Question

I am getting null pointer exception,

due to failed to recognize layout parameter in the custom alert dialog.

So, If any one know this please help me…?

Thanks in advance…!

builder = new AlertDialog.Builder(this);
        builder.setView(getLayoutInflater().inflate(R.layout.custom_dialog, null));
        //AlertDialog dialog = new AlertDialog.Builder(this).create();
        //dialog.setContentView(R.layout.custom_dialog);
        dialog = builder.create();
        customDialogList = (ListView) dialog.findViewById(R.id.custom_list);
        customDialogList.setAdapter(customDialogAdapter); // here null pointer exception    
        dialog.setCancelable(true);
        dialog.show();

        builder.setView(customView);
        //AlertDialog dialog = new AlertDialog.Builder(this).create();
        //dialog.setContentView(R.layout.custom_dialog);
        dialog = builder.create();
        customDialogList = (ListView) customView.findViewById(R.id.custom_list);
        customDialogList.setAdapter(customDialogAdapter);   
        dialog.setCancelable(true);
