Android 表白墙表白墙前言：毕业设计没有需求，自己想需求，没什么太多想法，突然想起来有个渤大表白墙这个功能也不错，随便写一下。

具体就是一个弹窗插入数据，获取数据，在ListView中显示适配，下拉刷新。 public class ConfessionFragment extends BaseFragment implements SwipeRefreshLayout.OnRefreshListener { @BindView(R.id.msg_love_list) ListView msgListView; @BindView(R.id.refresh_love) SwipeRefreshLayout refreshLove; List mMsgLoveList = new ArrayList(); MsgLoveAdapter mMsgLoveAdapter; public static Fragment getInstance() { Fragment fragment = new ConfessionFragment(); return fragment; } @Override protected int contentViewID() { return R.layout.fragment_confession; } @Override protected void initialize() { EventBus.getDefault().register(this); refreshLove.setOnRefreshListener(this); refreshLove.setColorSchemeColors(getResources().getColor(R.color.color_love)); queryLoveMsg(); } private void queryLoveMsg() { BmobQuery msgLoveBmobQuery = new BmobQuery(); msgLoveBmobQuery.order("-createdAt"); msgLoveBmobQuery.findObjects(new FindListener() { @Override public void done(List object, BmobException e) { if (e == null) { mMsgLoveList = object; mMsgLoveAdapter = new MsgLoveAdapter(getContext(), R.layout.item_confession, mMsgLoveList); msgListView.setAdapter(mMsgLoveAdapter); } else { ToastUtils.showShort(getContext(), getContext().getString(R.string.query_failure)); } } }); } @Override public void onRefresh() { queryLoveMsg(); mMsgLoveAdapter.notifyDataSetChanged(); refreshLove.setRefreshing(false); } @Subscribe(threadMode = ThreadMode.MAIN) public void onEvent(MessageEvent messageEvent) { switch (messageEvent.getMessage()) { case ConstantConfig.UPDATE_LOVE: onRefresh(); break; default: } } @OnClick({R.id.btn_add_love}) public void onClick(View view) { switch (view.getId()){ case R.id.btn_add_love: DialogUtils.addLoveDialog(getContext()); break; default:

} } @Override public void onStop() { super.onStop(); EventBus.getDefault().unregister(this); } } public class MsgLoveAdapter extends ArrayAdapter { public static final String TAG = "MsgLoveAdapter"; List mMsgLoveList; private int resourceId; public MsgLoveAdapter(@NonNull Context context, int resource, @NonNull List objects) { super(context, resource, objects); resourceId = resource; } @NonNull @Override public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) { MsgLove msgLove = getItem(position); ViewHolder viewHolder; View view; if (convertView == null) { view = LayoutInflater.from(getContext()).inflate(resourceId, null); viewHolder = new ViewHolder(); viewHolder.loveTo = view.findViewById(R.id.love_to); viewHolder.loveFrom = view.findViewById(R.id.love_from); viewHolder.loveContent = view.findViewById(R.id.love_content); view.setTag(viewHolder); } else { view = convertView; viewHolder = (ViewHolder) view.getTag(); } viewHolder.loveTo.setText(msgLove.getTo()); viewHolder.loveContent.setText(msgLove.getContent()); viewHolder.loveFrom.setText(msgLove.getFrom()); return view; } class ViewHolder { TextView loveTo; TextView loveFrom; TextView loveContent; SimpleDraweeView loveImg; } } public class DialogUtils { public static void addLoveDialog(Context context) { View view = LayoutInflater.from(context).inflate(R.layout.add_love_tip, null); EditText etLoveTo = view.findViewById(R.id.et_love_to); EditText etLoveFrom = view.findViewById(R.id.et_love_from); EditText etLoveSays = view.findViewById(R.id.et_love_says); Button btnLovePublish = view.findViewById(R.id.btn_love_publish); Button btnLoveCancel = view.findViewById(R.id.btn_love_cancel); final Dialog dialog = new AlertDialog.Builder(context) .setView(view) .setCancelable(true) .create(); btnLovePublish.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { if (TextUtils.isEmpty(etLoveTo.getText().toString()) || TextUtils.isEmpty(etLoveFrom.getText().toString()) || TextUtils.isEmpty(etLoveSays.getText().toString())){ ToastUtils.showShort(context,context.getString(R.string.tip_empty)); return; }

MsgLove msgLove = new MsgLove(); MyUser myUser = MyUser.getCurrentUser(MyUser.class); msgLove.setUsername(myUser.getUsername()); msgLove.setTo(etLoveTo.getText().toString()); msgLove.setFrom(etLoveFrom.getText().toString()); msgLove.setContent(etLoveSays.getText().toString()); msgLove.save(new SaveListener() { @Override public void done(String s, BmobException e) { if (e == null) { ToastUtils.showShort(context,context.getString(R.string.love_send)); EventBus.getDefault().post(new MessageEvent(ConstantConfig.UPDATE_LOVE)); dialog.dismiss(); } else { ToastUtils.showShort(context,context.getString(R.string.love_fail)); } } }); } }); btnLoveCancel.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { dialog.dismiss(); } }); dialog.show(); } } 作者：江南233
