How read ImageView margin programmatically?

I have an ImageView which is written in a layout file and looks like this

<LinearLayout 
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="vertical">

        <ImageView android:id="@+id/news_image" 
            android:layout_height="fill_parent"
            android:layout_width="fill_parent"
            android:layout_marginLeft="18dip"
            android:layout_marginRight="18dip"
            android:background="#aaaaaa" />

</LinearLayout>

How can I read the android:layout_marginLeft attribute in my Activity?

  • I tried this following code but LayoutParams of my ImageView doesn’t have any margin members (like for example LinearLayout.LayoutParams has).

    ImageView imageView = (ImageView)findViewById(R.id.news_image);
    LayoutParams lp = imageView.getLayoutParams();
    
    int marginLeft = lp.marginLeft; // DON'T do this! It will not work 
                                    // cause there is no member called marginLeft
    

    Any suggestions how to get the margin from a ImageView?

    Thank you!

    you have to cast the LayoutParams to the type that is specific to the layout the view is in. That is, being your view inside a LinearLayout, you’ll have to do the following:

    ImageView imageView = (ImageView)findViewById(R.id.news_image);
    LinearLayout.LayoutParams lp =
                    (LinearLayout.LayoutParams) imageView.getLayoutParams();
    

    now lp will let you access margin* fields.

    Your sol for it is as below:


     LinearLayout. LayoutParams lp = (android.widget.LinearLayout.LayoutParams) imageView.getLayoutParams();
    
      int i=lp.leftMargin;
