Question

In android app development wanted to create a EditText from java code without using XML,
So i wrote this

 import android.os.Bundle;
    import android.app.Activity;
    import android.view.Menu;
    import android.widget.EditText;
    public class MainActivity extends Activity {
        private static final String initMess="Hello Arun";
        private static final int VISIBLE = 0;
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            EditText editText = new EditText(this);
            editText.setText(initMess.toString());
            editText.setVisibility(VISIBLE);
        }

        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            getMenuInflater().inflate(R.menu.activity_main, menu);
            return true;
        }
    }

But while running the app in emulator EditText was not visible.

How to create an EditText using java only ?

Answer 1

ScrollView sv = new ScrollView(this);

LinearLayout ll = new LinearLayout(this);

ll.setOrientation(LinearLayout.VERTICAL);
sv.addView(ll);

EditText et = new EditText(this);

et.setText("weeeeeeeeeee~!");

ll.addView(et);


this.setContentView(sv);
