Launch Intent on click of ExpandableListView

Launch Intent on click of ExpandableListView - android

Good evening everyone !
I am currently working on an ExpandableListView.
The parent contains 1 ImageView.
The child contains 1 TextView and 3 Buttons.
In terms of display, no problem: everything works as I want.
However, I want to add actions to my buttons and I realize that when I put a SetOnclickListener in the getChildView I am not able to launch a new INTENT.
The examples I find on the internet seem to show only clicks on dynamic elements. However, the buttons are not dynamic in my case.
I planned to use a variable to do a SWITCH and thus launch the right INTENT.
But since it doesn't work, I wonder if my direction is the right one.

Can somoene help me ?
I want to start a new intent on click on Button.
Edit : i add child Click Listener on MainActivity but its works only if i set clickable,focusable = false on the 3 Buttons in layout list_item.xml.
And than the click is on the complete child. I can't say if the click is on Button 1, 2 or 3.
Can we fix it ?

Problem solved.
I do this in ExpandableListAdapter in getChildView.
param.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent next = new Intent(parent.getContext(), parametres.class);
parent.getContext().startActivity(next);
}
});

Losing focus when notifyDataSetChanged() is called in ExpandableListView

I have an ExpandableListView which contains 2 TextViews and an EditText for entering amount for each child and it allows inline edit.
I need to to change the amount value for the group instantly when one of its child's amount changed.
I have done that but the problem is that when I called the notifyDataSetChanged() method for showing the change in group I lost the focus from the current edittext. That is, if I changed the amount field in the first child of a group and then click on the amount field of the second child, the focus is still on the first child because of the notifyDataSetChanged().
How can I solve this?
My code is below.

Try to set setOnGroupClickListener:
adapter.setInflater((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE), this);
expandableList.setAdapter(adapter);
expandableList.setOnChildClickListener(this);
expandableList.setOnGroupClickListener(this); //Implement inteface ExpandableListView.OnGroupClickListener

Only expandable listview showing up in activity

I'm making an android app for an automatic salad machine. The app lets you choose your ingredients and such, and then sends it to the machine. I set up an activity with an expandable listview to hold the ingredients, but I also need a next button on the activity and a nutritional information box below it. I added them to the activity, but when I run it only the expandable listview shows up.
Here's the code for the activity:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:weightSum="1">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next"
android:id="#+id/button"
android:layout_gravity="right" />
<ExpandableListView
android:id="#+id/list"
android:layout_height="286dp"
android:layout_width="match_parent"
android:groupIndicator="#null"
android:divider="#A4C739"
android:dividerHeight="0.5dp"
android:layout_weight="1.15" />
<TextView
android:layout_width="match_parent"
android:layout_height="77dp"
android:text="Nutrition Facts:"
android:id="#+id/nutritionTV" />
</LinearLayout>
and here's the code for the class that goes with it:
package com.picknchew.companionapp;
import java.util.ArrayList;
import android.app.ExpandableListActivity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.widget.ExpandableListView;
public class ChooseIngredientsActivity extends ExpandableListActivity{
private ArrayList<String> parentItems = new ArrayList<String>();
private ArrayList<Object> childItems = new ArrayList<Object>();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// this is not really necessary as ExpandableListActivity contains an ExpandableList
//setContentView(R.layout.main);
ExpandableListView expandableList = getExpandableListView(); // you can use (ExpandableListView) findViewById(R.id.list)
expandableList.setDividerHeight(2);
expandableList.setGroupIndicator(null);
expandableList.setClickable(true);
setGroupParents();
setChildData();
MyExpandableAdapter adapter = new MyExpandableAdapter(parentItems, childItems);
adapter.setInflater((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE), this);
expandableList.setAdapter(adapter);
expandableList.setOnChildClickListener(this);
}
public void setGroupParents() {
parentItems.add("Lettuce");
parentItems.add("Protein");
parentItems.add("Fruit");
parentItems.add("Dressings");
}
public void setChildData() {
// Android
ArrayList<String> child = new ArrayList<String>();
child.add("Romain");
child.add("Iceberg");
child.add("Arugula");
child.add("Green");
childItems.add(child);
// Core Java
child = new ArrayList<String>();
child.add("Tofu");
child.add("Shredded Cheddar");
child.add("Sliced Eggs");
child.add("Beans");
child.add("Avocado");
childItems.add(child);
// Desktop Java
child = new ArrayList<String>();
child.add("Melon");
child.add("Watermelon");
child.add("Pineapple");
child.add("Grapefruit");
childItems.add(child);
// Enterprise Java
child = new ArrayList<String>();
child.add("Honey Mustard");
child.add("Ranch");
child.add("Caesar");
child.add("Vinaigrette");
childItems.add(child);
}
}
and finally here's the code for the expandable list view adapter, in case that's relevant:
package com.picknchew.companionapp;
import java.util.ArrayList;
import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;

import android.widget.CheckBox;
import android.widget.CheckedTextView;
import android.widget.TextView;
import android.widget.Toast;
public class MyExpandableAdapter extends BaseExpandableListAdapter {
private Activity activity;
private ArrayList<Object> childtems;
private LayoutInflater inflater;
private ArrayList<String> parentItems, child;
public MyExpandableAdapter(ArrayList<String> parents, ArrayList<Object> childern) {
this.parentItems = parents;
this.childtems = childern;
}
public void setInflater(LayoutInflater inflater, Activity activity) {
this.inflater = inflater;
this.activity = activity;
}
#Override
public View getChildView(int groupPosition, final int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
child = (ArrayList<String>) childtems.get(groupPosition);
CheckBox checkbox = null;
if (convertView == null) {
convertView = inflater.inflate(R.layout.group, null);
}
checkbox = (CheckBox) convertView.findViewById(R.id.checkBox2);
checkbox.setText(child.get(childPosition));
convertView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(activity, child.get(childPosition),
Toast.LENGTH_SHORT).show();
}
});
return convertView;
}
#Override
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = inflater.inflate(R.layout.child, null);
}
((CheckedTextView) convertView).setText(parentItems.get(groupPosition));
((CheckedTextView) convertView).setChecked(isExpanded);
return convertView;
}
#Override
public Object getChild(int groupPosition, int childPosition) {
return null;
}
#Override
public long getChildId(int groupPosition, int childPosition) {
return 0;
}
#Override
public int getChildrenCount(int groupPosition) {
return ((ArrayList<String>) childtems.get(groupPosition)).size();
}
#Override
public Object getGroup(int groupPosition) {
return null;
}
#Override
public int getGroupCount() {
return parentItems.size();
}
#Override
public void onGroupCollapsed(int groupPosition) {
super.onGroupCollapsed(groupPosition);
}
#Override
public void onGroupExpanded(int groupPosition) {
super.onGroupExpanded(groupPosition);
}
#Override
public long getGroupId(int groupPosition) {
return 0;
}
#Override
public boolean hasStableIds() {
return false;
}
#Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return false;
}
}

Mixing fixed heights with weights won't work.
What you can do: set all elements' height to 0 and assign them weights.
What I would do: use a RelativeLayout, put the Button at the top, the TextView at the bottom (alignParentBottom="true") and the ListView inbetween like
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next"
android:id="#+id/button" />
<TextView
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="77dp"
android:text="Nutrition Facts:"
android:id="#+id/nutritionTV" />
<ExpandableListView
android:layout_above="#+id/nutritionTV"
android:layout_below="#+id/button"
android:id="#+id/list"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:groupIndicator="#null"
android:divider="#A4C739"
android:dividerHeight="0.5dp" />
</RelativeLayout>
Result:
EDIT: You have to actually use this layout, which you at the moment don't do:
// this is not really necessary as ExpandableListActivity contains an ExpandableList
//setContentView(R.layout.main);
Uncomment the setContentView line. Don't forget to assign the views correctly, ie
ExpandableListView expandableList = getExpandableListView(); // you can use (ExpandableListView) findViewById(R.id.list)
will become
ExpandableListView expandableList = (ExpandableListView) findViewById(R.id.list)

Android expandablelistview with 6 to 7 textviews and an imageview as child views

I have gone through many tutorials and implemented expandablelistview with one textview as a child of groupview. Now i need to implement expandablelistview with 6-7 textviews and an imageview as childs of every group.
Can anyone help..

(ExpandableListView),When I click button,update ImageView

when click button in child view then update imageview in group.
The problem is when I click the button, if all the checkbox selected,the imageview show the last one, not all checkbox selected, the imageview show the second one else show the first one!
The question is when I click the button,the image view cannot update in the correct position!
