Setting attribute of child element of included layout

Question

I have a main.xml file describing the layout of my main activity:

Answer 1

It is possible if you enable data binding:

In reuse_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">
    <data>
       <variable name="text" type="String"/>
    </data>
    <LinearLayout 
        android:id="@+id/mylayout"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/textView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@{text}" />

        <Button
            android:id="@+id/button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

    </LinearLayout>
</layout>

when you call the reuse_layout.xml just add app:text attribute with it

<layout="@layout/reuse_layout" app:text="some tex" />

You can set the android:id property of each include. That gives the id to the root element of the layout being included.

Get that view by id then find the subview you want to change the text on.

Answer 3

No, there is no way to pass parameters to the included layout other than the layout params using the <include> directive.

You can inflate the layout programatically and add them to your view. Add an id to the container in your main layout:

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

Then in your Activity:

ViewGroup container = (ViewGroup)findViewById(R.id.container);
for (int i = 0; i < 6; i++) {
    View myLayout = getLayoutInflater.inflate(R.layout.mylayout, null);
    TextView tv = myLayout.findViewById(R.id.textView);
    tv.setText("my layout " + i);
    container.addView(myLayout); // you can pass extra layout params here too
}
