Hi you can listen on changes on the Edit text:
How do listen EditText?
When you get text written in the edit text you can make the toggleRadiobutton dissapear with toggleRadiobutton.setVisibilty(View.INVISIBLE) or you disable it with toggleRadiobutton.setEnabled(false).
The same if you detect that there is no text in the edittext, you can re-enable the togglebutton.
With the toggleRadioButton you would take the same approach. You check the status of button in on OnClickListener and enable or disable the Edittext accordingly:
toggleRadioButton.setOnClickListener(new OnClickListener(View v){
if(((RadioButton)v).isChecked()){
edittext.setEnabled(false);
}else{
edittext.setEnabled(true);
}
});

How to store a value from a vector and then display it on an editText in android?

I have a situation where there are 3 editText fields created dynamically and those values should be stored in vector and should be displayed again after i click on button "ADD" after three fields are added?
Any help will be appreciated, thanks in advance.

You should set OnClickListener
final EditText editText1 = new EditText(context);
final EditText editText2 = new EditText(context);
final EditText editText3 = new EditText(context);
final Vector<String> vector = new Vector<String>();
// Adding editTextes to layout code here....
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
vector.add(editText1.getText());
vector.add(editText2.getText());
vector.add(editText3.getText());
}
});

how to display values from dynamically created EditText

final LinearLayout ll=new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
scrl.addView(ll);
Button add_btn=new Button(this);
add_btn.setText("Click to add TextViiews and EditTexts");
ll.addView(add_btn);
add_btn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//String str;
TextView tv=(TextView)findViewById(R.id.tv1);
EditText et2=new EditText(getApplicationContext());
String s=et2.getText().toString();
tv.setText(s);
ll.addView(et2);
I have created a button when i click on this button i will get edittext dynamically if i enter a value i should display the value I don't know how to display value and make use of it if suppose i want to add entered values in dynamically created edit text.

You cannot get text if you haven't added the view.Also you add textview on click of button. You can remove textview creation from onClick() and add it outside of it
EDIT(something like this):
final LinearLayout ll=new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
scrl.addView(ll);
Button add_btn=new Button(this);
add_btn.setText("Click to add TextViiews and EditTexts");
ll.addView(add_btn);
add_btn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
String s=et2.getText().toString();
tv.setText(s);
}
});
TextView tv=(TextView)findViewById(R.id.tv1);
EditText et2=new EditText(getApplicationContext());
ll.addView(et2);

How to display data in TextView

I have a view in which there is a text box where user enters data, when clicks on submit, I want to store the input and display in another box.
final EditText edittext = (EditText) findViewById(R.id.edittext);
mText = (TextView) findViewById(R.id.timepicker_input);
How can I do it, please help

final EditText edittext = (EditText) findViewById(R.id.edittext);
TextView mText = (TextView) findViewById(R.id.timepicker_input);
mText.setText(edittext.getText().toString());

String info = edittext.getText().toString();
mText.setText(info);

final EditText edittext = (EditText) findViewById(R.id.edittext);
TextView mText = (TextView) findViewById(R.id.timepicker_input);
String storedData = edittext.getText().toString();
mText.setText(storedData);
Here, you can use the string storedData in another activity or to setText for another editText (textbox)
