A button that you can slide on or off

How to import into your project

Android Studio

use gradle.

Gradle dependency:

Add the below codes in the module gradle file, which module use this widget.

compile 'com.leaking.slideswitch:slideswitch:1.0.0'

Add the below codes in you project gradle file

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://dl.bintray.com/leaking/maven'
        }
    }
}

Eclipse

import it as a library project.

How to use it

you can define a slideswitch in xml like the following example

    <com.leaking.slideswitch.SlideSwitch
        android:layout_width="100dip"
        android:layout_height="120dip"
        slideswitch:isOpen="false"
        slideswitch:shape="circle"
        slideswitch:themeColor="#f200aa96" >
    </com.leaking.slideswitch.SlideSwitch>

you can initial the state(on or off) in jave code in this way

	bulletSwitch.setState(true);

and you can listen to the change of the slideswitch like this

    updateSwitch.setSlideListener(new SlideListener() {

            @Override
            public void open() {
                // Do something ,,,
            }

            @Override
            public void close() {
                // Do something ,,,
            }
        });

you even can forbid the widget to change its state(open or close) like this

    slide.setSlideable(false);
    slide.setSlideable(true);

What does it look like

slideswitch's Issues

The background doesn't show as expected when I set it to circle.

When you set RIM_SIZE larger, you will find it obviously.

The radius of the background rounded rectangle maybe not big enough.

I found this problem due to this code in onDraw method:

radius = backRect.height() / 2 - RIM_SIZE;

Maybe you should remove the RIM_SIZE.

Memory leak

OOM exception -> drag the slider one way, then back again. The app will crash. I can reproduce this 100%. Commenting out line 205 moveToDest(toRight) stops the OOM. However leaves the functionality undesirable as the thumb can be left in whatever position you left it in.

提个建议

在moveToDest方法里面判断手势回调时增加当前状态的判断，如果当前是open状态，则继续重复右滑就不在回调，反之亦然。

public void moveToDest(final boolean toRight) {
        final Handler handler = new Handler() {
            @Override
            public void handleMessage(Message msg) {
                if (msg.what == 1) {
                    listener.open();
                } else {
                    listener.close();
                }
            }
        };
        new Thread(new Runnable() {
            @Override
            public void run() {
                if (toRight) {
                    while (frontRect_left <= max_left) {
                        alpha = (int) (255 * (float) frontRect_left / (float) max_left);
                        invalidateView();
                        frontRect_left += 3;
                        try {
                            Thread.sleep(3);
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    }
                    alpha = 255;
                    frontRect_left = max_left;
                    if (!isOpen) {
                        isOpen = true;
                        if (listener != null)
                            handler.sendEmptyMessage(1);
                        frontRect_left_begin = max_left;
                    }
                } else {
                    while (frontRect_left >= min_left) {
                        alpha = (int) (255 * (float) frontRect_left / (float) max_left);
                        invalidateView();
                        frontRect_left -= 3;
                        try {
                            Thread.sleep(3);
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    }
                    alpha = 0;
                    frontRect_left = min_left;
                    if (isOpen) {
                        isOpen = false;
                        if (listener != null)
                            handler.sendEmptyMessage(0);
                        frontRect_left_begin = min_left;
                    }
                }
            }
        }).start();
    }

Animation stops inside ScrollView

Hi, thank you for sharing this widget, I really liked it.
I was using it and making some particular adaptations when I encountered an issue. If I use the widget inside a ScrollView, starting the move to any side and then moving down or up, the ScrollView intercepts the MotionEvent and the switch stops the animation in the middle.

I found a solution and I want to share with you. When ScrollView handle the event, its children Views triggers the MotionEvent ACTION_CANCEL. So I copied the code inside inside ACTION_UP (line 188) and added another case ACTION_CANCEL, like this:

       <rest of code> ...

            break;
        case MotionEvent.ACTION_MOVE:
            eventMovingY = (int) event.getY();
            diffY = eventMovingY - eventStartY;

            eventLastX = (int) event.getRawX();
            diffX = eventLastX - eventStartX;
            int tempX = diffX + frontRect_left_begin;
            tempX = (tempX > max_left ? max_left : tempX);
            tempX = (tempX < min_left ? min_left : tempX);
            if (tempX >= min_left && tempX <= max_left) {
                frontRect_left = tempX;
                alpha = (int) (255 * (float) tempX / (float) max_left);
                invalidateView();
            }

            break;
        case MotionEvent.ACTION_UP:
            moveToDest(isToRight(event));
            break;
        case MotionEvent.ACTION_CANCEL:
            moveToDest(isToRight(event));
            break;
        default:
            break;
    }

private boolean isToRight(MotionEvent event) {
    int wholeX = (int) (event.getRawX() - eventStartX);
    frontRect_left_begin = frontRect_left;
    boolean toRight;
    toRight = (frontRect_left_begin > max_left / 2 ? true : false);
    if (Math.abs(wholeX) < 3) {
        toRight = !toRight;
    }
    return toRight;
}

I'm sorry for my english and thank you again!

when i put slideSwitch in RelativeLayout,it can't show correctly

the problem is above in title

ic_launcher.png

how can i resolve this issue?

android:layout_height is no effect

SlideSwitch could not use android:layout_height control it's height

themeColor不起作用，一直为黑色
