The problem is a Resources$NotFoundException in the tv2.settext(), i don't know why i have a TreeMap, inside the pizza title and the count. Please help!
Calling:
for (Pizza pizza : list) {
if(map.containsKey(pizza.title))
{
int i = map.get(pizza.title);
map.remove(pizza.title);
map.put(pizza.title, i++);
}
else
{
map.put(pizza.title, 1);
}
}
Pizza:开发者_StackOverflow社区
public class Pizza implements Comparable<String> {
public String title;
public int rate;
public String date;
public Bitmap picture;
public int id;
@Override
public int compareTo(String another) {
// TODO Auto-generated method stub
return this.title.compareTo(another);
}
}
Error Code:
for (Entry<String, Integer> entry : map.entrySet()) {
tv.setText(entry.getKey());
tv2.setText((Integer)entry.getValue()); //Error occures here
tv.setGravity(Gravity.LEFT);
tv2.setGravity(Gravity.RIGHT);
TableRow tr1 = new TableRow(this);
tr1.addView(tv);
tr1.addView(tv2);
tl.addView(tr1, new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
}
}
Error:
10-04 09:04:40.475: ERROR/AndroidRuntime(954): Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x1
Change tv2.setText((Integer)entry.getValue());
to
tv2.setText(entry.getValue().toString());
do like this
TableRow tr1 = new TableRow(this);
for (Entry<String, Integer> entry : map.entrySet()) {
tv.setText(entry.getKey());
tv2.setText((Integer)entry.getValue()); //Error occures here
tv.setGravity(Gravity.LEFT);
tv2.setGravity(Gravity.RIGHT);
tr1.addView(tv);
tr1.addView(tv2);
tl.addView(tr1, new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
}
}
You should use: tv2.setText(entry.getValue().toString());
Moreover, you do not need following line of code:
map.remove(pizza.title);
All you need to write is: map.put(pizza.title, i++);
becaues "put" method of the Map replaces the old value.
I don't know what you are trying to do but you're obviously not using a R.string.my_title_or_so
for setText
. The Integer
you pass to this method should be a valid (generated) id from your R
class. Or you covert the number to a string e.g. num + ""
.
tv2.setText((Integer)entry.getValue());
Parse your Integer
to String
