How to fetch data related to a clicked item in a recyclerView from room database to a new activity?

My app has a RawMaterialFragment that displays raw materials data in a recyclerView from room database.
I am trying to build a detail activity(MetrialItemView) to show up the details of an individual raw material by clicking or selecting the raw material from the recyclerView.
my problem is how to send the data from the adapter and how to receive the data in the MetrialItemView Activity and display it.
MaterialListAdapter:
public class MaterialListAdapter extends RecyclerView.Adapter<MaterialListAdapter.ViewHolder> {
private final LayoutInflater mInflater;
private FragmentRawMaterials mContext;
private List<RawMaterialsEntity> mMaterial; // Cached copy of Materials
RawMaterialsEntity mCurrent;
public MaterialListAdapter(FragmentRawMaterials context) {
mInflater = LayoutInflater.from(context.getActivity());
mContext = context;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = mInflater.inflate(R.layout.list_item, parent, false);
return new ViewHolder(itemView);
}
public class ViewHolder extends RecyclerView.ViewHolder {
private final TextView materialName;
private final TextView materialBrand;
private final TextView materialQuantity;
LinearLayout parentLayout;
private ViewHolder(View itemView) {
super(itemView);
materialName = itemView.findViewById(R.id.raw_material_name);
materialBrand = itemView.findViewById(R.id.raw_material_brand);
materialQuantity = itemView.findViewById(R.id.raw_material_quantity);
parentLayout = itemView.findViewById(R.id.parent_layout);
}
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
if (mMaterial != null) {
mCurrent = mMaterial.get(position);
holder.materialName.setText(mCurrent.getRawMaterialName());
holder.materialBrand.setText(mCurrent.getRawMaterialBrand());
holder.materialQuantity.setText(String.valueOf(mCurrent.getRawMaterialQuantity()));
} else {
// Covers the case of data not being ready yet.
holder.materialName.setText("Name NA");
holder.materialBrand.setText("Brand NA");
holder.materialQuantity.setText("Quantity NA");
}
holder.parentLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(mContext.getContext(), MaterialItemView.class);
mContext.startActivity(intent);
}
});
}
public void setMaterial(List<RawMaterialsEntity> materials){
mMaterial = materials;
notifyDataSetChanged();
}
// getItemCount() is called many times, and when it is first called,
// mWords has not been updated (means initially, it's null, and we can't return null).
#Override
public int getItemCount() {
if (mMaterial != null)
return mMaterial.size();
else return 0;
}
}
MaterialItemView:
public class MaterialItemView extends AppCompatActivity {
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.material_item_view);
}
}

each row of dataModel() must have ID and then use putExtra() whan clicked It happens
holder.parentLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(mContext.getContext(), MaterialItemView.class);
intent.putExtra("ID",mCurrent.getID());
mContext.startActivity(intent);
}
});
and use getIntent() in detailActivity
int id =getIntent().getIntExtra("ID",-1);
and then get a row data in detail activity from database(viewModel)by ID and parse it

Display corresponding details of user when selected from list

I have developed a screen where a no. of people from the database are displayed in a list view. I want to display the profile page of the selected person. So my question is how to bind each detail of the selected person like name, contact, etc. to the profile page which I have created? Will I have to call the getById API in the onItemClickListener?
Here's the edited code:-

return genieService.getAll();
}

if (genies == null) {
new ArrayList<Genie>(); // "THERE WAS AN ERROR"
} else {
progressBar.setVisibility(View.GONE);
Log.i("INFO", genies.get(0).name);
List<String> rows = genies.stream().map(genie -> getRow(genie)).collect(Collectors.toList());
genieAdapter=new GenieAdapter(getApplicationContext(),R.layout.genie_list, genies);
ListView list=(ListView)findViewById(R.id.listViewMain);
list.setAdapter(genieAdapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override

default:
break;
}

}
Call Setting custom dialog
private void ShowSetting() {
SettingDialog settingDialog = new SettingDialog(PlayActivity.this, R.layout.setting_dialog);
settingDialog.setTitle("Setting");
settingDialog.setSaveClickListener("Save", new SettingDialog.OnSettingDialogClickListener() {
#Override
public void onClick(SettingDialog sDialog) {
LogHelper.d("PlayActivity", " Save button ");
sDialog.dismiss();
}
});
settingDialog.show();
}
Setting custom dialog apear and i touch save button but it has no function.
Could you please help me?

Woa, i've just found solution
Mising : btnSave.setOnClickListener(this);

setOnClickListener on a TextView inside a Cardview

I'm having some trouble implementing a setOnClickListener on a TextView inside a Cardview.I use this Cardview to populate a recicleview.
I have tried setting up the listener in the onBindViewHolder,but i can't see the log.

Thank You!

Try to set onClickListener after setText on your onBindViewHolder.
Refer this.
holder.mTextView.setText(mValues.get(position));
holder.mTextView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.e("Click", "Effettuato");
}
});
As per your code change this.
holder.nomeUser.setText(fotoS.getUser());
holder.nomeUser.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.e("Click","Effettuato");
}
});
EDIT 1:
In your FotoViewHolder overRide this before settaImmagine function.
#Override
public String toString() {
return super.toString() + " '" + nomeUser.getText();
}

Use
in xml
<TextView
<-- other attributes -->
android:clickable="true"
/>
in Adapter
nomeUser= (TextView)view.findViewById(R.id.**id**);
and finally
holder.nomeUser.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.e("Click","Effettuato");
}
});

Inside your
class FotoViewHolder
nomUser.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.e("Click","Effettuato");
}
});
if you want to identify different nomUser ,you can get the adapter position by using this code
int pos = getAdapterPosition();

This is your TextView in your layout :
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="USERNAME"
android:id="#+id/userName"
android:textStyle="bold|italic"
android:paddingTop="4dp"
android:paddingLeft="2dp"
android:layout_below="#+id/linear"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
You don't have android:clickable="true" . Add android:clickable="true" to your required TextView
and in your onBindViewHolder add :
holder.nomeUser.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.e("Click","clicked");
}
});

First add below property in you parent(Means parent Linear-layout of your singleItem) of Single Item layout,
android:descendantFocusability="blocksDescendants"
and then try as below,
public void onBindViewHolder(final SeguitiFragment_FotoADP.FotoViewHolder holder,final int position)
{
SeguitiFragment_Foto fotoS = foto.get(position);
bind(position,fotoS);
}
now in your FotoViewHolder class make method as below,
public void bind(int pos, SeguitiFragment_Foto fotoS) {
nomeUser.setText(fotoS.getUser());
nomeUser.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.e("Click","Effettuato");
}
});
}

Code optimisation. (Architecture)

I'm making a quiz app. User has to finish the phrase shown on display and write the name of the car in the edittext, after pushing on button, if the answer right, edittext become green, if doesn't, become red. If all answers right (green), intent move on next activity.
The question is: how to optimize my code, I don't like how it's look like? If I decide to add some more options it wouldn't be readable.
public class MainActivity extends AppCompatActivity {
EditText et_one_one, et_one_two, et_one_three;
Button buttonCheck;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et_one_one = (EditText) findViewById(R.id.et_one_one);
et_one_two = (EditText) findViewById(R.id.et_one_two);
et_one_three = (EditText) findViewById(R.id.et_one_three);
buttonCheck = (Button) findViewById(R.id.buttonCheck);
buttonCheck.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
boolean allAnswersCorrect = true;
String t1 = et_one_one.getText().toString().toLowerCase();
String t2 = et_one_two.getText().toString().toLowerCase();
String t3 = et_one_three.getText().toString().toLowerCase();
if (t1.equals("maserati")){
et_one_one.setBackgroundColor(Color.GREEN);
}
else {
allAnswersCorrect = false;
et_one_one.setBackgroundColor(Color.RED);
}
if (t2.equals("mercedes")){
et_one_two.setBackgroundColor(Color.GREEN);
}
else{
allAnswersCorrect = false;
et_one_two.setBackgroundColor(Color.RED);
}
if (t3.equals("bmw")){
et_one_three.setBackgroundColor(Color.GREEN);
}
else{
allAnswersCorrect = false;
et_one_three.setBackgroundColor(Color.RED);
}
if(allAnswersCorrect) {
Intent intent = new Intent(MainActivity.this, SecondActivity.class);
startActivity(intent);
}
}
});
}
}

I would strongly suggest a nice library called Butterknife by JakeWharton :
http://jakewharton.github.io/butterknife/
In your case your code would look like this :
public class MainActivity extends AppCompatActivity {
#Bind(R.id.et_one_one) EditText et_one_one;
#Bind(R.id.et_one_two) EditText et_one_two;
#Bind(R.id.et_one_three) EditText et_one_three;
#Bind(R.id.buttonCheck) Button buttonCheck;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
...
}
#OnClick(R.id.submit)
public void submit(View view) {
// check code here
}
Also you can group all your edit texts in a group :
#Bind({ R.id.et_one_one, R.id.et_one_two, R.id.et_one_three })
List<EditText> nameViews;
And apply some setters or actions on them :
...
ButterKnife.apply(nameViews, LOWERCASE);
...
static final ButterKnife.Action<View> LOWERCASE= new ButterKnife.Action<View>() {
#Override public void apply(View view, int index) {
// TODO set the text of the view to lowercase and disable textview
}
};

You can use RecyclerView to implement this. With it, you can dynamically add as much EditText for cars as you want. The sample is shown as below:
In your Activity:
private RecyclerView mRecyclerView;
private RecyclerView.Adapter mAdapter;
private RecyclerView.LayoutManager mLayoutManager;
private String[] answerArray;
Button buttonCheck;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mRecyclerView.setHasFixedSize(true);
mLayoutManager = new LinearLayoutManager(this);
mRecyclerView.setLayoutManager(mLayoutManager);
answerArray = new String[]{
"maserati",
"mercedes",
"bmw"
... (you can add as much as you want)
}
buttonCheck = (Button) findViewById(R.id.buttonCheck);
}
For RecyclerView.Adapter
public class MyRecyclerAdapter extends RecyclerView.Adapter<MyRecyclerAdapter.ViewHolder> {
String[] mAnswerArray;
public static class ViewHolder extends RecyclerView.ViewHolder {
public EditText editText;
public ViewHolder(View v) {
super(v);
editText = (EditText) v.findViewById(R.id.editText);
}
}
public MyRecyclerAdapter(String[] answerArray) {
this.mAnswerArray = answerArray;
}
#Override
public void onBindViewHolder(final ViewHolder holder, final int position){
super.onBindViewHolder(holder, position);
final String answer = mAnswerArray.get(position);
if ( holder.editText.getText().toString().toLowerCase().equals(answer) ) {
holder.editText.setBackgroundColor(Color.GREEN);
} else {
holder.editText.setBackgroundColor(Color.RED);
}
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext())
.inflate(R.layout.my_list_item, parent, false);
ViewHolder vh = new ViewHolder(v);
return vh;
}
#Override
public int getItemCount() {
return mAnswerArray.size();
}
}
For "my_list_item.xml", you just need to put inside and as for the ButtonCheck you can also pass an array or flag into adapter to record the state of each answer (correct or wrong) in order to decide whether to go to SecondActivity.
