A Secondary Linkage ListView with refreshing and loading more.
Gradle
compile 'me.zhouzhuo.zzsecondarylinkage:zz-secondary-linkage:1.0.0'
Maven
<dependency>
<groupId>me.zhouzhuo.zzsecondarylinkage</groupId>
<artifactId>zz-secondary-linkage</artifactId>
<version>1.0.0</version>
<type>pom</type>
</dependency>
What does it look like ?
How to use it ?
准备工作
①第一步，添加布局
<me.zhouzhuo.zzsecondarylinkage.ZzSecondaryLinkage
android:id="@+id/zz_linkage"
android:layout_width="match_parent"
android:layout_height="match_parent"/>②定义没有数据时，显示的布局(可选)
例如：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="50dp"
android:gravity="center"
android:text="当前没有数据哟！" />
</LinearLayout>③给左侧菜单的Java Bean继承BaseMenuBean
//for left listView, java bean must extends BaseMenuBean
public static class LeftMenuEntity extends BaseMenuBean {}④分别给左右两别的ListView添加ViewHolder, 且继承BaseListViewHolder。
public class LeftListViewHolder extends BaseListViewHolder {
public TextView tvMacName;
public TextView tvMacId;
}public class RightListViewHolder extends BaseListViewHolder {
public ImageView ivPic;
public TextView tvProductName;
public TextView tvMacName;
public TextView tvTaskNum;
public TextView tvStartTime;
public TextView tvTaskId;
}⑤定义左右两个ListView的Adapter，必须继承LeftMenuBaseListAdapter<T extends BaseListViewHolder, K extends BaseMenuBean>
public class LeftMenuListAdapter extends LeftMenuBaseListAdapter<LeftListViewHolder, TaskListEntity.LeftMenuEntity> {
public LeftMenuListAdapter(Context ctx, List<TaskListEntity.LeftMenuEntity> list) {
super(ctx, list);
}
@Override
public LeftListViewHolder getViewHolder() {
return new LeftListViewHolder();
}
@Override
public void bindView(LeftListViewHolder leftListViewHolder, View itemView) {
ViewUtil.scaleContentView((ViewGroup) itemView.findViewById(R.id.root));
leftListViewHolder.tvMacName = (TextView) itemView.findViewById(R.id.tv_menu);
leftListViewHolder.tvMacId = (TextView) itemView.findViewById(R.id.tv_id);
}
@Override
public void bindData(LeftListViewHolder leftListViewHolder, int position) {
leftListViewHolder.tvMacName.setText(list.get(position).getMacName());
leftListViewHolder.tvMacId.setText(list.get(position).getMacId());
}
@Override
public int getLayoutId() {
return R.layout.list_item_menu;
}
//9-patch drawable
@Override
public int getIndicatorResId() {
return R.drawable.list_select;
}
}public class RightContentListAdapter extends RightMenuBaseListAdapter<RightListViewHolder, TaskListEntity.LeftMenuEntity.TaskListDataEntity> {
public RightContentListAdapter(Context ctx, List<TaskListEntity.LeftMenuEntity.TaskListDataEntity> list) {
super(ctx, list);
}
@Override
public RightListViewHolder getViewHolder() {
return new RightListViewHolder();
}
@Override
public void bindView(RightListViewHolder rightListViewHolder, View itemView) {
ViewUtil.scaleContentView((ViewGroup) itemView.findViewById(R.id.root));
rightListViewHolder.ivPic = (ImageView) itemView.findViewById(R.id.iv_pic);
rightListViewHolder.tvProductName = (TextView) itemView.findViewById(R.id.tv_product_name);
rightListViewHolder.tvMacName = (TextView) itemView.findViewById(R.id.mac_name);
rightListViewHolder.tvTaskNum = (TextView) itemView.findViewById(R.id.tv_task_number);
rightListViewHolder.tvTaskId = (TextView) itemView.findViewById(R.id.tv_task_id);
rightListViewHolder.tvStartTime = (TextView) itemView.findViewById(R.id.tv_start_time);
}
@Override
public void bindData(RightListViewHolder rightListViewHolder, int position) {
Glide.with(context).load(Constants.BASE_URL + getItem(position).getPicUrl()).into(rightListViewHolder.ivPic);
rightListViewHolder.tvProductName.setText(getItem(position).getProductName());
rightListViewHolder.tvMacName.setText(getItem(position).getMachineName());
rightListViewHolder.tvTaskNum.setText(getItem(position).getTaskNo());
rightListViewHolder.tvTaskId.setText(getItem(position).getTaskId());
rightListViewHolder.tvStartTime.setText(getItem(position).getStartTime());
}
@Override
public int getLayoutId() {
return R.layout.list_item_content;
}
}开始使用
⑥最后
//定义全局变量
private List<TaskListEntity.LeftMenuEntity> entities;
private ZzSecondaryLinkage zzSecondaryLinkage;
//findView
zzSecondaryLinkage = (ZzSecondaryLinkage) findViewById(R.id.zz_linkage);
//初始化左边ListView的Adapter
entities = new ArrayList<>();
LeftMenuListAdapter leftAdapter = new LeftMenuListAdapter(this, entities);
zzSecondaryLinkage.setLeftMenuAdapter(leftAdapter);
//初始化右边ListView的Adapter
List<TaskListEntity.LeftMenuEntity.TaskListDataEntity> rightEntity = new ArrayList<>();
final RightContentListAdapter rightAdapter = new RightContentListAdapter(this, rightEntity);
zzSecondaryLinkage.setRightContentAdapter(rightAdapter);
//设置左右两个ListView的点击监听
zzSecondaryLinkage.setOnItemClickListener(new ILinkage.OnItemClickListener() {
@Override
public void onLeftClick(View itemView, int position) {
Toast.makeText(MainActivity.this, "left," + position, Toast.LENGTH_SHORT).show();
rightAdapter.setList(entities.get(position).getTaskList());
}
@Override
public void onRightClick(View itemView, int position) {
Toast.makeText(MainActivity.this, "right," + position, Toast.LENGTH_SHORT).show();
}
});
//设置右边ListView的下拉刷新监听
zzSecondaryLinkage.setOnRefreshListener(new ILinkage.OnRefreshListener() {
@Override
public void onRefresh() {
new AsyncTask<Void, Void, Void>() {
@Override
protected Void doInBackground(Void... voids) {
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void aVoid) {
super.onPostExecute(aVoid);
zzSecondaryLinkage.stopRefresh();
}
}.execute();
}
});
//设置右边ListView的上拉加载监听
zzSecondaryLinkage.setOnLoadMoreListener(new ILinkage.OnLoadMoreListener() {
@Override
public void onLoad() {
new AsyncTask<Void, Void, Void>() {
@Override
protected Void doInBackground(Void... voids) {
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void aVoid) {
super.onPostExecute(aVoid);
zzSecondaryLinkage.stopLoadMore();
}
}.execute();
}
});
//从网络获取数据
Api.getInstance().mApiService.getTaskListData()
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.unsubscribeOn(Schedulers.io())
.subscribe(new Subscriber<TaskListEntity>() {
@Override
public void onCompleted() {
}
@Override
public void onError(Throwable e) {
LogUtils.e(e.getMessage());
}
@Override
public void onNext(TaskListEntity taskListEntity) {
//填充并刷新数据
entities = taskListEntity.getData();
zzSecondaryLinkage.updateData(entities);
}
});
