只有当我点击搜索按钮时，才能通过WEB将Filter应用于ListView。但我希望在没有单击“搜索”按钮的情况下填充EditText时过滤数据。我使用两个editText：startdate和endDate。当我点击搜索按钮时，过滤器正在工作，但我希望过滤数据，而不管在editText中输入日期的顺序。

试试这个只需添加你的edittext的addTextChangedListener就可以帮到你..
editTextEndDate.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable s) {
if(editTextStartDate.getText.toString() != ""){
getAttendanceDataWithFilter();
}
}
});

一：使用像OnFocusChangeListener这样的监听器，当Edittext失去焦点时，你可以刷新日期！ 二：在Edittext上添加TextWatcher，当文本改变时，检查并更新日期！
