如何设置edittext以显示搜索按钮或在键盘上输入按钮？

<EditText
    android:id="@+id/editText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="text" />

<EditText
    android:id="@+id/editText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="text"
    android:imeOptions="actionSearch" />

EditText editText = findViewById(R.id.editText);
editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView textView, int actionId, KeyEvent keyEvent) {
        if (actionId == EditorInfo.IME_ACTION_SEARCH) {
            // 执行搜索操作
            performSearch(textView.getText().toString());
            return true;
        }
        return false;
    }
});
