android - Handle custom view's different touch states -

i have custom view, extending relativelayout , using list item in listview. it's rectangle funky angle on left. depending on return in ontouchevent, can end in 2 possible states:

1. the list item display pressed state , return unpressed state not send click listview.
2. the list item remain in pressed state (and can't out) send click listview fine.

i have never done custom views of type before appreciate advice. assume i'm missing simple, i've spent way time on @ point go on without asking questions!

here's code:

public class listitembackgroundview extends relativelayout {     private final path path = new path();     private final paint brush = new paint(paint.anti_alias_flag);     private static int mbackgroundcolor = -1;     private static int mpressedbackgroundcolor = -1;     private static int mangleoffset = -1;      private boolean ispressed;      public listitembackgroundview(context context) {         super(context);         setwillnotdraw(false);     }      public listitembackgroundview(context context, attributeset attrs) {         super(context, attrs);         setwillnotdraw(false);     }      public listitembackgroundview(context context, attributeset attrs, int defstyle) {         super(context, attrs, defstyle);         setwillnotdraw(false);     }      @override     protected void ondraw(canvas canvas) {         super.ondraw(canvas);          final int w = canvas.getwidth();         final int h = canvas.getheight();          if (mbackgroundcolor == -1) {             mbackgroundcolor = getresources().getcolor(r.color.color_1);             mpressedbackgroundcolor = getresources().getcolor(r.color.color_2);             mangleoffset = getresources().getdimensionpixelsize(r.dimen.list_view_angle_offset);         }          path.moveto(0, 0);         path.lineto(mangleoffset, h * (0.35f));         path.lineto(0, h);         path.lineto(w, h);         path.lineto(w, 0);         path.lineto(0, 0);         path.close();          brush.setstyle(paint.style.fill);         brush.setcolor(ispressed ? mpressedbackgroundcolor : mbackgroundcolor);          canvas.drawpath(path, brush);     }      @override     public boolean ontouchevent(motionevent event) {         boolean result = super.ontouchevent(event);         switch (event.getaction()) {             case motionevent.action_down:                 ispressed = true;                 result = false;                 invalidate();                 break;             case motionevent.action_up:             case motionevent.action_cancel:                 ispressed = false;                 result = true;                 invalidate();                 break;         }         return result;     } } 

the solution use statelistdrawable background.

public class listitemstatelistdrawable extends statelistdrawable {     private final int mbackgroundcolor, mpressedbackgroundcolor, mangleoffset;     private final path path = new path();     private final paint brush_pressed = new paint(paint.anti_alias_flag);     private final paint brush = new paint(paint.anti_alias_flag);     private boolean isdrawn = false;     private boolean ispressed = false;      public listitemstatelistdrawable(int backgroundcolor, int pressedbackgroundcolor, int angleoffset) {         this.mbackgroundcolor = backgroundcolor;         this.mpressedbackgroundcolor = pressedbackgroundcolor;         this.mangleoffset = angleoffset;     }      @override     protected boolean onstatechange(int[] stateset) {         for(int st : stateset){             boolean pressed = st == android.r.attr.state_pressed;             boolean not_pressed = st == android.r.attr.statenotneeded || st ==  -android.r.attr.state_pressed ||                     st ==  android.r.attr.state_accelerated || st ==  android.r.attr.state_focused;             if(pressed || not_pressed){                 ispressed = pressed;                 invalidateself();                 break;             }         }         return super.onstatechange(stateset);     }      @override     public void draw(canvas canvas) {         if(!isdrawn){             final int w = canvas.getwidth();             final int h = canvas.getheight();              path.moveto(0, 0);             path.lineto(mangleoffset, h * (0.35f));             path.lineto(0, h);             path.lineto(w, h);             path.lineto(w, 0);             path.lineto(0, 0);             path.close();              brush.setstyle(paint.style.fill);             brush.setcolor(mbackgroundcolor);             brush_pressed.setstyle(paint.style.fill);             brush_pressed.setcolor(mpressedbackgroundcolor);              canvas.drawpath(path, brush);             isdrawn = true;         }else {             canvas.drawpath(path, ispressed ? brush_pressed : brush);         }     } }
