How to set a custom button text for ImagePicker in Kotlin Android

How to set a custom button text for ImagePicker in Kotlin Android.

Here is a step-by-step tutorial on how to set a custom button text for ImagePicker in Kotlin Android:

Step 1: Add the ImagePicker library to your project​

To use ImagePicker, you need to add the library to your project. Open your project's build.gradle file and add the following line in the dependencies block:

implementation 'com.github.dhaval2404:imagepicker-support:1.5'

Step 2: Create a layout file for the activity​

Create a layout file for the activity where you want to use the ImagePicker. Open the desired layout file and add the following code:

<Button
    android:id="@+id/buttonSelectImage"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Select Image"
    />

Step 3: Initialize ImagePicker in your activity​

Open the Kotlin file for the activity and import the necessary classes:

import com.github.dhaval2404.imagepicker.ImagePicker
import com.github.dhaval2404.imagepicker.util.FileUriUtils

Then, initialize ImagePicker in your activity's onCreate method:

val buttonSelectImage = findViewById<Button>(R.id.buttonSelectImage)
buttonSelectImage.setOnClickListener {
    ImagePicker.with(this)
        .galleryOnly()
        .compress(1024) // Optional, you can set the desired compression size
        .start()
}

Step 4: Handle the image selection result​

Override the onActivityResult method in your activity and handle the image selection result:

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)

    if (requestCode == ImagePicker.REQUEST_CODE && resultCode == Activity.RESULT_OK) {
        val uri = data?.data
        val filePath = FileUriUtils.getRealPath(this, uri) // Get the file path from the URI

        // Perform any necessary operations with the selected image
    }
}

Step 5: Customize the button text​

To set a custom button text for ImagePicker, you can use the setText method on the button:

val buttonSelectImage = findViewById<Button>(R.id.buttonSelectImage)
buttonSelectImage.setOnClickListener {
    ImagePicker.with(this)
        .galleryOnly()
        .compress(1024) // Optional, you can set the desired compression size
        .start()

    buttonSelectImage.text = "Select Another Image" // Set the custom button text
}

That's it! You have successfully set a custom button text for ImagePicker in Kotlin Android. You can now run your app and test the functionality.

Note: Make sure to handle the necessary permissions and add the necessary code to handle runtime permissions if required.
