如何从Android中的联系人姓名获取联系人号码

一个较短的版本;
你仍然需要这个权限(android.permission.READ_CONTACTS)

public String getPhoneNumber(String name,Context context) {
String ret = null;
String selection = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" like'%" + name +"%'";
String[] projection = new String[] { ContactsContract.CommonDataKinds.Phone.numbER};
cursor c = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,projection,SELEction,null,null);
if (c.moveToFirst()) {
    ret = c.getString(0);
}
c.close();
if(ret==null)
    ret = "Unsaved";
return ret;
}
