Android为FLAG_TRANSLUCENT禁用ActionBar和NavigationBar的叠加层

Question

正如您在图片中看到的那样，导航栏和状态栏覆盖了布局。我所做的只是

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        Window w = getWindow();
        w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
        w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); w.setFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN,WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);

    }

我尝试通过执行以下操作来禁用叠加层：

w.clearFlags(View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
        w.clearFlags(View.SYSTEM_UI_FLAG_FULLSCREEN);
        w.setFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN,WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);

但没有成功。 1up

可以获得帮助

谢谢

您使用的是自定义主题吗？这样的设置android:windowActionBarOverlay为真？

如果是，请在主题中禁用它。

我相信您正试图将您的应用程序置于沉浸式模式中。如果是这样，这是我从Google找到的代码，它会将您的应用置于沉浸式模式，触摸时会显示状态栏和导航栏。

public class ImmersiveActivity extends Activity {
    private static final int INITIAL_HIDE_DELAY = 300;

    private View mDecorView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.immersive_activity);

        final View controlsView = findViewById(R.id.fullscreen_content_controls);
        final View contentView = findViewById(R.id.fullscreen_content);

        mDecorView = getWindow().getDecorView();
        mDecorView.setOnSystemUiVisibilityChangeListener(
                new View.OnSystemUiVisibilityChangeListener() {
                    @Override
                    public void onSystemUiVisibilityChange(int flags) {
                        boolean visible = (flags & View.SYSTEM_UI_FLAG_HIDE_NAVIGATION) == 0;
                        controlsView.animate()
                                .alpha(visible ? 1 : 0)
                                .translationY(visible ? 0 : controlsView.getHeight());
                    }
                });
        contentView.setClickable(true);
        final GestureDetector clickDetector = new GestureDetector(this,
                new GestureDetector.SimpleOnGestureListener() {
                    @Override
                    public boolean onSingleTapUp(MotionEvent e) {
                        boolean visible = (mDecorView.getSystemUiVisibility()
                                & View.SYSTEM_UI_FLAG_HIDE_NAVIGATION) == 0;
                        if (visible) {
                            hideSystemUI();
                        } else {
                            showSystemUI();
                        }
                        return true;
                    }
                });
        contentView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                return clickDetector.onTouchEvent(motionEvent);
            }
        });

        showSystemUI();
    }

    @Override
    public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);

        // When the window loses focus (e.g. the action overflow is shown),
        // cancel any pending hide action. When the window gains focus,
        // hide the system UI.
        if (hasFocus) {
            delayedHide(INITIAL_HIDE_DELAY);
        } else {
            mHideHandler.removeMessages(0);
        }
    }

    private void hideSystemUI() {
        mDecorView.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_LOW_PROFILE
                | View.SYSTEM_UI_FLAG_IMMERSIVE);
    }

    private void showSystemUI() {
        mDecorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
    }

    private final Handler mHideHandler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            hideSystemUI();
        }
    };

    private void delayedHide(int delayMillis) {
        mHideHandler.removeMessages(0);
        mHideHandler.sendEmptyMessageDelayed(0, delayMillis);
    }
}
