Jetpack Compose的全屏Dialog实现

觉得如果是全屏的Dialog,可以直接使用Box在上面覆盖一层,比dialog更好整

不过硬是要整的话,就使用下面的扩展方法吧

import androidx.compose.ui.platform.LocalView
import androidx.compose.ui.window.DialogWindowProvider
import androidx.core.view.WindowCompat
import androidx.core.view.WindowInsetsCompat
import androidx.core.view.WindowInsetsControllerCompat
import android.view.View
import android.view.ViewGroup
import android.view.WindowManager

@Composable
fun HideSystemAndNavBarForDialog() {
    val view = LocalView.current
    LaunchedEffect(Unit) {
        val window = (view.parent as DialogWindowProvider).window

        WindowCompat.setDecorFitsSystemWindows(window, false)
        window.setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT)
        window.addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
        window.statusBarColor = android.graphics.Color.TRANSPARENT
        window.navigationBarColor = android.graphics.Color.TRANSPARENT
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            window.isNavigationBarContrastEnforced = false
        }
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
            window.attributes.layoutInDisplayCutoutMode =
                WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES
        }

        // 同时隐藏状态栏和导航栏（Compat，适配性更好）
        WindowCompat.getInsetsController(window, window.decorView)?.apply {
            systemBarsBehavior = WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
            hide(WindowInsetsCompat.Type.systemBars()) // 等同于 statusBars() | navigationBars()
        }

        // 旧版兜底（部分三星机型需要）
        @Suppress("DEPRECATION")
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.R) {
            window.decorView.systemUiVisibility =
                View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY or
                        View.SYSTEM_UI_FLAG_LAYOUT_STABLE or
                        View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or
                        View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION or
                        View.SYSTEM_UI_FLAG_FULLSCREEN or
                        View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
        }
    }
}

使用示例:

Dialog(onDismissRequest = {
        //禁止点击空白处关闭
    }, properties = DialogProperties(
        usePlatformDefaultWidth = false,
        decorFitsSystemWindows = false
    )) {
        HideSystemAndNavBarForDialog()
			
		DialogContent()
	}
)
