Question

我正在使用TranslateAnimation的app，但我想将TranslateAnimation转换为开始位置。

    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);

        setContentView(R.layout.imageviewactivity);

        TranslateAnimation toptranslateanimation = new TranslateAnimation(0, 0, tempBar,
                    scanner_image.getHeight() - 50);
        toptranslateanimation.setDuration(4000);
            toptranslateanimation.setAnimationListener(this);
                scanning_bar.setAnimation(toptranslateanimation);
}

Answer 1

尝试使用此代码

<name>: initial

Answer 2

使用Interpolator for Like，

package com.example.android;

import android.view.animation.Interpolator;

public class ReverseInterpolator implements Interpolator {
    @Override
    public float getInterpolation(float paramFloat) {
        return Math.abs(paramFloat -1f);
    }
}

然后在动画上你可以设置新的插补器：

toptranslateanimation.setInterpolator(new ReverseInterpolator());

TranslateAnimation处于反向位置？
