The implementation of the suspended window is implemented with a service, custom view, Activity

The permission used to implement the suspended window:

    <!--the permissions required for the 360 floating plugin--    <uses-permission android:name= "Android.permission.SYSTEM_ALERT_WINDOW"/>    <uses-permission android:name= "Com.android.vending.BILLING"/>

Registering services in a manifest file

<service android:name= "Com.pca.nettraffic.MserServes"/>

Implementation of the Code

1.Activity of source code

Package Com.pca.nettraffic;import Android.app.activity;import Android.content.intent;import android.os.Bundle; Import Android.view.view;import Android.view.view.onclicklistener;import Android.widget.button;public class Widgetmainactivity extends Activity {//a activityprivate button with only one button btn; @Overrideprotected void OnCreate (Bundle Savedinstancestate) {//TODO auto-generated method Stubsuper.oncreate (savedinstancestate); Setcontentview ( R.layout.activity_imitate_widget_main) btn = (Button) Findviewbyid (R.ID.BTN); Btn.setonclicklistener (new Onclicklistener () {@Overridepublic void OnClick (View v) {//TODO auto-generated method Stubfunclick ();}});} public void Funclick () {//button is clicked This.startservice (New Intent (Getapplicationcontext (), mserserves.class));//New Tableshowview (This). Fun (); If it is only activated in activity//When the activity is running to the background [suspend state, or destroy State] The view we set to the desktop will disappear//So here is the start of a service, the service creates the view that we need to display on the table, and register it on WindowManager this.finish ();}}

2.Service Source Code

Package Com.pca.nettraffic;import Android.app.service;import Android.content.intent;import android.os.IBinder; public class Mserserves extends service {   //Services//      This kind of pure egg is used only in order to open a service after the activity clicks the button             @Override Public      IBinder Onbind (Intent Intent) {          //TODO auto-generated method stub          return null;      }        public void OnCreate () {      //creates a service when a Tableshowview object is instantiated and calls his fun () method to register it on          WindowManager Super.oncreate ();          New Tableshowview (Getapplicationcontext ()). Fun ();          System.out.println ("Open mser service ...");          @Override public      int Onstartcommand (Intent Intent, int flags, int startid) {          //TODO auto-generated method stub< C16/>return Super.onstartcommand (Intent, flags, Startid);      }  }  

3. Custom View Source (Tableshowview extends view)

Package Com.pca.nettraffic;import Android.content.context;import Android.graphics.color;import Android.view.layoutinflater;import Android.view.motionevent;import Android.view.view;import Android.view.windowmanager;import Android.widget.toast;public class Tableshowview extends View {// If you want to display lyrics then inherit the TextView and copy the OnDraw method. Open a thread to constantly call the OnDraw method to change what you have written to inherit from TextView.//Here is a random integration from the view of the = = This is not the focus of CONTEXTC; windowmanagermwm;//windowmanagerwindowmanager.layoutparamsmwmparams;//windowmanager parameter viewwin;int tag = 0;int Oldoffsetx;int Oldoffsety;public Tableshowview (Context context) {//TODO auto-generated Constructor Stubsuper (context) ; c = Context;} public void Fun () {//Set load view WindowManager parameter MWM = (WindowManager) c.getsystemservice (context.window_service); win = Layoutinflater.from (c). Inflate (R.layout.activity_imitate_widget_ctrl_window, null); Win.setbackgroundcolor ( color.transparent);//This is a random loading of a layout file Win.setontouchlistener (new Ontouchlistener () {//touchscreen monitoring FLOATLASTX, lasty;public Boolean OnTouch (View V,Motionevent event) {Final int action = Event.getaction (); float x = Event.getx (); Float y = event.gety (); if (tag = = 0) {old Offsetx= mwmparams.x; Offset oldoffsety = mwmparams.y; Offset} if (action = = motionevent.action_down) {lastx = X;lasty = y;} else if (action = = motionevent.action_move) {mwmparams.x + = (int) (X-LASTX);//offset Mwmparams.y + = (int) (y-lasty);// Offset tag = 1;mwm.updateviewlayout (win, mwmparams);} else if (action = = motionevent.action_up) {int newoffsetx = Mwmparams.x;int newoffsety = mwmparams.y;if (Oldoffsetx = = NewO Ffsetx && oldoffsety = = newoffsety) {Toast.maketext (c), "You've ordered me ... Hurt!!!! ", 1). Show ();} else {tag = 0;}} return true;}}); WindowManager wm = MWM; Windowmanager.layoutparams wmparams = new Windowmanager.layoutparams (); mwmparams = Wmparams;wmparams.type = 2002; Type is the key, here's 2002 for the System Level window, you can also try 2003. Wmparams.flags = 40;//This sentence to set the desktop controllable wmparams.width = 50;wmparams.height = 50;wmparams.format =-3; Transparent Wm.addview (win, wmparams);//This is the key to the WindowManager to throw in the value just set//onlyAddView can be displayed on the page. Register to WindowManager win is to just load the layout,wmparams is just set the WindowManager parameter set// The effect is to register win with WindowManager and its parameters are wmparams set in the Hungry}}
