![]() ![]() Step 12) Once these 3 variables are created, what we are going to do is inside our onCreate method, we are going to cast all these four variables. We are going to create three variables for our added text and one variable for our button. java file here and in here we can define 3 added text variables, because we have created in our design added text. Step 11) Now once this method is created, we can go to our main activity. So if this result is equal to -1 then we are going to return false, else we are going to return true. And then we can return this, if we can check if this value is minus one. Therefore we can define long and then result is equal to result because this insert returns the result as minus one or the inserted value. So what we can do is, this insert method, you can control and click this method and you can see here incase of error this method returns -1 and if successful this method returns row value. Step 10) Now how can we know that the values are really inserted into the table or not, okay. Step 9) Now once this is done we can just insert our data using this db instance, db.insert and this takes 3 arguments, first is the table name so our table name is this variable, second is null and third is our content value which we have created. And this will correspond to the value, surname and the marks value. In the same way, we will do the same for column 3 or the surname column and the marks column, right. This is the value we are going to pass here, okay. So column 2, the value which we’re going to pass. Step 8) Now we are going to take this content value instance and we’re going to put some data into the column,and it takes two arguments, first is the column name in which you want to insert the data and second is the value itself, so our first column name for name was column two. Step 7) Now the second thing which we need here is the instance of a class called content value and just press alt+enter to import all the classes Okay so, now its time to remove this line and you can paste the same line here because we’re are going to use this sqlite database instance in our insert data method so just paste it. Step 6) Now what we’re going to do is, first of all we’re going to create the instance of sqlite database, but last tutorial we have added in the constructor of this database helper this extra line so that we can see the database created. Now go to class name was database helper class and create a new method to insert data, add three arguments for this method, first is name, second is for surname and third is for marks right. Step 5) Now what we’re going to do is, while creating the database in the previous tutorial we created a class named database helper class for handling our database. Step 4) Now what we’re going to do is, we’re going to take a button and we’re going to change the text to 'Add Data' and also change the ID to button ad. So it’ll increment automatically when you insert some data inside your table, so we don’t need to add this ID specifically. ![]() Step 3) Now you maybe thinking that we have four columns in our table, first is ID, second is the name, third is surname an fourth is marks, but we have taken only three, you know three variables here. If you want you can change the ID names of these text views and added texts also. So first is the name, the second is surname and third is marks. Step 2) Now we are going to change the last text labels as the column names of our table.

In a blank activity we are going to drag and drop some text views here and some added texts here. Step 1) First of all go to your activity.xml file and go to the design tab there. Please follow the below steps in order insert some data in the table inside that SQlite Databse: In this tutorial, we will learn how to insert data into SQLite database in Android with example: How to Insert data into SQLite database in Android? Any data stored in SQLite database can easily accessible from Android Device Monitor without establishing any kind of connections for it such as JDBC. ![]() Android SQLite is the most preferred method of storing data in any android applications.Īndroid SQLite is a relational database, therefore, It supports all types of relational database features.
