本人实学Android
这是网上下的一个ListView圆角的示例。
假如我想把设置1 item、设置2 item、设置3 item间隔开来，当然四个角都是圆角
大侠们，该如何实现？？
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.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);
}
}
RoundCornerActivity.java
public class RoundCornerActivity extends Activity {
private CornerListView mListView = null;
ArrayList<HashMap<String, String>> map_list1 = null;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
getDataSource1();
// getDataSource2();
SimpleAdapter adapter1 = new SimpleAdapter(this, map_list1,
R.layout.simple_list_item_1, new String[] { "item" },
new int[] { R.id.item_title });
mListView = (CornerListView) findViewById(R.id.list1);
mListView.setAdapter(adapter1);
mListView.setOnItemClickListener(new OnItemListSelectedListener());
}
public ArrayList<HashMap<String, String>> getDataSource1() {
map_list1 = new ArrayList<HashMap<String, String>>();
HashMap<String, String> map1 = new HashMap<String, String>();
HashMap<String, String> map2 = new HashMap<String, String>();
HashMap<String, String> map3 = new HashMap<String, String>();
map1.put("item", "设置1");
map2.put("item", "设置2");
map3.put("item", "设置3");
map_list1.add(map1);
map_list1.add(map2);
map_list1.add(map3);
return map_list1;
}
class OnItemListSelectedListener implements OnItemClickListener {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
if (arg2 == 0) {
System.out.println("0");
}else{
System.out.println("1");
}
}
}
}
