第一个页面(没问题)
@BindView(R.id.title_tv)
TextView titleTv;
@BindView(R.id.recycler)
RecyclerView recyclerView;
@BindView(R.id.refresh)
SwipeRefreshLayout refreshLayout;
@BindView(R.id.no_details)
LinearLayout noDetails;
List<WalletDetailsBean.ResultBean.ListBean> transactionList = new ArrayList<WalletDetailsBean.ResultBean.ListBean>();
private TransactionListAdapter adapter;
private String token;
private int page = 1;
....
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_wallet_details);
ButterKnife.bind(this);
Intent intent = getIntent();
if(intent != null){
token = intent.getStringExtra("token") != null ? intent.getStringExtra("token") : " ";
}
initTitle();
initView();
initData(token);
}
....
private void initView() {
refreshLayout.setOnRefreshListener(this);
refreshLayout.setColorSchemeResources(android.R.color.holo_blue_bright,
android.R.color.holo_green_light,
android.R.color.holo_orange_light,
android.R.color.holo_red_light);
refreshLayout.setProgressBackgroundColor(R.color.refresh_bg);
initListView();
}
private void initListView() {
layoutManager = new LinearLayoutManager(this);
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(layoutManager);
adapter = new TransactionListAdapter(this, transactionList);
recyclerView.setAdapter(adapter);
recyclerView.setBackgroundColor(Color.WHITE);
// 第一次进入页面的时候显示加载进度条
refreshLayout.setProgressViewOffset(true, 0,
(int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 24,
getResources().getDisplayMetrics()));
refreshLayout.setRefreshing(true);
//滚动监听
recyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
if (newState == RecyclerView.SCROLL_STATE_IDLE && lastVisibleItem + 1 == adapter.getItemCount()) {
refreshLayout.setRefreshing(true);
page++;
if (page <= totalPage) { //根据后台接口 判断当前页是否小于总页
L.e("pageNo:" + page + ",totalPage:" + totalPage);
queryTransactionDetails(MywalletDetailActivity.this,token,page);
showToast(getResources().getString(R.string.loading));
} else {
refreshLayout.setRefreshing(false);
showToast(getString(R.string.no_more_data));
}
}
}
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
lastVisibleItem = layoutManager.findLastVisibleItemPosition();
}
});
}
两个页面的xml文件都差不多：
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
...
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/refresh"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler"
android:paddingTop="@dimen/common_10"
android:background="#eaeaea"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</android.support.v4.widget.SwipeRefreshLayout>
</LinearLayout>
第二个页面：
@BindView(R.id.title_tv)
TextView titleTv;
@BindView(R.id.no_schedule_ll)
LinearLayout noScheduleLl;
@BindView(R.id.recycler)
RecyclerView recyclerView;
@BindView(R.id.refresh_myschedule)
SwipeRefreshLayout refreshLayout;
...
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_schedule);
ButterKnife.bind(this);
withRefreshView = setRefreshView();
intent = getIntent();
userid = intent.getStringExtra("userid");
token = intent.getStringExtra("token");
initView();
loadFromNet(token,pageNo);
}
/**
* 初始化控件
*/
private void initView() {
titleTv.setText(getResources().getString(R.string.my_schedule));
needHelp.setVisibility(View.VISIBLE);
needHelp.setText(getResources().getString(R.string.need_help));
refreshLayout.setOnRefreshListener(this);
refreshLayout.setColorSchemeResources(android.R.color.holo_blue_bright,
android.R.color.holo_green_light,
android.R.color.holo_orange_light,
android.R.color.holo_red_light);
refreshLayout.setProgressBackgroundColor(R.color.refresh_bg);
refreshLayout.setRefreshing(true);
/*
* 第一次进入页面的时候显示加载进度条
*/
refreshLayout.setProgressViewOffset(true, 0,
(int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 24,
getResources().getDisplayMetrics()));
refreshLayout.setRefreshing(true);
initListView();
}
private void initListView() {
recyclerView.setItemAnimator(new DefaultItemAnimator());//设置item动画
recyclerView.setHasFixedSize(true); //如果可以确定每个item的高度是固定的，设置这个选项可以提高性能
//创建默认的线性LayoutManage
layoutManager = new LinearLayoutManager(this);
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setBackgroundColor(Color.WHITE);
recyclerView.addItemDecoration(new MyDecoration(this, MyDecoration.VERTICAL_LIST));//自定义的分隔线
adapter = new ScheduleAdapter(this, scheduleList);
adapter.setOnItemClickListener(new ScheduleAdapter.OnItemClickListener() {
@Override
public void onItemClick(View view, int position) {
startActivity(new Intent(MyScheduleActivity.this, ShowWebViewActivity.class)
.putExtra("title",getResources().getString(R.string.riding_details_title))
.putExtra("share",getResources().getString(R.string.riding_details_share))
.putExtra("url", Url.getMyScheduleDetailUrl(true) + "?token=" + token +"&id=" + rideId));
}
});
adapter.setOnItemLongClickListener(new ScheduleAdapter.OnItemLongClickListener() {
@Override
public void onItemLongClick(View view, int position) {
}
});
recyclerView.setAdapter(adapter);
recyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
if (newState == RecyclerView.SCROLL_STATE_IDLE && lastVisibleItem + 1 == adapter.getItemCount()) {
refreshLayout.setRefreshing(true);
pageNo++;
if (pageNo <= totalPage) { //根据后台接口 判断当前页是否小于总页
L.e("pageNo:" + pageNo + "newsTotalPage:" + totalPage);
loadFromNet(token, pageNo);
showToast(getResources().getString(R.string.loading));
} else {
refreshLayout.setRefreshing(false);
showToast(getString(R.string.no_more_data));
}
}
}
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
lastVisibleItem = layoutManager.findLastVisibleItemPosition();
}
});
}
跳转到第一个页面正常显示列表，跳转到第二个页面的时候报错
请问是怎么回事，看了一天了还是看不出所以然来。
谢谢~
