public void makeCard( Context context, View view, String time, String startpt1, String startpt2, String endpt1, String endpt2)
{
    CardView card = new CardView(context);
    LinearLayout ll = view.findViewById(R.id.rides);
    // Set the CardView layoutParams
    int w = getResources().getDimensionPixelSize(R.dimen._270sdp);
    int h = getResources().getDimensionPixelSize(R.dimen._120sdp);
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(w, h);
    card.setForegroundGravity(17);
    card.setLayoutParams(params);


    card.setRadius(60);
    card.setCardElevation(60);

    Typeface latoregular = getResources().getFont(R.font.latoregular);
    Typeface latobold = getResources().getFont(R.font.latobold);
    // Initialize a new TextView to put in CardView

    TextView tv = new TextView(context);
    tv.setLayoutParams(params);
    SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
    try {
        Date date = format.parse(time);
        tv.setText(date.toString());
        Log.d("ASD", String.valueOf(date));
    } catch (ParseException e) {
        e.printStackTrace();
    }


    tv.setTextSize(14);
    tv.setPadding(60,40,0,0);
    tv.setTextColor(Color.parseColor("#1fb286"));
    tv.setTypeface(latobold);
    tv.setTypeface(tv.getTypeface(), Typeface.BOLD);
    card.addView(tv);
    ll.addView(card);

}

此Cardview紧贴侧面,无论我如何更改布局重力,该卡都不会移动。我可以在左侧设置填充以使其看起来居中,但在不同尺寸的屏幕上,它可能无法完美居中

您正在创建RelativeLayout.LayoutParams,并将它们用于LinearLayoutCardView(这是FrameLayout的一种)。这不太可能很好地工作。据我所知,应该使用例如LinearLayout.LayoutParams代表您要添加到View的{​​{1}}(经验法则:使用以父LinearLayout命名的LayoutParams

要使ViewGroup居中,必须以编程方式设置其CardView属性:

android:layout_gravity
