The Translations Editor provides a consolidated and editable view of all of your default and translated string resources. For an introduction to translating your app for different languages, read Supporting different languages and cultures.

Figure 1. The Translations Editor showing app text before translation. The string resources for a project are contained in strings. Your project has a default strings.

You can also have translated strings. Once you have your default strings. Either way, you should take advantage of the Android Studio features to help you manage and test localizable text. For information about professional translation services, see Order translation services. The Translations Editor displays the key and value pairs from the strings. Note: When you have translated strings. Your default strings. Figure 1 shows the default app text in this case, English in the Translations Editor for a simple app before translation work has been done.

The contents of translated strings. You can access the Translations Editor from within any of your strings. Note: If you click the Hide notification link, the Open editor link goes away. To bring it back, close and reopen the project. You can open the Translations Editor from the Layout Editor's Design Editor to edit your default and translated text to better fit your layout. For information about switching languages in the Design Editor, see Display translated text in the Design Editor.

In the Translations Editor , you can select Unstranslatable to indicate that you do not want the text in this row to be translated. Text that you would not want translated might be product-specific text like trade names and trade marks, or technical terms that do not have a translation. When you check Untranslatable , the corresponding line in the default strings.

In the following example, EasyApp in the top line is not translated because it is the product name. The Translations Editor supports BCP 47 and combines locale and region country codes into a single selection for targeted localizations.

A locale defines more than the language. A locale includes country-dependent formatting for things like the date and time, currencies, and decimals. For example, values-es for Spanish. You can delete a language in the Translations Editor by deleting every value in the column see Edit, add, or delete text , or you can delete the project folder for that language, as follows:. You can operate on the text settings directly in the strings.

This section describes the Translations Editor approach. In the Translations Editor , you can edit, add, or delete text through the list view or through the Translation field at the bottom of the Translations Editor. Figure 2. List view on the top and the Translation field on the bottom. In the Translations Editor, the Key column lists the unique identifiers for each data item in your strings.

You can add and delete keys through the Translations Editor. When you delete a key, the Translations Editor deletes it and all of its associated translations. When you run this animation, it doesn't look very good. After the moon reaches the top of the arc, it starts jumping around.

To understand the bug, consider what happens when the user is touching just below the top of the arc. But, since the bottom of the moon doesn't always go in the same direction, it goes up then comes back down, MotionLayout doesn't know what to do when the user has just passed the top of the arc.

To consider this, since you're tracking the bottom of the moon, where should it be placed when the user is touching here? To avoid bugs like this, it is important to always choose a touchAnchorId and touchAnchorSide that always progresses in one direction throughout the duration of the entire animation. In this animation, both the right side and the left side of the moon will progress across the screen in one direction.

However, both the bottom and the top will reverse direction. When OnSwipe attempts to track them, it will get confused when their direction changes. You can also combine dragDirection with touchAnchorSide to make a side track a different direction than it normally would. It's still important that the touchAnchorSide only progresses in one direction, but you can tell MotionLayout which direction to track.

This will cause MotionLayout to track the position of the bottom of the view, but only consider its location when moving right it ignores vertical motion.

So, even though the bottom goes up and down, it will still animate correctly with OnSwipe. MotionLayout can be used to build rich animations when used with CoordinatorLayout. In this step, you'll build a collapsible header using MotionLayout. That's how you implement a collapsing toolbar like this on Android—the scrolling of the text will be "coordinated" with the collapsing header.

However, the OnSwipe declaration was removed to enable it to work with CoordinatorLayout. This code will register a OnOffsetChangedListener that will be called every time the user scrolls with the current scroll offset. MotionLayout supports seeking its transition by setting the progress property. To convert between a verticalOffset and a percentage progress, divide by the total scroll range. It's possible to build custom dynamic collapsing toolbar animations using MotionLayout.

By using a sequence of KeyFrames you can achieve very bold effects. To see more examples of MotionLayout in practice, check out the official sample. And be sure to check out the documentation! MotionLayout supports even more features not covered in this codelab, like KeyCycle, which lets you control paths or attributes with repeating cycles, and KeyTimeCycle, which lets you animate based on clock time.

Check out the samples for examples of each. For links to other codelabs in this course, see the Advanced Android in Kotlin codelabs landing page.

Before you begin This codelab is part of the Advanced Android in Kotlin course. Animations are a great way to enhance an app experience. You can use animations to: Show changes —animating between states lets the user naturally track changes in your UI.

Draw attention —use animations to draw attention to important UI elements. Build beautiful designs —effective motion in design makes apps look polished.

Prerequisites This codelab has been designed for developers with some Android development experience. Before attempting to complete this codelab, you should: Know how to create an app with an activity, a basic layout, and run it on a device or emulator using Android Studio.

Be familiar with ConstraintLayout. Read through the Constraint Layout codelab to learn more about ConstraintLayout. Getting Started To download the sample app, you can either: Download Zip Creating animations with MotionLayout First, you'll build an animation that moves a view from the top start of the screen to the bottom end in response to user clicks.

To create an animation from the starter code, you'll need the following major pieces: A MotionLayout, which is a subclass of ConstraintLayout. You specify all the views to be animated inside the MotionLayout tag. A Transition, which is part of the MotionScene that specifies the animation duration, trigger, and how to move the views. A ConstraintSet that specifies both the start and the end constraints of the transition.

Step 1: Explore the existing code MotionLayout is a subclass of ConstraintLayout , so it supports all the same features while adding animation.

Here you have a ConstraintLayout with a single ImageView of a star, with a tint applied inside of it. For your layout to use a motion scene, it has to point at it. To do this, open the design surface. In Android Studio 4. Once you open the design surface, right click the preview and select Convert to MotionLayout. As soon as you convert to a MotionLayout , the design surface will display Motion Editor There are three new UI elements in the Motion Editor: Overview — This is a modal selection that allows you to select different parts of the animation.

In this image the start ConstraintSet is selected. You can also select the transition between start and end by clicking on the arrow between them. Section — Below the overview is a section window that changes based on the currently selected overview item. In this image, the start ConstraintSet information is displayed in the selection window. Attribute — The attribute panel shows and allows you to edit the attributes of the current selected item from either the overview or selection window.

In this image, it's showing the attributes for the start ConstraintSet. Step 3: Define start and end constraints All animations can be defined in terms of a start and an end. Currently it shows Source of layout — this means it's not constrained in this ConstraintSet. Select the end ConstraintSet in the overview panel. Step 4: Define a transition Every MotionScene must also include at least one transition. Motion Editor created a transition for us by default when it created the MotionScene file.

Looking at each attribute: constraintSetStart will be applied to the views as the animation starts. Step 5: Preview animation in Motion Editor Animation: Video of playing a transition preview in Motion Editor Open Motion Editor and select the transition by clicking on the arrow between start and end in the overview panel.

The selection panel shows playback controls and a scrub bar when a transition is selected. Click play or drag the current position to preview the animation. Step 6: Add an on click handler You need a way to start the animation.

Open up the motion editor and select the transition by clicking on the arrow between start and end in the overview panel. Click Create click or swipe handler in the toolbar for the overview panel. This adds a handler that will start a transition.

Click Add the click handler is represented by a small dot on the Transition in Motion Editor. With the transition selected in the overview panel, add a clickAction attribute of toggle to the OnClick handler you just added in the attributes panel. Looking at each attribute: targetId is the view to watch for clicks. You can see other options for clickAction in the documentation. Reveal will reveal the clean frame image wherever you touch the image, whereas the conceal brush will restore the original frame image.
