There are many features in android that can be used to apply any changes and settings to images. In this way, you can affect the photos, adjust the brightness and brightness, lighten or darken the image. These features are available in Android systems. To use these attractive and user-friendly features, we suggest that you follow this educational article and follow the tips mentioned in this article so that you can also use this attractive feature in Setting up Android systems.
To apply different changes and custom settings for images in Android systems, you can use the group Bitmaps. However, it should be noted that the Android procedures of these groups apply different types of settings, changes, and effects to images and introduce what they do.
The group of Bitmaps can be found under android.graphics.bitmaps. There are many ways to use settings from android.graphics.bitmap, and effects to images on Android systems. We choose how to create an imageview of the bitmap image. Like the following:
1- First, we must call the getBitmap () method from the BitmapDrawable group to finally create the bitmap. Like the following:
2- Images are two-point or two-dimensional matrices, so we can take the pixels from the bitmap and continue the process. Like the following:
To create an Android application, you will use the Eclipse IDE and name it as ImageEffects under the com.example package. Name the imageeffects. When creating this app, make sure the Target SDK and Compile With are in the latest version of the Android SDK to use higher API levels.
In addition to applying changes and settings and assigning effects to images, we can use settings to finally change the image display model. In this case, if we do not want a picture to be displayed suddenly and appear animated after other images, we can use this feature of Android systems.
This feature of the Android system that is used to display images in animation is called ImageSwitcher.
3- To apply settings so that the images are displayed one after the other, and an image does not appear suddenly, we must first define the XML component of the ImageSwitcher feature of the Android system. Like the following:
Its syntax is given below:
After inserting the above code, we create an example of the ImageSwithcer feature in the Java file and get a reference of the XML component. Like the following:
4- In the next step, we must apply settings to run the ViewFactory interface. Like the following:
5- After the above steps, we must add Animation to ImageSwithcer.
6- To do this, define an object from the Animation group through the AnimationUtilities group using the loadAnimation static call method. Like the following:
Note that setInAnimaton is used to adjust how the animation appears on the screen; however, setOutAnimation does the exact opposite of setInAnimaton.
loadAnimation () also creates an object for the animations.
7- In addition to the methods listed, other methods can be used in ImageSwitcher that are as follows:
- SetImageDrawable method:
Used to set an image with ImageSwithcer. The image is also transferred to the bitmap form.
- SetImageResource method:
Used to set an image with ImageSwithcer. The image is also transferred to the id form.
- SetImageURI method:
Used to set an image with ImageSwithcer. The image is transferred to the URI form.
- ImageSwitcher method:
Used to restore an image switcher object that has been configured with several features.
- OnInitializeAccessibilityEvent method:
Used to initialize an AccessibilityEvent.
- OnInitializeAccessibilityNodeInfo method:
Used to initialize an AccessibilityNodeInfo.
Below we want to give you an example to make it easier to understand the effects of image switcher on the bitmap.
1- In this part of the tutorial, we should use the Eclipse IDE to create an example.
2- The program was created with the name ImageSwitcher in the package com.example.imageswitcher. Name it.
Be sure to note that the Target SDK and Compile With are in the latest version of the Android SDK.
3- We need to change the src / MainActivity.java file to add other code.
4- We will also change the res/layout / activity_main file to add XML components. Like the following:
5- After making the necessary changes, we must run the created program.
6- After applying different types of changes to the program, the final codes and contents of the project will be as follows.
7- The contents of the AndroidManifest.xml file are as follows:
8- Now, we need to run the Image Switcher program.
9- To run the program created through the eclipse, we must run one of the project activities files.
10- After doing this, the program will be installed on AVD, and the Emulator page will be displayed.
11- In this case, two buttons will be displayed on the screen that if we select the top button to the right, a button will appear from the right and move to the left.
Suppose you follow all the steps in this article carefully. In that case, you can easily apply settings that change the image effect or use the image switcher feature to make the images appear animated.About our Android and iOS app development services
