Android:如何使用SDK访问SIM联系人表？

Question

我正在尝试使用此查询来读取SIM卡上的联系人.

            cur = managedQuery(Uri.parse("content://icc/adn")
                ,null
                ,null
                ,null
                ,null
                );

该应用程序具有READ_CONTACTS和WRITE_CONTACTS权限.然而,查询返回一个异常.

怎么了？

Answer 1

我使用以下代码来获取simcard详细信息..它工作正常

Uri simUri = Uri.parse("content://icc/adn");
        Cursor cursorSim    = this.getContentResolver().query(simUri, null, null,null, null);

         while (cursorSim.moveToNext()) {           
             listName.          add(cursorSim.getString(cursorSim.getColumnIndex("name")));
             listContactId.     add(cursorSim.getString(cursorSim.getColumnIndex("_id")));      
             listMobileNo.      add(cursorSim.getString(cursorSim.getColumnIndex("number")));
            }

这里名称_id,number是simcard表中的列名

Answer 2

我得到了它，

String simUrl = "content://icc/adn";
Intent intent = new Intent();
            Log.d(TAG, "simUrl=" + simUrl);
            intent.setData(Uri.parse(simUrl));
            Uri uri = intent.getData();
            Cursor mCursor = context.getContentResolver().query(uri, null,
                    null, null, null);

然后，对于(...){...}，你知道
