How to make LinearLayouts clickable

I have a layout which is inherited from LinearLayout, I have this Custom View on MainActivity.

My problem is the OnLongTouch won't work when I put this Custom View on an Activity and it seems my custom view is not clickable!

Layout code:

public class AliLayout extends LinearLayout {

    public AliLayout(Context context, AttributeSet attrs) {
        super(context, attrs);



        if(! isInEditMode()){

            final AliLayout ly2 = this;//(AliLayout)findViewById(R.layout.ali_layout);


            ly2.setOnLongClickListener(new View.OnLongClickListener() {

                @Override
                public boolean onLongClick(View arg0) {
                    // TODO Auto-generated method stub
                    ly2.setTitle("Hello world!");
                    return false;
                }
            });     

        }
    }

    @Override
    protected void onFinishInflate() {
        super.onFinishInflate();
        LayoutInflater.from(this.getContext()).inflate(R.layout.ali_layout,
                this);

    }


    public void setTitle(String txt) {
        TextView tv = (TextView) findViewById(R.id.textView1);
        tv.setText(txt);
    }

}

inflated xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/layout1"
    android:layout_width="200dp"
    android:layout_height="200dp"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:layout_marginBottom="68dp"
    android:layout_marginLeft="40dp"
    android:background="#E0D641"
    android:clickable="true"
    android:longClickable="true"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Large Text"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Large Text"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button" />

</LinearLayout>

MainActivity:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:clickable="true"
    android:longClickable="true"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <com.example.component.AliLayout
        android:id="@+id/ali1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_marginTop="22dp" >
    </com.example.component.AliLayout>

</RelativeLayout>

layout.setclickble="true" in XML file and

layout.setOnLongClickListener(new View.OnLongClickListener() {
    @Override
    public boolean onLongClick(View arg0) {
        // TODO Auto-generated method stub     
    }
});

After trying and failing for hundred times I found the solution to my problem!

Instead of:

ly2.setOnLongClickListener(new View.OnLongClickListener() {

                @Override
                public boolean onLongClick(View arg0) {
                    // TODO Auto-generated method stub
                    ly2.setTitle("Hello world!");
                    return false;
                }
            });

I should have written:

this.setOnLongClickListener(new OnLongClickListener() {

        @Override
        public boolean onLongClick(View arg0) {
            // TODO Auto-generated method stub
            setTitle("Hello World");
            return true;
        }
    });

And I shouldn't have used android:clickable and android:longClickable for inflated XML(ali_layout.xml):

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/layout1"
    android:layout_width="200dp"
    android:layout_height="200dp"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:layout_marginBottom="68dp"
    android:layout_marginLeft="40dp"
    android:background="#E0D641"
    android:orientation="vertical" >

Finally, the problem solved ...

I am answering the question of title, you can use two options for xml and code:

Put in the xml:

android:clickable="true"

Or in .java 

 yourLinearLayout.setClickable(true);

The problem is that your layout is not filling the screen at all since you are using wrap_content with no content in it:

switch your layout to 

 <com.example.component.AliLayout
    android:id="@+id/ali1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_alignParentTop="true"
    android:layout_marginTop="22dp" >
</com.example.component.AliLayout>
