我正在研究自定义步进器.

一切都很好.

我现在要做的是在填充当前步骤的同时为步进器设置动画.

这张图片显示了我的想法：

设置行,标题和图标src的颜色时,这是我的代码：

private void DrawStepper(int position) {

switch (position) {

case 0:

imgStepShipper.setImageResource(R.drawable.ic_current_step);

txtStepShipper.setTextColor(getResources().getColor(R.color.colorPrimary));

line.setBackgroundColor(getResources().getColor(R.color.colorDarkWhite));

imgStepConsignee.setImageResource(R.drawable.ic_unselected_step);

txtStepConsignee.setTextColor(getResources().getColor(R.color.colorDarkSuperWhite));

line2.setBackgroundColor(getResources().getColor(R.color.colorDarkWhite));

imgStepShipment.setImageResource(R.drawable.ic_unselected_step);

txtStepShipment.setTextColor(getResources().getColor(R.color.colorDarkSuperWhite));

line3.setBackgroundColor(getResources().getColor(R.color.colorDarkWhite));

imgStepCharges.setImageResource(R.drawable.ic_unselected_step);

txtStepCharges.setTextColor(getResources().getColor(R.color.colorDarkSuperWhite));

break;

case 1:

imgStepShipper.setImageResource(R.drawable.ic_done_step);

txtStepShipper.setTextColor(getResources().getColor(R.color.colorPrimary));

line.setBackgroundColor(getResources().getColor(R.color.colorPrimary));

imgStepConsignee.setImageResource(R.drawable.ic_current_step);

txtStepConsignee.setTextColor(getResources().getColor(R.color.colorPrimary));

line2.setBackgroundColor(getResources().getColor(R.color.colorDarkWhite));

imgStepShipment.setImageResource(R.drawable.ic_unselected_step);

txtStepShipment.setTextColor(getResources().getColor(R.color.colorDarkSuperWhite));

line3.setBackgroundColor(getResources().getColor(R.color.colorDarkWhite));

imgStepCharges.setImageResource(R.drawable.ic_unselected_step);

txtStepCharges.setTextColor(getResources().getColor(R.color.colorDarkSuperWhite));

break;

case 2:

imgStepShipper.setImageResource(R.drawable.ic_done_step);

txtStepShipper.setTextColor(getResources().getColor(R.color.colorPrimary));

line.setBackgroundColor(getResources().getColor(R.color.colorPrimary));

imgStepConsignee.setImageResource(R.drawable.ic_done_step);

txtStepConsignee.setTextColor(getResources().getColor(R.color.colorPrimary));

line2.setBackgroundColor(getResources().getColor(R.color.colorPrimary));

imgStepShipment.setImageResource(R.drawable.ic_current_step);

txtStepShipment.setTextColor(getResources().getColor(R.color.colorPrimary));

line3.setBackgroundColor(getResources().getColor(R.color.colorDarkWhite));

imgStepCharges.setImageResource(R.drawable.ic_unselected_step);

txtStepCharges.setTextColor(getResources().getColor(R.color.colorDarkSuperWhite));

break;

case 3:

imgStepShipper.setImageResource(R.drawable.ic_done_step);

txtStepShipper.setTextColor(getResources().getColor(R.color.colorPrimary));

line.setBackgroundColor(getResources().getColor(R.color.colorPrimary));

imgStepConsignee.setImageResource(R.drawable.ic_done_step);

txtStepConsignee.setTextColor(getResources().getColor(R.color.colorPrimary));

line2.setBackgroundColor(getResources().getColor(R.color.colorPrimary));

imgStepShipment.setImageResource(R.drawable.ic_done_step);

txtStepShipment.setTextColor(getResources().getColor(R.color.colorPrimary));

line3.setBackgroundColor(getResources().getColor(R.color.colorPrimary));

imgStepCharges.setImageResource(R.drawable.ic_current_step);

txtStepCharges.setTextColor(getResources().getColor(R.color.colorPrimary));

break;

}

}

位置是当前步骤.

这是我的用户界面：

正如我所说的,每次从一个步骤移动到另一个步骤时,我想要为该线条设置动画.

谢谢 ：)
