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:

listView.addHeaderView(header);

This is the layout I am trying to use for header
<?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="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingLeft="25dp"
android:paddingRight="10dp"
android:orientation="horizontal">
<TextView android:id="#+id/adapter_header_textview_column1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="4"
android:textColor="#color/defaultTextColor"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="28sp"
android:text="Assesment ID" />
<TextView android:id="#+id/adapter_header_textview_column2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="4"
android:textColor="#color/defaultTextColor"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="28sp"
android:text="Name" />
<TextView android:id="#+id/adapter_header_textview_column3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="3"
android:textColor="#color/defaultTextColor"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="28sp"
android:text="Date"/>
<CheckBox
android:id="#+id/header_check_box"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:color="#color/defaultTextColor"
android:layout_weight=".5"
android:gravity="center" />
</LinearLayout>
<View
android:layout_width="fill_parent"
android:layout_height="5dp"
android:background="#color/BPGreenColor" />
<ListView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>
Then this is the array adapter I am using:
public class FastAssesmentListAdapter extends ArrayAdapter<Data> {
private static int LAYOUT_ID = R.layout.list_adapter_with_checkbox_three_column;
private final Data[] assesments;
private final Context context;
LinearLayout listHeader;
static class ViewHolder {
protected TextView column1;
protected TextView column2;
protected TextView column3;
protected CheckBox checkbox;
}
public FastAssesmentListAdapter(Context context, Data[] assesments) {
super(context, LAYOUT_ID, assesments);
this.context = context;
this.assesments = assesments;
}
//ListFragment and array adapter will automatically call this over and over to auto populate the list
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final Data item = getItem(position);
// Formulate row view (create if it does not exist yet)
View view = convertView;
if(view == null) {
LayoutInflater inflater = ((Activity) getContext()).getLayoutInflater();
view = inflater.inflate(LAYOUT_ID, null);
final ViewHolder viewHolder = new ViewHolder();
viewHolder.column1 = (TextView) view.findViewById(R.id.adapter_textview_column1);
viewHolder.column2 = (TextView) view.findViewById(R.id.adapter_textview_column2);
viewHolder.column3 = (TextView) view.findViewById(R.id.adapter_textview_column3);
viewHolder.checkbox = (CheckBox) view.findViewById(R.id.check_box);
view.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "Clicked",
Toast.LENGTH_SHORT).show();
Intent intent = new Intent(getContext(), FacilityActivity.class);
getContext().startActivity(intent);
}
});
if(viewHolder.checkbox != null) {
viewHolder.checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
if(isChecked) {
item.setSelected(isChecked);
Toast.makeText(getContext(), "Checked",
Toast.LENGTH_SHORT).show();
}
}
});
}
view.setTag(viewHolder);
viewHolder.checkbox.setTag(position);
}
ViewHolder viewHolder = (ViewHolder) view.getTag();
viewHolder.checkbox.setTag(position);
viewHolder.column1.setText(item.getColumn1());
viewHolder.column2.setText(item.getColumn2());
viewHolder.column3.setText(item.getColumn3());
viewHolder.checkbox.setChecked(item.isSelected());
return view;
}
}
on a side note, the onlistitemclicked in the fragment doesnt work, i have to set a listener in the adapter and then it works. any ideas on that? but mainly I need to figure out how to use a custom header and custom rows in the list view. Here is the layout for the rows
<?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="wrap_content"
android:paddingLeft="25dp"
android:paddingRight="10dp"
android:orientation="horizontal">
<TextView android:id="#+id/adapter_textview_column1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="4"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="25sp" />
<TextView android:id="#+id/adapter_textview_column2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="4"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="25sp" />
<TextView android:id="#+id/adapter_textview_column3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="3"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="25sp" />
<CheckBox
android:id="#+id/check_box"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight=".5"
android:gravity="center" />
</LinearLayout>
