如何在android中制作搜索栏？

在布局文件中添加EditText和ImageButton组件，分别表示搜索框和搜索按钮。然后在Activity中定义它们，并设置OnClickListener处理搜索事件。接下来，使用SearchView和SearchManager来实现搜索功能。

参考代码如下：

布局文件：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <EditText
        android:id="@+id/search_edit_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Search"
        android:imeOptions="actionSearch"/>
    <ImageButton
        android:id="@+id/search_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@android:drawable/ic_search_category_default"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"/>
</RelativeLayout>
在Activity中定义并设置OnClickListener：
public class SearchActivity extends AppCompatActivity {
    private EditText searchEditText;
    private ImageButton searchButton;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_search);
        searchEditText = findViewById(R.id.search_edit_text);
        searchButton = findViewById(R.id.search_button);
        searchButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String query = searchEditText.getText().toString();
                //处理搜索事件
使用SearchView和SearchManager实现搜索功能：
public class SearchActivity extends AppCompatActivity {
    private EditText searchEditText;
    private ImageButton searchButton;
    private SearchView searchView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_search);
        searchEditText = findViewById(R.id.search_edit_text);
        searchButton = findViewById(R.id.search_button);
        searchButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String query = searchEditText.getText().toString();
                //处理搜索事件
        searchView = findViewById(R.id.search_view);
        SearchManager searchManager = (
