i have created a CustomDialog. like this..

the xml is ..

and CustomDialogClass is

    import android.app.Activity;
import android.app.Dialog;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.widget.Button;
import android.widget.Toast;

import com.example.fragmentaltdd.R;

public class CustomDialogClass extends Dialog implements
android.view.View.OnClickListener {

    public Activity c;
    public Dialog d;
    public Button Post, Cancel,Upload;

    public CustomDialogClass(Activity a)
    {
        super(a);

        this.c = a;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);


        requestWindowFeature(Window.FEATURE_NO_TITLE);

        setContentView(R.layout.createpost);

        Post = (Button) findViewById(R.id.post_btn);

        Cancel = (Button) findViewById(R.id.cancel_btn);

        Upload = (Button)findViewById(R.id.upload_btn);

        Post.setOnClickListener(this);

        Cancel.setOnClickListener(this);

        Upload.setOnClickListener(this);

    }

    @Override
    public void onClick(View v)
    {
        switch (v.getId())
        {
            case R.id.post_btn:
              //c.finish();
                Toast.makeText(c, "Post button clikced", Toast.LENGTH_LONG).show();
              break;

            case R.id.upload_btn:
                 // c.finish();
                Toast.makeText(c, "Upload button clikced", Toast.LENGTH_LONG).show();
                  break;

            case R.id.cancel_btn:
              dismiss();
              break;

            default:
              break;
        }
        dismiss();
    }
}

And call it like this

    CustomDialogClass cdd = new CustomDialogClass(getActivity());//while calling from fragment

CustomDialogClass cdd = new CustomDialogClass(YourActivity.this);//while calling from Activity

            cdd.show();
