我也有微信朋友圈了 Android实现

本文实例分享了一个简单的朋友圈程序，包含了朋友圈的列表实现，视频的录制、预览与上传，图片可选择拍照，供大家参考，具体内容如下

FriendsListActivity  代码如下

public class FriendsListActivity extends baseActivity implements OnRefreshListener, PostListener {

    FriendsApi.getFriendsList(mContext, mCallBack); 
    mRefreshListView.setonRefreshListener(this); 
    mFooter = LayoutInflater.from(mContext).inflate(R.layout.loading_footer, null); 
//   mRefreshListView.getRefreshableView().addFooterView(mFooter); 
    mRefreshListView.setAdapter(mAdapter); 
//   mRefreshListView.setonLastItemVisibleListener(mLastListener); 
//   mRefreshListView.getRefreshableView().setDividerHeight(40); 
    btnToPost.setonClickListener(new onClickListener() { 

      @Override 
      public void onClick(View v) { 
 myPosts(); 
      } 
    }); 
  }

  }

    public void friendslist(ArrayList friends) { 
      Log.i("friends size>>>>",friends.size()+"-------------"); 
      mAdapter.setInteractions(friends); 
//     mRefreshListView.getLoadingLayoutProxy().setLastUpdatedLabel(null); 
      mRefreshListView.onRefreshComplete(); 
      isRefreshing = false;
