Code sharing of square rounded corner listview in android Development

First look:

First, you have to write a class named CornerListView.

[Java]

Copy codeThe Code is as follows :/**
* Rounded ListView example
* @ Description: rounded ListView example
* @ FileName: CornerListView. java
*/
Public class CornerListView extends ListView {
Public CornerListView (Context context ){
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 );
}
}

/**

Public class CornerListView extends ListView {
Public CornerListView (Context context ){
Super (context );
}

Public CornerListView (Context context, AttributeSet attrs, int 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 )){

}
} Else if (itemnum = (getAdapter (). getCount ()-1 ))

Else {
SetSelector (R. drawable. app_list_corner_shape );
}
}

Break;
Case MotionEvent. ACTION_UP:
Break;
}

Return super. onInterceptTouchEvent (ev );
}
}
