Android提示框与通知的使用

1.通知

Android 3.0以前使用的方法

            NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
            Notification notification = new Notification(R.drawable.dss,
                    "通知到了", System.currentTimeMillis());
            notification.flags = Notification.FLAG_AUTO_CANCEL;
            Intent intent = new Intent();
            PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                    intent, 0);
            notification.setLatestEventInfo(this, "标题", "内容", contentIntent);
            nm.notify(0, notification);

替代方法

            Intent intent = new Intent();
            PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                    intent, 0);
            Notification noti = new Notification.Builder(this)
                    .setTicker("通知到了")
                    .setContentTitle("标题")
                    .setContentText("内容")
                    .setAutoCancel(true)
                    .setContentIntent(contentIntent)
                    .setSmallIcon(R.drawable.dss)
                    .setLargeIcon(
                            BitmapFactory.decodeResource(getResources(),
                                    R.drawable.dss)).build();
            NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
            nm.notify(0, noti);

2.对话框

            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle("对话框标题");
            builder.setMessage("对话框内容");
            builder.setPositiveButton("确定", new OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    //Toast.makeText(getApplicationContext(), "确定被点击了", Toast.LENGTH_SHORT).show();
                }
            });
            builder.setNegativeButton("取消", new OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    //Toast.makeText(getApplicationContext(), "确定被点击了", Toast.LENGTH_SHORT).show();
                }
            });
            //禁止响应返回键
            builder.setCancelable(false);
            builder.create().show();

3.单选对话框

            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle("请选择：");
            final String[] items = {"喜欢", "不喜欢"};
            builder.setSingleChoiceItems(items, 0, new OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    //单击后退出单选对话框
                    dialog.dismiss();
                }
            });
            builder.create().show();

4.多选对话框

            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle("请选择你最爱吃的水果");
            final String[] items={"苹果","梨","菠萝","香蕉","黄瓜"};
            final boolean[] result =new boolean[]{true,false,true,false,false};
            builder.setMultiChoiceItems(items, result, new OnMultiChoiceClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                    //Toast.makeText(getApplicationContext(), items[which]+isChecked, 0).show();
                    result[which] = isChecked;
                }
            });
            builder.setPositiveButton("提交", new OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    StringBuffer sb = new StringBuffer();
                    for(int i=0;i<result.length;i++){
                        //if(result[i]){
                        //    sb.append(" " + items[i]);
                        //}
                    }
                    //Toast.makeText(getApplicationContext(), "您选中了"+sb.toString(), 0).show();
                }
            });
            builder.show();//作用同 builder.create().show();

5.带进度条的对话框

            final ProgressDialog pd = new ProgressDialog(this);
            pd.setTitle("警告");
            pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
            pd.setMax(100);
            pd.setMessage("正在处理数据，请稍等。。。");
            pd.show();
            new Thread(){
                public void run() {
                    for(int i = 0;i<100;i++){
                        try {
                            Thread.sleep(40);
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                        pd.setProgress(i);
                    }
                    pd.dismiss();
                };
            }.start();
