android imageview setimageresource in code with solution

Android is a popular operating system that is used by millions of people around the world. It is an open-source platform that allows developers to create a wide range of applications for mobile devices. One of the most common features that developers add to their apps is the ability to display images.

To display images in an Android application, developers can use the ImageView class. The ImageView class is a subclass of the View class and is used to display images on the screen. In this article, we will discuss how to use the setImageresource method to set an image in an ImageView using code in Android.

What is setImageresource method?

setImageresource is a method that is used to set the image resource for an ImageView. This method takes a resource ID as a parameter and sets the image to the ImageView associated with that ID. The resource ID can be the ID of an image in the drawable folder.

How to use setImageresource in code?

To use the setImageresource method in code, follow these steps:

Step 1: Declare an ImageView in XML layout

The first step in using setImageresource in code is to declare an ImageView in your XML layout file. Open your activity_main.xml file and add the following code:

This code creates an ImageView with an ID of imageView and sets its size to wrap content. It also sets the image source to an image in the drawable folder called image.png.

Step 2: Declare ImageView in MainActivity

The next step is to declare the ImageView in your MainActivity file. Add the following code inside the onCreate method:

ImageView imageView = (ImageView) findViewById(R.id.imageView);

This code creates an instance of the ImageView class and assigns it to the imageView variable.

Step 3: Set Image Resource using setImageresource method

To set the image resource using setImageresource method, add the following code:

imageView.setImageresource(R.drawable.new_image);

This code sets a new image resource to the ImageView using the setImageresource method. The resource ID used here is R.drawable.new_image, which is an image in the drawable folder called new_image.png.

Step 4: Final Code

The final code for MainActivity.java is as follows:

public class MainActivity extends AppCompatActivity {
ImageView imageView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

    
    imageView = (ImageView) findViewById(R.id.imageView);
    imageView.setImageresource(R.drawable.new_image);
}

}

Conclusion

In this article, we discussed how to use the setImageresource method to set an image in an ImageView using code in Android. We also discussed the steps involved in using this method in a practical scenario. By following the steps outlined in this article, you can easily set an image in an ImageView in your Android application.
