Android RelativeLayout LayoutParams setMargins（500500,0,0）无效

我正在开发一款Android游戏。我正在尝试使用边距将图像视图放置在远离屏幕左上角的位置，但它不起作用

主要活动：

@Override
protected void onCreate(Bundle savedInstanceState) {
    ...
    Display display = getWindowManager().getDefaultDisplay();
    Point size = new Point();
    display.getRealSize(size);

    RelativeLayout relativeLayout = new RelativeLayout(this);
    RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.MATCH_PARENT,
            RelativeLayout.LayoutParams.MATCH_PARENT
    );
    relativeLayout.setLayoutParams(layoutParams);
    setContentView(relativeLayout);
    gameView = new GameView(this, this, size.x, size.y);
    relativeLayout.addView(gameView);
...

和我的游戏板类：

public GameBoard (Activity activity, ...) {
    ...
    revealItemImageView = new ImageView(activity);
    revealItemImageView.setImageBitmap(bitmap);
    RelativeLayout.LayoutParams revealItemLayoutParams = new RelativeLayout.LayoutParams(
        (int)(screenHeight * 0.66), (int)(screenHeight * 0.66));
    revealItemLayoutParams.setMargins(500, 500, 0, 0);
    revealItemImageView.setLayoutParams(revealItemLayoutParams);
    activity.addContentView(revealItemImageView, revealItemLayoutParams);
    revealItemImageView.requestLayout();

但图像显示在左上角的右上角，顶部和左侧之间没有空间。为什么？

需要将视图添加到相对布局，并且需要将相对布局添加为第二个内容视图

我在它自己的项目中做了一个代码演示。这两个图像视图都具有适当的边距，并且略微重叠

下面是完整的代码

package com.zzzzzzzz.testrelativelayout;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ImageView;
import android.widget.RelativeLayout;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // layer 1
    RelativeLayout mainActivityContentViewRelativeLayout = new RelativeLayout(this);
    RelativeLayout.LayoutParams mainActivityContentViewLayoutParams = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.MATCH_PARENT,
            RelativeLayout.LayoutParams.MATCH_PARENT
    );
    mainActivityContentViewRelativeLayout.setLayoutParams(mainActivityContentViewLayoutParams);
    setContentView(mainActivityContentViewRelativeLayout);

    RelativeLayout.LayoutParams backgroundLayoutParams = new RelativeLayout.LayoutParams(100, 100);
    backgroundLayoutParams.setMargins(100, 100, 0, 0);
    ImageView backgroundView = new ImageView(this);
    backgroundView.setImageResource(R.drawable.item_baby_bottle_b);
    backgroundView.setLayoutParams(backgroundLayoutParams);
    mainActivityContentViewRelativeLayout.addView(backgroundView);

    // layer 2
    RelativeLayout secondContentViewRelativeLayout = new RelativeLayout(this);
    RelativeLayout.LayoutParams secondContentViewLayoutParams = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.MATCH_PARENT,
            RelativeLayout.LayoutParams.MATCH_PARENT
    );
    secondContentViewRelativeLayout.setLayoutParams(secondContentViewLayoutParams);
    addContentView(secondContentViewRelativeLayout, secondContentViewLayoutParams);

    RelativeLayout.LayoutParams itemLayoutParams = new RelativeLayout.LayoutParams(100, 100);
    itemLayoutParams.setMargins(150, 150, 0, 0);
    ImageView itemImageView = new ImageView(this);
    itemImageView.setImageResource(R.drawable.item_diamond_ring_a);
    itemImageView.setLayoutParams(itemLayoutParams);
    secondContentViewRelativeLayout.addView(itemImageView);

试着将其添加到

相对值yout

而不是感谢您指出这一点。再加上添加第二个内容视图正是我所需要的。我正在创建一个答案，以便有此问题的其他人可以看到完整的代码。请尝试将其添加到
