我构建了一个应用程序,该应用程序有一个活动,我想从点击状态通知图标开始。我想要发生的是我的活动,我设置为显示一个对话框,显示在设备上已经打开的任何应用程序的顶部。在没有主应用程序的情况下启动一个对话框
但现在发生的情况是,当单击通知图标时,对话框活动与其下面的应用程序主活动一起启动,如下图所示。

我怎样才能启动对话框,以便它显示了在当前的应用程序在屏幕上,我的主要活动将不启动?
主要活动:
public class mainActivity extends Activity {
public NotificationManager mNotificationManager;
private Button start;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
start = (Button) findViewById(R.id.start);
start.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent myIntent = new Intent(getApplicationContext(), servicetest.class);
startService(myIntent);
Log.d("start","sms");
Toast.makeText(SmseverywhereActivity.this, "Service Started",
Toast.LENGTH_LONG).show();
}
});
}
}
服务侦听通知新闻界,并开始对话活动:
public class servicetest extends Service{
public NotificationManager mNotificationManager;
public Intent dialogIntent;
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate() {
super.onCreate();
Log.d("servicetest","onCreate");
mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
showNotification();
}
private void showNotification(){
Notification not = new Notification(R.drawable.ic_launcher, "Application started", System.currentTimeMillis());
Intent myIntent = new Intent(this, dialogactivity.class);
myIntent.putExtra("isFullScreen", true);
myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, myIntent, Notification.FLAG_ONGOING_EVENT);
not.flags = Notification.FLAG_ONGOING_EVENT;
not.setLatestEventInfo(this, "Application Name", "Application Description", contentIntent);
mNotificationManager.notify(1, not);
}
}
Dialog activity:
public class dialogactivity extends Activity{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.dialogtest);
}
}
清单:
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name=".SmseverywhereActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:label="@string/app_name"
android:name="NewText"
android:theme="@android:style/Theme.Dialog"
android:launchMode="singleTask"
android:screenOrientation="user">
</activity>
<service android:enabled="true" android:name=".servicetest" />
