layoutinflater问题

Question

在我的应用程序中，我希望在单击警告对话框时显示透明面板ok按钮。在mapview.i的ontap方法中显示了对话框，为创意透明面板创建了单独的类，现在按下Ok按钮点击该类。

在膨胀时我正在获得由于未找到类异常引​​起的异常布局缓冲器异常。

这是我的代码

@Override
    protected boolean onTap(int i) {
        final Animation animShow;
        final Animation animHide;
        AlertDialog.Builder builder = null;

        OverlayItem item=getItem(i);
        builder=new AlertDialog.Builder(mcontext);
        builder.setTitle(item.getTitle());
        animShow = AnimationUtils.loadAnimation(FindFishActivity.this, R.anim.popup_show);
        animHide = AnimationUtils.loadAnimation( FindFishActivity.this, R.anim.popup_hide);
        builder.setPositiveButton("Show Info",new DialogInterface.OnClickListener() {

            public void onClick(DialogInterface dialog, int which) {
                onShowInfo();

            }

            public void onShowInfo() {
                LayoutInflater inflater=LayoutInflater.from(FindFishActivity.this);
                View view=inflater.inflate(R.layout.tutorial5,(ViewGroup)findViewById(R.id.linearlayoutID));
                transparentPanel=(TransparentPanel)view.findViewById(R.id.popup_window);
                transparentPanel.setVisibility(View.VISIBLE);
                transparentPanel.startAnimation(animShow);

            }
        });
        builder.show();


        return true;
    }

我的transperantpanel类，它是从线性布局

扩展而来的

公共类TransparentPanel扩展了LinearLayout {     private Paint innerPaint，borderPaint;

public TransparentPanel(Context context, AttributeSet attrs) {
    super(context, attrs);
    init();
}

public TransparentPanel(Context context) {
    super(context);
    init();
}

private void init() {
    innerPaint = new Paint();
    innerPaint.setARGB(225, 75, 75, 75); //gray
    innerPaint.setAntiAlias(true);

    borderPaint = new Paint();
    borderPaint.setARGB(255, 255, 255, 255);
    borderPaint.setAntiAlias(true);
    borderPaint.setStyle(Style.STROKE);
    borderPaint.setStrokeWidth(2);
}

public void setInnerPaint(Paint innerPaint) {
    this.innerPaint = innerPaint;
}

public void setBorderPaint(Paint borderPaint) {
    this.borderPaint = borderPaint;
}

@Override
protected void dispatchDraw(Canvas canvas) {

    RectF drawRect = new RectF();
    drawRect.set(0,0, getMeasuredWidth(), getMeasuredHeight());

    canvas.drawRoundRect(drawRect, 5, 5, innerPaint);
    canvas.drawRoundRect(drawRect, 5, 5, borderPaint);

    super.dispatchDraw(canvas);
}

和我的xml文件
