Because the condition in if block returns false Use this code instead.

final Button butt = (Button) findViewById(R.id.butt);

butt.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
       final EditText frag = (EditText) findViewById(R.id.frag); 
       final TextView hello = (TextView) findViewById(R.id.hello); 
       String verb = frag.getText().toString();
       if ("abc".equals(verb)) {
           hello.setText("Hello");
       }
    }
}

When comparing string, always use .equals method

Example:

String str1 = "yourstring1";
String str2 = "yourstring2";

if(str1.equals(str2))//return false
{...}
