Android列表视图搜索无法正常运行
请在我的代码中帮助我，它不会搜索完美所有其他值保留在他们的位置，除了搜索字符串。
以下是可过滤类的代码

编辑文本事件处理程序
searchText.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub
ClaimList.this.lviewAdapter.getFilter().filter(s.toString());
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
}
});
搜索前
警察搜索时没有（代码中的政策＃）
提前感谢：）

您可以选择其他技巧，在编辑文本上设置textWatcher，输入搜索文本。
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);
}
});
在Adapter类中放置一个过滤器方法
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arraylists，一个是temp，一个是原始的，总是将数据从临时列表中的getview方法传递给listview，这样你就可以对temp进行更改，而不是原来的。在上面的例子中，临时列表首先清除并运行循环以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，并调用notifyDataSetChanged .. Voila
