参看以下代码：
public class ProgressActivity extends Activity implements OnClickListener { // 最大进度 private static final int MAX_PROGRESS = 100; // 进度条 private ProgressDialog progressDialog; // 当前进度值 private int progress = 0; // 控件 private Button btn_progress_1; private Button btn_progress_2; private Handler handler = new Handler() { @Override public void handleMessage(Message msg) { super.handleMessage(msg); switch (msg.what) { case 1: if (progress > MAX_PROGRESS) {// 达到最大值 progress = 0; progressDialog.dismiss(); } else { progress++; // 进度递增1 progressDialog.incrementProgressBy(1); handler.sendEmptyMessageDelayed(1, 50 + new Random().nextInt(500)); } break; default: break; } } }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_progress); initViews(); initListeners(); } private void initViews() { btn_progress_1 = (Button) findViewById(R.id.btn_progress_1); btn_progress_2 = (Button) findViewById(R.id.btn_progress_2); } private void initListeners() { btn_progress_1.setOnClickListener(this); btn_progress_2.setOnClickListener(this); } /** * 显示对话框 */ @SuppressWarnings("deprecation") private void showProgressDialog(int style) { progressDialog = new ProgressDialog(this); progressDialog.setIcon(R.drawable.ic_launcher); progressDialog.setTitle("正在处理数据..."); progressDialog.setMessage("请稍后..."); // 设置进度对话框的风格 progressDialog.setProgressStyle(style); // 设置进度对话框的进度最大值 progressDialog.setMax(MAX_PROGRESS); // 设置进度对话框的“暂停”按钮 progressDialog.setButton(DialogInterface.BUTTON_POSITIVE, "暂停", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { handler.removeMessages(1); } }); // 设置进度对话框的“取消”按钮 progressDialog.setButton(DialogInterface.BUTTON_NEUTRAL, "取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { handler.removeMessages(1); // 重置 progress = 0; progressDialog.setProgress(progress); } }); progressDialog.show(); progress = (progress > 0) ? progress : 0; progressDialog.setProgress(progress); handler.sendEmptyMessage(1); } @Override public void onClick(View v) { switch (v.getId()) { case R.id.btn_progress_1:// 进度对话框 showProgressDialog(ProgressDialog.STYLE_HORIZONTAL); break; case R.id.btn_progress_2:// 旋转对话框 showProgressDialog(ProgressDialog.STYLE_SPINNER); break; default: break; } }}转载请注明出处：http://blog.csdn.net/hai_qing_xu_kong/article/details/45024997 情绪控_
