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);
}
}

If anyone have have idea about this please guide me friends.
If you want to just fit the image in image view you can use" wrap content" in height and width property with scale-type but if you want to set manually you have to use LayoutParams. Layoutparams is efficient for setting the layout height and width programmatically.
To get width and height of ImageView, we can call getWidth() and getHeight(). But it's invalid before the ImageView have been actually drawn. When getWidth() and getHeight() are called in onCreate(), before actually drawn; "0" will be return.
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);
This simple way to do your task:
setContentView(R.id.main);
ImageView iv = (ImageView) findViewById(R.id.left);
int width = 60;
int height = 60;
LinearLayout.LayoutParams parms = new LinearLayout.LayoutParams(width,height);
iv.setLayoutParams(parms);
and another way if you want to give screen size in height and width then use below code :
setContentView(R.id.main);
Display display = getWindowManager().getDefaultDisplay();
ImageView iv = (ImageView) findViewById(R.id.left);
int width = display.getWidth(); // ((display.getWidth()*20)/100)
int height = display.getHeight();// ((display.getHeight()*30)/100)
LinearLayout.LayoutParams parms = new LinearLayout.LayoutParams(width,height);
iv.setLayoutParams(parms);
hope use full to you.
