在我的 Android 应用程序（用 Java 编写）中，我有一个功能可以使用扫描的信息将联系人添加到用户的手机中。一旦用户授予应用程序编辑设备联系人的权限，该功能就会完美运行。但是，在授予权限后，用户需要再次按下“添加到联系人”按钮，因为该操作未执行，开始。就好像原始命令被抛出以征求用户执行该操作的权限。有什么办法可以在授予权限后立即添加联系人吗？第一次使用该应用程序的用户不会知道他们第一次添加联系人时需要在授予权限后第二次按下按钮。

这是“添加到联系人”方法的代码：

private void addToContact(View v) {
    //if the permission if off
    Ask.on(this)
            .forPermissions(Manifest.permission.WRITE_CONTACTS)
            .go();

    int phoneType = 1;
    int emailType = 1;

    // Prepare contact creation request
    //
    // Note: We use RawContacts because this data must be associated with a
    // particular account.
    // The system will aggregate this with any other data for this contact
    // and create a coresponding entry in the ContactsContract.Contacts provider for us.
    ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();

    ops.add(ContentProviderOperation
            .newInsert(ContactsContract.RawContacts.CONTENT_URI)
            .withValue(ContactsContract.RawContacts.ACCOUNT_TYPE, null)
            .withValue(ContactsContract.RawContacts.ACCOUNT_NAME, null)
            .build());
    ops.add(ContentProviderOperation
            .newInsert(ContactsContract.Data.CONTENT_URI)
            .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)
            .withValue(
                    ContactsContract.Data.MIMETYPE,
                    ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE)
            .withValue(
                    ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME,
                    mContactName).build());
    ops.add(ContentProviderOperation
            .newInsert(ContactsContract.Data.CONTENT_URI)
            .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)
            .withValue(
                    ContactsContract.Data.MIMETYPE,
                    ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE)
            .withValue(ContactsContract.CommonDataKinds.Phone.NUMBER,
                    mContactPhoneNumber)
            .withValue(ContactsContract.CommonDataKinds.Phone.TYPE,
                    phoneType).build());
    ops.add(ContentProviderOperation
            .newInsert(ContactsContract.Data.CONTENT_URI)
            .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)
            .withValue(
                    ContactsContract.Data.MIMETYPE,
                    ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE)
            .withValue(ContactsContract.CommonDataKinds.Email.DATA,
                    mContactEmail)
            .withValue(ContactsContract.CommonDataKinds.Email.TYPE,
                    emailType).build());
    ops.add(ContentProviderOperation
            .newInsert(ContactsContract.Data.CONTENT_URI)
            .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)
            .withValue(
                    ContactsContract.Data.MIMETYPE,
                    ContactsContract.CommonDataKinds.Organization.CONTENT_ITEM_TYPE)
            .withValue(
                    ContactsContract.CommonDataKinds.Organization.COMPANY,
                    mContactOrg)
            .withValue(ContactsContract.CommonDataKinds.Organization.TITLE,
                    mContactTitle)
            .withValue(ContactsContract.CommonDataKinds.Organization.TYPE,
                    1).build());
    ops.add(ContentProviderOperation
            .newInsert(ContactsContract.Data.CONTENT_URI)
            .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)
            .withValue(
                    ContactsContract.Data.MIMETYPE,
                    ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE)
            .withValue(
                    ContactsContract.CommonDataKinds.StructuredPostal.FORMATTED_ADDRESS,
                    mContactAddress).build());

    // Ask the Contact provider to create a new contact
    Log.i(TAG, "Selected account: " + ACCOUNT_TYPE + " (" + ACCOUNT_NAME
            + ")");
    Log.i(TAG, "Creating contact: " + mContactName);
    int duration = Toast.LENGTH_SHORT;
    Context ctx = getApplicationContext();
    try {
        getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
        Toast toast = Toast.makeText(ctx, "contact created  successfully",
                duration);
        toast.show();

    } catch (Exception e) {
        // Display warning

        Toast toast = Toast.makeText(ctx, "contact creation failed",
                duration);
        toast.show();

        // Log exception
        Log.e(TAG, "Exception encountered while inserting contact: " + e);
    }
}

这里是调用方法的地方：

mAddToContactButton.setOnClickListener(new Button.OnClickListener() {
        public void onClick(View v) {
            addToContact(v);
        }
    });
