MainActivity.java

package com.example.testaddview;

import java.util.ArrayList;
import java.util.List;

import org.w3c.dom.Element;
import org.w3c.dom.NodeList;


import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.TextView;

public class MainActivity extends Activity {

    LinearLayout LIN_Main;

    TextView TV_GroupTitle;

    LayoutInflater LYOTInf;

    View VIW_AllItems;


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


        LIN_Main = (LinearLayout) findViewById(R.id.LIN_Main);

        LYOTInf = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        VIW_AllItems = LYOTInf.inflate(R.layout.items,null);

        TV_GroupTitle = (TextView) VIW_AllItems.findViewById(R.id.TV_Added); 

        LIN_Main.addView(TV_GroupTitle);



    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

Because you are missing `android:id` for the `TextView` inside activity_main.xml? — Shashank Kadne, Nov 22 '16 at 17:14
You can copy the complete TextView block as is. You are trying to retrieve it by id inside the activity and as it does not have an id, it must be failing. — Shashank Kadne, Nov 22 '16 at 17:25
you are right . but i need to do this . because i want to create a form programmatically . — Farhad Aghajanian, Nov 22 '16 at 17:34
then this code is for what ? VIW_AllItems = LYOTInf.inflate(R.layout.items,null); — Farhad Aghajanian, Nov 22 '16 at 17:37
Do you want to dynamically add Views which will be similar to your first layout? Please refer this thread if that's the ask, http://stackoverflow.com/questions/6216547/android-dynamically-add-views-into-view — Shashank Kadne, Nov 22 '16 at 17:39
this code `Toast.makeText(getBaseContext(), TV_GroupTitle.getText().toString(), Toast.LENGTH_SHORT).show(); ` return value of textview but i cant add this textview in linearlayout — Farhad Aghajanian, Nov 22 '16 at 19:18
