从ListView按钮点击打开自定义AlertDialog

Question

我在listView行内的按钮点击事件中无法成功加载自定义对话框布局。当我从listView行单击开始对话框时，它可以正常工作，但是在行内的按钮单击中，我收到一个Android.View.InflateException异常。

这是我适配器中的getView方法：

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    final ViewHolder viewHolder;

    if(convertView == null) {
        final LayoutInflater inflater= (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.planets_row, parent, false);

        // initialize the view holder
        viewHolder = new ViewHolder();
        viewHolder.zodIcon = (ImageView) convertView.findViewById(R.id.zodiacIcon);
        viewHolder.planetName = (TextView) convertView.findViewById(R.id.planetName);
        viewHolder.planetDegree = (TextView)convertView.findViewById(R.id.planetDegree);
        viewHolder.zodiacName = (TextView)convertView.findViewById(R.id.zodiacName);
        viewHolder.tvDescription = (TextView) convertView.findViewById(R.id.planetExplanation);
        viewHolder.openDetail = (Button)convertView.findViewById(R.id.planetDetailsBtn);
        convertView.setTag(viewHolder);         

        viewHolder.openDetail.setTag(position);
        viewHolder.openDetail.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Toast.makeText(mContext, viewHolder.planetName.getText().toString(), Toast.LENGTH_SHORT).show();

                 final AlertDialog.Builder dialog = new AlertDialog.Builder(mContext);
                 View view = LayoutInflater.from(mContext).inflate(R.layout.dialog_details, null);
                 dialog.setView(view);

                 TextView explan = (TextView)view.findViewById(R.id.explanationDetail);
                 Button ok = (Button)view.findViewById(R.id.ok);
                 dialog.setTitle(viewHolder.planetName.getText() + 
                         " " + viewHolder.planetDegree.getText() + " " + viewHolder.zodiacName.getText());
                 dialog.setIcon(viewHolder.zodIcon.getBackground());
                 explan.setText(descrip);
                 dialog.create();
                 ok.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View v) {
                         ((DialogInterface) dialog).dismiss();
                         return;                            
                    }
                });

                 dialog.show();

            }
        });

    } else {
        viewHolder = (ViewHolder) convertView.getTag();
    }

    planetTitle = getPlanetName(itemsList.get(position).get("planet_id"));
    planetDeg = itemsList.get(position).get("degrees")+"\u00B0";
    zodiacName = getZodiacName(itemsList.get(position).get("zodiac_id"));
    descrip = itemsList.get(position).get("content").toString();

    viewHolder.planetName.setText(planetTitle);
    viewHolder.planetDegree.setText(" " +  planetDeg);
    viewHolder.zodiacName.setText(zodiacName);
    viewHolder.tvDescription.setText(descrip);
    viewHolder.zodIcon.setBackgroundResource(getZodiacDrawable(zodiacName));

    return convertView;
}

我尝试了其他组合，例如：

LayoutInflater li = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = li.inflate(R.layout.dialog_details, null);
 dialog.setView(view);

编辑：我已经在下面包含了打印logcat

提前感谢 :)

将您的上下文转换为Activity- 格式为((Activity)mContext) - Elltz

我不认为这是上下文的问题 - 在调试时我检查了传递的内容，它是我的MainFragActivity，这个类负责一个viewpager，特别是发送到适配器的PlanetFragment。崩溃发生在“View view = ...”这一行。 - galaxigirl

为什么不直接使用一个Inflater而不是每次都创建新的呢？ - Fatih Santalu

我也尝试过这个！例如：View view = inflater.inflate（R.layout.dialog_details，null）; 这个使用了inflater用于listRow。抛出相同的错误。 - galaxigirl

我尝试了你的代码，当我在我的适配器构造函数中设置layoutInflater并使用它来填充列表行和对话框时，它可以正常工作。 - Fatih Santalu

@santalu，我按照您的建议尝试了，谢谢，但是还是出现了相同的错误。请看上面，我添加了日志。 - galaxigirl

Answer 1

尝试将您的活动传递给适配器构造函数，并将其存储在类成员中，例如上下文。然后，替换此行。

final AlertDialog.Builder dialog = new AlertDialog.Builder(mContext);

使用

final AlertDialog.Builder dialog = new AlertDialog.Builder(mActivity);

活动扩展上下文。你提出的建议似乎毫无意义。 - Simas

Answer 2

尝试更改这个：

ok.setOnClickListener(new View.OnClickListener() {...}

转换为：

ok.setOnClickListener(new DialogInterface.OnClickListener() {...}

我不知道这是否是你代码中唯一的问题，但这似乎是一个问题。
