Programmatically add textView with constraint

Programmatically add textView with constraint - java

I have a ScrollView defined by the xml. Inside of it I want to have two textView like in this photo :
Doing that in xml is fine. But how to add them programmatically? Here's what the code look like without the two TextView example:
.xml file :
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:id="#+id/rl"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/transparent"
tools:context=".InventoryActivity">
<ImageView
android:id="#+id/imageView9"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"

app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="1.0"
app:srcCompat="#drawable/inventorylayoutbg" />
<ImageView

android:layout_width="61dp"
android:layout_height="59dp"
android:layout_marginBottom="8dp"
android:layout_marginEnd="8dp"

android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:onClick="closeDialog"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.254"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"

android:layout_height="wrap_content"
android:orientation="vertical"></LinearLayout>
</ScrollView>
</android.support.constraint.ConstraintLayout>
.java file
package com.example.jsciampi.tapper;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.view.View;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.ScrollView;
public class InventoryActivity extends AppCompatActivity {
//Form
ScrollView sv;
LinearLayout ll;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_inventory);
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int width = (int)(dm.widthPixels*.9);
int height = (int)(dm.heightPixels*.8);
getWindow().setLayout(width,height);
sv = findViewById(R.id.sv);
ll = findViewById(R.id.ll);
for(int i = 0; i < 5; i++){
Button b = new Button(InventoryActivity.this);
//Add Constraint there
ll.addView(b);
}
}
public void closeDialog(View view) {
finish();
}
}
The second TextView had this xml config:
<TextView
android:id="#+id/textView2"
android:layout_width="324dp"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginEnd="8dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:text="TextView"
app:layout_constraintBottom_toBottomOf="#+id/sv"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/firstText"
app:layout_constraintVertical_bias="0.0" />
and I really just need to converto from xml to java this part here :
app:layout_constraintBottom_toBottomOf="#+id/sv"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/aads"
app:layout_constraintVertical_bias="0.0"
Can anyone help me out?

for (int i = 0; i < 5; i++) {
View row = LayoutInflater.from(this).inflate(R.layout.image_text_row,null,false);
ll.addView(row);
}
add the below layout to file with name image_text_row.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/background_dark"
android:orientation="horizontal">
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="1"
android:src="#android:drawable/ic_dialog_email" />
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"

Why doesn't the replace function for fragments work?

I'm trying to open a Fragment from a Activity by using the fragmentManager.replace() function, but it doesn't do anything and the Logcat tells me nothing either. I have tried using both FragmentContainerView and FrameLayout inside my activity_main.xml, and even using the activity's ConstraintLayout ID to host the Fragment, but to no avail.
Here are the codes for my Activity that should open the fragment, and the fragment code itself:
OsActivity.java
import androidx.fragment.app.FragmentTransaction;
import android.os.Bundle;
import android.view.View;
import com.leonardomaito.autocommobile.fragments.NewOsFragment;
import autocommobile.R;
public class OsActivity extends AppCompatActivity {
NewOsFragment newOsFragment = new NewOsFragment();
private View v;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_os);
}
public void createNewOs(View view) {
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.setReorderingAllowed(true);
fragmentTransaction.replace(R.id.osFragmentContainer, newOsFragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
}
NewOsFragment.java
import android.os.Bundle;
import androidx.fragment.app.Fragment;
import androidx.fragment.app.FragmentTransaction;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import autocommobile.R;
public class NewOsFragment extends Fragment {
private Button btOsNext;
private Button btOsCancel;
private Fragment nextOs = new Fragment();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_new_os, container, false);
btOsNext = view.findViewById(R.id.btNextOs);
btOsCancel = view.findViewById(R.id.btCancelNewOs);
return view;
}
public void nextOsStep(View view) {
FragmentTransaction fragmentManager = getActivity()
.getSupportFragmentManager()
.beginTransaction()
.replace(R.id.fragment_new_os, nextOs);
}
}

Shouldn't the replace function be opening my fragment on top of my activity? Is there something I'm doing wrong? The majority of other posts adressing this situation seemed to use .add instead of .replace, and were fixed by doing so.

Android LayoutInflator - Multiple views in for loop

I am creating my first app with Java for android in android studio and have some problems with the LayoutInflator.
The java code of the Activity looks like this:
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ImageButton;
import android.widget.LinearLayout;
import android.widget.TextView;
import java.io.Serializable;
import java.util.ArrayList;
public class MatchActivity extends MatchSettingsActivity implements View.OnClickListener, Serializable {
public ArrayList<Player> matchParticipants = new ArrayList<>();
public String matchType;
public int setsAmount;
public int legsAmount;
public String checkOutType;
public String atcMode;
public int matchFinished;
public final String matchType501 = "501";
public final String matchType301 = "301";
public ArrayList<View> playerRowViewsArrayList = new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_match);
ImageButton backButton = findViewById(R.id.match_back_button);
backButton.setOnClickListener(this);
Match match = (Match) getIntent().getSerializableExtra("match_object");
setMatchSettings(match.matchParticipants, match.matchType,
Integer.parseInt(match.setsAmount), Integer.parseInt(match.legsAmount),
match.checkOut, match.atcMode, match.matchFinished);
createMatchUI(matchType, matchParticipants);
}
#Override
public void onClick(View v) {
super.onClick(v);
if (v.getId() == R.id.match_back_button) {
Intent matchIntent = new Intent(MatchActivity.this, MainActivity.class);
MatchActivity.this.startActivity(matchIntent);
setContentView(R.layout.activity_main);
}
}
public void createMatchUI(String matchType, ArrayList<Player> matchParticipants) {
LinearLayout mainMatchLayout = findViewById(R.id.main_match_layout);
LayoutInflater inflater = getLayoutInflater();
if (matchType.equals(matchType501) || matchType.equals(matchType301)) {
for (int i=0; i<matchParticipants.size(); i+=1) {
View playerRowView = inflater.inflate(R.layout.player_row_layout, mainMatchLayout, false);
TextView nameTextView = playerRowView.findViewById(R.id.name);
TextView pointsTextView = playerRowView.findViewById(R.id.points);
TextView averageTextView = playerRowView.findViewById(R.id.average);
TextView lastDart1 = playerRowView.findViewById(R.id.last_d1);
TextView lastDart2 = playerRowView.findViewById(R.id.last_d2);
TextView lastDart3 = playerRowView.findViewById(R.id.last_d3);
TextView lastDartsCombined = playerRowView.findViewById(R.id.last_darts_combined);
nameTextView.setText(matchParticipants.get(i).playerName);
if (matchType.equals(matchType501)) {
pointsTextView.setText(matchType501);
} else {
pointsTextView.setText(matchType301);
}
averageTextView.setText("");
lastDart1.setText("");
lastDart2.setText("");
lastDart3.setText("");
lastDartsCombined.setText("");
playerRowViewsArrayList.add(playerRowView);
}
for (int i1=0; i1<playerRowViewsArrayList.size(); i1+=1) {
mainMatchLayout.addView(playerRowViewsArrayList.get(i1));
}
}
}
public void setMatchSettings(ArrayList<Player> matchParticipants, String matchType,
int setsAmount, int legsAmount, String checkOutType,
String atcMode, int matchFinished) {
this.matchParticipants = matchParticipants;
this.matchType = matchType;
this.setsAmount = setsAmount;
this.legsAmount = legsAmount;
this.checkOutType = checkOutType;
this.atcMode = atcMode;
this.matchFinished = matchFinished;
}
}
In the method createMatchUI I am trying to display one view for each player Object in a list.
The layout that should be created for each player using the LayoutInflator looks like this

The problem I am facing is, that always only one view is added to the root layout (mainMatchLayout) like this:
Instead I want one layout for each player object that exists in my ArrayList matchParticipants.
Can anyone figure out what I'm doing wrong?
Thank you.

Thanks for help I will try to repair it but don't know how.
This is very important to repair this for me. :)

Looks all good except textview1 color.
Add below line for the textview1 in layout xml
<TextView
android:id="#+id/textView1"
android:textColor="#android:color/black"

Second Class
package com.example.we.reportcardjavaclass;
import android.os.Bundle;
import android.widget.TextView;
/**
* Created by we on 08-07-2017.
*/
public class result extends MainActivity{
public TextView one, two, three, four, five, six;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.result);
setTitle(bang1+"s Result");
one = (TextView) findViewById(R.id.one);
one.setText(bang1);
two = (TextView) findViewById(R.id.two);
two.setText(bang2);
three = (TextView) findViewById(R.id.three);

}
}
EditText values are getting stored MainActivity.java in variables bang - 123456. I added public modifier while declaring them so I can access these in second class too. In second class I want to use these variable values to set in into Textviews but while running it is not showing the value.
I have also attached the screenshots of both layouts after running in my emulator.
Screenshot 1
Screenshot 2
In second layout it is supposed to show name and other values.

I would suggest that you take a few steps back and get a better understanding of Android's fundamentals, including Activities in general. Perhaps a good place to start, would be understanding the Activity Lifecycle.
An answer to your question isn't very simple, because the way in which Android works is likely very different from your understanding.
In short, your second activity is a completely different instance of a class than the first. Extending the second from the first does not mean that the assigned variables are available to the second, it merely means that the class inherits the structure of its parent in the form of methods and fields.
You should instead be designing your activities in such a way that they relay those strings. When launching your second activity, include those strings in the intent when starting it.
For instance:
public class MainActivity extends AppCompatActivity {
// ...
/** Your method where the second activity is launched */
public void onButtonClicked() {
Intent intent = new Intent(this, SecondActivity.class);
intent.putString(SecondActivity.EXTRA_BANG1, bang1);
// ...
startActivity(intent);
}
}
public class SecondActivity extends AppCompatActivity {
public static final String EXTRA_BANG1 = "bang1";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.result);
// ...
TextView tvOne = (TextView) findViewById(R.id.one);
// ...
String bang1 = getIntent().getString(EXTRA_BANG1);
tvOne.setText(bang1);
}
}
I thoroughly recommend reading up in the Android documentation (it's excellently written!) to better understand how (and why) it works through this mechanism. In particular, this article on Sending data between activities is very relevant to you.

If you want to use these values in another activity then simply pass these values along with the intent that is used to start a new activity.
MainActivity.java
Intent i = new Intent(MainActivity.this,SecondActivity.class);
i.putExtra("Bang1",bang1);
i.putExtra("Bang2",bang2);
i.putExtra("Bang3",bang3);
...
And you can get them in the SecondActivity.java file as:
Intent i =getIntent();
int bang1 = i.getIntExtra("Bang1");
...
But instead so choosing the string names as shown i would suggest to create a new class to store the the string names as final string constants in order to avoid any kind of mistake.
Or you can directly declare these variables as static and access them in the SecondActivity by referring to their names as :
int bang1 = MainActivity.bang1;
