How to display the EditText fields text in the TextView

Question

Of late I was just trying to create a mems geneator app, yes I had been following the new bostons and in that buckey created them using 2 fragments and here i just want to do in a single main activity, but I just can't figure out how to retrieve the text from the edit text field and set the text of Text view to it. I know it's pretty a newbie question but still I don't know how to code it so please help...

I had just imported some widgets,views,etc and done some modified the on create function and my on create function is:

public class MainActivity extends AppCompatActivity {

public static EditText topText;
public static EditText bottomtext;
public static TextView top;
public static TextView bottom;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    topText = (EditText) findViewById(R.id.topedit);
    bottomtext = (EditText) findViewById(R.id.bottomedit);
    top = (TextView) findViewById(R.id.top);
    bottom = (TextView) findViewById(R.id.bottom);
    Button myButton = (Button) findViewById(R.id.button);
    myButton.setOnClickListener(
            new Button.OnClickListener() {
                public void onClick(View V) {
                    top.setText((CharSequence) topText);
                    bottom.setText((CharSequence) bottomtext);
                }
            }
    );
}

Simply do this:

if(topText.getText()!=null){
top.setText(topText.getText().toString());
}
if(bottomtext.getText()!=null){
bottom.setText(bottomtext.getText().toString());
}

Also read full documentation of android before coming to the implementations, you will find almost everything in the documentation. You can refer to http://developer.android.com – Aakash Sep 17 '15 at 17:56
Thanks man it worked with just some small modification i.e inverting null and the topText.getText() and the same for bottom also like- if(null != topText.getText()){ top.setText(topText.getText().toString()); } if (null != bottomtext.getText()) { bottom.setText(bottomtext.getText().toString()); } – Prudhvi Reddy Sep 17 '15 at 18:01

Try this to get text of the EditText field:

CharSequence text = topText.getText();

And set the text above for the textView:

top.setText(text);

Use this short example to understand the concept

store=ret.getText().toString();

show.setText(store);

Explanation

ret: is the name of the edit text field;

store: is used to hold anything gotten from ret (text field)

show.setText(store) displays the result in the textview
