实现方式
- 先在对应item项目组件的
xml中把想要添加的组件隐藏:
<?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="wrap_content"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="horizontal">
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/record_detail_interview_content_cb"
android:layout_gravity="center_vertical"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/record_detail_interview_content_tv"
android:layout_gravity="right|center_vertical"
tools:text="健康飲食"/>
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginRight="5dp"
android:layout_marginLeft="5dp"
<!-- 想要隐藏的组件, 设为invisible -->
android:visibility="invisible"
android:id="@+id/record_detail_interview_content_other_et"
android:layout_gravity="center|right"
android:gravity="center_horizontal"/>
</LinearLayout>
- 在
adapter中添加一个判断, 到了想要添加组件的那个item就把那个组件设为visible:
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) {
if(holder instanceof MultiViewHolder){
final MultiViewHolder viewHolder = (MultiViewHolder) holder;
viewHolder.mTvName.setText(datas.get(position));
viewHolder.mCheckBox.setChecked(isSelected.get(position));
// 如果为那个组件, 则把EditText设为可视
if (position == 8) {
EditText mEditText = holder.itemView.findViewById(R.id.record_detail_interview_content_other_et);
mEditText.setVisibility(View.VISIBLE);
mEditText.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
}
viewHolder.itemView.setSelected(isSelected.get(position));
viewHolder.itemView.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
isSelected.put(position, isSelected.get(position) ? false : true);
notifyItemChanged(position);
}
});
}
}
