You won't be able to make a 'tutorial step' pointing to a menu item if the activity has not ActionBar (it's obvious why... you haven't menu items).

If you want to center the circle in a view inside your activity/fragment, this should work for you.

<pre><code>ShowcaseView.Builder res = new ShowcaseView.Builder(activity, true)
 .setTarget(target)
 .setContentTitle("title")
 .setContentText("content");
</code></pre>

Where target is:

<pre><code>Target target = new ViewTarget(view_id, activity)
</code></pre>

blocks|key|283654|text|我通过以下代码(分段)解决了类似的问题：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|283655|++++++++new+ShowcaseView.Builder(getActivity())

I solve my similar problem by this code (in fragment):

<pre><code> 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();
</code></pre>

blocks|key|283658|text|如果您想在overflowMenu上显示提示，那么可以尝试使用ShowCaseView#setTarget(目标t)设置以下目标：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|283659|Target+=+new+Target()+{

++++public+Point+getPoint()+{

if you want to show hint at overflowMenu then you can try setting the following target using ShowCaseView#setTarget(Target t):

<pre><code>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);
 }
};
</code></pre>

blocks|key|283667|text|看起来Showcase不能很好地使用Android热部署功能(可能是因为通货再膨胀的使用)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|283668|当我清理项目并重新启动时(在使用了正确的展示生成器之后)，它就成功了。|283669|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

It Looks like Showcase does not play well with the Android Studio hot deploy feature (maybe because of the reflation use).

When I cleaned the project, and restarted (after using the correct showcase builder), it worked.

blocks|key|196489|text|我有个解决办法..。Appcompat工具程序代码|type|unstyled|depth|inlineStyleRanges|entityRanges|data|196490|toolbar+=+(Toolbar)+findViewById(R.id.department_name);

I get a solution.....
Code for Appcompat toolber

<pre><code>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);
</code></pre>

Then use your preferred targetview library.I write here this by two different library.One is

<pre><code> 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();
</code></pre>

That's all.Happy coding......

Is there any way to use <a href="https://github.com/amlcurran/ShowcaseView" rel="nofollow">ShowcaseView</a> if the application has a theme Theme.AppCompat.Light.NoActionBar and using android.support.v7.widget.Toolbar in the application. I am getting below stack trace while executing the app. Please suggest...
