安卓view 的显示问题(具体描述请看代码

半吊子新手想写一个游戏里面物品栏一样的东西，结果在画格子的时候遇到了问题。。。求大神点醒我。

这是view的代码，将此代码直接放入mainactivity主函数，view的显示没有问题
LayoutInflater layoutInflater = LayoutInflater.from(mcontext);
final View mview = layoutInflater.inflate(R.layout.inventory, null);
RelativeLayout mRalativeLayout = (RelativeLayout) findViewById(R.id.mainRalativeLayout);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(-1, -1);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
mRalativeLayout.addView(mview);
mview.setLayoutParams(layoutParams);

但是将上述代码放入点击事件之后，我试过了点击事件，还有handler，也试过了直接在点击事件里面用setContentView加载布局。view之中的小方块都不能显示了。

以下是相关的代码

public class InventoryView extends GridLayout {
    public int cardWidth;
    public InventoryView(Context context) {
        super(context);
        set();
    }

    public InventoryView(Context context, AttributeSet attrs) {
        super(context, attrs);
        set();
    }

    public InventoryView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        set();
    }

    private Cell[][] cellsMap = new Cell[9][9];

    private void set() {
        setBackgroundColor(0xffbbada0);
        setColumnCount(9);
    }

    public void addCell(int CellWidth, int CellHeight) {
        Cell cell;

        int ID = 0;
        for (int i = 0; i < 9; i++) {
            for (int k = 0; k < 9; k++) {
                ID++;
                cell = new Cell(getContext());
                cell.setCellID(ID);
                final String finalID = ID + "";
                cell.setOnClickListener(new OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Log.v("ID=", finalID);
                    }
                });
                addView(cell, CellWidth, CellHeight);

                cellsMap[i][k] = cell;
            }
        }
    }

    public int getCardWidth() {
        return cardWidth;
    }

    public void setCardWidth(int cardWidth) {
        this.cardWidth = cardWidth;
    }

    protected void onSizeChanged(int w, int h, int oldw, int oldh) {
        super.onSizeChanged(w, h, oldw, oldh);

        cardWidth = (Math.min(w, h) - 10) / 9;

        addCell(cardWidth, cardWidth);
    }
}

public class Cell extends FrameLayout {
    private TextView textView;
    private int CellID;

    public Cell(Context context) {
        super(context);

        CellID = -1;
        textView = new TextView(getContext());
        textView.setTextSize(16);
        textView.setGravity(Gravity.CENTER);
        textView.setBackgroundColor(0x33ffffff);

        LayoutParams lp = new LayoutParams(-1,-1);
        lp.setMargins(5,5,0,0);
        addView(textView,lp);
    }

    public TextView getTextView() {
        return textView;
    }

    public void setTextView(TextView textView) {
        this.textView = textView;
    }

    public int getCellID() {
        return CellID;
    }

    public void setCellID(int cellID) {
        CellID = cellID;
    }
}

mRalativeLayout.addView(mview);
mview.setLayoutParams(layoutParams);
这两句代码是不是该交换下位置？
