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

How to store id selected radiobutton from stepstone

I'm creating an app where I have radio group with three radio buttons. What I want is when I check the radio button I need to get the id value of that radio button and save it in array or database and then count the id value.
For example i have this radiogroup in 19 fragment. which is each radiobutton has id value. if the button selected, it will get the id and store it so i can count the selected id value.
this is the display of my stepperstone
My StepFragment
Bundle bundle = this.getArguments();
Log.d("##", "onCreateView: " + bundle.getInt(MyStepperAdapter.CURRENT_STEP_POSITION_KEY)) ;

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);
}
});

Android table row onClickListener

I am having some problems when trying to trigger events on table layout in Android. These are the codes I used to populate the table layout dynamically:
private void BuildTable() {
try {
DatabaseAdapter mDbHelper = new DatabaseAdapter(Category.this);
mDbHelper.open();
CategoryController cc = new CategoryController(mDbHelper.open());
Cursor mCur = mDb.rawQuery(cc.getAllCat(), null);
if (mCur.getCount() != 0) {
if (mCur.moveToFirst()) {
// Setting table header
TableRow row = new TableRow(this);
row.setLayoutParams(new TableLayout.LayoutParams(
TableLayout.LayoutParams.MATCH_PARENT,
TableLayout.LayoutParams.WRAP_CONTENT));
do {
int cols = mCur.getColumnCount();
row = new TableRow(this);
for (int j = 1; j < cols; j++) {
// Dynamically load data fetch from database
// into table layout
TextView tv = new TextView(this);
tv.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.WRAP_CONTENT));
tv.setPadding(5, 5, 10, 5);
tv.setGravity(Gravity.LEFT);
tv.setText(mCur.getString(j));
row.addView(tv);
row.setId(j);
}
row.setClickable(true);
row.setOnClickListener(tablerowOnClickListener);
table_layout.addView(row);
} while (mCur.moveToNext());
}
}
} catch (SQLException mSQLException) {
throw mSQLException;
}
}
And here is my table row onClickListener:
private OnClickListener tablerowOnClickListener = new OnClickListener() {
public void onClick(View v) {
//Highlight selected row
v.setBackgroundColor(getResources().getColor(android.R.color.holo_red_light));
final int k = v.getId();
Toast.makeText(Category.this, Integer.toString(k),
Toast.LENGTH_SHORT).show();
}
};
My problem is when I highlighted certain row and I select another row again, the previous highlighted row remains the same highlighted background color. I wonder how to solve it?
Thanks in advance.

Provided table_layout is in the same scope as tablerowOnClickListener, change the Listener as follows:
private OnClickListener tablerowOnClickListener = new OnClickListener()
{
public void onClick(View v)
{
//Highlight selected row
for (int i = 0; i < table_layout.getChildCount(); i++)
{
View row = table_layout.getChildAt(i);
if (row == v)
{
row.setBackgroundColor(getResources().getColor(android.R.color.holo_red_light));
}
else
{
//Change this to your normal background color.
row.setBackgroundColor(getResources().getColor(android.R.color.transparent));
}
}
//...
}
};

Adding textviews dynamically to relativelayout.

While I am adding textviews to relative layout, at the end of first line, the textview is going wrong.
as shown in below:
.
here is my code to diplay textviews.
public void showkeyword()
{
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout fl = (RelativeLayout)findViewById(R.id.key_layout);
fl.removeAllViews();
RelativeLayout.LayoutParams params ;
//TextView key = (TextView) inflater.inflate(R.layout.tag_keyword,null);
i = 0;
for(String s : alist)
{
TextView textview = (TextView) inflater.inflate(R.layout.tag_keyword,null);
textview.setText(s);
textview.setId(2000 + i);
if (i == 0) {
RelativeLayout.LayoutParams rlp2 = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
rlp2.addRule(RelativeLayout.ALIGN_PARENT_TOP);
rlp2.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
textview.setLayoutParams(rlp2);
fl.addView(textview);
} else {
RelativeLayout.LayoutParams rlp2 = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
// rlp2.addRule(RelativeLayout.ALIGN_BASELINE);
rlp2.setMargins(10,0, 10,0);
rlp2.addRule(RelativeLayout.RIGHT_OF, textview.getId() - 1);
textview.setLayoutParams(rlp2);
fl.addView(textview);
}
i++;
}
}
I wish to have something like this, sort of a tab implementation:

Hope the following code will help you out:
Functioning:
contactWrapper is a linear layout, we go on adding the textviews into these linear layouts one by one and before adding find whether the contactWrapper has space enough to put in the next TextView, if not a new linear layout is created and the textViews are added into it.
Take time analyzing the following code.
public void drawLayout() {
int counter = 0;
contactWrapperWidth = getResources().getDisplayMetrics().widthPixels;
contactWrapper.setOrientation(LinearLayout.VERTICAL);
// contact wrapper is a linear Layout
// use LinearLayout contactWrapper = (LinearLayout) mView
// .findViewById(R.id.yourLinearLayout);
currCounter = 0;
currWidth = 0;
isNewLine = false;
row[currCounter] = new LinearLayout(getActivity());
#SuppressWarnings("rawtypes")
Iterator it = button.iterator();
for (int i = 0; i < button.size(); i++) {
it.next();
row[currCounter].setLayoutParams(new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT));
currWidth += Integer
.parseInt(button.get(i).get("width").toString());
Log.i("Item width ", "i == "
+ button.get(i).get("width").toString());
// contactWrapper.getw
if (isNewLine) {
if (currWidth < contactWrapperWidth) {
row[currCounter]
.addView((View) button.get(i).get("button"));
if (!it.hasNext()) {
contactWrapper.addView(row[currCounter]);
} else {
if (contactWrapperWidth < (currWidth + Integer
.parseInt(button.get(i + 1).get("width")
.toString()))) {
isNewLine = true;
contactWrapper.addView(row[currCounter]);
currCounter += 1;
row[currCounter] = new LinearLayout(getActivity());
currWidth = 0;
} else {
isNewLine = false;
}
}
} else {
isNewLine = true;
contactWrapper.addView(row[currCounter]);
currCounter += 1;
row[currCounter] = new LinearLayout(getActivity());
currWidth = 0;
}
} else {
if (currWidth < contactWrapperWidth) {
if (!it.hasNext()) {
View view = (View) button.get(i).get("button");
row[currCounter].addView((View) button.get(i).get(
"button"));
contactWrapper.addView(row[currCounter]);
} else {
View view = (View) button.get(i).get("button");
row[currCounter].addView((View) button.get(i).get(
"button"));
if (contactWrapperWidth < (currWidth + Integer
.parseInt(button.get(i + 1).get("width")
.toString()))) {
isNewLine = true;
Logger.show(Log.INFO, "it.hasNext()",
"it.hasNext() contactWrapper");
contactWrapper.addView(row[currCounter]);
currCounter += 1;
row[currCounter] = new LinearLayout(getActivity());
currWidth = 0;
} else {
isNewLine = false;
}
}
} else {
isNewLine = true;
contactWrapper.addView(row[currCounter]);
currCounter += 1;
row[currCounter] = new LinearLayout(getActivity());
currWidth = 0;
}
}
counter++;
}
}

Finally I am able to remove that bug using idea by #kailas
Here I am posting my method:
public void showkeyword() {
int counter = 0;

int i = 0;
contactWrapper.removeAllViews();
// contact wrapper is a linear Layout
// use LinearLayout contactWrapper = (LinearLayout) mView
// .findViewById(R.id.yourLinearLayout);
int currCounter = 0;
int currWidth = 0;
boolean isNewLine = false;
boolean firstLine = true;
for(final String s : alist)
{
TextView textview = new TextView(this);
RelativeLayout.LayoutParams rlp1 = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
rlp1.setMargins(7, 5, 7, 0);
textview.setText(s);
textview.setId(2000 + i);
textview.setBackgroundColor(Color.DKGRAY);
textview.setTextColor(Color.CYAN);
textview.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
contactWrapper.removeView(v);
alist.remove(s);
}
});
int width = s.length()*15;
if((currWidth+width+150)<=screenWidth)
{
currWidth += width+10;
isNewLine = false;
currCounter++;
}
else{
currWidth = width+14;
firstLine = false ;
isNewLine = true;
currCounter=1;
}
if(i==0)
{ rlp1.addRule(RelativeLayout.ALIGN_START);
textview.setLayoutParams(rlp1);
contactWrapper.addView(textview);
}
else if(isNewLine){
rlp1.addRule(RelativeLayout.ALIGN_LEFT);
rlp1.addRule(RelativeLayout.BELOW,2000-1+i );
textview.setLayoutParams(rlp1);
contactWrapper.addView(textview);
}
else if(firstLine)
{
rlp1.addRule(RelativeLayout.RIGHT_OF,2000-1+i );
textview.setLayoutParams(rlp1);
contactWrapper.addView(textview);
}
else{
rlp1.addRule(RelativeLayout.RIGHT_OF,2000-1+i );
rlp1.addRule(RelativeLayout.BELOW,2000-currCounter+i );
textview.setLayoutParams(rlp1);
contactWrapper.addView(textview);
}
i++;
}
buttonparams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
buttonparams.addRule(RelativeLayout.ALIGN_BASELINE,2000-1+i);
Button clearbtn = new Button(this);
clearbtn.setText("clear");
// clearbtn.setBackgroundColor(Color.RED);
// clearbtn.setTextColor(Color.CYAN);
clearbtn.setLayoutParams(buttonparams);
clearbtn.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
contactWrapper.removeAllViews();
alist.clear();
}
});
contactWrapper.addView(clearbtn) ;
}

Try to remove
rlp2.addRule(RelativeLayout.ALIGN_PARENT_TOP);
rlp2.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
because the behavior you want is the default behavior.
Put Orientation horinzontal in the relative layout.

Try using a LinearLayout and a fixed height (using the dip unit) instead of WRAP_CONTENT

Try to put all the text you want in one String and then put all this text in only one TextView.
The best way is using StringBuilder to concat the text:
StringBuilder sb = new StringBuilder();
sb.append("str1");
sb.append("str2");
and then put the string in the textview
textview.setText(sb.toString());
