Passing ArrayList<String> between tabs

由 丶灬走出姿态 提交于 2019-11-30 19:12:35
问题 I'm not very clear about the Intent object and how to use it to pass data between Activities. In my application I have several tabs between which I want to pass ArrayList. Here is a sample code I plan to use, but I'm missing the part where the main activity catches the Intent and passes it to the new activity on start : 1. myTabs.java ==> This is where I think I need to add some code to pass the data between TabOne and TabTwo. For now it is just using the sample code of the TabActivity sample

Please guide me. 回答1: There is also the AppInventor to Java Bridge project at java

由 左心房为你撑大大i 提交于 2019-11-30 09:20:49
I have a fairly simple game that works perfectly on every version now up through 2.1, but with the new 2.2 (Froyo) release I am unable to create a socket. I am using the mina package for nio, and get this exception: W/System.err( 263): java.net.SocketException: Bad address family W/System.err( 263): at org.apache.harmony.luni.platform.OSNetworkSystem.connectStreamWithTimeoutSocketImpl(Native Method) W/System.err( 263): at org.apache.harmony.luni.platform.OSNetworkSystem.connect(OSNetworkSystem.java:115) W/System.err( 263): at org.apache.harmony.nio.internal.SocketChannelImpl.connect
