Toasty

一个创建自定义Toast的库。正如作者所说，这个库是：
The usual Toast, but with steroids.

Toasty Android Studio编写

从Github下载，直接导入 Import Project运行

实现在Module:toasty中，实例在Module:app中

Toasty 7中具体实例

1、To display an error Toast:

Toasty.error(yourContext, "This is an error toast.", Toast.LENGTH_SHORT, true).show();

2、To display a success Toast:

Toasty.success(yourContext, "Success!", Toast.LENGTH_SHORT, true).show();

3、To display an info Toast:

Toasty.info(yourContext, "Here is some info for you.", Toast.LENGTH_SHORT, true).show();

4、To display a warning Toast:

Toasty.warning(yourContext, "Beware of the dog.", Toast.LENGTH_SHORT, true).show();

5、To display the usual Toast:

Toasty.normal(yourContext, "Normal toast w/o icon").show();

6、To display the usual Toast with icon:

Toasty.normal(yourContext, "Normal toast w/ icon", yourIconDrawable).show();

7、You can also create your custom Toasts with the custom() method:

Toasty.custom(yourContext, "I'm a custom Toast", yourIconDrawable, textColor, tintColor, duration, withIcon, true).show();

There are variants of each method, feel free to explore this library.

前六种都是使用Toasty中custom方法实现，根本实现还是Toast。

final Toast currentToast = new Toast(context);final View toastLayout = ((LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.toast_layout, null);

ToastyUtils .java

final class ToastyUtils {    private ToastyUtils() {    }    static Drawable tint9PatchDrawableFrame(@NonNull Context context, @ColorInt int tintColor) {        final NinePatchDrawable toastDrawable = (NinePatchDrawable) getDrawable(context, R.drawable.toast_frame);        toastDrawable.setColorFilter(new PorterDuffColorFilter(tintColor, PorterDuff.Mode.SRC_IN));        return toastDrawable;    }    static void setBackground(@NonNull View view, Drawable drawable) {        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {            view.setBackground(drawable);        } else {            view.setBackgroundDrawable(drawable);        }    }    static Drawable getDrawable(@NonNull Context context, @DrawableRes int id) {        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {            return context.getDrawable(id);        } else {            return context.getResources().getDrawable(id);        }    }}

Toasty根本方法

Toast custom(@NonNull Context context, @NonNull String message, Drawable icon,                 @ColorInt int textColor, @ColorInt int tintColor, int duration,                 boolean withIcon, boolean shouldTint) {        final Toast currentToast = new Toast(context);        final View toastLayout = ((LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE))                .inflate(R.layout.toast_layout, null);        final ImageView toastIcon = (ImageView) toastLayout.findViewById(R.id.toast_icon);        final TextView toastTextView = (TextView) toastLayout.findViewById(R.id.toast_text);        Drawable drawableFrame;        if (shouldTint) {            drawableFrame = ToastyUtils.tint9PatchDrawableFrame(context, tintColor);        } else {            drawableFrame = ToastyUtils.getDrawable(context, R.drawable.toast_frame);        }        ToastyUtils.setBackground(toastLayout, drawableFrame);        if (withIcon) {            if (icon == null) {                throw new IllegalArgumentException("Avoid passing 'icon' as null if 'withIcon' is set to true");            }            ToastyUtils.setBackground(toastIcon, icon);        } else {            toastIcon.setVisibility(View.GONE);        }        toastTextView.setTextColor(textColor);        toastTextView.setText(message);        toastTextView.setTypeface(Typeface.create(TOAST_TYPEFACE, Typeface.NORMAL));        currentToast.setView(toastLayout);        currentToast.setDuration(duration);        return currentToast;    }

Drawable yourIconDrawable = getResources().getDrawable(R.drawable.ic_pets_white_48dp);Toasty.custom(MainActivity.this, "I'm a custom Toast", yourIconDrawable, Color.GREEN, Color.CYAN, 3000, true, true).show();
