i am creating an application, which i use to create a list of things that i have in SQLite database
i created a Fragment with a button that add a xml file to my LinearLayout , it works good , but i want to grab EditText and Spinner data and put them in a JSONobject but i don't know how , i don't have IDs of dynamically created views
My Fragment XML

You need to use the recyclerview to display your list items. Using recyclerview you can get view like -
View view = recyclerview.findViewHolderForAdapterPosition(pos).itemView;
Spinner spinner = view.findViewById(R.id.mySpinner);
This will return you a spinner of whichever position you have passed and afterwards get data from it.
Similarly, you can get view of edittext by using -
EditText edtTxt = view.findViewById(R.id.myEdtTxt);
To see how to get data from database and display that in recyclerview, check the example here - https://github.com/incipientinfo/db-queries

I define layout row which I inflate and add view pragmatically to a linear layout.
I wanna something like this,
https://i.stack.imgur.com/EKPmJ.png
Here is xml of my main activity where I am inflating the costume view row
<?xml version="1.0" encoding="utf-8"?>

here is my xml code of row which I am inflating:

}
}
}
}
but when I inflate row my image view get cutoff which I not want I tried with negative margin but it not work
here what it looks like
custom overlapping row
what I do so I over lap image to above view?
Try changing your layout to this.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="its text view"
/>
<Button
android:id="#+id/nameButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/name"
/>
</RelativeLayout>
<ImageView
android:layout_marginTop="25dp"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#mipmap/ic_launcher_round"/>
</RelativeLayout>
When you put in another row, that row needs to be pushed up so the android icon that is there now overlays it.

Found the answer atlast.
Don't use setOnItemClickListener for item click. Use item view click inside adapter method by using setOnClickListener(). Do things in onClick()
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
View listItemView = convertView;
if (listItemView == null)
{
listItemView = LayoutInflater.from(getContext()).inflate(R.layout.participant_list_item, parent, false);
}
listItemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
Toast.makeText(mContext, "click item",Toast.LENGTH_LONG).show();
}
});
Participant currentParticipant = getItem(position);
if(currentParticipant.getParticipantGender().equals("F"))
{
TextView idView = (TextView) listItemView.findViewById(R.id.participant_list_item_id);
idView.setTextColor(getColor(mContext, R.color.colorPrimary));
idView.setText(currentParticipant.getParticipantId());
}
else if(currentParticipant.getParticipantGender().equals("M"))
{
TextView idView = (TextView) listItemView.findViewById(R.id.participant_list_item_id);
idView.setTextColor(getColor(mContext, R.color.colorAccent));
idView.setText(currentParticipant.getParticipantId());
}
TextView nameView = (TextView) listItemView.findViewById(R.id.participant_list_item_name);
nameView.setText(currentParticipant.getParticipantName());
final EditText notesView = (EditText) listItemView.findViewById(R.id.participant_list_item_notes);
notesView.setText(currentParticipant.getParticipantNotes());
CheckBox checkedView = (CheckBox) listItemView.findViewById(R.id.participant_list_item_checkbox);
if (currentParticipant.getParticipantCheck().equals("1"))
{
checkedView.setChecked(true);
}
else
{
checkedView.setChecked(false);
}
return listItemView;
}
Remove this from participant_list_item.xml
android:descendantFocusability="blocksDescendants"
Thank you every one for the help.
<CheckBox
android:id="#+id/participant_list_item_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:focusable="false"
android:clickable="false"
android:layout_marginLeft="16dp"
android:layout_marginStart="16dp" />
Try to replace your CheckBox and add this two line
android:focusable="false"
android:clickable="false"
Try this should work in participant_list_item.xml and remove from listview
android:descendantFocusability="blocksDescendants"
you have to do it like this
private EditText notes;
private CheckBox checkBox;
and put these above onclick
notes = (EditText) rootView.findViewById(R.id.participant_list_item_notes);
String text = notes.getText().toString();
Log.v("Participant Text",text);
checkBox = (CheckBox) rootView.findViewById(R.id.participant_list_item_checkbox);
edittext and check box are the view in the listview
hope this will help you
android:clickable=true
Make sure that you have added clickable property to true.
In participantslist.xml file:
<ListView
android:id="#+id/participant_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#color/divider"
android:dividerHeight="1dp"
android:descendantFocusability="beforeDescendants"
android:drawSelectorOnTop="true"
android:headerDividersEnabled="true"
android:clickable=true/>
And let me know if this suggestion was wrong?
I created a custom listview with the base adapter, but for some reason can not click on the button inside the individual list views.
Here is the code the the main layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin" tools:context=".MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Light List"
android:id="#+id/lightName"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/loginbutton"
android:id="#+id/button"
android:onClick="buttonClicked"
android:layout_alignParentBottom="true"
android:layout_alignLeft="#+id/lightName"
android:layout_alignStart="#+id/lightName" />
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/lightList"
android:layout_below="#+id/lightName"
android:layout_above="#+id/button"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"/>
</RelativeLayout>
Here is the code for views in the list:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/lightList"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Medium Text"
android:id="#+id/lightName"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:id="#+id/statusText"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/buttonoff"
android:focusable="true"
android:enabled="true"
android:clickable="true" />
</LinearLayout>
Lastly here is the adapter code:
public ArrayList<myLight> dataSet = new ArrayList<myLight>();
public void makeLightList(ArrayList<myLight> lights) {
Iterator<myLight> iter = lights.iterator();
while(iter.hasNext()) {
dataSet.add(iter.next());
}
}
#Override
public int getCount() {
return dataSet.size();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View v;
LayoutInflater inflater = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = inflater.inflate(R.layout.lightlistlayout, null);
TextView name = (TextView) findViewById(R.id.lightName);
name.setText(dataSet.get(position).name);
TextView status = (TextView) findViewById(R.id.statusText);
if(dataSet.get(position).reachable) {
if(dataSet.get(position).isOn) {
status.setText("Light is On");
} else {
status.setText("Light is Off");
}
} else {
status.setText("Light is currently not reachable");
}
dataHolder dh = new dataHolder();
dh.name = dataSet.get(position).name;
//Handle Off button click from list view
Button offButton = (Button) findViewById(R.id.buttonoff);
offButton.setTag(dh);
offButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
dataHolder dhv = new dataHolder();
dhv = (dataHolder)v.getTag();
Toast.makeText(getBaseContext(), dhv.name + " Turned Off", Toast.LENGTH_LONG).show();
}
});
return v;
}
};
I am not sure if my onclicklistener is correct as I can't click on the button at all yet. Here is a picture showing the button. I have messed with different focus and clickable settings in the xml file and no luck. I added a seeker bar that I was able to slide that back and forth, but the button will not let me click it.
v = inflater.inflate(R.layout.lightlistlayout, null);
Here you have inflated the row file for your adapter and the below are your id initialization and for that you have not added your view to your id, so try this.
TextView name = (TextView) v.findViewById(R.id.lightName);
TextView status = (TextView) v.findViewById(R.id.statusText);
Button offButton = (Button) v.findViewById(R.id.buttonoff);
try changing
android:focusable="true" to android:focusable="false" in Button's xml
I have a class that extends a Fragment. I want when press a button from An Activity to opens this Fragment with its layout in dialog in addition to that the fragment opens normally in its place. Is this possible?
This is my Fragment (TipsFragment.java)

Since Android supports nesting Fragments (available in the support library) you could show your TipsFragment as a content of another DialogFragment. Avoid this solution whenever possible.
A better solution would be to make TipsFragment extend DialogFragment and that way you can either show the Fragment inline or in a dialog.
1 - Make TipsFragment extends DialogFragment
public class TipsFragment extends DialogFragment {...}
2 - On button click use FragmentTransaction.add or FragmentTransaction.replace to show the DialogFragment inline or include it in your layout and change its visibility.
3 - Show the TipsFragment as a dialog
TipsFragment fr = new TipsFragment();
fr.show(getSupportFragmentManager(), "dialog_fragment_tag");

I'm trying to create a DialogFragment with a ListView and some Buttons. I'm declaring all of them i the layout file and the buttons are working fine but the ListView is null when i use fineViewByID().
Here's my xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/category_picker"
android:layout_gravity="center"
android:orientation="vertical" >
<ListView
android:id="#+id/lvCategorys"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_weight="0.5" >
</ListView>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_gravity="bottom"
android:layout_weight="0.5"
android:orientation="horizontal" >
<Button
android:id="#+id/btnAddNew"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:text="#string/cpf_btnAddNew" />
<Button
android:id="#+id/btnConfig"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:text="#string/cpf_btnConfig" />
</LinearLayout>
</LinearLayout>
And here is the FragmentDialog:
package com.example.spendo.fragments;
imports....
public class CategoryPickerFragment extends DialogFragment implements OnItemClickListener{
private CategoryGroup categoryGroup;
private ListView lvCategorys;
private ArrayAdapter<String> lvAdapter;
private Button btnAddNew, btnConfig;
public CategoryPickerFragment() {
// Empty constructor required for DialogFragment
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_category_picker, container);
getDialog().setTitle("Hello");
categoryGroup = General.getActiveCategoryGroup(this.getActivity());
System.out.println(categoryGroup);
btnAddNew = (Button) this.getActivity().findViewById(R.id.btnAddNew);
btnConfig = (Button) this.getActivity().findViewById(R.id.btnConfig);
lvCategorys = (ListView) this.getActivity().findViewById(R.id.lvCategorys);
if(lvCategorys == null){ //this returns "lvCategorys is null"
System.out.println("lvCategorys is null");
}else{
System.out.println(lvCategorys + " is not null");
}
lvAdapter = new ArrayAdapter<String>(this.getActivity(),android.R.layout.simple_list_item_1, categoryGroup.getNameArray());
System.out.println(lvAdapter);
ArrayList<String> nameArray = categoryGroup.getNameArray();
lvAdapter.clear();
for(int i = 0; i < nameArray.size(); i++){
lvAdapter.add((String) nameArray.get(i));
}
lvAdapter.notifyDataSetChanged();
lvCategorys.setAdapter(lvAdapter);
return view;
}
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
}
}
Does anyone see my problem. (I'm quite new to android, altho i've done some java in the past).
//Sverker
I think you need to replace
btnAddNew = (Button) this.getActivity().findViewById(R.id.btnAddNew);
btnConfig = (Button) this.getActivity().findViewById(R.id.btnConfig);
lvCategorys = (ListView) this.getActivity().findViewById(R.id.lvCategorys);
with
btnAddNew = (Button) view.findViewById(R.id.btnAddNew);
btnConfig = (Button) view.findViewById(R.id.btnConfig);
lvCategorys = (ListView) view.findViewById(R.id.lvCategorys);
