基於android的朋友圈

編輯：關於Android編程

最近幾天寫了一個簡單的朋友圈程序，包含了朋友圈的列表實現，視頻的錄制、預覽與上傳，圖片可選擇拍照或者從相冊選取，從相冊選取可以一次選擇多張照片，並且限制照片的張數。大致也就這些功能了。

\
FriendsListActivity 代碼如下

 

public class FriendsListActivity extends BaseActivity implements OnRefreshListener, 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[]{"圖片","視頻","文字"}, new DialogInterface.OnClickListener() {
			
			@Override
			public void onClick(DialogInterface dialog, int which) {
				Intent intent=new Intent();

				startActivity(intent);
			}
		}).show();
		
	}
