android取得账户(邮件地址)

android账户取得方法：

方法1：可以使用AccountManager

先在AndroidManifest.xml中加入权限：

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

代码中取得账户的方法：

你可以用AccountManager.getAccountsorAccountManager.getAccountsByType来获取账户列表

Pattern emailPattern = Patterns.EMAIL_ADDRESS; // API level 8+Account[] accounts = AccountManager.get(context).getAccounts();for (Account account : accounts) {    if (emailPattern.matcher(account.name).matches()) {        String accountName = account.name;        String accountType = account.type;        System.out.println("name:" + accountName + "\n" + "type:" + accountType);    }}

如果登陆的google账户，取出来的类似：

name:xxx@gmail.com

type:com.google

方法2：使用ContactsContract.Profile（4.0以上才有）

先在AndroidManifest.xml中加入权限：

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

例子代码：

public class ExampleActivity extends Activity implements LoaderManager.LoaderCallbacks<Cursor> {    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        getLoaderManager().initLoader(0, null, this);    }    @Override    public Loader<Cursor> onCreateLoader(int id, Bundle arguments) {        return new CursorLoader(this,                // Retrieve data rows for the device user's 'profile' contact.                Uri.withAppendedPath(                        ContactsContract.Profile.CONTENT_URI,                        ContactsContract.Contacts.Data.CONTENT_DIRECTORY),                ProfileQuery.PROJECTION,                // Select only email addresses.                ContactsContract.Contacts.Data.MIMETYPE + " = ?",                new String[]{ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE},                // Show primary email addresses first. Note that there won't be                // a primary email address if the user hasn't specified one.                ContactsContract.Contacts.Data.IS_PRIMARY + " DESC");    }    @Override    public void onLoadFinished(Loader<Cursor> cursorLoader, Cursor cursor) {        List<String> emails = new ArrayList<String>();        cursor.moveToFirst();        while (!cursor.isAfterLast()) {            emails.add(cursor.getString(ProfileQuery.ADDRESS));            // Potentially filter on ProfileQuery.IS_PRIMARY            cursor.moveToNext();        }        ...    }    @Override    public void onLoaderReset(Loader<Cursor> cursorLoader) {    }    private interface ProfileQuery {        String[] PROJECTION = {                ContactsContract.CommonDataKinds.Email.ADDRESS,                ContactsContract.CommonDataKinds.Email.IS_PRIMARY,        };        int ADDRESS = 0;        int IS_PRIMARY = 1;    }}
