How can we increase the font size in toast?

问题:

Is there any way to increase the font size in toast without customizing?

I don't want to create a layout for increasing the text size.

Is there any way?

Thanks,

Niki

I believe it is achieveable by this:

    ViewGroup group = (ViewGroup) toast.getView();
    TextView messageTextView = (TextView) group.getChildAt(0);
    messageTextView.setTextSize(25);

this is ...

 Toast toast = Toast.makeText(context, R.string.yummyToast, Toast.LENGTH_SHORT);
//the default toast view group is a relativelayout
RelativeLayout toastLayout = (RelativeLayout) toast.getView();
TextView toastTV = (TextView) toastLayout.getChildAt(0);
toastTV.setTextSize(30);
toast.show();

Here is how to do that with spans:

SpannableStringBuilder biggerText = new SpannableStringBuilder(text);
biggerText.setSpan(new RelativeSizeSpan(1.35f), 0, text.length(), 0);
Toast.makeText(context, biggerText, Toast.LENGTH_LONG).show();

You can't increase the font size without creating a CustomToastView.

This is a related question.

Working from Ani's answer, another solution that allows you to set the text size to a dimension value would be something like:

public static void showToast(Context context, int resId) {
    Toast toast = Toast.makeText(context, resId, Toast.LENGTH_LONG);
    LinearLayout toastLayout = (LinearLayout) toast.getView();
    TextView toastTV = (TextView) toastLayout.getChildAt(0);
    toastTV.setTextSize(TypedValue.COMPLEX_UNIT_PX,
            context.getResources().getDimension(R.dimen.TEXT_SIZE));
    toast.show();
}

This lets you match the size you get your toasts to be the same size as specified in TextView and Button controls, for example.

You can try to put the following code into your Manifest:

<supports-screens
android:anyDensity="true"
android:largeScreens="true"
android:normalScreens="true"
android:resizeable="true"
android:smallScreens="true"/> 

Put it above the <Application> element.
