listview not clickable

[Astha Sharma]

Hello,
I am developing an app using ListView but ListView's onClick event is not working. I'v searched a lot on google but not getting the solution. Tried all ways of building a list, but nothing works. Help needed. This is the java code-

public class MainActivity extends Activity implements OnClickListener, OnItemClickListener{
        private static final int REQUEST_CODE = 0;
	Button b1;
	ListView lv1;
	String bookName;
	static int pageCount;
	ImageView iv;
	static FileHandler fh=null;
	static String PATH= "data/data/sharma.astha.book.store2/books";
	public static TextView bookMenu;
	Context context =this;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        b1=(Button)findViewById(R.id.b1);
        b1.setOnClickListener(this);
        lv1=(ListView)findViewById(R.id.lv1);
        lv1.setOnItemClickListener(this);
        Log.d("1","oncreate");
        fh= new FileHandler();
		ArrayList<String> folders=  new ArrayList<String>();
		folders=fh.updateBookList();
		Log.d("1","result after updateBookList");
		if(folders!=null && folders.size()>0)
		{
			MyBookList myContactListAdapter = new MyBookList(folders, MainActivity.this);
			Log.d("1","folder"+folders.size());
			lv1.setAdapter(myContactListAdapter);
		}
		
    }

    public void onClick(View v) {
		// TODO Auto-generated method stub
		Log.d("1","onclick");
	    Intent i=new Intent(this, BookName.class);
	   	startActivityForResult(i, REQUEST_CODE);
	} 
    
    protected void onActivityResult(int requestCode, int resultCode, Intent data)
    {
    	Log.d("1","onactivityresult" );
    	if(requestCode==REQUEST_CODE)
    	{
    		Log.d("1","onrequest code verified "+resultCode);
    		if(resultCode==-2)
    		{
    			try
    			{
        			Log.d("1","result after enter book name "+bookName);
        			Bundle b=data.getExtras();
            		bookName= b.getString("bookName");
            		pageCount=fh.pageCount(bookName);
            		Log.d("1","pageCount= "+pageCount);
            		Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
            		//Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

            		String newPath = PATH+"/"+bookName+"/"+pageCount+".jpg";
            		Log.d("1",newPath);
            		File file = new File( newPath );
            		file.mkdirs();
            		Uri outputFileUri = Uri.fromFile( file );
            		//String absoluteOutputFileUri = file.getAbsolutePath();

            		intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
            		startActivityForResult(intent, 0);
    			}
    			catch(Exception e)
    			{
    				Log.d("1","exotn in path"+e.getMessage());
    				e.printStackTrace();
    			}
    		}
    		else
    		{
    			fh= new FileHandler();
    			ArrayList<String> folderName=fh.updateBookList();
    			Log.d("1","result after capture"+folderName.size());
    			MyBookList myContactListAdapter = new MyBookList(folderName, context);
    			lv1.setAdapter(myContactListAdapter);
    		}
    		
    	}
    	
    }

	public void onItemClick(AdapterView<?> arg0, View arg1, int pos, long arg3) {
		// TODO Auto-generated method stub
		Log.d("1", "onItemClick");
		fh=new FileHandler();
		try
		{
			String bookName= arg0.getItemAtPosition(pos).toString();
			fh.showBookPages(bookName);
		}
		catch(Exception e)
		{
			Log.d("1", "msg "+e.getMessage());
		}
		
	}


	
}
