具体代码如下:

public class AlertDialog {
 private Context context;
 private Dialog dialog;
 private LinearLayout lLayout_bg;
 private TextView txt_title;
 private TextView txt_msg;
 private Button btn_neg;
 private Button btn_pos;
 private ImageView img_line;

 private boolean showPosBtn = false;
 private boolean showNegBtn = false;

 public AlertDialog(Context context) {
  this.context = context;
  WindowManager windowManager = (WindowManager) context
    .getSystemService(Context.WINDOW_SERVICE);
  display = windowManager.getDefaultDisplay();
 }

 public AlertDialog builder() {
  View view = LayoutInflater.from(context).inflate(
    R.layout.view_alertdialog, null);

  lLayout_bg = (LinearLayout) view.findViewById(R.id.lLayout_bg);
  txt_title = (TextView) view.findViewById(R.id.txt_title);
  txt_title.setVisibility(View.GONE);
  txt_msg = (TextView) view.findViewById(R.id.txt_msg);
  txt_msg.setVisibility(View.GONE);
  btn_neg = (Button) view.findViewById(R.id.btn_neg);
  btn_neg.setVisibility(View.GONE);
  btn_pos = (Button) view.findViewById(R.id.btn_pos);
  btn_pos.setVisibility(View.GONE);
  img_line = (ImageView) view.findViewById(R.id.img_line);
  img_line.setVisibility(View.GONE);

  dialog = new Dialog(context, R.style.AlertDialogStyle);
  dialog.setContentView(view);

  lLayout_bg.setLayoutParams(new FrameLayout.LayoutParams((int) (display
    .getWidth() * 0.80), LayoutParams.WRAP_CONTENT));

  return this;
 }

  return this;
 }

   }
  });
  return this;
 }

 private void setLayout() {
  if (!showTitle && !showMsg) {

   txt_title.setVisibility(View.VISIBLE);
  }

  if (showTitle) {
   txt_title.setVisibility(View.VISIBLE);
  }

   txt_msg.setVisibility(View.VISIBLE);
  }

  if (!showPosBtn && !showNegBtn) {

    }
   });
  }
