Android本地视频播放器开发--搜索本地视频（2）

1、首先介绍布局代码，主布局代码只含有一个LIstView --jie_video.xml

[html]
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >
    <ImageView
        android:layout_width="120dp"
        android:layout_height="80dp"
        android:id="@+id/video_img"
        android:contentDescription="@string/cont"
        />
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_toRightOf="@id/video_img"
        android:layout_alignBottom="@id/video_img"
        >
        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/video_title"
            android:gravity="center"
            android:layout_marginTop="5dp"
            android:text="@string/title"
        />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/video_time"
            android:gravity="center"
            android:layout_alignParentBottom="true"
            android:layout_marginBottom="5dp"
            android:text="@string/time"
        />
    </RelativeLayout>
</RelativeLayout>

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >
    <ImageView
        android:layout_width="120dp"
        android:layout_height="80dp"
        android:id="@+id/video_img"
        android:contentDescription="@string/cont"
        />
    <RelativeLayout
        android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:layout_toRightOf="@id/video_img"
     android:layout_alignBottom="@id/video_img"
        >
        <TextView
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:id="@+id/video_title"
      android:gravity="center"
      android:layout_marginTop="5dp"
      android:text="@string/title"
     />

  <TextView
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:id="@+id/video_time"
      android:gravity="center"
      android:layout_alignParentBottom="true"
      android:layout_marginBottom="5dp"
      android:text="@string/time"
     />
    </RelativeLayout>
</RelativeLayout>
3、布局都写好了，然后就是Activity的编写，这里涉及到视频的缩略图的显示，所以要用到异步加载功能

JieVideo.java

[java]
package com.zhangjie.graduation.videopalyer;

import java.util.List;

import com.zhangjie.graduation.videopalyer.component.JieVideoListViewAdapter;
import com.zhangjie.graduation.videopalyer.component.LoadedImage;
import com.zhangjie.gra
