In Android, data transmission between images is mainly implemented through the putextra method of intent. The transmitted data structure is a map data (name/value pair, note that the difference is that the basic data type must be used. The following describes the implementation methods through instances.
This example describes how to transfer the data of image 1 to Image 2, after Image 2 calculates and proc
In development, we often use the activity, then since the use of activity, it is inevitable to pass data between the two activity. Here we first talk about the principle, look at the code and examples.Situation A: We need to start and pass data from Activity_1 to activity_2,activity_2 only to receive data from Activity_1, but not for other operations.Case B: We need to start activity_2 from Activity_1, and want Activity_2 to pass the data to Activity_1 when it is destroyed.First of all, let's sa

Android Touch event Transfer Mechanism
In the previous article, I mainly explained the Touch event transfer process in the Android source code. Now I want to use a demo and an instance to learn about the Touch event handling process in Andorid.In the Android system, the th
, if my computer IP address is 192.168.0.110, you only need to double-click the computer icon of 192.168.0.110. At this time, you can see the shared folder name of the computer.
10. The last step is to copy and paste the desired file, select the desired file, and copy and paste it to your mobile phone's local memory card!
Data line transmission is not very convenient because of the influence of lines and interfaces. In addition, the data line connection is used for a long time, which may easily

Kingsoft kubernetes comes with the wifi fast transfer function. When this function is enabled, port 1080 is opened on the mobile phone. You can access port 1080 in a pc browser in the same LAN and a webpage is obt

The following is an example of passing list
Intent.putstringarraylistextra (key, list);
The syntax for receiving list

Here is an example of using:
============= Send listarraylistStringlist.add ("string1");Stringlist.add ("string2");Stringlist.add ("String3");Intent Intent = new Intent ();Intent.setclass
In the previous chapter we review the creation of activity and the life cycle, which we mainly learn about activity jumps and data transfer between activity.First, activity jumps:The simple jump between activity is simply a matter of creating two activity and then using startactivity (intent) to jump and see the code:Intent uio=New Intent (thisactivityclass,activitybclass); startactivity (UiO);What is intent?Andr

Two applications between the value, in fact, the title is too water, the professional argument is "two process how to pass the value", what?! It's not professional enough, okay, you're kinky! "Interprocess communication" is actually more professional, this time you always satisfied! Incidentally, abbreviated to IPC:inter-process communication.

This article illustrates the method of data transfer between Android implementation activities. Share to everyone for your reference. The specific analysis is as follows:
First, explain the start and shutdown of activity:
1. StartActivity (Intent Intent); Start activityFinish (); End Current Activity2. Startactivityforresult (Intent Intent, int requestcode); Starts an activity with the specified request c
Android development, often in the Java code and the JNI layer passed between the array (byte[]), a typical application is the Java layer to send the data sent to the client stream to the JNI layer, by the JNI layer socket code sent out, of course, The JNI layer also needs to return the data stream received from the socket to the Java layer. I summarized briefly, from the Java layer to the JNI layer, from the JNI layer to the Java layer, there are 3 ki
In the development of Android UI, we often encounter this requirement:Two components that support sliding, such as the ListView nested multiple Listview,listview item is a Viewpager or gallary? or ScrollView nested ScrollView and so on.In general, you may also need to support several features such as:¤ Two-layer components can slide¤ Do not let two components slide at the same time, or let two components sliding simultaneously and can adjust themselve
For example, interface a passes value to interface b1. Interface a considerations:(1) Intent put different types of parameters with the same name parameter the last one will overwrite the previous parameter (one parameter name can only correspond to one parameter value, and multiple parameters will be overwritten by the last parameter)2. Interface B Considerations:(2) Intent get different types of parameters, only if interface a put the parameters of the type, B interface to get to the value, ot
