首先在android中启动Tutorial

首先在android中启动Tutorial - 用片段显示案例视图(First launch Tutorial in android - Show case view with fragment)

经过大量搜索，我在Github上找到了一个很好的存储库 ，显示了我想要的东西，但问题是我在我的应用程序中使用了片段，我不知道如何使用库！ 在我的第一次尝试它给我跟随错误

"java.lang.IllegalArgumentException: width and height must be > 0"

我在这里找到了一个解决方案，但现在它没有显示任何东西。（事实上，演示屏幕没有显示）可以提供一段与片段一起工作正常的代码吗？ 或者帮我解决这个问题？

谢谢。

After searching a lot I found a nice repository on Github which show something that i want , but the problem is I use fragments in my app and i don't know how to use library ! in my first attemp it gives me following Error

"java.lang.IllegalArgumentException: width and height must be > 0"

I found a solution HERE but now it doesn't show something.( in fact demo screen doesn't show up ) can any give a piece of code which works fine with fragment ? or help me how to solve this ?

Thanks.

嘿，男人刚刚为你做了样品

我真的没有做任何事只是使用onCreateView中的库，它工作

@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_main, container, false); new ShowcaseView.Builder(getActivity()) .setTarget(new ActionViewTarget(getActivity(), ActionViewTarget.Type.HOME)) .setContentTitle("ShowcaseView") .setContentText("This is highlighting the Home button") .hideOnTouchOutside() .build(); return rootView; }

评论中的问题更新

只需在onActivityCreated方法上添加代码，检查创建的示例

public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); if (savedInstanceState==null){ View view = getActivity().findViewById(R.id.hometxv); view.post(new Runnable() { @Override public void run() { if (isAdded()) { ShowcaseView sv; ViewTarget target=new ViewTarget(R.id.hometxv,getActivity()); RelativeLayout.LayoutParams lps = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT); lps.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM); lps.addRule(RelativeLayout.ALIGN_PARENT_LEFT); int margin = ((Number) (getResources().getDisplayMetrics().density * 12)).intValue(); lps.setMargins(margin, margin, margin, margin); sv = new ShowcaseView.Builder(getActivity(), true) .setTarget(target) .setContentTitle("hold up") .setContentText("smoke weed everyday") .setShowcaseEventListener(new OnShowcaseEventListener() { @Override public void onShowcaseViewHide(ShowcaseView showcaseView) { } @Override public void onShowcaseViewDidHide(ShowcaseView showcaseView) { } @Override public void onShowcaseViewShow(ShowcaseView showcaseView) { } }) .build(); sv.setButtonPosition(lps); } } }); } }

享受：D

hey man just made a sample here for you

i literally done nothing just used the library inside the onCreateView and it worked

@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_main, container, false); new ShowcaseView.Builder(getActivity()) .setTarget(new ActionViewTarget(getActivity(), ActionViewTarget.Type.HOME)) .setContentTitle("ShowcaseView") .setContentText("This is highlighting the Home button") .hideOnTouchOutside() .build(); return rootView; }

Update for the question in the comment

just add your code on the onActivityCreated method check the sample created

public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); if (savedInstanceState==null){ View view = getActivity().findViewById(R.id.hometxv); view.post(new Runnable() { @Override public void run() { if (isAdded()) { ShowcaseView sv; ViewTarget target=new ViewTarget(R.id.hometxv,getActivity()); RelativeLayout.LayoutParams lps = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT); lps.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM); lps.addRule(RelativeLayout.ALIGN_PARENT_LEFT); int margin = ((Number) (getResources().getDisplayMetrics().density * 12)).intValue(); lps.setMargins(margin, margin, margin, margin); sv = new ShowcaseView.Builder(getActivity(), true) .setTarget(target) .setContentTitle("hold up") .setContentText("smoke weed everyday") .setShowcaseEventListener(new OnShowcaseEventListener() { @Override public void onShowcaseViewHide(ShowcaseView showcaseView) { } @Override public void onShowcaseViewDidHide(ShowcaseView showcaseView) { } @Override public void onShowcaseViewShow(ShowcaseView showcaseView) { } }) .build(); sv.setButtonPosition(lps); } } }); } }

enjoy :D
