Ich entwickle Expandablelistview in Android.

In der GroupView gibt es nur einen Titel und jede Gruppe hat eine andere ChildView.

Dieser Code funktioniert einwandfrei und ich kann in jedem Gruppenelement verschiedene ChildView-Elemente anzeigen.

In ChildView habe ich einen EditText und wenn ich auf "Fertig" klicke, möchte ich alle EditText- und Spinner-Werte erhalten, die vom Benutzer eingegeben werden.

Wenn ich zu diesem Zeitpunkt auf die Schaltfläche "Fertig" klicke, möchte ich Details erhalten, die der Benutzer in den Gruppenelementen eingibtCustomer Location usw.

Zum Beispiel: das betreffende Bild. Ich möchte die Eingabedetails erhalten, die vom Benutzer eingegeben werdenvehicle undTEST Gruppenelement.

Bitte, ich brauche Hilfe, ich möchte Werte erhalten, die vom Benutzer in den EditText jedes Gruppenelementkindes eingetragen werden.

Hier ist mein 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;
    }
