CymChad/BaserecyclerViewAdapterhelper framework
Introduction:
CymChad/BaserecyclerViewAdapterhelper is a functional enhancement framework for RecyclerView. It provides rich features to simplify the development of the RecyclerView adapter, which includes the method of event processing.In this article, we will introduce the event processing methods in CymChad/BaserecyclerViewAdapterhelper framework, and provide some Java code examples to illustrate its usage.
1. Overview of event handling
In RecyclerView, event processing is a very important part, such as clicking the event, long pressing the incident, etc.CymChad/BaserecyclerViewAdapterhelper framework provides a simple way to handle these events, so that developers can handle various events of RecyclerView more flexible and efficiently.
2. Click on the incident processing
CymChad/BaserecyclerViewAdapterhelper framework provides ItemClickListener and onItemlongClicklistener to handle the clicks and long -holding events.
1. Example of use of ItemClickListener
ItemClickListener is an interface that we can implement it in the RecyclerView adapter to handle the clicks.The following is an example code:
class MyAdapter extends BaseQuickAdapter<String, BaseViewHolder>{
public MyAdapter(List<String> data) {
super(R.layout.item_layout, data);
}
@Override
protected void convert(BaseViewHolder helper, String item) {
helper.setText(R.id.tvItem, item);
helper.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// Treat the logic of the click event
}
});
}
}
In the above examples, we set the listener for each item by rewriting the convert method of the adapter, so that the corresponding logic processing will be triggered when each item clicks.
2. OutemlongClickListener use examples
OntemlongClickListener is an interface. We can implement it in the RecyclerView adapter to handle long -holding incidents.The following is an example code:
class MyAdapter extends BaseQuickAdapter<String, BaseViewHolder>{
public MyAdapter(List<String> data) {
super(R.layout.item_layout, data);
}
@Override
protected void convert(BaseViewHolder helper, String item) {
helper.setText(R.id.tvItem, item);
helper.itemView.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View view) {
// Treat the logic of long pressing the incident
return true;
}
});
}
}
In the above example, through the Convert method of the adapter, we set the monitor of the long -pressing event for each item. When a certain item is pressed on time, the corresponding logical processing will be triggered, and the True indicates that it has been processed that it has been processed.This event.
3. Expansion of event handling
In addition to clicking the incident and long pressing the incident, CymChad/BaserecyclerViewAdapterhelper framework also provides a process of processing of various events. These events include the clicks of the child View in ITEM, the long press event of the child Views in Item.The following is an example code:
class MyAdapter extends BaseQuickAdapter<String, BaseViewHolder>{
public MyAdapter(List<String> data) {
super(R.layout.item_layout, data);
}
@Override
protected void convert(BaseViewHolder helper, String item) {
helper.setText(R.id.tvItem, item);
helper.getView(R.id.btnItem).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// The click event logic of the handling button
}
});
helper.getView(R.id.ivItem).setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View view) {
// Processing the long pressing event logic
return true;
}
});
}
}
In the above example, we obtain the sub -View in Item by calling BaseViewholder's getView method, and set the corresponding event monitor for the child View.This can handle various events of various seed views.
in conclusion:
CymChad/BaserecyClerViewAdapterhelper framework provides a simple way to handle various events of RecyclerView, including clicking events, long -holding events, and various events of ITEM neutron View.Developers can handle these events by implementing the corresponding interface or by monitoring.This can greatly improve the efficiency and flexibility of the RecyclerView adapter development.
