android gallery app with sliding pictures

As in the title. I want to have grid of pictures which consists of 2 columns and every picture must have the same dimensions. The user should be able to click on each picture to enter the full screen mode and then slide pictures from left to right (full sized pictures in that mode). By far, I made a grid of clickable elements but without functionality of sliding them. Here is my code:
activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.miki.androidtwo.MainActivity">
<GridView
android:id="#+id/grid"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:numColumns="2"
android:scrollbars="vertical"
android:gravity="center">
</GridView>
</RelativeLayout>
activity_full_image.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="0dp"
android:paddingLeft="0dp"
android:paddingRight="0dp"
android:paddingTop="0dp"
tools:context="com.example.miki.androidtwo.FullImageActivity">
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />
<Button
android:id="#+id/button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="I want to see other doggos" />
</RelativeLayout>
MainActivity.java
public class MainActivity extends AppCompatActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
GridView gridView = (GridView) findViewById(R.id.grid);
// Instance of ImageAdapter Class
gridView.setAdapter(new ImageAdapter(this));
/**
* On Click event for Single Gridview Item
* */
gridView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
// Sending image id to FullScreenActivity
Intent i = new Intent(getApplicationContext(), FullImageActivity.class);
// passing array index
i.putExtra("id", position);
startActivity(i);
}
});
}
}
Other classes are FullImageActivity and ImageAdapter; they are pretty obvious and simple so I won't post them.
How can I implement this sliding pictures functionality?
How can i determine dimensions of pictures in a grid that will be independent of the device?
Actually I think I hard-coded it with the line:
imageView.setLayoutParams(new GridView.LayoutParams(480,402));

If you want to slide the images while they are not full screen, you can use a HorizontalScrollView, or if you want to slide them while they are fullscreen, you can use a ViewPager, along with a PagerAdapter.
So to populate the grid imageView.setLayoutParams is fine to use for setting the size of each imageview like the way you did. When a user clicks on an image, you are going to go to a new Activity that is setup with a ViewPager and a PagerAdapter. This way the user can slide through fullscreen images.

Using BottomBar prevents fragments from opening?

I am using the Support Library to add a bottom bar similar to the material design one. The bottom bar works great but it seems that if I have the bar displayed, if I try to open any fragment from my custom adapter, the fragment does not open...or maybe it opens behind my main layout? I have no idea how to figure this out. Below is my code.
I've read more posts on SO and around the web and I think this is related to the fragment being properly loaded but below or next to the bottom bar...and that is why it isn't visible? Why does this happen? Is it because the bottom bar has a LinearLayout? I defined it as a menu so I'm not sure if I can control it being a LinearLayout....
Setting up the bottom bar, this method is called from the onCreate of my activity:
public void setupBottomToolbar(Bundle savedInstanceState) {
mBottomBar = BottomBar.attach(MainActivity.this, savedInstanceState);
mBottomBar.setItems(R.menu.bottombar_menu);
mBottomBar.setOnMenuTabClickListener(new OnMenuTabClickListener() {
#Override
public void onMenuTabSelected(#IdRes int menuItemId) {
if (menuItemId == R.id.toolbar_jobs) {
} else if (menuItemId == R.id.toolbar_messages) {
} else if (menuItemId == R.id.toolbar_recentJobs) {
} else if (menuItemId == R.id.toolbar_employerPools) {
}
}
#Override
public void onMenuTabReSelected(#IdRes int menuItemId) {
if (menuItemId == R.id.toolbar_jobs) {
// The user reselected item number one, scroll your content to top.
} else if (menuItemId == R.id.toolbar_messages) {
} else if (menuItemId == R.id.toolbar_employerPools) {
} else if (menuItemId == R.id.toolbar_recentJobs) {
}
}
});
// Setting colors for different tabs when there's more than three of them.
// You can set colors for tabs in three different ways as shown below.
mBottomBar.getBar().setBackgroundColor(getResources().getColor(R.color.laborswipe_darkgray));
mBottomBar.setActiveTabColor(getResources().getColor(R.color.laborswipe_lightgray));
// Make a Badge for the second tab, with red background color and a value of "13".
BottomBarBadge unreadMessages = mBottomBar.makeBadgeForTabAt(1, getResources().getColor(R.color.laborswipe_orange), 5);
// Control the badge's visibility
unreadMessages.show();
//unreadMessages.hide();
// Change the displayed count for this badge.
//unreadMessages.setCount(4);
// Change the show / hide animation duration.
unreadMessages.setAnimationDuration(200);
// If you want the badge be shown always after unselecting the tab that contains it.
unreadMessages.setAutoShowAfterUnSelection(true);
// If you don't want this badge to be hidden after selecting the tab contains it.
unreadMessages.setAutoShowAfterUnSelection(false);
}
In my adapter, I am trying to open the fragment when you click a button, like this:
holder.desc.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(context, "Open Description", Toast.LENGTH_SHORT).show();
JobDescFragment firstFragment = new JobDescFragment();
((MainActivity)context).getSupportFragmentManager().beginTransaction()
.add(R.id.fragment_container, firstFragment).commit();
}
});
If I comment out the call to setupBottomToolbar() in my onCreate of the activity, the fragment opens up fine...but that means I don't have the bottom bar...
What am I missing? There has to be a way to use the bottom bar and also open a fragment?
Thanks!
EDIT:
Here is the top part of my activity.

When I use the bottom bar (not working- no fragment opened but toast displayed):
When I don't use the bottom bar (workin-fragment opened, background is green):

try to link a pic of problem and without problem(no bottombar) and since you are using merge the layout hierarchy will be laid off according to your activity's viewgroup(linear,relative) constraints(we don't know what they are like).
as you said when there is no bottombar ,you fragment displays perfectly though when the bottombar it there ,problem stats ,as per your log in fragment indicating that your fragment is loading perfectly even though when bottombar is visible mean fragment is there but is not visible ,seems like your fragment didn't get the appropriate space to get displayed.
other solution can be adding bottom bar to your fragment instead of activity to avoid any overlapping ,like
mBottomBar.attach(findViewById(R.id.fragmentContainer), savedInstanceState);

OK, I think the solution for this should be simple, from what I can see in your code, you are attaching the BottomBar to your activity, I think this is the problem. If you were to read the readme.md in the roughike/BottomBar github page you'd find this
Why is it overlapping my Navigation Drawer?
All you need to do is instead of attaching the BottomBar to your Activity, attach it to the view that has your content. For example, if your fragments are in a ViewGroup that has the id fragmentContainer, you would do something like this:
mBottomBar.attach(findViewById(R.id.fragmentContainer), savedInstanceState);
So, since navigation drawer works with transition a fragment in and out of view with animation, the same thing is happening when you are adding a new fragment to your activity.
The Solution
From what I can see in your code, your fragment container id is this: fragment_container in your activity layout. So according to the documentation you'd just need to do attach your bottomBar to the fragment_container instead of MainActivity.this
mBottomBar.attach(findViewById(R.id.fragment_container), savedInstanceState);
If the above doesn't work try this
What you'd need to do is add an extra FrameLayout to hold your bottombar, which has a transparent background, but is on top of your fragment.
So change your main_activity layout to
<merge
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools">
<com.lorentzos.flingswipe.SwipeFlingAdapterView
android:id="#+id/frame"
android:background="#color/laborswipe_lightgray"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
tools:context=".MainActivity"
android:layout_gravity="top" />
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<FrameLayout
android:id="#+id/holder_bottombar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/transparent"/>
</merge>
Now in the code instead of attaching the bottom bar to mainactivity, just attach it to the holder like so
mBottomBar.attach(findViewById(R.id.holder_bottombar), savedInstanceState);

Show activity's view overlay FrameLayout with Fragment

I have the following activity:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="es.xxx.xxx.MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:background="#CCFF0000"
android:id="#+id/lyNetworkError">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="No hay conexión a internet"
android:textAlignment="center"/>
</LinearLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/container"/>
</RelativeLayout>
In its FrameLayout the app will load other fragments.
This is the onCreate code of activity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Constants.setAppContext(this);
setContentView(R.layout.activity_main);
Log.d("LoadFragment", "1 "+ loadFragment);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().replace(R.id.container, new MainFragment()).commit();
}
IntentFilter filter = new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION);
registerReceiver(networkStateReceiver, filter);
fragmentManager = getSupportFragmentManager();
lyNetworkError = (LinearLayout) findViewById(R.id.lyNetworkError);
}
The problem is that LinearLayout (That contains TextView) doesn't show (is posible that fragment render over LinearLayout, because if I remove getSupportFragmentManager().beginTransaction().replace(R.id.container, new MainFragment()).commit(); the LinearLayout appears)
So, how can I show the LinarLayout over fragment (loaded inside FrameLayout)?

If the LinearLayout and your Fragments are displaying in the correct location on screen when each is shown individually, then you can simply reverse the order of of the FrameLayout and LinearLayout in your XML.
The problem is that RelativeLayout allows its children to overlap. The last item in the RelativeLayout will appear "above" or "on top" of other items in the layout. Since you haven't specified any layout constraints for your views, the RelativeLayout puts them both in the default position, which is the top left corner. Since your FrameLayout is set to fill the parent view's width and height, it will overlay everything else.
If you actually want the LinearLayout to appear above the FrameLayout, then you can use RelativeLayout's positioning properties (explained very well here) to position your views.
Specifically, you would be looking for something like this:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#id/lyNetworkError"
android:id="#+id/container"/>
The android:layout_below attribute tells the FrameLayout that you want it to always be below the view with ID lyNetworkError (below as with text on a piece of paper, not in 3-dimensional space).

Android: findViewById is returning null?

In my main activity I'm trying to access a LinearLayout I have within my main ScrollView. My ScrollView is implemented as follows:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:id="#+id/graph"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="250dip"
/>
</ScrollView>
In my Main activity I inflate the scrollView and then try to access the linear layout as follows:
LayoutInflater inflater;
inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
ScrollView mainLayout = (ScrollView) inflater.inflate(R.layout.scrollview,
null);
LinearLayout layout = (LinearLayout) findViewById(R.id.graph);
Why would my findViewById be returning null here? I thought at first it was trying to find it before it had finished inflating, but I've tried having a while loop to wait for it to finish inflating, and this doesn't help either.

you have to give it the inflated layout
LinearLayout layout = (LinearLayout) mainLayout.findViewById(R.id.graph);

You can double check if specify the wrong layout in inflater.inflate() first.

How to Increase the size of Image View in Android

I am working on a project that requires me to implement two horizontal scroll views with an image view in between them. I would like to extend the size of the image view to fill up the gap in between the scroll view. I went through the sample code, but it doesn't seem to mention anywhere in the size of the image view. I've enclosed the code below after the Image describing my problem.
public class Gallery2DemoActivity extends Activity {
private Gallery gallery,gallery1;
private ImageView imgView;
private Integer[] Imgid = {
R.drawable.a_1, R.drawable.a_2, R.drawable.a_3, R.drawable.a_4, R.drawable.a_5, R.drawable.a_6, R.drawable.a_7
};
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
gallery = (Gallery) findViewById(R.id.examplegallery);
gallery.setAdapter(new AddImgAdp(this));
gallery1 = (Gallery)findViewById(R.id.examplegallery1);
gallery1.setAdapter(new AddImgAdp(this));
imgView = (ImageView)findViewById(R.id.ImageView01);
imgView.setImageResource(Imgid[0]);
gallery.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position, long id) {
imgView.setImageResource(Imgid[position]);
}
});
}
public class AddImgAdp extends BaseAdapter {
int GalItemBg;
private Context cont;
public AddImgAdp(Context c) {
cont = c;
TypedArray typArray = obtainStyledAttributes(R.styleable.GalleryTheme);
GalItemBg = typArray.getResourceId(R.styleable.GalleryTheme_android_galleryItemBackground, 0);
typArray.recycle();
}
public int getCount() {
return Imgid.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imgView = new ImageView(cont);
imgView.setImageResource(Imgid[position]);
imgView.setLayoutParams(new Gallery.LayoutParams(110, 100));
imgView.setScaleType(ImageView.ScaleType.FIT_XY);
imgView.setBackgroundResource(GalItemBg);
return imgView;
}
}
This is my XML main file.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"

<Gallery
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/examplegallery1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
Below is my Attributes file:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="GalleryTheme">
<attr name="android:galleryItemBackground" />
</declare-styleable>
</resources>

Vinner,
The issue here is really two issues:
The size of the ImageView is based on the parent, which means that it shares its width and height.
The Image is resized to match the most limiting dimension (width).
The easiest way to handle this is to set the ScaleType of the ImageView. There are a number of Scaling Types, but the one you probably want is Center Crop. In code, this is done by view_name.setScaleType(ImageView.ScaleType.CENTER_CROP). You may also do this in XML for your ImageView with the attribute android:scaleType="centerCrop". Mind you, this will resize your Image and maintain your aspect ratio, but it will cut off the sides.
Just add the above attribute to your ImageView in your XML, (probably under your layout_weight), and it should do what you want.
Hope this helps,
FuzzicalLogic

will you try below code... ?
?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Gallery
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/examplegallery"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_weight="1" />
<ImageView
android:id="#+id/ImageView01"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:src="#drawable/ic_launcher"
android:layout_weight="1"/>
<Gallery
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/examplegallery1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_weight="1"/>
</LinearLayout>
and if it do not work, try setting your gallery height to some dp, it will work.. Thanks

The size of the ImageView is based on the parent, which means that it shares its width and height. Also, the Image is resized to match the most limiting dimension (width).

It looks like in the AddImgAdp class, you set the ImageView's height and width to specific pixel sizes.
imgView.setLayoutParams(new Gallery.LayoutParams(110, 100)); //width = "110px", height="100px"
I personally would put the layout as a RelativeLayout, align the first gallery with the top, the second gallery with the bottom, nd have the ImageView set to align above the second gallery. Then make the image:
imgView.setLayoutParams( new Gallery.LayoutParams(
Gallery.LayoutParams.FILL_PARENT,
Gallery.LayoutParams.FILL_PARENT) );
If you set the ImageView to fill_parent with a LinearLayout, it will fill to the bottom of the screen and the second gallery will be off the screen.
Also know that by filling in all the space you will most likely distort the picture. Consider all of your resizing options: http://developer.android.com/reference/android/widget/ImageView.ScaleType.html
