如何在活动启动时显示“滑动菜单”？
如何在活动启动时显示“滑动菜单”？
提问于 2012-12-31 01:35:00
我正在尝试使用杰里米·范斯坦的优秀的库Sliding Menu。
对于我的情况，如果活动是在滑动菜单打开的情况下启动的，那就太好了，比如
而不是像这样关闭滑动菜单
我已经尝试将toggle()放在活动中，但是没有用。
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();
}
}
});
}

看起来像onStart()中的toggle()在活动显示之前打开和关闭滑动菜单都是激活的。

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);

如果你继承了一个SlidingActivity类，有一种更好的方法可以不用自己发送到Handler：
@Override
public void onPostCreate(Bundle savedInstanceState) {
if (savedInstanceState == null) {
savedInstanceState = new Bundle();
savedInstanceState.putBoolean("SlidingActivityHelper.open", true);
}
super.onPostCreate(savedInstanceState);
}这之所以有效，是因为SlidingActivityHelper从保存的实例状态恢复菜单打开/关闭状态。如果没有保存的状态，那么将其设置为默认状态也没有什么坏处。

getSlidingMenu().post(new Runnable() {
@Override
public void run() {
getSlidingMenu().showMenu();
}
});把它放在onCreate里帮了我大忙。
