本org.apache.http类和AndroidHttpClient类已经被弃用的Android 5.1.这些类不再被维护,您应该尽快使用这些API将任何应用程序代码迁移到URLConnection类.

https://developer.android.com/about/versions/android-5.1.html#http

它建议切换到URLConnection类.没有足够的文件记录如何从应用程序进行发布呼叫.

目前我正在使用这个

public void postData()
{
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");

    try
    {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair(2);
        nameValuePairs.add(new BasicNameValuePair("id", "12345"));
        nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);
     } 
     catch (ClientProtocolException e) 
     {
        // TODO Auto-generated catch block
     } 
     catch (IOException e) 
     {
        // TODO …

我有一个ListView.我更新了它的适配器,然后打电话notifydatasetchanged().我想等到列表完成绘制,然后调用列表上的getLastVisiblePosition()来检查最后一项.

调用getLastVisiblePosition()之后notifydatasetchanged()不起作用,因为列表处理不当画完呢.

由于某些特定原因,我正在制作一个使用谷歌地图的应用程序.所以我在Android Studio中创建了一个Google Maps应用程序,我得到了一个扩展FragmentActivity的活动.一切都很完美,但现在我想在屏幕顶部添加操作栏.问题是地图占据了整个屏幕,我不知道如何修复它

这是我的活动代码:

public class MainActivity extends FragmentActivity implements LocationListener {
    private GoogleMap mMap; // Might be null if Google Play services APK is not available.
    double lon = 0;
    double lat = 0;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        setUpMapIfNeeded();

    }
    @Override
    protected void onResume() {
        super.onResume();
        setUpMapIfNeeded();
    }
    public void showSettingsAlert(){
        AlertDialog.Builder alertDialog = new AlertDialog.Builder(this);

        // Setting Dialog Title
        alertDialog.setTitle("GPS settings");

        // Setting Dialog Message
        alertDialog.setMessage("GPS is not enabled. Do you want to go …

我正在使用mcxiaoke/android-volley库.我得到了编译错误

Error:(77, 37) error: reference to JsonObjectRequest is ambiguous, both constructor 
JsonObjectRequest(int,String,String,Listener<JSONObject>,ErrorListener) in JsonObjectRequest and constructor 
JsonObjectRequest(int,String,JSONObject,Listener<JSONObject>,ErrorListener) in JsonObjectRequest match

这是我的代码.我不知道有什么问题.任何帮助赞赏

JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET,
            getRequestUrl(10),
            null,
            new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {


        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {

        }
    });

我使用过与Google BLE不兼容的设备,而是使用Samsung BLE SDK进行连接.我已尝试使用Google SDK,它可以成功连接,但在连接后立即与状态19断开连接,其中没有此状态所需的文档.

我从Tizen网站下载了SDK映像,在安装管理器的帮助下,我尝试安装Tizen SDK但失败了.我完全无法解决这个问题.我验证了下载软件包的MD5哈希值,它与网站中提到的相同.我也选择从网上安装它.出于同样的原因,它也失败了.

它在安装Intel haxm软件包时显示错误.安装提示输入密码并且已正确提供,但安装失败.

这是日志

我在 Nexus 7 第一代而不是模拟器上测试了这些代码。在网上完整搜索后，我找到了类似问题的解决方案，并添加了权限INTERNET和ACCESS_NETWORK_STATE，但仍然出现此错误。

我使用以下代码来播放gif,但在这里它继续重复gif播放.

Uri uri;
DraweeController controller = Fresco.newDraweeControllerBuilder()
    .setUri(uri)
    .setAutoPlayAnimations(true)
    . // other setters
    .build();
mSimpleDraweeView.setController(controller);

我该怎么玩一次？
