在OnTouch方法中,仅当标志设置为true时才允许缩放和移动.移动和缩放后,将标志设置为false.

这是一些伪代码：

public class MyActivity extends Activity {

   private boolean longClick = false;

   public boolean onTouch(View v,MotionEvent event) {
      if (longClick) {
         // do scaling and moving ...
         longClick = false;
      }
      return false;
   }

   public boolean onLongClick(View v) {
      longClick = true;
      return false;
   }
}
