Question

HeyGuys，

第二天在Android Studio上，请原谅。基本上，我有一副可供用户点击的纸牌。点击后，我执行layout.addView（）;。这可行。

当我希望下一张卡与当前卡重叠时出现问题。我尝试设置负边距，仅裁剪每张图像。我缺少什么（可能很明显）？

{编辑：我的b）包含布局代码

活动：

public class NewGame extends AppCompatActivity {

RelativeLayout mRelativeLayout;
LinearLayout p1_cards;
ImageView center_deck;

private Random r = new Random();
private ArrayList<Cards> mCards;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.newgame);

    center_deck = (ImageView) findViewById(R.id.center_deck);
    mRelativeLayout = (RelativeLayout) findViewById(R.id.newgame);
    p1_cards = (LinearLayout) findViewById(R.id.p1_cards);

    mCards = new ArrayList<>();

    center_deck.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if(total_cards>0) {

                int pick1 = r.NextInt(52);

                    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(0,LinearLayout.LayoutParams.MATCH_PARENT,1f);
                    lp.setMargins(50,50,50,50);

                    ImageView cardImage = new ImageView(NewGame.this);
                    cardImage.setTag(mCards.get(pick1).getFilename());
                    cardImage.setLayoutParams(lp);
                    p1_cards.addView(cardImage);
                    int p1_current_card = getResources().getIdentifier(mCards.get(pick1).getFilename(),"drawable",getPackageName());
                    cardImage.setImageResource(p1_current_card);
                    total_cards--;

                }
                else
                {

                    Snackbar.make(mRelativeLayout,"NO MORE CARDS",Snackbar.LENGTH_LONG).show();
                }//if total cards > 0
            }
        });//button
}
}

负边缘裁切ImageView。需要替代品吗？
