How to get EditText value and display it on screen through 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);

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..
