关于Progressbar的问题

求解这段代码为什么调试不起来，看了半天看不出来，谢谢各位大神了。



public class MainActivity extends ActionBarActivity implements OnClickListener {

	private ProgressBar progressbar;

	private Button add;

	private Button reduce;

	private Button reset;

	private TextView text;



	@Override

	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		requestWindowFeature(Window.FEATURE_PROGRESS);

		requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);

		setContentView(R.layout.activity_main);

		setProgressBarVisibility(true);

		setProgressBarIndeterminateVisibility(false);

		setProgress(9999);

		init();

	}



	private void init() {

		progressbar = (ProgressBar) findViewById(R.id.progress_horizontal);

		add = (Button) findViewById(R.id.add);

		reduce = (Button) findViewById(R.id.reduce);

		reset = (Button) findViewById(R.id.reset);

		text = (TextView) findViewById(R.id.text);

		int first = progressbar.getProgress();

		int second = progressbar.getSecondaryProgress();

		int max = progressbar.getMax();



		text.setText("第一进度的百分比是" + (int) (first / (float) max * 100)

				+ "%  第二进度的百分比是" + (int) (second / (float) max * 100) + "%");

		add.setOnClickListener(this);

		reduce.setOnClickListener(this);

		reset.setOnClickListener(this);

	}



	@Override

	public void onClick(View v) {

		switch (v.getId()) {

		case R.id.add:

			progressbar.incrementProgressBy(10);

			progressbar.incrementSecondaryProgressBy(10);

			break;



		case R.id.reduce:

			progressbar.incrementProgressBy(-10);

			progressbar.incrementSecondaryProgressBy(-10);

			break;

		case R.id.reset:

			progressbar.setProgress(50);

			progressbar.setSecondaryProgress(80);

			break;

		}

		text.setText("第一进度的百分比是"

				+ (int) (progressbar.getProgress()

						/ (float) progressbar.getMax() * 100)

				+ "%  第二进度的百分比是"

				+ (int) (progressbar.getSecondaryProgress()

						/ (float) progressbar.getMax() * 100) + "%");

	}



}
