Android仿IOS自定义AlertDialog提示框

本文介绍的仿ios对话框的实现，先来看一下效果图

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 display display;
 private boolean showtitle = false;
 private boolean showmsg = false;
 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;
 }

 public alertdialog settitle(string title) {
  showtitle = true;
  if ("".equals(title)) {
   txt_title.settext("标题");
  } else {
   txt_title.settext(title);
  }
  return this;
 }

 public alertdialog setmsg(string msg) {
  showmsg = true;
  if ("".equals(msg)) {
   txt_msg.settext("内容");
  } else {
   txt_msg.settext(msg);
  }
  return this;
 }

 public alertdialog setcancelable(boolean cancel) {
  dialog.setcancelable(cancel);
  return this;
 }

 public alertdialog setpositivebutton(string text,
   final onclicklistener listener) {
  showposbtn = true;
  if ("".equals(text)) {
   btn_pos.settext("确定");
  } else {
   btn_pos.settext(text);
  }
  btn_pos.setonclicklistener(new onclicklistener() {
   @override
   public void onclick(view v) {
    listener.onclick(v);
    dialog.dismiss();
   }
  });
  return this;
 }

 public alertdialog setnegativebutton(string text,
   final onclicklistener listener) {
  shownegbtn = true;
  if ("".equals(text)) {
   btn_neg.settext("取消");
  } else {
   btn_neg.settext(text);
  }
  btn_neg.setonclicklistener(new onclicklistener() {
   @override
   public void onclick(view v) {
    listener.onclick(v);
    dialog.dismiss();
   }
  });
  return this;
 }

 private void setlayout() {
  if (!showtitle && !showmsg) {
   txt_title.settext("提示");
   txt_title.setvisibility(view.visible);
  }

  if (showtitle) {
   txt_title.setvisibility(view.visible);
  }

  if (showmsg) {
   txt_msg.setvisibility(view.visible);
  }

  if (!showposbtn && !shownegbtn) {
   btn_pos.settext("确定");
   btn_pos.setvisibility(view.visible);
//   btn_pos.setbackgroundresource(r.drawable.alertdialog_single_selector);
   btn_pos.setonclicklistener(new onclicklistener() {
    @override
    public void onclick(view v) {
     dialog.dismiss();
    }
   });
  }

  if (showposbtn && shownegbtn) {
   btn_pos.setvisibility(view.visible);
//   btn_pos.setbackgroundresource(r.drawable.alertdialog_right_selector);
   btn_neg.setvisibility(view.visible);
//   btn_neg.setbackgroundresource(r.drawable.alertdialog_left_selector);
   img_line.setvisibility(view.visible);
  }

  if (showposbtn && !shownegbtn) {
   btn_pos.setvisibility(view.visible);
//   btn_pos.setbackgroundresource(r.drawable.alertdialog_single_selector);
  }

  if (!showposbtn && shownegbtn) {
   btn_neg.setvisibility(view.visible);
//   btn_neg.setbackgroundresource(r.drawable.alertdialog_single_selector);
  }
 }

 public void show() {
  setlayout();
  dialog.show();
 }
}

调用方式：

  new alertdialog(this).builder().setmsg(msg)
  .setpositivebutton("确定", new onclicklistener() {
   @override
   public void onclick(view v) {

   }
  }).setnegativebutton("取消", new onclicklistener() {

   @override
   public void onclick(view arg0) {
    // todo auto-generated method stub
   }
  }).show();
