7. Override the onTouchEvent () method.In this method, we mainly deal with dragging and dropping.Drag: the image of the selected item slides with the finger; put down is to exchange data when the drag ends.The overall structure of the method is as foll
Sometimes we need to make a custom radio list, but will encounter some problems, such as multi-choice, false selection problem, so look for information on the Internet, organize a demo out, paste the code:The contents of each row in the listUse a list of pagespublic class Mainactivity extends Activity {private ListView listview;private listviewadapter adapter;private string[] Be ans = new string[] {"1", "2"

Create a Material Design-style Android app-create a list and a card,
All my articles first published on my blog, welcome to attention, address: http://blog.isming.me
The last time I talked about using theme, applying the Material Design style, and card layout is also an important part of Material Design. I will write it today.Introduction
Create a complex List
The android list stops scrolling and loads images. This is a common method,
In the itemView of the Adapter, It is troublesome to judge whether the list is rolling. Coupling may be serious.
So I have considered whether it is possible to check the rolling status of the list in itemView and listen to the stopped status to
Write the following code in the activity:Final listThe ListView is to bind data to it by adapter, the simplest adapter is arrayadapter, and its corresponding data is a list of strings. Which Android. R.layout.simple_expandable_list_item_1 is a default display style provided by the system itself.Android Learning Note: ListView Simple and practical--Display text list
Program execution needs to read to security-sensitive items that must be declared in Androidmanifest.xml for the relevant permission request, the complete list is as follows:
Android.permission.ACCESS_CHECKIN_PROPERTIESAllow read-write access to the "Properties" table in the Checkin database, change the value can be modified upload.

GitHub Link: https://github.com/licaomeng/Android-PullToRefresh-SwipeMenuListView-SamplePulltorefresh is a very perfect drop-down refreshed open source project, Swipemenulistview is a left-swipe ListView in which item implementation can delete features of an open source project. I am here to integrate two sets of open source projects to form a set, similar to the mobile phone QQ, while supporting the drop-down refresh and swipe to the left of the
Multi-level lists are used in many areas of development. Android can use expandablelistview for good implementation. The following describes the implementation of mobile QQ.
The multilevel list uses expandablelistview and customizes the adapter;
Main. xml
Member_listview.xml
Member_childitem.xml
Exlistview. Java
public class ExListView extends Activity {private static final String G_TEXT = "g_text";
The previous Code has constructed an android source code library locally. Let's take a look at how the source code library is constructed.
All of this is based on the construction tool named repo. Go back to the initial command $ curl http://android.git.kernel.org/repo> ~ /Bin/RepoThis command downloads a script named repo from the website. It is actually a Python code segment. It is a bit interesting to look at it carefully. It is actually a small p
