Android Listview搜索工作不正常
请在我的代码中帮助我，它不会搜索完美，除了可搜索的字符串之外，所有其他值都保留在它们的位置上 这是filterable类的代码Android Listview搜索工作不正常,android,search,android-listview,android-filter,android-filterable,Android,Search,Android Listview,Android Filter,Android Filterable,请在我的代码中帮助我，它不会搜索完美，除了可搜索的字符串之外，所有其他值都保留在它们的位置上 这是filterable类的代码 import java.util.ArrayList; import java.util.Arrays; import java.util.List; import java.util.StringTokenizer; import android.app.Activity; import android.content.

提前感谢：）您可以为此选择另一个技巧，在输入搜索文本的编辑文本上设置一个textWatcher
searchText.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
@Override
public void afterTextChanged(Editable s) {
String text = searchText.getText().toString()
.toLowerCase(Locale.getDefault());
lviewAdapter.filter(text);
}
});
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
temp.clear();
if (charText.length() == 0) {
temp.addAll(list_original);
} else {
for (Abc abc: list_original) {
// if you want to search via policy
if (abc.getPolicy().toLowerCase(Locale.getDefault())
.contains(charText)) {
temp.add(abc);
}
}
}
notifyDataSetChanged();
}
创建两个Abc类型的ArrayList，一个是temp，另一个是original，始终将数据从temp列表传递到getview方法中的listview，这样您就可以在temp中进行更改，而不是在原始列表中进行更改。在上面的例子中，临时列表首先被清除，然后运行循环检查原始列表中的搜索文本是否匹配，然后将该对象添加到临时列表中，并调用notifyDataSetChanged。。瞧，你的数据是从哪里来的？sqlite db？检查：我正在从“WebService”获取数据，并通过一堆数组从主类发送数据将数据存储到sqlite db，它会将您的代码简化为现有代码的1/3很多东西我无法更改为sqlite brother。。。。嗯，Haresh chhelana，我不能在我的代码中完美地实现这一点。请帮我换一种方式兄弟，我是android新手，我无法做出你所说的改变。。。您能在skyp或team viewer上查看我的代码吗？请将您的代码通过电子邮件发送给我@luckysingh781@gmail.com，我会尽力让它工作的
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
temp.clear();
if (charText.length() == 0) {
temp.addAll(list_original);
} else {
for (Abc abc: list_original) {
// if you want to search via policy
if (abc.getPolicy().toLowerCase(Locale.getDefault())
.contains(charText)) {
temp.add(abc);
}
}
}
notifyDataSetChanged();
}
