Let’s say you are creating some kind of a selfie app, you may be interested in launching your camera using a much more modern way. This tutorial presents to you the solutions which you can use to launch the camera.

(a). Use CameraVideoButton

Instagram like animated button for taking photo or recording video.

This is just a dummy view. All recording or taking picture operation is up to you.

Step 1: Install it

The first step is to install the camera video button. Register jitpack in your project-level build.gradle as follows:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Then under the dependencies closure in your app level build.gradle add the implementation statement:

 implementation 'com.github.iammert:CameraVideoButton:0.2'

Step 2: Add to Layout

The next step is to add the camera video button to your xml layout:

<com.iammert.library.cameravideobuttonlib.CameraVideoButton
    android:id="@+id/videoRecordButton"
    android:layout_width="120dp"
    android:layout_height="120dp"
    app:cvb_recording_color="#D438A2"/>

Step 3: Write Code

First reference the CameraVideoButton whether it is by findViewById, data binding, kotlin synthetics or view binding.

Then you can customize its properties:

videoRecordButton.setVideoDuration(10000)
videoRecordButton.enableVideoRecording(true)
videoRecordButton.enablePhotoTaking(true)

Then you can now observer different events:

videoRecordButton.actionListener = object : CameraVideoButton.ActionListener{
    override fun onStartRecord() {
        Log.v("TEST", "Start recording video")
    }

    override fun onEndRecord() {
        Log.v("TEST", "Stop recording video")
    }

    override fun onDurationTooShortError() {
        Log.v("TEST", "Toast or notify user")
    }

    override fun onSingleTap() {
        Log.v("TEST", "Take photo here")
    }
}

Example

Let’s look at a simple example using the CameraVideoButton.

  1. First imstall the library as discussed earlier.

  2. Then add the camera videobutton to the xml layout:

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity"
    android:background="#232323">

    <com.iammert.library.cameravideobuttonlib.CameraVideoButton
        android:id="@+id/button"
        android:layout_width="120dp"
        android:layout_height="120dp"
        android:layout_centerInParent="true"
        android:layout_marginBottom="16dp"
        android:layout_alignParentBottom="true"
        app:cvb_recording_color="#D438A2"/>

</RelativeLayout>

3.Lastly write your kotlin code:

MainActivity.kt

package com.iammert.library.cameravideobutton

import android.support.v7.app.AppCompatActivity
import android.os.Bundle
import android.os.Handler
import android.util.Log
import com.iammert.library.cameravideobuttonlib.CameraVideoButton

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val videoRecordButton = findViewById<CameraVideoButton>(R.id.button)
        videoRecordButton.setVideoDuration(10000)
        videoRecordButton.actionListener = object : CameraVideoButton.ActionListener {
            override fun onCancelled() {
                Log.v("TEST", "onCancelled")
            }

            override fun onStartRecord() {
                Log.v("TEST", "onStartRecord")
            }

            override fun onEndRecord() {
                Log.v("TEST", "onEndRecord")
            }

            override fun onDurationTooShortError() {
                Log.v("TEST", "onDurationTooShortError")
            }

            override fun onSingleTap() {
                Log.v("TEST", "onSingleTap")
            }

        }

        Handler().postDelayed(Runnable {
            videoRecordButton.cancelRecording()
        }, 5000)
    }
}

That’s it. You can find the code here.
