android - 在 "end of translate animation"和布局重新定位之间，有一个意外的 "jump"。如何避免？

Question

所以我的应用程序遇到了下一个问题。我正在为我的布局使用 TranslateAnimation，在它结束后我为我的布局设置了新的 l、t、b、r，以便在物理上替换它。这是代码:

package com.Borislav_Nazarski_SM;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.animation.AccelerateInterpolator;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.Animation;
import android.view.animation.TranslateAnimation;
import android.widget.ImageView;
import android.widget.RelativeLayout;


public class main extends Activity implements OnClickListener,AnimationListener {

    RelativeLayout L;
    ImageView imageView4;
    Animation inFromLeftAnimation,inFromRightAnimation;


    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);


        L = (RelativeLayout)this.findViewById(R.id.mainlayout);
        imageView4 = (ImageView)this.findViewById(R.id.imageView4);
        imageView4.setOnClickListener(this);
        //animation that move the layout from top to 202px
        inFromLeftAnimation = new TranslateAnimation(0,0,0,202);
        inFromLeftAnimation.setDuration(12500);
        inFromLeftAnimation.setInterpolator(new AccelerateInterpolator());
        inFromLeftAnimation.setFillEnabled(true);
        inFromLeftAnimation.setFillAfter(true);
        inFromLeftAnimation.setFillBefore(false);
        inFromLeftAnimation.setAnimationListener(this);
          //animation that move the layout back
        inFromRightAnimation = new TranslateAnimation(0,0,202,0);
        inFromRightAnimation.setDuration(12500);
        inFromRightAnimation.setInterpolator(new AccelerateInterpolator());
        inFromRightAnimation.setFillEnabled(true);
        inFromRightAnimation.setFillBefore(false);
        inFromRightAnimation.setFillAfter(true);
        inFromRightAnimation.setAnimationListener(this);
    }

    public void onClick(View v) {
        if(v==imageView4)
        {

            if(v.isSelected())
            {
                v.setSelected(false);
                L.clearAnimation();
        L.startAnimation(inFromRightAnimation);
        }
            else
            {
                v.setSelected(true);
                L.clearAnimation();
                L.startAnimation(inFromLeftAnimation);
            }
        }

   }
    public void onAnimationEnd(Animation animation) {
        if(animation==inFromLeftAnimation){

            L.layout(0,0,800,606);

        }
        if(animation==inFromRightAnimation){

            L.layout(0,-202,800,404);

        }
    }
    public void onAnimationRepeat(Animation animation) {
        // TODO Auto-generated method stub

    }
    public void onAnimationStart(Animation animation) {
        // TODO Auto-generated method stub

    }
    }

这是布局 xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:background="#00FF00" android:orientation="horizontal" android:id="@+id/mainlayout" android:layout_height="606px" android:layout_gravity="bottom">
    <ImageView android:src="@drawable/icon" android:id="@+id/imageView1" android:layout_width="130px" android:layout_height="180px" android:layout_alignParentLeft="true" android:layout_alignParentTop="true"></ImageView>
    <ImageView android:src="@drawable/icon" android:id="@+id/imageView2" android:layout_width="130px" android:layout_height="180px" android:layout_below="@+id/imageView3"></ImageView>
    <ImageView android:src="@drawable/icon" android:id="@+id/imageView3" android:layout_centerVertical="true" android:layout_width="130px" android:layout_height="180px" android:layout_below="@+id/imageView1"></ImageView>
    <ImageView android:src="@drawable/icon" android:id="@+id/imageView4" android:clickable="true" android:layout_width="130px" android:layout_height="180px" android:layout_toRightOf="@+id/imageView3" android:layout_below="@+id/imageButton1"></ImageView>
    <ImageButton android:id="@+id/imageButton1" android:src="@drawable/icon" android:layout_width="130px" android:layout_height="180px" android:layout_toRightOf="@+id/imageView1" android:layout_above="@+id/imageView3"></ImageButton>
    <ImageButton android:id="@+id/imageButton2" android:src="@drawable/icon" android:layout_width="130px" android:layout_height="180px" android:layout_toRightOf="@+id/imageView2" android:layout_below="@+id/imageView4"></ImageButton>
</RelativeLayout>

所以问题是在动画到达结束后 - 根据动画有向下或向上的“跳跃” - 可能与我使用的定位有关 L.layout(... 不起作用。请,帮助。提前致谢

这是 animationListeners 的一个已知错误。作为一种解决方法，您必须将 View 子类化并在那里覆盖 onAnimationEnd 。另见 android animation is not finished in onAnimationEnd
