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);
}
}
布局文件 friends_list.xml

适配器 InteractionAdapter 对朋友圈列表进行数据填充
public class InteractionAdapter extends BaseAdapter implements OnClickListener {
