Android : How to set ID's for every single items in list of arrays of card view and be clickable?

Hye... I'm new in android development and i'm facing a little bit problem on the android project that I'm in right now. The codes below successfully returning the list of items on the activity_ticket_info.xml layout. Since the number of items appeared based on the looping process, how to set an ID on every single items that appeared so afterwards it could be set as clickable items to intent to another activity layout? Please help me to figure this out. Thanks a lot for the help..

**UPDATED : I'm trying to implement a switch case statement as above for every single items that need to be navigated to each fragment layout and there is no errors found at all but it doesn't work. Could the above switch case statement be the proper way to navigate each items or there is another better way to implement? **

If you want to use it later as clickable, instead of assigning the id, you can set the listener for each item when they are returned and call the intent.
However if you still want to assign id, you can use method setId(int) which is available for all types of widgets.. and views

if you want to just make clickable your every cardview item you can make interface
public interface ItemClickListener {
void onItemClick(View v, int pos);
}
and implement this on you adapter class like this
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder>{
private List<Model> list;
Context mContext;
public MyAdapter(Context context,List<Model> list) {
mContext=context;
this.list = list;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.card_view, parent, false);
return new MyViewHolder(itemView);
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
final Model model = list.get(position);
holder.name.setText("name :"+model.getName());
holder.setItemClickListener(new ItemClickListener() {
#Override
public void onItemClick(View v, int position) {
Snackbar.make(v,list.get(position).getName(),Snackbar.LENGTH_SHORT).show();
Intent i=new Intent(mContext, Showname.class);
mContext.startActivity(i);
}
});
}
#Override
public int getItemCount() {
return list.size();
}
public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener
{
public TextView name,branch,sem;
ItemClickListener itemClickListener;
public MyViewHolder(View itemView) {
super(itemView);
name = (TextView)itemView.findViewById(R.id.s_name);
itemView.setOnClickListener(this);
}
#Override
public void onClick(View v) {
this.itemClickListener.onItemClick(v,getLayoutPosition());
}
public void setItemClickListener(ItemClickListener ic)
{
this.itemClickListener=ic;
}
}
}

I think there is no such method to provide ID for each item dynamically.According to the program above you can select only a single item in the recyclerView at a time. Better create a method in main activity as below
public void setRVAdapterSelectedItem(String itemName){this.itemName = itemName;}
and set the clicked string to activity by calling from onClick of the adapter
context.setRVAdapterSelectedItem(selectedString);
So that you will get the list in Activity.
It is always better to use a model class for item list. Hence you can use a boolean to identify if the item is selected or not and using that you can highlight item in onBindViewHolder

Radio Buttons Deselected on scrolling in custom listview
i have made custom listview that add
run time radiobutton added autimatically
but it deselected on scroll

This is a very common problem in Android with Listviews and Radio buttons.
First, I would recommend you to check this post:
Using radio button in custom listview in Android
Now, I'm going to tell you which solution fits for me. In my case I use GridView, but it also works for ListView.
In your Adapter's class you have to have a variable for the selected item and his index, it could be something like:
private int mSelectedPosition = -1;
private RadioButton mSelectedRB;
Then, define a function to retrieve this information:
public int getItemSelected(){
return mSelectedPosition;
}
Now, In order to make it works properly, you have to user a ViewHolder (in my case every item in the GridView has a Image and a RadioButton), so you define your ViewHolder in the Adapter's class as well:
private class ViewHolder {
ImageView image;
RadioButton radio;
}
Then, in your getView function, you have to work with the ViewHolder. In the code I write comments to follow.
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView; // assign the view
ViewHolder holder; // declare the ViewHolder
if(view == null){
// cutom layout for each row (item) of the ListView
view = mLayoutInflater.inflate(R.layout.item_list_company, parent, false);
holder = new ViewHolder();
// initialize the ViewHolder's field
holder.image = (ImageView) view.findViewById(R.id.c1);
holder.radio = (RadioButton)view.findViewById(R.id.cN1);
view.setTag(holder); // set the tag
}else{ // already initialized
holder = (ViewHolder)view.getTag(); // so we only set the tag
}
// on click triggered for each RadioButton in the ListView
holder.radio.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(position != mSelectedPosition && mSelectedRB != null){
mSelectedRB.setChecked(false); // uncheck the last one
}
mSelectedPosition = position; // change the item selected index
mSelectedRB = (RadioButton)v; // assign the new item selected
}
});
// just to control the right item checked
if(mSelectedPosition != position){
holder.radio.setChecked(false);
}else{
holder.radio.setChecked(true);
if(mSelectedRB != null && holder.radio != mSelectedRB){
mSelectedRB = holder.radio;
}
}
return view;
}
Finally, in the custom layout (item_list_company.xml in my case) for each item in the ListView, I have the following code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent">
<ImageView android:id="#+id/c1"
android:layout_width="wrap_content"
android:layout_height="100dp"
android:layout_gravity="center"
android:scaleType="centerInside" />
<RadioButton
android:id="#+id/cN1"
android:layout_width="wrap_content"
android:layout_height="50dp"
android:buttonTint="#color/colorPrimary"
android:textColor="#color/colorAccent"
android:focusable="false"
android:layout_gravity="left"
android:clickable="false"
android:focusableInTouchMode="false"
android:textSize="20dp"/>
</LinearLayout>
Special attention for this three attributes of the RadioButton:
android:focusable="false"
android:clickable="false"
android:focusableInTouchMode="false"
So, with all of this, you only have to set your adapter and ListView in your Activity and call to the right function to retrieve the selected item:
ArrayList<MyBean> arrayList = new ArrayList<>();
ListView listView1 = (ListView)findViewById(R.id.llv);
Adpt adpt = new Adpt(getApplicationContext(), arrayList);
// add data to the ArrayList
adpt.notifyDataSetChanged(); // notify for the new data in the ArrayList
// retrieve the item selected
int selected = adpt.getItemSelected();
Hope it helps!

Well, if i click in ImageView, it fire the event click and the listener capture it, but if i click in CheckBox the event click don't fire.
What I doing wrong? What I need to do?
Thanks in advance.

android:focusableInTouchMode="false" android:focusable="false"

#Sam is right, checkboxes handle clicks on their own and the click event never reaches the AdapterView.
Now, technically speaking, you could set android:clickable="false" for your checkbox in the layout file, and then the click event would get delivered up the view hierarchy, but in this case you won't be able to do anything useful with the checkbox, it will just always stay unchecked.
Here's what would be a better approach. Move the "do something" into a different method and add another onClickListener for the checkbox, to do the same thing:
gridViewImagenes.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
doSomething();
}
});
myCheckbox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
doSomething();
}
});
}
private void doSomething() {
//Do Stuff
}

Think you will have to implement a OnCheckedChangelistener to the checkbox, in your case to chkItem.
See CompoundButton.OnCheckedChangeListener
The implementation would be something like...
CheckBox checkBox = (CheckBox) findViewById(R.id.chkItem);
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(isChecked) {
// checkbox is checked - doSomething()
} else {
// checkbox is unchecked
}
}
});
Hope this helps.

I finally decided to put the adapter into the Activity class. In Class Adapter put a listener both ImageView and CheckBox component, since these listener invoking a method of the Activity class.
Thanks to all for your time and response!!!

return convertView;
}

}

when I need check boxes inside listview, I often code as following:
MyAdapter.java:
- Declare an boolean array to mark which item is checked/unchecked:
....
boolean[] checked;
...
inside constructor:
checked = new boolean[data.size()];
- Inside getView()
{
.....
holder.items_check.setChecked(checked[position]);
holder.items_check.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
checked[position] = isChecked;
}
});
.....
- And method to get all checked items:
boolean[] getCheckedItems() {
return checked;
}
That's !

Could it be that your getItem and getItemId only return null and 1? These methods need to return the correct data for this to work I believe. getItem would need to be:
String getItem(int position)
{
return data.get(position);
}
and getItemId would simply return position instead of 0:
String getItemId(int position)
{
return position;
}

need tutorials on Android Custom-List

last days I was browsing one of the apps in Android
and I found out an amazing list.
I Found that Custom ListView Interesting.
When we click on the Text it shows me some Activity and when we click on the Arrow on Right it shows me a dialog.
I want to learn this. Can anybody go through some Tutorials where this Custom List is explained. Please Friends. guide me.. Thanks alot

Hi Below Is Custom ListView Example
First Create test.Java File below is code
package com.test;
import java.util.ArrayList;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ListView;
public class test extends Activity {
/** Called when the activity is first created. */
ArrayList<String> arrayString = new ArrayList<String>();
test_adapter adapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
arrayString.add("TextView1");
arrayString.add("TextView2");
arrayString.add("TextView3");
arrayString.add("TextView4");
arrayString.add("TextView5");
ListView list = (ListView) findViewById(R.id.LIST);
adapter = new test_adapter(this, arrayString);
list.setAdapter(adapter);
}
}
Also Used below Class file test_adapter.java
package com.test;
import java.util.ArrayList;
import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.RelativeLayout;
import android.widget.TextView;
import android.widget.Toast;
public class test_adapter extends BaseAdapter {
private Activity activity;
ArrayList<String> data = new ArrayList<String>();
private static LayoutInflater inflater = null;
public test_adapter(Activity a, ArrayList<String> d) {
activity = a;
data = d;
inflater = LayoutInflater.from(activity);
}
public int getCount() {
return data.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public static class ViewHolder {
public TextView txt1;
public Button btn1;
public RelativeLayout rel1;
}
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
final ViewHolder holder;
if (convertView == null) {
vi = inflater.inflate(R.layout.listview, null);
holder = new ViewHolder();
holder.txt1 = (TextView) vi.findViewById(R.id.txt1);
holder.btn1 = (Button) vi.findViewById(R.id.btn1);
holder.rel1 = (RelativeLayout) vi.findViewById(R.id.rel1);
vi.setTag(holder);
} else
holder = (ViewHolder) vi.getTag();
holder.txt1.setText(data.get(position));
holder.rel1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast
.makeText(activity, "Click On TextView",
Toast.LENGTH_LONG).show();
}
});
holder.btn1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(activity, "Click On Button", Toast.LENGTH_LONG)
.show();
}
});
return vi;
}
}
Used below layout files main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<ListView android:layout_width="fill_parent" android:id="#+id/LIST"
android:layout_height="fill_parent" />
</LinearLayout>
Used listview.xml file
<?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:orientation="horizontal">
<RelativeLayout android:id="#+id/rel1" android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content" android:id="#+id/txt1"
android:text="Test Description"></TextView>
</RelativeLayout>
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button android:id="#+id/btn1" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="ClickHere"
android:layout_alignParentRight="true"></Button>
</RelativeLayout>
</LinearLayout>
Used Above Code and you will get display toast message and you can changed as per you requirement.
