如何从左到右更改SearchView图标的位置 [英] How to change the SearchView icon position from left to right

问题描述

我具有以下包含SearchView的布局，并且我希望其图标位于右侧而不是默认的左侧.我在此处查找了多个帖子及其各自的答案，但没有一个起作用.关于如何做的任何想法?我可以添加xml属性吗，还是必须以编程方式进行设置?

I have the following layout which contains a SearchView and i want its icon to be on the right side instead of the default left. I looked up multiple posts on here and their respective answers but none worked. Any ideas on how to do it? Is there an xml attribute i can add or do i have to do it programatically?

menu.xml:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto">

        <item
            android:id="@+id/search"
            android:icon="@drawable/ic_search_white"
            android:title="@string/search"
            app:actionViewClass="androidx.appcompat.widget.SearchView"
            app:showAsAction="always|collapseActionView" />
</menu

YourActivity.java

public class MainActivity extends AppCompatActivity implements SearchView.OnQueryTextListener {

    Toolbar toolbar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_search);  
        toolbar=findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
    }
            @Override
             public boolean onCreateOptionsMenu(Menu menu) {
                    getMenuInflater().inflate(R.menu.home_menu, menu);
                    MenuItem searchItem = menu.findItem(R.id.search);
                    SearchView searchView = (SearchView) searchItem.getActionView();
                    searchView.setOnQueryTextListener(this);
                    return super.onCreateOptionsMenu(menu);
              }

        //Override below methods:

            @Override
            public boolean onQueryTextSubmit(String query) {
                return false;
            }

            @Override
            public boolean onQueryTextChange(String newText) {
                return false;
