How to show "Sliding Menu" on Activity launch?

Question

I am trying to use excellent library Sliding Menu by Jeremy Feinstein.

For my case it will be great if the activity is launched with Sliding Menu open like

instead of Sliding menu closed like

I have tried to put toggle() in the activity but no use.

SlidingSherlockFragmentActivity

It is same as SlidingFragmentActivity except it extends SherlockFragmentActivity instead of 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();
                }
            }
        });
    }


}

[Edit 2]

Look like toggle() in onStart() is activation both opening and closing of Sliding Menu before activity is displayed.

My Question

While using Android Library "Sliding Menu" how to launch an activity with Sliding Menu open?

Answer 1

You can use:

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

Answer 2

There's a better way to do this without posting to the Handler yourself, if you inherit from one of the SlidingActivity classes:

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

This works because SlidingActivityHelper restores the menu open/closed state from the saved instance state. If there's no saved state then there's no harm in setting it yourself as a default state.

Answer 3

getSlidingMenu().post(new Runnable() {

        @Override
        public void run() {

           getSlidingMenu().showMenu();

        }
    });

Put it in onCreate did the trick for me.
