GridView onclick not responding with EditText

I want a Gridview with image and EditText. I want to show image in fullscreen on click and select that Gridview item to delete on long click.But the GridView events OnItemLongClickListener() and OnItemClickListener() are not responding with EditText, though they work when Edittext android:focusable="false" is set. I have tried many different solutions but none of them are working. here is my code:

textView.setText(web[position]);
imageView.setImageResource(Imageid[position]);
} else {
grid = (View) convertView;
}
return grid;
}
}
Any help would be appreciated.. thanks in advance..

try adding these lines in your EditText
android:focusable="false"
android:focusableInTouchMode="false"

So finally solved the problem.
I used gesturelistener and detected motion.
Thank You.

I created activity_main.xml which contains a parent RelativeLayout and under this a ListView named upperListView and initially set visibility gone. Below this I created a LinearLayout and for this I created two ListView for Name DataSet and Image DataSet. When data matches I create a UpdateAdapter in which I use addeddata.xml, in which a button and ImageView created and when it is a successful match then hidden list view visibility becomes Visible and this "addeddata.xml" loaded in listview. This I perform. It will work perfectly.But when first matches,i.e, CAT name match with the Cat image, data is not deleted from both of listview and CAT name again shown in below the new ListView.
How to manage to complete matches if the application crashes.

This has been discussed in the past, with using circular Listviews:
How to create a closed (circular) ListView?
Closed or circular Horizontal ListView Android

I just want when I scroll ImageView part then if Dog image matches with the right end side Dog name then image stick with the Dog Name Button and rest of the images remain scrolling.
For this here is what you could try:
after scrolling items in list1 and list2, iterate over each item in the shortest listview and check if item1(position) [tag] = item2(position) [tag] (so, if you have a match)
if true:
redraw screen like this: add a new listview at the bottom of the screen (below both listviews). This listview with contain both item1 and item2 (so it's litviewitem xml will be a linear layout with other two linear layouts, one containing the matched pet name and the other the matched pet picture)
remove item1(position) and item2(position) from listview1, listview2 (which means you have to remove, for example, dog name from listview pet names datasource, and dog image from listview pet pictures datasource and reset adapters to listviews)
this way you will continue to be able to scroll and match items from listview1 and listview2 - without the already matching items-, and also have a bottom listview with all the matching elements that cannot be matched any more
Hope this helps!

After spend couple of days I found the perfect solution for my question. I dynamically created the ImageView and also the ListView. Image data are populating in the ListView. After matching the text with right Image, I take that ImageView from the List and set in dynamically created ImageView. Following is my code.
public class MainActivity extends Activity implements OnScrollChangedListener, OnScrollListener{
int index = 0;
ImageView imageView1;
List<Integer> spectrum = new ArrayList<Integer>();
String[] animalName;
ImageView[] imageArray;
Button[] buttonArray;
ListView listView;
SpectrumAdapter spectrumAdapter;
ListView animalImage;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
animalName = new String[]{"CAT","DOG","COW","RAT","PARROT","HORSE","FISH"};
imageArray = new ImageView[animalName.length];
buttonArray = new Button[animalName.length];
LinearLayout inner1 = (LinearLayout)findViewById(R.id.innerLayout1);
LinearLayout inner2 = (LinearLayout)findViewById(R.id.innerLayout2);
ListView animalList = (ListView)findViewById(R.id.animalList);
NameAdapter nameAdapter = new NameAdapter(MainActivity.this,
-1, animalName);
animalList.setAdapter(nameAdapter);
for(int i=0;i<animalName.length;i++)
{
ImageView imageView = new ImageView(this);
imageView.setId(i);
RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,150);
imageView.setTag(i);
imageView.setLayoutParams(params1);
imageView.setVisibility(View.GONE);
imageArray[i] = imageView;
inner1.addView(imageView);
}
ListView listView = new ListView(this);
LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
listView.setLayoutParams(param);
inner2.addView(listView);
spectrum.add(R.drawable.horse);
spectrum.add(R.drawable.rat);
spectrum.add(R.drawable.cow);
spectrum.add(R.drawable.dog);
spectrum.add(R.drawable.fish);
spectrum.add(R.drawable.parrot);
spectrum.add(R.drawable.cat);
spectrumAdapter = new SpectrumAdapter(MainActivity.this,
-1, spectrum);
CircularListAdapter circularAdapter = new CircularListAdapter(spectrumAdapter);
listView.setAdapter(circularAdapter);
listView.setOnScrollListener(this);
}
class NameAdapter extends BaseAdapter {
private String[] animalName;
private Activity context;
public NameAdapter(Activity context, int textViewResourceId,
String[] animalName) {
super();
this.animalName = animalName;
this.context = context;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater inflater=context.getLayoutInflater();
convertView = inflater.inflate(R.layout.animalname, parent, false);
}
Button button=(Button)convertView.findViewById(R.id.button);
button.setText(animalName[position]);
return convertView;
}
public int getCount()
{
int size = animalName.length;
return size;
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
}
class SpectrumAdapter extends ArrayAdapter<Integer> {
private List<Integer> spectrum;
public SpectrumAdapter(Context context, int textViewResourceId,
List<Integer> spectrum) {
super(context, textViewResourceId, spectrum);
this.spectrum = spectrum;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if(view == null) {
view = new View(MainActivity.this);
}
view.setId(position);
view.setBackgroundResource(spectrum.get(position));
return view;
}
public int getCount()
{
int size = spectrum.size();
return size;
}
}
#Override
public void onScrollChanged() {
// TODO Auto-generated method stub
}
#Override
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
}
#Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
// TODO Auto-generated method stub
int childInt = view.getChildAt(0).getId();
String img1Text = this.getResources().getResourceEntryName(spectrum.get(childInt));
String bb = animalName[index];
if(bb.equalsIgnoreCase(img1Text))
{
ImageView img = imageArray[index];
img.setBackgroundResource(spectrum.get(childInt));
img.setVisibility(View.VISIBLE);
index++;
}
else
{
}
}
}
This is the perfect solution for the question. Thanks all for the suggestion.

Remove button in gridview

I have a gridview with 8 buttons, 2 rows and 4 columns. I am trying to delete a button or even a row..a row might be better..I want this deletion to take place when I click on a button..any button. I am having trouble with this. I will show you code so far:
Mainactivity:
public class MainActivity extends Activity {
private TextView text;
private GridView gridView;
private TextView timerValue;
private Boolean firstclick = false;
private long startTime = 0L;
private Handler customHandler = new Handler();
private Button buttonclicked;
Random r = new Random();
//private int[] rannumbers_array = new int[32];
private int[] shuffle_array = new int[4];
private String[] items = new String[8];
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
text = (TextView) findViewById(R.id.feedback);
timerValue = (TextView) findViewById(R.id.timerValue);
timerValue.setTextColor(Color.GREEN);
int j = 0;
int k = 0;
int ranval = 0;
for(int i = 0; i < 8; i++)
{
if ( (i % 4) == 0)
{
for(int x = 0; x < 4; x++)
{
shuffle_array[x] = 0;
}
do {
ranval = r.nextInt(100);
} while((ranval % 2) != 0);
}
else
{
do {
ranval = r.nextInt(100);
} while((ranval % 2) == 0);
}
shuffle_array[j] = ranval;
j++;
if(j >= 4)
{
j = 0;
shuffle(shuffle_array);
do {
items[k] = Integer.toString(shuffle_array[j]);
k++;
j++;
} while(k <= i);
j = 0;
}
//rannumbers_array[i] = r.nextInt(100);
//items[i] = Integer.toString(rannumbers_array[i]);
}
k = 0;
gridView = (GridView) this.findViewById(R.id.myGridView);
final CustomGridAdapter gridAdapter = new CustomGridAdapter(MainActivity.this, items);
gridView.setAdapter(gridAdapter);
buttonclicked = gridAdapter.getbutton();
gridView.post(new Runnable() {
public void run() {
gridView.setSelection(gridView.getCount() - 1);
}
});
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if(!firstclick)
{
customHandler.postDelayed(updateTimerThread, 0);
firstclick = true;
}
buttonclicked.setVisibility(view.GONE);

public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = inflater.inflate(R.layout.cell, null);
}
button = (Button) convertView.findViewById(R.id.grid_item);
button.setHeight(175);
button.setText(items[position]);
return convertView;

The buttonclicked.setVisibility(view.GONE); did not work, gave me an error I think. I am trying to have a button or item be clicked and have that item and/or the row the item is in to be deleted..how can I do this? What am I missing? After the deletion occurs I will need to redraw the grid to have less items in it too. Those are the two things that I am stumped on now

Use the view parameter on the OnItemClick implementation, this function give to you the position of the grid, the cell view and the id of the custom item on your adapter.
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if(!firstclick)
{
customHandler.postDelayed(updateTimerThread, 0);
firstclick = true;
}
//buttonclicked.setVisibility(view.GONE);
view.findViewById(R.id.grid_item).setVisibility(view.GONE);
}
}

Try to change the location of the declared input to OnCreate with final.

When I run the above code it selects multiple items with radiobutton, but I want a single item selection when I click a button so any idea how can I solve it?

No change at all. Just set adapter of GridView as your are setting for ListView.

I'd suggest that you use RecyclerView intead.
You might want to refer to the documentation and learn more about it.
I'm sharing my piece of code in which I'm changing my gridview to listview using RecyclerView
If you're using Android Studio then you might need to add dependencies in gradle build. In my case I added as follows:
dependencies {
.
.
.
compile 'com.android.support:recyclerview-v7:24.0.0'
}
First I'm defining a grid cell which is to be used in grid layout
recycler_cell.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:id="#+id/imageView2"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:background="#FF000000"
android:layout_marginLeft="0dp"
android:layout_marginRight="0dp"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:text="Small Text"
android:id="#+id/textView2"
android:layout_below="#+id/imageView2"
android:layout_alig=nParentStart="true"
android:layout_alignEnd="#+id/imageView2"
android:gravity="center"/>
</RelativeLayout>
Now I'm defining a list row which is to be used in list layout
recycler_row.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:id="#+id/imageView"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:background="#FF000000"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Large Text"
android:id="#+id/textView"
android:layout_alignParentTop="true"
android:layout_alignBottom="#+id/imageView"
android:layout_alignParentEnd="true"
android:layout_toEndOf="#+id/imageView"
android:gravity="center_vertical"
android:background="#FF333333"
android:textColor="#FFF"
android:padding="10dp"/>
</RelativeLayout>
recycler_view_test.xml
And of course define a layout which would contain RecyclerView
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/recyclerView"
android:layout_alignParentLeft="true"
android:layout_marginLeft="0dp"
android:layout_alignParentTop="true"
android:layout_marginTop="0dp"
android:layout_centerHorizontal="true"
>
</android.support.v7.widget.RecyclerView>
<Button
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Change Layout"
android:id="#+id/btnChange"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="62dp"/>
</RelativeLayout>
I'm sharing my piece of code but I'd strongly recommend that you go through the documentation and tutorials to understand RecyclerView to its full extent.
public class RecyclerViewTest extends AppCompatActivity
{
final int GRID = 0;
final int LIST = 1;
int type;
RecyclerView recyclerView;
RecyclerView.LayoutManager gridLayoutManager, linearLayoutManager;
MyAdapter adapter;
Button btnChange;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.recycler_view_test);
// Display contents in views
final List<Person> list = new ArrayList<>();
list.add(new Person("Ariq Row 1"));
list.add(new Person("Ariq Row 2"));
list.add(new Person("Ariq Row 3"));
// Finding views by id
recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
btnChange = (Button) findViewById(R.id.btnChange);
// Defining Linear Layout Manager
linearLayoutManager = new LinearLayoutManager(getApplicationContext());
// Defining Linear Layout Manager (here, 3 column span count)
gridLayoutManager = new GridLayoutManager(getApplicationContext(), 3);
//Setting gird view as default view
type = GRID;
adapter = new MyAdapter(list, GRID);
recyclerView.setLayoutManager(gridLayoutManager);
recyclerView.setAdapter(adapter);
//Setting click listener
btnChange.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View view)
{
if (type == LIST)
{
// Change to grid view
adapter = new MyAdapter(list, GRID);
recyclerView.setLayoutManager(gridLayoutManager);
recyclerView.setAdapter(adapter);
type = GRID;
}
else
{
// Change to list view
adapter = new MyAdapter(list, LIST);
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.setAdapter(adapter);
type = LIST;
}
}
});
}
}
//Defining Adapter
class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder>
{
List<Person> list;
int type;
final int GRID = 0;
final int LIST = 1;
MyAdapter(List<Person> list, int type)
{
this.list = list;
this.type = type;
}
// Inflating views if the existing layout items are not being recycled
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
{
View itemView;
if (viewType == GRID)
{
// Inflate the grid cell as a view item
itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_cell, parent, false);
}
else
{
// Inflate the list row as a view item
itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_row, parent, false);
}
return new ViewHolder(itemView, viewType);
}
// Add data to your layout items
#Override
public void onBindViewHolder(ViewHolder holder, int position)
{
Person person = list.get(position);
holder.textView.setText(person.name);
}
// Number of items
#Override
public int getItemCount()
{
return list.size();
}
// Using the variable "type" to check which layout is to be displayed
#Override
public int getItemViewType(int position)
{
if (type == GRID)
{
return GRID;
}
else
{
return LIST;
}
}
// Defining ViewHolder inner class
public class ViewHolder extends RecyclerView.ViewHolder
{
TextView textView;
final int GRID = 0;
final int LIST = 1;
public ViewHolder(View itemView, int type)
{
super(itemView);
if (type == GRID)
{
textView = (TextView) itemView.findViewById(R.id.textView2);
}
else
{
textView = (TextView) itemView.findViewById(R.id.textView);
}
}
}
}
// Data Source Class
class Person
{
String name;
Person(String name)
{
this.name = name;
}
}
If you end up with the issue to auto fit the number of columns in case of grid layout then you might want to check #s-marks's answer in which he extended the GridLayoutManager class and added his own patch of code, and also my fix if you start having weird column width.
In my case, using his solution I made a class as follows:
class GridAutofitLayoutManager extends GridLayoutManager
{
private int mColumnWidth;
private boolean mColumnWidthChanged = true;
public GridAutofitLayoutManager(Context context, int columnWidth)
{
/* Initially set spanCount to 1, will be changed automatically later. */
super(context, 1);
setColumnWidth(checkedColumnWidth(context, columnWidth));
}
public GridAutofitLayoutManager(Context context, int columnWidth, int orientation, boolean reverseLayout)
{
/* Initially set spanCount to 1, will be changed automatically later. */
super(context, 1, orientation, reverseLayout);
setColumnWidth(checkedColumnWidth(context, columnWidth));
}
private int checkedColumnWidth(Context context, int columnWidth)
{
if (columnWidth <= 0)
{
/* Set default columnWidth value (48dp here). It is better to move this constant
to static constant on top, but we need context to convert it to dp, so can't really
do so. */
columnWidth = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 48,
context.getResources().getDisplayMetrics());
}
else
{
columnWidth = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, columnWidth,
context.getResources().getDisplayMetrics());
}
return columnWidth;
}
public void setColumnWidth(int newColumnWidth)
{
if (newColumnWidth > 0 && newColumnWidth != mColumnWidth)
{
mColumnWidth = newColumnWidth;
mColumnWidthChanged = true;
}
}
#Override
public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state)
{
int width = getWidth();
int height = getHeight();
if (mColumnWidthChanged && mColumnWidth > 0 && width > 0 && height > 0)
{
int totalSpace;
if (getOrientation() == VERTICAL)
{
totalSpace = width - getPaddingRight() - getPaddingLeft();
}
else
{
totalSpace = height - getPaddingTop() - getPaddingBottom();
}
int spanCount = Math.max(1, totalSpace / mColumnWidth);
setSpanCount(spanCount);
mColumnWidthChanged = false;
}
super.onLayoutChildren(recycler, state);
}
}
Then you simply have to change:
gridLayoutManager = new GridLayoutManager(getApplicationContext(), 3);
and use your custom grid layout object, here 100 is the width of columns in dp
gridLayoutManager = new GridAutofitLayoutManager(getApplicationContext(), 100);

You can do something like this:
For the layout of the grid/list use a merge:
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ViewStub android:id="#+id/list"
android:inflatedId="#+id/showlayout"
android:layout="#layout/list_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"/>
<ViewStub android:id="#+id/grid"
android:inflatedId="#+id/showlayout"
android:layout="#layout/grid_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"/>
</merge>
then define the layout for the list and the grid (and also for their items), and manage the passage between them inflating the layouts, and then use a method like this to change the current view:
private void changeView() {
//if the current view is the listview, passes to gridview
if(list_visibile) {
listview.setVisibility(View.GONE);
gridview.setVisibility(View.VISIBLE);
list_visibile = false;
setAdapters();
}
else {
gridview.setVisibility(View.GONE);
listview.setVisibility(View.VISIBLE);
list_visibile = true;
setAdapters();
}
}
If you need the complete code, it is available in this article:
http://pillsfromtheweb.blogspot.it/2014/12/android-passare-da-listview-gridview.html

Just take a GridView object instead of Listview like :
GridView gridView;
gridView= (GridView) this.findViewById(R.id.gridView1);
And in you getView method of CategoryListAdapter3 do like :
convertView = inflater.inflate(R.layout.your_grid_item_leyout, null);
And at last in onPostExecute of TheTask do like :
gridView.setAdapter(cla);
That's It.

Use GridView instead of below:
Then replace
listview = (HorizontalListView) this.findViewById(R.id.listview2);
to
GridView gridview;
gridview=(GridView) findViewById(R.id.gridview);
Everything else are fine, just set Adapter using GridView object. And you are done.
