AndroidStudio: Display input field on click

I am building an android app where a user can create, view, delete, and update his cooking recipes.
If a user is creating a recipe I want him to be able to add steps like: step1:, step2:, etc.
So if a user needs another step he simply tabs on a button "add step" and an input field should appear below the previous step.
I tried searching for this but didn't find anything. Could someone help me into the right direction?

With the following piece of code I am able to create new EditText fields on button click.
private int hint = 0;
public void addStep(View view) {
//Get the linearLayout where the EditText fields will appear.
LinearLayout container = findViewById(R.id.linearLayout);
//Increment id by 1.
hint++;
//Create a new EditText field.
EditText step = new EditText(this); //Creating new TextView
//Add attributes to EditText
step.setId(hint);
step.setText("step");
step.setMaxLines(1);
step.setWidth(160);
//Finally Display the EditText field in the LinearLayout
container.addView(step);
}

Suppose you are using constraintlayout
EditText step1 = findViewById(R.id.step1);
EditText step2 = new EditText(this);
step2.setId(R.id.step2);
step2.setLayoutParams(new ConstraintLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));
ConstraintSet constraintSet = new ConstraintSet();
ConstraintLayout constraintLayout = findViewById(R.id.parent);
constraintLayout.addView(step2);
constraintSet.clone(constraintLayout);
constraintSet.connect(step2.getId(),ConstraintSet.START,ConstraintSet.PARENT_ID,ConstraintSet.START,0);
constraintSet.connect(step2.getId(),ConstraintSet.END,ConstraintSet.PARENT_ID,ConstraintSet.END,0);
constraintSet.connect(step2.getId(),ConstraintSet.TOP,step1.getId(),ConstraintSet.BOTTOM,0);
constraintSet.constrainWidth(R.id.step2,ConstraintSet.MATCH_CONSTRAINT);
constraintSet.constrainHeight(R.id.step2,ConstraintSet.MATCH_CONSTRAINT);
constraintSet.applyTo((ConstraintLayout)findViewById(R.id.parent));

android working with Views

In my activity I have the following views
TextView player1;
TextView player2;
TextView player3;
TextView player4;
EditText player1name;
EditText player2name;
EditText player3name;
EditText player4name;
Each of the TextView's has the onclick listener applied to it. and so fires the OnClick function.
When we get to the onClick this is what i am currently doing:
#Override
public void onClick(View v) {
//the v variable is the clicked textview, in this case "player1"
//hide the textview and show the resultant edittext
v.setVisibility(View.GONE);
player1name.setVisibility(View.VISIBLE);
//set focus on edit text and when focus is lost hide it and set the textview text
player1name.requestFocus();
imm.showSoftInput(player1name, InputMethodManager.SHOW_FORCED);
player1name.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View y, boolean x) {
v.setVisibility(View.VISIBLE);
player1name.setVisibility(View.GONE);
imm.hideSoftInputFromWindow(player1name.getWindowToken(), 0);
String name = player1name.getText().toString();
if (name.equals("")) {
v.setText("Player Name1");
} else {
v.setText(name);
}
}
});
}
However with this solution I will need to duplicate this code and change the view names for player2 - player2name, player3 - player3name etc
i can obviously grab the clicked TextView via v, however what i cant seem to do is grab its corresponding EditText.
i had thought of doing this:
View test = v + "name";
//then i replace all references to player1name with the test variable
but it doesnt work it wants me to convert View test; into a string
any suggestions?
EDIT: made it easier to understand my question

View test = v + "name";
will give a compile error. Because "v" is not a string type. and also even if it was String, test is not. This line is pretty wrong.
There a few options to achieve what you want,
You can use hashmap
Declare a global field for hashmap
private final HashMap<Integer,EditText> map = new HashMap<Integer,EditText>();
and in onCreate method put your textview id as key, and put your edittext variables in value.
player1name = (EditText) findViewById(R.id.player1name);
map.put(R.id.textView1, player1name);
// for the rest
in onClick method
EditText e = map.get(v.getId());
Then replace them with "e"
e.requestFocus(); //example

Will you please state your problem clearly? Currently, your language is very ambiguous and I can not figure out, exactly what are you looking for. It will help us to know your problem and in turn solve it.

Change Text in EditText when pressing the EditText

Some EditText (Like when you write a text message) can be clicked and opened, so you can change the text inside the EditText. It also gives you the keyboard so you can write, etc.
How do I achieve the same thing?
Currently I got this:
public void onDescriptionBoxClick(View view) {
EditText et = (EditText) this.findViewById(R.id.editText1);
}
And I don't know what to do other than that.
Do I have to call the keyboard forth so the user can edit the text in the box?

I would place an EditText element right next to your textView which has the attribute android:visibilty="gone"
then in your code:
public void onDescriptionBoxClick(View view) {
TextView tv = (TextView) this.findViewById(R.id.textView2);
tv.setVisibility(View.GONE);
EditText et = (EditText) this.findViewById(R.id.editText2);
et.setVisibilty(View.VISIBLE);
}

You can't edit text using a TextView. to accomplish what you want you have to replace the TextView with a EditText widget. and then replace it with the TextView containing the text entered in the EditText.
You can accomplish this in a few ways:
Using Fragment, more compicated.
You can use simple TextView and EditText widgets and set their Visability accordingly.

dynamic create editbox in android?

I want to create a Editbox dynamically when i click a add button and i also want to get the values typed in that Editbox when i click in save button.
Please Help me. Regards. Augustine

Try out this:
LinearLayout mLinearLayout = new LinearLayout(this);
mLinearLayout = (LinearLayout)findViewById(R.id.mylinearlayout);
Button lButton = (Button)findViewById(R.id.mybtnid);
lButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
EditText lEditText = new EditText(this);
lEditText.SetText("Text Here");
mLinearLayout.addView(lEditText);
}
}

To get the values typed into the EditText, you need to additionally set an identifier for the view.
lEditText.setId(2); //you can use any integer ID
Then, you can retrieve the text inside the OnClickListener of the save button as:
EditText lEditText = (EditText)findViewById(2);
String txt = lEditText.getText().toString();

To create an edit text dynamically or programmatically:
EditText ed = new EditText(context);
Set whatever parameters you want to set for this edit text and then add this in your view:
view.addView(ed);
OR
view.addView(ed, layoutParams);

you can create EditText with the following code inside your Activity
EditText _edit = new EditText(this);
Then to add this to you activity layout you have to get the particular layout by it id
For Ex.
LinearLayout linear = (LinearLayout)findViewById(R.id.linear);
then simple add this EditText object to the LinearLauout by using the following code..
linear.addView(_edit);

How to get EditText value and display it on screen through TextView?

I want to get the user input for the EditText view and display it on the screen through TextView when the Button is clicked. I also, want to know what modifications can be done on the string.xml file to do this.

I didn't get the second question, maybe you can elaborate...but for your first query.
String content = edtEditText.getText().toString(); //gets you the contents of edit text
tvTextView.setText(content); //displays it in a textview..

I'm just beginner to help you for getting edittext value to textview. Try out this code -
EditText edit = (EditText)findViewById(R.id.editext1);
TextView tview = (TextView)findViewById(R.id.textview1);
String result = edit.getText().toString();
tview.setText(result);
This will get the text which is in EditText Hope this helps you.

EditText ein=(EditText)findViewById(R.id.edittext1);
TextView t=new TextView(this);
t.setText("Your Text is="+ein.getText());
setContentView(t);

bb.setOnClickListener(
new View.OnClickListener()
{
public void onClick(View view)
{
String s1=tt.getText().toString();
tv.setText(s1);
}
}
);

First get the text from edit text view
edittext.getText().toString()
and Store the obtained text in a string, say value.
value = edittext.getText().toString()
Then set value as the text for textview.
textview.setText(value)

yesButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
eiteText=(EditText)findViewById(R.id.nameET);
String result=eiteText.getText().toString();
Log.d("TAG",result);
}
});

Easiest way to get text from the user:
EditText Variable1 = findViewById(R.id.enter_name);
String Variable2 = Variable1.getText().toString();

in "String.xml" you can notice any String or value you want to use, here are two examples:
<string name="app_name">My Calculator App
</string>
<color name="color_menu_home">#ffcccccc</color>
Used for the layout.xml: android:text="#string/app_name"
The advantage: you can use them as often you want, you only need to link them in your Layout-xml, and you can change the String-Content easily in the strings.xml, without searching in your source-code for the right position.
Important for changing language, you only need to replace the strings.xml - file

Use the following code when clicked on the button :
String value = edittext.getText().toString().trim(); //get text from editText
textView.setText(value); //setText in a textview
Hope to be useful to you.

Try this->
EditText text = (EditText) findViewById(R.id.text_input);
Editable name = text.getText();
Editable is the return data type of getText() method it will handle both
string and integer values

First get the value from edit text in a String variable
String value = edttxt.getText().toString();
Then set that value to textView
txtview.setText(value);
Where edttxt refers to edit text field in XML file
and txtview refers to textfield in XML file to show the value
