AppCompatDelegate

Kotlin |Java

abstract class AppCompatDelegate

kotlin.Any
↳	androidx.appcompat.app.AppCompatDelegate

This class represents a delegate which you can use to extend AppCompat's support to any android.app.Activity.

When using an AppCompatDelegate, you should call the following methods instead of the android.app.Activity method of the same name:

addContentView(android.view.View, android.view.ViewGroup.LayoutParams)
setContentView(int)
setContentView(android.view.View)
setContentView(android.view.View, android.view.ViewGroup.LayoutParams)
requestWindowFeature(int)
hasWindowFeature(int)
invalidateOptionsMenu()
startSupportActionMode(androidx.appcompat.view.ActionMode.Callback)
setSupportActionBar(androidx.appcompat.widget.Toolbar)
getSupportActionBar()
getMenuInflater()
findViewById(int)

The following methods should be called from the android.app.Activity method of the same name:

onCreate(android.os.Bundle)
onPostCreate(android.os.Bundle)
onConfigurationChanged(android.content.res.Configuration)
onStart()
onStop()
onPostResume()
onSaveInstanceState(Bundle)
setTitle(CharSequence)
onStop()
onDestroy()

An Activity can only be linked with one AppCompatDelegate instance, therefore the instance returned from create(Activity, AppCompatCallback) should be retained until the Activity is destroyed.

Summary

Constants
static Int	`FEATURE_ACTION_MODE_OVERLAY` Flag for specifying the behavior of action modes when an Action Bar is not present.
static Int	`FEATURE_SUPPORT_ACTION_BAR` Flag for enabling the support Action Bar.
static Int	`FEATURE_SUPPORT_ACTION_BAR_OVERLAY` Flag for requesting an support Action Bar that overlays window content.
static Int	`MODE_NIGHT_AUTO`
static Int	`MODE_NIGHT_AUTO_BATTERY` Night mode which uses a dark mode when the system's 'Battery Saver' feature is enabled, otherwise it uses a 'light mode'.
static Int	`MODE_NIGHT_AUTO_TIME` Night mode which switches between dark and light mode depending on the time of day (dark at night, light in the day).
static Int	`MODE_NIGHT_FOLLOW_SYSTEM` Mode which uses the system's night mode setting to determine if it is night or not.
static Int	`MODE_NIGHT_NO` Night mode which uses always uses a light mode, enabling `notnight` qualified resources regardless of the time.
static Int	`MODE_NIGHT_UNSPECIFIED` An unspecified mode for night mode.
static Int	`MODE_NIGHT_YES` Night mode which uses always uses a dark mode, enabling `night` qualified resources regardless of the time.

Public methods
abstract Unit	`addContentView(v: View!, lp: LayoutParams!)` Should be called instead of `Activity#addContentView(android.view.View, android.view.ViewGroup.LayoutParams)`}
abstract Boolean	`applyDayNight()` Applies the currently selected night mode to this delegate's host component.
open Unit	`attachBaseContext(context: Context!)`
open Context	`attachBaseContext2(@NonNull context: Context)` Should be called from Activity#attachBaseContext(Context).
open static AppCompatDelegate	`create(@NonNull activity: Activity, @Nullable callback: AppCompatCallback?)` Create an `androidx.appcompat.app.AppCompatDelegate` to use with `activity`.
open static AppCompatDelegate	`create(@NonNull dialog: Dialog, @Nullable callback: AppCompatCallback?)` Create an `androidx.appcompat.app.AppCompatDelegate` to use with `dialog`.
open static AppCompatDelegate	`create(@NonNull context: Context, @NonNull window: Window, @Nullable callback: AppCompatCallback?)` Create an `androidx.appcompat.app.AppCompatDelegate` to use with a `context` and a `window`.
open static AppCompatDelegate	`create(@NonNull context: Context, @NonNull activity: Activity, @Nullable callback: AppCompatCallback?)` Create an `androidx.appcompat.app.AppCompatDelegate` to use with a `context` and hosted by an `Activity`.
abstract View!	`createView(@Nullable parent: View?, name: String!, @NonNull context: Context, @NonNull attrs: AttributeSet)` This should be called from a `LayoutInflater.Factory2` in order to return tint-aware widgets.
abstract T?	`findViewById(@IdRes id: Int)` Finds a view that was identified by the id attribute from the XML that was processed in `onCreate`.
open static Int	`getDefaultNightMode()` Returns the default night mode.
