" are used to specify the start and end positions of the match, because we only intend to replace the number in "BIT_MASK_0, therefore, only the matching area is set to a number during search.Because we need to replace the numbers of different rows with different values, we need to use an expression to calculate the value after replacement. When the replacement string of the ": s" command starts with "/=", it indicates that the result calculated using an expression is replaced. The expression he

ACTION_UP event, if the returned value in onTouchEvent is false, onTouchEvent only calls ACTION_DOWN instead of ACTION_UP. 1. Create two classes LLayout. The LView is as follows: Copy codeThe Code is as follows: public class LLayout extends FrameLayout { // ViewGroup @ Override Public boolean onInterceptTouchEvent (MotionEvent ev ){ Log. I ("LTAG", "LLayout onInterceptTouchEvent "); Log. I ("LTAG", "LLayout onInterceptTouchEvent default return" + sup

Create a simple canvas for Android multimedia development and learning A simple canvas can be drawn, selected, and saved. Of course, this tool is commonly used in communication software, such as QQ and feiqiu. Among them, we must listen to the touch events of the fingers. The touch events of the fingers are divided into three types: Press, lift, and move. Usually we only need to press the link, and then the entire finger Sliding Process. Then draw different straight lines during finger sliding.

'Let's create another Java module anotationVisible, is two annotation classes:@Target (Elementtype.type) @Retention (retentionpolicy.class) public @interface lactivity {}　　@Target (Elementtype.field) @Retention (retentionpolicy.runtime) public @interface lview { int value () default 0;}Then our main project introduced these two module can be used under our main project with this annotation, we make project will be in the project directory under BU

, Ontouch continues to invoke the Action_up event. If the return value in Ontouchevent is false, then ontouchevent will only invoke Action_down without invoking action_up. 1, the new two class Llayout, LView as follows Copy Code code as follows: public class Llayout extends Framelayout { ViewGroup @Override public boolean onintercepttouchevent (Motionevent ev) { LOG.I ("Ltag", "Llayout onintercepttouchevent"); LOG.I ("Ltag", "Llayout

In the development of the project, it is possible that some of the widgets brought by the system do not meet our needs, then we need to customize the view. By looking at common widgets like Button,textview,edittext in the system, they all inherit from view, so we naturally need to inherit view when inheriting custom view.1, first create a new class LView inherited from view Copy Code code as follows: public class

As the name suggests, searchview is a search view, which is similar to the automatically matched input box described earlier. However, he has his own listener and can get the user input result in real time. For the searchview control, I strongly recommend you place it on the actionbar to highlight the search function. However, the actionbar knowledge may be involved here, so here we will show you what this control is. Layout File Mainactivity. Java Package COM. kale. searchview; import android.
