我使用下面的代码从网址获取图像,但它不适用于大图像.

在获取该类型的图像时我是否遗漏了一些东西？

imgView = (ImageView)findViewById(R.id.ImageView01);
  imgView.setImageBitmap(loadBitmap("http://www.360technosoft.com/mx4.jpg"));

  //imgView.setImageBitmap(loadBitmap("http://sugardaddydiaries.com/wp-content/uploads/2010/12/how_do_i_get_sugar_daddy.jpg"));

  //Drawable drawable = LoadImageFromWebOperations("http://www.androidpeople.com/wp-content/uploads/2010/03/android.png");
  //imgView.setImageDrawable(drawable);

提前致谢...

即时通讯使用此代码在http请求中设置http标头验证网址..

但我觉得有些什么是因为我无法得到回应......

响应仍然像"需要授权"......

httpParameters = new BasicHttpParams();
String auth = android.util.Base64.encodeToString(
    ("florin999@zitec.ro" + ":" + "test2323" + ":" + "zitec"
    + ":" + "7716099f468cc71670b68cf4b3ba545c5760baa7")
    .getBytes("UTF-8"), android.util.Base64.NO_WRAP);

HttpConnectionParams.setSoTimeout(httpParameters, 0);
client = new DefaultHttpClient(httpParameters);
String getURL = "URL here";
get = new HttpGet(getURL);
get.addHeader("Authorization", "Basic "+ auth);
// get.addHeader("X-ZFWS-Accept", "text/json");

HttpResponse responseGet = client.execute(get);
HttpEntity resEntityGet = responseGet.getEntity();
if (resEntityGet != null) {
    //do something with the response
    //Toast.makeText(Login.this.getApplicationContext(),EntityUtils.toString(resEntityGet), Toast.LENGTH_SHORT).show();
    String s = EntityUtils.toString(resEntityGet);
    tv1.setText(s);
}
}catch(Exception e){
}

plssss尽快帮助我

我在点击TabActivity当前选中的标签时尝试获取Click事件.

我尝试下面的代码,但当我点击一个选项卡时,其他选项卡无法正常工作/单击.

    setupTab(new TextView(this), "Map");
    setupTab(new TextView(this), "Attacks");

我为不同的屏幕尺寸制作了一个动态布局的应用程序.

除320x240屏幕外,它还适用于所有屏幕尺寸.

我使用相同的代码来获取所有的宽度和高度,它也返回正确的值,但它没有返回正确的值,手动创建模拟器意味着320x240和240x400.

我使用了以下代码:

DisplayMetrics metrics = new DisplayMetrics();
WindowManager manager = (WindowManager)getSystemService(Context.WINDOW_SERVICE);

manager.getDefaultDisplay().getMetrics(metrics);

int width=metrics.widthPixels;
int height=metrics.heightPixels;

我目前正在处理一个应用程序..在该应用程序中我必须使用get和post两种方法.. get方法正常工作但在post方法突然我得到响应像

   "invalid method.post required"..

我的代码是:

     String list_url = "************************";
    try {

        String appand = TimeStampForAuth.TimeStameMethod(main.this);
        String auth = android.util.Base64.encodeToString(("iphone" + ":" + 
            "2a5a262d5a")
        .getBytes("UTF-8"), android.util.Base64.NO_WRAP);

        DefaultHttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost(list_url+appand);

        Log.d("URL_LIST", list_url+appand);

        List nvps = new ArrayList();
        nvps.add(new BasicNameValuePair("login",Login));
        nvps.add(new BasicNameValuePair("password",password));
        nvps.add(new BasicNameValuePair("title",title));
        nvps.add(new BasicNameValuePair("category_id",cat_id));




        UrlEncodedFormEntity p_entity = new UrlEncodedFormEntity(nvps,HTTP.UTF_8);
        post.addHeader("Authorization", "Basic " + auth);
        post.setEntity(p_entity);
        HttpResponse response = client.execute(post);
        HttpEntity responseEntity = response.getEntity();
        String s = EntityUtils.toString(responseEntity);
        Log.d("List response", s);

    }
    catch(Exception e){ …

我正在开发一个应用程序，其中我必须根据用户导航旋转箭头。

我正在使用最新的 Mapbox SDK。

我尝试过设置障碍（使用纬度和经度计算）但未能成功。

我不知道如何实现它。

它（箭头标记）应该在预定义的多边形路径上导航。

我已经尝试了将Facebook与XMPP连接起来的所有事情,但我一直只遇到一个错误:
SASL身份验证失败使用机制DIGEST-MD5
我正在实现以下方法来执行此任务:

public class MySASLDigestMD5Mechanism extends SASLMechanism {

public MySASLDigestMD5Mechanism(SASLAuthentication saslAuthentication) {
    super(saslAuthentication);
}

protected void authenticate() throws IOException, XMPPException {
    String[] mechanisms = { getName() };
    Map<String, String> props = new HashMap<String, String>();
    sc = Sasl.createSaslClient(mechanisms, null, "xmpp", hostname, props, this);

    super.authenticate();
}

public void authenticate(String username, String host, String password) throws IOException, XMPPException {
    this.authenticationId = username;
    this.password = password;
    this.hostname = host;

    String[] mechanisms = { getName() };
    Map<String,String> props = new HashMap<String,String>();
    sc = Sasl.createSaslClient(mechanisms, …

我正在一个应用程序中工作,我必须从Facebook获取所有朋友列表.

我已经实现了这样的代码:

Facebook mFacebook = new Facebook("141118172662401");
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(mFacebook);
Bundle params = new Bundle();
params.putString("fields", "name,id");
mAsyncRunner.request("me/friends", params, "GET", new FriendListRequestListener(), null);
    }
});
}

public class FriendListRequestListener {
  public void onComplete(final String response) {
      _error = null;
        try {
            JSONObject json = Util.parseJson(response);
            final JSONArray friends = json.getJSONArray("data");
            FacebookFriendsActivity.this.runOnUiThread(new Runnable() {
                JSONObject data;
                public void run() {
                try{

                    try {
                        data = Util.parseJson(response);
                    } catch (FacebookError e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    JSONArray …

我已经更新了当前的 Play 商店应用程序并启用了即时应用程序功能。但等了5天，仍然没有显示“立即尝试”按钮。

我已经在当前应用程序中实现了即时应用程序功能，并对其进行了更新，如下所示：

1. 在应用程序级 Gradle 中添加了依赖项：实现“com.google.android.gms:play-services-instantapps:17.0.0”
2. 要启用即时应用程序，请右键单击应用程序模块 -> 重构 -> 启用即时应用程序支持。
3. 将版本代码增加到 1 并在 Play 商店上上传新版本。

你们能帮我找出缺失的元素或方向吗？
