I am trying to create a horizontal LinearLayout which is wider than the screen of the device. It contains a Button which will move the layout to view the part outside the screen when it is clicked. The problem is that android is not creating the part outside the screen, so when I press the button, the view moves to show black screen where the remaining view should have been.
My code-
MainActivity.java
public class MainActivity extends BaseGameActivity implements OnClickListener {
private Context mContext;
private int mScreenHeight;
private int mScreenWidth;
private LinearLayout mViewContainer;
private View mTransparentContainer;
private Button mSliderBtn;
private View mSlidingView;
private View mHomeView;
private int mSlidingWidth;
private boolean mIsSlidingMenuVisible = false;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mContext = getApplicationContext();
mScreenHeight = UserScreen.getHeight(mContext);
mScreenWidth = UserScreen.getWidth(mContext);
mSlidingWidth = (int) (getResources().getDimension(R.dimen.sliding_menu_offset) + 0.5f);
mViewContainer = new LinearLayout(mContext);
mViewContainer.setOrientation(LinearLayout.HORIZONTAL);
mViewContainer.setLayoutParams(new LinearLayout.LayoutParams(mScreenWidth + mSlidingWidth, mScreenHeight));
setContentView(mViewContainer);
LinearLayout homeContainer = new LinearLayout(mContext);
LinearLayout.LayoutParams homeContainerParams = new LinearLayout.LayoutParams(mScreenWidth, LayoutParams.MATCH_PARENT);
mHomeView = getLayoutInflater().inflate(R.layout.activity_main, homeContainer);
mHomeView.setBackgroundColor(0x80ffffff);
mViewContainer.addView(homeContainer, homeContainerParams);
LinearLayout slidingContainer = new LinearLayout(mContext);
LinearLayout.LayoutParams slidingContainerParams = new LinearLayout.LayoutParams(mSlidingWidth, LayoutParams.MATCH_PARENT);
mSlidingView = getLayoutInflater().inflate(R.layout.slider_menu, slidingContainer);
mViewContainer.addView(slidingContainer, slidingContainerParams);
initUi();
// other code
}
public void initUi() {
mSliderBtn = (Button) mHomeView.findViewById(R.id.button_slider);
mSliderBtn.setOnClickListener(this);
mTransparentContainer = mHomeView.findViewById(R.id.transparent_container);
mTransparentContainer.setOnClickListener(this);
// other code
}
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.button_slider:
mSliderBtn.setEnabled(false);
mIsSlidingMenuVisible = true;
mTransparentContainer.setVisibility(View.VISIBLE);
mTransparentContainer.bringToFront();
tableMoveLeft(mViewContainer, mSlidingWidth);
break;
case R.id.transparent_container:
mSliderBtn.setEnabled(true);
mIsSlidingMenuVisible = false;
mTransparentContainer.setVisibility(View.GONE);
tableMoveRight(mViewContainer, mSlidingWidth);
break;
// other cases
}
}
// Animation Functions
public void tableMoveLeft(final View container, final float newPos){
ObjectAnimator moveLeft = ObjectAnimator.ofFloat(container, "translationX", 0, -newPos);
moveLeft.setDuration(300);

Using a ScrollView is not a solution because I dont want the user to freely scroll the view, and also there is a ViewPager in the main layout which will conflict with it. Please help. Thanks.
Android officially introduced sliding panel menu by introducing a newer concept called Navigation Drawer. Most of the time Sliding Menu (Navigation Drawer) will be hidden and can be shown by swiping the screen from left edge to right or tapping the app icon on the action bar.
For example, the following layout uses a DrawerLayout with two child views: a FrameLayout to contain the main content (populated by a Fragment at runtime), and a ListView for the navigation drawer.
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<ListView android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
for additional info about NavigationDrawer, please take a look into these links :
http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/
http://developer.android.com/training/implementing-navigation/nav-drawer.html
The problem was that the layout with size larger than screen size was set as the root container of the activity. I don't know what was the problem caused by that, but to fix it-
#Override
public void onCreate(Bundle savedInstanceState) {
super(savedInstanceState);
LinearLayout rootContainer = new LinearLayout(mContext);
setContentView(rootContainer);
// other code
rootContainer.addView(mViewContainer);
}
Any explanations of why having a root view larger than screen size created a problem are welcome :)

See FoldingCell for Android for more help.
In your build.gradle()
dependencies{
implementation 'com.ramotion.foldingcell:folding-cell:1.2.2'
}
In you XML layout
<com.ramotion.foldingcell.FoldingCell
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/folding_cell"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!--Layout One-->
<!--Layout Two-->
</com.ramotion.foldingcell.FoldingCell>
Almost done! Two steps remain! For correct animation, you need to set up two properties on the root element(s) of your Folding Cell:
android:clipChildren="false"
android:clipToPadding="false"
In your Java class
// get our folding cell
final FoldingCell fc = (FoldingCell) findViewById(R.id.folding_cell);
// attach click listener to folding cell
fc.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
fc.toggle(false);
}
});
I have created a DrawerLayout with a right side drawer. So far, so good. Now, there's one menu item which, when clicked opens a pop-out menu with 5 different options (see screenshot). When one of the options is clicked the icon in the main menu should get swapped for the icon that I just clicked and then the main menu should close. However, I have not been able to create that behaviour. Currently when I try to click one of the options in the pop-out menu the following happens:
1. The main menu (the drawer) closes.
2. Only if I click the desired option again the icon in the main menu gets swapped.
As far as I understand this it is the default behaviour of a drawer within a DrawerView to be closed as soon as I click somewhere in the screen. I have tried to work around it by setting the lock mode:
myDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_OPEN, Gravity.END)
... but no luck. The drawer closes as soon as I try to click one of the items in the pop-out.
Is it even possible to achieve what I want in a DrawerLayout?

Edit:
I found this post that offered me a simple way of preventing my pop-out from being closed by adding the following to my MainActivity.java:
#Override
public boolean dispatchTouchEvent(MotionEvent event) {
// We only want to intercept MotionEvent.ACTION_UP if the pop-out is present
return !(isColorModePanelOpen && event.getAction() == MotionEvent.ACTION_UP) && super.dispatchTouchEvent(event);
}
That worked in so far as the drawer is not being closed immediately when trying to click one of the buttons in the pop-out. Unfortunately, the buttons don't accept clicks (resp. touches with an event action MotionEvent.ACTION_DOWN) either. It seems, as long as the drawer isn't closed again, the whole screen is being blocked from any user interaction.
Can anyone confirm my suspicion? (or prove me wrong)
Thanks
Try this code in onResume() of your Activity
if(condition)
{
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_OPEN);
}
else
{
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
}
I have an Action Bar. It has two drawers coming from left and right.
For the left, I'm using the Action Bar Toggle button on the top left as shown in the image below. Can I put that toggle button in the right side too?
I can use a custom linear layout view (ImageView - EditText - ImageView) to add it to the getActionBar.setCustomView() method and implement click listeners on the imageview's to show drawers.
My question is, does android provide a right toggle button like the left?
You have to make some changes in your .xml file and Java code.
First Step
Let start with your .xml file.
Code
First FrameLayout: represent to action-bar, note we have ImageView called drawer_indicator and it's our right toggle.
Second FrameLayout: represent our fragment containers.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<!-- Action-bar looking view -->
<FrameLayout
android:layout_width="match_parent"
android:layout_height="#dimen/actionbar_dimen"
android:background="#color/blue" >
<ImageView
android:id="#+id/drawer_indicator"
android:layout_width="#dimen/actionbar_dimen"
android:layout_height="#dimen/actionbar_dimen"
android:layout_gravity="right"
android:background="#drawable/drawer_selector"
android:scaleType="centerInside" />
<TextView
android:id="#+id/indicator_style"
android:layout_width="wrap_content"
android:layout_height="#dimen/actionbar_dimen"
android:layout_gravity="center"
android:background="#drawable/drawer_selector"
android:gravity="center"
android:paddingLeft="12dp"
android:paddingRight="12dp"
android:text="#string/tests"
android:textColor="#android:color/white"
android:textStyle="bold" />
</FrameLayout>
<!-- Action-bar Ends -->
<!-- Drawer Layout -->
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" >
<!-- our Fragment Content-->
<FrameLayout
android:id="#+id/view_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/light_gray"
android:gravity="center" />
<!-- slide menu android:layout_gravity="end" to make it come from right-->
<LinearLayout
android:id="#+id/drawer_content"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="end"
android:background="#android:color/white"
android:gravity="center"
android:orientation="vertical" >
<!-- drawer list-->
<ListView
android:id="#+id/DrawerList"
android:layout_width="240dp"
android:layout_height="match_parent"
/>
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
Second Step

R.drawable.test));
// drawer adapter
DrawerAdapter adapter = new DrawerAdapter(this, Items);
// set adapter to our drawer list
DrawerList.setAdapter(adapter);
// attach listener to drawer list
DrawerList.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// handle select item here
}
});
// initialize our drawer layout
drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
// right toggle button
final ImageView imageView = (ImageView) findViewById(R.id.drawer_indicator);
final Resources resources = getResources();
// its custom class

imageView.setImageDrawable(drawerArrowDrawable);
drawer.setDrawerListener(new DrawerLayout.SimpleDrawerListener() {
#Override
public void onDrawerSlide(View drawerView, float slideOffset) {
offset = slideOffset;
// Sometimes slideOffset ends up so close to but not quite 1 or 0.
if (slideOffset >= .995) {
flipped = true;
drawerArrowDrawable.setFlip(flipped);
} else if (slideOffset <= .005) {
flipped = false;
drawerArrowDrawable.setFlip(flipped);
}
drawerArrowDrawable.setParameter(offset);
}
});
// attach listener to toggle image view
imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
openDrawer();
}
});
}
I hope it be clear to you.
I have a layout with a top bar container and a content container. When clicking on a button in the top bar, a vertical menu is displayed using an animation. My minSdkVersion is 9.
This works well when I start the app and I still haven't clicked a menu button (i.e. the content fragment has not changed), but as soon as I have clicked an option (and then replace the fragment in the content_container), the vertical menu behaves erratically. The click event of the menu btn is properly triggered, but the vertical menu is not always shown (but sometimes it is...). However, when I click the button and then touch the screen, the animation (show or hide the menu) starts.
I guess it has something to do with the vertical menu overlapping the content fragment, and then replacing the content fragment modify it in some way, but I can't find any solution.
Anybody can help?

At the end of my Toggle method, I invalidate the root view:
rootView.invalidate();
and now it works. Not quite clear why I must do that though...
I know there is already an accepted answer for this but I had a similar problem and the answer didnt help.
I had a view that I declared at the end of my layout to keep its Z index above its siblings. I had to touch the page to make the animation work.
So I set the Z index again through Java and it worked.
view.bringToFront();
So I'm trying my crack at the infamous slide out menu, like in G+ and Youtube.
In this cause I'm setting an ActionBar UP button that I want to use to open the Side Menu.
I have most everything laid out correctly, but my HorizontalScrollView is not sliding when I ask.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<include
android:layout_width="wrap_content"
layout="#layout/side_menu" />
<HorizontalScrollView
android:id="#+id/menu_scroll_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:scrollbars="horizontal" >
<include
layout="#layout/main_content" />
</HorizontalScrollView>
</FrameLayout>
private void toggleSideMenu() {
mMenuScrollView.postDelayed(new Runnable() {
#Override
public void run() {
int menuWidth = mSideMenu.getMeasuredWidth();
if (!mIsMenuVisible) {
// Scroll to 0 to reveal menu
int left = 0;
mScrollView.smoothScrollTo(left, 0);
} else {
// Scroll to menuWidth so menu isn't on screen.
int left = menuWidth;
mScrollView.smoothScrollTo(left, 0);
}
mIsMenuVisible = !mIsMenuVisible;
}
}, 50);
}
My call to smoothScroll doesn't seem to be working.
I tweaked the example some and ended up getting it working. Much more barebones than the other examples I have seen out there.
This works correctly, however I do not have a smooth animation for the MenuSliding. And I didn't need the HorizontalScrollView. As a side effect, users will have to hit the button to pop the menu in and out. This will not have the slide feature.
However, it is a BARE BONES example to get things rolling. Enjoy!
