废话不多说了,直接给大家贴代码了,具体代码如下所述:

/**
* 把一个view的对象转换成bitmap
*/
private bitmap getviewbitmap(mapview v) {
v.clearfocus();
v.setpressed(false);
//能画缓存就返回false
boolean willnotcache = v.willnotcachedrawing();
v.setwillnotcachedrawing(false);
int color = v.getdrawingcachebackgroundcolor();
v.setdrawingcachebackgroundcolor(0);
if (color != 0) {
v.destroydrawingcache();
}
v.builddrawingcache();
bitmap cachebitmap = null;
while(cachebitmap == null){

}
bitmap bitmap = bitmap.createbitmap(cachebitmap);
// restore the view
v.destroydrawingcache();

public void savemybitmap(string bitname,bitmap mbitmap){

//缩小
private class buttonnexitclicklistener implements view.onclicklistener {
