How to make expandable cardview childlist in recycle view by reusing the same layout

I want to make view by adding child list on android using cardview in recycleview.
i have made class to store these item and make arraylist on each parent of object if the object have child item, so i can differentiate if the list has child or not.
But i have difficulties to render the same layout to make the child list below the parent list. I am pragmatically make the layout one by one but it will be difficult to make that. So i want to render the same layout to my adapter when i want to make a child list whenever the object/class has arraylist of child list in that object.
this is my adapter right now

please help me to render my layout whenever i want to make a child list under my parent list so i can simplify my code above and not making the child layout programatically

Can not trigger on Click

Can not trigger on Click listener
I tried
setClickable(true);
but still not working
minimum sdk is 15
the code doesn't have xml file, i need to fix it programmatically
the complete code:
public class MainActivity extends AppCompatActivity {
private static char CHAR = 'a';
private Context context;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
context = this;
LinearLayout layout = new LinearLayout(this);
layout.setOrientation(LinearLayout.VERTICAL);
int rowNo = ROWS;
int colNo = (screenWidth().widthPixels * ROWS /screenWidth().heightPixels) ;
for (int i = 0; i < 5; i++) {
LinearLayout row = new LinearLayout(this);
row.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT, 1.0f));
for (int j = 0; j < 5; j++) {
String txt = String.valueOf(CHAR);
Cell cell = new Cell(this, txt, 50, 50);
cell.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
System.out.println("value is " + txt);
}
});
row.addView(cell);
CHAR += 1;
}
layout.addView(row);
}
setContentView(layout);
}
private class Cell extends LinearLayout{
public Cell(Context context, final String value, int width, int height) {
super(context);
LinearLayout.LayoutParams cellParams = new LinearLayout.LayoutParams(width, height);
setLayoutParams(cellParams);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
setBackground(getGradientDrawable());
}else{
setBackgroundDrawable(getGradientDrawable());
}
}
private GradientDrawable getGradientDrawable() {
GradientDrawable shape = new GradientDrawable();
shape.setShape(GradientDrawable.RECTANGLE);
shape.setColor(Color.TRANSPARENT);
shape.setStroke(2, Color.BLACK);
return shape;
}
}
}
so, why and how to fix it.
at clicking the associated text will be printed

Try onClickListener inside your loop
Cell cell = new Cell(this, txt, 50, 50);
cell.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
System.out.println("value is " + value);
}
});

You are setting a local variable that hides the instance member :
private void nextWordsQuestion() {
int inext; // remove this line
...
inext = r.nextInt(MAXWORDS);
...
setWordsQuestion();
...
}
Therefore setWordsQuestion, which uses the instance member, doesn't see the value you set in nextWordsQuestion.

When you assign a random value to inext, you are assigning it to a local variable, not the global one.
To fix, simply remove the local variable.
private void nextWordsQuestion() {
//int inext;
Random r;
r = new Random();
inext = r.nextInt(MAXWORDS);
if (inext_question < MAXTEMP) {
tmp[inext_question] = inext;
inext_question++;
setWordsQuestion();
return;
}

Android Application Button onclicklistener

Hi there i've been constructing this code for a week but i still cant get it to work. It has no errors but when i run it on the AVD it terminates suddenly.

Button low = (Button) findViewById(R.id.button2);
final ImageView pic = (ImageView) findViewById(R.id.imageView1);
low.setOnClickListener(new view.OnClickListener() {
public void onClick(View v) {
int resource = cardid[RandomNumber];
if(current < RandomNumber){
points = points + 1;
score.setText(points);
pic.setImageResource(resource);
}else{
score.setText("Game Over");
}
}
});
high.setOnClickListener(new View.OnClickListener() {
public void higher(View v) {
int resource = cardid[RandomNumber];
if(current > RandomNumber){
points = points + 1;
score.setText(points);
pic.setImageResource(resource);
}else{
score.setText("Game Over");
}
}
});
int resource = cardid[RandomNumber];
pic.setImageResource(resource);
current = RandomNumber;
}
}
I cant figure out where my problem is, kindly check out my code. THanks for any help

put this:
ImageView pic2 = (ImageView) findViewById(R.id.imageView1);
final TextView score = (TextView) findViewById(R.id.textView2);
in you onCreate method after the call setContentView(R.layout.activity_main);.
How should R.id.imageView1 assigned if the content is not specified like in your case?
ImageView pic2;
TextView score;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pic2 = (ImageView) findViewById(R.id.imageView1);

Android: service not running

I have a service:
import android.app.IntentService;
import android.content.Intent;
import android.os.CountDownTimer;
import android.widget.Button;
public class CustTimer extends IntentService {
int length;
long timeLeft;
Button button;
long endTime;
public CustTimer() {
super("CustTimer");
}
public CustTimer(int length, Button button) {
super("CustTimer");
this.length = length;
this.button = button;
this.endTime = System.currentTimeMillis() + length;
}
#Override
protected void onHandleIntent(Intent intent) {
// TODO Auto-generated method stub
new CountDownTimer(length, 1000) {
public void onTick(long millisUntilFinished) {
String min = String.valueOf(millisUntilFinished/60000 );
long re = millisUntilFinished%60000;
String secs = String.valueOf(re/1000);
button.setText(min + ":" + secs);
timeLeft = millisUntilFinished;
}
public void onFinish() {
//button.setText("done");
}
}.start();
}
}
and an activity which calls it, the onCreate method is:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final Intent intent = new Intent(this, CustTimer.class);
LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
LinearLayout l2 = new LinearLayout(this);
l2.setOrientation(LinearLayout.HORIZONTAL);
LinearLayout l3 = new LinearLayout(this);
l3.setOrientation(LinearLayout.HORIZONTAL);
LinearLayout l4 = new LinearLayout(this);
l4.setOrientation(LinearLayout.HORIZONTAL);
LinearLayout l5 = new LinearLayout(this);
l5.setOrientation(LinearLayout.HORIZONTAL);
LayoutParams hor = new LayoutParams(0, LayoutParams.MATCH_PARENT, 1f);
LayoutParams ver = new LayoutParams(LayoutParams.MATCH_PARENT, 0, 1f);
for (int i = 0; i < 16; i++){
buts[i] = new Button(this);
buts[i].setText(String.valueOf(i+1));
timerRun[i] = false;
}
for (int i = 0; i < 4; i++) {
l2.addView(buts[i], hor);
}
for (int i = 4; i < 8; i++) {
l3.addView(buts[i], hor);
}
for (int i = 8; i < 12; i++) {
l4.addView(buts[i], hor);
}
for (int i = 12; i < 16; i++) {
l5.addView(buts[i], hor);
}
for (int i = 0; i < 16; i++) {
final int j = i;
buts[i].setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
CustTimer t1 = new CustTimer(times[j], buts[j]);
timers[j] = t1;
startService(intent);
}
});
}
ll.addView(l2, ver);
ll.addView(l3, ver);
ll.addView(l4, ver);
ll.addView(l5, ver);
this.setContentView(ll);
}
My problem is that the startService() call doesn't return any errors however it wont run. just looking for some basic input on if i've missed anything important to do with services
edit:
manifest section is:
<service android:name="CustTimer"> </service>

There's an easier way to implement a simple timer:
private final Handler mHandler = new Handler();
private final Runnable mRunnable = new Runnable() {
#Override
public void run() {
// TODO: update button text, manipulate views, etc.
mHandler.postDelayed(mRunnable, 1000);
}
};
private void start() {
mHandler.postDelayed(mRunnable, 1000);
}
private void stop() {
mHandler.removeCallbacks(mRunnable);
}
