I want to create a list menu with action bar, therefore I can't use ListActivity. The following code I have created but no list is shown up when I test it:
public class MainActivity extends AppCompatActivity {
ListView RecordList;
ArrayList<String> sectionArr;
ListAdapter adapter1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getRecordSet(); //A procedure to get list from SQLite DB (tested ok)
adapter1 = new CardListAdapter(this, sectionArr);
RecordList = (ListView)findViewById(R.id.listSet);
RecordList.setAdapter(adapter1);
RecordList.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View view, int position,
long id)
{
}
});
}...
In my custom adapter, the code is:
class CustomAdapter extends ArrayAdapter<String>{
public CustomAdapter(Context context, ArrayList<String> strArr) {
super(context, R.layout.custom_row, strArr);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View rowView = convertView;
int[] colors = new int[] {0x30A1B6AE, 0x30ECE7E7};
int colorPos = position % colors.length;
if (rowView==null) {
LayoutInflater inflator = LayoutInflater.from(getContext());
rowView = inflator.inflate(R.layout.custom_row, parent, false);
rowView.setBackgroundColor(colors[colorPos]);
}
String singleMenuItem = getItem(position);
TextView menuItemText = (TextView) rowView.findViewById(R.id.idItem);
menuItemText.setText(singleMenuItem);
return rowView;
}
#Override
public void notifyDataSetChanged() {
super.notifyDataSetChanged();
}
}
And the layout is:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.lusterview.studycards.MainActivity" >
<ListView
android:id="#+id/listSet"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_margin="10dp"
android:cacheColorHint="#android:color/black" >
</ListView>
Please advise.
Thanks in advance.

I have created a custom ListView, where the layout is definited in two XML, one which contain the definition of the ListView in a layout
For example activity_main.xml :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<LinearLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/myListView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
</RelativeLayout>
The other part of the XML is in another file, for example custom_list.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/list_row_selector">
<LinearLayout
android:id="#+id/photoList"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/takePhoto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="centerCrop"
android:src="#drawable/camera"/>
</LinearLayout>
</RelativeLayout>
In my activity i have declared actvivity_main.xml as main layout:
public class MainActivity extends AppCompatActivity{
private List<CustomRow> imageList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.cmp_details);
/* Initialization structures, variable, ecc */
ListView lv = (ListView) findViewById(R.id.imageList);
adapter = new CustomList(this, imageList);
lv.setAdapter(adapter);
}
/* Add element list in ListView */
private void addList(int idC){
CustomRow cr = new CustomRow();
cr.setId(idC);
cr.setTitle("xxx "+ (idC+1));
cr.setThumbnailUrl(R.drawable.no_image);
imageList.add(cr);
adapter.notifyDataSetChanged();
}
private void takePhoto(){
//Do something
}
}
Custom List.java
public class CustomList extends BaseAdapter {
private Activity activity;
private LayoutInflater inflater;
private List<CustomRow> ListItem;
private ImageLoader imageLoader = AppController.getInstance().getImageLoader();
public CustomList(Activity activity, List<CustomRow> listPhotoItems) {
this.activity = activity;
this.ListItem = listPhotoItems;
}
#Override
public int getCount() {
return ListItem.size();
}
#Override
public Object getItem(int location) {
return ListItem.get(location);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (inflater == null)
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.custom_list, null);
if (imageLoader == null)
imageLoader = AppController.getInstance().getImageLoader();
ImageView thumbNail = (ImageView) convertView.findViewById(R.id.thumbnail);
TextView title = (TextView) convertView.findViewById(R.id.title);
CustomRow m = ListItem.get(position);
thumbNail.setImageResource(m.getThumbnailUrl());
title.setTag(m.getId());
title.setText(m.getTitle());
return convertView;
}
}
Now I have to implement the OnClickListener of takePhoto, how I can do this ?
How I can bind onClickListener from the activity ?
I tried this solution but not work...
you could use setonitemclicklistener
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
imageList.get(position); // here you will get the clicked item from
//your imagelist and you can check by getting a title by using this
String title= imageList.get(position).getTitle();
if(title.equals("you title to match")){
//do your action or you can get a particular position and click there
}
}
});
This is the final solution, I have solve my problem with this code:
lv.setAdapter(adapter);
lv.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
View convertView = v;
final ImageView photo = (ImageView) convertView.findViewById(R.id.takePhoto);
photo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(CmpDetails.this, "Click", Toast.LENGTH_SHORT).show();
}
});
return false;
}
});
tv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
list.get(position);
String str= list.get(position).getTitle();
if(str.equals("")){
//put your code here
}
}
});
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
TextView tv = (TextView) v.findViewById(R.id.textView1);
tv.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//do your code on click event
}
});
return super.getView(position, convertView, parent);
}
I am currently working on a very basic android application and have encountered an obstacle I cannot solve on my own.
In my application I want to have a start screen with a ListView. In each Line of this ListView there should be a Button and a TextView. I want to have approximately 5 Lines. When you click on each of the Button you should be able to get to different Activities. How do I do that? I read something about adapters but I am still not sure how to build this.
Here's my xml code for the TextView and the Button:
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/textView"
android:id="#+id/rl01">
<TextView
android:layout_width= "wrap_content"
android:layout_height="50dp"
android:id="#+id/text01"
android:text="hello"
android:textSize="24dp"
android:textColor="#color/abc_search_url_text_normal"
android:paddingRight="#dimen/activity_horizontal_margin"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="50dp"
android:layout_toRightOf="#id/text01"
android:text="Press Me!"
/>
</RelativeLayout>
The xml layout you have posted, will be used as each listview item.
Step 1:
Create a class which extends BaseAdapter;
public class CustomAdapter extends BaseAdapter
{
Context con;
String[] data;
public CustomAdapter (Context context, String[] data)
{
this.con = context;
this.data = data;
}
#Override
public int getCount() {
return data.length;
}
#Override
public Object getItem(int position) {
return data[position];
}
#Override
public long getItemId(int position) {
return 0;
}
//this method will be called for every item of your listview
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) con.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView= inflater.inflate(R.layout.customview, parent, false);
TextView text = (TextView) view.findViewById(your text view id); //recognize your view like this
text.setText(data[position]);
return convertView;
}
}
Step 2:
In your activity, recognize your listview:
yourListViewReference = (ListView) findViewById(R.id.your_list_view_id);
And initialize String array:
String[] data = {"item 1", "item2", "item3"}; //how many items you want
And then create instance of custom adapter you created, and set it to listview:
CustomAdapter ad = new CustomAdapter(this, data);
yourListViewReference.setAdapter(ad);
And sorry for my bad english. I am actually working on it.
This article from Vogella is really useful for what you want to do.
Basically, you'll create an Adapter that extends the BaseAdapter class as follows:
public class Adapter extends BaseAdapter {
private List<Item> mItems;
private Context mContext;
public EventAdapter(Context context, List<Event> items) {
mContext = context;
mItems = items;
}
public View getView(int position, View convertView, ViewGroup parent) {
// This recycles your view and prevents constant inflation, which can really hit your performance.
View rowView = convertView;
if (rowView == null) {
ViewHolder viewHolder = new ViewHolder();
rowView = inflater.inflate(R.layout.yourLayout, parent, false);
viewHolder.text = (TextView) rowView.findViewById(R.id.yourTextViewId);
viewHolder.button = (Button) rowView.findViewById(R.id.yourButtonId);
rowView.setTag(viewHolder);
}
ViewHolder holder = (ViewHolder) rowView.getTag();
// Get the correct item by position
Item item = item.get(position);
// Update the row layout with your item data
holder.text.setText(item.text);
holder.button.setButton(item.button);
// Return your row view
return rowView;
}
#Override
public int getCount() {
return mItems.size();
}
#Override
public Object getItem(int position) {
}
#Override
public long getItemId(int position) {
}
static class ViewHolder {
public TextView text;
public Button button;
}
Afterwards you just need to set this adapter to your ListView or RecyclerView by doing
listView.setAdapter(new Adapter(this, items));
I would write a simple example:
You dont need a button in listview row, just implement onItemClick();
main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<ListView
android:id="#+id/custom_list"
android:longClickable="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
list_row.xml
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/textView"
android:id="#+id/rl01">
<TextView
android:layout_width= "wrap_content"
android:layout_height="50dp"
android:id="#+id/text01"
android:text="hello"
android:textSize="24dp"
android:textColor="#color/abc_search_url_text_normal"
android:paddingRight="#dimen/activity_horizontal_margin"
/>
MainActivity.java
oncreate()
{
....
lv1 = (ListView) result.findViewById(R.id.custom_list);
String[] listdata = {"txt1", "txt2", "txt3", "txt4", "txt5"};
ListAdapter listAdapt = new ListAdapter(this, listdata );
lv1.setAdapter(listAdapt);
lv1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> a, View v, int position, long id) {
//do ur work here when list row selected
}
});
..
}
ListAdapter.java
public class ListAdapter extends BaseAdapter {
String[] listData;
private LayoutInflater layoutInflater;
public CustomListAdapter(Context aContext, String[] listData) {
this.listData = listData;
layoutInflater = LayoutInflater.from(aContext);
}
#Override
public int getCount() {
return listData.size();
}
#Override
public Object getItem(int position) {
return listData.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.list_row, null);
TextView tv1 = (TextView)convertView.findViewById(R.id.text01);
tv1.setText(listData.[position]);
return convertView;
}
I made a listview in a fragment. Now I need to add a simple icon to the listview items. The icon must be the same on every item. This will be a simple arrow (imageview).
Is this possible with the listview I made? And if yes, how do I do it?
So like this format:
My text here --space--space-- >
The code for the fragment:
public class BiblioFragment extends Fragment {
final String[] items = new String[] { "Astma en alcohol", "Astma en huisdieren", "Astma en lichaamsgewicht",
"Astma en ouder worden", "Astmamedicatie", "Bekende mensen met astma", "Longfunctieonderzoek", "Reizen en vakantie",
"Sociaal leven", "Weetjes over astma", "Enzovoort", "Enzovoort", "Enzovoort" };
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_biblio, container, false);
ListView list = (ListView)view.findViewById(R.id.listView1);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, items);
list.setAdapter(adapter);
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Log.v("TAG", "CLICKED row number: " + arg2);
Intent myIntent = new Intent(getActivity(), BiblioDetail.class);
myIntent.putExtra("welkerij", arg2);
startActivity(myIntent);
}
});
return view;
}
}
My XML for that fragment:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#ffffff">
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
</ListView>
</LinearLayout>
In onCreateView
ListView list = (ListView)view.findViewById(R.id.listView1);
CustomAdapter cus = new CustomAdapter(getActivity(),items);
list.setAdapter(cus);
Use a custom adapter
public class CustomAdapter extends BaseAdapter {
String items[];
LayoutInflater mInflater;
public CustomAdapter(Context context, String[] items) {
mInflater = LayoutInflater.from(context);
this.items = items;
}
#Override
public int getCount() {
return items.length;
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if(convertView ==null)
{
convertView = mInflater.inflate(R.layout.list_item,parent,false);
holder = new ViewHolder();
holder.tv = (TextView) convertView.findViewById(R.id.textView1);
holder.iv = (ImageView) convertView.findViewById(R.id.imageView1);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
holder.tv.setText(items[position])
// use holder.iv to set whatever image you want according to the position
return convertView;
}
static class ViewHolder
{
ImageView iv;
TextView tv;
}
}
list_item.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="42dp"
android:layout_marginTop="32dp"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="#+id/imageView1"
android:layout_marginLeft="64dp"
android:layout_marginTop="14dp"
android:layout_toRightOf="#+id/imageView1"
android:text="TextView" />
</RelativeLayout>
Snap
Edit:
If you feel this is over kill you can use a compound textview with image on the left and text on the right.
In the above I have used list_item.xml which is a custom layout. I inflate that layout in getView of custom adapter. I set the text to textview. I have set the default launcher icon to imageview. You can change it though.
I have also used a ViewHolder

I have created a listview using following tutorial link http://www.ezzylearning.com/tutorial.aspx?tid=1763429
Outcome of this is, List of Activity as below image
Now, I want to navigate to different activity screen by clicking on individual row. I do have idea of navigating to next screen, However I'm not able to find the correct position of each row. I don't have much knowledge of android so please bare with my question if it is too silly.

You need to attach OnItemClickListener
listView1.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView <?> adapterView, View view, int position, long id) {
// position is index of the row that was clicked
}
});
where is listView1.setOnItemClickListener ? have you set setOnItemClickListener to listView1?.and in below code onItemClick have position.
listView1.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,long id) {
}
});
You should do something like this
listView1.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) { //do something
}
});
use setOnItemSelectedListener with list http://developer.android.com/reference/android/widget/AdapterView.OnItemSelectedListener.html
listView1.addHeaderView(header);
listView1.setAdapter(adapter);
listView1.setOnItemSelectedListener(
new OnItemSelectedListener() {
#Override
public void onItemSelected(
AdapterView<?> parent, View view, int pos, long id
) {
//where pos is your index
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {}
}
);
Try this way...
listView1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int position, long arg3) {
Toast.makeText(context, position+"", Toast.LENGTH_LONG).show();
Intent go_detail_Activity_Intent= new Intent(context,Target_Activity.class);
go_detail_Activity_Intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
context.startActivity(go_detail_Activity_Intent);
}
});
I think it help you.
I'm trying to place a spinner inside a list view item in android. The problem is this seems to prevent the row from being highlighted during a press and the onItemClickListener is not getting called by the ListView. Basically I am trying to mimic the functionality in the Google Music app. Does anyone know how to do this? This is the code I have been trying (I know it may not be the best... just throwing together a quick sample which shows the problem):
Activity:
public class ListViewTestActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ListView listView = (ListView) findViewById(R.id.listView1);
DataHolder data = new DataHolder(this);
DataHolder data1 = new DataHolder(this);
DataHolder data2 = new DataHolder(this);
DataHolder data3 = new DataHolder(this);
DataHolder data4 = new DataHolder(this);
DataAdapter d = new DataAdapter(this, R.layout.rowview, new DataHolder[] { data, data1, data2, data3, data4 });
listView.setAdapter(d);
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Log.e("ERROR", "look at me!");
}
});
}
}
public class DataHolder {
private int selected;
private ArrayAdapter<CharSequence> adapter;
public DataHolder(Context parent) {
adapter = ArrayAdapter.createFromResource(parent, R.array.choices, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
}
public ArrayAdapter<CharSequence> getAdapter() {
return adapter;
}
public String getText() {
return (String) adapter.getItem(selected);
}
public int getSelected() {
return selected;
}
public void setSelected(int selected) {
this.selected = selected;
}
}
This is the list adapter:
public class DataAdapter extends ArrayAdapter<DataHolder> {
private Activity myContext;
public DataAdapter(Activity context, int textViewResourceId, DataHolder[] objects) {
super(context, textViewResourceId, objects);
myContext = context;
}
// We keep this ViewHolder object to save time. It's quicker than findViewById() when repainting.
static class ViewHolder {
protected DataHolder data;
protected TextView text;
protected Spinner spin;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = null;
// Check to see if this row has already been painted once.
if (convertView == null) {
// If it hasn't, set up everything:

Thanks for any help!
I had the same problem with ImageButton, and what was needed was to do
mImageButton.setFocusable(false);
I can't garantee it's the same for Spinner, but my money is on it.
Best regards.
