Question

美好的一天，我有一个以编程方式放置在SurfaceView左下角的视图，我想要的是当点击一个按钮时，视图滑出屏幕并滑回，但似乎没有发生在动画。这是我的代码，我将把相关部分：

layout.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/my_Info"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#6444"
    android:orientation="vertical"
    android:visibility="visible" >


        <TextView
            android:id="@+id/name_id"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="16dp"
            android:text="name" />

        <TextView
            android:id="@+id/medium_id"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="16dp"
            android:text="med"/>

        <TextView
            android:id="@+id/dimensions_id"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="16dp"
            android:text="dimen" />


</LinearLayout>

定位视图：

RelativeLayout.param = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, 240);
                            param.leftMargin = 0;

                            inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                            view = inflater.inflate(R.layout.my_info, null);
                            mylayout = (LinearLayout)view.findViewById(R.id.gallery_Info_root_id);  //what i want to animate

                            view.setLayoutParams(param);

                             param.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
                             param.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);

                             view.getLayoutParams().width = 380;

                            RelativeLayout lContainerLayout = new RelativeLayout(VideoPlayback.this);
                            lContainerLayout.setLayoutParams(new RelativeLayout.LayoutParams( LayoutParams.MATCH_PARENT , LayoutParams.MATCH_PARENT ));

                            lContainerLayout.addView(view);
                            addContentView(lContainerLayout, new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));

滑入并滑出动画：

    private void slideInView(){

    Animation slidein = new MyTranslateAnimation(mylayout, -mylayout.getWidth(), 0, 0, 0);
    slidein.setDuration(animationDuration);
    slidein.setInterpolator(interpolator);      
    mylayout.startAnimation(slidein);

}

private void slideOutView(){

    Animation slidein = new MyTranslateAnimation(mylayout, 0, -mylayout.getWidth(), 0, 0);
    slidein.setDuration(animationDuration);
    slidein.setInterpolator(interpolator);
    mylayout.startAnimation(slidein);

}

我从here获得的MyTranslateAnimation

public class MyTranslateAnimation extends Animation {

  private View view;
  private final float fromX;
  private final float toX;
  private final float fromY;
  private final float toY;


    public MyTranslateAnimation(View v, float fromX, float toX, float fromY, float toY) {
        view = v;
        this.fromX = fromX;
        this.toX = toX;
        this.fromY = fromY;
        this.toY = toY;
        setDuration(500);
    }

    @Override
    protected void applyTransformation(float interpolatedTime, Transformation t) {
        float x = (toX-fromX) * interpolatedTime + fromX;
        float y = (toY - fromY) * interpolatedTime + fromY;
        RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)view.getLayoutParams();
        params.setMargins((int)x, (int)y, 0, 0);
        view.requestLayout();
    }
}

任何人都可以发现我做错的事吗？因为我似乎无法理解为什么我不能将“mylayout”滑入和滑出。提前谢谢。
