2010.11.27———android 展示网络上的图片和播放视频

1、展示图片： ImageView

layout：

<?xml version="1.0" encoding="utf-8"?><LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android"  android:orientation="vertical"  android:layout_width="wrap_content"  android:layout_height="wrap_content"  >    <ImageView    android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:id="@+id/imageView"    />    </LinearLayout>

PicShowActivity.java

package com.huitu.project;import java.util.List;import android.app.Activity;import android.content.Intent;import android.graphics.Bitmap;import android.graphics.BitmapFactory;import android.os.Bundle;import android.widget.ImageView;import android.widget.TextView;import android.widget.Toast;import com.huitu.pojo.AD_TPXX;import com.huitu.service.PicService;import com.huitu.util.ImageUtil;import com.huitu.util.JSONUtil;public class PicShowAcitivity extends Activity {private ImageView iv;//private TextView title;//private TextView desc;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.picshow);iv = (ImageView)findViewById(R.id.imageView);//title = (TextView)findViewById(R.id.pic_show_title);//desc = (TextView)findViewById(R.id.pic_show_desc);//Intent intent = this.getIntent();//int id = intent.getIntExtra("id", 0);try {String json = PicService.query(id);if(!json.trim().equals("noValue")){List<AD_TPXX> list = JSONUtil.parseJSON_Pic_list(json);AD_TPXX bean = list.get(0);desc.setText(bean.getDescr());//图片的地址XXX/1.jpgString path = "http://10.169.53.126:8080/CPJW_2"+bean.getPath();path = path.replace("\\", "/");System.out.println(path);//得到图片的字节流 然后把图片画到手机上byte[] data = ImageUtil.getImage(path);System.out.println(data.length);Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);iv.setImageBitmap(bitmap);}else{Toast.makeText(this, R.string.pic_show_error, 0).show();}} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}}}

ImageUtil.java

package com.huitu.util;import java.io.InputStream;import java.net.HttpURLConnection;import java.net.URL;public class ImageUtil {public static byte[] getImage(String path) throws Exception{URL url = new URL(path);HttpURLConnection conn = (HttpURLConnection) url.openConnection();conn.setConnectTimeout(5*1000);conn.setRequestMethod("GET");if(conn.getResponseCode()==200){InputStream inStream = conn.getInputStream();byte[] data = StreamTool.readStream(inStream);return data;}return null;}}

2、播放网络上的视频

layout.xml : VideoView

<?xml version="1.0" encoding="utf-8"?><LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android"  android:orientation="vertical"  android:layout_width="wrap_content"  android:layout_height="wrap_content"  >      <LinearLayout     android:orientation="horizontal"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:paddingTop="68px"    >    <TextView      android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:text="@string/video_show_desc"    /> <TextView      android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:id="@+id/video_show_desc"    />     </LinearLayout>    <VideoView    android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:id="@+id/videoView"    android:paddingTop="10px"    />    </LinearLayout>

VideoShowActivity.java

package com.huitu.project;import java.util.List;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.widget.MediaController;import android.widget.TextView;import android.widget.Toast;import android.widget.VideoView;import com.huitu.pojo.AD_SPXX;import com.huitu.service.VideoService;import com.huitu.util.JSONUtil;public class VideoShowAcitivity extends Activity {private VideoView vv;private TextView desc;//private MediaPlayer player;private MediaController control;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.videoshow);vv = (VideoView)findViewById(R.id.videoView);desc = (TextView)findViewById(R.id.video_show_desc);Intent intent = this.getIntent();int id = intent.getIntExtra("id", 0);try {String json = VideoService.query(id);if(!json.trim().equals("noValue")){List<AD_SPXX> list = JSONUtil.parseJSON_Video_list(json);AD_SPXX bean = list.get(0);desc.setText(bean.getDescr());String path = "http://10.169.53.126:8080/CPJW_2"+bean.getPath();path = path.replace("\\", "/");System.out.println(path);//player = MediaPlayer.create(this, VideoUtil.getVideo(path));vv.setVideoPath(path);control = new MediaController(this);control.setMediaPlayer(vv);vv.setMediaController(control);//.requestFocus();vv.start();}else{Toast.makeText(this, R.string.video_show_error, 0).show();}} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}}}
