2、Base类BaseSuspend

    }

    /**

     */
    public WindowManager.LayoutParams getParams() {

    }

    /**
     * 全屏显示悬浮视图
     */
    public void showSuspend() {
        showSuspend(0, 0, true);
    }

    /**
     * 显示悬浮视图
     *
     * @param sizeEntity
     * @param isMatchParent 是否全屏显示
     */
    public void showSuspend(SizeEntity sizeEntity, boolean isMatchParent) {
        if (sizeEntity != null) {
            showSuspend(sizeEntity.getWidth(), sizeEntity.getHeight(), isMatchParent);
        }
    }

    /**
     * 显示悬浮视图
     *
     * @param width
     * @param height
     */
    public void showSuspend(int width, int height, boolean isMatchParent) {
        //设置悬浮窗口长宽数据
        if (isMatchParent) {
            wmParams.width = WindowManager.LayoutParams.MATCH_PARENT;
            wmParams.height = WindowManager.LayoutParams.MATCH_PARENT;
        } else {
            wmParams.width = WindowManager.LayoutParams.WRAP_CONTENT;
            wmParams.height = WindowManager.LayoutParams.WRAP_CONTENT;
        }
        //悬浮窗的开始位置,读取缓存
        wmParams.x = width;
        wmParams.y = height;

        if (isShowing) {
            removeView();
        }
        mWindowManager.addView(view, wmParams);
        isShowing = true;
    }

    /**
     * 更新当前视图的位置
     *
     * @param x 更新后的X轴的增量
     * @param y 更新后的Y轴的增量
     */
    public void updateSuspend(int x, int y) {
        if (view != null) {
            //必须是当前显示的视图才给更新
            WindowManager.LayoutParams layoutParams = (WindowManager.LayoutParams) view.getLayoutParams();
            layoutParams.x += x;
            layoutParams.y += y;
            mWindowManager.updateViewLayout(view, layoutParams);
        }
    }

    /**
     * 移除当前悬浮窗
     */
    public void dismissSuspend() {
        if (view != null) {
            mWindowManager.removeView(view);
            isShowing = false;
            if (onSuspendDismissListener != null) {
                onSuspendDismissListener.onDismiss();
            }
        }
    }

    public Context getContext() {
        return context;
    }

    public View getView() {
        return view;
    }

    /**
     * 是否正在显示
     *
     * @return
     */
    public boolean isShowing() {
        return isShowing;
    }

    /**
     * 移除弹窗的时候回调
     *
     * @param onSuspendDismissListener
     */
    public void setOnSuspendDismissListener(OnSuspendDismissListener onSuspendDismissListener) {
        this.onSuspendDismissListener = onSuspendDismissListener;
    }

    public interface OnSuspendDismissListener {
        public void onDismiss();
    }
}

还有里面用到的一个size类:


/**
 * 宽高实体
 * Created by 她叫我小渝 on 2016/11/4.
 */

public class SizeEntity {
    private int width;
    private int height;

    public SizeEntity(){}
    public SizeEntity(int width,int height){
        setWidth(width);
        setHeight(height);
    }


    public int getWidth() {
        return width;
    }

    public void setWidth(int width) {
        this.width = width;
    }

    public int getHeight() {
        return height;
    }

    public void setHeight(int height) {
        this.height = height;
    }
}

3、定制视图和使用

要实现的逻辑是,显示一个悬浮球,然后可以拖动移动悬浮球的位置,效果图:

然后新建一个类,LogoSuspend继承BaseSuspend,里面引用到了一些工具类就不贴出来了,用到的地方我会加上注释


/**
 * 悬浮球
 * Created by 她叫我小渝 on 2017/1/1.
 */

public class LogoSuspend extends BaseSuspend {

    /**
     * ui
     */
    private ImageView ivLogo;
    /**
     * 变量
     */
    private int width, height;
    private float mStartX, mStartY, mStopX, mStopY, touchStartX, touchStartY;
    private long touchStartTime;
    /**
     * 接口
     */
    private View.OnClickListener onClickListener;

    public LogoSuspend(Context context) {
        super(context);
    }


    @Override
    protected int getLayoutId() {
        return R.layout.suspend_logo;
    }

    @Override
    protected void initView() {
        ivLogo = findView(R.id.iv_logo);
        ivLogo.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent event) {
                final int action = event.getAction();
                mStopX = event.getRawX();
                mStopY = event.getRawY();
                switch (action) {
                    case MotionEvent.ACTION_DOWN:
                        // 以当前父视图左上角为原点
                        mStartX = event.getRawX();
                        mStartY = event.getRawY();
                        touchStartX = event.getRawX();
                        touchStartY = event.getRawY();
                        touchStartTime = DateUtil.getTimeForLong();//获取当前时间戳
                        break;
                    case MotionEvent.ACTION_MOVE:
                        width = (int) (mStopX - mStartX);
                        height = (int) (mStopY - mStartY);
                        mStartX = mStopX;
                        mStartY = mStopY;
                        updateSuspend(width, height);
                        break;
                    case MotionEvent.ACTION_UP:
                        width = (int) (mStopX - mStartX);
                        height = (int) (mStopY - mStartY);
                        updateSuspend(width, height);
                        WindowManager.LayoutParams layoutParams = (WindowManager.LayoutParams) getView().getLayoutParams();
                        SuspensionCache.setSuspendSize(getContext(), new SizeEntity(layoutParams.x + width, layoutParams.y + height));//缓存一下当前位置
                        if ((mStopX - touchStartX) < 30 && (mStartY - touchStartY) < 30 && (DateUtil.getTimeForLong() - touchStartTime) < 300) {
                            //左右上下移动距离不超过30的,并且按下和抬起时间少于300毫秒,算是单击事件,进行回调
                            if (onClickListener != null) {
                                onClickListener.onClick(view);
                            }
                        }
                        break;
                }
                return true;
            }
        });
    }

    @Override
    protected void onCreateSuspension() {

    }

    /**
     * 设置点击监听
     *
     * @param onClickListener
     */
    public void setOnClickListener(View.OnClickListener onClickListener) {
        this.onClickListener = onClickListener;
    }
}

布局文件syspend_logo.xml



    

因为Activity是有生命周期的,所以打开悬浮窗的Context上下文,不要用Activity的,而是用Service的

创建并注册一个Service,然后在onCreate方法中执行调用代码就好

@Override
    public void onCreate() {
        super.onCreate();
        ALog.e("服务已创建");

        if (logoSuspend == null) {
            logoSuspend = new LogoSuspend(this);
        }
        logoSuspend.showSuspend(SuspensionCache.getSuspendSize(this), false);//从缓存中提取上一次显示的位置
        logoSuspend.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //处理单击事件
            }
        });
    }

4、废话

    上面的例子,其实还是比较简单的,但一般开发对于悬浮球的需求并不算很大,Base类的话,目前只是最基础的东西,在开发的过程中,需要用到什么了再往里面加就好,问题不大。

    目前代码支持同时显示多个悬浮窗、悬浮球,主要用于在于悬浮窗交互的时候,直接弹出其他的交互界面(也是以悬浮窗的状态出现),但建议每一个页面都有关闭按钮或者做返回键关闭的相关操作,毕竟是显示在最前端的,要是关不掉就点哪里都没用,只能是强制关机了…………()&@()……()@#*¥)()@*#…………@#)()*¥)()…………
