You can use this library to quickly and easy customize your unlock.

Use this code on xml

 <cheekiat.slideview.SlideView
        android:id="@+id/slide_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:slideBackground="@drawable/orangesquarebutton"
        app:slideSrc="@drawable/slide_image"
        app:slideText="Slide to unlock"
        app:slideTextColor="#ffffff"
        app:slideTextSize="10dp" />

Answer 3

Android provides the Switch widget that is similar to slide to unlock. However, you will have to customize it a little, e.g. disable change on click.

Answer 4

First of all I'd like to thank @matthias for his answer. I have used the following seek bar with some customization:

 <SeekBar
        android:id="@+id/myseek"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:clickable="false"
        android:max="100"
        android:progressDrawable="@android:color/transparent"
        android:thumb="@drawable/ic_launcher" />

and in java code

sb.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {

            if (seekBar.getProgress() > 95) {

            } else {

                seekBar.setThumb(getResources().getDrawable(R.drawable.ic_launcher));
            }

        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {


        }

        @Override
        public void onProgressChanged(SeekBar seekBar, int progress,
                boolean fromUser) {
            if(progress>95){
                seekBar.setThumb(getResources().getDrawable(R.drawable.load_img1));
            }

        }
    });

I Hope below Ans is work,

    public class UnlockSliderView extends FrameLayout {
    @BindView(R2.id.tv_unlock_slider)
    TextView tvUnlockSlider;

    @BindView(R2.id.iv_circle_slide)
    ImageView ivCircleSlide;

    private View parentCircle;

    private float xOrigin = 0;
    private float xOriginCircle = 0;
    private boolean circleTouched = false;

    public UnlockSliderView(Context context) {
        super(context);
        init();
    }

    public UnlockSliderView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public UnlockSliderView(Context context, AttributeSet attr, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init();
    }

    private void init() {
        inflate(getContext(), R.layout.layout_unlock_slider_view, this);
        ButterKnife.bind(this);

        parentCircle = (View) ivCircleSlide.getParent();
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            eventActionDown(event);
        } else if (event.getAction() == MotionEvent.ACTION_MOVE) {
            eventActionMove(event);
        } else if (event.getAction() == MotionEvent.ACTION_UP) {
            unlockFinish();
        }
        return true;
    }

    private void eventActionDown(MotionEvent event) {
        if ((event.getX() >= ivCircleSlide.getX() && event.getX() <= ivCircleSlide.getX() + ivCircleSlide.getWidth())
                && (event.getY() >= ivCircleSlide.getY() && event.getY() <= ivCircleSlide.getY() + ivCircleSlide.getHeight())) {
            xOrigin = event.getX();
            xOriginCircle = ivCircleSlide.getX();
            circleTouched = true;
        } else {
            circleTouched = false;
        }
    }

    private void eventActionMove(MotionEvent event) {
        if (circleTouched) {
            float newXCircle = xOriginCircle + (event.getX() - xOrigin);
            newXCircle = (newXCircle < xOriginCircle) ? xOriginCircle : newXCircle;
            newXCircle = (newXCircle > parentCircle.getWidth() - ivCircleSlide.getWidth() - xOriginCircle) ? parentCircle.getWidth() - ivCircleSlide.getWidth() - xOriginCircle : newXCircle;
            float alpha = 1 - ((newXCircle - xOriginCircle) / (parentCircle.getWidth() - ivCircleSlide.getWidth() - (xOriginCircle * 2)));
            tvUnlockSlider.setAlpha(alpha);
            ivCircleSlide.setX(newXCircle);
            if (newXCircle == parentCircle.getWidth() - ivCircleSlide.getWidth() - xOriginCircle) {
                unlockFinish();
                if (mListener != null) mListener.onUnlock();
            }
        }
    }

    private void unlockFinish() {
        if (circleTouched) {
            ivCircleSlide.animate().x(xOriginCircle).setDuration(400).start();
            tvUnlockSlider.animate().alpha(1).setDuration(400).start();
            circleTouched = false;
        }
    }




   and the xml is,

  <?xml version="1.0" encoding="utf-8"?>
