Develop Reference

how may i resolve ListView Problem ? ERROR: on a null object reference

hello guys i'm back again on a question conserning my final project.
i have made a googlemap app with navigation drawer using activity( no fragment). i think you know about that. then rather than using header and menu, i have use a layout where the header should be so that i can make there a listview to display events all of this is clear.

this layout (drawer_trace) will be displayed in mapActivity as a navigation Drawer. we are ok for that.
and then i have my Events Model:
public class Event
{
public int id, user_id, device_id, position_id, alert_id;
// geofence_id
public String message;
public String address;
public float altitude;
// course
public float latitude, longitude;
// power
public float speed;
public String time;
// deleted
public String device_name, geofence_name;
public boolean fitForFilter(String filterString) {
if(message.toLowerCase().contains(filterString.toLowerCase()))
return true;
if(address.toLowerCase().contains(filterString.toLowerCase()))
return true;
if(time.toLowerCase().contains(filterString.toLowerCase()))
return true;
if(device_name.toLowerCase().contains(filterString.toLowerCase()))
return true;
if(geofence_name.toLowerCase().contains(filterString.toLowerCase()))
return true;
return false;
}
i am using REST API in backend and retrofit.
everything is ok untill i try to eun the app.
it says ERROR MESSAGE:

Activity is overlapping fragment home

I'm developing a Calorie app where the user can delete an item from the listview.
PROBLEM: When the user clicks on the item it goes to the calorie details activity,when they click delete it goes back to the home fragment. As soon as I click on add another entry it crashes. Also when it goes back to fragment home it doesnt look the same the calorie details activity is over lapping the fragment home not completely replacing it.
calorieDetails.java
public class CalorieDetails extends AppCompatActivity {

So far so good... now I need to pass all this to my adapter:
public class ListAdapter extends BaseAdapter {
// Declare Variables
Context context;
LayoutInflater inflater;
private ArrayList<HashMap<String, String>> data;
private HashMap<String, String> resultp;
public ListAdapter(Context context,
ArrayList<HashMap<String, String>> d) {
this.context = context;
data = d;
}
#Override
public int getCount() {
return data.size();
}
#Override
public Object getItem(int position) {
return data.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
// Declare Variables
TextView author;
TextView comment;
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View itemView = inflater.inflate(R.layout.comment_item, parent, false);
resultp = new HashMap<String, String>();
final int pos = position;
resultp = data.get(position);
Log.e("data", data.get(position).toString());
author = (TextView) itemView.findViewById(R.id.tvauthorcomment);
author.setText(resultp.get(ContenidoNews.AUTHOR));
author.setTypeface(textofat);
comment = (TextView) itemView.findViewById(R.id.tvofcomment);
comment.setText(resultp.get(ContenidoNews.COMMENT));
comment.setTypeface(texto);
return itemView;
}
}
The result of Log.e("data full", data.toString()); its:
10-08 22:33:40.564: E/data full(26463): [{comtext=Prueba, comauthor=Mariano xxxx}, {comtext=una clarísima definición, comauthor=Susana A xxxx}]
Which, by the way, prints 7 times in the log... but it has the 2 values as I need.
Now... this it's what Log.e("data", data.get(position).toString()); gives me:
10-08 22:21:11.444: E/data(24618): {comtext=Prueba, comauthor=Mariano xxxx}
And:
author.setText(resultp.get(ContenidoNews.AUTHOR));
comment.setText(resultp.get(ContenidoNews.COMMENT));
In the adapter also only gave me the first value in my listview (comment_item.xml):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView

android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:paddingLeft="20dp"
android:text="Autor Comentario"
android:textColor="#707070"
android:textSize="20sp" />
<TextView
android:id="#+id/tvofcomment"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"

android:layout_height="1dp"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:background="#BBBBBB" />
</LinearLayout>
</LinearLayout>
I can only get the first value... I can't fix this. I'm stock since a lot of hours and nothing. I don't understand what it's the problem. Please, help!
I would thanks any answer in advance!

We shouldn’t use ListView inside the ScrollView because the list view is already ScrollView, the items in list view are already scrollable..
If you use then the list view will show only one item from the adapter.
Check this post ListView inside scrollview for more details...

Android add row to table on button click

I have a TableLayout in my application. I have Two definite Rows so far. One Row has static items assigned to it, and the other has 3 spinners assigned top it.
What I'd like to do is, add a new TableRow when ever I click on a button. So far I have the following code:
<TableRow
android:layout_width="fill_parent">
android:stretchColumns="0,1,2"
<Spinner
android:padding="3dip"
android:gravity="left"
android:id="#+id/Spinner1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="30dp" />
<Spinner
android:padding="3dip"
android:gravity="left"
android:id="#+id/Spinner2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="30dp" />
<Spinner
android:padding="3dip"
android:gravity="left"
android:id="#+id/spinner3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="30dp" />
</TableRow>
This is just me second row, the row that I want to add when ever I click said button. MY question is, how do I add the following row into my view, every time the user clicks the button? The values of the spinners will differ, but the variables will stay the same.
Edit:
More code:
/* Find Tablelayout defined in teh XML file */
TableLayout tl = (TableLayout) findViewById(R.id.listTable);
/* Create a new row to be added. */
TableRow tr = new TableRow(this);
tr.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
/* Create a Button to be the row-content. */
Button b = new Button(this);
b.setText("Add row");
b.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
/* Add Button to row. */
tr.addView(b);
/* Add row to TableLayout. */
tl.addView(tr, new TableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT, TableLayout.LayoutParams.WRAP_CONTENT));
}
View changed to this:
<TableRow
android:id="#+id/copyRow"
android:layout_width="fill_parent" >
android:stretchColumns="0,1,2"
<Spinner
android:padding="3dip"
android:gravity="left"
android:id="#+id/Spinner1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="30dp" />
<Spinner
android:padding="3dip"
android:gravity="left"
android:id="#+id/Spinner2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="30dp" />
<Spinner
android:padding="3dip"
android:gravity="left"
android:id="#+id/spinner3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="30dp" />
</TableRow>
If It makes a difference, I'm using JellyBean 4.3 as the target API

here is solution with ListView
you can finde all source code here
Activity Class

private ListView list;

// get view elements

addButton = (Button)findViewById(R.id.addButton);
//lets add few items to our list, note that selection item should not exceed length of spinners item
rows.add(new RowItem(0, 0, 0));
rows.add(new RowItem(0, 1, 2));
rows.add(new RowItem(2, 1, 1));
//create adapter and assign it to your list view
listAdapter = new SimpleListAdapter(this, R.layout.list_item, rows);
list.setAdapter(listAdapter);
