Question

我无法在 listView 行中点击按钮内部来扩展我的自定义对话框布局。当我从listView行点击启动对话框时，它工作正常，但是从行内的按钮点击我得到 Android.View.InflateException 。

以下是适配器的 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);

修改：我已在 print logcat 下面加入

Answer 1

尝试在适配器构造函数中传递您的活动，并将其存储在类成员中，就像您的上下文一样。然后，替换此行

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

与

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

Answer 2

尝试更改此内容：

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

到此：

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

我不知道这是否是您代码中唯一的问题，但这似乎是一个问题。

从ListView按钮打开自定义AlertDialog按钮
