在Android Kotlin中添加CardView和RecyclerView的搜索功能,可以按照以下步骤进行:
implementation 'androidx.cardview:cardview:1.0.0'
implementation 'androidx.recyclerview:recyclerview:1.0.0'
<LinearLayout
...>
<EditText
android:id="@+id/searchEditText"
... />
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/recyclerView"
... />
</LinearLayout>
val recyclerView: RecyclerView = findViewById(R.id.recyclerView)
val searchEditText: EditText = findViewById(R.id.searchEditText)
val layoutManager = LinearLayoutManager(this)
recyclerView.layoutManager = layoutManager
val adapter = YourAdapter(dataList) // dataList为原始数据列表
recyclerView.adapter = adapter
searchEditText.addTextChangedListener(object : TextWatcher {
override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {}
override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
adapter.filter.filter(s) // 根据搜索关键字过滤数据
}
override fun afterTextChanged(s: Editable?) {}
})
这样,当用户在搜索框中输入关键字时,适配器会根据关键字过滤数据,并更新RecyclerView的显示。
