如何在android中滑动解锁按钮

Question

嗨，我想要一个可以用作 IOS 的“滑动解锁”按钮的按钮

简而言之，我想要一个没有点击效果但可以在拖动时从左向右滑动的按钮，并且在拖动完成时应该考虑点击。

如果可能，请给我建议任何示例代码。

谢谢！

Answer 1

首先，我要感谢@matthias 的回答。 我使用了以下搜索栏并进行了一些自定义：

 <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" />

并在java代码中

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));
            }

        }
    });

Answer 2

我从 Jignesh Ansodariya 发布的示例开始，但正如 Aerrow 指出的那样，用户可以单击 SeekBar 上的任意位置来解锁。 这使得它非常无法使用，因为拥有滑动按钮的重点是应该忽略意外点击。 我的解决方案是创建 SeekBar 的子类，如下所示：

public class SlideButton extends SeekBar {

    private Drawable thumb;
    private SlideButtonListener listener;

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

    @Override
    public void setThumb(Drawable thumb) {
        super.setThumb(thumb);
        this.thumb = thumb;
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            if (thumb.getBounds().contains((int) event.getX(), (int) event.getY())) {
                super.onTouchEvent(event);
            } else
                return false;
        } else if (event.getAction() == MotionEvent.ACTION_UP) {
            if (getProgress() > 70)
                handleSlide();

            setProgress(0);
        } else
            super.onTouchEvent(event);

        return true;
    }

    private void handleSlide() {
        listener.handleSlide();
    }

    public void setSlideButtonListener(SlideButtonListener listener) {
        this.listener = listener;
    }   
}

public interface SlideButtonListener {
    public void handleSlide();
}

XML：

        <package.SlideButton
            android:id="@+id/unlockButton"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:clickable="false"
            android:max="100"
            android:progressDrawable="@android:color/transparent"
            android:thumb="@drawable/button_lock" >
        </package.SlideButton>

最后是我的 Activity 中的代码：

    ((SlideButton) findViewById(R.id.unlockButton)).setSlideButtonListener(new SlideButtonListener() {  
        @Override
        public void handleSlide() {
            unlockScreen();
        }
    });

Answer 3

有一些很好的库可以为您解决问题。 如果使用库来执行此操作对您来说不是问题，请考虑尝试以下方法：

https://github.com/cortinico/slidetoact

快乐编码.. !! :)

Answer 4

Android 提供了类似于滑动解锁的Switch小部件。 但是，您必须对其进行一些自定义，例如禁用单击更改。

Answer 5

您可以使用此库快速轻松地自定义您的解锁。

https://github.com/cheekiat/SlideToUnlock

在 xml 上使用此代码

 <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 6

出于某种原因，我无法禁用触摸操作，因此仍然可能会意外点击
我想出了这个解决方案，它基本上不允许每个更改事件更改超过 10 个值的进度

int unlockLastSeekVal = 0;
// there are skips btwn changes, use value greater than 1
// 10 is great for seekbars with 100 values
int unlockSeekSensitivity = 10;
// final stage to "unlock"; 0.9 => 90%
Double unlockFinalStage = 0.9;
//...........
unlock.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
    public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
        if (fromUser){
            if (Math.abs(unlockLastSeekVal - progress) > unlockSeekSensitivity){
                // too much delta, revert to last value
                seekBar.setProgress(unlockLastSeekVal);
            }else{
                unlockLastSeekVal = progress;
            }
        }
    }

    public void onStartTrackingTouch(SeekBar seekBar) {
    }

    public void onStopTrackingTouch(SeekBar seekBar) {
        if (seekBar.getProgress() > seekBar.getMax() * unlockFinalStage){
            DoYourThing();
        }
        unlockLastSeekVal = 0;
        seekBar.setProgress(0);         
    }
});

Answer 7

从奥斯卡的回答开始（感谢您的贡献），我创建了一个简单的示例项目来管理滑动按钮（水平和垂直）： https : //github.com/rcaboni/AndroidSlideButton

对于屏幕截图： https : //raw.githubusercontent.com/rcaboni/AndroidSlideButton/master/screenshot.jpg

这是主要方法：

public boolean onTouchEvent(MotionEvent event) {
    if (!isEnabled()) {
        return false;
    }
    if (orientation == ORIENTATION_HORIZONTAL) {
        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            int x= (int) event.getX();
            int y= (int) event.getY();
            if (thumb.getBounds().contains((int) event.getX(), (int) event.getY())) {
                super.onTouchEvent(event);
            } else
                return false;
        } else if (event.getAction() == MotionEvent.ACTION_UP) {
            if (getProgress() > 70)
                handleSlide();

            setProgress(0);
        } else
            super.onTouchEvent(event);
    }else{
        int i=0;
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                if (event.getAction() == MotionEvent.ACTION_DOWN) {
                    int x= (int) event.getX();
                    int y= (int) event.getY();
                    if (!thumb.getBounds().contains((int) event.getY(), (int) event.getX())) {
                        return false;
                    }
                }
            case MotionEvent.ACTION_MOVE:
                i=getMax() - (int) (getMax() * event.getY() / getHeight());
                setProgress(100 - i);
                onSizeChanged(getWidth(), getHeight(), 0, 0);
                break;
            case MotionEvent.ACTION_UP:
                i=getMax() - (int) (getMax() * event.getY() / getHeight());
                if (i < 30) {
                    handleSlide();
                }
                setProgress(0);
                onSizeChanged(getWidth(), getHeight(), 0, 0);
                break;

            case MotionEvent.ACTION_CANCEL:
                break;
        }
    }
    return true;
}

垂直按钮的 XML：

<RelativeLayout
    android:layout_width="75dp"
    android:layout_height="130dp"
    android:background="@drawable/slide_background_green"
    android:id="@+id/lSlideButtonV"
    android:layout_below="@+id/lSlideButton"
    android:layout_marginTop="50dp">
    <TextView
        android:layout_width="20dp"
        android:layout_height="match_parent"
        android:text="SOS"
        android:id="@+id/tvSlideActionV"
        android:gravity="center|bottom"
        android:layout_alignParentRight="false"
        android:layout_alignParentEnd="false"
        android:layout_alignParentLeft="false"
        android:layout_alignParentStart="false"
        android:textSize="20dp"
        android:textColor="@android:color/white"
        android:layout_alignParentTop="false"
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="false"
        android:layout_marginBottom="15dp" />
    <it.aldea.android.widget.SlideButton
        android:id="@+id/unlockButtonV"
        android:layout_width="match_parent"
        android:layout_height="150dp"
        android:clickable="false"
        android:max="100"
        slideButton:orientation="vertical"
        android:progressDrawable="@android:color/transparent"
        android:thumb="@drawable/slide_track_red"
        android:indeterminate="false"
        android:layout_marginRight="5dp"
        android:layout_marginTop="20dp"
        android:layout_centerInParent="true"
        android:layout_marginBottom="10dp"
        android:thumbOffset="-2dp">
    </it.aldea.android.widget.SlideButton>

</RelativeLayout>

它不是一个真正完整的小部件，因为它是由两个视图（TextView 和 SlideButton）组成的一个布局，但它是一个简单的可配置解决方案，用于内部带有文本的滑动按钮。 我希望这对某人有用。

Answer 8

可能很晚了，但我为此创建了一个小型图书馆。 它允许您从 xml 滑动和自定义按钮的行为。 滑动按钮

基本上它涉及覆盖 onTouch() 事件并根据接收到的坐标进行更改。 之后，根据需要设置背景并自定义文本是一件简单的事情。

Answer 9

您可以重建正常的 SeekBar 来执行您想要的操作：

和：

• 起点 (20)
• 交叉线 (90)

• 并自动复位。

  seekBar.setOnSeekBarChangeListener( new SeekBar.OnSeekBarChangeListener() { Integer point = 0; Integer startPoint = 0; boolean started = true;

   @Override public void onProgressChanged(SeekBar seekBar, int i, boolean wasUserInput) { point = i; if (started && i > 0 && wasUserInput) { startPoint = new Integer(i); started = false; } } @Override public void onStartTrackingTouch(SeekBar seekBar) { } @Override public void onStopTrackingTouch(SeekBar seekBar) { if (point > 90 && startPoint < 20) { // slided to the right correctly. // TODO:: } else { // reset. resetSeekBar(seekBar, point); } startPoint = 0; started = true; } });

和：

/**
 * Resetting the seekbar, on point at a time.
 * @param seekBar                           Reference to the seekbar made smaller.
 * @param oldPoint                          The point where the dot is atm.
 */
private void resetSeekBar(final SeekBar seekBar, final int oldPoint) {
    if (oldPoint > 0) {
        final int newPoint = oldPoint -1;
        seekBar.setProgress(newPoint);

        timer.schedule(new TimerTask() {
            final SeekBar seekBar = seekBarBid;
            @Override
            public void run() {
                resetSeekBar(seekBar, newPoint);
            }
        }, 3);

    } else {
        seekBar.setProgress(oldPoint);
    }
}

我希望下面的答案是工作，

    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"?>
