How to get the ID of an image from a string array

How to get the ID of an image from a string array - android

I created a custom adapter for my GridView that will display an image of a book (View image) and its name (View text);
, I declared the list of names of the books in the string file:
[strings.xml]
<string-array name="bookLabels">
<item>android security</item>
<item>penetration_testing</item>
<item>red_team</item>
<item>Linux Firewalls</item>
<item>the_art_of_exploitation</item>
<item>web_application_hacker</item>
<item>Linux Basicsfor Hackers</item>
<item>Black Hat Python</item>
</string-array>
So I want to do the same thing with the images,instead of declaring them in the code like that :
private Integer[] bookImages =
{
R.drawable.android_security,
R.drawable.penetration_testing,
R.drawable.red_team,
R.drawable.lf,
R.drawable.the_art_of_exploitation,
R.drawable.web_application_hacker,
R.drawable.lbh,
R.drawable.bhp
};
I declared the names of the images in a string array named "bookImages",
<string-array name="bookImages">
<item>#drawable/android_security</item>
<item>#drawable/penetration_testing</item>
<item>#drawable/red_team</item>
<item>#drawable/lf</item>
<item>#drawable/the_art_of_exploitation</item>
<item>#drawable/web_application_hacker </item>
<item>#drawable/lbh </item>
<item>#drawable/bhp </item>
</string-array>
and then I recovered the location of all the images declared in to "bookimagesfromstring"array :
Resources resi = context.getResources();
bookImagesFromString = resi.getStringArray(R.array.bookImages);
System.out.println("bookImages Images test 1: " +
Arrays.toString(bookImagesFromString))
this is the source code of [main activity]
public class main extends AppCompatActivity {
String[] labels;
String[ ] pages;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
Resources res = getResources();
labels = res.getStringArray(R.array.bookLabels);
pages = res.getStringArray(R.array.web_pages);
GridView gridView = findViewById(R.id.gridView1);
BookGrid myAdapter = new BookGrid(getApplicationContext(), labels);
gridView.setAdapter(myAdapter);
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
Toast.makeText(
getApplicationContext(),
((TextView) v.findViewById(R.id.gridtextView))
.getText(), Toast.LENGTH_SHORT).show();
// Intent webPageIntent = new Intent(getApplicationContext(),
DisplayWebPage.class);
// webPageIntent.putExtra("WEB_PAGE", pages[ position ] );
// startActivity( webPageIntent );
}
});
}
}
And the [ BookGrid Class ]
public class BookGrid extends BaseAdapter {
private Context context;
private LayoutInflater inflater;
private String[] imageName;
private String[] bookImagesFromString;
private Integer[] bookImages =
{
R.drawable.android_security,
R.drawable.penetration_testing,
R.drawable.red_team,
R.drawable.lf,
R.drawable.the_art_of_exploitation,
R.drawable.web_application_hacker,
R.drawable.lbh,
R.drawable.bhp
};
public BookGrid(Context context, String[] imageName) {
this.context = context;
this.imageName = imageName;
this.inflater = LayoutInflater.from(context);
}
#Override
public int getCount() {
return bookImages.length;
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
/*
Resources rest = context.getResources();
String[] labels = rest.getStringArray(R.array.bookLabels);
System.out.println("bookImagess Tex: " + Arrays.toString(labels));
*/
Resources resi = context.getResources();
bookImagesFromString = resi.getStringArray(R.array.bookImages);
System.out.println("bookImages Images test 1: " + Arrays.toString(bookImagesFromString));
if (convertView == null) {
convertView = inflater.inflate(R.layout.layout_grid_image, parent, false);
TextView txtv = convertView.findViewById(R.id.gridtextView);
ImageView imgv = convertView.findViewById(R.id.gridImageView);
//To Avoid ArrayIndexOutOfBoundsException
//boolean inBounds = (position >= 0) && (position <= imageName.length);
txtv.setText(imageName[position]);
//imgv.setImageResource(bookImagesFromString[position]);
imgv.setImageResource(bookImages[position]);
} else {
}
return convertView;
}
the result for the "bookImagesFromString" array was as follows :
([res/drawable-v24/android_security.png, res/drawable-v24/penetration_testing.png, res/drawable-v24/red_team.png, res/drawable/lf.jpg, res/drawable-v24/the_art_of_exploitation.png, res/drawable-v24/web_application_hacker.png, res/drawable/lbh.png, res/drawable-v24/bhp.png])
So the question is how to convert the "bookImagesFromString" array to an array that contains the ID of each image ? -And after using it in this code part:
imgv.setImageResource(bookImagesID[position]);
Thanks.

Try string array like this:
<string-array name="bookImages">
<item>android_security</item>
<item>penetration_testing</item>
<item>red_team</item>
<item>lf</item>
<item>the_art_of_exploitation</item>
<item>web_application_hacker</item>
<item>lbh</item>
<item>bhp</item>
</string-array>
and adapter like this:
public class BookGrid extends BaseAdapter {
private Context context;
private LayoutInflater inflater;
private String[] imageName;
private Integer[] bookImages;
public BookGrid(Context context, String[] imageName) {
this.context = context;
this.imageName = imageName;
this.inflater = LayoutInflater.from(context);
Resources resi = context.getResources();
String[] bookImagesFromString = resi.getStringArray(R.array.bookImages);
bookImages = new Integer[bookImagesFromString.length];
for (int i = 0; i < bookImagesFromString.length; i++) {
bookImages[i] = (resi.getIdentifier(bookImagesFromString[i], "drawable", context.getPackageName()));
}
}
#Override
public int getCount() {
return imageName.length;
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
/*
Resources rest = context.getResources();
String[] labels = rest.getStringArray(R.array.bookLabels);
System.out.println("bookImagess Tex: " + Arrays.toString(labels));
*/
if (convertView == null) {
convertView = inflater.inflate(R.layout.layout_grid_image, parent, false);
}
TextView txtv = convertView.findViewById(R.id.gridtextView);
ImageView imgv = convertView.findViewById(R.id.gridImageView);
txtv.setText(imageName[position]);
imgv.setImageResource(bookImages[position]);
return convertView;
}
}
Hope that helps!

for the name of the images as I_A_Mok said I took just:
<string-array name="bookImages">
<item>android_security</item>
<item>penetration_testing</item>
<item>red_team</item>
<item>lf</item>
<item>the_art_of_exploitation</item>
<item>web_application_hacker </item>
<item>lbh </item>
<item>bhp </item>
</string-array>
So I had two solutions :
A method with Context:
public static Integer[] getIds(Context context, String[] str) {
Integer[] bookID = new Integer[str.length];
for (int i = 0; i < str.length; i++) {
bookID[i] = context.getResources().getIdentifier(str[i], "drawable", context.getPackageName());
}
return bookID;
}
Or without Context (this approach is faster than the first Retrieving Resources in Android) :
public static Integer[] getIds(String[] str) {
Integer[] bookID = new Integer[str.length];
try {
for (int i = 0; i < str.length; i++) {
Class res = R.drawable.class;
Field field = res.getField(str[i]);
int drawableId = field.getInt(null);
bookID[i] = drawableId;
}
} catch (Exception e) {
Log.e("MyTag", "Failure to get drawable id.", e);
e.printStackTrace();
}
return bookID;
}
and here is the complete code
package com.example.gridview.BookGridWebView;

}

bookImagesFromStringArray =
context.getResources().getStringArray(R.array.bookImageName);
//the table contains the IDs of each Image
Integer[] bookIDs = getIds(context,bookImagesFromStringArray);
if (convertView == null) {
convertView = inflater.inflate(R.layout.layout_grid_image, parent, false);
TextView txtv = convertView.findViewById(R.id.gridtextView);
ImageView imgv = convertView.findViewById(R.id.gridImageView);
txtv.setText(imageName[position]);
// imgv.setImageResource(bookImages[position]);
imgv.setImageResource(bookIDs[position]);
} else {
}
return convertView;
}
public static Integer[] getIds(Context context, String[] str) {
Integer[] bookID = new Integer[str.length];
for (int i = 0; i < str.length; i++) {
bookID[i] = context.getResources().getIdentifier(str[i], "drawable", context.getPackageName());
}
return bookID;
}
public static Integer[] getIds(String[] str) {

<item>yuma</item>

</resources>
I can set an ImageView using
ImageView imgQuestion, imgAnswer, temp;
static ArrayList<String> arrayName;
public static ArrayList<HinhAnh> arrayImg;
String questionName;
int REQUEST_CODE_IMG = 2703;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imgAnswer = findViewById(R.id.imgAnswer);
imgQuestion = findViewById(R.id.imgQuestion);
String[] mangTen = getResources().getStringArray(R.array.list_name);
arrayName = new ArrayList<>(Arrays.asList(mangTen));
arrayImg = new ArrayList<>();
Collections.shuffle(arrayName);
**int idImg = getResources().getIdentifier(arrayName.get(1), "drawable", getPackageName());
imgQuestion.setImageResource(idImg);**
But I dont know how to add the list of images in to the arrayImg, I used:
for (int position = 0; position < arrayName.size(); position++){
int id = getResources().getIdentifier(arrayName.get(position), "drawable", getPackageName());
arrayImg.add(new HinhAnh(arrayName.get(position) + "", id));
Toast.makeText(this, arrayImg.get(1).getTen() + "", Toast.LENGTH_SHORT).show();
}
I used Toast to check if I add successfully then the error showed out
Caused by: java.lang.IndexOutOfBoundsException: Index: 1, Size: 1

My class HinhAnh
public class HinhAnh {
private String Ten;
private int Hinh;
public HinhAnh(String ten, int hinh) {
Ten = ten;
Hinh = hinh;
}
public String getTen() {
return Ten;
}
public void setTen(String ten) {
Ten = ten;
}
public int getHinh() {
return Hinh;
}
public void setHinh(int hinh) {
Hinh = hinh;
}
}
They all lead to my adapter is null then I cannot fill my gridview at all. Please help!!
Edit:
I changed the line to get(position) then it worked. But it still showed error point to my adapter, here's my adapter:
public class ImageAdapter extends BaseAdapter {
private Context context;
private int layout;
private List<HinhAnh> imageList;
public ImageAdapter(Context context, int layout, List<HinhAnh> imageList) {
this.context = context;
this.layout = layout;
this.imageList = imageList;
}
#Override

return 0;
}
#Override

}
#Override

return 0;
}
private class ViewHolder{
ImageView imgHinh;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if(convertView == null){
holder = new ViewHolder();
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(layout, null);
holder.imgHinh = convertView.findViewById(R.id.imgItem);
convertView.setTag(holder);
}
else{
holder = (ViewHolder) convertView.getTag();
}
holder.imgHinh.setImageResource(imageList.get(position).getHinh());
return convertView;
}
}
and where I called it
adapter = new ImageAdapter(this, R.layout.imageline, MainActivity.arrayImg);
gridView.setAdapter(adapter);
The error:
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.GridView.setAdapter(android.widget.ListAdapter)' on a null object reference
at com.example.intentpractice.Answers.onCreate(Answers.java:18)
Solved, I forgot returning getCount to array.size().
Thanks all!!!

There is a issue in your for loop for adding the images into the list.
For the position 0, there will be only one element in the arrayImg but you are calling arrayImg.get(1) which is causing java.lang.IndexOutOfBoundsException
change that line to:
for (int position = 0; position < arrayName.size(); position++){
int id = getResources().getIdentifier(arrayName.get(position), "drawable", getPackageName());
arrayImg.add(new HinhAnh(arrayName.get(position) + "", id));
Toast.makeText(this, arrayImg.get(position).getTen() + "", Toast.LENGTH_SHORT).show();
}

check size of image on checkbox click

I have a GridView which shows all the images from phone. I'm able to select multiple images and save the selected images to arraylist. I want to restrict the size of the selected images to 1MB. For that I want to check the size of every image while selecting. If the size of clicked image is less than 1MB then it will get selected, otherwise not. Is there any way to do that?

Custom Adapter not populating GridView

I have made a custom adapter to populate my gridView. What I am doing is that i am trying to populate the gridview with two different data(that too are custom) which are: Movies and FavouriteMovies. when the dridview is updated using Movies it updates just fine but when it FavouriteMovies it does not. I am storing FavouriteMovies in a sqlite db and then querying it to return a cursor.the data returns perfectly and there is no error. the main problem is with my MoviesAdapter. inside this when i add Movies to adapter it adds to the list inside MoviesAdapter and it works perfectly but when I add FavouriteMovies to the adapter it does not add it inside the favouriteList inside MoviesAdapter and its size is always zero.
please help!!

and here is where I am adding to the adapter:
#Override
protected void onPostExecute(Movies[] strings) {
if (strings != null) {
mMoviesAdapter.clear();
for (Movies moviesStr : strings) {
mMoviesAdapter.add(moviesStr);
}
}else if(mFavouriteMovies != null){
mMoviesAdapter.clear();
for(FavouriteMovies favouriteMoviesStr : mFavouriteMovies){
mMoviesAdapter.offlineAdd(favouriteMoviesStr);
}
}
Log.v("FetchMoviesTask","Count :" + mMoviesAdapter.getItem(0));
mMoviesAdapter.notifyDataSetChanged();
}
So sorry for my crude language.

You will always have count == 0 if you set your favorite movies.
List<Movies> list = new ArrayList<>();
#Override
public int getCount() {
if (list != null)
return list.size();
else
return favouriteList.size();
}
This will always return a count of 0 since list never is null. You favorite movies get ignored.
Solutions
Since you are only displaying either movies or favorites you should use 2 adapters. If you don't want to do this,
Use a boolean. Just set showFavorites to true, and display those. Or if you keep your null checks,
set the List<Movie> = null; when displaying favorited, then it will also work.

use following adapter:-
boolean[] CheckedItem_Adap;
ImageLoader imgload;
int headercount = 0, childCount;
LinkedList<HashMap<String, String>> allData;
LinkedList<HashMap<String, String>> temp_Header;
LinkedList<HashMap<String, String>> temp_child = new LinkedList<HashMap<String, String>>();

How to add data to custom BaseAdapter for listView - Android

I have a custom BaseAdapter class that creates views for comments, usernames, and numbers. This BaseAdapter receives this information from An AsyncTask. The AsyncTask runs when the user reaches the bottom of the listView. The problem is the BaseAdapter wont add new data. When I try to add new data it deletes the current data in the list and then adds the new data. I want it to keep all the data and just add data to the bottom of the listView. All of these classes are in the same Activity. Here is my current code.
class CreateCommentLists extends BaseAdapter{
Context ctx_invitation;
String[] listComments;
String[] listNumbers;
String[] listUsernames;
public CreateCommentLists(String[] comments, String[] usernames, String[] numbers, DashboardActivity context)
{
super();
ctx_invitation = context;
listComments = comments;
listNumbers = usernames;
listUsernames = numbers;
}
#Override

View v = null;
try
{
String inflater = Context.LAYOUT_INFLATER_SERVICE;
LayoutInflater li = (LayoutInflater)ctx_invitation.getSystemService(inflater);
v = li.inflate(R.layout.list_item, null);
TextView commentView = (TextView)v.findViewById(R.id.listComment);

public EndlessScrollListener() {

mainListView.smoothScrollToPosition(0);
}
}
#Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
}
}
mainListView.setOnScrollListener(new EndlessScrollListener());

You try this :
public class Comment {
String username;
String content;
String number;
}
Class Adapter:
public class CommentAdapter extends BaseAdapter {
private List<Comment> listComment;
private Context context;
public CommentAdapter(List<Comment> listComment, Context context) {
super();
this.listComment = listComment;
this.context = context;
}
#Override
public int getCount() {
return listComment.size();
}
#Override
public Comment getItem(int position) {
return listComment.get(position);
}
#Override
public long getItemId(int arg0) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = mInflater.inflate(R.layout.comment_item, null);
}
final TextView textViewUsername = (TextView) v
.findViewById(R.id.comment_Username);
final TextView textViewNumber = (TextView) v
.findViewById(R.id.comment_number);
final TextView textViewContent = (TextView) v
.findViewById(R.id.comment_Content);
final String username = listComment.get(position).getUsername();
final String number= listComment.get(position).getNumber();
String content = listComment.get(position).getContent();
textViewUsername.setText(username);
textViewNumber.setText(number);
textViewContent.setText(content);
return v;
}
}
When you need to add new comment to list. just create new Comment and add to listComment(listComment.add(newComment)), after that, call adapter.notifyDataSetChanged();

Android resource cannot be resolved to a variable

I am trying to Create a Array Adapter to set content from an Array of text to the adapter but i am not able to set the adapter from the Activity. Am not sure what i should pass for the resource as Int
PlacesListAdapter.java

Now in MainActiivty i am trying to set the adapter so that it populates the list from the Array
public class MainActivity extends SherlockFragmentActivity implements
SearchView.OnQueryTextListener {
private final String[] places = new String[] { "Mysore", "Bangalore", "Mangalore",
"Wayanad", "Bandipur National Park", "Chickmaglur",
"Bandipura", "Coorg", "Kodaikanal", "Hampi",
"Ghati Subramanya", "Mekedatu", "Muththathhi", "Shivasamudram",
"Talakadu", "Savana Durga" };
public SearchView mSearchView;
private TextView mStatusView;
private Menu mainMenu = null;
PlacesListAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.i("Nomad", "onCreate");
ListView listView = (ListView) findViewById(R.id.place_list);
adapter = new PlacesListAdapter(this, resource, places);
}
}
I am not sure what to set for resources in adapter = new PlacesListAdapter(this, resource, places);

Initialize the resource variable:
// it doesn't matter what values you assing to the resource variable because you build
// the row layout yourself in the getView method of the adapter
int resource = android.R.layout.simple_list_item_1;
adapter = new PlacesListAdapter(this, resource, places);
Edit:
List<Place> thePlaces = new ArrayList<Place>();
for (int i = 0; i < places.length; i++) {
Place pl = new Place("NO_ID", places[i], "NO_DISTANCE", "NO_CATEGORYICON");
thePlaces.add(pl);
}
int resource = android.R.layout.simple_list_item_1;
adapter = new PlacesListAdapter(this, resource, thePlaces);

pass row layout id instead of default android layout if your are creating custom adapter by extending ArrayAdapter:
adapter = new PlacesListAdapter(this,R.layout.item_place, places);
instead of
adapter = new PlacesListAdapter(this, resource, places);
