Hi!
Thank you!
For all of you, I wrote a Highscore-Class to save Highscore-Lists.
You can create a new Instance like this:
Highscore highscore = new Highscore(this); //"this" is the Context
You can add a Score to the Highscore-List with this command:
highscore.addScore("Martin", Global.score);
You do not need to test, if the score is in the Highscore-List. This
command automatically puts it in the right position, if the score is
in the Highscore-List.
If you want to test, if the score is in the Highscore-List, you can do
it like this:
highscore.inHighscore(score);
It is helpful, if you want to ask for the name just if the person is
in the Highscore-List.
You get the name of the x-th position in the Highscore like this:
highscore.getName(x);
The same for the score:
getScore(x);
Here is the Highscore-Class:
public class Highscore {
private SharedPreferences preferences;
private String names[];
private long score[];
public Highscore(Context context)
{
preferences = context.getSharedPreferences("Highscore", 0);
names = new String[10];
score = new long[10];
for (int x=0; x<10; x++)
{
names[x] = preferences.getString("name"+x, "-");
score[x] = preferences.getLong("score"+x, 0);
}
}
public String getName(int x)
{
//get the name of the x-th position in the Highscore-List
return names[x];
}
public long getScore(int x)
{
//get the score of the x-th position in the Highscore-List
return score[x];
}
public boolean inHighscore(long score)
{
//test, if the score is in the Highscore-List
int position;
for (position=0; position<10&&this.score[position]>score;
position+
+);
if (position==10) return false;
return true;
}
public boolean addScore(String name, long score)
{
//add the score with the name to the Highscore-List
int position;
for (position=0; position<10&&this.score[position]>score;
position+
+);
if (position==10) return false;
for (int x=9; x>position; x--)
{
names[x]=names[x-1];
this.score[x]=this.score[x-1];
}
this.names[position] = new String(name);
this.score[position] = score;
SharedPreferences.Editor editor = preferences.edit();
for (int x=0; x<10; x++)
{
editor.putString("name"+x, this.names[x]);
editor.putLong("score"+x, this.score[x]);
}
editor.commit();
return true;
}
}
