Generating Edit Text Programmatically in Android

Generating Edit Text Programmatically in Android

You can create it like so:

EditText myEditText = new EditText(context); // Pass it an Activity or Context
myEditText.setLayoutParams(new LayoutParams(..., ...)); // Pass two args; must be LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT, or an integer pixel value.
myLayout.addView(myEditText);

This can be implemented anywhere on the UI thread; a click listener, an onCreate method, and everything in between.

There is a more generic example in this question, and a good rundown of these processes in this blog.

Android TextView and EditText programmatically

LinearLayout rootLayout = (LinearLayout) findViewById(R.id.root_layout);
rootLayout.setOrientation(LinearLayout.VERTICAL);
//this layout still needs to be vertical to hold the children.
for (int i = 0; i < 6; i++) {

   //make a new horizontal LinearLayout each time to hold the children.
    LinearLayout temp = new LinearLayout(this);
    temp.setOrientation(LinearLayout.HORIZONTAL);
    temp.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
        LinearLayout.LayoutParams.WRAP_CONTENT,1));

    TextView textView = new TextView(this);
    textView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
            LinearLayout.LayoutParams.WRAP_CONTENT,1));
    textView.setText("Text");
    temp.addView(textView); //add them to this temporary layout.

    EditText editText = new EditText(this);
    editText.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
            LinearLayout.LayoutParams.WRAP_CONTENT,1));
    temp.addView (editText);

    TextView addTextView = new TextView(this);
    addTextView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
            LinearLayout.LayoutParams.WRAP_CONTENT,1));
    addTextView.setText("Additional Text");
    temp.addView(addTextViewtextView);

    rootLayout.addView(temp);

In this way, you can add several linear layouts inside one. So basically, for each set of TextViews, you are making a separate LinearLayout, and then adding each of these layouts to your main LinearLayout which is still vertical in orientation.

How to add EditText programmatically?

LinearLayout layout=(LinearLayout)view.findViewById(R.id.linearLayout);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
                        android.widget.LinearLayout.LayoutParams.MATCH_PARENT,
                        android.widget.LinearLayout.LayoutParams.WRAP_CONTENT);

                EditText edttext= new EditText(this);
                edttext.setId("edittext");
                edttext.setLayoutParams(params);

            layout.addView(edttext);

Getting the value of Edittext which created programmatically

I guess you want to get the values of the dynamically created EditTexts. You currently replace the instance of the EditText which each creation. Try the below code:

        List<EditText> editTextList = new ArrayList<>();

        private void setChoices() {

        layout = (LinearLayout) findViewById(R.id.linearLayout);
        params = new LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.MATCH_PARENT,
                LinearLayout.LayoutParams.WRAP_CONTENT);
        params.gravity = Gravity.CENTER;
        int marginPixel = 1;
        int marginPixell = 5;
        float densityy =getResources().getDisplayMetrics().density;
        int marginDp = (int)(marginPixel * densityy);
        int margin = (int)(marginPixell * densityy);
        params.setMargins(marginDp, margin, marginDp, margin);

        int num= Integer.parseInt(choicesNumberEDT.getText().toString());

        for (int i = 0; i < num; i++) {

            EditText explanationED= new EditText(this);
            explanationED.setLayoutParams(params);
            editTextList.add(explanationED); //<-------new line here
            layout.addView(explanationED);
            explanationED.setGravity(Gravity.TOP);
            explanationED.setHint("أكتب هنا.....");
            explanationED.setTextSize(14);
            explanationED.setId(i);
            float density = getResources().getDisplayMetrics().density;
            int paddingDp = (int) (Const.paddingPixel * density);
            explanationED.setBackgroundColor(Color.parseColor("#B2E3CC"));
            explanationED.setPadding(paddingDp, paddingDp, paddingDp, paddingDp);

        }

    }

private EditText getText(int position) {
     return editTextList.get(position).getText().toString();
}

OR if you don't want to keep a list of the EditTexts, you can set a tag for each EditText you create using:

    editText.setTag("tag");

and later retrieve it using:

    layout.findViewWithTag("tag");

Android: Dynamically or Programmatically add two EditText in one line and make them relate

Use a horizontal linear layout and add two edit texts inside.

Try this :

LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,       ViewGroup.LayoutParams.WRAP_CONTENT));
linearLayout.setOrientation(LinearLayout.HORIZONTAL);  

Using layout weight as 1 for both edit texts(1.0f is the weight). You can tweak the width and height of the edit texts.

EditText et1 = new EditText(this);
et1.setLayoutParams(new LinearLayout.LayoutParams(0, ViewGroup.LayoutParams.WRAP_CONTENT,1.0f));  

EditText et2 = new EditText(this);
et2.setLayoutParams(new LinearLayout.LayoutParams(0, ViewGroup.LayoutParams.WRAP_CONTENT,1.0f));  

Now add edit texts to the horizontal linearLayout and then add it to your layout.

linearLayout.addView(et1);
linearLayout.addView(et2);
layout.addView(linearLayout);
