i am using the ListView method to search in a custom listview. I have made an image and textview as elements to search. However, the edittext in which i used as the search bar cant properly filter my items but when tested using only text it works. Is there a way that my codes could be corrected? it doesn't show any errors. The Image Shown shows that when i try to filter T it doesn't show temasek ;instead it shows only the first two elements.
MainActivity.java:
public class MainActivity extends Activity {
String[] schools = { "Elias Park Primary",
"Anderson Secondary",
"Temasek JC",
"Republic Poly",
"Nanyang Poly" ,
"Meridian JC",
"Temasek Poly",
"Ngee Ann Poly",
"Anglican High"
};
Integer[] imageId = {
R.drawable.eliaspark_pri,
R.drawable.anderson_sec,
R.drawable.temasek_jc,
R.drawable.republic_poly,
R.drawable.nyp,
R.drawable.mjc,
R.drawable.tp,
R.drawable.ngee_ann,
R.drawable.anglican_high
};
ListView list;
custom adapter1;
EditText inputSearch;

adapter1 = new custom(MainActivity.this, schools, imageId);
list.setAdapter(adapter1);

I added SearchView to ActionBar to search items in ListView. I created my own ListView. But when I debug the app and search something, nothing shown. Which part did I do a mistake? Can someone help me?

Here is my Custom List Adapter class
public class ListAdapter extends ArrayAdapter implements Filterable {
ListClass [] kayitliste;
int resource;
public ListAdapter(Context context, int resource, ListClass[] kayitliste) {
super(context, resource, kayitliste);

}
public void setResource(int resource) {

}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View satir;
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
satir = inflater.inflate(resource , null);
TextView kodu , aciklama;
kodu = (TextView) satir.findViewById(R.id.txtKodu);
aciklama = (TextView) satir.findViewById(R.id.txtAciklama);
ListClass list = kayitliste[position];
kodu.setText(list.getKodu());
aciklama.setText(list.getAciklama());
return satir;
}
Here is my onCreate method and implementation
ListView lv;
ListAdapter adapter;
ListClass[] kayitlar;
public void InitData(){
kayitlar = new ListClass[]{
new ListClass("1" , "Example Record1"),
new ListClass("2" , "Example Record2"),

#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent intent = new Intent(ServisFisi.this , KayitDetay.class);

And here is my code in Activity.

I want to click on a button inside an item of a ListView and it should have the same effect from clicking the whole item. But when I click button nothing happens, when I click image its all Okey. How to fix it?
I tried setting on the button:
android:focusable="true"
android:clickable="true"
I also experimented with android:descendantFocusability.
None of my tries made the buttons clickable.
my_item.xml

String abs=Integer.toString(position + 1);
holder.myButton.setText(s+ " number " + abs);

return rowView;
}
}
Please write onclicklistener on your button.
You just have to configure onClick method something like this:
findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//your code goes here
}
});
Put button click listener in your getView
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View rowView = convertView;
// reuse views
if (rowView == null) {
LayoutInflater inflater = context.getLayoutInflater();
rowView = inflater.inflate(R.layout.my_item, null);
// configure view holder
ViewHolder viewHolder = new ViewHolder();
viewHolder.myButton = (Button) rowView.findViewById(R.id.button);
viewHolder.image = (ImageView) rowView.findViewById(R.id.imageArrow);
viewHolder.myButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Button click functionalty here
});
rowView.setTag(viewHolder);
}
// fill data
ViewHolder holder = (ViewHolder) rowView.getTag();
String s = names[position];
String abs=Integer.toString(position + 1);
holder.myButton.setText(s+ " number " + abs);
holder.image.setImageResource(R.drawable.r_arr);
return rowView;
}
}
To make your both listview item and button clickable, do this.
make ListView focusable android:focusable="true"
Button not focusable in your custom listview item android:focusable="false"
Method 1:
First replace button code in xml as below
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/button"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:focusable="false"
android:onClick="onClick"
android:focusableInTouchMode="false"
android:layout_toLeftOf="#+id/imageArrow"
android:layout_toStartOf="#+id/imageArrow"
/>
Then go to your activity and write code as below
public void onClick(View v)
{
super.onClick(v);
if (v.getId() == R.id.button)
{
//your code goes here
}
}
or You can add below peace of code in you oncreate
Method 2 :
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
It is not recommended to have two click listeners for a same row item in listview.
You can have in a Listview Custom Adapter. You can customize this according to your requirement.
or
You can have in your Activity / Fragment listview onclicklistener. This cannot be customized and when you click the whole row is selected.
I can't figure out why setOnItemClickListener doesn't work. I have ListView with custom ListItem layout,- and i'd like to start other activity when user click on row.
I saw lots of topic with this problem, but nothing helped.

add
android:descendantFocusability="blocksDescendants"
to your ListView's row root.
The implementation of getItemId of ArrayAdapter returns position and not the id of your RNote, so you probably want to override it to make it return the correct information
set android:focusable="false"
android:focusableInTouchMode="false" to all the clickable views (like button or editText) in your listView item

it is just simple implementation of list view and implementing onClick() on its elements to go to different Activity.thankful if anyone points out mistakes.
Your layout file named FragmentMain but You using activity_main as parameter of setContentView() method. Try to change to setContentView(R.layout.FragmentMain);
Please remove code from onCreate() and added in onCreateView(), as you are using fragment.
And your listview is also define in fragment_main.xml ,
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
final ListView listview = (ListView) rootView.findViewById(R.id.listView);

I'm attempting to launch an intent in my Home.java:
#Override
public void onVideoClicked(Video video) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(video.getUrl()));
startActivity(intent);
}
It should be initiated by:
package com.idg.omv.ui;
import com.idg.omv.domain.Video;
public interface VideoClickListener {
public void onVideoClicked(Video video);
}
which is initiated by listView.setOnVideoClickListener(this); in my Home.java
However I cannot seem to reach onVideoClicked when setting a breakpoint in Home.java and I'm unsure why.

Working Example:
http://blog.blundell-apps.com/click-item-in-a-listview-to-show-youtube-video/
If the List has clickable elements like ImageViewand Button, when you click on the list it is consumed by the ImageView and Button and your onitemClickListener is never called.
To make it work add android:clickable="false", android:focusable="false" and
android:focusableInTouchMode="false" to each of those Buttons and ImageViews in custom adapter view.
