现在我想允许用户将操作按钮移动到屏幕上的任何位置。然后，他可能会打开它并选择其中一个选项

上次我用视图对象而不是浮动ActionButton对象做了同样的事情，效果非常好。使用浮动操作按钮，它没有脱落

我做了两次尝试

1） 在第一个例子中，我将SetOnTouchListLiner设置为LayoutFater对象（就像我的视图示例中那样），但我唯一能做的就是向左或向右滑动屏幕，然后将按钮稍微向右或向左移动。当我按下按钮然后移动时，什么也没发生

2） 我还尝试将setOnTouchListiner直接设置为FloatingActionButton，但它甚至没有显示

我如何让用户移动浮动动作按钮

下面是查看对象的代码，下面是我尝试使用FloatingActionButton的第1次尝试

还有一句话：FlyingButton扩展服务，MaterialDesignDialog扩展活动。那是故意的。一般来说，我希望所有系统图标上都有一个按钮。由于MaterialDesignDialog不能按我所希望的那样工作，我扩展了Activity类，因为我怀疑问题出在扩展服务中

查看对象

我已经在我的项目中实现了这种类型的浮动按钮。我认为您的问题是由于
LayoutInflater
。不要在
WindowManager
中设置包含浮动按钮的视图。将浮动按钮直接设置到您的
WindowManager

以下是我的代码，它对我很有效：

public class notificationService extends Service{

private WindowManager windowManager;
WindowManager.LayoutParams params;
FloatingActionButton Abutton;
Context context;
public FloatingActionMenu menu;
private final IBinder noteBind = new NotificationBinder();

@Override
public boolean onUnbind(Intent intent){
    return false;
}
@Override
public IBinder onBind(Intent intent) {
    // TODO Auto-generated method stub
    return noteBind;
}

@Override
public void onCreate() {
    super.onCreate();

    windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

    Abutton = new FloatingActionButton(this);
    Abutton.setProgress(0,true);
    Abutton.setColorNormal(ResourcesCompat.getColor(getResources(),R.color.floatingButtonColor,null));
    Abutton.setColorPressed(ResourcesCompat.getColor(getResources(),R.color.floatingButtonColorPressed,null));
    Abutton.setColorRipple(ResourcesCompat.getColor(getResources(),R.color.floatingButtonColorRipple,null));


    Abutton.setImageResource(R.mipmap.pause_note);
    Abutton.setX(25);


    Abutton.setOnClickListener(new View.OnClickListener() {    //set onclick events here
        @Override
        public void onClick(View view) {

                // Handle your onClick event here.

        }
    });


    params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.TYPE_PHONE,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
            PixelFormat.TRANSLUCENT);

    params.gravity = Gravity.TOP | Gravity.LEFT;
    params.x = 0;
    params.y = 100;


    windowManager.addView(Abutton,params);  //directly add your floating button here.


    try {
        Abutton.setOnTouchListener(new View.OnTouchListener() {
            private WindowManager.LayoutParams paramsF = params;
            private int initialX;
            private int initialY;
            private float initialTouchX;
            private float initialTouchY;

            @Override public boolean onTouch(View v, MotionEvent event) {
                switch (event.getAction()) {
                    case MotionEvent.ACTION_DOWN:

                        // Get current time in nano seconds.

                        initialX = paramsF.x;
                        initialY = paramsF.y;
                        initialTouchX = event.getRawX();
                        initialTouchY = event.getRawY();
                        break;
                    case MotionEvent.ACTION_UP:
                        break;
                    case MotionEvent.ACTION_MOVE:
                        paramsF.x = initialX + (int) (event.getRawX() - initialTouchX);
                        paramsF.y = initialY + (int) (event.getRawY() - initialTouchY);
                        windowManager.updateViewLayout(Abutton, paramsF);
                        break;
                }
                return false;
            }
        });
    } catch (Exception e) {
        // TODO: handle exception
    }

}

@Override
public void onDestroy() {
    super.onDestroy();
    if (Abutton != null) windowManager.removeView(Abutton);
}
}
我只通过编程实现了这个按钮。因此，没有用于此的xml布局。希望这对您有所帮助：）

不幸的是，您的解决方案不起作用。按钮甚至没有出现。我也找不到您设置为按钮的方法。它是：setProgress（）、setColorNormal（）、setColorPressed（）、setColorRipple（）。这些问题无法解决。也许我们讨论不同的浮动动作按钮？我已经实现了这个浮动按钮。我发现在你的链接中，这个按钮也有描述。你添加了正确的依赖项吗？是的，我添加了<代码>依赖项{compilefiletree（dir:'libs'，include:['*.jar']）testCompile'junit:junit:4.12'compile'com.android.support:appcompat-v7:23.1.0'compile'com.android.support:design:23.1.0'compile'com.github.clans:fab:1.6.2'}那么问题出在哪里？你能添加错误日志吗？那是我的错。我导入了android.support.design.widget.FloatingActionButton而不是com.github.clans.fab.FloatingActionButton。现在可以看到方法，但是当谈到getColor方法时，它会说：
Error:（68,47）Error：非静态方法getColor（参考资料，int，Resources.Theme）不能从静态上下文引用
