How to Put a Linear Layout-android

How to Put a Linear Layout

I have created in my file .xml a linear layout
I want to create in this linear layout a linear layout which contains 3 linear layout with this latter contains a button and a text view below
I create a method but it does not display anything:
here's the method :

public void putLinearLayoutProduct(double count){
        LinearLayout Linear = (LinearLayout)findViewById(R.id.linearlayout1);

         int mButtonHeight = 60;//hauteur
         int mButtonWidth = 120;//longueur

        while(count >0)
        {
            LinearLayout L = new LinearLayout(this);
            L.setOrientation(LinearLayout.HORIZONTAL);
            LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT); //<--this line , is what you were missing
            L.setLayoutParams(params);

            for(int i=1;i<=3;i++)
            {
                LinearLayout L1 = new LinearLayout(this);
                L1.setBackgroundColor(Color.WHITE);
                L1.setLayoutParams(params);

                Button b= new Button(this);
                TextView tv = new TextView(this);
                tv.setGravity(Gravity.CENTER);
                tv.setTextColor(Color.BLUE);
                tv.setText("name");
                L1.setOrientation(LinearLayout.VERTICAL);
                b.setWidth(mButtonWidth);
                b.setHeight(mButtonHeight);
                L1.addView(b);
                L1.addView(tv);
                L.addView(L1);
                count --;
            }

            Linear.addView(L);
        }


    }
suspect you are trying to do what a ListView already does. See the developers network article on ListViews. What I would suggest doing is create one Layout for just the inner most LinearLayout (I call this text_and_btton.xml):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    android:gravity="center_horizontal"
    android:orientation="vertical" >

    <Button
        android:id="@+id/button"
        android:layout_width="@dimen/button_width"
        android:layout_height="@dimen/button_height"
        android:text="" />

    <TextView
        android:id="@+id/label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:text="name"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:textColor="@color/blue" />

</LinearLayout>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    android:gravity="center_horizontal"
    android:orientation="vertical" >

</LinearLayout>

Then you define the outer layout with a ListView:

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/image_list"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

</ListView>
<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/image_list"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

</ListView>
Then you make an adapter that basically is a list of the text and images you want to put into the ListView. The adapter creates the 'inner most' of you layouts - the one with the button and text. Here is an example:

public class ImageStuffAdapter extends ArrayAdapter<ImageStuffAdapter.Image>
{
    private static final Image[] images = new Image[]
    {
            new Image("pizza", R.drawable.pizza),
            new Image("fish", R.drawable.fish),
            new Image("boissoins", R.drawable.boissoins)
    };

    public ImageStuffAdapter(Context context)
    {
        super(context, R.id.label);
    }

    @Override
    public int getCount()
    {
        return images.
