Dynamically created Linear Layout does not wrap content

Question

I am trying to dynamically add textviews inside a LinearLayout. once all the width of all the textviews is bigger than the width of the screen I need to create another LinearLayout below the first one and continue adding textviews. I am basically splitting a String into multiple textviews, because I need to check if some of the words have a '#' in front. If so I need to change the color. The problem I am having is that the first LinearLayout is very tall (Height does not wrap content). Any help?

LinC is is the linearLayout counter. It get incremented once the widths of the textviews is greater than the screen

        public void TextMod()
{
    LinearLayout.LayoutParams layoutParams,layoutParams2;
    layoutParams= new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
    layoutParams= new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
    llay= new LinearLayout(this.c);
    llay.setOrientation(LinearLayout.HORIZONTAL);
    llay.setBackgroundColor(Color.GREEN);
    llay2= new LinearLayout(this.c);
    llay2.setBackgroundColor(Color.MAGENTA);
    llay2.setOrientation(LinearLayout.HORIZONTAL);
    Boolean addl =true;
        String parts[]= this.Dis.split(" ");
        size=parts.length;
        int i=0;
        while( i<size)
        {
            //
            if(textview_wid < this.w )
            {
                TextView valueTV = new  TextView(c);
                String d= parts[i] + " ";
                valueTV.setText(d);
                valueTV.measure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED);      
                 textview_wid +=valueTV.getMeasuredWidth();
                 Log.d(" des", " TEEXT WIDTH " +  valueTV.getMeasuredWidth());
                if(d.charAt(0)=='#') 
                {
                    valueTV.setTextColor(Color.MAGENTA);
                }
                if(addl)
                {
                     if(LinC==0)
                     {
                        llay.setLayoutParams(layoutParams);
                        this.Lin.addView(llay);
                     }
                     if(LinC==1)
                     {
                        llay2.setLayoutParams(layoutParams);
                        this.Lin.addView(llay2);
                     }



                    addl=false;

                }

                 valueTV.setLayoutParams(layoutParams);

                if(LinC==0)llay.addView(valueTV);
                if(LinC==1)llay2.addView(valueTV);
                i++;
            }
            else
            {

                Log.d(" des", " TOTAL TEXTVIE WIDE " + textview_wid);
                textview_wid =0;
                LinC++;
                addl=true;

            }


         //   valueTV.setLayoutParams(layoutParams);




        }

}

OnCreate

            @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    DisplayMetrics metrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(metrics);

     height =metrics.heightPixels;
     width=metrics.widthPixels;
    L=(LinearLayout)findViewById(R.id.ll);

    //layoutParams= new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);

    sep = new DescriptionStringSep(s,L,this,width);
    sep.TextMod();


}

</LinearLayout>

What you're doing wrong

setContentView(R.layout.activity_main);

This sets the content view to the xml layout passed as a parameter. Since you're creating a dynamic layout in the TextMod method, call it later on in your code and set the resultant layout in your activity. You should do this

onCreate(){
    ...
    LinearLayout mLayout;
    mLayout = sep.TextMod(); // make TextMod return the root view
    setContentView(mLayout);
}
