最近开发中有个需求类似qq搜索功能,根据数字,首字母,全拼,简拼实现数据检索。之前只是根据对象的属性来对比,后来发现有局限性,所以参考一篇博客自己动手修改了一下,实现的结果还比较不错的,在这里分享一下:
参考原文:点击打开链接
效果图1 简拼:
效果2 全拼:
效果3 根据数字搜索:
下面介绍关键的类:
一、中文字符转换为拼音的实现类

三、调用

- */
- TextWatcher textWatcher = new TextWatcher() {
- @Override
- public void onTextChanged(CharSequence s, int arg1, int arg2, int arg3) {
- // TODO Auto-generated method stub
- if (s != null && s.length() > 0) {
- <span style="color:#ff00;"> </span>List<Group> listG = LocalGroupSearch.searchGroup(s, al);
- Logger.e(this, "local_group=" + listG.toString());
- TitledListView.FLAG_VIEW = true;
- FLAG_SHOW_TITLE = true;
- if (listG != null && listG.size() > 0) {
- } else {
- ToastUtil.show("搜索为空");
- }
- dAdapter.updateList(listG);
- searchUtils.showListView(dAdapter, null);
- Logger.e(this, "new_group=" + listG.toString());
- } else {
- FLAG_SHOW_TITLE = false;
- TitledListView.FLAG_VIEW = false;
- searchUtils.hideListView();
- dAdapter.updateList(al);
- }
- }
- @Override
- public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
- int arg3) {
- }
- @Override

- };
/**

*/
TextWatcher textWatcher = new TextWatcher() {
@Override

} else {

}
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
}
@Override

}
};
搞定,代码量也不是很多,自己做个总结留个笔记,也希望可以帮助到朋友们。
最近开发中有个需求类似qq搜索功能,根据数字,首字母,全拼,简拼实现数据检索。之前只是根据对象的属性来对比,后来发现有局限性,所以参考一篇博客自己动手修改了一下,实现的结果还比较不错的,在这里分享一下:

效果图1 简拼:
效果2 全拼:
效果3 根据数字搜索:

.compile(search, Pattern.CASE_INSENSITIVE);
Matcher matcher2 = pattern2.matcher(finder.getSpelling());
flag = matcher2.find();
}
return flag;
}
private static String getGroupName(Group group) {
String strName = null;
if (!TextUtils.isEmpty(group.getNaturalName())) {
strName = group.getNaturalName();
} else if (!TextUtils.isEmpty(group.getRoomName())) {
strName = group.getRoomName();
} else {
strName = "";
}
return strName;
}
}
三、调用
- /**
- * 搜索框监听
- */
- TextWatcher textWatcher = new TextWatcher() {
- @Override
- public void onTextChanged(CharSequence s, int arg1, int arg2, int arg3) {
- // TODO Auto-generated method stub
- if (s != null && s.length() > 0) {
- <span style="color:#ff00;"> </span>List<Group> listG = LocalGroupSearch.searchGroup(s, al);
- Logger.e(this, "local_group=" + listG.toString());
- TitledListView.FLAG_VIEW = true;
- FLAG_SHOW_TITLE = true;
- if (listG != null && listG.size() > 0) {
- } else {
- ToastUtil.show("搜索为空");
- }
- dAdapter.updateList(listG);
- searchUtils.showListView(dAdapter, null);
- Logger.e(this, "new_group=" + listG.toString());
- } else {
- FLAG_SHOW_TITLE = false;
- TitledListView.FLAG_VIEW = false;
- searchUtils.hideListView();
- dAdapter.updateList(al);
- }
- }
- @Override
- public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
- int arg3) {
- }
- @Override
- public void afterTextChanged(Editable arg0) {
- }
- };
/**
* 搜索框监听
*/
TextWatcher textWatcher = new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int arg1, int arg2, int arg3) {
// TODO Auto-generated method stub
if (s != null && s.length() > 0) {
<span style="color:#ff00;"> </span>List<Group> listG = LocalGroupSearch.searchGroup(s, al);
Logger.e(this, "local_group=" + listG.toString());
TitledListView.FLAG_VIEW = true;
FLAG_SHOW_TITLE = true;
if (listG != null && listG.size() > 0) {
} else {
ToastUtil.show("搜索为空");
}
dAdapter.updateList(listG);
searchUtils.showListView(dAdapter, null);
Logger.e(this, "new_group=" + listG.toString());
} else {
FLAG_SHOW_TITLE = false;
TitledListView.FLAG_VIEW = false;
searchUtils.hideListView();
dAdapter.updateList(al);
}
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
}
@Override
public void afterTextChanged(Editable arg0) {
}
};
搞定,代码量也不是很多,自己做个总结留个笔记,也希望可以帮助到朋友们。
