常用的小方法，避免忘记，在此记录一下

1. 将Activity设置为对话框模式
例如:

<activity android:name=".DeviceListActivity"                  android:theme="@android:style/Theme.Dialog"                  android:configChanges="orientation|keyboardHidden" />

2. 设置Activity的进度条

protected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);setContentView(R.layout.loading);}setProgressBarIndeterminateVisibility(true);   //打开setProgressBarIndeterminateVisibility(false);  //关闭

3. Activity之间传递数据

//第一个activity,发送Intent i = new Intent();i.setClass(LoadingActivity.this, DetailsInfo.class);Bundle bundle = new Bundle(); bundle.putString("xml", strXML);//xml数据作为参数，传递给另一个activityi.putExtras(bundle);startActivity(i);//第二个activity,接收public void onCreate(Bundle savedInstanceState){        super.onCreate(savedInstanceState);                Bundle bunde = this.getIntent().getExtras();        String strXML = bunde.getString("xml"); }

4. int String 之间的转换

  // String转换为int    int i = Integer.parseInt([String]); 或      i = Integer.parseInt([String],[int radix]);     int i = Integer.valueOf(my_str).intValue();     // int转换为String    String s = String.valueOf(i);     String s = Integer.toString(i);      String s = "" + i;

5. HttpURLConnection连接超时设置

URL url = null;HttpURLConnection urlConn = null;url = new URL(AppConstant.URL.Url_AgtTotalInfo);urlConn = (HttpURLConnection) url.openConnection();urlConn.setConnectTimeout(10 * 1000);System.out.println("time out is 10 seconds");try{if (urlConn.getResponseCode() != 200){throw new SocketTimeoutException("request url failed!");}}catch(SocketTimeoutException e){System.out.println(e);//System.out.println("not connected");urlConn.disconnect();}
