How to set Height Width of ImageView programmatically in android?

Question

How to increase or decrease the size of imageview,textview or anyother by programmatically in linear layout in getview() of slide menu.

I got slide menu through androidhive tutorials

Exactly in slide menu I need to add a user profile pic and his name ,location as like in facebook,google and other social sites for this tried a lot with (getlayoutparams(),setheight()...) even though with a lot of method but I can't set it in side menu list.

What ever method but no changes in the profile pic and name.

Here is my code:

mport android.annotation.SuppressLint;
import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.ViewGroup.LayoutParams;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;

public class NavDrawerListAdapter extends BaseAdapter {
ImageView imgIcon;
LinearLayout linearposition;
private Context context;
private ArrayList<NavDrawerItem> navDrawerItems;

public NavDrawerListAdapter(Context context,
ArrayList<NavDrawerItem> navDrawerItems) {
this.context = context;
this.navDrawerItems = navDrawerItems;
}

@Override
public int getCount() {
return navDrawerItems.size();
}

@Override
public Object getItem(int position) {
return navDrawerItems.get(position);
}

@Override
public long getItemId(int position) {
return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.drawer_list_item, null);

linearposition = (LinearLayout) convertView
.findViewById(R.id.linearposition);
}
NavDrawerItem label = navDrawerItems.get(position);
if (position == 0) {
newsection(linearposition, label);
}
imgIcon = (ImageView) convertView.findViewById(R.id.icon);
TextView txtTitle = (TextView) convertView.findViewById(R.id.title);
TextView txtCount = (TextView) convertView.findViewById(R.id.counter);

imgIcon.setImageResource(navDrawerItems.get(position).getIcon());
txtTitle.setText(navDrawerItems.get(position).getTitle());

// displaying count
// check whether it set visible or not
if (navDrawerItems.get(position).getCounterVisibility()) {
txtCount.setText(navDrawerItems.get(position).getCount());
} else {
// hide the counter view
txtCount.setVisibility(View.GONE);
}

return convertView;
}

@SuppressLint("NewApi"
private void newsection(LinearLayout linearposition, NavDrawerItem label) {
// int height = 50;
// int width =50;
ImageView image = new ImageView(context);
// image.setImageResource(R.drawable.profile_circle);
// image.setPaddingRelative (5, 5, 5, 5);
// image.setMaxHeight(40);
// image.setMaxWidth(40);
// image.getLayoutParams().height = 20;
// image.requestLayout();
android.view.ViewGroup.LayoutParams layoutParams = image
.getLayoutParams();
layoutParams.width = 20;
layoutParams.height = 20;
image.setLayoutParams(layoutParams);
linearposition.addView(image);

// android.view.ViewGroup.LayoutParams layoutParams =
// image.getLayoutParams();
// LinearLayout.LayoutParams layoutParams = new
// LinearLayout.LayoutParams(0, 0);
// image.setLayoutParams(layoutParams);
// layoutParams.width = 30;
// layoutParams.height = 30;
// image.setLayoutParams(new LayoutParams(width,height));
// LinearLayout.LayoutParams layoutParams = new
// LinearLayout.LayoutParams(100, 100);
// iv.setLayoutParams(layoutParams);
// image.setLayoutParams(layoutParams);
// linearposition.addView(image);

}
}

Layout:

 <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="48dp"
    android:background="@drawable/list_selector" >

    <LinearLayout
        android:id="@+id/linearposition"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        androidrientation="vertical" />

    <ImageView
        android:id="@+id/icon"
        android:layout_width="25dp"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_centerVertical="true"
        android:layout_marginLeft="12dp"
        android:layout_marginRight="12dp"
        android:contentDescription="@string/desc_list_item_icon"
        androidrc="@drawable/home_icon" />

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_toRightOf="@id/icon"
        android:gravity="center_vertical"
        android:minHeight="?android:attr/listPreferredItemHeightSmall"
        androidaddingRight="40dp"
        android:textAppearance="?android:attr/textAppearanceListItemSmall"
        android:textColor="@color/list_item_title" />

    <TextView
        android:id="@+id/counter"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:layout_marginRight="8dp"
        android:background="@drawable/counter_bg"
        android:textColor="@color/counter_text_color" />

</RelativeLayout>

If anyone have have idea about this please guide me friends.

To Set Width and Height Programmetically and make sure that you have not given fixed width and height to the parent layout of imageview

android.view.ViewGroup.LayoutParams layoutParams = imageView.getLayoutParams();
layoutParams.width = 80;
layoutParams.height = 80;
imageView.setLayoutParams(layoutParams);
