In real-world applications, you need to display a string with a different color and font. Of course, it can be stitched together by different textview.

Implementation Code Adapter code Viewholder has three different la s, that is, the layout of each item in listview. Type_1... is three types. When different la s are used, getitemviewtype and getviewtype should not be small. Generally, they do not need to be overloaded by these two functions. Class runrankadapter extends baseadapter {arraylist Usage: Declare and define your own adapter, and set its adapt

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

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

How do I adapt to the various screen sizes of Android smartphones using Qt-developed Android apps?When it comes to screen sizes, from 2.8-inch to 8.9-inch phone screens, it's a little more painful for program apes.
