I was trying to implement simple customlistview.What i tried to do is to inflate a text and a picture inside each list row in the listview.I got no output i.e. layout was not inflating..I got a blank screen.I used 2 Java class and 2 xml files.Below is my code..Please let me know where is my mistake and what should i correct?
CListView.java
package com.example.customlistview;
public class Clistview extends Activity {
int p1[]={R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher};
String[] Shapes1={"circle","circle","circle","circle","circle"};
ListView lv;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_clistview);
lv=(ListView)findViewById(R.id.listView1);
CustomListViewAdapter clvadapter=new CustomListViewAdapter(Clistview.this,Shapes1,p1);
lv.setAdapter(clvadapter);
}
}
CustomListViewAdapter.java
package com.example.customlistview;
public class CustomListViewAdapter extends BaseAdapter {
Context context;
String shape1[];
int pic[];
public CustomListViewAdapter(Context c,String[] sh,int[] p)
{
this.context=c;
this.shape1=sh;
this.pic=p;
}
public int getCount() {
// TODO Auto-generated method stub
return 0;
}
public String getItem(int pos) {
// TODO Auto-generated method stub
return shape1[pos];
}
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return 0;
}
public View getView(int pos, View v, ViewGroup vg) {
// TODO Auto-generated method stub
View itemview=v;
TextView tv1;
ImageView im1;
if(itemview==null)
{
LayoutInflater inflater=(LayoutInflater)((Activity)context).getLayoutInflater();
itemview=inflater.inflate(R.layout.clistview1,vg,false);
}
tv1=(TextView)itemview.findViewById(R.id.textView1);
im1=(ImageView)itemview.findViewById(R.id.imageView1);
tv1.setText(shape1[pos]);
im1.setImageResource(pic[pos]);
return itemview;
}
}

Inside CustomListViewAdapter, change this
public int getCount() {
// TODO Auto-generated method stub
return shape1.length;
}
It is an important function that decides the number of items in a ListView.
public int getCount() {
// TODO Auto-generated method stub
return 0;
}
You are returning 0 .
Return pic.length or shape1.length as per your requirement.
public int getCount() {
return pic.length;
}
Method getCount() returns the number of items in the datatset for the adapter.
getCount()

I'm really new to android and I know you shouldnt paste whole codes but I honestly have no idea where the problem is.
Im trying to create a somewhat custom list view, with a text and an image, but keep geting this exception and have no idea how to solve it

so was hoping someone here could help me out. this is what my launcher activity looks like
public class MainActivity extends Activity {

CustomAdapter custom=new CustomAdapter(this, stringIds, imgIds);
list.setAdapter(custom);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
My CustomAdapter:

Here:

remove parent

or
finalView= inflater.inflate(R.layout.list_view_row, parent, false);
also use
setContentView(R.layout.activity_main);
before getting
ListView
In my application I am trying to create a ListView that contains an ImageView a TextView and a Button. I have created a separate XML file and drag all the above mentioned elements in that XML and in my main java file I have created an Object of BaseAdapter and in the getView() method I have declared these elements but when I run the application I cant see the list. I haven't used the BaseAdapter, so I am missing with some code in order to view the List. I also want to apply some operations on the button so please let me know that code also.
Code for my main.xml file:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>
Code for my list_item.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

<ImageView

android:text="Button" />
</LinearLayout>
Code for my main.java file:

#Override

**here i am setting two textview and one button**
((TextView) mView.findViewById(R.id.textView_appName)).setText(mAppList.getApp_Name());

**// register the button for clicklistener**

return mView;
}
#Override

}
and call this adapter class from your activity.
You are definitely missing lv.setAdapter(bs);
The app I'm struggling to make has a simple list and a button present in the bottom no matter what. My problem is that my custom BaseAdapter doesn't show elements. I know that since my elements are only a string I could use an ArrayAdapter, but the assignment requires it. The code:
class ListaOrase extends BaseAdapter{
private Activity context;
ArrayList<String> orase;
public ListaOrase(Activity context){
this.context=context;
orase=new ArrayList<String>();
}
public void add(String string){
orase.add(string);
}
public int getCount() {
// TODO Auto-generated method stub
return 0;
}
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return null;
}
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return 0;
}
public View getView (int position, View convertView, ViewGroup list) {
View element;
if (convertView == null)
{
LayoutInflater inflater = context.getLayoutInflater();
element = inflater.inflate(R.layout.lista, null);
}
else element = convertView;
TextView elementLista=(TextView)element.findViewById(R.id.elementLista);
elementLista.setText(orase.get(position));
return element;
}
}
public class WeatherAppActivity extends ListActivity {
Button buton;
ListaOrase lista;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
lista=new ListaOrase(this);
buton=(Button)findViewById(R.id.buton);
setListAdapter(lista);
lista.add("Bucuresti");
lista.add("Sibiu");
}
}
My XML files go like this:
main.xml -- for the Activity
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ListView
android:layout_width="fill_parent"
android:layout_height="wrap_content"

android:layout_alignParentTop="true"/>
<RelativeLayout

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<Button
android:id="#+id/buton"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:onClick="add"
android:text="Add"
android:layout_gravity=""
/>
</RelativeLayout>
</RelativeLayout>
lista.xml -- for the list
<?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" >
<TextView
android:id="#+id/elementLista"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>
The button "downstairs" opens a dialog that adds items to my list. It obviously doesn't work, but I think it's the BaseAdapter (ListaOrase) itself, as the intents throw no exceptions. I would be thankful if the items I hardcoded in would show up (Bucuresti and Sibiu).
What am I doing wrong?
Thank you very much! :)
Your code almost perfect issue is return orase.size() in getcount() method,you are returning 0, add unimplemented methods in ListaOrase class.
your ListaOrase should be like this:
class ListaOrase extends BaseAdapter{
private Activity context;
ArrayList<String> orase;
public ListaOrase(Activity context){
this.context=context;
orase=new ArrayList<String>();
}
public void add(String string){
orase.add(string);
}
public View getView (int position, View convertView, ViewGroup list) {
View element;
if (convertView == null)
{
LayoutInflater inflater = context.getLayoutInflater();
element = inflater.inflate(R.layout.lista, null);
}
else element = convertView;
TextView elementLista=(TextView)element.findViewById(R.id.elementLista);
elementLista.setText(orase.get(position));
Log.e("",orase.get(position));
return element;
}
public int getCount() {
// TODO Auto-generated method stub
return orase.size();
}
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
}
hope this helps
getCount method was really returning 0 so consquently getView() wasn't being called. When I changed to:
getcount() {
return arrayObject.Size();
}
