Center text in a Toast

Question

I was wondering if there was a way to display all text in a Toast to be centered. For instance, I have a Toast that has 2 lines of text in it. For purely aesthetic reasons, I would like the text to center-aligned instead of left-aligned. I've looked through the documentation and can't find anything about it. Is there a simple way to do this that I have missed?

Answer 1

Use the Toast's setView(view) function to supply a View with Gravity.CENTER.

What about APIs < 23? Does it matter? – Glorification

Answer 2

Adapted from another answer:

Toast toast = Toast.makeText(this, "Centered\nmessage", Toast.LENGTH_SHORT);
TextView v = (TextView) toast.getView().findViewById(android.R.id.message);
if( v != null) v.setGravity(Gravity.CENTER);
toast.show();

Why the default gravity is not Gravity.CENTER? Silly android! – Payment

I don't know why but I have failed this method on Android 11 (API-30). – Metrology

I haven't worked with Android for years, it's possible that Google disabled this possibility? – Twombly

Answer 3

Toast is built on a TextView and the default gravity of it is left aligned. So, you need to create your own TextView like this for instance :

<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:gravity="center_vertical|center_horizontal"
    android:text="all the text you want"
/>

And you assign the TextView to the Toast like this :

Toast t = new Toast(yourContext);
t.setView(yourNewTextView);

Without the hacks:

String text = "Some text";
Spannable centeredText = new SpannableString(text);
centeredText.setSpan(
    new AlignmentSpan.Standard(Layout.Alignment.ALIGN_CENTER),
    0, text.length() - 1,
    Spannable.SPAN_INCLUSIVE_INCLUSIVE
);

Toast.makeText(getActivity(), centeredText, Toast.LENGTH_LONG).show();

There are also another alignments besides center.

It still works on Android 11 (API-30). – Metrology

Answer 5

It is dirty hack, but

((TextView)((LinearLayout)toast.getView()).getChildAt(0))
    .setGravity(Gravity.CENTER_HORIZONTAL);

Great! Make sure you surround with a ClassCastException catch to be safe in case the view hierarchy of Toasts changes in the future. – Mcclung

This works on my Nexus 4. I suggest doing this, wrapping it with a ClassCastException as Max Howell said above and then live with it when it throws an actual exception. – Shortfall

use findViewById(android.R.id.message) on the view returned by toast.getView() to ensure working code on all versions – Guile

Answer 6

Toast toast = Toast.makeText(this, "Message", Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();

This does not center the text, but the toast's itself. – Inwrap

Answer 7

Not saing that findViewById(android.R.id.message) is wrong, but just in case there are (future?) implementation differences I myself used a bit differen approach:

void centerText(View view) {
    if( view instanceof TextView){
        ((TextView) view).setGravity(Gravity.CENTER);
    }else if( view instanceof ViewGroup){
        ViewGroup group = (ViewGroup) view;
        int n = group.getChildCount();
        for( int i = 0; i<n; i++ ){
            centerText(group.getChildAt(i));
        }
    }
}

and then:

Toast t = Toast.makeText(context, msg,Toast.LENGTH_SHORT);
centerText(t.getView());
t.show();

In kotlin:

fun makeToast(context: Context, resId: Int) {
    val toast = Toast.makeText(context, resId, Toast.LENGTH_SHORT)
    val view = toast.view.findViewById<TextView>(android.R.id.message)
    view?.let {
        view.gravity = Gravity.CENTER
    }
    toast.show()
}

Answer 9

It is work for me:

Toast toast = Toast.makeText(context, message, Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER| Gravity.BOTTOM, 0, 20);
toast.show();

This does not work for me. The text is still aligned to the left. – Cass

Answer 10

This variation is with using LinearLayout in your layout xml :)

Toast SampleToast = Toast.makeText(this, "This is the example of centered text.\nIt is multiline text.", Toast.LENGTH_SHORT);
LinearLayout OurLayout = (LinearLayout) SampleToast.getView();
    
if (OurLayout.getChildCount() > 0) {
   TextView SampleView = (TextView) OurLayout.getChildAt(0);
   SampleView.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);
}

SampleToast.show();

This is a hacky solution that might not work in future versions of android, for example if the first child is not a TextView. Does not follow Java coding standards. – Nipping

Answer 11

Toast t=Toast.makeText(getApplicationContext(),"Text",Toast.LENGTH_LONG);
t.setText("Password Does't match...");
t.setGravity(0, 0, 0);
t.show();

simple code for toast most be center

Welcome to SO. Please look through the help page on answering questions.. As written, your code is poorly formatted and does not contain an explanation. – Wiggler

Sorry, but your code set gravity center to the toast (it appear in center screen), not to the text – Farr
