Android Development Square Fillet ListView code sharing _android

First look at the effect of the picture:

First, you have to write a class we named Cornerlistview

[Java]

Copy Code code as follows:

/**
* Rounded Corner ListView sample
* @Description: Rounded corner ListView Sample
* @FileName: Cornerlistview.java
*/
public class Cornerlistview extends ListView {
Public Cornerlistview {
Super (context);
}

Public Cornerlistview (context context, AttributeSet attrs, int defstyle) {
Super (context, attrs, Defstyle);
}

Public Cornerlistview (context context, AttributeSet Attrs) {
Super (context, attrs);
}

@Override
public boolean onintercepttouchevent (Motionevent ev) {
Switch (ev.getaction ()) {
Case Motionevent.action_down:
int x = (int) ev.getx ();
int y = (int) ev.gety ();
int itemnum = pointtoposition (x, y);

if (Itemnum = = adapterview.invalid_position)
Break
else{
if (itemnum==0) {
if (itemnum== (Getadapter (). GetCount ()-1)) {
Setselector (R.drawable.<span style= "COLOR: #ff0000" >app_list_corner_round</SPAN>);
}else{
Setselector (R.drawable.<span style= "COLOR: #ff0000" >app_list_corner_round_top</SPAN>);
}
}else if (itemnum== (Getadapter (). GetCount ()-1))
Setselector (R.drawable.<span style= "COLOR: #ff0000" >app_list_corner_round_bottom</SPAN>);
else{
Setselector (R.drawable.<span style= "COLOR: #ff0000" >app_list_corner_shape</SPAN>);
}
}

Break
Case MOTIONEVENT.ACTION_UP:
Break
}

return super.onintercepttouchevent (EV);
}
}

/**
* Rounded Corner ListView sample
* @Description: Rounded corner ListView Sample
* @FileName: Cornerlistview.java
*/
public class Cornerlistview extends ListView {
Public Cornerlistview {
Super (context);
}

Public Cornerlistview (context context, AttributeSet attrs, int defstyle) {
Super (context, attrs, Defstyle);
}

Public Cornerlistview (context context, AttributeSet Attrs) {
Super (context, attrs);
}

@Override
public boolean onintercepttouchevent (Motionevent ev) {
Switch (ev.getaction ()) {
Case Motionevent.action_down:
int x = (int) ev.getx ();
int y = (int) ev.gety ();
int itemnum = pointtoposition (x, y);

if (Itemnum = = adapterview.invalid_position)
Break
else{
if (itemnum==0) {
if (itemnum== (Getadapter (). GetCount ()-1)) {
Setselector (R.drawable.app_list_corner_round);
}else{
Setselector (R.drawable.app_list_corner_round_top);
}
}else if (itemnum== (Getadapter (). GetCount ()-1))
Setselector (R.drawable.app_list_corner_round_bottom);
else{
Setselector (R.drawable.app_list_corner_shape);
}
}

Break
Case MOTIONEVENT.ACTION_UP:
Break
}

return super.onintercepttouchevent (EV);
}
}

Among them, App_list_corner_round
