Android中用Shape实现圆角和局部圆角等
如图，UI 妹妹想要此种效果，我与美美约定，我画不出来你就来 Help Me。她说你最棒你行的。我害羞的笑一笑。
其实确实简单，不就一个框加一个扇形圆么？
直接代码记录，需要的 Copy 。
OK了，截图能说明一切，更清晰！
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/white"
android:orientation="horizontal"
android:paddingBottom="5dp"
android:paddingTop="5dp" >
a_shanxing_yuan_selected_kuang.xml
android:color="#ff7521" />
android:bottomRightRadius="0dip"
android:topLeftRadius="0dip"
android:topRightRadius="0dip" />
a_shanxing_yuan_selected_shape.xml
android:bottomRightRadius="0dp"
android:topLeftRadius="0dp"
android:topRightRadius="0dp" />
-——————corners的值 与 size_size android:height值注意一下，就OK了，
然后就是嵌套啦，扇形与外框嵌套，再嵌套到条目里面。
由于这个项目维护了4-5年很老，所以用listview实现的很Low，关键是记录 shape。
补充一下选中与未选中 ：
final List
if (site_list != null) {
Log.e(TAG, " DJDetailTestSiteAdapter(this, site_list) ");
final DJDetailTestSiteAdapter djDetailTestSiteAdapter = new DJDetailTestSiteAdapter(this, site_list);

for (int i = 0; i < site_list.size(); i++) {
if (i == 0) {
site_list.get(i).isFocus = true;

关于自定义drawable圆角，代码中动态修改边线及填充色
在代码中根据需求动态的修改填充色及背景色
//tvBind是我的textview控件，将边线的颜色变成红色，边线宽度2dp
GradientDrawable drawable = (GradientDrawable) tvBind.getBackground();
drawable.setStroke(2, getResources().getColor(R.color.mall_red_text));
//改变drawable的背景填充色
drawable.setColor(getResources().getColor(R.color.mall_red_text));
