如何在活动发布时显示“滑动菜单”？

Question

我正在尝试使用Jeremy Feinstein的优秀图书馆Sliding Menu。

对于我的情况，如果在滑动菜单打开的情况下启动活动将会很棒，如

而不是像

那样关闭滑动菜单

我试图将toggle()放入活动但没有用。

SlidingSherlockFragmentActivity

它与SlidingFragmentActivity相同，只是它扩展了SherlockFragmentActivity而不是FragmentActivity。

BaseActivity

public class BaseActivity extends SlidingSherlockFragmentActivity {
    private int mTitleRes;
    protected ListFragment mFrag;

    public BaseActivity(int titleRes) {
        mTitleRes = titleRes;
    }

    private static final String TAG = "BaseActivity";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setTitle(mTitleRes);

        // set the Behind View
        setBehindContentView(R.layout.menu_frame);
        FragmentTransaction t = this.getSupportFragmentManager().beginTransaction();
        mFrag = new SampleListFragment();
        t.replace(R.id.menu_frame, mFrag);
        t.commit();

        // customize the SlidingMenu
        SlidingMenu sm = getSlidingMenu();
        sm.setShadowWidthRes(R.dimen.shadow_width);
        sm.setShadowDrawable(R.drawable.shadow);
        sm.setBehindOffsetRes(R.dimen.slidingmenu_offset);
        sm.setFadeDegree(0.35f);
        sm.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        sm.setOnOpenListener(new SlidingMenu.OnOpenListener() {
            @Override
            public void onOpen() {
                Log.d(TAG, "onOpen");
            }
        });
        sm.setOnOpenedListener(new SlidingMenu.OnOpenedListener() {
            @Override
            public void onOpened() {
                Log.d(TAG, "onOpened");
            }
        });
        sm.setOnCloseListener(new SlidingMenu.OnCloseListener() {
            @Override
            public void onClose() {
                Log.d(TAG, "onClose");
            }
        });
        sm.setOnClosedListener(new SlidingMenu.OnClosedListener() {
            @Override
            public void onClosed() {
                Log.d(TAG, "onClosed");
            }
        });



    }


    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                toggle();
                return true;

        }
        return super.onOptionsItemSelected(item);
    }

}

FlipperCheck

public class FlipperCheck extends BaseActivity {

    private ViewFlipper flipper;
    private TextView secondaryText;

    public FlipperCheck() {
        super(R.string.app_name);
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setSlidingActionBarEnabled(true);


        setContentView(R.layout.main);
        flipper = (ViewFlipper) findViewById(R.id.voicerecorder_textflipper);
        flipper.startFlipping();
        flipper.setInAnimation(AnimationUtils
                .loadAnimation(getApplicationContext(), android.R.anim.fade_in));
        flipper.setOutAnimation(AnimationUtils
                .loadAnimation(getApplicationContext(), android.R.anim.fade_out));

        secondaryText = (TextView) findViewById(R.id.voicerecorder_secondarytext);
        secondaryText.setText("Why cannot I see u...");

        final TextView firstText = (TextView) findViewById(R.id.firsttext);

        final TextView secondText = (TextView) findViewById(R.id.secondtext);


        Button button = (Button) findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                stopFlipper();
                flipper.setVisibility(View.INVISIBLE);
                secondaryText.setVisibility(View.VISIBLE);
            }
        });

        Button secondButton = (Button) findViewById(R.id.second_button);
        secondButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                firstText.setText("Replaying");
                secondText.setText("Replaying");

            }
        });
    }

    @Override
    protected void onStart() {
        super.onStart();
        toggle();
    }


    private void stopFlipper() {
        flipper.getInAnimation().setAnimationListener(new Animation.AnimationListener() {

            public void onAnimationStart(Animation animation) {
            }

            public void onAnimationRepeat(Animation animation) {
            }

            public void onAnimationEnd(Animation animation) {

                int displayedChild = flipper.getDisplayedChild();
                int childCount = flipper.getChildCount();

                if (displayedChild == childCount - 1) {
                    flipper.stopFlipping();
                }
            }
        });
    }


}

[编辑2]

toggle()中的onStart()似乎是在显示活动之前激活滑动菜单的打开和关闭。

我的问题

使用Android库“滑动菜单”时如何使用滑动菜单打开活动？

Answer 1

您可以使用：

@Override
public void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            toggle();
        }
    }, 1000);
}

Answer 2

如果您从Handler类之一继承，那么如果没有自己发布到SlidingActivity，有更好的方法可以做到这一点：

@Override
public void onPostCreate(Bundle savedInstanceState) {
    if (savedInstanceState == null) {
        savedInstanceState = new Bundle();
        savedInstanceState.putBoolean("SlidingActivityHelper.open", true);
    }
    super.onPostCreate(savedInstanceState);
}

这是有效的，因为SlidingActivityHelper从保存的实例状态恢复菜单打开/关闭状态。如果没有保存状态，那么将其自己设置为默认状态没有任何害处。

Answer 3

getSlidingMenu().post(new Runnable() {

        @Override
        public void run() {

           getSlidingMenu().showMenu();

        }
    });

把它放在onCreate为我做了诀窍。
