Question

How can I make it so that it uses whatever is in the edittext, as the text view like if I type “hello” push the button and it sets the textview as “hello” then when you push the button again it erases it?

  package com.purelymean.earnings;
  import org.w3c.dom.Text;

  import android.app.Activity;
  import android.os.Bundle;
  import android.util.Log;
  import android.view.View;
  import android.view.View.OnClickListener;
  import android.widget.Button;
  import android.widget.TextView;

    public class Main extends Activity{
/**Called when activity is first created. */
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);
    Button b = (Button) findViewById(R.id.button);
    Text et = (Text) findViewById(R.id.editText1);
    TextView tx = (TextView) findViewById(R.id.textView1);


    b.setOnClickListener(new OnClickListener() {


        @Override
        public void onClick(View v) {





        }
    });

}
}

Another way to do it (adding on to La bla bla): For displaying the editText in TextView first create a method that happens when the button is clicked:

public void displayEditText(View view) { }

In your xml for your button add this:

android:onClick="displayEditText"

To get the EditText value put this inside the displayEditText

String editTextValue = et.getText().toString;
To display this do the following:

tx.setText(editTextValue);

Final solution:

public void displayEditText(View view) {        
    if (tx.getText().toString().equals("")) {
         String editTextValue =   et.getText().toString;
           tx.setText(editTextValue);
    } else {
         tx.setText("");
         tv.setText("");
    }
}
