LinearLayout dynamically display depending on a given number

I want to create a method that can dynamically display LinearLayout in a LinearLayout moreover that is located in a specified area in my Android application, the number of this linear layout changes depending on a given number.

Also, in each LinearLayout I want to display a Button & below it a TextView.

Here is the method I have already created:

public void putLinearLayout(double number){       int mButtonHeight = 100;        int mButtonWidth = 80;         LinearLayout Linear = (LinearLayout)findViewById(R.id.linearlayout1);        for(int i=1;i<=number;i++)        {            LinearLayout L = new LinearLayout(this);            Button b= new Button(this);            TextView tv = new TextView(this);            L.setOrientation(LinearLayout.HORIZONTAL);            b.setWidth(mButtonWidth);            b.setHeight(mButtonHeight);            L.addView(b);            L.addView(tv);            Linear.addView(L);        }    }

you just need to set the layoutparams

public void putLinearLayout(double number){        LinearLayout Linear = (LinearLayout)findViewById(R.id.linearlayout1);               int mButtonHeight = 100;                int mButtonWidth = 80;                for(int i=1;i<=number;i++)                {                    LinearLayout L = new LinearLayout(this);                    L.setBackgroundColor(Color.WHITE);                    LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT); //<--this line , is what you were missing                    L.setLayoutParams(params); //<-- & then this                    Button b= new Button(this);                    b.setText(i+"");                    TextView tv = new TextView(this);                    tv.setText("i am textview number: "+i);                    L.setOrientation(LinearLayout.HORIZONTAL);                    b.setWidth(mButtonWidth);                    b.setHeight(mButtonHeight);                    L.addView(b);                    L.addView(tv);                    Linear .addView(L);                }

}
