A SeekBar suited for showing a preview of something. As seen in Google Play Movies.
Add the following to your app's build.gradle:
dependencies {
// Base implementation with a standard SeekBar
implementation 'com.github.rubensousa:previewseekbar:2.0.0'
// ExoPlayer extension that contains a TimeBar.
implementation 'com.github.rubensousa:previewseekbar-exoplayer:2.8.1.0'
}If you're going to use this with ExoPlayer, you need both dependencies.
<FrameLayout
android:id="@+id/previewFrameLayout"
android:layout_width="@dimen/video_preview_width"
android:layout_height="@dimen/video_preview_height">
<ImageView
android:id="@+id/imageView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/colorPrimary" />
</FrameLayout>
<com.github.rubensousa.previewseekbar.PreviewSeekBar
android:id="@+id/previewSeekBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="25dp"
android:max="800" />// Create a class that implements this interface and implement your own preview logic there
public interface PreviewLoader {
void loadPreview(long currentPosition, long max);
}
PreviewLoader loader = new ExoPlayerLoader();
previewSeekBarLayout.setup(loader);<com.google.android.exoplayer2.ui.SimpleExoPlayerView
android:id="@+id/player_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:controller_layout_id="@layout/exoplayer_controls"/>Here's the sample's exoplayer_controls: https://github.com/rubensousa/PreviewSeekBar/blob/master/sample/src/main/res/layout/exoplayer_controls.xml
The PreviewSeekBarLayout inside exoplayer_controls should be similar to this:
<FrameLayout
android:id="@+id/previewFrameLayout"
android:layout_width="@dimen/video_preview_width"
android:layout_height="@dimen/video_preview_height"
android:background="@drawable/video_frame"
android:padding="@dimen/video_frame_width">
<ImageView
android:id="@+id/imageView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</FrameLayout>
<com.github.rubensousa.previewseekbar.exoplayer.PreviewTimeBar
android:id="@+id/exo_progress"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:previewFrameLayout="@id/previewFrameLayout"/>In this sample, Glide is used with a custom transformation to crop the thumbnails from a thumbnail sprite.
@Override
public void loadPreview(long currentPosition, long max) {
player.setPlayWhenReady(false);
GlideApp.with(imageView)
.load(thumbnailsUrl)
.override(GlideThumbnailTransformation.IMAGE_WIDTH,
GlideThumbnailTransformation.IMAGE_HEIGHT)
.transform(new GlideThumbnailTransformation(currentPosition))
.into(imageView);
