How to set Title of images based on image select in android

How to set Title of images based on image select in android - java

I am developing an android app, where I am trying to implement one feature for Image gallary. Now, initially, I want to show some image url with their title name. I am using hashmap for mapping title with their image.I have the model class with two String fields url and title. But The problem is I am very new in the development field and now sure how to show the title based on image click. Here is my model Class
public class ImageModel implements Parcelable {
String name, url;
public ImageModel() {
}
protected ImageModel(Parcel in) {
name = in.readString();
url = in.readString();
}
public static final Creator<ImageModel> CREATOR = new Creator<ImageModel>() {
#Override
public ImageModel createFromParcel(Parcel in) {
return new ImageModel(in);
}
#Override
public ImageModel[] newArray(int size) {
return new ImageModel[size];
}
};
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(name);
dest.writeString(url);
}
}
Now the Main activity where I create a Hashmap with image and title to show those into views.
public class MainActivity extends AppCompatActivity {
GalleryAdapter mAdapter;
RecyclerView mRecyclerView;
ArrayList<ImageModel> data = new ArrayList<>();
ArrayList<HashMap<String, String>> arrayList = new ArrayList<>();
HashMap<String, String> h1 = new HashMap<>();
String[] imgUrls = {"https://images.unsplash.com/photo-1444090542259-0af8fa96557e?q=80&fm=jpg&w=1080&fit=max&s=4b703b77b42e067f949d14581f35019b",

String[] imgNames = {"name1","name2","name3"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
for (int i = 0; i < 3; i++) { //change size according to your size.
ImageModel imageModel = new ImageModel();
imageModel.setName(imgNames[i]);
imageModel.setUrl(imgUrls[i]);
data.add(imageModel);
}
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mRecyclerView = (RecyclerView) findViewById(R.id.list);
mRecyclerView.setLayoutManager(new GridLayoutManager(this, 3));
mRecyclerView.setHasFixedSize(true);
mAdapter = new GalleryAdapter(MainActivity.this, data);
mRecyclerView.setAdapter(mAdapter);
mRecyclerView.addOnItemTouchListener(new RecyclerItemClickListener(this,
new RecyclerItemClickListener.OnItemClickListener() {
#Override
public void onItemClick(View view, int position) {
Intent intent = new Intent(MainActivity.this, DetailActivity.class);
intent.putParcelableArrayListExtra("data", data);
intent.putExtra("pos", position);
startActivity(intent);
}
}));
}
}
GalleryAdapterCode
public class GalleryAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
Context context;
List<ImageModel> data = new ArrayList<>();
public GalleryAdapter(Context context, List<ImageModel> data) {
this.context = context;
this.data = data;
}
#Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
RecyclerView.ViewHolder viewHolder;
View v;
v = LayoutInflater.from(parent.getContext()).inflate(
R.layout.list_item, parent, false);
viewHolder = new MyItemHolder(v);
return viewHolder;
}
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
Glide.with(context).load(data.get(position).getUrl())
.thumbnail(0.5f)
.override(200,200)
.crossFade()
.diskCacheStrategy(DiskCacheStrategy.ALL)
.into(((MyItemHolder) holder).mImg);
((MyItemHolder) holder).mTextView.setText(data.get(position).getName());
}
#Override
public int getItemCount() {
return data.size();
}
public static class MyItemHolder extends RecyclerView.ViewHolder {
ImageView mImg;
TextView mTextView;
public MyItemHolder(View itemView) {
super(itemView);
mTextView = (TextView) itemView.findViewById(R.id.textView);
mImg = (ImageView) itemView.findViewById(R.id.item_img);
}
}
}
My XML Class for item list row is
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1">
<ImageView
android:id="#+id/item_img"
android:layout_width="match_parent"
android:layout_height="188dp"
android:adjustViewBounds="true"
android:background="#color/colorAccent"
android:contentDescription="#string/app_name"
android:scaleType="centerCrop"
android:src="#drawable/placeholder" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#7000"
android:orientation="vertical"
android:padding="10dp"
android:layout_alignBottom="#+id/item_img"
android:layout_alignParentStart="true">
<TextView
android:id="#+id/textView"
android:text="Headline"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#FFF"
android:textSize="15dp"
android:textStyle="normal|bold"
/>
</LinearLayout>
</RelativeLayout>

Create two String arrays one containing image urls and other names in MainActivity.
String[] imgUrls = {"url1","url2","url3"};
String[] imgNames = {"name1","name2","name3"};
Iterate over those arrays and create a list of the model class.
ArrayList<ImageModel> data = new ArrayList<ImageModel>();
for (int i = 0; i < 3; i++) { //change size according to your size.
ImageModel imageModel = new ImageModel();
imageModel.setName(imgNames[i]);
imageModel.setUrl(imgUrls[i]);
data.add(imageModel);
}
mAdapter = new GalleryAdapter(MainActivity.this, data);
mRecyclerView.setAdapter(mAdapter);
Add a TextView in your RecyclerView row layout R.layout.list_item.
In your adapter use this TextView to set name of image.
public static class MyItemHolder extends RecyclerView.ViewHolder {
ImageView mImg;
TextView mTextView;
public MyItemHolder(View itemView) {
super(itemView);
mTextView = (TextView) itemView.findViewById(R.id.item_textview);
mImg = (ImageView) itemView.findViewById(R.id.item_img);
}
}
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
Glide.with(context).load(data.get(position).getUrl())
.thumbnail(0.5f)
.override(200,200)
.crossFade()
.diskCacheStrategy(DiskCacheStrategy.ALL)
.into(((MyItemHolder) holder).mImg);
holder.mTextView.setText(data.get(position).getName());
}
Rest of your code will be the same.

Glide allows to load a Bitmap.
you can save Bitmap to file, and then just pass file path to another screen.
Here you can find detailed tutorial, how to store image to file with Glide library:
https://medium.com/#akshayranagujjar/how-to-save-image-to-storage-using-glide-in-android-fa26c842f212
And don't forget about storage permissions.

how to callback from fragment to activity With bottom sheet

Hey I'm doing filtering data on my project using bottom Sheet with view-pager and two fragments i can pass data from activity to view-pager adapter and get in fragment through constructor but how can i get data from fragment to activity using bottom-sheet
this is how i send data from activity
adapter = new PagerAdapters(this.getSupportFragmentManager(),
tabLayout.getTabCount(),_id);
and receive data with constructor in fragment
public Filterfragment(String _id) {
this._id = _id;
}
And I'm using recyclerview to show data like this
So how can i send id of the item to activity so i can reload my recyclerview data when the apply button click.

While Creating Adapter for your Spinner give custom layout instead of predefined one
Create xml named spinner_row.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/cust_view"
android:layout_width="match_parent"
android:textColor="#color/black"
android:textSize="12sp"
android:layout_height="36dp"
android:gravity="left|center_vertical"/>
Here you can change the color Text size and width and height of the Elements in the spinner by modifying this textview
Use it like this while creating Adapter
ArrayAdapter<String> adapter=new ArrayAdapter<String>(context, R.layout.spinner_row,yourlist);
The Last task is routine
spinner.setAdapter(adapter);
I hope this will help you.

How to implement Favorite Button to my BaseAdapter ListView?

I'm learning Android SDK and I need some advices.
I have custom ListView with BaseAdapter and I want to implement some new feature - Favorite Button.
What I want to do is, when I press the Favorite Button, ListItem goes to the beginning of the list, Favorite image change and all that stuff will be saved in the SharedPrefs.
Someone tell me what I need to do, to make it works?
my existing code:
row.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/layout_element_list"
>
<ImageView
android:id="#+id/icon"
android:layout_width="150dp"
android:padding="5dp"
android:layout_height="150dp"
android:layout_marginLeft="4px"
android:layout_marginRight="10px"
android:layout_marginTop="4px"
android:src="#drawable/radio" >
</ImageView>
<LinearLayout

android:layout_width="fill_parent"
android:layout_height="fill_parent">

android:paddingTop="20dp"
android:layout_gravity="center_vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

public RadioAdapter(Context context, ArrayList<RadioStation> myList) {
this.myList = myList;
this.context = context;

}
#Override
public int getCount() {
return myList.size();
}
#Override
public RadioStation getItem(int position) {
return myList.get(position);
}
#Override

public int imgResId;
//getters and setters
public static Comparator<RadioStation> comparatorByRadioName = new Comparator<RadioStation>()
{
#Override
public int compare(RadioStation radioStation, RadioStation radioStation2)
{
String name1 = radioStation.getTitle().toLowerCase();
String name2 = radioStation2.getTitle().toLowerCase();
return name1.compareTo(name2);
}
};
}
ActivityListView:
public class ActivityMenuList extends Activity implements AdapterView.OnItemClickListener
{
private ListView lvDetail;
private Context context = ActivityMenuList.this;
private ArrayList <RadioStation> myList = new ArrayList <RadioStation>();
private String[] names = new String[] { "one", "two", "three" };
private String[] descriptions = new String[] { "notset", "notset", "notset"};
private int[] images = new int[] { R.drawable.one, R.drawable.two, R.drawable.three };
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
getWindow().setBackgroundDrawableResource(R.drawable.bg1);
setContentView(R.layout.activity_menu_list);
lvDetail = (ListView) findViewById(R.id.list);
lvDetail.setOnItemClickListener(this);
getDataInList();
lvDetail.setAdapter(new RadioAdapter(context, myList));
}
private void getDataInList() {
for(int i=0;i<3;i++) {
RadioStation ld = new RadioStation();
ld.setTitle(names[i]);
ld.setDescription(descriptions[i]);
ld.setImgResId(images[i]);
myList.add(ld);
}
Collections.sort(myList, RadioStation.comparatorByRadioName);
}
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l)
{
String item = names[i];
Intent e = new Intent(ActivityMenuList.this, ActivityRadioStation.class);
Bundle data = new Bundle();
data.putString("radiostation",item);
e.putExtras(data);
startActivity(e);
}
}

That's a lot of changes you have to do. Let's start with the basic.
Add a boolean to your RadioStation for the favorite state.
public boolean isFavorite;
Next on your getView add the favorite button click listener(add its reference to the viewholder too, but let's keep it simple this time)
public class RadioAdapter extends BaseAdapter
{
ArrayList<RadioStation> myList = new ArrayList<RadioStation>();
LayoutInflater inflater;
Context context;
ListView mListview;
public RadioAdapter(Context context, ArrayList<RadioStation> myList, ListView list) {
this.myList = myList;
this.context = context;
mListView = list;
inflater = LayoutInflater.from(this.context);
}
#Override
public int getCount() {
return myList.size();
}
#Override
public RadioStation getItem(int position) {
return myList.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
MyViewHolder mViewHolder;
if(convertView == null) {
convertView = inflater.inflate(R.layout.activity_menu_row, null);
mViewHolder = new MyViewHolder();
convertView.setTag(mViewHolder);
} else {
mViewHolder = (MyViewHolder) convertView.getTag();
}
mViewHolder.tvTitle = detail(convertView, R.id.label, myList.get(position).getTitle());
mViewHolder.tvDesc = detail(convertView, R.id.label2, myList.get(position).getDescription());
mViewHolder.ivIcon = detail(convertView, R.id.icon, myList.get(position).getImgResId());
convertView.findViewById(R.id.favButton).setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View view)
{
myList.get(position).isFavorite=! myList.get(position).isFavorite;
//reorder mlist
notifyDataSetChanged();
//mListView. smoothscroll here
}
});
((ImageView) convertView.findViewById(R.id.favButton)).setImageResource(myList.get(position).isFavorite?R.drawable.favoriteOn:R.drawable.favoriteOff);
return convertView;
}
private TextView detail(View v, int resId, String text) {
TextView tv = (TextView) v.findViewById(resId);
tv.setText(text);
return tv;
}
private ImageView detail(View v, int resId, int icon) {
ImageView iv = (ImageView) v.findViewById(resId);
iv.setImageResource(icon); //
return iv;
}
private class MyViewHolder {
TextView tvTitle, tvDesc;
ImageView ivIcon;
}
}
I left commented what you should do on the listener. You should be able to continue from here.
When you create your adapter pass the list as the last parameter on the constructor.
Edited: Removed interface. No need to use it here.
