前言：话不多说，先看效果
步骤：
Step1，界面布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.example.administrator.parentproject.activity.MyCollectActivity">
<RelativeLayout
style="@style/TitleStyle_Relative">
<ImageView
android:id="@+id/back"
style="@style/TitleStyle_Back"
android:layout_alignParentBottom="true" />
<TextView
android:id="@+id/title_tv"
style="@style/TitleStyle_Text"
android:layout_centerHorizontal="true"
android:text="收藏" />
</RelativeLayout>
<LinearLayout
android:layout_marginTop="@dimen/dp_10"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RadioGroup
android:id="@+id/group"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="5dp"
android:orientation="horizontal" >
<RadioButton
android:id="@+id/btnCourse"
android:layout_width="100dp"
android:layout_height="30dp"
android:layout_weight="1"
android:background="@drawable/btn_shape_left"
android:button="@null"
android:checked="true"
android:gravity="center"
android:text="课程"
android:textColor="#000000" />
<RadioButton
android:id="@+id/btnDynamic"
android:layout_width="100dp"
android:layout_height="30dp"
android:layout_weight="1"
android:background="@drawable/btn_shape"
android:button="@null"
android:checked="true"
android:gravity="center"
android:text="动态"
android:textColor="#919191" />
</RadioGroup>
<android.support.v4.view.ViewPager
android:id="@+id/viewPager"
android:layout_marginTop="@dimen/dp_10"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>
Step2，定义碎片列表，初始化ViewPager
Coursefragment sFragment = new Coursefragment(); fragmentList = new ArrayList<Fragment>(); fragmentList.add(sFragment); DynamicFragment fFragment = new DynamicFragment(); fragmentList.add(fFragment); adapter = new MyFragmentPagerAdapter(getSupportFragmentManager(), fragmentList); viewPager.setAdapter(adapter); viewPager.setCurrentItem(0); viewPager.setOnPageChangeListener((ViewPager.OnPageChangeListener) new MyOnPageChangeListener());
Step3，定义MyOnPageChangeListener
private class MyOnPageChangeListener implements ViewPager.OnPageChangeListener{
@Override
public void onPageScrollStateChanged(int arg0) {
// TODO Auto-generated method stub
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
// TODO Auto-generated method stub
}
@Override
public void onPageSelected(int arg0) {
// TODO Auto-generated method stub
switch (arg0) {
case 0:
btnCourse.setTextColor(Color.parseColor("#000000"));
btnDynamic.setTextColor(Color.parseColor("#919191"));
break;
case 1:
btnCourse.setTextColor(Color.parseColor("#919191"));
btnDynamic.setTextColor(Color.parseColor("#000000"));
break;
}
}
}
Step4，GroupButton与ViewPager关联
group.setOnCheckedChangeListener((RadioGroup.OnCheckedChangeListener) new MyCheckChangeListener());
private class MyCheckChangeListener implements RadioGroup.OnCheckedChangeListener{
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
// TODO Auto-generated method stub
switch (checkedId) {
case R.id.btnCourse:
viewPager.setCurrentItem(0,false);
break;
case R.id.btnDynamic:
viewPager.setCurrentItem(1,false);
break;
}
}
}
Step5，碎片实现（两个碎片功能相近，这里只贴出课程收藏碎片的代码）
public class Coursefragment extends BaseFragment {
@BindView(R.id.ywjl_lv)
LRecyclerView ywjlLv;
private CourseAdapter mCollectAdapter;
private LRecyclerViewAdapter mLRecyclerViewAdapter;
private SharedPreferencesHelper shared;
private String token, userId;
private CommitParam commitParam;
private Call<ResponseBody> data;
private Map<String, String> map;
/**
* 服务器端一共多少条数据
*/
private static final int TOTAL_COUNTER = 1000;//如果服务器没有返回总数据或者总页数，这里设置为最大值比如10000，什么时候没有数据了根据接口返回判断
/**
* 每一页展示多少条数据
*/
private static final int REQUEST_COUNT = 10;
/**
* 已经获取到多少条数据了
*/
private static int mCurrentCounter = 0;
private boolean isLoadMore = false;
int page = 0;
private ArrayList<Course.ResultBean> mList;
private WeakHandler mHandler = new WeakHandler() {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
switch (msg.what) {
case 0:
case 1:
if (!isLoadMore) {
page = 0;
}
collectList(String.valueOf(page));
break;
case -3:
ywjlLv.refreshComplete(REQUEST_COUNT);
ywjlLv.setOnNetWorkErrorListener(new OnNetWorkErrorListener() {
@Override
public void reload() {
}
});
break;
default:
break;
}
}
};
@Override
protected boolean isLazyLoad() {
return false;
}
@Override
protected int getContentLayout() {
return R.layout.fragment_collect;
}
@Override
protected void initView() {
}
@Override
protected void initData() {
shared = new SharedPreferencesHelper(getActivity(), "user");
token = shared.getSharedPreference("token", "").toString();
userId = shared.getSharedPreference("userid", 0).toString();
mList = new ArrayList<Course.ResultBean>();
MyGridLayoutManager manager = new MyGridLayoutManager(MyApplication.getContextObject(), 2, LinearLayoutManager.VERTICAL, false);
ywjlLv.setLayoutManager(manager);
mCollectAdapter = new CourseAdapter(MyApplication.getContextObject(), R.layout.new_course_item, "sckc");
mLRecyclerViewAdapter = new LRecyclerViewAdapter(mCollectAdapter);
ywjlLv.setAdapter(mLRecyclerViewAdapter);
mHandler.sendEmptyMessage(1);
}
@Override
protected void setListener() {
ywjlLv.setOnRefreshListener(new OnRefreshListener() {
@Override
public void onRefresh() {
isLoadMore = false;
mHandler.sendEmptyMessage(1);
}
});
ywjlLv.setLoadMoreEnabled(false);
mLRecyclerViewAdapter.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(View view, int position) {
Intent intent = new Intent(MyApplication.getContextObject(), CoursePlayActivity.class);
intent.putExtra("csid", mList.get(position).getId());
intent.putExtra("title", mList.get(position).getCsName());
startActivity(intent);
}
});
}
private void collectList(String page) {
commitParam = new CommitParam();
commitParam.setToken(token);
map = commitParam.getData();
Call<ResponseBody> data = RetrofitBean.getApi2().getDataCourse("get_course_collects", map);
data.enqueue(new SimpleCallBack("课程收藏列表") {
@Override
protected void showData(int i, String json) {
super.showData(i, json);
Gson gson = new Gson();
Course yg = gson.fromJson(json, Course.class);
if (!isLoadMore) {
mList.clear();
mCollectAdapter.clear();
mCurrentCounter = 0;
}
mList.addAll(yg.getResult());
mCollectAdapter.addAll(yg.getResult());
ywjlLv.refreshComplete(REQUEST_COUNT);
}
@Override
protected void showData(String msg) {
if (!isLoadMore) {
mList.clear();
mCollectAdapter.setDataList(mList);
//禁用自动加载更多功能
mCurrentCounter = 0;
} else {
ywjlLv.setNoMore(true);
Toast.makeText(MyApplication.getContextObject(), "暂无更多数据", Toast.LENGTH_SHORT).show();
}
ywjlLv.refreshComplete(REQUEST_COUNT);
}
});
}
}
