yesterday on the Internet, with the brothers to discuss the effect of clicking the screen broken, today simply take out time to tidy up, very simple Austrian,Basic idea: 1. Customize a view to show the broken effect 2. Add this view to the activity by Setcontentview (view); 3. Be careful to set the activity's theme to Android:theme= "@android: Style/theme.translucent.notitlebar" so that it will be more effective to play. First rewrite a view, let's call Customeview. It's fine to define yourself. The definition constructor is as follows: Public CustomView (Context context, AttributeSet Attrs) {super (context); This.setkeepscreenon (TRUE); This.setfocusable (TRUE); This.setlongclickable (TRUE); This.msoundpool = new Soundpool (5, Audiomanager.stream_system, 5); This.mSoundMap.put (1, msoundpool.load (context, R.RAW.CFOKWOWBFV, 1)); This.mbitmap = Bitmapfactory.decoderesource (Getresources (), r.drawable.screen); Mxpointlist = new arraylist<float> (); Mypointlist = new arraylist<float> (); }
Here a sound pool is declared (for tapping the screen, making a broken, lifelike effect), a bitmap that shows that the screen is broken in two lists, respectively.mxpointlistand themypointlist, which is used to save points of X and y when clicked.
Next, let's take a look at ontouchevent ()@OverridePublic Boolean ontouchevent (motionevent arg1) {//TODO auto-generated method stubswitch (arg1.getaction ()) {Case Motionevent.action_down:playSound ();//AudibleMxpointlist.add (Arg1.getx ());Mypointlist.add (Arg1.gety ());postinvalidate ();//Refresh Interfacemcount++;//The number of clicks, where,Mlength is the total numberif (MCount > Mlength) {mxpointlist.remove (0);mypointlist.remove (0);mlength++; }Break ;Case MOTIONEVENT.ACTION_UP:Break ;Case Motionevent.action_move:Break ;Default:Break ; }return super.ontouchevent (arg1); }
You can refer to the comments I wrote, and see that the last isOnDraw () method, this method is particularly important. @Override protected void OnDraw (canvas canvas) {super.ondraw (canvas); for (int i = 0; i < mxpointlist.size (); ++i) {//points how many times, the broken picture is displayed how many times Canvas.drawbitmap (Mbitmap, Mxpointlist.get (i)-MB Itmap.getwidth ()/2, Mypointlist.get (i)-mbitmap.getheight ()/2, NULL); } }
The following settings are then made in the OnCreate method in the activity to be referenced:
@Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); CustomView view = new CustomView (this, null); Setcontentview (view);
}
Also, don't forget to add <activity android:name= to the Mainfest file. Screencrashmainactivity "android:theme= "@android: Style/theme.translucent.notitlebar"Android:label= "@string/app_name" >
More realistic results. Hee Hee All right, finish the call!
