Creating new Textviews in another activity based onClick android

Question

I would like to create a new textview to hold the information sent each time the button is clicked. I have the data I want passing to another screen in a textview but each time i try to put new data it overrides this data because it uses the same textView (textview4). I would like to know if there is a way of creating a new text view to hold my data each time the button is clicked. I hope I was clear enough, thanks.

This code is from a class called CreateWorkout.Java

    public void createNewWorkout (View view){
    TextView Exercise1TextView = (TextView) findViewById(R.id.Exercise1TextView);
    EditText  weightEntered = (EditText)findViewById(R.id.WeightLiftedEditText);
    EditText  reps = (EditText)findViewById(R.id.RepsEditText1);
    EditText  sets = (EditText)findViewById(R.id.setsEditText1);

    Intent getWorkoutIntent = new Intent(this, SelectWorkout.class);

    getWorkoutIntent.putExtra("Workout", Exercise1TextView.getText().toString()
            + " " + weightEntered.getText().toString() + "kg"
            + " " + reps.getText().toString() + " reps"
            + " " + sets.getText().toString() + " sets");

    startActivity(getWorkoutIntent);
}

This is where the intent is called. This is from SelectWorkout.Java

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.select_workout);

    TextView textView4 = (TextView) findViewById(R.id.textView4);
    textView4.setText(getIntent().getExtras().getString("Workout"));
}

i want to take the data entered here to the next screen. So the exercise name(Leg Press), weight(50), set(3), reps(10)

creating a new text view to hold my data each time

Not an exact answer, but this should guide you in the right direction. You could do something like the following:

• Get your bundle
• Iterate bundle
• Create Textviews during iteration and add them to "your_main_layout" which is the id of the main layout inside select_workout

The bundle is the extra data you're sending over from the Intent. The Iterate is going through each item you sent over to this new intent, the create part refers to creating a TextView for each item you sent over. I've supplied links to what I found below.

• Listing all extras of an Intent

  //Get a bundle:
  for (String key : bundle.keySet()) {
  // This is each value (text) you sent over from the last intent 
      Object value = bundle.get(key);
  //output data to log, so you can see what prints out
      Log.d(TAG, String.format("%s %s (%s)", key, value.toString(), value.getClass().getName()));
  
  //adding a textview to a layout called your_main_layout (which can be a linear layout or something) 
  //with value.toString() as the text
  your_main_layout.addView(createATextView(LayoutParams.WRAP_CONTENT,
              LayoutParams.WRAP_CONTENT, RelativeLayout.ALIGN_PARENT_RIGHT,
              value.toString(), 20, 10, 20));
  }
  

• How can I add a TextView to a LinearLayout dynamically in Android?

  //method to create view:
  public TextView createATextView(int layout_widh, int layout_height, int align,
  String text, int fontSize, int margin, int padding) {
  
  TextView textView_item_name = new TextView(this);
  
  // LayoutParams layoutParams = new LayoutParams(
  // LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
  // layoutParams.gravity = Gravity.LEFT;
  RelativeLayout.LayoutParams _params = new RelativeLayout.LayoutParams(
          layout_widh, layout_height);
  
  _params.setMargins(margin, margin, margin, margin);
  _params.addRule(align);
  textView_item_name.setLayoutParams(_params);
  
  textView_item_name.setText(text);
  textView_item_name.setTextSize(TypedValue.COMPLEX_UNIT_SP, fontSize);
  textView_item_name.setTextColor(Color.parseColor("#000000"));
  // textView1.setBackgroundColor(0xff66ff66); // hex color 0xAARRGGBB
  textView_item_name.setPadding(padding, padding, padding, padding);
  
  return textView_item_name;
  
  }
