安卓联系人名称为数字空格时显示变化
2013 年 9 月 17 日 安卓联系人名称为数字空格时显示变化无评论
安卓联系人会根据输入的名称判断姓氏、姓名等，当输入数字时被当作西文姓名格式，所以会出现后边的数字倒置的情况，在中文环境下，输入如”1 2 3″的姓名会变为”321″。
安卓在分割联系人名称时做了五种区分，WESTERN/CHINESE/JAPANESE/KOREAN/UNDEFINED，具体定义在frameworks/base/core/java/android/provider/ContactsContract.java中，如下所示：
public interface FullNameStyle {
public static final int UNDEFINED = 0;
public static final int WESTERN = 1;
/**
* Used if the name is written in Hanzi/Kanji/Hanja and we could not determine
* which specific language it belongs to: Chinese, Japanese or Korean.
*/
public static final int CJK = 2;
public static final int CHINESE = 3;
public static final int JAPANESE = 4;
public static final int KOREAN = 5;
}
public static final int UNDEFINED = 0;
public static final int WESTERN = 1;
/**
* Used if the name is written in Hanzi/Kanji/Hanja and we could not determine
* which specific language it belongs to: Chinese, Japanese or Korean.
*/
public static final int CJK = 2;
public static final int CHINESE = 3;
public static final int JAPANESE = 4;
public static final int KOREAN = 5;
}
分割的控制在ContactsProvider中，packages/providers/ContactsProvider/src/com/android/providers/contacts/NameSplitter.java
如所示：
/**
* Makes the best guess at the expected full name style based on the character set
* used in the supplied name.
*/
private void guessFullNameStyle(NameSplitter.Name name) {
if (name.fullNameStyle != FullNameStyle.UNDEFINED) {
return;
}
int bestGuess = guessFullNameStyle(name.givenNames);
// A mix of Hanzi and latin chars are common in China, so we have to go through all names
// if the name is not JANPANESE or KOREAN.
if (bestGuess != FullNameStyle.UNDEFINED && bestGuess != FullNameStyle.CJK
&& bestGuess != FullNameStyle.WESTERN) {
name.fullNameStyle = bestGuess;
return;
}
int guess = guessFullNameStyle(name.familyName);
if (guess != FullNameStyle.UNDEFINED) {
if (guess != FullNameStyle.CJK && guess != FullNameStyle.WESTERN) {
name.fullNameStyle = guess;
return;
}
bestGuess = guess;
}
guess = guessFullNameStyle(name.middleName);
if (guess != FullNameStyle.UNDEFINED) {
if (guess != FullNameStyle.CJK && guess != FullNameStyle.WESTERN) {
name.fullNameStyle = guess;
return;
}
bestGuess = guess;
}
guess = guessFullNameStyle(name.prefix);
if (guess != FullNameStyle.UNDEFINED) {
if (guess != FullNameStyle.CJK && guess != FullNameStyle.WESTERN) {
name.fullNameStyle = guess;
return;
}
bestGuess = guess;
}
guess = guessFullNameStyle(name.suffix);
if (guess != FullNameStyle.UNDEFINED) {
if (guess != FullNameStyle.CJK && guess != FullNameStyle.WESTERN) {
name.fullNameStyle = guess;
return;
}
bestGuess = guess;
}
name.fullNameStyle = bestGuess;
}
* Makes the best guess at the expected full name style based on the character set
* used in the supplied name.
*/
private void guessFullNameStyle(NameSplitter.Name name) {
if (name.fullNameStyle != FullNameStyle.UNDEFINED) {
return;
}
int bestGuess = guessFullNameStyle(name.givenNames);
// A mix of Hanzi and latin chars are common in China, so we have to go through all names
// if the name is not JANPANESE or KOREAN.
if (bestGuess != FullNameStyle.UNDEFINED && bestGuess != FullNameStyle.CJK
&& bestGuess != FullNameStyle.WESTERN) {
name.fullNameStyle = bestGuess;
return;
}
int guess = guessFullNameStyle(name.familyName);
if (guess != FullNameStyle.UNDEFINED) {
if (guess != FullNameStyle.CJK && guess != FullNameStyle.WESTERN) {
name.fullNameStyle = guess;
return;
}
bestGuess = guess;
}
guess = guessFullNameStyle(name.middleName);
if (guess != FullNameStyle.UNDEFINED) {
if (guess != FullNameStyle.CJK && guess != FullNameStyle.WESTERN) {
name.fullNameStyle = guess;
return;
}
bestGuess = guess;
}
guess = guessFullNameStyle(name.prefix);
if (guess != FullNameStyle.UNDEFINED) {
if (guess != FullNameStyle.CJK && guess != FullNameStyle.WESTERN) {
name.fullNameStyle = guess;
return;
}
bestGuess = guess;
}
guess = guessFullNameStyle(name.suffix);
if (guess != FullNameStyle.UNDEFINED) {
if (guess != FullNameStyle.CJK && guess != FullNameStyle.WESTERN) {
name.fullNameStyle = guess;
return;
}
bestGuess = guess;
}
name.fullNameStyle = bestGuess;
}
由于单纯的数字不满足任何条件，被置为UNDEFINED，根据下面代码被判断为使用默认西文格式：
/**
* Parses a full name and returns parsed components in the Name object
* with a given fullNameStyle.
*/
public void split(Name name, String fullName, int fullNameStyle) {
if (fullName == null) {
return;
}
name.fullNameStyle = fullNameStyle;
switch (fullNameStyle) {
case FullNameStyle.CHINESE:
splitChineseName(name, fullName);
break;
case FullNameStyle.JAPANESE:
splitJapaneseName(name, fullName);
break;
case FullNameStyle.KOREAN:
splitKoreanName(name, fullName);
break;
default:
splitWesternName(name, fullName);
}
}
* Parses a full name and returns parsed components in the Name object
* with a given fullNameStyle.
*/
public void split(Name name, String fullName, int fullNameStyle) {
if (fullName == null) {
return;
}
name.fullNameStyle = fullNameStyle;
switch (fullNameStyle) {
case FullNameStyle.CHINESE:
splitChineseName(name, fullName);
break;
case FullNameStyle.JAPANESE:
splitJapaneseName(name, fullName);
break;
case FullNameStyle.KOREAN:
splitKoreanName(name, fullName);
break;
default:
splitWesternName(name, fullName);
}
}
所以可以在split方法中添加西文的支持，并将默认置为splitChineseName，这样就可以使”1 2 3″显示为”1 2 3″(存储在数据库中的格式变化，ヽ(｀⌒´)ノ不会有人使用数字的名字)，修改如下：
switch (fullNameStyle) {
case FullNameStyle.CHINESE:
splitChineseName(name, fullName);
break;
case FullNameStyle.JAPANESE:
splitJapaneseName(name, fullName);
break;
case FullNameStyle.KOREAN:
splitKoreanName(name, fullName);
break;
// Begin: [ty, 2013-09-17] Modified for Num name @{
//default:
// splitWesternName(name, fullName);
case FullNameStyle.WESTERN:
splitWesternName(name, fullName);
break;
default:
splitChineseName(name, fullName);
// End: [ty, 2013-09-17] Modified for Num name @}
}
case FullNameStyle.CHINESE:
splitChineseName(name, fullName);
break;
case FullNameStyle.JAPANESE:
splitJapaneseName(name, fullName);
break;
case FullNameStyle.KOREAN:
splitKoreanName(name, fullName);
break;
// Begin: [ty, 2013-09-17] Modified for Num name @{
//default:
// splitWesternName(name, fullName);
case FullNameStyle.WESTERN:
splitWesternName(name, fullName);
break;
default:
splitChineseName(name, fullName);
// End: [ty, 2013-09-17] Modified for Num name @}
}
