How to split this activity into 2 ListViews

How to split this activity into 2 ListViews - java

I have this listview with drinks (bebidas) but i wanted to add a new listview in the same activity for hamburguers.
My code is not working because it keeps repeating the same names.
public class Cardapios extends AppCompatActivity {
DbController db;
ListView listview_cardapios, listview_hamburguers;
public int id;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cardapios);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
db = new DbController(getBaseContext());
Bundle b = getIntent().getExtras();
if (b != null) {
id = b.getInt("id");
}
preencheLista();
// preencheLista2();
}
private void preencheLista() {
ArrayList<CardapioGetter> itens = new ArrayList<CardapioGetter>();
Cursor c = db.getBebidas(id);
while (! c.isAfterLast()) {
itens.add(new CardapioGetter(c.getString(c.getColumnIndex(DbHelper.NOME_BEBIDAS)),c.getString(c.getColumnIndex(DbHelper.VALOR_BEBIDAS))));
c.moveToNext();
}
defineAdapter(itens);
}
private void defineAdapter(ArrayList<CardapioGetter> itens) {
listview_cardapios = (ListView) findViewById(R.id.listview_cardapios);
AdapterListCardapios adapter = new AdapterListCardapios(getApplicationContext(), itens);
listview_cardapios.setAdapter(adapter);
listview_cardapios.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
CardapioGetter itemValue = (CardapioGetter) listview_cardapios.getItemAtPosition(position);
}
});
}
private void preencheLista2() {
ArrayList<CardapioGetter> itens = new ArrayList<CardapioGetter>();
Cursor h = db.getHamburguers(id);
while (! h.isAfterLast()) {
itens.add(new CardapioGetter(h.getString(h.getColumnIndex(DbHelper.NOME_HAMBURGUERS)),h.getString(h.getColumnIndex(DbHelper.VALOR_HAMBURGUERS))));
h.moveToNext();
}
defineAdapter2(itens);
}
private void defineAdapter2(ArrayList<CardapioGetter> itens) {
listview_hamburguers = (ListView) findViewById(R.id.listview_hamburguers);
AdapterListCardapios adapter = new AdapterListCardapios(getApplicationContext(), itens);
listview_hamburguers.setAdapter(adapter);
listview_hamburguers.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
CardapioGetter itemValue = (CardapioGetter) listview_hamburguers.getItemAtPosition(position);
}
});
}
Layout has the 4 textviews that i replace with data from database.
I want to split the 2 from the botton into a new listview.

the adapterlist class that i am using. setting itens to textviews.
the text views that i want separate on the listview.
public class AdapterListCardapios extends BaseAdapter{
private LayoutInflater mInflater;
private ArrayList<CardapioGetter> itens;
public AdapterListCardapios(Context context, ArrayList<CardapioGetter> itens) {
//Itens que preencheram o listview
this.itens = itens;
//responsavel por pegar o Layout do item.
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return itens.size();
}
/**
* Retorna o item de acordo com a posicao dele na tela.
*/
public CardapioGetter getItem(int position) {
return itens.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View view, ViewGroup parent) {
//Pega o item de acordo com a posição.
CardapioGetter item = itens.get(position);
//infla o layout para podermos preencher os dados
view = mInflater.inflate(R.layout.textview_cardapios, null);
((TextView) view.findViewById(R.id.textview_nomehamburguer)).setText(item.getNome_hamburguers());
((TextView) view.findViewById(R.id.textview_valorhamburguer)).setText("R$ "+ item.getValor_hamburguers());
((TextView) view.findViewById(R.id.textview_nomebebida)).setText(item.getNome_bebidas());
((TextView) view.findViewById(R.id.textview_valorbebida)).setText("R$ "+ item.getValor_bebidas());
return view;
}
What I want is. 1 listview with drinks and 1 listview with food on the same activity. thanks

CriarInterface p = new CriarInterface();
new Thread(p).start();
}
public class CriarInterface implements Runnable {
#Override
public void run() {
preencheLista();
preencheLista2();
}
}
worked.

Why is the dialog design inconsistent on the device?

I designed dialog and assigned it a file named XML layout with a set of elements and then created a function to show it from within fragment. It appeared on the emulator screen well but it did not appear the same on the device.
What are the appropriate adjustments to be shown on the device well?

Android - ArrayAdapter toggle ImageButton src between Play and Pause in ListView

I am still learning android. Here I need help to toggle between Play and Pause source in ImageButton in the ListView.
There should be only one song in Play state at a time. So if clicked other should stop.

Use a variable to store current playing items index
SongAdapter {
int playingIndex = -1 //-1 means no song is playing
.
.
.
}
Set play/pause drawable based on playingIndex and set the playingIndex in the songPlayButton.setOnClickListener
public View getView(final int position, ...) {
if(playingIndex == position)
songPlayButton.setImageResource(R.drawable.ic_play_black_24dp);
else
songPlayButton.setImageResource(R.drawable.ic_pause_black_24dp);
songPlayButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(position == playIndex)
playIndex = -1;
else
playIndex = position;
notifyDataSetChanged();
}
});
}
It should get the job done. But it forces a redraw of all rows. In RecyclerView there is the notifyItemChanged method which can force redraw on single item.
You may try using the method here to update single row https://stackoverflow.com/a/3727813/4907678
My suggestion is migrating to RecyclerView and using notifyItemChanged.
cheers!

Custom GridView Adapter not displaying

I'm creating a list of "channels" on an app that users can select. I want them in a grid view, (kind of like clickable tiles). There are supposed to be two separate Grids on this Fragment - default channels (channelListSupplied) and ones that the user will have to request subscriptions to (channelListEarned).
I used a custom adapter that I got from another answer here on SO, but I can't get it to work because it's in a Fragment instead of in the Activity, and I'm sure there's some reference I'm not passing correctly.
Below is a list of the relevant pieces of Java and XML...
FragmentChannels.java: (fragment to MainActivity.java)
public class FragmentChannels extends Fragment implements FragmentManager.OnBackStackChangedListener {
ViewGroup container;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
...
final JSONObject channelList = data.getJSONObject("channels");
final JSONArray channelListSupplied = channelList.getJSONArray("supplied");
final JSONArray channelListEarned = channelList.getJSONArray("earned");
GridView channelViewSupplied = (GridView) view.findViewById(R.id.channel_grid_supplied);
GridView channelViewEarned = (GridView) view.findViewById(R.id.channel_grid_earned);
if (Session.getSessionVar("canHasSpecial").equals("1")) {
FragmentChannels.this.createGridView(channelViewEarned, channelListEarned, FragmentChannels.this.container);
}
FragmentChannels.this.createGridView(channelViewSupplied, channelListSupplied, FragmentChannels.this.container);
...
return view;
}
public void createGridView(final GridView gridView, JSONArray list, final ViewGroup container) throws JSONException {
final String[] gridList = new String[list.length()];
final Activity activity = getActivity();
for (int i = 0; i < list.length(); i++) {
JSONObject channelData = (JSONObject) list.get(i);
gridList[i] = channelData.getString("source_name");
}
activity.runOnUiThread(new Runnable() {
#Override
public void run() {
gridView.setAdapter(new GridViewAdapter(activity, gridList, container));
}
});
}
public boolean createChannelMenu(Menu menu) {

inflater.inflate(R.menu.menu_channels, menu);

As of now, nothing displays on the Fragment except the "My Channels" TextView.
I greatly appreciate any help!

Fixed.
I changed the line:
gridView = inflater.inflate(R.layout.grid_item_layout, this.container);
To:
gridView = inflater.inflate(R.layout.grid_item_layout, null);
in the GridViewAdapter.java class.

Adding Custom Header to List Fragment in Android

I am trying to add a custom header that isnt clickable but will have a checkbox that will "check all" checkboxes under it.
This is my List Fragment
public class AssesmentListFragment extends ListFragment {
private static String BUNDLE_KEY_APPLICATION = "LIST_ITEM";
FastAssesmentListAdapter adapter;
View listHeader;
public AssesmentListFragment() {}
public AssesmentListFragment(Data[] data) {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Data[] assestments = {new Data("Assesment ID","Name", "Date"), new Data("123456", "Assestment 2", "9/12/12"),
new Data("345672", "Assesment 3", "9/13/12"), new Data("566893", "Assesment 4", "9/14/12")};
//This is the part that makes the app crash
View header = getActivity().getLayoutInflater().inflate(R.layout.list_adapter_assesments, null);
ListView listView = getListView();
listView.addHeaderView(header);
adapter = new FastAssesmentListAdapter(getActivity(), assestments);
setListAdapter(adapter);
updateList(assestments);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
private void updateList(Data[] assestments) {
// NOTE: addAll is not being used to support pre-honeycomb devices
synchronized(adapter) {
adapter.clear();
adapter.addAll(assestments);
adapter.notifyDataSetChanged();
}
}
#Override
public void onListItemClick(ListView parentView, View selectedItemView, int position, long id) {
String model = (String) parentView.getItemAtPosition(position);
((FacilityActivity) getActivity()).onItemSelected(model);
}
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
//outState.putInt("curChoice", mCurCheckPosition);
}
}
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:layout_width="0dp"

android:layout_weight="4"
android:textColor="#color/defaultTextColor"

android:textSize="28sp"

<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"

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"?>
