImageResource(R.drawable.bedtimestory); 
      } else if (view.getId() == R.id.imageView10) { 
       startview.setImageResource(R.drawable.pizzanight); 
      } 
      startview = null; 
      MediaPlayer mymedia = MediaPlayer.create(NewScheduleActivity.this,R.raw.whoosh); 
      mymedia.start(); 
      break; 
    } 


    return true; 
}
