I followed Android recommendation and set style="?android:attr/buttonBarStyle" to parent layout and style="?android:attr/buttonBarButtonStyle" to buttons.

So now my layout is something like this:

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="horizontal"

style="?android:attr/buttonBarStyle">

android:id="@+id/button1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="Button 1"

style="?android:attr/buttonBarButtonStyle"/>

android:id="@+id/button2"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="Button 2"

style="?android:attr/buttonBarButtonStyle"/>

android:id="@+id/button3"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="Button 3"

style="?android:attr/buttonBarButtonStyle"/>

But after setting the style, these buttons have become invisible, although I can still click on them.

Please tell me what is wrong.

Edit: Additional details

Well, I've just created a new project specifically to test this layout and surprisingly it indeed does work.

So to be more precise, actually, I dynamically add this layout to another one, something like this:

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical">

android:id="@+id/buttons_panel_container"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:orientation="horizontal">

Code:

LayoutInflater layoutInflater = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);

LinearLayout buttonsPanelContainer = (LinearLayout) findViewById(R.id.buttons_panel_container);

View buttonPanelView = null;

if(chosenValueType.equals("some_type")) {

buttonPanelView = layoutInflater.inflate(R.layout.some_buttons_panel, null);

Button Button1 = (Button) buttonPanelView.findViewById(R.id.button1);

Button1.setOnClickListener(this);

Button Button2 = (Button) buttonPanelView.findViewById(R.id.button2);

Button2.setOnClickListener(this);

} else if (chosenRawValueType.equals("another_type") {

//...

ViewGroup insertPoint = (ViewGroup) buttonsPanelContainer;

insertPoint.addView(buttonPanelView, 0, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));

Sorry to not mention it earlier, I didn't think it could be the case.

So what's wrong?
