how to transfer photos from android to android

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

Android development, in different modules (such as activity) will often have a variety of data need to communicate with each other, commonly used in five ways of delivery. They have their own pros and cons and have their own application scenarios. Here are a few separate sections:1. Intent object passing simple dataThe extra portion of the intent can store the data that is passed, and can transfer some unde

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

Name; } Public voidSetName (String name) { This. name=name; } PublicUser (String name,intAge ) { This. name=name; This. age=Age ; } @Override Public intdescribecontents () {return0; } @Override Public voidWritetoparcel (Parcel dest,inti) {dest.writestring (GetName ()); Dest.writeint (Getage ()); } Public Static FinalCreatorNewCreator() {@Override PublicUser Createfromparcel (Pa

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

create a message Queue for the main thread. In this strand thread does not establish a message Queue. Therefore, the Mylooper value is null, and mainlooper points to the looper of the mainline thread. Then, execute to:Mhandler = new MyHandler (mainlooper);This mhandler belongs to the main thread.Mhandler.sendmessage (m);The M message is deposited into the message queue of the main thread. Mainlooper sees a message in the message queue and processes it, and the main thread executes to Mhandler's

Event transfer between android controls Public boolean dispatchTouchEvent (MotionEvent ev ){} For event distribution, all events in Android must be distributed through this method, and then decide whether to consume the current event or continue distributing it to the child Control for processing. If the return value is true, the distribution is not resumed and

Android network programming LAN transfer files:First, create a socket management class, which is the core class for transferring files, primarily for sending files and receiving filesThe specific code is as follows:1 PackageCom.jiao.filesend;2 3 ImportJava.io.BufferedReader;4 ImportJava.io.BufferedWriter;5 ImportJava.io.FileInputStream;6 ImportJava.io.FileOutputStream;7 ImportJava.io.InputStream;8 ImportJa

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
