Question

我正在尝试在ViewFlipper中创建一个包含3个视图的幻灯片动画，当我在它们之间切换时，我得到一个空白区域。当我尝试在Action_Move中更改它们时，是否有任何方法可以删除视图之间的空间，以便它们看起来像是粘在一起？

这是XML：

<ViewFlipper 
    android:id="@+id/ViewFlipper1"
    android:layout_height="300dp"
    android:layout_width="300dp"
    android:background="#000000">

    <TextView 
        android:layout_width="300dp"
        android:layout_height="200dp"
        android:background="#aabbcc"/>

    <TextView 
        android:layout_width="300dp"
        android:layout_height="200dp"
        android:background="#cfcfcf"/>

    <TextView 
        android:layout_width="300dp"
        android:layout_height="200dp"
        android:background="#adadad"/>

</ViewFlipper>

这是我想要制作的动画：

float firstTouchX = 0;
float leaveTouchX = 0;
float firstTouchX2 = 0;
float leaveTouchX2 = 0;
float oldMoveTouchX = 0;
ViewFlipper VF = null;

public boolean dispatchTouchEvent(MotionEvent event) {

    VF =(ViewFlipper) findViewById(R.id.ViewFlipper1);
       int eventaction=event.getAction();
       final View currentView = VF.getCurrentView();

       switch(eventaction) {
        case MotionEvent.ACTION_DOWN:               

           firstTouchX = event.getX();
           oldMoveTouchX = firstTouchX;

           break;

        case MotionEvent.ACTION_MOVE:

        int deltaMovement = (int)(event.getX() - oldMoveTouchX);
        oldMoveTouchX = event.getX();


        if(deltaMovement < 0 ) 
        {                           
            currentView.layout((int)(currentView.getLeft()+deltaMovement),
                currentView.getTop(), (int)(currentView.getRight()+deltaMovement),
                currentView.getBottom());
        }
        else
        {
            currentView.layout((int)(currentView.getLeft()+deltaMovement),
                    currentView.getTop(), (int)(currentView.getRight()+deltaMovement),
                    currentView.getBottom());
        }
        break;


        case MotionEvent.ACTION_UP:

                leaveTouchX = event.getX();
          if (firstTouchX - 50 > leaveTouchX) {

            VF.setInAnimation(AnimationHelper.inFromRightAnimation());
            VF.setOutAnimation(AnimationHelper.outToLeftAnimation());
            VF.showNext();

          }
          else if (firstTouchX + 50 < leaveTouchX) {

            VF.setInAnimation(AnimationHelper.inFromLeftAnimation());
            VF.setOutAnimation(AnimationHelper.outToRightAnimation());
              VF.showPrevious();

          }
              break;


}
       return true;
}

public static class AnimationHelper {
      public static Animation inFromRightAnimation() {
        Animation inFromRight = new TranslateAnimation(
        Animation.RELATIVE_TO_PARENT, +1.0f,
        Animation.RELATIVE_TO_PARENT, 0.0f,
        Animation.RELATIVE_TO_PARENT, 0.0f,
        Animation.RELATIVE_TO_PARENT, 0.0f);
        inFromRight.setDuration(500);
        return inFromRight;
      }

      public static Animation outToLeftAnimation() {
        Animation outtoLeft = new TranslateAnimation(
        Animation.RELATIVE_TO_PARENT, 0.0f,
        Animation.RELATIVE_TO_PARENT, -1.0f,
        Animation.RELATIVE_TO_PARENT, 0.0f,
        Animation.RELATIVE_TO_PARENT, 0.0f);
        outtoLeft.setDuration(500);
        return outtoLeft;
      }

      // for the next movement
      public static Animation inFromLeftAnimation() {
        Animation inFromLeft = new TranslateAnimation(
        Animation.RELATIVE_TO_PARENT, -1.0f,
        Animation.RELATIVE_TO_PARENT, 0.0f,
        Animation.RELATIVE_TO_PARENT, 0.0f,
        Animation.RELATIVE_TO_PARENT, 0.0f);
        inFromLeft.setDuration(500);
        return inFromLeft;
      }

      public static Animation outToRightAnimation() {
        Animation outtoRight = new TranslateAnimation(
        Animation.RELATIVE_TO_PARENT, 0.0f,
        Animation.RELATIVE_TO_PARENT, +1.0f,
        Animation.RELATIVE_TO_PARENT, 0.0f,
        Animation.RELATIVE_TO_PARENT, 0.0f);
        outtoRight.setDuration(500);
        return outtoRight;
      }
    }

Answer 1

在视图鳍状肢中： -

机器人：layout_height = “300dp” 机器人：layout_width = “300dp”

而是替换为

android:layout_height="wrap_content"
android:layout_width="wrap_content"

删除ViewFlipper中视图之间的空格
