<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical"
          android:focusable="false"
          android:layout_width="fill_parent"

Before some days i have face same problem. But now i have solve it.

Do like following.

Make One class called DontPressWithParentButton which extends Button like below:

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.Button;

public class DontPressWithParentButton extends Button {

    public DontPressWithParentButton(Context context) {
        super(context);
    }

    public DontPressWithParentButton(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public DontPressWithParentButton(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public void setPressed(boolean pressed) {
        if (pressed && getParent() instanceof View && ((View) getParent()).isPressed()) {
            return;
        }
        super.setPressed(pressed);
    }

}

Now, in your item row xml, define Button as like below (add your package in place of YOUR_APP_PACKAGE)

<YOUR_APP_PACKAGE.DontPressWithParentButton android:id="@+id/deleteBtn" android:layout_width="100dp"
            android:layout_height="wrap_content" android:layout_alignParentRight="true"
            android:textColor="#FFFFFF"
            android:text="Approve"
            android:focusable="false"
            android:focusableInTouchMode="false"
            />

Now reference id in your java file like below:

DontPressWithParentButton deleteGameBtn=(DontPressWithParentButton) findViewById(R.id.deleteGameBtn);

Now run the project. You will get what you want.

comment me if you have any query.

public class DontPressWithParentButton extends Button {

public DontPressWithParentButton(Context context) {
    super(context);
}

public DontPressWithParentButton(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public DontPressWithParentButton(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

@Override
public void setPressed(boolean pressed) {
    if (pressed && getParent() instanceof View && ((View) getParent()).isPressed()) {
        return;
    }
    super.setPressed(pressed);
}
}

Add the following element in layout file

<DontPressWithParentButton />

Hope this works fine without any flaws

Add android:descendantFocusability="blocksDescendants" so that child View(row ) can be blocked.

<ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:descendantFocusability="blocksDescendants" />

And if you want the vise wersa than add focusable and focusableInTouchMode to false to imageButton/Button in item.xml
