Custom Buttons - Error in Java - widget.Button; - android-widget

Question

Followed example to the letter. When I try to use a custom button via a custom.xml, emulator crashes with a Java error - inflating class android.widget.Button.

public class MasterActivity extends Activity {
Button uccBtn, tipBtn;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_master);
uccBtn = (Button) findViewById(R.id.button1);

uccBtn.setOnClickListener (uccApp);
tipBtn.setOnClickListener (tipApp);

If I reference just the button by name (btn_ecolab), it works fine, just no animation of the buttons when pressed or selected. I've tried it with a LinearLayout to make sure that the Relitavelayout was not the problem. The custom buttons are in my Res/drawable-hpdi folder. Also tried copies of buttons and custom.xml in the -mdpi, -xhdpi and -xxhdpi. Tried without #string assignments.

try this one.
uccBtn = (Button) findViewById(R.id.button1);
tipBtn = (Button) findViewById(R.id.button2);
uccBtn.setOnClickListener (new OnClickListener() {
#Override
public void onClick(View v) {
//your code is here
}
});
make one folder drawable in res folder put your custom.xml
I am using this way and work great.
