不同的文字颜色为每类对象？ [英] Different text color for each class object?
本文介绍了不同的文字颜色为每类对象？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在做某种游戏得分的追踪者。这里的应用程序目前是如何工作的：
I'm making some kind of "game score tracker". Here's how the app currently works:
- 用户键入一个名称的EditText，然后单击确定按钮，增加了球员。
- 在用户完成添加新的球员，他presses开始游戏按钮和一个新的活动打开。
- 玩家加入到Parcelable额外并被带到下一个活动。
- 在接下来的活动中，用户有一个旋转器的EditText和+， - 按键。之后，用户选择从离心器在一定分数一定播放机，类型，然后任一个+或 - ，一个新的TextView将出现包含播放器名称和评分
例如：如果有3名球员詹姆斯，约翰和罗伯特。然后，用户增加了5分詹姆斯10分，约翰和15分罗伯特。这是TextViews怎么会是这样的：
Example: If there are 3 Players "James, John and Robert". The user then adds 5 points to James, 10 points to John and 15 points to Robert. This is how TextViews will look like:
詹姆斯5
约翰福音10
15罗伯特
然后，如果用户将再次做完全相同的事情，会出现这种情况：
Then if user will do the exactly same thing again, this will happen:
詹姆斯5
约翰福音10
15罗伯特
10詹姆斯
约翰福音20
30罗伯特
因此，大家可以看到，我不要让每个玩家在同一TextView的，但我一直将他们（我希望如此，我希望用户能够看到他的行动，当他点击 - 和+时但有没有以某种方式为每个用户设置颜色的方法举例：？？詹姆斯会是蓝色的，约翰将是红色和罗伯特将是绿色的我如何pre-确定每个玩家的TextView的颜色
So as you can see, I don't keep the same TextView for each player but I keep adding them (I do want that, I want the user to be able to see his actions, when he clicked - and when +. But is there a way to somehow set a color for each user? Example: James will be blue, John will be red and Robert will be green. How do I pre-determine the color of each Player's TextView?
Player类：
public static class Player implements Parcelable{
String name;
int score;
@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(score);
dest.writeString(name);
}
public Player(Parcel source){
score = source.readInt();
name = source.readString();
}
public Player(){
}
public static final Parcelable.Creator<Player> CREATOR = new Parcelable.Creator<Novaigra.Player>() {
@Override
public Player createFromParcel(Parcel source) {
return new Player(source);
}
@Override
public Player[] newArray(int size) {
return new Player[size];
}
};
}
我可以添加某种调色板到活动正在增加球员时，使用户可以pre-确定一种颜色的东西？
Can I add some kind of color palette to the activity when players are being added so that a user can pre-determine a color or something?

下面是一个颜色选择器，Android的犯规有一个内置的，随意修改它以您的需求。
here is a color picker, android doesnt have one built in, feel free to modify it to your needs

mListener.colorChanged(mKey, color);
dismiss();
}
};
setContentView(new ColorPickerView(getContext(), l, mInitialColor,
mDefaultColor));
setTitle("Pick Text Color");
}
}
然后当你从colorchangelistener整型的颜色，当他们选择，或者如果它使用默认或任何INT保存到播放器
then when you get the int color from the colorchangelistener when they pick or if it uses the default or whatever save the int into the player
编辑：我想我剥默认了这一个，因为它不跨设备扩展太好了，这是我不能记住，你可能会瓦纳经历，并检查，它的工作原理虽然
你需要一个按钮或东西触发颜色选择器
i think i stripped the default out of this one because it doesnt scale too well across devices, something i cant remember, you might wana go through it and check, it works though you need a button or something to trigger the color picker
在您的活动
import "your package name".ColorPickerDialog
然后让你的活动
implement OnColorChangeListener
然后在按钮的颜色选择器上来
then in the button for the color picker to come up
ColorPickerDialog color = new ColorPickerDialog(this,this, "picker",Color.BLACK,Color.WHITE);
color.show();
您应该能够覆盖，因为你实现OnColorChangeListener方法是
the method you should be able to override because you implemented OnColorChangeListener is
@Override
public void colorChanged(String key, int color) {
// TODO Auto-generated method stub
paint.setColor(color);
}
我只是有paint.setColor（）在那里，但你可以保存INT颜色女巫颜色选择器中选择您的播放器类的颜色，并用它在你的textviews文本颜色。
i just have paint.setColor() in there but you can save the int color witch is the color selected in the color picker to your Player class and use it for the text color in your textviews.
