活动转换从左到右滑动并向右移动动画

Question

在我的Activity过渡幻灯片中，幻灯片输入/输出动画从左到右从右向后移动，例如当前动画就像这张图片一样：

但是我想在从左到右打开活动后，从右边出来，不是从左到左，就像这张图片一样：

遗憾的是，我无法在onBackPressed()

上更改我的xml动画

ActivityMain：

Intent i = new Intent(ActivityMain.this, ActivityRobotAssistant.class);
startActivity(i);
overridePendingTransition(R.anim.pull_in_left, R.anim.push_out_right);

ActivitySecond：

public void onBackPressed() {
    super.onBackPressed();
    overridePendingTransition(R.anim.pull_in_right, R.anim.push_out_left);
}
