尝试将视图动态添加到线性布局android时获取java.lang.RuntimeException

Question

尝试在 android 中向线性布局添加视图时出现以下崩溃。

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.q8car.andriod.activity/com.technivance.q8car.view.FilterItemsActivity}: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

我的代码如下

ArrayList<ColorResponse> colors = Q8CarDBManager.getAllColors(FilterItemsActivity.this);
        addColor(-1, null, getString(R.string.no_color));

        if (colors != null && colors.size() > 0) {

            for (int i = 0; i < colors.size(); i++) {

                addColor(colors.get(i).getId(), colors.get(i).getHexaCode(), colors.get(i).getName());
            }
        }

        updateSelectedColor(-1);

而addColor方法如下

private void addColor(final int colorId, final String colorHexa, final String title) {

        int padding = (int) getResources().getDimension(R.dimen.small_margin);

        if (inflatedView == null) {

            inflatedView = getLayoutInflater().inflate(R.layout.item_color, null);
        }

        if (mLayoutParam == null) {

            mLayoutParam = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
            mLayoutParam.setMargins(0, 0, padding, 0);
        }

        inflatedView.setLayoutParams(mLayoutParam);

        ImageView colorImage = (ImageView)inflatedView.findViewById(R.id.color_image);
        TextView colorTitle = (TextView)inflatedView.findViewById(R.id.color_title);

        int color = -2;
        if (PhoneUtils.isEmpty(colorHexa) == false)
            color = Color.parseColor("#" + colorHexa);

        BitmapDrawable drawable = ImageManager.getInstance().getRoundedShapeWithColor(this, R.drawable.no_color, color , true);
        colorImage.setImageDrawable(drawable);

        colorImage.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {

                mColorId = colorId;
                updateSelectedColor(colorId);
            }
        });
        colorTitle.setText(title);

//      if(inflatedView.getParent()!=null)
//          ((ViewGroup)inflatedView.getParent()).removeView(inflatedView);

        inflatedView.setId(colorId);
        mColorsImageViews.put(colorId, colorImage);
        mColorsLayout.addView(inflatedView);
    }

请不要这样，当我每次创建膨胀布局时都会花费很多时间。

这是完整的堆栈跟踪

造成崩溃的方法是addColor [mColorsLayout.addView(mColorInflatedView);];

Answer 1

异常消息几乎可以告诉您问题出在哪里。当您已经将其附加到mColorsLayout 时，您的inflatedView 似乎只能不是null，然后您尝试再次附加它。您必须分别为每个视图充气，而不是在类级别为每种颜色声明一个 View 对象。
