java - 为Android中的一组对象设置动画

Question

我有几个 TextView 对象，我需要用相同 Animation 设置动画。

我这样做的方式看起来不对，因为我一次只能为每个对象设置Animation

@Override
    public void onClick(View v) {

    Animation hideLeftBar, showLeftBar;

    hideLeftBar = new TranslateAnimation(195, 0, 0, 0);
    hideLeftBar.setDuration(1000);
    hideLeftBar.setFillAfter(true);

    showLeftBar = new TranslateAnimation(0, 195, 0, 0);
    showLeftBar.setDuration(1000);
    showLeftBar.setFillAfter(true);

    switch(v.getId())
    {
    case R.id.btGMG:

        if(img_GMG.getAlpha() == (float) 0.3)
        {
            img_GMG.setAlpha((float) 1);
            imgLeftBar.startAnimation(showLeftBar);
            txtRS.startAnimation(showLeftBar);
            txtST.startAnimation(showLeftBar);
            txtTR.startAnimation(showLeftBar);
            txtI1.startAnimation(showLeftBar);
            txtI2.startAnimation(showLeftBar);
            txtI3.startAnimation(showLeftBar);
            txtP1.startAnimation(showLeftBar);
            txtP2.startAnimation(showLeftBar);
            txtP3.startAnimation(showLeftBar);
            txtS1.startAnimation(showLeftBar);
            txtS2.startAnimation(showLeftBar);
            txtS3.startAnimation(showLeftBar);
            txtFP1.startAnimation(showLeftBar);
            txtFP2.startAnimation(showLeftBar);
            txtFP3.startAnimation(showLeftBar);
            textIndutive.startAnimation(showLeftBar);
            textCapacitive.startAnimation(showLeftBar);


        }
        else
        {
            img_GMG.setAlpha((float) 0.3);
            imgLeftBar.startAnimation(hideLeftBar);
            txtRS.startAnimation(hideLeftBar);
            txtST.startAnimation(hideLeftBar);
            txtTR.startAnimation(hideLeftBar);
            txtI1.startAnimation(hideLeftBar);
            txtI2.startAnimation(hideLeftBar);
            txtI3.startAnimation(hideLeftBar);
            txtP1.startAnimation(hideLeftBar);
            txtP2.startAnimation(hideLeftBar);
            txtP3.startAnimation(hideLeftBar);
            txtS1.startAnimation(hideLeftBar);
            txtS2.startAnimation(hideLeftBar);
            txtS3.startAnimation(hideLeftBar);
            txtFP1.startAnimation(hideLeftBar);
            txtFP2.startAnimation(hideLeftBar);
            txtFP3.startAnimation(hideLeftBar);
            textIndutive.startAnimation(hideLeftBar);
            textCapacitive.startAnimation(hideLeftBar);
        }


        break;
    }

}

我怎样才能减少这个？我应该以编程方式还是使用XML资源？

你应该使用 AnimatorSet .它有一个 playTogether() function将同时播放所有动画。看一个很好的例子here .
