Approach to get values of a dynamically generated textView - android

I successfully created a dynamic TextView and a Button now when ever the button was clicked the value of a TextView changes.
But the problem is I have a final "submit button" outside a loop which should get the INDIVIDUAL values of each TextView and I cant think of a way how to do it can someone pls give me an approach for this thanks!. pls be nice..
code
Cursor citem= sdb.rawQuery("SELECT * FROM ITEM INNER JOIN CATEGORY ON item.categoryid = category.id where category.categoryname='"+fcat+"'", null);
ScrollView scrollView= new ScrollView(this);
LinearLayout mainLayout= new LinearLayout(this);
mainLayout.setOrientation(LinearLayout.VERTICAL);
Button border = new Button(this);
border.setId(Integer.parseInt(cuser.getString(cuser.getColumnIndex("id"))));;
border.setText("ORDER");
while (citem.moveToNext())
{
byte[] blob =citem.getBlob(citem.getColumnIndex("itemimage"));
int id = Integer.parseInt(citem.getString(citem.getColumnIndex("id")));
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.HORIZONTAL);
linearLayout.setTag(id);
int i;
ImageView iv = new ImageView(this);
iv.setId(id);
iv.setImageBitmap(dh.getPhoto(blob));
final TextView txtquantity = new TextView(this);
txtquantity.setId(id);
txtquantity.setText("0");
txtquantity.setTextSize(20);
final TextView txtprice = new TextView(this);
txtprice.setId(id);
txtprice.setText(citem.getString(citem.getColumnIndex("itemprice")));
txtprice.setTextSize(30);
ImageButton btn1 = new ImageButton(this);
btn1.setId(id);
final int id_ = btn1.getId();
btn1.setImageResource(R.drawable.ic_launcher);
btn1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
int i = 0;
i=Integer.parseInt((String) txtquantity.getText())+1;
txtquantity.setText(String.valueOf(i));
totalprice.setText(String.valueOf(Integer.parseInt(totalprice.getText().toString())+(Integer.parseInt(txtprice.getText().toString())*1)));
}
});
ImageButton btn2 = new ImageButton(this);
btn2.setId(id);
final int id2_ = btn2.getId();
btn2.setImageResource(R.drawable.ic_launcher);
btn2.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
if(Integer.parseInt((String)txtquantity.getText())<=0)
{
}
else
{
int i=0;
i= Integer.parseInt((String) txtquantity.getText())-1;
txtquantity.setText(String.valueOf(i));
totalprice.setText(String.valueOf(Integer.parseInt(totalprice.getText().toString())-(Integer.parseInt(txtprice.getText().toString())*1)));
}
}
});
linearLayout.addView(iv);
linearLayout.addView(txtprice);
linearLayout.addView(btn1);
linearLayout.addView(txtquantity);
linearLayout.addView(btn2);
mainLayout.addView(linearLayout);
}
mainLayout.addView(totalprice);
mainLayout.addView(border);
scrollView.addView(mainLayout);
setContentView(scrollView);

Not quite sure what problem you're having? If it's just reading all the TextViews you created in the loop, then you should just keep a list, and send it off for processing when you submit...
List<TextView> tv_list = new ArrayList<TextView>();
while(...){
//In loop..add your tv's
TextView some_tv = new TextView()
tv_list.add(some_tv);
...
}
//In the submit, send them off for processing...
private void process_tvs(List<TextView> tv_list){
for(TextView tv:tv_list){
//Assuming your tv's have numbers...
int val = Integer.valueOf(tv.getText().toString());
//do something....
}
}

Text out of text view

I am currently having a problem with Android application. I am using a table layout with some views in it. The problem is that it seems like the TextView does not wraps the text correctly. However, when I change swipe between fragments it just resizes and it fits as how its supposed to.
This is what is looks like in the first place when the onCreate function is called.
And this is how it looks when I swipe between fragments.
This is the method I used to set up the views inside the table.
private void initializeBookTable(final List<Book> bookList, View view, final Button modifyBtn, final Button deleteBtn)
{
//Get screen width
DisplayMetrics displaymetrics = new DisplayMetrics();
((Activity)getContext()).getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int screenWidth = displaymetrics.widthPixels;
TableLayout table = view.findViewById(R.id.book_tableLayout);
//Border for the text views
final GradientDrawable gd = new GradientDrawable();
gd.setColor(getResources().getColor(R.color.colorTeal));
gd.setCornerRadius(2);
gd.setStroke(2, 0xFF000000);
//Font for the text views
Typeface font = Typeface.create("casual",Typeface.BOLD);
//Header row
TableRow headerRow = new TableRow(this.getContext());
TableLayout.LayoutParams headerRowParams = new TableLayout.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT);
headerRowParams.setMargins(0,1,0,0);
headerRow.setLayoutParams(headerRowParams);
//Header name text view
TextView headerName = new TextView(this.getContext());
headerName.setText(getResources().getString(R.string.book_NAME));
headerName.setBackground(gd);
headerName.setPadding(20,0,20,0);
headerName.setTypeface(font);
headerName.setTextColor(Color.BLACK);
headerName.setMinWidth(screenWidth/4);
headerRow.addView(headerName);
//Header chapter text view
TextView headerChapter = new TextView(this.getContext());
headerChapter.setText(getResources().getString(R.string.book_CHAPTER));
headerChapter.setBackground(gd);
headerChapter.setPadding(20,0,20,0);
headerChapter.setTypeface(font);
headerChapter.setTextColor(Color.BLACK);
headerChapter.setMinWidth(screenWidth/4);
headerRow.addView(headerChapter);
//Header page text view
TextView headerPage = new TextView(this.getContext());
headerPage.setText(getResources().getString(R.string.book_PAGE));
headerPage.setBackground(gd);
headerPage.setPadding(20,0,20,0);
headerPage.setTypeface(font);
headerPage.setTextColor(Color.BLACK);
headerPage.setMinWidth(screenWidth/4);
headerRow.addView(headerPage);
//Header name text view
TextView headerStatus = new TextView(this.getContext());
headerStatus.setText(getResources().getString(R.string.book_STATUS));
headerStatus.setBackground(gd);
headerStatus.setPadding(20,0,20,0);
headerStatus.setTypeface(font);
headerStatus.setTextColor(Color.BLACK);
headerStatus.setMinWidth(screenWidth/4);
headerRow.addView(headerStatus);
//Add row to table
table.addView(headerRow);
for(int i = 0; i < bookList.size(); i++)
{
TableRow row = new TableRow(this.getContext());
//Set text views parameters
TableRow.LayoutParams textViewParams = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT);
textViewParams.setMargins(0,1,0,1);
row.setLayoutParams(textViewParams);
//Set text views parameters
TextView name = new TextView(this.getContext());
name.setText(bookList.get(i).getName());
name.setBackground(gd);
name.setPadding(20,0,20,0);
name.setLayoutParams(textViewParams);
TextView chapter = new TextView(this.getContext());
chapter.setText(bookList.get(i).getChapter());
chapter.setBackground(gd);
chapter.setPadding(20,0,20,0);
chapter.setLayoutParams(textViewParams);
TextView page = new TextView(this.getContext());
page.setText(bookList.get(i).getPage());
page.setBackground(gd);
page.setPadding(20,0,20,0);
page.setLayoutParams(textViewParams);
TextView status = new TextView(this.getContext());
status.setText(bookList.get(i).getStatus());
status.setBackground(gd);
status.setPadding(20,0,20,0);
status.setLayoutParams(textViewParams);
//Add text views to the row
row.addView(name);
row.addView(chapter);
row.addView(page);
row.addView(status);
row.setClickable(true);
//Click listener for each row
row.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
TableRow tableRow = (TableRow) view;
selectedRow = tableRow;
//If the row is already selected (in red) deselect it
TextView textViewCheck = (TextView) tableRow.getChildAt(0);
if(selection && textViewCheck.getText().toString().equals(selectedBook.getName()))
{
for(int i = 0; i < 4; i++)
{
TextView textView = (TextView) tableRow.getChildAt(i);
textView.setBackground(gd);
}
//Disable add and modify buttons when row is deselected
modifyBtn.setEnabled(false);
deleteBtn.setEnabled(false);
selection = false;
selectedBook = null;
}
//If the row is not in red check if there is already a selected row
else
{
if(selection)
{
String message = "Please select only one";
Toast.makeText(getContext(), message, LENGTH_SHORT).show();
}
else
{
for(int i = 0; i < 4; i++)
{
TextView textView = (TextView) tableRow.getChildAt(i);
textView.setBackgroundColor(Color.RED);
}
//Enable add and modify buttons when row is selected
modifyBtn.setEnabled(true);
deleteBtn.setEnabled(true);
TextView nameView = (TextView) tableRow.getChildAt(0);
selectedBook = storage.findBook(nameView.getText().toString());
selection = true;
}
}
}
});
//Set row parameters
TableRow.LayoutParams tableRowParams = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT);
tableRowParams.setMargins(0,1,0,1);
row.setLayoutParams(tableRowParams);
table.addView(row);
}
}
This is my onCreate
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState)
{
View view = inflater.inflate(R.layout.books_fragment,container,false);
storage = InternalStorage.getInstance(this.getContext());
final Button modifyBtn = view.findViewById(R.id.modifyBtn);
final Button deleteBtn = view.findViewById(R.id.deleteBtn);
//Disable modify and delete buttons
modifyBtn.setEnabled(false);
deleteBtn.setEnabled(false);
this.initializeBookTable(storage.getBookList(),view, modifyBtn, deleteBtn);
Button addBtn = view.findViewById(R.id.addBtn);
addBtn.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View view) {
Intent intent = new Intent(getActivity(), AddModifyBook.class);
startActivity(intent);
}
});
modifyBtn.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View view)
{
Intent intent = new Intent(getActivity(), AddModifyBook.class);
//Passing the selected book to the AddModifyBook activity
intent.putExtra("selectedBook",selectedBook);
startActivity(intent);
selectedBook = null;
selection = false;
}
});
final TableLayout table = view.findViewById(R.id.book_tableLayout);
deleteBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
storage.removeBook(selectedBook);
selectedBook = null;
selection = false;
modifyBtn.setEnabled(false);
deleteBtn.setEnabled(false);
table.removeView(selectedRow);
}
});
return view;
}
And for onResume I have the default.
Another thing that is happening is that if I just set the background of the name (the first column) with the gradient drawable gd then it works but If I set the rest background of the rest of the columns then I have the problem that I have already explained.
So apparently I have managed to solve the issue by using a gradient drawable for the name and a different gradient drawable for the other properties.

How can get dynamic button text from another dynamic button OnClickListener event

I want get second dynamic button text from another dynamic button OnClickListener event:
Here is define some dynamic buutons:
LinearLayout lv=(LinearLayout)findViewById(R.id.lv);
for (int k = 1; k <= str[0].length(); k++) {
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(100, 100);
btnTopEn = new Button(this);
btnTopEn.setId(k);
final int id_ = btnTopEn.getId();
btnTopEn.setText(" ");
lv.addView(btnTopEn, params);
btnTopEn = ((Button) findViewById(id_));
final Button finalBtnT = btnTopEn;
btnTopEn.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
finalBtnT.setText("");
}
});
}
Now I want text of second button from OnClickListener Event:
TableLayout layout = (TableLayout)findViewById(R.id.TableL);
String stt="RZCEADHPTAUJTSFR";
int l=0;
for (int f=0; f<=1; f++) {
TableRow tr = new TableRow(this);
for (int c=0; c<=7; c++) {
btnCEn = new Button (this);
String ss=(String.valueOf(stt.charAt(l)));
btnCEn.setText(ss);;
final Button finalBtnB = btnCEn;
btnCEn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
int m=2;
btnTopEn = ((Button) findViewById(m));
final Button finalBtnT = btnTopEn;
if (finalBtnT.getText().equals("")) {
String stGetText=finalBtnB.getText().toString();
finalBtnT.setText(stGetText);
break;
}
}
}
});
TableRow.LayoutParams lp = new TableRow.LayoutParams(100,100);
tr.addView(btnCEn, lp);
}
layout.addView(tr);
}
I wrote some code in OnClickListener event but none happen!
What is the value of str in the first loop ?
Also you are setting the text to a space .
btnTopEn.setText(" ");
And while checking you check for empty :
if (finalBtnT.getText().equals("")){
}
Try changing to
if (finalBtnT.getText().toString().trim().equals("")){
}

Cannot add View To the relative Layout

}
String res = String.valueOf(form.result(varin));

});
}
}
You are adding all the views to RelativeLayout layout. But i think u have'nt add layout view to any activity_display_fomula view.
get a viewgroup from activity_display_fomula and add your RelativeLayout layout to it..

how do i align image view left of button programically?

how do i align image view left of button programically? in this code below i genrate button and image view programicallybut image view is show below of buton how do i set right of button image view??
public class MainActivity1 extends Activity {
public static Bitmap yourSelectedImage = null;

ContentValues newCon = new ContentValues();
public static byte[] blob = null;
public static long reqId;

// button margins
paramsLO.setMargins(0, 0, 0, 0);
// button height/width *pixels*
paramsLO.height = 75;
paramsLO.width = 75;
btnLO.setOrientation(LinearLayout.VERTICAL);
btnLO.setBackgroundColor(5); // not working correctly
//buttons
for (i =0;i <j;i++)
{
final Button b1 = new Button(MainActivity1.this);
final ImageView imageView = new ImageView(MainActivity1.this);
b1.setText(reqdata[i].getSpinnerText());
b1.setTag(reqdata[i].getValue());
btnLO.addView(b1, paramsLO);
btnLO.addView(imageView, paramsLO);
b1.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
reqId =
Long.valueOf(reqdata[btnLO.indexOfChild(b1)/2].getValue()).longValue();
Toast.makeText(MainActivity1.this, reqId+"",
Toast.LENGTH_SHORT).show();
}
final Button b2 = new Button(MainActivity1.this);
b2.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
}
});
btnLO.addView(b2, paramsLO);
btnLO.setGravity(Gravity.LEFT | Gravity.CENTER_HORIZONTAL);
this.addContentView(btnLO, new LayoutParams());
}
LinearLayout li=new LinearLayout(this);
li.setOrientation(LinearLayout.HORIZONTAL);
final Button b1 = new Button(MainActivity1.this);
final ImageView imageView = new ImageView(MainActivity1.this);
b1.setText(reqdata[i].getSpinnerText());
b1.setTag(reqdata[i].getValue());
li.addView(b1, paramsLO);
li.addView(imageView, paramsLO);
btnLO.addView(li);
ScrollView sc=new ScrollView(this);
sc.addView(btnLO);
remember this must be done outside for loop.
this is how you need to add button and image to your layout inside for loop

refresh activity with dynamic content

I have an activity with some dynamic content.
For each item of an array, there is a different content (number of textViews, checkboxes, ..)
The user clicks on a "save" button and then the screen has to refresh itself to display the content of the next item.
I was wondering if it was a good practice to reload my activity like this :
Intent refresh = new Intent(this, conflictActivity.class);
startActivity(refresh)
finish()
instead of removing all the views in my layouts, etc ...
I think it's easier to reload it.
Is there another way to do it ?
EDIT : added Code.

Sorry for the code, it is a litle bit dirty (i have deleted some parts), i am reworking it.
int flag = 0;
public void updateUI() {
if(flag == 0) {
//your normal codes...
} else {
//display view with user given data
}
}
Call this function in oncreate. At first flag will be set to zero. When u enter the data in textview and tick checkboxes, update the flag with some value. Then on save Button click call this function again. Now flag is set. So it will display the updated UI.
I think this will give u an idea..
