使用Edittext实现搜索视图的功能

<EditText
    android:id="@+id/searchEditText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="输入搜索关键字"
    android:imeOptions="actionSearch"
    android:inputType="text"
    android:singleLine="true" />

EditText searchEditText = findViewById(R.id.searchEditText);

searchEditText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView textView, int actionId, KeyEvent keyEvent) {
        if (actionId == EditorInfo.IME_ACTION_SEARCH || keyEvent.getKeyCode() == KeyEvent.KEYCODE_ENTER) {
            String keyword = searchEditText.getText().toString();
            performSearch(keyword);
            return true;
        }
        return false;
    }
});

private void performSearch(String keyword) {
    // 在这里实现搜索逻辑，可以调用相关的搜索接口或处理搜索结果
    // ...
}
