忘れないように、よく使う小さな方法をメモしておきます

1.Activityをダイアログモードに設定
例:

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

2.Activityの進捗バーの設定

protected void onCreate(Bundle savedInstanceState) {
	// TODO Auto-generated method stub
	super.onCreate(savedInstanceState);
	requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
	setContentView(R.layout.loading);
}

setProgressBarIndeterminateVisibility(true);   //  
setProgressBarIndeterminateVisibility(false);  //  

3.Activity間でのデータ転送

//   activity,  
	Intent i = new Intent();
	i.setClass(LoadingActivity.this, DetailsInfo.class);
	Bundle bundle = new Bundle(); 
	bundle.putString("xml", strXML);		//xml      ，      activity
	i.putExtras(bundle);
	startActivity(i);
//   activity,  
public void onCreate(Bundle savedInstanceState)
{
        super.onCreate(savedInstanceState);
        
        Bundle bunde = this.getIntent().getExtras();
        String strXML = bunde.getString("xml"); 
}

4.int String間の変換

  // String   int
    int i = Integer.parseInt([String]);    
    i = Integer.parseInt([String],[int radix]); 

    int i = Integer.valueOf(my_str).intValue(); 
  
  // int   String
    String s = String.valueOf(i); 
    String s = Integer.toString(i);  
    String s = "" + i; 

5.HttpURLConnection接続タイムアウト設定

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();
}
