点击手机状态栏Notification,弹出 AlertDialog的方法
一、实现的思路
点击Notification,跳转到一个空白的activity,在空白的activity种弹出AlertDialog ,然后finish()。
Notification的使用方法,1.通过系统服务拿到NotificationManager。2.使用NotifiactionManager的notify方法
二、代码如下
public class NotificationTest extends Activity
{
static final int NOTIFICATION_ID = 0x1123;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//获取应用界面中的Button对象
Button bn = (Button) findViewById(R.id.bn);
//为按钮的单击事件绑定事件监听器
bn.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View source)
{
//创建一个启动其他Activity的Intent
Intent intent = new Intent(NotificationTest.this, OtherActivity.class);
PendingIntent pi = PendingIntent.getActivity(NotificationTest.this , 0, intent , 0);
//创建一个Notification
Notification notify = new Notification();
//为Notification设置图标,该图标显示在状态栏
notify.icon = R.drawable.notify;
//为Notification设置文本内容,该文本会显示在状态栏
notify.tickerText = "启动其他Activity的通知";
notificationManager.notify(NOTIFICATION_ID, notify);
}
});
}
}
public class OtherActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// 设置该Activity显示的页面
setContentView(R.layout.other);
NotificationManager notificationManager = (NotificationManager)
getSystemService(NOTIFICATION_SERVICE);
//取消通知
notificationManager.cancel(NotificationTest.NOTIFICATION_ID);
new AlertDialog.Builder(OtherActivity.this).setTitle("选择文件")
.setMessage("确认选择该文件?")
.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
//获取系统的NotificationManager服务
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
//取消通知
notificationManager.cancel(NOTIFICATION_ID);
finish();
}
})
.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(OtherActivity.this, "取消选择",Toast.LENGTH_SHORT).show();
finish();
}
}).show();
}
