I'm developing Expandablelistview in Android.
In the GroupView has only a title and every group has different ChildView.
This code is working fine and i'm able to see different ChildView's in every Group item.
In ChildView i have an EditText and when i click on done button i want to get all EditText and Spinner values which are inputs by user.
When i click on done button at that time, i want to get details which is filled by user in Group items Customer
Location
etc.
For a example : the image shown in question. I want to get the input details which is filled by user in vehicle
and TEST
group item.
Please, I need help, i want to get values which is filled by user in every group item child's EditText.
Here is my code :
MainActivity.java
public class MainActivity extends Activity {
Context mContext;
private ExpandableListView mExpandableListView;
CustomAdapter mCustomAdapter;
ArrayList<String> newCalibration = new ArrayList<String>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mContext = MainActivity.this;
newCalibration.add("CUSTOMER");
newCalibration.add("LOCATION");
newCalibration.add("VEHICLE");
newCalibration.add("TEST");
newCalibration.add("ABC");
/* genarate data for list view */
// genarateData();
/* instantiate adapter with our item list */
mCustomAdapter = new CustomAdapter(mContext, newCalibration);
/* we get list view */
mExpandableListView = (ExpandableListView) findViewById(R.id.explist_tools);
/* set adapter to list view */
mExpandableListView.setAdapter(mCustomAdapter);
mExpandableListView
.setOnGroupExpandListener(new OnGroupExpandListener() {
int previousGroup = -1;
@Override
public void onGroupExpand(int groupPosition) {
// TODO Auto-generated method stub
if (groupPosition != previousGroup) {
mExpandableListView.collapseGroup(previousGroup);
previousGroup = groupPosition;
}
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
CustomAdapter.java
public class CustomAdapter extends BaseExpandableListAdapter {

/* list of parent */

Thanks!
You aren't going to be able to go through the list and get the values from the views directly, which is probably what you were planning on doing.
Instead, just keep track of the values as the user enters them. You can keep a hash map of field name -> value in your adapter or activity. Every time the user changes a value in a field, update that field with the new value in the hashmap. When they press done, you can iterate over the map to get a list of all the fields the user changed and the values they changed them to.
To get the values of the fields as the user changes them, use a TextWatcher:
myEditText.addTextChangedListener(new TextWatcher() {
...
@Override
onTextChanged(CharSequence newText, int start, int before, int count) {
myMapOfFieldsToValues.set(myFieldName, newText);
}
}
You can add that to getChildView in your adapter. You can derive myFieldName from the position of the parent and child.
