Start an new Activity Intent with a parameter Android example

Integer, Float, String, List passed as reference in JAVA example source code:

// List passed as reference JAVA
List<Integer>list = new ArrayList<Integer>();

public void fc (List<Integer>listRef){
listRef.add(7);
listRef.add(5);
}
fc(list); // 7, 5 


// String passed as reference JAVA
	public void mutate(AtomicReference<Object> ref) { ref.set("Goodbye"); }

		AtomicReference<Object> ref = new AtomicReference<Object>("Hello");
		mutate(ref);
		System.out.println(ref.get()); //Goodbye!
             String s = (String) ref.get();


// Integer passed as reference JAVA
	private static void mutate(AtomicReference<Object> ref) { ref.set(7); }

	//public static void main(String[] arg) {
		AtomicReference<Object> ref = new AtomicReference<Object>(5);
		mutate(ref);
		System.out.println(ref.get()); // 7
int n = (Integer) ref.get();


// Float passed as reference JAVA
	private static void mutate(AtomicReference<Object> ref) { ref.set(14.8f); }

	//public static void main(String[] arg) {
		AtomicReference<Object> ref = new AtomicReference<Object>(12.1f);
		mutate(ref);
		float f = (Float) ref.get();
		System.out.println(f); //14.8

create div with class with name e.g. circle


create in styleSheet.css class circle

html code

 <div class="circle" id="">3</div>

css code

.circle {
 border-radius: 50%;
    width: 50px;
    height: 50px;
    background: yellow;
    position: absolute;
    display: block;
    border: 6px solid blue;
    font-size: 50px;
    text-align: center;
}

Sqlite3 create database and table with load.bat file and fill data to table example.

1. Create folder for your project: my_sqlite_project


2. Open folder and create file load.bat and paste to load.bat this text and save to project folder:
   

   
   
   
   sqlite3 my_database.s3db < load_text.sql
   
   pause
   
   
   
   




3. Create load_text.sql file and paste this text and save to project folder:
   

   
   CREATE TABLE [android_metadata] (
   
   [locale] TEXT
   
   );
   
   
   
   
   
   
   
   
   
   CREATE TABLE [my_table] (
   
   [_id] int NULL,
   
   [word] VARCHAR(255)  NULL,
   
   [description] VARCHAR(255)  NULL
   
   
   
   
   
   
   
   
   
   .separator ";"
   
   .import text_file.txt my_table
   
   
   
   



4. Create text_file.txt and paste this text and save it as UTF-8:
   

   
   1;word1;my first word
   
   2;word2; my second word 
   
   

   
   



5. Download sqlite3.exe and put to project folder.


6. Run BAT file load.bat and read text instruction from console


7. If database created you can open and edit this with sqlite database explorer


8. Copy database to Asses Android project folder


9. If you want using this database in Android application on device, you have to copy this database to folder on device /data/data/com.MyPackage/databases/

Check if in drawable folder have two picture with same name and delete one.
For example:

image_1.jpg
image_1.png


Check the module build folder in Android Studio for two files with same names.

C:\Users\myFolder\AndroidStudioProjects\Project\yourModule\build\intermediates\res\merged\debug\drawable\


Converting to string: TypedValue{t=0x10/d=0xe a=-1}

    

        14 // error

        "18" // ok
