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
                );

应用程序具有 READ_CONTACTS 和 WRITE_CONTACTS 权限。然而，查询返回异常。

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")));
            }

这里的名称、_id、数字是 simcard 表中的列名称

我明白了，

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，for(...){...}，你知道

我刚刚实现了一小段代码，用于显示 SIM 卡中的联系人列表。希望它可以帮助你

private void displaySIMContacts() {
    try {
        String simPhoneId = null;
        String simPhoneNum = null;
        String simPhoneName = null;

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

        while(simCursor.moveToNext()) {
            simPhoneId = simCursor.getString(simCursor.getColumnIndex("_id"));
            simPhoneNum = simCursor.getString(simCursor.getColumnIndex("name"));
            simPhoneName = simCursor.getString(simCursor.getColumnIndex("number"));
            Log.v("!!!", " id = " + simPhoneId + " - name = " + simPhoneName
                + " - number = " +simPhoneNum);
        }
    }
    catch (Exception e) {
       e.printStackTrace();
    }
}
