Question

我有一个包含天气图标的ttf文件。我想使用这些字体在listview中为每日临时创建天气图标。我已经设置好了，我在listview中也获得了图标，但是在8个listview项目中只有一个。另外，当我向上和向下滚动时，它只刷新到一个地方，而不是到处都是。我正在为我的列表视图发布getview方法，我在其中设置所有数据。

        public View getView(int position, View convertView, ViewGroup parent) {

        ViewHolder holder;

        if(convertView==null){
            convertView = LayoutInflater.from(getContext()).inflate(R.layout.activity_whether_list_style, null);
            holder = new ViewHolder();
            holder.description = (TextView) convertView.findViewById(R.id.description);
            holder.weatherIcon = (TextView) convertView.findViewById(R.id.weather_iconT);
            holder.maxTemp = (TextView) convertView.findViewById(R.id.max_temp);
            holder.minTemp = (TextView) convertView.findViewById(R.id.min_temp);
            holder.dayName = (TextView) convertView.findViewById(R.id.day);
            convertView.setTag(holder);
        }

        else  holder = (ViewHolder)convertView.getTag();

        Daily daily = dailyTest.get(position);
        holder.description.setText(daily.getDescription());
        holder.dayName.setText(daily.getFormattedTime());

        Typeface typeface = Typeface.createFromAsset(getAssets(), "Weather&Time.ttf" );
        holder.weatherIcon.setTypeface(typeface);
        holder.weatherIcon.setText(daily.getWeatherIconString());


        //for two digit temp format.. adding 0 for single digits.
        int maxtemp = (daily.getMaxTemp()-32)*5/9;
        if(maxtemp<10){
            holder.maxTemp.setText("0"+ maxtemp);
        } else holder.maxTemp.setText(""+ maxtemp);

        int mintemp = (daily.getMinTemp()-32)*5/9;
        if(mintemp<10) {
            holder.minTemp.setText("0"+ mintemp);

        } else holder.minTemp.setText(""+ mintemp);


        return convertView;
    }

Answer 1

请粘贴您的Viewholder类代码。

如果你提到过静态Textview，请从中删除静态关键字。

Answer 2

您没有将上下文传递给createFromAsset字体，将上下文传递给createFromAsset并尝试此代码。

 if(convertView==null){
            convertView = LayoutInflater.from(getContext()).inflate(R.layout.activity_whether_list_style, null);
            holder = new ViewHolder();
            holder.description = (TextView) convertView.findViewById(R.id.description);
            holder.weatherIcon = (TextView) convertView.findViewById(R.id.weather_iconT);
            holder.maxTemp = (TextView) convertView.findViewById(R.id.max_temp);
            holder.minTemp = (TextView) convertView.findViewById(R.id.min_temp);
            holder.dayName = (TextView) convertView.findViewById(R.id.day);
            convertView.setTag(holder);
        }

        else  holder = (ViewHolder)convertView.getTag();

        Daily daily = dailyTest.get(position);
        holder.description.setText(daily.getDescription());
        holder.dayName.setText(daily.getFormattedTime());

        Typeface typeface = Typeface.createFromAsset(getContext().getAssets(), "Weather&Time.ttf" );
        holder.weatherIcon.setTypeface(typeface);
        holder.weatherIcon.setText(daily.getWeatherIconString());


        //for two digit temp format.. adding 0 for single digits.
        int maxtemp = (daily.getMaxTemp()-32)*5/9;
        if(maxtemp<10){
            holder.maxTemp.setText("0"+ maxtemp);
        } else holder.maxTemp.setText(""+ maxtemp);

        int mintemp = (daily.getMinTemp()-32)*5/9;
        if(mintemp<10) {
            holder.minTemp.setText("0"+ mintemp);

        } else holder.minTemp.setText(""+ mintemp);


        return convertView;
    }

TTF字体到图标在listview android中不起作用
