Question

如果应用程序在应用程序中有主题Theme.AppCompat.Light.NoActionBar并使用android.support.v7.widget.Toolbar，是否有任何方法可以使用ShowcaseView。我在执行应用程序时遇到堆栈跟踪。请建议......

Answer 1

您无法进行教学步骤＆＃39;如果活动没有ActionBar，则指向一个菜单项（这显然是为什么......你还没有菜单项）。

如果您想将圆圈置于活动/片段内的视图中心，这应该适合您。

ShowcaseView.Builder res = new ShowcaseView.Builder(activity, true)
                .setTarget(target)
                .setContentTitle("title")
                .setContentText("content");

目标是：

Target target = new ViewTarget(view_id, activity)

Answer 2

我通过这段代码解决了我的类似问题（片段中）：

        new ShowcaseView.Builder(getActivity())
    .setTarget( new ViewTarget( ((View) parentView.findViewById(R.id.link_to_register)) ) )
    .setContentTitle("ShowcaseView")
    .setContentText("This is highlighting the Home button")
    .hideOnTouchOutside()
    .build();

Answer 3

如果你想在overflowMenu上显示提示，那么你可以尝试使用ShowCaseView＃setTarget（Target t）设置以下目标：

Target = new Target() {
    @Override
    public Point getPoint() {
        int[] location = new int[2];
        toolBar.getLocationInWindow(location);
        int x = location[0] + toolBar.getWidth() - toolBar.getHeight() / 2;
        int y = location[1] + toolBar.getHeight() / 2;
        return new Point(x, y);
    }
};

我有解决办法..... Appcompat工具员的代码

toolbar = (Toolbar) findViewById(R.id.department_name);
    toolbar.setTitle(R.string.catagory_one);
    toolbar.setSubtitle(getText(R.string.lwebsite));
    toolbar.inflateMenu(R.menu.all_articles);// add this line catching menu items
    setSupportActionBar(toolbar);

然后使用您首选的targetview库。我在这里由两个不同的库编写。一个是

 new MaterialTapTargetPrompt.Builder(CatagoryOne_HOME.this)//library link:https://github.com/sjwall/MaterialTapTargetPrompt
            .setTarget(R.id.sync)//this is yours
            .setPrimaryText("Send your first email")
            .setSecondaryText("Tap the envelope to start composing your first email")
            .show();

    ViewTarget target = new ViewTarget(toolbar.findViewById(R.id.sync));//this is yours
    new ShowcaseView.Builder(this)
            .setContentTitle("Its My Navigation Drawer")
            .setContentText("Click here and you will get options to navigate to other sections.")
            .useDecorViewAsParent() 
            .setTarget(target)
            .build();

仅此而已。快乐的编码...
