Question

我正在为我的应用程序使用此循环菜单。 https://github.com/oguzbilgener/CircularFloatingActionMenu 这是工作。但是当我打开导航抽屉时。此菜单位于前面。如何使菜单返回导航抽屉。

如何将导航抽屉放在前面？

            ImageView fabIconStar = new ImageView(this);
            fabIconStar.setImageDrawable(getResources().getDrawable(R.drawable.ic_action_headphones));

            FloatingActionButton.LayoutParams starParams = new FloatingActionButton.LayoutParams(FrameLayout.LayoutParams.WRAP_CONTENT, FrameLayout.LayoutParams.WRAP_CONTENT);
            starParams.setMargins(redActionButtonMargin, redActionButtonMargin, redActionButtonMargin, redActionButtonMargin);
            fabIconStar.setLayoutParams(starParams);

            FloatingActionButton.LayoutParams fabIconStarParams = new FloatingActionButton.LayoutParams(redActionButtonContentSize, redActionButtonContentSize);
            fabIconStarParams.setMargins(redActionButtonContentMargin, redActionButtonContentMargin, redActionButtonContentMargin, redActionButtonContentMargin);

            FloatingActionButton leftCenterButton = new FloatingActionButton.Builder(this).setContentView(fabIconStar, fabIconStarParams).setBackgroundDrawable(R.drawable.button_action_red_selector).setPosition(FloatingActionButton.POSITION_TOP_CENTER).setLayoutParams(starParams).build();

            // Set up customized SubActionButtons for the right center menu

            lCSubBuilder.setLayoutParams(blueContentParams);
            // Set custom layout params
            FrameLayout.LayoutParams blueParams = new FrameLayout.LayoutParams(blueSubActionButtonSize, blueSubActionButtonSize);
            lCSubBuilder.setLayoutParams(blueParams);

            ImageView lcIcon1 = new ImageView(this);

这与my answer here非常相似，只对FloatingActionButton实例化进行了少量更改。

库代码假定按钮和菜单显示在活动内容视图的顶部，以及其中的所有内容。在FloatingActionButton类中添加容器ViewGroup成员允许我们将子ViewGroup指定为父类。请注意，只有在菜单中使用FloatingActionButton时，以下更改才有效。

FloatingActionButton类的补充：

public class FloatingActionButton extends FrameLayout {
    ...
    private ViewGroup containerView;
    ...
    public FloatingActionButton(Activity activity, 
                                LayoutParams layoutParams, 
                                int theme,
                                Drawable backgroundDrawable,
                                int position,
                                View contentView,
                                FrameLayout.LayoutParams contentParams      
                                // Note the addition of the following
                                // constructor parameter here
                                , ViewGroup containerView) {
        ...
        setClickable(true);

        // This line is new. The rest of the constructor is the same.
        this.containerView = containerView;     

        attach(layoutParams);
    }
    ...
    public View getActivityContentView() {
        if(containerView == null) {
            return ((Activity)getContext())
                .getWindow().getDecorView().findViewById(android.R.id.content);
        } else {
            return containerView;
        }
    }

    public ViewGroup getContainerView() {
        return containerView;
    }

    // The following setter is not strictly necessary, but may be of use
    // if you want to toggle the Button's and Menu's z-order placement
    public void setContainerView(ViewGroup containerView) {
        this.containerView = containerView;
    }
    ...
    public static class Builder {
        ...
        private ViewGroup containerView;
        ...
        public Builder setContainerView(ViewGroup containerView) {
            this.containerView = containerView;
            return this;
        }

        public FloatingActionButton build() {
            return new FloatingActionButton(activity,
                                            layoutParams,
                                            theme,
                                            backgroundDrawable,
                                            position,
                                            contentView,
                                            contentParams,
                                            // New argument
                                            containerView);
        }
    }
    ...
}

FloatingActionMenu类的更改：

public class FloatingActionMenu {
    ...
    public View getActivityContentView() {
        if(mainActionView instanceof FloatingActionButton && 
            ((FloatingActionButton) mainActionView).getContainerView() != null) {
            return ((FloatingActionButton) mainActionView).getContainerView();
        } else {
            return ((Activity)mainActionView.getContext())
                .getWindow().getDecorView().findViewById(android.R.id.content);
        }
    }
    ...
}

然后，假设您的Activity的布局类似于：

<android.support.v4.widget.DrawerLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    ...>

    <FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
    ...
</android.support.v4.widget.DrawerLayout>

在Home活动中，您将构建并实例化leftCenterButton，如下所示：

public class Home extends Activity implements OnClickListener {
    ...
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...
        FrameLayout container = (FrameLayout) findViewById(R.id.container);

        FloatingActionButton leftCenterButton = new FloatingActionButton.Builder(this)
            .setContentView(fabIconStar, null)
            .setBackgroundDrawable(R.drawable.ic_launcher)
            .setPosition(FloatingActionButton.POSITION_TOP_CENTER)
            .setLayoutParams(starParams)
            // The new method call is added here
            .setContainerView(container)
            .build();
        ...
    }
    ...
}

如何将我的导航抽屉带到前面？
