transfer files from android to android via wifi

In Android development, the activity between intent using bundle,fragment between and activityty through the setarguments using bundles, for some simple parameter transfer is relatively simple, and there are many ways, This is not introduced. Here is a description of complex parameter passing, such as passing set ArrayList, Object arraylistThe bundle is basically the same, whether it is the parameter passin

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

Mainactivity is as follows: Package cn. c; import android. OS. bundle; import android. app. activity; import android. view. menu; // The first test // The output result is as follows: // call onInterceptTouchEvent () in MyFrameLayout // onInterceptTouchEvent () in MyFrameLayout returns by default: false // call onTouchEvent () in the Custom Button // The onTouchE

1. Global objects are a more practical way to transmit data between activities. For example, there are four scopes in Java Web. The Four Scopes are Page, Request, Session, and Application, the Application domain can be used and accessed anywhere in the Application, unless the Web server stops. The Global Object in Android is very similar to the Application field in Java Web. As long as the Android Applicati

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

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

Passing data between ActivtyPrior to learning how to start an activity, in some cases not only need to start another activity, but also to get the results returned. And sometimes more often when you start another activity with some values.1. Define a intent and specify the activity that will be started for the intent2. Call Startactivityforresult (Intent intent,int Requestcode) to jump and Mark Requestcode3. Rewrite onactivityresult (int requestcode,int resultcode,intent data) to parse the retur

Intent mainly includes implicit intent and explicit intent. Explicit intent is usually used to start data between activities in the current application, while implicit intent is commonly used in some specific actions in the startup system, such as making phone calls or sending text messages, or cross-app Activity startup (for example, clicking the link address on QQ to start a browser Activity ).Explicit Intent: Call Intent. setComponent (), Intent. setClass (), Intent. the setClassName () metho

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
