android中获取网络图片并显示以及去掉标题

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"
