Question

我试图在同一活动中要求2个运行时权限。第一个将按钮触发并询问READ_CONTACTS，如果允许则通过onActivityResult继续。另一个运行时权限将询问SEND_SMS，如果允许，将转到onRequestPermissionsResult。现在，据我所知，它是如何工作的 - 我做错了。 2运行时权限需要通过其中一个选项运行，我需要使用Switch Case或某些东西来构建一个处理2个权限的方法，这样它就不会崩溃。我需要知道如何处理这两个事件，所以我不会允许联系人权限，活动将尝试运行SMS方法。

这是我无法摆脱的onActivityResult覆盖。

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    try {
        if (requestCode == REQUEST_CODE_PICK_CONTACTS && resultCode == RESULT_OK) {
            Log.d(TAG, "Response: " + data.toString());
            uriContact = data.getData();

            retrieveContactNumber();
        }
    }
    catch (Exception e){
        e.getStackTrace();
        Toast.makeText(SmsActivity.this, "Hi, I Tried :P", Toast.LENGTH_SHORT).show();
    }
}



private void retrieveContactNumber() {

    Cursor cursorID = getContentResolver().query(uriContact, new String[]{ContactsContract.Contacts._ID}, null, null, null);

    if (cursorID.moveToFirst()) {

        contactID = cursorID.getString(cursorID.getColumnIndex(ContactsContract.Contacts._ID));
    }

    cursorID.close();

    Log.d(TAG, "Contact ID: " + contactID);


    Cursor cursorPhone = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
            new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER},

            ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ? AND " +
                    ContactsContract.CommonDataKinds.Phone.TYPE + " = " +
                    ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE,

            new String[]{contactID},
            null);

    if (cursorPhone.moveToFirst()) {
        contactNumber = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
    }

    cursorPhone.close();
    txtCbNum = (EditText) findViewById(R.id.txtNum);
    txtCbNum.setText(contactNumber, TextView.BufferType.EDITABLE);

    Log.d(TAG, "Contact Phone Number: " + contactNumber);
}


private void requestSmsPermission() {

    if (ContextCompat.checkSelfPermission(SmsActivity.this, Manifest.permission.SEND_SMS) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(SmsActivity.this,
                new String[]{Manifest.permission.SEND_SMS},
                PERMISSION_SEND_SMS);
    } else {
        contactNumber = txtCbNum.getText().toString();
        sendSms(contactNumber, dibur);
    }


}

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {

    if (requestCode == PERMISSION_SEND_SMS) {

        contactNumber = txtCbNum.getText().toString();

        sendSms(contactNumber, dibur);
    } else if (requestCode == MY_PERMISSIONS_REQUEST_READ_CONTACTS) {
        try {
            // need to insert the contact number retrieve here

        } catch (Exception e) {
            e.getStackTrace();
            Toast.makeText(SmsActivity.this, "Hi, I Tried :P", Toast.LENGTH_SHORT).show();
        }
    } else {
        Toast.makeText(SmsActivity.this, "Permission denied, Can't send SMS.", Toast.LENGTH_LONG).show();
    }

}


private void sendSms(String phoneNumber, String message) {
    try {
        SmsManager sms = SmsManager.getDefault();
        sms.sendTextMessage(phoneNumber, null, message, null, null);
        Toast.makeText(SmsActivity.this, "Sms sent successfully to " + contactNumber, Toast.LENGTH_SHORT).show();
    } catch (Exception e) {
        Toast.makeText(SmsActivity.this, "SMS failed, please try again." + contactNumber, Toast.LENGTH_LONG).show();
        e.printStackTrace();
    }
}

Answer 1

您可以通过作为第二个参数传递的整数来区分两个onRequestPermissionsResult()个调用。该值作为参数提供给ActivityCompat.requestPermissions(this, ..., RESULT_PERMS_RECORD_VIDEO);。

因此，例如，如果在一个地方你有：

...

（包含ActivityCompat.requestPermissions(this, ..., RESULT_PERMS_TAKE_PICTURE);的权限名称数组）

在另一个地方你有：

...

（可能是@Override public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { if (requestCode==RESULT_PERMS_TAKE_PICTURE) { // do something } else if (requestCode==RESULT_PERMS_RECORD_VIDEO) { // do something else } }）

的不同权限名称数组

然后你可以：

10:00, 23:00, 1:00, 9:00

同一活动中包含2个请求的运行时权限
