Seems like you forgot to call setContentView(R.layout.your_layout); in your onCreate method

That button might not be part of the ListView, just of the main layout of that Activity.
If I understand what you're saying, you have a main view containing a ListView and a Button. If that affirmation is right, then you need to use an Activity instead of ListActivity or use :
mActivity= this ;
Button button = new Button(this);
button.setText("push me");
button.setLayoutParams(new AbsListView.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(mActivity, "push", Toast.LENGTH_SHORT).show();
}
});
getListView().addFooterView(button);
Be sure to call addFooterView(View v) before setAdapter(ListAdapter adapter)

Instead of use OnClickListener, please try to use onItemClikListener.
You are in a ListActivity, so I think (maybe I'm wrong) that what you want is to make call with the selected row. So remove bCall and its onClickListener and try
getListView().setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:3492395504"));
startActivity(callIntent);
}
});

You are getting an NPE because you are trying to do this:
bCall = (Button) findViewById(R.id.bCall);
When you haven't set a layout for the screen.
That button is in your list row layout so you need to set it's function in your list adapter.

If I'm understanding your code, you are kicking off an AsyncTask in onCreate, that sets the listAdaper within its onPostExecute method. Also, in onStart you are attempting to get the button bCall.
However, if onStart executes before your background task has completed, then you will not yet have set the adapter, thus your button will not exist and your call (Button) findViewById(R.id.bCall) will return null

The first textview takes up the full width of the horizontal LinearLayout so you can't see the second textview.
You can see the count by making the width of the textviews wrap_content but it probably won't match the design you're trying to achieve.

Step 1
- declare your activity inside of the manifest
Step 2
- starActivity(new Intent(getAcivity(), MyClass.class));
Step 3
- post your logcat if this didn't help while it should !
Edit: the issue seems that you are not setting a height to your layouts, base on your layout that you posted you have five layouts that are missing android:layout_height please add that and force close shall be gone.

please help me to solve this problem.thanking you in advance.

after getting the title as follows:
title= (TextView) findViewById(R.id.item_title);
use setText method to set the title as you wish.
I think it will solve your problem.

Button duplication in android when setting new text

I am working with the android support library, to be able to use fragments from Froyo, and the Sherlock extension, to show an ActionBar.
I have a fragment which shows three textViews and a button, and I want to be able to change the button text dinamically, depending on the content of the Intent. The problem is that when I call button.setText(String text), a second button appears. However, I've called button.getId() when clicking on each of them, and the Id is the same. I don't have a clue of why this is happening, so I'd appreciate some help.
The app is run on a Samsung Galaxy S, with Android 2.3.3. I can't upload a screen capture because I don't have enough reputation yet :(
This is the code:

Thanks!

I think I might have found the problem. I was calling
b = (Button) getSherlockActivity().findViewById(R.id.button);
but it should be
b = (Button) getView().findViewById(R.id.button);
With that change it works correctly

Cannot read EditText in fragment class

This is the code I use for declaring buttons in Fragments - maybe it can help you.
What I would do is access the inflated layout and then you should be able to access items underneath it. Let me know if that makes sense.
LinearLayout theLayout = (LinearLayout)inflater.inflate(R.layout.tab_frag1_layout, container, false);
// Register for the Button.OnClick event
Button b = (Button)theLayout.findViewById(R.id.frag1_button);
#Override
public void onClick(View v) {
Toast.makeText(Tab1Fragment.this.getActivity(), "OnClickMe button clicked", Toast.LENGTH_LONG).show();
}
});
return theLayout;
So maybe you should try this since you inflate your View as "addView"
name = (EditText) addView.findViewById(R.id.etProviderName);

The findViewById should not be called by the activity but by the enclosing view. You should have something like:
In the class
View aView;
In the method:
LayoutInflater inflater = getActivity().getLayoutInflater();
aView = inflater.inflate(R.layout.add_provider, null);
...
EditText name = (EditText) aView.findViewById(R.id.etProviderName);
I hope it helps.

nulPointException on button - android

Seems like you forgot to call setContentView(R.layout.your_layout); in your onCreate method

You are getting an NPE because you are trying to do this: bCall = (Button) findViewById(R.id.bCall); When you haven't set a layout for the screen. That button is in your list row layout so you need to set it's function in your list adapter.
