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();
