Xadhiga XML

Extensible Markup Language (XML) is a widely used format in the Android app development process. Its advantages are that it is platform independent and user friendly. This article will explain the basics of XML and how it can be used to create a simple XML-Zeichenkette. In the first section we will explain the XML-Format and how it is used in Android apps.

XML documents are tree structures. Each document is composed of a root element and many child elements. The XML declaration defines the XML version. XML documents can contain multiple root elements and many child elements. Tusaale ahaan, a “title” element can contain multiple strings. If a variable has multiple values, a string definition can be used to store them.

To read the data from an XML-Zeichenketten, you should use the new method called aktiendataXmlString. Marka hore, you need to read the XML-String from the web server. Xiga, you should create a String-Array containing the relevant financial information. This object will be passed to the onPostExecute method automatically.

Lifecycle-Methode

When programming an Android application, you must understand the concept of the Lifecycle-Methode, which can be described as the ‘lifecycle’ of an application. In contrast to the C-based programming languages, which have a single lifecycle, Android applications have three lifecycles. Each one has its own characteristics, but they all work in similar ways. Guud ahaan, Android app programming follows the following lifecycle:

Marka hore, activities are the foundation of any Android app. Every screen is an activity, which means it must implement every lifecycle method to be effective. Activities should have a method called onCreate(), as this method is required to render content on the screen. The second method, onDestroy(), is called immediately before the activity is destroyed. There are various reasons why Android will destroy an activity.

OnPause() is a useful method to implement in an Android app. Marka hawshu istaagto, the system calls the onPause() habka. This method can be used to react to an activity being paused. Waxay kaloo waxtar u leedahay in lala macaamilo isticmaaleyaasha markii hawlo la joojiyo. Si kastaba ha ahaatee, Waa inaad ogaataa in qofkaas da 'yartaas ah() Waa in la yeeraa ka hor intaadan wicin Onreememe().

Dib-u-dhigid

Markaad dib u eegto barnaamijkaaga Android, Waxaad u baahan doontaa inaad ogaato sida loo galo aaladda dib-u-dhiska. Waxaad ka heli kartaa daaqadda qalabka xaga midig, ama xulashada aragtida > Windows Tool> Bax. Waxay leedahay icon dembain, waxaana lagu heli karaa adigoo gujinaya badhanka dib-u-eega ee daaqadda daaqadda. Daaqadda Debug wuxuu muujinayaa nidaamka hada jira ee Android iyo dhammaan noocyadeeda kala duwan. Adeegsiga badhanka Deynta ayaa kuu oggolaanaya inaad hubiso wax fariimo qalad ah oo lagu tuuro barnaamijkaaga.

Mar haddii daaqadda dib-u-dabka ay furan tahay, dhagsii “Xargaha” tab ka dibna xulashada dushiisa. Daaqadda Debug ayaa tusi doonta xargaha xirmada ee dunta kasta, oo waad baari kartaa qiimayaasha dunta kasta. Waxa kale oo aad gujin kartaa qeybta shaqsiyaadka ee ku jira xalka si aad u furto koodhka isha. Waxaa jira dhowr siyaabood oo lagu habeeyo xargaha qaabkan lagu muujiyey daaqadda Debugger. Waad ka dhoofin kartaa xirmooyinka xirmooyinka iyo sidoo kale aad u habayn karto soo bandhigiddooda adoo akhrinaya hagaha daaqadaha 'Debugger daaqadda'.

Hadaad haysatid pc kiniin ah ama laptop, Waxaad u isticmaali kartaa muuqaalka 'USB Regging' ee qalabkaaga Android. Si loo suuro galiyo habka loo yaqaan 'USB Debid', Tag xulashooyinka horumarinta ka dibna dooro “Qaabka Debinta.” Markaad karti u yeelatid USB dib-u-dhigidda, Si fudud ayaad u mari kartaa xulashooyinka horumarinta horumarsan sida u suurtagelinaya USB-ga. Si loo isticmaalo USB Debid, Hubso inaad soo celiso dhammaan xogta muhiimka ah ka hor intaadan sii wadin.
