private void notification(String content, String number, String date) {
manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); // 获取系统的通知管理器
notification = new Notification(R.drawable.ic_menu_compose, content, System.currentTimeMillis()); //获取图标、内容、时间等等
notification.defaults = Notification.DEFAULT_ALL; // 使用默认设置（比如铃声、震动、闪灯）
notification.flags = Notification.FLAG_AUTO_CANCEL; // 但用户点击消息后，消息自动在通知栏自动消失
notification.flags |= Notification.FLAG_NO_CLEAR;// 点击通知栏的删除，消息不会依然不会被删除
Intent intent = new Intent(getApplicationContext(), ContentActivity.class); //跳转页面
intent.putExtra("content", content); //封装内容
intent.putExtra("number", number); //封装数字
intent.putExtra("date", date); //封装时间
pi = PendingIntent.getActivity(getApplicationContext(), 0, intent, 0);
notification.setLatestEventInfo(getApplicationContext(), number + "发来短信", content, pi);
manager.notify(0, notification); // 将消息推送到状态栏
/****************************************< 线程 >******************************************/
private class MyThread extends Thread {
public void run() {
String url = "http://110.65.99.66:8080/jerry/PushSmsServlet"; //定位服务器
while (flag) {//检查并判断标志位
System.out.println("发送请求");
try {
Thread.sleep(10000); // 每个10秒向服务器发送一次请求
} catch (InterruptedException e)
{
e.printStackTrace();
}
// 采用get方式向服务器发送请求
client.get(url, new AsyncHttpResponseHandler() {
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
try {
JSONObject result = new JSONObject(new String( responseBody, "utf-8"));
int state = result.getInt("state");
// 假设偶数为未读消息
if (state % 2 == 0) {
String content = result.getString("content");
String date = result.getString("date");
String number = result.getString("number");
notification(content, number, date);
}
} catch (Exception e) {
e.printStackTrace();
}
}
public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
Toast.makeText(getApplicationContext(), "数据请求失败", 0) .show();
}
});
}
三、清单文件中注册
3.1 service注册：
<service android:name=".PushSmsService"></service>
四、权限配置问题
4.1 由于通知信息使用到了手机的震动功能和网络访问，所以需要配置权限。
<uses-permission android:name="android.permission.VIBRATE"/> <!-震动权限->
<uses-permission android:name="android.permission.INTERNET"/> <!-网络权限->
五、再定义Activity
（用于用户点击下拉通知栏里的某条消息后，跳转到详细的消息界面）
public class ContentActivity extends Activity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_content);
Intent intent = getIntent();
TextView tv_content = (TextView) this.findViewById(R.id.tv_content);
TextView tv_number = (TextView) this.findViewById(R.id.tv_number);
TextView tv_date = (TextView) this.findViewById(R.id.tv_date);
if (intent != null) {
String content = intent.getStringExtra("content");
String number = intent.getStringExtra("number");
String date = intent.getStringExtra("date");
tv_content.setText("内容：" + content);
tv_number.setText("号码：" + number);
tv_date.setText("日期：" + date);
}
}
5.1 在清单文件中注册新的Activity
<activity android:name=".ContentActivity"></activity>
5.2 注意到上边的代码是需要服务器提供支持的，我们去新建一个简单的服务器，里边添加一个Servlet和一个实体类就可以了
public class PushSmsServlet extends HttpServlet {
private static int index = 1;
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
System.out.println(index);
// List<Sms> smsList = new ArrayList<Sms>();
Sms sms = new Sms(index, "傻逼" + index, "2016-08-08", "15208432222");
index++;
// smsList.add(sms);
// sms = new Sms(0, "傻逼", "2016-08-08", "15208432222");
// smsList.add(sms);
// sms = new Sms(1, "傻逼", "2016-08-08", "13522224444");
// smsList.add(sms);
response.setContentType("text/
html");
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("utf-8");
PrintWriter out = response.getWriter();
Gson gson = new Gson();
// 将Sms类的数据转换为json数据格式
String json = gson.toJson(sms);
out.write(json);
out.flush();
out.close();
}
//doPost
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
this.doGet(request, response);
}
/****************************************< 定义封装用于存放消息的类 >******************************************/
private int state;
private String content;
private String date;
private String number;
public Sms(int state, String content, String date, String number) {
super();
this.state = state;
this.content = content;
this.date = date;
this.number = number;
}
}
这部只是分核心代码，其余的就请自行扩充！
