android中获取网络图片并展示以及去掉标题

获取网络图片：

?

public static Bitmap returnBitMap(String url) {		URL myFileUrl = null;		Bitmap bitmap = null;		HttpURLConnection conn = null;		try {			myFileUrl = new URL(url);		} catch (MalformedURLException e) {			e.printStackTrace();		}		try {			conn = (HttpURLConnection) myFileUrl.openConnection();			conn.setConnectTimeout(1000);			conn.setDoInput(true);			conn.connect();			InputStream is = conn.getInputStream();			bitmap = BitmapFactory.decodeStream(is);			is.close();		} catch (IOException e) {			e.printStackTrace();		}finally{			if(conn != null){				conn.disconnect();			}		}		return bitmap;	}

?

去掉标题，只需要在androidmanifest.xml配置文件中添加一个主题信息就可以了：

  android:theme="@android:style/Theme.NoTitleBar"
