android - 在 Android 5.0 Lollipop 上首次切换滑动菜单后 UI 未刷新

Question

我有一个 ResponsiveUIActivity，它扩展了 SlidingFragmentActivity。我的应用程序在 android 5.0 版本以下完美运行。但是当我第一次切换滑动菜单时，我的用户界面没有刷新并且不可点击。例如，在第一次切换后，我无法滚动 ListView 或在 EditText 上写东西。如果我切换滑动菜单，UI 会刷新，我可以看到更改。我该如何解决这个问题？

ResponsiveUIActivity.java

public class ResponsiveUIActivity extends SlidingFragmentActivity {
    private Fragment mContent;
    public static ResponsiveUIActivity rootActivity;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setTitle(R.string.responsive_ui);
        setContentView(R.layout.responsive_content_frame);
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        rootActivity = this;

        // startNotificationService();

        // check if the content frame contains the menu frame
        if (findViewById(R.id.menu_frame) == null) {
            setBehindContentView(R.layout.menu_frame);
            getSlidingMenu().setSlidingEnabled(true);
            getSlidingMenu().setTouchModeAbove(SlidingMenu.TOUCHMODE_MARGIN);

            // show home as up so we can toggle
            getActionBar().setDisplayHomeAsUpEnabled(false);
            getActionBar().setDisplayShowHomeEnabled(false);
        } else {
            // add a dummy view
            View v = new View(this);
            setBehindContentView(v);
            getSlidingMenu().setSlidingEnabled(false);
            getSlidingMenu().setTouchModeAbove(SlidingMenu.TOUCHMODE_NONE);
        }

        // set the Above View Fragment
        if (savedInstanceState != null)
            mContent = getSupportFragmentManager().getFragment(
                    savedInstanceState, "mContent");
        if (mContent == null)
            mContent = new NewsFragment();

        // customize the SlidingMenu
        SlidingMenu sm = getSlidingMenu();
        sm.setBehindOffsetRes(R.dimen.slidingmenu_offset);

        sm.setShadowDrawable(R.drawable.shadow);
        sm.setBehindScrollScale(0.25f);
        sm.setFadeDegree(0.25f);

                Log.d("ToggleMenu", "onOpened");
            }
        });

            public void onClose() {
                Log.d("ToggleMenu", "onClose");
            }
        });

        getSupportFragmentManager().beginTransaction()

我遇到了同样的问题，但我已经设法解决了这个问题。实际问题在于硬件加速方面的缺陷，因此如果您将 AndroidManifest 放入您的应用程序hardwareAccelerated="true"您的问题将得到解决。
