为了让我的标签保留先前在其中输入的信息(如在EditText中),我将片段存储在backstack中,并尝试在用户切换标签时从后台弹出它并返回到之前的标签之一。
但是' popBackStack()'方法似乎不起作用。这是我的代码段:
version: '2'
services:
orderer.example.com:
container_name: orderer.example.com
image: hyperledger/fabric-orderer:$IMAGE_TAG
environment:
- ORDERER_GENERAL_LOGLEVEL=INFO
- ORDERER_GENERAL_LISTENADDRESS=0.0.0.0
- ORDERER_GENERAL_GENESISMETHOD=file
- ORDERER_GENERAL_GENESISFILE=/var/hyperledger/orderer/orderer.genesis.block
- ORDERER_GENERAL_LOCALMSPID=OrdererMSP
- ORDERER_GENERAL_LOCALMSPDIR=/var/hyperledger/orderer/msp
# enabled TLS
- ORDERER_GENERAL_TLS_ENABLED=true
- ORDERER_GENERAL_TLS_PRIVATEKEY=/var/hyperledger/orderer/tls/server.key
- ORDERER_GENERAL_TLS_CERTIFICATE=/var/hyperledger/orderer/tls/server.crt
- ORDERER_GENERAL_TLS_ROOTCAS=[/var/hyperledger/orderer/tls/ca.crt]
working_dir: /opt/gopath/src/github.com/hyperledger/fabric
command: orderer
volumes:
- ../channel-artifacts/genesis.block:/var/hyperledger/orderer/orderer.genesis.block
- ../crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp:/var/hyperledger/orderer/msp
- ../crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/:/var/hyperledger/orderer/tls
- orderer.example.com:/var/hyperledger/production/orderer
ports:
- 7050:7050
我的代码出了什么问题?我放了' popBackStack()'方法在错误的地方?
请帮助!

在向堆栈添加和删除片段时,尝试使用TAG的其他方法。 然后由TAG弹出。它应该工作
