package com.example.sfgsfg;

import java.io.InputStream;
import java.net.URL;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.entity.BufferedHttpEntity;
import org.apache.http.impl.client.DefaultHttpClient;

import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.widget.ImageView;

public class MainActivity extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ImageView img = (ImageView) findViewById(R.id.imageView1);
try {
URL url = new URL(
"http://0.tqn.com/d/webclipart/1/0/5/l/4/floral-icon-5.jpg");
// try this url =
//"http://0.tqn.com/d/webclipart/1/0/5/l/4/floral-icon-5.jpg"
HttpGet httpRequest = null;

httpRequest = new HttpGet(url.toURI());

HttpClient httpclient = new DefaultHttpClient();
HttpResponse response = (HttpResponse) httpclient
.execute(httpRequest);

HttpEntity entity = response.getEntity();
BufferedHttpEntity b_entity = new BufferedHttpEntity(entity);
InputStream input = b_entity.getContent();

Bitmap bitmap = BitmapFactory.decodeStream(input);

img.setImageBitmap(bitmap);

} catch (Exception ex) {

}

}

}

这是我最近的尝试，我已经尝试了以下所有方法：
在 ImageView 中显示图像(来自 Url)
Android，在等于 ImageView\\ 的图像的 URL 处制作图像
如何在 Android 中通过 URL 加载 ImageView？
如何从 url 为 imageView 设置图像
Android 应用显示来自 URL

的图像

没有任何作用！而且我需要它而不使用 AsyncTask！请帮忙！
