How to Create New ImageView Dynamically on Button Click in Android?
In this article, we are going to implement a very important feature related to ImageView. Here we are going to add ImageView dynamically. We will be just changing the background color. Whenever we click on a button a new ImageView will be created. So here we are going to learn how to implement that feature. A sample video is given below to get an idea about what we are going to do in this article. Note that we are going to implement this project using the Java language.
Step by Step Implementation
Step 1: Create a New Project
To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Java as the programming language.
Step 2: Working with the activity_main.xml file
Navigate to the app > res > layout > activity_main.xml and add the below code to that file. Below is the code for the activity_main.xml file.
Step 3: Working with the MainActivity.java file
Go to the MainActivity.java file and refer to the following code. Here we are creating an ImageView and a layout and will add the ImageView in the layout. This is how we are creating an ImageView
ImageView imageView=new ImageView(AddImageViw.this); // adding the image in ImageView imageView.setImageResource(R.mipmap.ic_launcher);
This is how we are adding the newly created image view in our layout.
LinearLayout.LayoutParams params=new LinearLayout.LayoutParams(width,height); params.setMargins(0,10,0,10); // setting the margin in the layout imageView.setLayoutParams(params); layout.addView(imageView); // adding the image in the layout
Below is the complete code for the MainActivity.java file. Comments are added inside the code to understand the code in more detail.
