前提使用此库继承里面的Adapter方式
CymChad/BaseRecyclerViewAdapterHelper
Add OnItemClickLister
Use it item click ( Currently ,we support two way to setting click event ,you can choose any one )
image
一 adapter.setOnItemClickListener(listener)
Use it item click
1. adapter.setOnItemClickListener(new BaseQuickAdapter.OnItemClickListener() {
@Override
public void onItemClick(BaseQuickAdapter adapter, View view, int position) {
Log.d(TAG, "onItemClick: ");
Toast.makeText(ItemClickActivity.this, "onItemClick" + position, Toast.LENGTH_SHORT).show();
}
});
Use it item long click
2. adapter.setOnItemLongClickListener(new BaseQuickAdapter.OnItemLongClickListener() {
@Override
public boolean onItemLongClick(BaseQuickAdapter adapter, View view, int position) {
Log.d(TAG, "onItemLongClick: ");
Toast.makeText(ItemClickActivity.this, "onItemLongClick" + position, Toast.LENGTH_SHORT).show();
return false;
}
});
Use it item child click
3.- first register child view id in adapter
@Override
protected void convert(BaseViewHolder viewHolder, Status item) {
viewHolder.setText(R.id.tweetName, item.getUserName())
.setText(R.id.tweetText, item.getText())
.setText(R.id.tweetDate, item.getCreatedAt())
.setVisible(R.id.tweetRT, item.isRetweet())
.addOnClickListener(R.id.tweetAvatar)
.addOnClickListener(R.id.tweetName)
.linkify(R.id.tweetText);
}
adapter.setOnItemChildClickListener(new BaseQuickAdapter.OnItemChildClickListener() {
@Override
public boolean onItemChildClick(BaseQuickAdapter adapter, View view, int position) {
Log.d(TAG, "onItemChildClick: ");
Toast.makeText(ItemClickActivity.this, "onItemChildClick" + position, Toast.LENGTH_SHORT).show();
return false;
}
});
Use it item child long click
- first register child view id in adapter
@Override
protected void convert(BaseViewHolder helper, Status item) {
helper.setText(R.id.tweetName, item.getUserName())
.setText(R.id.tweetText, item.getText())
.setText(R.id.tweetDate, item.getCreatedAt())
.setVisible(R.id.tweetRT, item.isRetweet())
.addOnLongClickListener(R.id.tweetText)
.linkify(R.id.tweetText);
}
adapter.setOnItemChildLongClickListener(new BaseQuickAdapter.OnItemChildLongClickListener() {
@Override
public void onItemChildLongClick(BaseQuickAdapter adapter, View view, int position) {
Log.d(TAG, "onItemChildLongClick: ");
Toast.makeText(ItemClickActivity.this, "onItemChildLongClick" + position, Toast.LENGTH_SHORT).show();
}
});
If you do not want to use the above method ,you can use other way, we alse support the recyclerView.addOnItemTouchListener( listener )
二 mRecyclerView.addOnItemTouchListener ( listener)
mRecyclerView.addOnItemTouchListener(new OnItemClickListener( ){
@Override
public void onSimpleItemClick(BaseQuickAdapter adapter, View view, int position) {
Toast.makeText(RecyclerClickItemActivity.this, "" + Integer.toString(position), Toast.LENGTH_SHORT).show();
}
});
Use it item long click
mRecyclerView.addOnItemTouchListener(new OnItemLongClickListener( ) {
@Override
public void onSimpleItemLongClick(BaseQuickAdapter adapter, View view, int position) {
Toast.makeText(RecyclerClickItemActivity.this, "" + Integer.toString(position), Toast.LENGTH_SHORT).show();
}
});
Use it item child click
- first you should register child view id in adapter
@Override
protected void convert(BaseViewHolder viewHolder, Status item) {
viewHolder.setText(R.id.tweetName, item.getUserName())
.setText(R.id.tweetText, item.getText())
.setText(R.id.tweetDate, item.getCreatedAt())
.setVisible(R.id.tweetRT, item.isRetweet())
.addOnClickListener(R.id.tweetAvatar)
.addOnClickListener(R.id.tweetName)
.linkify(R.id.tweetText);
}
- and then
mRecyclerView.addOnItemTouchListener(new OnItemChildClickListener( ) {
@Override
public void onSimpleItemChildClick(BaseQuickAdapter adapter, View view, int position) {
Toast.makeText(RecyclerClickItemActivity.this, "" + Integer.toString(position), Toast.LENGTH_SHORT).show();
}
});
Use it item child long click
- first register child view id in adapter
@Override
protected void convert(BaseViewHolder helper, Status item) {
helper.setText(R.id.tweetName, item.getUserName())
.setText(R.id.tweetText, item.getText())
.setText(R.id.tweetDate, item.getCreatedAt())
.setVisible(R.id.tweetRT, item.isRetweet())
.addOnLongClickListener(R.id.tweetText)
.linkify(R.id.tweetText);
}
- and then
mRecyclerView.addOnItemTouchListener(new OnItemChildLongClickListener( ) {
@Override
public void onSimpleItemChildLongClick(BaseQuickAdapter adapter, View view, int position) {
Toast.makeText(RecyclerClickItemActivity.this, "" + Integer.toString(position), Toast.LENGTH_SHORT).show();
}
});
if you wish to implement various forms of click
override differnet click
mRecyclerView.addOnItemTouchListener(new SimpleClickListener() {
@Override
public void onItemClick(BaseQuickAdapter adapter, View view, int position) {
Toast.makeText(RecyclerClickItemActivity.this, "" + Integer.toString(position), Toast.LENGTH_SHORT).show();
}
@Override
public void onItemLongClick(BaseQuickAdapter adapter, View view, int position) {
Toast.makeText(RecyclerClickItemActivity.this, "" + Integer.toString(position), Toast.LENGTH_SHORT).show();
}
@Override
public void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {
Toast.makeText(RecyclerClickItemActivity.this, "" + Integer.toString(position), Toast.LENGTH_SHORT).show();
}
@Override
public void onItemChildLongClick(BaseQuickAdapter adapter, View view, int position) {
Toast.makeText(RecyclerClickItemActivity.this, "" + Integer.toString(position), Toast.LENGTH_SHORT).show();
}
});
问题延伸1. LinearLayout 嵌套 RecyclerView 时，点击事件被RecyclerView抢占，导致外部LinearLayout拿不到事件，怎么实现LinearLayout的点击事件？如下已经解决方案
kotlin代码
recycleView?.setOnTouchListener { v, event ->
if (event?.action == MotionEvent.ACTION_UP) {
viewLinearLayout.performClick()
}
false
}
java代码：
