android including one layout with different IDs

Question

I have created a layout with an ImageView, I want to include it two times with two different ImageView like a ListView with different positions.

this is the ImageView layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">

    <include
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        layout="@layout/main_guilds_item"
        android:layout_gravity="center_horizontal" />

    <include
        layout="@layout/main_guilds_item"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal" />
</LinearLayout>

here i include the layout two times but i want to access those ImageViews with different IDs to set different Images.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout       xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <include
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        layout="@layout/main_guilds_item"
        android:layout_gravity="center_horizontal" />

    <include
        layout="@layout/main_guilds_item"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal" />
</LinearLayout>

How can I do it ?

Please share the code you already have, and if possible a (simple and small) image of what you want to achieve. That way it's easier for the rest of us to help you. — Marcel50506, Aug 31 '16 at 07:35
The two codeblocks you've added are the same. Could you include the 'main_guilds_item' xml layout? — Marcel50506, Aug 31 '16 at 08:14

You can create custom view for this purpose. Steps are

Create a xml file of the view my_custom_view.xml

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<ImageView
    android:id="@+id/image_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/ic_launcher"
    />
</RelativeLayout>

Then you need to create a class ItemList that extends RelativeLayout(the parent layout in your my_custom_view.xml)

public class ItemList extends RelativeLayout {

ImageView mImageView;

public ItemList(Context context) {
this(context, null);
}

public ItemList(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}

public ItemList(Context context, AttributeSet attrs, int defStyle){
super(context, attrs, defStyle);
LayoutInflater.from(context).inflate(R.layout.item_list_content, this);
     mImageView=(ImageView) findViewById(R.id.image_view);
}

public void setImage(Drawable imageId){
mImageView.setImageDrawable(imageId);
}
}

Then you can use this customview in your other layouts as many times as you want like below

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">

    <yourpackage.ItemList
        android:id="@+id/first_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </yourpackage.ItemList>

    <yourpackage.ItemList
        android:id="@+id/second_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </yourpackage.ItemList>

</LinearLayout>

Now from your class you do

ItemList firstItem=(ItemList) findViewById(R.id.first_view);
ItemList secondItem=(ItemList) findViewById(R.id.second_view);
firstItem.setImage(R.drawable.your_image);
secondItem.setImage(R.drawable.your_image_2);

NOTE: You can also take the image from xml. In that case you will have to use custom attribute. Follow the link for that purpose. https://stackoverflow.com/a/7608739/3975838
