Use Toast inside Fragment

I'm trying to show a Toast Message when user click on a Button inside a Fragment. The problem is I cannot access the activity to show the Toast on it.

Here's the source of Fragment:

    public class FrgTimes extends Fragment
    {
    	ScrollView sv;
    	public View onCreateView(LayoutInflater inflater, ViewGroup container,
    			Bundle savedInstanceState) 
    	{
    		if (container == null) { return null; }
    
    		sv = (ScrollView)inflater.inflate(R.layout.frg_times, container, false);
 
            btnTime1.setOnClickListener(new OnClickListener() {
			public void onClick(View v) {

            //******  HERE's the PROBLEM  ********
			Toast.makeText(<The Activity>, "Please long press the key", Toast.LENGTH_LONG );

			}});

            return sv;
        }

and Here's what I've been tried.

Toast.makeText( getActivity()  , ...
Toast.makeText( getView().getContext()  , ...
Toast.makeText( getActivity().getApplicationContext()  , ...
Toast.makeText( sv.getContext()  , ...
Toast.makeText( sv.getRootView().getContext()  , ...

In Debug I can see that all of these codes run without any exception but no TOAST being displayed.

You are not calling show() on the Toast you are creating with makeText().

As stated by alfo888_ibg:

@Override
public void onClick(View arg0) {
   Toast.makeText(activity,"Text!",Toast.LENGTH_SHORT).show();
}

Just do:

    Toast.makeText(getActivity(),"Text!",Toast.LENGTH_SHORT).show();

this worked for me.

To help another people with my same problem, the complete answer to Use Toast inside Fragment is:

Activity activity = getActivity();

@Override
public void onClick(View arg0) {
	 
    Toast.makeText(activity,"Text!",Toast.LENGTH_SHORT).show();
}
	 

When making a toast in fragment do as following:

Toast.makeText(getActivity(),"Message", Toast.LENGTH_SHORT).show();

When class is extending fragment it is necessary to use getActivity() since fragment is a subclass of activity.

Cheerse

You can get the current activity with getActivity()

Toast.makeText(getActivity(),"Toast your message" ,Toast.LENGTH_SHORT).show();

Making a Toast inside Fragment

 Toast.makeText(getActivity(), "Your Text Here!", Toast.LENGTH_SHORT).show();

OR

    Activity activityObj = this.getActivity();

    Toast.makeText(activityObj, "Your Text Here!", Toast.LENGTH_SHORT).show();

OR

Toast.makeText(this, "Your Text Here!", Toast.LENGTH_SHORT).show();

If you are using kotlin then the context will be already defined in the fragment. So just use that context. Try the following code to show a toast message.

Toast.makeText(context , "your_text", Toast.LENGTH_SHORT).show()

When calling Toast inside android fragment:

1. Activity mActivity=this.getActivity();  

2. Toast.makeText(mActivity,"Text you want to display",Toast.LENGTH_SHORT).show();

This works for me.

user2564789 said it right
But you can also use this in the place of getActivity()
which will make your toast look like this

Toast.makeText(this,"Message",Toast.LENGTH_SHORT).show();

A simple [Fragment] subclass.
Kotlin!
contextA - is a parent (main) Activity. Set it on create object.

class Start(contextA: Context) : Fragment() {

var contextB: Context = contextA;

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    // Inflate the layout for this fragment
    val fl = inflater.inflate(R.layout.fragment_start, container, false)

	// only thet variant is worked on me
    fl.button.setOnClickListener { view -> openPogodaUrl(view) }

    return fl;
}

fun openPogodaUrl(view: View) {        
    try {
        pogoda.webViewClient = object : WebViewClient() { // pogoda - is a WebView
            override fun shouldOverrideUrlLoading(view: WebView?, url: String?): Boolean {
                view?.loadUrl(url)
                return true
            }
        }
        pogoda.loadUrl("http://exemple.com/app_vidgets/pogoda.html");
    }
    catch (e: Exception)
    {
        Toast.makeText(contextB, e.toString(), Toast.LENGTH_LONG).show();
    }
}

}

Using Kotlin

Toast.makeText(view!!.context , "your_text", Toast.LENGTH_SHORT).show()

In Kotlin android Toast.makeText(activity!!, "Your Text Here!", Toast.LENGTH_SHORT).show()

        public void onClick(View v) {
            Context context = v.getContext();
            CharSequence text = "Message";
            int duration = Toast.LENGTH_SHORT;
            Toast toast = Toast.makeText(context, text, duration);
            toast.show();
        }

Unique Approach

(Will work for Dialog, Fragment, Even Util class etc...)

ApplicationContext.getInstance().toast("I am toast");

Add below code in Application class accordingly.

public class ApplicationContext extends Application {

private static ApplicationContext instance;

@Override
public void onCreate() {
    super.onCreate();
    instance = this;
}

public static void toast(String message) {
    Toast.makeText(getContext(), message, Toast.LENGTH_SHORT).show();
}
}
