Cannot resolve layout in adapter for custom list view

I am trying to make a custom ListView and a adapter for that list, I am inflating the list view layout but it is giving an error saying
Cannot find symbol variable lv_grpMsg
Can someone tell me how to correct this error?
Here is the adapter code:
public class GrpMsgAdapter extends BaseAdapter{
private Fragment fragment;
private ArrayList data;
private static LayoutInflater layoutInflater = null;
public Resources resources;
GrpMsgModel grpMsgModel = null;
int i = 0;
public GrpMsgAdapter(Fragment fragment, ArrayList data, Resources resources){
this.fragment = fragment;
this.data = data;
this.resources = resources;
layoutInflater = (LayoutInflater)this.fragment.getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
if(data.size() <= 0)
return 1;
return data.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
public static class ViewHolder{
public ImageView iv_grpMsgDp;
public TextView tv_grpMsgName, tv_grpMsgNoMem;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
ViewHolder viewHolder;
if(convertView == null) {
view = layoutInflater.inflate(android.R.layout.lv_grpmsg, null);
viewHolder = new ViewHolder();
viewHolder.iv_grpMsgDp = (ImageView) view.findViewById(R.id.iv_grpMsgDp);
viewHolder.tv_grpMsgName = (TextView) view.findViewById(R.id.tv_grpMsgName);
viewHolder.tv_grpMsgNoMem = (TextView) view.findViewById(R.id.tv_grpMsgNoMem);
view.setTag("holder");
}
else{
viewHolder = (ViewHolder)view.getTag();
}
if(data.size() <= 0){
viewHolder.tv_grpMsgName.setText("No data");
}
else{
grpMsgModel = null;
grpMsgModel = (GrpMsgModel)data.get(position);
viewHolder.tv_grpMsgName.setText(grpMsgModel.getGrpName());
viewHolder.tv_grpMsgNoMem.setText(grpMsgModel.getNoMem());
viewHolder.iv_grpMsgDp.setImageResource(resources.getIdentifier("com.example.nmss.coach" + grpMsgModel.getImageURL(), null, null));
}
return view;
}
}
My ListView layout code is:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/relGrpMsg">
<ImageView
android:id="#+id/iv_grpMsgDp"
android:layout_width="80dp"
android:layout_height="80dp"
android:layout_marginStart="18dp"
app:srcCompat="#mipmap/ic_launcher_round"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:layout_marginTop="12dp" />
<TextView
android:id="#+id/tv_grpMsgName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Group name"
android:layout_alignTop="#+id/iv_grpMsgDp"
android:layout_toEndOf="#+id/iv_grpMsgDp"
android:layout_marginStart="80dp" />
<TextView
android:id="#+id/tv_grpMsgNoMem"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/iv_grpMsgDp"
android:layout_alignStart="#+id/tv_grpMsgName"
android:layout_marginBottom="15dp"
android:text="No. of members" />
<CheckBox
android:id="#+id/cb_grpMsgSel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/tv_grpMsgNoMem"
android:layout_alignParentEnd="true"
android:layout_marginEnd="24dp" />
</RelativeLayout>

It should be R.layout.lv_grpmsg not android.R.layout.lv_grpmsg

use R.layout.lv_grpmsg instead ofandroid.R.layout.lv_grpmsg
and other mistake is view.setTag("holder");
correct one is view.setTag(viewHolder);

How to change view after click?

I do design. And i am not know how.
if I clik on the item, should appear red view in right side.
I am use GridView and my adapter public class BasketAdapter extends BaseAdapter

I will add something else if necessary. may have a library ready?

Change your ImageView by click gridview item:
gridView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
ViewHolder holder = (ViewHolder)view.getTag();
//set your new image here
holder.imageview.setImageResource(R.id.yourImage);
... ...
//maybe also update items content in 'position' if need
}
});
Hope this help!

ListView is showing gapes in list items Android

i am trying to implement listView through setListAdapter and Efficient Adapter. I want that when list is show then the background should not be repeat. My code is repeating the whole layout of list.xml due to which my list item are showing with so much gap.
Right now my list is working like that:
But i want this type of view:
Here is my editText.xml in which i type the word and a list View is opened.
<EditText
android:id="#+id/start_edit"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_gravity="top|left"
android:ems="10"
android:hint="Type to search"
android:paddingLeft="50dp" >
<requestFocus />
</EditText>
this layout is for list.xml :
<RelativeLayout
android:id="#+id/RelativeLayout_list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/blue_cellbar" >
the list.xml file is repeating the layout in Effecient adapter:
here is my code:
listAdapter = new EfficientAdapter2(this);
setListAdapter(listAdapter);
public static class viewHolder2 {
TextView word;
TextView meaning;
ImageView image;
ImageView image_color;
RelativeLayout cell;
}
private class EfficientAdapter2 extends BaseAdapter implements Filterable,OnItemClickListener {
private Context context;
LayoutInflater inflater;
public EfficientAdapter2(Context context) {
this.context = context;
inflater = LayoutInflater.from(context);
}
public int getCount() {
// if(SearchWordString.isEmpty()==false)
// {
return SearchWordString.size();
/// }
//return 0;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
viewHolder2 holder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.list, null);
ViewToUse=parent;
holder = new viewHolder2();
// Log.i("View","is Null");
convertView.setTag(holder);
} else {
//Log.i("View","is not Null");
holder = (viewHolder2) convertView.getTag();

holder.cell = (RelativeLayout) convertView

I hope you have not provide android:dividerHeight attribute in your layout file under <ListView/>
If so please remove it.

this problem occurs when you have set the adapter class xml, parent root
match_content instead of wrap_content.
set the root content height wrap_content
As i can see in adapter layout there is no parent root like relative, linearlayout, Framelayout and ConstraintLayout etc.

Gridview's order of child items changes while softkeypad pops up

My activity contains a textview and under that it has gridview elements. Stage 1: When the activity starts, it adjusts the elements in the order that I have set(like item1, item2,..) stage1 picture. Stage 2: But when I click on edittext, the gridview elements get adjusted to allocate space for the softkeypad stage2 picture. Stage 3: So when I press back button, the soft keypad disappears(as usual), but the order of gridview elements are getting changed stage3 picture. The order of child items of gridview changes. Can anyone please suggest me how to avoid this uncertainty in the order? Below is my entire code and xml file, though I think these are not that much necessary to solve this issue.
public class PresentActivity extends Activity {
GridView gridView;
static final String[] TEXT = new String[] {
"item1", "item2","item3", "item4", "item5","item6","item7","item8" };
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setGridView();
}
public void setGridView()
{
gridView = (GridView)findViewById(R.id.gridView1);
gridView.setAdapter(new ImageAdapter(this, TEXT));
gridView.setNumColumns(3);
gridView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
String currentText=(String) ((TextView)v.findViewById(R.id.grid_item_label)).getText();
Toast.makeText(getApplicationContext(), currentText, Toast.LENGTH_SHORT).show();
}
});
}
}
Here is my custom adapter class.
public class ImageAdapter extends BaseAdapter{
private Context context;
private final String[] textValues;
public ImageAdapter(Context context, String[] textValues) {
this.context = context;
this.textValues = textValues;
}
#Override
public int getCount() {
return textValues.length;
}
#Override
public Object getItem(int arg0) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View gridView;
if (convertView == null) {
gridView = new View(context);
// get layout from imagewithtext.xml
gridView = inflater.inflate(R.layout.imagewithtext, null);
// set value into textview
TextView textView = (TextView) gridView
.findViewById(R.id.grid_item_label);
textView.setText(textValues[position]);
// set image based on selected text
ImageView imageView = (ImageView) gridView
.findViewById(R.id.grid_item_image);
String extractedText = textValues[position];
System.out.println("the position value is>>>>>>"+position);
if (extractedText.equals("item1")) {
imageView.setImageResource(R.drawable.icon);
}
else if (extractedText.equals("item2")) {
imageView.setImageResource(R.drawable.icon);
} else if (extractedText.equals("item3")) {
imageView.setImageResource(R.drawable.icon);
}else if(extractedText.equals("item4")){
imageView.setImageResource(R.drawable.icon);
} else if (extractedText.equals("item5")) {

Let's assume your items contain just 1 ImageView and 1 TextView (for the sake of simplicity).
Your getView method in the Adapter should do this:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder vh;
if (convertView == null) {
final LayoutInflater inflater = LayoutInflater.from(getContext());
convertView = inflater.inflate(R.layout.imagewithtext,null);
//Custom ViewHolder, you have to create it in the same class.
vh = new ViewHolder();
vh.imageView = convertView.findViewById(R.id.imageView1);
vh.textView = convertView.findViewById(R.id.textView1);
convertView.setTag(vh);
} else {
vh = (ViewHolder) convertView.getTag();
}
vh.imageView.setImageResource(R.drawable.whatever);
vh.textView.setText("Whatever text you want to set here");
return gridView;
}
And in your adapter, just add this:
private class ViewHolder{
public ViewHolder(){}
public ImageView imageView;
public TextView textView;
//Add any views you want to use in getView here
}

GridViewActivity:-(This is main Activity)
public class GridVieweActivity extends Activity {
GridView gridView;
static final String[] TEXT = new String[] { "item1", "item2", "item3",
"item4", "item5", "item6", "item7", "item8" };
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setGridView();
}
public void setGridView() {
gridView = (GridView) findViewById(R.id.gridView1);
gridView.setAdapter(new ImageAdapter(this, TEXT));
gridView.setNumColumns(3);
gridView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
String currentText = (String) ((TextView) v
.findViewById(R.id.textView1)).getText();
Toast.makeText(getApplicationContext(), currentText,
Toast.LENGTH_SHORT).show();
}
});
}
}
ImageAdapter:-
public class ImageAdapter extends BaseAdapter {
private Context context;
private final String[] textValues;
public ImageAdapter(Context context, String[] textValues) {
this.context = context;
this.textValues = textValues;
}
#Override
public int getCount() {
return textValues.length;
}
#Override
public Object getItem(int arg0) {
return null;

// get layout from imagewithtext.xml

// set value into textview

// set image based on selected text

.findViewById(R.id.imageView1);
String extractedText = textValues[position];
System.out.println("the position value is>>>>>>" + position);
if (extractedText.equals("item1")) {
imageView.setImageResource(R.drawable.ic_launcher);
} else if (extractedText.equals("item2")) {
imageView.setImageResource(R.drawable.ic_launcher);

The above code is working fine.

Are these GridView in Android?

I want to make an app with a interface like google+ or evernote like the following , how to perform these ui? Use GridView in Android?

They are similar to that. But they have their own term called DashBoard.
Here is a link on a tutorial,
DashBoard..
Here is a link which explains few things to you,
http://android-developers.blogspot.in/2010/05/twitter-for-android-closer-look-at.html
And also this question here, which was previously discussed about it,
Android Dashboard Pattern
And this looks to be the suggested way to do it,
<com.google.android.apps.iosched.ui.widget.DashboardLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button android:id="#+id/home_btn_schedule"
style="#style/DashboardButton"
android:text="#string/btn_schedule"
android:drawableTop="#drawable/home_btn_schedule" />
<Button android:id="#+id/home_btn_map"
style="#style/DashboardButton"
android:text="#string/btn_map"
android:drawableTop="#drawable/home_btn_map" />
<Button android:id="#+id/home_btn_sessions"
style="#style/DashboardButton"
android:text="#string/btn_sessions"
android:drawableTop="#drawable/home_btn_sessions" />
<Button android:id="#+id/home_btn_starred"
style="#style/DashboardButton"
android:text="#string/btn_starred"
android:drawableTop="#drawable/home_btn_starred" />
<Button android:id="#+id/home_btn_vendors"
style="#style/DashboardButton"
android:text="#string/btn_vendors"
android:drawableTop="#drawable/home_btn_vendors" />
<Button android:id="#+id/home_btn_announcements"
style="#style/DashboardButton"
android:text="#string/btn_announcements"
android:drawableTop="#drawable/home_btn_announcements" />
Taken From Here..

public class Dashboard extends Activity
implements OnItemClickListener {
Context con;
static LauncherIcon[] ICONS = {
new LauncherIcon(R.drawable.breakfasdd, "text1"),
new LauncherIcon(R.drawable.lunch, "text2"),
new LauncherIcon(R.drawable.dinner1, "text3"),
new LauncherIcon(R.drawable.syn1, "text4"),
};
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dashboard);
GridView gridview = (GridView) findViewById(R.id.dashboard_grid);
gridview.setAdapter(new ImageAdapter(this));
gridview.setOnItemClickListener(this);
}
static class LauncherIcon {
final String text;
final int imgId;
public LauncherIcon(int imgId, String text) {
super();
this.imgId = imgId;
this.text = text;
}
}
static class ImageAdapter extends BaseAdapter {
private Context mContext;
public ImageAdapter(Context c) {
mContext = c;
}
#Override
public int getCount() {
return ICONS.length;
}
#Override
public LauncherIcon getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
static class ViewHolder {
public ImageView icon;
public TextView text;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
ViewHolder holder;
if (v == null) {
LayoutInflater vi = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.dashboard_icon, null);
holder = new ViewHolder();
holder.text = (TextView) v
.findViewById(R.id.dashboard_icon_text);
holder.icon = (ImageView) v
.findViewById(R.id.dashboard_icon_img);
v.setTag(holder);
} else {
holder = (ViewHolder) v.getTag();
}
holder.icon.setImageResource(ICONS[position].imgId);
holder.text.setText(ICONS[position].text);
return v;
}
}
and to get item selected
#Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
int pos = position;{
}
