TextView and ImageView not changing on click

TextView and ImageView not changing on click - android

I have an activity with three fragments placed in a ViewPager. On the first two fragments I have a list that drops down, kind of like an animated ExpandableListView but it is a simple RelativeLayout containing a TextView and ImageView, when pressed slides down a LinearLayout containing some elements. On clicking the RelativeLayout the followig actions are taken:
change the background color of the clicked RelativeLayout (works every time for every layout in every fragment)
change the color of the text in TextView (works every time for the first element I'll explain below)
animate the image, an arrow to change color and rotate (also works but for the first element)
The problem is as follows:
the first fragment contains only one list (a RelativeLayout that shows or hides a LinearLayout) and it works fine the background, text color and image change and the image rotates and the Linearlayout slides up and down correspondingly. The second fragment contains 4 such groupings (RelativeLayout controlling LinearLayout) and on the first time this fragment is shown only the first grouping seems to work. The other three change background and slide the Linearlayout but as far as i can tell it keeps the same color and the same image (there are two colors a white and an orange that change and since the background changes from orange to white i assume the text stays white instead of changing to orange, same goes for the image).
The punchline:
when I leave it for a few seconds and click it again it works fine, everything changes accordingly, and if i for instance flip to the third fragment and back to the second it works. On the other hand if I start the app, got to the second fragment, back to the first, and to the second again it doesn't work.
I don't know if this has something to do with the GC and recycling views or something else.

Update
Running a log on my fragment class that extends Fragment and on OnPageChangeListener's method onPageSelected() shows that tags are set properly and visible. The issue seems to be related to the lifecycle of fragments since the changes to the text and image only occur when I flip through ALL three fragments and then return to the second.
Setting the pager:
List<Fragment> fragments = getFragments();
pageAdapter = new NutritionPageAdapter(getSupportFragmentManager(),
fragments);
ViewPager pager = (ViewPager) findViewById(R.id.viewpager);
pager.setAdapter(pageAdapter);
getFragments()
private List<Fragment> getFragments() {
List<Fragment> fList = new ArrayList<Fragment>();
fList.add(NutritionFragment.newInstance("Menu"));
fList.add(NutritionFragment.newInstance("Nutrition"));
fList.add(NutritionFragment.newInstance("Transition"));
return fList;
}
My Fragment class
public static final String FRAGMENT_TITLE = "FRAGMENT_TITLE";
private View v;
public static final NutritionFragment newInstance(String string) {
NutritionFragment f = new NutritionFragment();
Bundle b = new Bundle(1);
b.putString(FRAGMENT_TITLE, string);
f.setArguments(b);
return f;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
String screen = getArguments().getString(FRAGMENT_TITLE);
if (screen.equals("Menu")) {
v = inflater.inflate(R.layout.nutrition_menu_activity_layout,
container, false);
} else if (screen.equals("Transition")) {
v = inflater.inflate(R.layout.nutrition_transition_activity_layout,
container, false);
} else {
v = inflater.inflate(R.layout.nutrition_nutrition_activity_layout,
container, false);

android studio zoom image in + horizontal scrolling

I am working on an android project, and for that I have a human model image:
I would like to zoom right in, so that you can only see one human model e.g. the middle one to start with, then have 2 arrows on either side of the image, and click left arrow to see the left human model, and right to see the right human model.
This is my attempt, but doesn't work

How to position an ImageView in the same place in different screen sizes?

I been working on a simple android app that calculates a person's Body Mass Index, I have all the features working but positioning the arrow in the right place in the color bar corresponding to the user's screen size is what Im stuck on. I have it working by setting the X and Y values of the arrow ImageView but obviously the place of the arrow changes when i test my application in different screen sizes even though im coverting a dp value to pixels. How can I position the arrow ImageView so that it stays the same in different screen sizes?

Add Linearlayout as subparent of childview,use its orientation and gravity attribute you can easily get the design in more optimize way and suitable for everyscreen size.
here i have used RelativeLayout as Parent and LinearLayout as sub-parent of childview.

GridView with incomplete row item does not scroll

I have a problem with my GridView when it receives incomplete row item number, it doesn't scroll anymore. My items are dynamic which are given by the server, I have 3 columns and if the number of GridView items are more than enough to enable scrolling and if the row item is 3, it works fine. For example (9 items):
But if the third row has only 1 or 2 item/s, it doesn't scroll anymore (7 or 8 items):
This has caused me headache more than excitement, my GridView in layout is:
<GridView
android:id="#+id/gridView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#color/white"
android:listSelector="#android:color/transparent"
android:numColumns="3"
android:stretchMode="columnWidth" >
</GridView>
In my activity nothing much, just declaration and setting its adapter. Did I miss anything? I tried adding verticalSpacing and padding separately but nothing's changed.
EDIT:
This is the setup in the whole layout:
Black is a RelativeLayout, FrameLayout and the last ImageView are aligned top and bottom respectively. Top TextView is below FrameLayout, bottom TextView is below top TextView. Now GridView is below bottom TextView and above ImageView, it should expand its height basing to the space left consumed between the first 3 elements and the bottom element. This is how it's setup in my layout.
I believe it's a layout problem more than in my code since I've done dozens of ListView and this has similar implementation.
EDIT2:
The layout:

Don't mind the ImageViews, I just took out their source. I needed to retain the setup from my actual layout. The code:
public class SixthActivity extends Activity {
private Integer[] gridViewItem = new Integer[] { 1, 2, 3, 4, 5, 6, 7, 8 };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sixth);
GridView gridView = (GridView) findViewById(R.id.grid_view);
CustomAdapter adapter = new CustomAdapter(this,
R.layout.item_module, gridViewItem);
gridView.setAdapter(adapter);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.sixth, menu);
return true;
}
}
The adapter:
public class CustomAdapter extends ArrayAdapter<Integer> {
private Context context;
private int resource;
private Integer[] moduleList;
public CustomAdapter(Context context, int resource,
Integer[] moduleList) {
super(context, resource, moduleList);
// TODO Auto-generated constructor stub
this.context = context;
this.resource = resource;
this.moduleList = moduleList;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View row = convertView;
ViewHolder holder = null;
if (row == null) {
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
row = inflater.inflate(resource, parent, false);
holder = new ViewHolder();
row.setTag(holder);
} else {
holder = (ViewHolder) row.getTag();
}
holder.tvModuleName = (TextView) row.findViewById(R.id.module_name);
holder.tvModuleImage = (ImageView) row.findViewById(R.id.module_image);
holder.tvModuleName.setText("SAMPLESAMPLE");
return row;
}
public class ViewHolder {
public ImageView tvModuleImage;
public TextView tvModuleName;
}
}
The item layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/item_module"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ImageView
android:id="#+id/module_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/module_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:ellipsize="end"
android:singleLine="true" />
</LinearLayout>
Try to add numbers to gridViewItem to add items enough to trigger the scrolling just like in my screenshots, and try taking out 1 or 2 items at the bottom such that that row would be incomplete to replicate my problem. Thanks.
