Receive a long press/click on a linear layout in android? - android-layout

Question

I'm painfully new to android and I've run into a wall.
I'm trying get a linear layout to function more like a button, with different actions for press and long press - The reason being so I can have 2 differently formatted text labels on each "button". Something along the lines of:
-------------------------
| 2nd | <- Label for long press (regular/smaller type)
| = | <- Label for regular press (bold/larger type)
-------------------------
The posts I've found explain how to receive a regular click on a linear layout (I use the onClick attribute in the layout XML). But I've had no luck with long press. I've tried to define a new onLongClick attribute for xml as described in Aleksander Gralak's answer here: Long press definition at XML layout, like android:onClick does . But had no such luck - it looks like it was intended for a text view, I tried changing it to linear layout but failed miserably.
Here is the object in question: Main.xml
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:clickable="true"
android:focusable="true"
android:background="#drawable/darkgrey_button"
android:onClick="equals" android:longClickable="true" android:id="equalsbutton"
android:focusableInTouchMode="false">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="2nd"
android:id="#+id/textView"
android:duplicateParentState="true"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" = "
android:id="#+id/textView1"
android:duplicateParentState="true"/>
</LinearLayout>
And Main.java
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void equals(View view) {
Context context = getApplicationContext();
CharSequence text = "Hello toast!";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
}

Answer 1

Add an id to your layout.
<LinearLayout
android:id="#+id/my_button_layout"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
… >
In your Main.java
Get a reference to your LinearLayout and set a OnLongClickListener.
LinearLayout buttonLayout = (LinearLayout) findViewById(R.id.my_button_layout);
…
buttonLayout.setOnLongClickListener(new OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
Toast.makeText(Main.this, "Long click!", Toast.LENGTH_SHORT).show();
return true;
}
});
