我無法從動態列表視圖中獲取edittext值。當我滾動列表視圖，進入了編輯的文本值會無形 下面是我的動態文件 -如何從列表視圖中獲取編輯文本值
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.content_servic_homepage);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
url = getResources().getString(R.string.webservice);
aq = new AQuery(ServicHomepage.this);
cd = new ConnectionDetector(ServicHomepage.this);
findviewbyId();
progressdialog();
if (cd.isConnectingToInternet()) {
getintentData();
} else {
Toast.makeText(ServicHomepage.this, "CheckIternet connection", Toast.LENGTH_SHORT).show();
}
}
private void progressdialog() {
pd = new ProgressDialog(ServicHomepage.this);
pd.setMessage("Loading...");
}
public void findviewbyId() {
recyclerview = (ListView) findViewById(R.id.service_recycler_view);
update_descrptn = (TextView) findViewById(R.id.update_descrptn);
uploadimages = (TextView) findViewById(R.id.uploadimages);
}
public void getintentData() {
SharedPreferences prefs = getSharedPreferences(Constants.PREFS_NAME, 0);
catid = prefs.getString(Constants.CATID, "");
subcatid = prefs.getString(Constants.SUBCATID, "");
user_id = prefs.getString(Constants.USERID, "");
isappointment = prefs.getString(Constants.IS_APPOINTMENT, "");
clicklistener();
}
public void clicklistener() {
uploadimages.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(getApplicationContext(), GalleryAlbumActivity.class);
startActivity(i);
}
});
update_descrptn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(ServicHomepage.this, "" + serv_adapter.getItem(POSITION), Toast.LENGTH_SHORT).show();
for (int i = 0; i < serv_adapter.getCount(); i++) {
View view = serv_adapter.getView(i,null,null);
EditText edittext = (EditText)view.findViewById(R.id.et_amount);
EditText et_description = (EditText)view.findViewById(R.id.et_description);
String str = edittext.getText().toString();
String str1 = et_description.getText().toString();
Toast.makeText(ServicHomepage.this, str + "==" + str1, Toast.LENGTH_SHORT).show();
}
updateList();
}
});
}
private void updateList() {
String substring = null, msgString = "";
String MAIN_CART = null;
MAIN_CART = "{\"service\":[%s]}";
String temstring = "";
for (int i = 0; i < arrayList.size(); i++) {
substring = "{\"title\":\"" + arrayList.get(i).getTitle() + "\",\"subcatid\":\"" + arrayList.get(i).getSubcatid()
+ "\",\"amount\":\"" + "" + "\",\"description\":\"" + "" + "\"}" + ",";
temstring = temstring + substring;
}
temstring = temstring.substring(0, temstring.length() - 1);
msgString = msgString + String.format(MAIN_CART, temstring);
Log.e("msgString=============", msgString);
}
這是所有的項目列表中的
public String parseanimcat(String object) {
try {
JSONObject json = new JSONObject(object);
JSONObject jsonobj = json.getJSONObject("data");
status1 = jsonobj.getString("status");
message = jsonobj.getString("message");
arrayList = new ArrayList<>();
JSONArray jarray = jsonobj.getJSONArray("dataFound");
for (int i = 0; i <= jarray.length(); i++) {
JSONObject jobj = jarray.getJSONObject(i);
String category = jobj.getString("category");
String subsubcat_id = jobj.getString("subsubcat_id");
Toast.makeText(ServicHomepage.this, category + "==" + subsubcat_id, Toast.LENGTH_SHORT).show();
model = new Data_Model();
model.setTitle(category);
model.setSubcatid(subsubcat_id);
arrayList.add(model);
}
} catch (JSONException e) {
e.printStackTrace();
}
return object;
}
這是添加方法我的適配器類 -
private class service_list_adapter extends ArrayAdapter<Data_Model>{
private ArrayList<Data_Model> array_list;
Context context;
String[] etValArr;
ViewHolder holder;
String[] totalValue;
Data_Model model;
HashMap<String, String> hm = new HashMap<>();
ArrayList<HashMap<String, String>> list = new ArrayList<>();
public service_list_adapter(Context context,int resourceId,ArrayList<Data_Model> arrayList) {
super(context,resourceId,arrayList);
this.context = context;
this.array_list = arrayList;
etValArr = new String[array_list.size()];
totalValue = new String[array_list.size()];
}
private class ViewHolder {
public TextView serv_title;
public EditText serv_descrptn, serv_amount;
}
public View getView(int position, View convertView, ViewGroup parent) {
model = array_list.get(position);
POSITION = position;
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = mInflater.inflate(R.layout.serv_cat_rowitem, null);
holder = new ViewHolder();
holder.serv_title = (TextView) convertView.findViewById(R.id.serv_txt);
holder.serv_descrptn = (EditText) convertView.findViewById(R.id.et_description);
holder.serv_amount = (EditText) convertView.findViewById(R.id.et_amount);
convertView.setTag(holder);
holder.serv_title.setTag(position);
holder.serv_descrptn.setTag(position);
holder.serv_amount.setTag(position);
} else
holder = (ViewHolder) convertView.getTag();
holder.serv_title.setText(model.getTitle());
holder.serv_descrptn.setText(model.getServdescription());
holder.serv_amount.setText(model.getServamount());
holder.serv_amount.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) {
model.setServamount(s.toString());
}
});
holder.serv_descrptn.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) {
model.setServdescription(s.toString());
}
});
return convertView;
}
}
