更改默认搜索视图android的图标

Question

我遇到了默认搜索视图图标的问题。我想更改应用程序中的图标并使用自定义drawable而不是默认值。

我正在使用xml：

 <SearchView
                    android:id="@+id/searchView1"
                    android:layout_width="wrap_content"
                    android:layout_height="35dp"
                    android:layout_marginBottom="10dp"
                    android:layout_marginTop="10dp" >
                </SearchView>

感谢您的帮助。

这里我给的是whatsApp中使用的searchView代码，如

您的activity_main.xml布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:orientation="vertical">
    <TextView
           android:id="@+id/status_text"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           android:gravity="center_horizontal"/>
</LinearLayout>

菜单文件夹中的searchview_in_menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

<item android:id="@+id/action_search"

         android:title="Search"
         android:icon="@android:drawable/ic_menu_search"
         android:showAsAction="always"
         android:actionLayout="@layout/searchview_layout"/>
</menu>

布局文件夹中的searchview_layout.xml

<?xml version="1.0" encoding="utf-8"?>
    <SearchView xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/search_view_layout"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"/>

您的MainActivity.java

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.Window;
import android.widget.SearchView;

public class MainActivity extends Activity {
    private SearchView mSearchView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
        setContentView(R.layout.activity_main);
    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.searchview_in_menu, menu);
        //find the search view item and inflate it in the menu layout
        MenuItem searchItem = menu.findItem(R.id.action_search);
        mSearchView = (SearchView) searchItem.getActionView();
        //set a hint on the search view (optional)
        mSearchView.setQueryHint(getString(R.string.search));
        //these flags together with the search view layout expand the search view in the landscape mode
        searchItem.setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW
                | MenuItem.SHOW_AS_ACTION_ALWAYS);
        //expand the search view when entering the activity(optional)
        searchItem.expandActionView();
        return true;
    }

它将产生如下截图的结果

希望它能满足你的目的。
