It’s very simple to add textviews and buttons to linear layout programmatically, just follow this steps. The fist step. Add a LinearLayout in .xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/activity_linear_layout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/thewordis"
    android:orientation="horizontal"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin">

</LinearLayout>

Now in .class add:
1) add LinearLayout
2) add LayoutParams
3) add TextView
4) add Button
5) add the TextView and the Button to View

import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;

public class ClassTheDeveloperWorldIsYours extends Activity{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.the_developer_world_is_yours);

        //added LInearLayout
        LinearLayout linearLayout = (LinearLayout) findViewById(R.id.activity_linear_layout);

        //added LayoutParams
        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        linearLayout.setOrientation(LinearLayout.VERTICAL);

        //add textView
        TextView textView = new TextView(this);
        textView.setText("The developer world is yours");
        textView.setId(1);
        textView.setLayoutParams(params);

        // added Button
        Button button = new Button(this);
        button.setText("thedeveloperworldisyours");
        button.setId(2);

        //added the textView and the Button to LinearLayout
        linearLayout.addView(textView);
        linearLayout.addView(button);

    }
}
