我是Android新手。我在listview组件中填充数据，之后也进行一些编辑，然后从适配器edittext数据中获取。我得到的是它以前的数据不是当前编辑的数据。
我的Java代码是，
save.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Handler handler = new Handler();
final Runnable r = new Runnable() {
public void run() {
Cursor c = db.getData();
List<ClientDetail> arrayList = new ArrayList<ClientDetail>();
while (c.moveToNext()) {
ClientDetail cd = new ClientDetail();
cd.setContactID(c.getString(1));
cd.setContactname(c.getString(2));
cd.setRefCompanyId_EntityMaster(c.getString(3));
arrayList.add(cd);
}
List<Worklog> wl = RSMIT.getInstance().getWorklogList();
List<Worklog> wolo = new ArrayList<Worklog>();
View v;
EditText et;
Worklog worklog = null;
for (int i = 0; i < listView.getCount(); i++) {
v = listView.getAdapter().getView(i, null, listView);
et = (EditText) v.findViewById(R.id.txtwldes);
chkwl = (CheckBox) v.findViewById(R.id.chkwl);
spinner = (NiceSpinner) v.findViewById(R.id.spinner);
spinner1 = (NiceSpinner) v.findViewById(R.id.spinner1);
worklog = new Worklog();
if (wl.get(i).getIsTaskEnable() == null) {
worklog.setIsTaskEnable(null);
} else {
worklog.setIsTaskEnable(wl.get(i).getIsTaskEnable());
}
if (wl.get(i).getTaskStatusId() == null) {
worklog.setTaskStatusId(null);
} else {
worklog.setTaskStatusId(wl.get(i).getTaskStatusId());
}
worklog.setIsWorkLogEnable(wl.get(i).getIsWorkLogEnable());
worklog.setColor(wl.get(i).getColor());
worklog.setIsCheckTickTicked(wl.get(i).getIsCheckTickTicked());
worklog.setTaskType(wl.get(i).getTaskType());
if (et.isEnabled() == true) {
worklog.setWorklogDescription(et.getText().toString().trim());
} else {
worklog.setWorklogDescription("");
}
Log.e("edt txt", et.getText().toString());
if (chkwl.isChecked()) {
worklog.setIsCopy("true");
} else {
worklog.setIsCopy("false");
}
for (int j = 0; j < arrayList.size(); j++) {
if (spinner1.getItem(0).equalsIgnoreCase("Select")) {
worklog.setClientID(null);
} else {
worklog.setClientID(spinner1.getItem(0));
}
}
if (wl.get(i).getTimeTrack().equalsIgnoreCase("09:00-09:30")) {
worklog.setTimeTrack("chkbox0900");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("09:30-10:00")) {
worklog.setTimeTrack("chkbox0930");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("10:00-10:30")) {
worklog.setTimeTrack("chkbox1000");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("10:30-11:00")) {
worklog.setTimeTrack("chkbox1030");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("11:00-11:30")) {
worklog.setTimeTrack("chkbox1100");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("11:30-12:00")) {
worklog.setTimeTrack("chkbox1130");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("12:00-12:30")) {
worklog.setTimeTrack("chkbox1200");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("12:30-13:00")) {
worklog.setTimeTrack("chkbox1230");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("13:00-13:30")) {
worklog.setTimeTrack("chkbox0100");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("13:30-14:00")) {
worklog.setTimeTrack("chkbox0130");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("14:00-14:30")) {
worklog.setTimeTrack("chkbox0200");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("14:30-15:00")) {
worklog.setTimeTrack("chkbox0230");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("15:00-15:30")) {
worklog.setTimeTrack("chkbox0300");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("15:30-16:00")) {
worklog.setTimeTrack("chkbox0330");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("16:00-16:30")) {
worklog.setTimeTrack("chkbox0400");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("16:30-17:00")) {
worklog.setTimeTrack("chkbox0430");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("17:00-17:30")) {
worklog.setTimeTrack("chkbox0500");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("17:30-18:00")) {
worklog.setTimeTrack("chkbox0530");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("18:00-18:30")) {
worklog.setTimeTrack("chkbox0600");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("18:30-19:00")) {
worklog.setTimeTrack("chkbox0630");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("19:00-19:30")) {
worklog.setTimeTrack("chkbox0700");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("19:30-20:00")) {
worklog.setTimeTrack("chkbox0730");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("20:00-20:30")) {
worklog.setTimeTrack("chkbox0800");
} else if (wl.get(i).getTimeTrack().equalsIgnoreCase("20:30-21:00")) {
worklog.setTimeTrack("chkbox0830");
}
wolo.add(worklog);
}
Gson gson = new Gson();
JsonElement element = gson.toJsonTree(wolo,
new TypeToken<List<Worklog>>() {
}.getType());
Log.e("Element Value", element.getAsJsonArray().toString());
}
};
handler.postDelayed(r, 1000);
}
});
所以，我的问题是如何从listview edittext中获取编辑后的值？谢谢。

您应该使用TextWatcher并在文本更改后使用方法更改文本之前请检查此链接http://developer.android.com/reference/android/text/TextWatcher.html
这是示例代码，仅为您提供指导。但请先阅读文档。
//suppose this is your edit text
EditText et;
//addTextChange listener
et.addTextChangedListener(editTextTextWatcher);
private TextWatcher editTextTextWatcher = 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) {
//Write your code to handel text changes here
}
};

试试这个：
EG：
ObjectEntity.class：
public class ObjectEntity {
String name;
EditText editText;
public ObjectEntity() {
}
public ObjectEntity(String name, EditText editText) {
this.name = name;
this.editText = editText;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public EditText getEditText() {
return editText;
}
public void setEditText(EditText editText) {
this.editText = editText;
}}
在适配器中：
ArrayList<ObjectEntity>arrayList= new ArrayList<ObjectEntity>();
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
LayoutInflater inflater = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = inflater.inflate(R.layout.item_listview, parent,
false);
}
EditText mEdt=(EditText )convertView.findViewById(R.id.mEdext);
arrayList.get(position).setEditText(mEdt);
return convertView;
}
在代码活动中：
save.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
for (int i = 0; i < arrayList.size(); i++) {
EditText editText = arrayList.get(i).getEditText();
String edtContent = editText.getText().toString();
//check vule here
}
}
});
