Android:如何让键盘输入按钮说"搜索"并处理其点击？

<EditText
    android:id="@+id/editText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:imeOptions="actionSearch"
    android:inputType="text"
    android:hint="输入搜索内容" />

<Button
    android:id="@+id/searchButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="搜索" />

EditText editText = findViewById(R.id.editText);
Button searchButton = findViewById(R.id.searchButton);

editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_SEARCH) {
            performSearch();
            return true;
        }
        return false;
    }
});

searchButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        performSearch();
    }
});

private void performSearch() {
    String searchText = editText.getText().toString();
    // 执行搜索操作
    // ...
}
