我如何使一个活动全屏?没有通知栏。
当前回答
在Android 10上,没有一款适合我。
但我工作得很好(oncreate的第一行):
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_IMMERSIVE;
decorView.setSystemUiVisibility(uiOptions);
setContentView(....);
if (getSupportActionBar() != null) {
getSupportActionBar().hide();
}
享受:)

对于安卓X
1. 透明状态栏
window?.decorView?.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN)
window.statusBarColor = Color.TRANSPARENT
2. 透明的状态栏和底部导航栏
window.setFlags(
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
);
3.隐藏状态栏
API 30+推荐的Compat解决方案(包括向后兼容性)
val windowInsetsController =
WindowCompat.getInsetsController(window, window.decorView) ?: return
windowInsetsController.systemBarsBehavior =
WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
windowInsetsController.hide(WindowInsetsCompat.Type.statusBars())

4. 隐藏状态栏和底部导航栏
消防级别30:
SystemUiVisibility标志已弃用。请改用WindowInsetsController。
和3一样。,只需使用WindowInsetsCompat.Type.systemBars()
val actionBar: ActionBar? = supportActionBar
if (actionBar != null) actionBar.hide()
val windowInsetsController =
WindowCompat.getInsetsController(window, window.decorView) ?: return
windowInsetsController.systemBarsBehavior =
WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
windowInsetsController.hide(WindowInsetsCompat.Type.systemBars())
https://developer.android.com/training/system-ui/immersive
把这些代码放在哪里?
override fun onCreate(savedInstanceState: Bundle?) {
/* Put above code here ..... */
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_slider)
}
Note
我在Pixel 3A模拟器中检查了这段代码 可能自定义android操作系统不支持 set style <style name="主题。"全屏Theme.MaterialComponents.DayNight.NoActionBar“父= >
你可以通过编程来实现:
public class ActivityName extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// remove title
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
}
}
或者你也可以通过AndroidManifest.xml文件来实现:
<activity android:name=".ActivityName"
android:label="@string/app_name"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"/>
编辑:
如果你正在使用AppCompatActivity,那么你需要添加新的主题
<style name="Theme.AppCompat.Light.NoActionBar.FullScreen" parent="@style/Theme.AppCompat.Light.NoActionBar">
<item name="android:windowNoTitle">true</item>
<item name="android:windowActionBar">false</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">@null</item>
</style>
然后使用它。
<activity android:name=".ActivityName"
android:label="@string/app_name"
android:theme="@style/Theme.AppCompat.Light.NoActionBar.FullScreen"/>

@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
adjustFullScreen(newConfig);
}
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus) {
adjustFullScreen(getResources().getConfiguration());
}
}
private void adjustFullScreen(Configuration config) {
final View decorView = getWindow().getDecorView();
if (config.orientation == Configuration.ORIENTATION_LANDSCAPE) {
decorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
} else {
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
}
}
protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_splash_screen);
getSupportActionBar().hide();
}
根据安卓开发者培训
你应该做到以下几点:
科特林:
private fun hideSystemBars() {
val windowInsetsController =
ViewCompat.getWindowInsetsController(window.decorView) ?: return
// Configure the behavior of the hidden system bars
windowInsetsController.systemBarsBehavior =
WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
// Hide both the status bar and the navigation bar
windowInsetsController.hide(WindowInsetsCompat.Type.systemBars())
}
Java:
private void hideSystemBars() {
WindowInsetsControllerCompat windowInsetsController =
ViewCompat.getWindowInsetsController(getWindow().getDecorView());
if (windowInsetsController == null) {
return;
}
// Configure the behavior of the hidden system bars
windowInsetsController.setSystemBarsBehavior(
WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
);
// Hide both the status bar and the navigation bar
windowInsetsController.hide(WindowInsetsCompat.Type.systemBars());
}
