On clicking the button in listview item, change occurs in some others listview items too

I am making an app in which there are posts with comments and description. There are three buttons on each post. 1 description 2 comments and third is like button. I set a button click listener in getview method of custom adapter. When i click on description button the description of that post should be displayed under the button. But when i clicked the description button, the description of some other listview items also displayed. I just want to show the description of that post whose description button is clicked. Here is my code:
getview code:
public View getView(int position, View convertView, ViewGroup parent) {
a = getItem(position);
View view = convertView;
try
{
if (convertView == null) {
v = new ViewHolder();
convertView = LayoutInflater.from(getContext()).inflate(R.layout.custom_list_item, parent, false);
v.imgView = (ImageView) convertView.findViewById(R.id.iv_list_image);
v.desc = (Button) convertView.findViewById(R.id.btn_desc);
v.des = (TextView) convertView.findViewById(R.id.tv_list_desc);
v.ll = (LinearLayout) convertView.findViewById(R.id.ll_desc);
convertView.setTag(v);
}
else {
v = (ViewHolder) convertView.getTag();
}
v.desc.setTag(position);
//Picasso.with(getContext()).load(a.getFile()).fit().into(v.imgView);
Glide.with(context).load(a.getFile()).centerCrop().placeholder(R.drawable.dualring).into(v.imgView);
v.desc.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v1) {
Toast.makeText(getContext(), ""+v.desc.getTag(), Toast.LENGTH_SHORT).show();
v.des.setText(""+a.getDescription());
v.ll.setVisibility(View.VISIBLE);
}
});
return convertView;
}catch (Exception e)
{
return null;
}
}

That's when you use an int flag for the list item's position as a conditional statement before updating the ListView's items.
So in your case, the Adapter class would look something like this:
...
private int mPosition = -1; // Int flag that doesn't take effect UNTIL it has been set
...
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
a = getItem(position);
View view = convertView;
try {
if (convertView == null) {
v = new ViewHolder();
convertView = LayoutInflater.from(getContext()).inflate(R.layout.custom_list_item, parent, false);
v.imgView = (ImageView) convertView.findViewById(R.id.iv_list_image);
v.desc = (Button) convertView.findViewById(R.id.btn_desc);
v.des = (TextView) convertView.findViewById(R.id.tv_list_desc);
v.ll = (LinearLayout) convertView.findViewById(R.id.ll_desc);
convertView.setTag(v);
} else {
v = (ViewHolder) convertView.getTag();
}
v.desc.setTag(position);
//Picasso.with(getContext()).load(a.getFile()).fit().into(v.imgView);
Glide.with(context).load(a.getFile()).centerCrop().placeholder(R.drawable.dualring)
.into(v.imgView);
// Runs the following functionality if the positions match. Otherwise, hides the layout.
if (mPosition == position) {
Toast.makeText(getContext(), ""+v.desc.getTag(), Toast.LENGTH_SHORT).show();
v.des.setText(""+a.getDescription());
v.ll.setVisibility(View.VISIBLE);
} else {
v.ll.setVisibility(View.INVISIBLE);
}
v.desc.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v1) {
mPosition = position; // Sets the flag to the position that was clicked
notifyDataSetChanged(); // Updates the data instantly
}
});
return convertView;
} catch (Exception e) {
return null;
}
}
Let me know if that works.

The best way is to implement the on click listener in adapter and set the tag on button. After that in onclick method perform the desired task through getting tag id of button, this will definitely work.

how to hide view appear on top of previous selected row on click of another row inside GridView in android

I have a Fragment with custom Adapter extending BaseAdapter that manages a GridView.
I want to show images on each row of the GridView and onClick of each cell, I want to open a translucent view on top of that particular image which will show image details.
Problem is that when I click on the image, a translucent view opened on top of the image but when I click on next image then a translucent view opened on previous images is not hiding,it still appears over the first images..
See the following code
My Fragment
public class ProductFragment extends Fragment {
String ss = null;
GridView gridView;
ArrayList<ProductParameterBO> productlist;
GridViewCustomAdapter gridViewCustomAdapter;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

TextView configure = (TextView)rootView.findViewById(R.id.text_conf);
configure.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(getActivity(),SplitViewActivity.class);
intent.putExtra("firstTab","1stTabs");
startActivity(intent);
}
});
TextView text_here = (TextView)rootView.findViewById(R.id.text_here);
text_here.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
FloatingActionButton fab = (FloatingActionButton)rootView.findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {

startActivity(intent);
}
});
return rootView;
} else {
View rootView = inflater.inflate(R.layout.fragment_product,null);
gridView =(GridView)rootView.findViewById(R.id.gridView);
productlist = new ArrayList<ProductParameterBO>();
productlist.add(new ProductParameterBO("Type","Numeric","yes","yes"));
productlist.add(new ProductParameterBO("Typess","Numericss","yesss","yesss"));

Am I missing something? kindly help me to resolve this issue. I want a screen something like that. Am I doing right to open tranlucent screen on top of image and how to hide or make visivility gone on click of other images inside my Adater class.Any help would be appreciated in advanced

You can do one of two things.
1. Use a flag
NOTE this code is untested.
You can create an encapsulated flag in your ProductParameterBO object to determine the visibility of your overlay view. Something like the following
boolean mInformationViewVisible = false;
public void setInformationViewVisible(boolean visible) {
mInformationViewVisible = visible;
}
public boolean isInformationViewVisible() {
return mInformationViewVisible;
}
Then use that in your getView method to set the visibility of the view.
#Override
public View getView(int position,View convertView,final ViewGroup parent) {
...
holder.myImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
for(int itemPosition = 0; itemPosition < availList.size(); itemPosition++) {
if(itemPosition != position){
availList.get(itemPosition)
.setInformationViewVisible(false);
}
availList.get(itemPosition).setInformationViewVisible(true);
}
});
if (currentItem.isInformationViewVisible()) {
holder.rl.setVisibility(View.VISIBLE);
} else {
holder.rl.setVisibility(View.GONE);
}
...
}
2. Switch to RecyclerView
The second and better option is to switch to RecyclerView. This view is specifically built for individual interaction with items in your Adapter. It gives you more power over the View in terms of animations and removal/adittion of items to the adapter. You can read more on it here and here.
It is very likely that the app in the image you attached is using RecyclerView to manage their content. The code to manage the selected info view will be very similar in RecyclerView to what I posted for the ListView, the only difference would be that you would pass the OnClickListener to the RecyclerView.ViewHolder and set it to the info view in there in stead of in the getView() method. I highly recommend using this approach as it will benefit you in the future of your app.

In ProductParameterBO, you can keep a boolean member variable, and in getView() and if one image is clicked, you can set the boolean variables from that list as false, except the one you clicked. If the variable is true, it will display the image details, and if the variable is false, you can set the visibillty of the translucent view as Invisible of that particular position.
#Override
public View getView(int position,View convertView,final ViewGroup parent) {
View row = convertView;
final TeeTimeHolder holder;
if (row == null){
inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.grid_row,parent,false);
holder = new TeeTimeHolder();
holder.myImage =(ImageView)row.findViewById(R.id.imageView10);
holder.name =(TextView)row.findViewById(R.id.textView47);
holder.edit =(TextView)row.findViewById(R.id.textView49);
holder.rl =(RelativeLayout)row.findViewById(R.id.img_ovrly);
row.setTag(holder);
}
else {
holder =(TeeTimeHolder)row.getTag();
}
holder.name.setText(availList.get(position).getParameterName());
holder.myImage.setImageResource(R.drawable.toi);
holder.rl.setVisibility(View.GONE);
holder.myImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
View rows = null;
inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rows = inflater.inflate(R.layout.image_overlay,parent,false);
// holder.rl = (RelativeLayout)rows.findViewById(R.id.img_ovrly);
// holder.rl.setVisibility(View.VISIBLE);
for(int i=0;i<availList.size();i++){
if(i!=position){
availList.get(i).flag=false;
}
}
availList.get(position).flag=true;
}
});
if(availList.get(i).flag){
holder.rl.setVisibility(View.VISIBLE);
}else{
holder.rl.setVisibility(View.INVISIBLE);
}
return row;
}

Iterating the ListView and change content of some rows (ListItem)

I have a ListView whose ListItems(RelativeLayout) have
A textView and two ImageButtons inside a LinearLayout.
Here is the xml of my ListItem;
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:descendantFocusability="blocksDescendants"
>
<TextView
android:id="#+id/list_item_quote"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingBottom="15dp"
android:paddingTop="15dp"
style="#style/quote_text"
/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/lytShareLike"
android:layout_gravity="center"
android:gravity="center"
android:visibility="gone"
android:layout_margin="1dp"
android:layout_alignLeft="#id/list_item_quote"
android:layout_alignTop="#id/list_item_quote"
android:layout_alignRight="#id/list_item_quote"
android:layout_alignBottom="#id/list_item_quote">
<ImageButton
android:layout_width="30dp"
android:layout_height="30dp"
android:scaleType="centerInside"
android:id="#+id/btnShare"
android:background="#null"
android:onClick="quoteShareClick"
android:src="#drawable/share"
android:layout_marginRight="10dp"
/>
<ImageButton
android:layout_width="30dp"
android:layout_height="30dp"
android:scaleType="centerInside"
android:id="#+id/btnLike"
android:background="#null"
android:src="#drawable/heartnot"
android:onClick="quoteLikeClick"
/>
</LinearLayout>
</RelativeLayout>
I have ItemClickListener which sets the LinearLayout visible when the ListItem is clicked. There is no problem until here.
What I want to do is, after clicking a ListItem, if the user clicks another ListItem, the other unclicked Listitems' LinearLayouts should be GONE again.
Here is my onClickListener;
listQuotes.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
LinearLayout lytShareLike = (LinearLayout) view.findViewById(R.id.lytShareLike);
for (int i = 0; i < listQuotes.getAdapter().getCount(); i++) {
if (position != i && i != 0) {
LinearLayout lnrTemp = (LinearLayout) listQuotes.getAdapter().getView(i, null, null).findViewById(R.id.lytShareLike);
lnrTemp.setVisibility(View.GONE);
}
}
}
});
The for iteration iterates the items and LinearLayouts as expected but the LinearLayouts are still VISIBLE
What am I missing?

you can control it by using below code：
//...
int index = -1;
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
index = position;
mAdaper..notifyDataSetChanged();
}
//...
in the adapter：
#Override
public View getView(int position, View convertView, ViewGroup parent) {
//...
Holder holder;
if(convertView == null) {
convertView = ....;
holder = new Holder(convertView);
convertView.setTag(holder);
}
holder = (Holder) convertView.getTag();
if(index == position){
holder.linearLayout.setVisibility(View.VISIBLE);
} else {
holder.linearLayout.setVisibility(View.GONE);
}
//...
return convertView;
}

Toggle a "ToggleButton" when clicking anywhere outside it

I have a list (ExpandableListView), and every item of the list has a ToggleButton that shows/hides the child items when toggled (the child is always 1 and it's a sort of toolbar with two buttons). Thanks to this tutorial I could set a custom button instead of the expandablelistview's indicator and I made it so that I can do something else than showing the toolbar when clicking on a list item. Also, I used the answer to this question to automatically close an open toolbar when opening another one.
So, I need to collapse the currently expanded toolbar when touching anything on the screen that is not its ToggleButton (I would need to collapse it even when clicking on one of the toolbar's buttons, as long as its own "onClick" is sent anyway).
here's an image of the app:
Here's the ExpandableListView:
<ExpandableListView

And finally the important parts in the activity:
lv = (ExpandableListView)findViewById(R.id.normalList);
lv.setGroupIndicator(null);
lv.setOnGroupClickListener(new OnGroupClickListener() {
public boolean onGroupClick(ExpandableListView parent, View v, int position, long id) {
//do some things
return true; //this tells the list that it mustn't show the child items
}
});
adapter = new CustomList(myActivity.this, list, icons);
lv.setAdapter(adapter);
P.S.: The code to hide the open toolbars doesn't work properly, but I really can't understand why. But this is another story...
--- EDIT ---
About the P.S. above: now I know why that happens.

Your list looks like ExpandableListView. Did you try to use it? It has build it second level rows, expanding, hiding, etc. Simply add your pdf rows as group headers and then add tool rows as child rows. Then you can handle row clicks to show and hide rows you would like to show/hide. See: http://developer.android.com/reference/android/widget/ExpandableListView.html
And, btw., using additional rows with hiding is a bit wrong UX design. Maybe it would be better to use drop down lists or custom dialog windows? Both of them have built in functionality do disappear when touched outside.

You can simply put all your ToggleButton whenfilling the list in an ArrayList. This way you just have to force the click on each button of list toggled when one of them is clicked.

Ok I solved the problem.
Instead of toggling the buttons with "performClick()" or "setChecked" in some methods and managing the expand/collapse action in an OnCheckedChangedListener, I decided to store the status of the togglebuttons in an array, and to expand/collapse the child views in the "getGroupView" method depending on the state of the groupview's button, whose position in the array corresponds to the groupview's position in the list. To update the list, I call notifyDataSetChanged() on the adapter.
I added a FrameLayout around the ToggleButton to increase its clickable area.
Here's the code for clarity:
The relevant parts of the MainActivity:
public class MainActivity extends ActionBarActivity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
.
.
.
ExpandableListView lv = (ExpandableListView) findViewById(R.id.normalList);
CustomList adapter = new CustomList(MainActivity.this, list /*the list of Items, declared elsewhere*/, lv);
lv.setAdapter(adapter);
DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.filesListDrawerLayout);
lv.setOnGroupClickListener(new OnGroupClickListener() {
public boolean onGroupClick(ExpandableListView parent, View v, int position, long id) {
uncheckButtons(mDrawerLayout);
//do some unrelated stuff
return true;
}
});
}
public void uncheckButtons(ViewGroup vg) {
for(int i = 0; i < adapter.buttons.length; ++i)
adapter.buttons[i] = false;
adapter.lastChecked = -1;
adapter.notifyList();
}
The relevant parts of the adapter:
