我正在尝试将动态文本视图添加到列表视图项目。文本视图可以是 1-2 或更多,具体取决于我成功添加文本视图的数据,但问题是文本视图在滚动时重复。
我每次都在循环中创建 textview 的新对象。我知道 android 尝试重用现有视图但我每次都必须添加新视图的问题。
这是我在自定义适配器中的代码:
public class ViewHolder {
TextView text1;
LinearLayout linearLayout;
TextView t;
TextView t1;
}
获取视图方法
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.two_item_icon_text, null);
holder = new ViewHolder();
holder.text1 = (TextView) convertView.findViewById(R.id.text1);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.linearLayout = (LinearLayout) convertView.findViewById(R.id.lin_lay_dynamic);
holder.text1.setText("" + DATA1[position]);
String tmp, dateparsed;
dateparsed = DATA1[position].substring(0, DATA1[position].indexOf(":"));
for (int x = 0; x < calendareventholder1.size(); x++) {
objHolder = (CalendarEventHolder) calendareventholder1.get(x);
if (objHolder.opendate.equals(displaydate[current])) {
tmp = objHolder.dtstarttime.toString().substring(0, objHolder.dtstarttime.toString().indexOf(":"));
if (Integer.parseInt(tmp) >= Integer.parseInt(dateparsed) && Integer.parseInt(tmp) < Integer.parseInt(dateparsed) + 1) {
holder.t = new TextView(convertView.getContext());
holder.t.setText(":-d ");
holder.t.setOnClickListener(this);
if (Common.isChildSessionAlerted(String.valueOf(objHolder.id), getApplicationContext(), object1)) {
holder.t.setText(holder.t.getText() + objHolder.dtstarttime + " " + objHolder.dtendtime + " :-a");
} else {
holder.t.setText(holder.t.getText() + objHolder.dtstarttime + " " + objHolder.dtendtime);
}
holder.t.setTag(objHolder.id);
holder.t.setTextSize(Common.getPreferenceInt(getApplicationContext(), Common.PREF_FONT_SIZE, 10));
holder.t.setTextColor(Color.BLACK);
holder.t.setText(getSmiledText(ScheduleActivity.this,
holder.t.getText().toString()));
holder.linearLayout.addView(holder.t);
holder.t1 = new TextView(convertView.getContext());
holder.t1.setOnClickListener(this);
holder.t1.setText(objHolder.title);
holder.t1.setTag(objHolder.id);
holder.t1.setTextSize(Common.getPreferenceInt(getApplicationContext(), Common.PREF_FONT_SIZE, 10));
holder.t1.setTextColor(Color.BLACK);
holder.linearLayout.addView(holder.t1);
}
}
}
return convertView;
}
