[android] Change background of LinearLayout in Android

I am working on an Android application. I want to change the background of a LinearLayout element.

What attribute can I set in order to change its background?

u just used attribute

• android:background="#ColorCode" for colors

  if your image save in drawable folder then used :-

• android:background="@drawable/ImageName" for image setting

1- Select LinearLayout findViewById

LinearLayout llayout =(LinearLayout) findViewById(R.id.llayoutId); 

2- Set color from R.color.colorId

llayout.setBackgroundColor(getResources().getColor(R.color.colorId));

 android:background="@drawable/ic_launcher"

should be included inside Layout tab. where ic_launcher is image name that u can put inside project folder/res/drawable . you can copy any number of images and make it as background

If your using a background resource and wish to change the resource out you can use setBackgroundResource() function.

ui_item.setBackgroundResource(R.drawable.myResource)

A background resource in XML would look like:

<LinearLayout
                android:id="@+id/ui_item"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="@drawable/background_01"
                android:orientation="vertical">

Use this code, where li is the LinearLayout: li.setBackgroundColor(Color.parseColor("#ffff00"));

LinearLayout li=(LinearLayout)findViewById(R.id.layoutid);

setting the background color fro ur layout.

li.setBackgroundColor(Color.parseColor("#ffff00"));

this is to set the image which u can store in drawable folder

li.setBackgroundDrawable(drwableItem);

some resource for display purpose animation or img

li.setBackgroundResource(R.id.bckResource);
