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.
Feel free to reply.

Programmatic Toolbar

In my Android assignment we have to create a simple App using only Java and not design view. I want to add icons and text to the toolbar. I can get it to work using design view but I cannot get it to work using Java.
Please advice me if my idea is right. For example to add a button to the toolbar, I create a
android.widget.Button button = new android.widget.Button()
and then add the button to the Toolbar.
My onCreate() function is as follows:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
relative_layout = new RelativeLayout(this);
relative_layout.setBackgroundColor(Color.WHITE);
Toolbar tool_bar = new Toolbar(this);
tool_bar.setTitle("Hello");
tool_bar.setBackgroundColor(Color.RED); // actual one I read from R.color.xyz
tool_bar.setTitleTextColor(Color.WHITE);
tool_bar.setId(1);
// tool_bar.setNavigationIcon(R.drawable.ic_launcher_foreground);
tool_bar.setPopupTheme(R.style.Theme_AppCompat_Dialog);
this.setVisible(true);
this.setSupportActionBar(tool_bar);
RelativeLayout.LayoutParams toolbar_layout = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
toolbar_layout.addRule(RelativeLayout.ALIGN_PARENT_TOP);
toolbar_layout.addRule(RelativeLayout.CENTER_HORIZONTAL);
Button button = new Button(this);
button.setBackgroundColor(Color.GREEN);
button.setText("Button");
button.setId(2);
RelativeLayout.LayoutParams button_layout = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
button_layout.addRule(RelativeLayout.CENTER_HORIZONTAL);
button_layout.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
// button_layout.setMargins(400, 0, 0, 0);
tool_bar.addView(button, button_layout);
relative_layout.addView(tool_bar, toolbar_layout);
this.setContentView(relative_layout);
}
1) I would like to confirm is this is correct way of doing this?
2) I cannot move the button to the right of the screen as shown in the picture, although I used
RelativeLayout.ALIGN_PARENT_RIGHT
How can we set the alignment to the right?

Your Toolbar will look like this after adding this code :
Use this code to crate your toolbar activity.xml Code :
<android.support.v7.widget.Toolbar
android:id="#+id/toolbarAdjustScan"
android:layout_width="match_parent"
android:layout_height="56dp"
android:background="#color/colorPrimary"
android:elevation="6dp"
android:minHeight="56dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/titleToolbar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginLeft="15dp"
android:ellipsize="end"
android:layout_weight="1"
android:maxLines="1"
android:textColor="#color/white"
android:textSize="18dp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="right"
android:padding="10dp"
android:id="#+id/searchAdjustBtn"
android:layout_marginLeft="15dp"
android:ellipsize="end"
android:maxLines="1"
android:text="SEARCH "
android:textColor="#color/white"
android:textSize="13dp" />
</LinearLayout>
</android.support.v7.widget.Toolbar>
Activity.java Code :
Toolbar toolbarTop;
Call setToolbar() inside from your onCreate()
private void setToolbar() {
toolbarTop = (Toolbar) findViewById(R.id.toolbarAdjustScan);
setSupportActionBar(toolbarTop);
TextView search = (TextView)toolbarTop.findViewById(R.id.searchAdjustBtn);
TextView titleToolbar = (TextView)toolbarTop.findViewById(R.id.titleToolbar);
titleToolbar.setText("TakeInventory");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setElevation(0);
search.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), TakeInventoryResult.class);
// Bundle args = new Bundle();
// args.putSerializable("ARRAYLIST",(Serializable)inList);
// intent.putExtra("BUNDLE",args);
startActivity(intent);
finish();
}
});
}

The toolbar is just a ViewGroup. So just as you add views to any ViewGroup programmatically, do the same treatment for the toolbar.
Button bt = new Button(this);
bt.setText("Button");
LinearLayout.LayoutParams params = new
LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.FILL_PARENT);
params.gravity = Gravity.RIGHT;
button.setLayoutParams(params);
toolbar.addView(bt);
Happy to help :)

row generator with textviews

This is my code for a n app in which i want to add textviews in a row
dynamically on click of a button and not working can you tell me whats wrong with the code,i am just a beginner.
thanking you in anticipation.
public class MainActivity extends AppCompatActivity {
Button save;
TableLayout tableLayout;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button save = (Button) findViewById(R.id.save);
TableLayout tableLayout = (TableLayout) findViewById(R.id.table1);
save.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
TableRow tableRow;
TextView textView;
TableLayout tableLayout = (TableLayout) findViewById(R.id.table1);
for (int i = 0; i < 4; i++) {
tableRow = new TableRow(getApplicationContext());
for (int j = 0; j < 3; j++) {
textView = new TextView(getApplicationContext());
textView.setText("####");
textView.setPadding(20, 20, 20, 20);
tableRow.addView(textView);
}
tableLayout.addView(tableRow);
}}});
setContentView(tableLayout);
}
}
and my xml layout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.kalla.monu.saplist.MainActivity">
<TableLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_alignParentEnd="true"
android:layout_marginEnd="28dp"
android:layout_marginTop="160dp"
android:id="#+id/table1"
android:background="#color/colorPrimaryDark">
<TableRow
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/darker_gray"/>
<TableRow
android:layout_width="match_parent"
android:layout_height="match_parent"
android:backgroundTint="#android:color/holo_green_dark" />
<TableRow
android:layout_width="match_parent"
android:layout_height="match_parent" />
<TableRow
android:layout_width="match_parent"
android:layout_height="match_parent" />
</TableLayout>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="save"
android:id="#+id/save" />
</RelativeLayout>

Try this,
I assume you are trying to add tablerows and textviews both dynamically. So I have removed existing tablerows from layout xml.
TableLayout tableLayout = (TableLayout) findViewById(R.id.table1);
save.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
TableRow tableRow;
TextView textView;
for (int i = 0; i < 4; i++) {
tableRow = new TableRow(this);
for (int j = 0; j < 3; j++) {
textView = new TextView(this);
textView.setText("####");
textView.setPadding(20, 20, 20, 20);
tableRow.addView(textView);
}
table1.addView(tableRow);
}}});
In XML:
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/table1"/>

I want to add n-rows in table "myTable" at run time what should i do ?
currently i am using this code
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TableLayout myTable = (TableLayout) findViewById(R.id.myTable);
TextView tv = new TextView(this);
for (int x = 0; x < 5; x++) {
tv.setText("This is row number=" + (x + 1));
TableRow tr = new TableRow(this);
tr.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
tr.addView(tv);
myTable.addView(tr, LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
}
}
but it is giving me this error
03-26 00:29:34.070:
E/AndroidRuntime(2230): java.lang.RuntimeException: Unable to start activity ComponentInfo{assignment.1/assignment.1.myView}: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TableLayout myTable = (TableLayout) findViewById(R.id.myTable);
for (int x = 0; x < 5; x++) {
TextView tv = new TextView(this);
tv.setText("This is row number=" + (x + 1));
TableRow tr = new TableRow(this);
tr.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
tr.addView(tv);
myTable.addView(tr, LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
}
}
Try now a small and minor change

I guess this is because you are creating the row object new every time in your loop, but you dont do this with the TextView Object.
Like this it should work:
TableLayout myTable = (TableLayout) findViewById(R.id.myTable);
TextView tv;
TableRow tr;
for (int x = 0; x < 5; x++) {
tv = new TextView(this);
tv.setText("This is row number=" + (x + 1));
tr = new TableRow(this);
tr.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
tr.addView(tv);
myTable.addView(tr, LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
}
