I can't set the button width inside the table view

I'm doing an android application where I have to dynamically put a button inside the table row. The problem is that the button that I create is stretched as in the image below:
I also put some of the application code here below so you can understand better.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_punteggio);
showAlertDialog_modality(R.layout.dialog_change_modality);
final TableLayout tableLayout = findViewById(R.id.tableLayout);
final RelativeLayout relativeLayout = findViewById(R.id.relativeLayout);
final Button btn_settings = findViewById(R.id.btn_settings);
Bundle datipassati = getIntent().getExtras();
String player = datipassati.getString("players");
giocatore = player.split("%");
Log.d("TAG", "array: " + giocatore[0]);
for (int i = 0; i < giocatore.length; i++) {
punti[i] = 0;
TableRow tbrow = new TableRow(this);
final TextView t3v = new TextView(this);
txPunti[i] = t3v;
//------------------------- Textview Player
final TextView t1v = new TextView(this);
t1v.setText(giocatore[i].toUpperCase());
t1v.setTextColor(Color.BLACK);
t1v.setGravity(Gravity.CENTER);
t1v.setTextSize(20);
t1v.setWidth(400);
tbrow.addView(t1v);
//-------------------- BTN MENO
Button btnMeno = new Button(this);
btnMeno.setText("-");
btnMeno.setTextColor(Color.BLACK);
btnMeno.setGravity(Gravity.CENTER);
tbrow.addView(btnMeno);
btnMeno.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
removepoint(t3v);
}
});
// --------------------- TEXT VIEW PUNTI
t3v.setText(punti[i]+"");
t3v.setTextSize(25);
t3v.setMaxWidth(150);
t3v.setPadding(20,0,20,0);
t3v.setTypeface(t3v.getTypeface(), Typeface.BOLD);
t3v.setTextColor(Color.RED);
t3v.setGravity(Gravity.CENTER);
tbrow.addView(t3v);
//----------------------------- BTN PIU
Button btnPiu = new Button(this);
btnPiu.setBackground(ContextCompat.getDrawable(Activity_punteggio.this, R.drawable.ic_add_circle_black_24dp));
btnPiu.setTextColor(Color.BLACK);
btnPiu.setGravity(Gravity.CENTER);
tbrow.addView(btnPiu);
btnPiu.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
addPoint(t3v, t1v);
}
});
tableLayout.addView(tbrow);
}
btn_settings.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
showAlertDialog_modality(R.layout.dialog_change_modality);
}
});
}
Here's also the xml file:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/relativeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".Activity_punteggio">
<Button
android:id="#+id/btn_settings"
android:layout_width="55dp"
android:layout_height="32dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginTop="0dp"
android:layout_marginRight="1dp"
android:background="#android:color/transparent"
android:drawableBottom="#drawable/ic_settings_black_24dp" />
<TextView
android:id="#+id/title_player"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="20dp"
android:text="Chip-Chop"
android:textSize="25dp"
android:textStyle="bold|italic" />
<TableLayout
android:id="#+id/tableLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="80dp">
</TableLayout>
</RelativeLayout>
I hope you could help me.

Please check this solution. setImageResource is the method assign
image resource. Set background method is recommended for the
background of the button.
ImageButton btnPiu = new ImageButton(this);
btnPiu.setImageDrawable(ContextCompat.getDrawable(Activity_punteggio.this, R.drawable.ic_add_circle_black_24dp));
btnPiu.setTextColor(Color.BLACK);
btnPiu.setGravity(Gravity.CENTER);
tbrow.addView(btnPiu);
btnPiu.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
addPoint(t3v, t1v);
}
});
tableLayout.addView(tbrow);
I used ImageButton other than Button.
setImageDrawable

try to edit android:layout_height="32dp" to android:layout_height="55dp"
android:id="#+id/btn_settings"
android:layout_width="55dp"
android:layout_height="55dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginTop="0dp"
android:layout_marginRight="1dp"
android:background="#android:color/transparent"
android:drawableBottom="#drawable/ic_settings_black_24dp" />
I hope it will work with you .

THIS is make very complex coding, Make it simpler.Don't create whole row dynamically in FOR loop. Instead of that
First Create Separate XML for that row.
Write Below code and your row append into tablelayout.
for (int i = 0; i < giocatore.length; i++) {
View trView = LayoutInflater.from(getActivity()).inflate(R.layout.xmlID,null);
TextView lblGuestName;
lblGuestName = trView.findViewById(R.id.lbl);
lblGuestName.setText("Guest 1");
tableLayout.addView(trView);
}
This Way you easily configure any complex row in tablelayout. No need to make it dynamically.

How to Display Data to Listview from SharedPreferences

I have two activity (DetailProduct and Wishlist) and i want to display data from DetailProduct to Wishlist, in here i using SharedPreferences for put data from DetailProduct to Wishlist.
This is my activity DetailProduct
wishlist.setOnClickListener(new View.OnClickListener() {
String imgpicaso = getIntent().getStringExtra("aaa");
String vardetailed = getIntent().getStringExtra("acb");
String thisname = getIntent().getStringExtra("name");
String text = getIntent().getStringExtra("abb");
#Override
public void onClick(View view) {
Intent tambah = new Intent(DetailProduct.this, Wishlist.class);
SharedPreferences sharedPreferences = DetailProduct.this.getSharedPreferences("baba", MODE_PRIVATE);
SharedPreferences.Editor shreditor = sharedPreferences.edit();
shreditor.putString("aaa", imgpicaso);
shreditor.putString("name", thisname);
shreditor.putString("abb", text);
shreditor.commit();
startActivity(tambah);
}
});
This is img DetailProduct
This is img Wishlist, please open this img
And this is file Wishlist.java
protected void onCreate(Bundle savedInstanceState) {

String imgpicaso = sharedPreferences.getString("aaa", "");
Picasso.with(getBaseContext()).load(imgpicaso).into(resultgmb);
String detailtext = sharedPreferences.getString("name", "");
detailtok.setText(detailtext);
String text = sharedPreferences.getString("ccc", "");
resulttext.setText("$: " +text);
listproduct = (ListView) findViewById(R.id.listproduct);

Please help me, thank you

As #sark9012 pointed out, you might want to use Intent Data rather than shared preferences for that purpose. Here is a tutorial on that.
Edit
Although I'd really advise against using Shared Preferences data for the purpose you're looking for, it seems you got the code correct for retrieving the data from the Shared Preferences, what you might be missing out on is populating the ListView. This is the code you sent us:
listproduct = (ListView) findViewById(R.id.listproduct);
ArrayList<String> arrayList = new ArrayList<>();
ArrayAdapter<String> arr = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1);
listproduct.setAdapter(arr);
arr.notifyDataSetChanged();
I don't really see you populating the adapter with the data retrieved, so you might want to have a look into that. Check this example from CodePath on how to setup the ListView with an ArrayAdapter.

Generate comma separated string and store that in shared preference
while storing to SP.
like string1 = a1+","a2+","a3;
while retrieving from SP.
like array[] = string1.split(",");
ArrayAdapter adapter = new ArrayAdapter(this,
android.R.layout.simple_list_item_1, array);

How to add jsonarray response in linear layout?

I am getting a json response in which i am getting jsonObject and jsonArray. I successfully set values for jsonObject but for JsonArray i have two values for each as que ans ans. for example:
"question": [
{
"ans": "test",
"que": "What is your name"
},
{
"ans": "25-30",
"que": "Age"
}
]
this is jsonarray in jsonObject. Now i want to set que and ans in textbox. Note that number of questions are not fixed, they can be 12 or more or less depends on API.
My question is how to set this questions in layout inflater or anything like that?
thanks in advance :)

You will need to use inflation like this: Keep one item.xml which will hold 2 TextViews (or EditText as per your need.)
item.xml:
<RelativeLayout
android:id="#+id/item_row"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/que"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true" />
<TextView
android:id="#+id/ans"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true" />
</RelativeLayout>
Now in your code:
You would need to inflate that item.xml in a loop for as many items you get in your JSONArray. So firstly parse JSONArray and get a ArrayList of Question, Answer pair:
ArrayList<String[]> myArr = new ArrayList<String[]>();
for (int i=0; i < myJSONArray.length(); i++) {
JSONObject j = myJSONArray.getJSONObject(i);
String[] t = {j.getString("que"),j.getString("ans")};
myArr.add[t];
}
Pass this to your activity.
Now you would need to iterate through the ArrayList and inflate your layout, populate TextViews with values in map, and add the inflated view in parent layout:
RelativeLayout container = (RelativeLayout)findViewById(R.id.mylayout); //this will be your container layout
for (int i = 0; i < secQAArr.size(); i++){
View item = getLayoutInflater().inflate(R.layout.item, null);
TextView tQue = (TextView) findViewById(R.id.que);
que.seText(secQAArr.get(i)[0]);
TextView tAns = (TextView) findViewById(R.id.ans);
que.seText(secQAArr.get(i)[1]);
container.addView(item);
}
Hope it helps.

Try this way,hope this will help you to solve your problem.

How to keep both components from XML and those added programatically

I am new to Android.
I am drawing Textfield using drag-drop from Eclipse.
Also adding a Table programatically.
But I can see only table which is added programatically.
How to keep both components from XML and those added programatically.
Sorry if it is a really basic and stupid question.
Here is my code
<?xml version="1.0" encoding="utf-8"?>
<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/tableLayout1"
android:layout_width="match_parent"

android:layout_height="wrap_content"
android:ems="10" >
<requestFocus />
</EditText>
<ZoomButton

</TableLayout>
and
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
DatabaseHandler db = new DatabaseHandler(this);
//To insert
// db.addContact(new Contact("Ninad", "9893353432"));
TableLayout table = new TableLayout(this);
table.setStretchAllColumns(true);
table.setShrinkAllColumns(true);
TableRow rowTitle = new TableRow(this);
rowTitle.setGravity(Gravity.CENTER_HORIZONTAL);
TableRow rowDayLabels = new TableRow(this);
// title column/row
TextView title = new TextView(this);
title.setText("Contacts");
title.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 18);
title.setGravity(Gravity.CENTER);
title.setTypeface(Typeface.SERIF, Typeface.BOLD);
TableRow.LayoutParams params = new TableRow.LayoutParams();
params.span = 3;
rowTitle.addView(title, params);
// Header 1
TextView header1 = new TextView(this);
header1.setText("ID");
header1.setTypeface(Typeface.SERIF, Typeface.BOLD);
rowDayLabels.addView(header1);
// Header 2
TextView header2 = new TextView(this);
header2.setText("NAME");
header2.setTypeface(Typeface.SERIF, Typeface.BOLD);
rowDayLabels.addView(header2);
// Header 3
TextView header3 = new TextView(this);
header3.setText("PHONE");
header3.setTypeface(Typeface.SERIF, Typeface.BOLD);
rowDayLabels.addView(header3);
// Add to Table
table.addView(rowTitle);
table.addView(rowDayLabels);
List<Contact> contacts = db.getAllContacts();

TextView day3High = new TextView(this);
day3High.setText(cn.getPhoneNumber());
rowHighs.addView(day3High);
table.addView(rowHighs);
}
setContentView(table);
}
My Table in the OnCreate method is populated properly, but components from XML are lost.
Update :
What I found is, I am setting it two times and later one is overwritting it
setContentView(R.layout.activity_main);
setContentView(table);
But how can I merge it ?

Type in your activity below oncreate
TableLayout tbl_lay=(TableLayout)findViewById(R.id.tablelayout1);
.....
.....
.....
Your Code.....
TableLayout tb=new TableLayout(this);
.....
.....
atlast add these line
tbl_lay.addview(tb);
it will help you

Your layout name is "tableLayout1" in xml, you should implement a TableLayout object from it by using findViewById, and add your programmatically created view to it. Be careful about positioning, you may put it on your drag-drop views!
TableLayout myLayout = (TableLayout) findViewById(R.id.tableLayout1);
//your elements created
myLayout.addView(yourCreatedViewElement);

How do I add a TextView to the current layout so I can populate my spinners?

Here is the layout I am trying to get. As long as I don't actually try to populate my spinners, everything loads just fine. Based on what I have found in my searches and the log is that I need to use a TextView with the ArrayAdapter. Exactly how I do that while preserving the current layout - Spinners and a submit button at the top with a ListView for the returned results below the spinners is what I am having trouble achieving.
Here is my onCreate method.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.master);
DBHelper db = new DBHelper(this);
List<Stations> st = db.getAllStations();
List<CharSequence> stations = new ArrayList<CharSequence>();
setList(4, 9);
for (int i = 0; i < st.size(); i++)
{
stations.add(st.get(i).getStation());
}
ListView list = (ListView) findViewById(R.id.list);
Spinner s1 = (Spinner) findViewById(R.id.spinnerStart);
Spinner s2 = (Spinner) findViewById(R.id.spinnerEnd);
ArrayAdapter<CharSequence> SimpleSpinner1 = new ArrayAdapter<CharSequence>(this, R.layout.spinner, R.id.textView1);
ArrayAdapter<CharSequence> SimpleSpinner2 = new ArrayAdapter<CharSequence>(this, R.layout.spinner, R.id.textView1);
SimpleAdapter nSchedule = new SimpleAdapter(this, departures, R.layout.row,
new String[] {"train", "from", "to"}, new int[] {R.id.TRAIN_CELL, R.id.FROM_CELL, R.id.TO_CELL});
for (CharSequence c : stations)
{
SimpleSpinner1.add(c);
SimpleSpinner2.add(c);
}
list.setAdapter(nSchedule);
s2.setAdapter(SimpleSpinner2);
s1.setAdapter(SimpleSpinner1);
}

Instead of R.id.spinnerStart / R.id.spinnerEnd you need to pass a textView
EDIT:
Spinner spinner1 = (Spinner)findViewById(R.id.spinner1);
ArrayAdapter adapter = new ArrayAdapter(this, R.layout.spinner_item, R.id.textView1);
spinner1.setAdapter(adapter);
textView1 is present in spinner_item layout. Hope this is clear

Try this
// set id for spinner
spinner2 = (Spinner) findViewById(R.id.spinner2);
// prepare a list
List<String> list = new ArrayList<String>();
list.add("list 1");
list.add("list 2");
list.add("list 3");
// set adapter for spinner
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, list);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// set adapter to spinner
spinner2.setAdapter(dataAdapter);
