As we all know, the data in the ListView is adapter adapted to the screen, so to implement the contents of each item in the ListView needs to manipulate the code in the adapter:We will refactor the following two methods when using different layouts: Getitemviewtype and Getviewtypecount.public class Myadapter extends Baseadapter {arraylistCreate a different viewholder by calling the type returned to determin

Why do I need to add channel information to my application?The launch of Android apps has to face a variety of markets, which we call channels. Sometimes, we need to know which channel the application is downloaded from. For example, we may need to count which markets bring a larger number of users. For example, we may have some profit needs and specific channels to divide. These are all statistical channels of information. How do you usually add cha

Recently, when a project in the team develops an APP, A WebView interface is used for display instead of a native control. One problem encountered during the development of this interface is that the fragmentation of Android causes many screen resolutions. Screens with different resolutions are compatible with the size of controls in the WebView of this interface. Because the size of

So so:if (condition 1) { image.setbackground (r.id.xxx1); Else if (condition 2) { image.setbackground (r.id.xxx2); As a matter of fact. If you have more states, you should create a new XML under the Drawable folder:level-listxmlns:android= "Http://schemas.android.com/apk/res/android"> ItemAndroid:maxlevel= "4"android:drawable= "@drawable/stat_sys_battery_0" /> ItemAndroid:maxlevel= "+"android:drawable= "@drawable/stat_sys_batt

After 4.0, a new Android project will automatically generate drawable,drawalbe-ldpi,drawable-mdpi,drawable-hdpi,drawable-xhdpi,drawable-xxhdpi six folders, In addition to Drawable, the other 5 folders correspond to four levels of Density:120dip (low), 160dip (Medium), 240dip (High), 320dip (Xhigh), 480dip (drawable-xxhdpi). The current mainstream approach is to put the picture file in the Drawable-hdpi folder, and the image-related XML file (such as b

The length of Android is: DP (or dip device independent pixels) an abstract unit based on screen density. On a monitor that is 160 dots per inch. 1dp=1px.Different devices have different display effects. This is related to device hardware. Use unit DP;SP (scaled Pixels) when layout is used primarily for font display, a pixel independent of the scale, similar to DP. However, it is possible to scale based on

Reading image resources from different locations (drawable, asset, SDCard) in Android Method 1: You have saved the image to the drawable directory and obtained the Drawable or Bitmap by using the image id. This method is most commonly used. (If you only know the image name, you can also obtain the image id through the image name) (1) Obtain Drawable by image id Drawable drawable = getResource (). getDrawabl

When developing a project, we encountered such a problem. The logon interface was implemented using the android native UI. After successful login, we will jump to the webview to load sencha touch data, however, when loading data from the webview to the backend, we found that the session at this time is different from the session at login, so we could not get the data. For this reason, Google has found a met
