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<ListView>, PostListener {   private InteractionAdapter mAdapter;   private PullToRefreshListView mRefreshListView;   private View mFooter;   private Context mContext;   private Button btnToPost;   protected int mPage = 0;   private boolean isRefreshing = false;   @Override   protected void onCreate(Bundle savedInstanceState) {     // TODO Auto-generated method stub     super.onCreate(savedInstanceState);     setContentView(R.layout.friends_list);     mContext=getApplicationContext();     mAdapter = new InteractionAdapter(mContext);     mAdapter.setListener(this);     btnToPost=(Button) findViewById(R.id.btn_topost);     mRefreshListView = (PullToRefreshListView) findViewById(R.id.friends_list);     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();       }     });   }      protected void myPosts() {     new AlertDialog.Builder(this).setItems(new String[]{"图片","视频","文字"}, new DialogInterface.OnClickListener() {              @Override       public void onClick(DialogInterface dialog, int which) {         Intent intent=new Intent();         switch (which) {         case 0:           intent.setClass(FriendsListActivity.this, CreatePostActivity.class);           break;         case 1:           intent.setClass(FriendsListActivity.this, RecorderActivity.class);           break;         case 2:           intent.setClass(FriendsListActivity.this, RecorderActivity.class);           break;         default:           break;         }         startActivity(intent);       }     }).show();        }   /**    * 查看更多操作    */   @Override   public void show(Interaction interaction) {        }      @Override   public void delete(Interaction interaction) {     // TODO Auto-generated method stub        }    @Override   public void onRefresh(PullToRefreshBase<ListView> refreshView) {     if (!isRefreshing) {        isRefreshing = true;        mPage = 0;       FriendsApi.getFriendsList(mContext, mCallBack);     }    }    protected NetCallBack mCallBack = new NetCallBack() {          public void friendslist(ArrayList<Interaction> friends) {       Log.i("friends size>>>>",friends.size()+"-------------");       mAdapter.setInteractions(friends); //     mRefreshListView.getLoadingLayoutProxy().setLastUpdatedLabel(null);       mRefreshListView.onRefreshComplete();       isRefreshing = false;       dismissLoading();     };          public void start() {       showLoading();     };          public void failed(String message) {       loadFailed();     };   };   @Override   public void play(Interaction interaction) {     Intent mIntent=new Intent();     mIntent.setClass(FriendsListActivity.this, RecorderPlayActivity.class);     Bundle data = new Bundle();     data.putString("path", interaction.videoPath);     mIntent.putExtras(data);     startActivity(mIntent);   } }
