        if (cursor.getCount() >0) {
            while (cursor.moveToNext()) {
                String name = getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                output.append("Name: "+name+"\n");
            }
            textView1.setText(output);
        }
        cursor.close();
    }

我搜索了一下网页并尝试将权限放入活动注册但到目前为止没有运气。

愿任何人友好地建议，非常感谢你。

Answer 1

它应该是use-permission，而不是用户

Answer 2

这是我的区分大小写问题。下面的代码对我有用。

mvn install

Answer 3

替换

<user-permission android:name="android.permission.READ_CONTACTS" />

到

<uses-permission android:name="android.permission.READ_CONTACTS" />

它应该<uses ...而不是<user ..

试试这个.... :)
