From 338d6f29b112803f1c2fa8ce985c646e51ee76e8 Mon Sep 17 00:00:00 2001 From: Charles Lombardo Date: Sun, 27 Aug 2023 00:16:53 -0400 Subject: [PATCH] android: Properly adjust emulation surface aspect ratio Previously the emulation surface wouldn't respond properly to orientation changes. This would result in the screen appearing stretched when starting in one orientation and switching to another. The code for calculating the bounds of the view have been changed to match the expected behavior now. Before the view would just match parent in height and width. Now instead of using setLeftTopRightBottom (which is intended to be used for animations) we pass newly calculated bounds for the view into super. Now the view bounds match the emulation output. This also means that we don't need the overload for the SettingsActivity to launch it using an ActivityResultLauncher. We can just update the view in onResume. --- .../features/settings/ui/SettingsActivity.kt | 13 ----- .../yuzu_emu/fragments/EmulationFragment.kt | 17 +------ .../yuzu_emu/views/FixedRatioSurfaceView.kt | 48 ++++++++++++------- 3 files changed, 33 insertions(+), 45 deletions(-) diff --git a/src/android/app/src/main/java/org/yuzu/yuzu_emu/features/settings/ui/SettingsActivity.kt b/src/android/app/src/main/java/org/yuzu/yuzu_emu/features/settings/ui/SettingsActivity.kt index a5af5a7ae..e6fffc832 100644 --- a/src/android/app/src/main/java/org/yuzu/yuzu_emu/features/settings/ui/SettingsActivity.kt +++ b/src/android/app/src/main/java/org/yuzu/yuzu_emu/features/settings/ui/SettingsActivity.kt @@ -11,7 +11,6 @@ import android.view.View import android.view.ViewGroup.MarginLayoutParams import android.widget.Toast import androidx.activity.OnBackPressedCallback -import androidx.activity.result.ActivityResultLauncher import androidx.activity.viewModels import androidx.appcompat.app.AppCompatActivity import androidx.core.view.ViewCompat @@ -246,17 +245,5 @@ class SettingsActivity : AppCompatActivity(), SettingsActivityView { settings.putExtra(ARG_GAME_ID, gameId) context.startActivity(settings) } - - fun launch( - context: Context, - launcher: ActivityResultLauncher, - menuTag: String?, - gameId: String?
