SearchView（1）

步骤1 将SearchView作为OptionMenu的一个Item

res/menu/option_menu.xml

<?xml version="1.0" encoding="utf-8"?><menu xmlns:android="http://schemas.android.com/apk/res/android"      xmlns:app="http://schemas.android.com/apk/res-auto"      xmlns:tools="http://schemas.android.com/tools"      tools:context=".LauncherActivity">    <item        android:id="@+id/search_view"        android:title="搜索"        android:icon="@mipmap/search"        app:actionViewClass="android.support.v7.widget.SearchView"        app:showAsAction="ifRoom|collapseActionView"/></menu>

步骤2 设置SearchView的相关属性

MainActivity.java

package com.example.jun.searchviewtest;import android.os.Bundle;import android.support.v4.view.MenuItemCompat;import android.support.v7.app.AppCompatActivity;import android.support.v7.widget.SearchView;import android.view.Menu;import android.view.MenuItem;import android.widget.Toast;public class MainActivity extends AppCompatActivity {    private SearchView mSearchView;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        getMenuInflater().inflate(R.menu.option_menu, menu);        MenuItem item = menu.findItem(R.id.search_view);        //通过MenuItem的兼容版MenuItemCompat获取SearchView        mSearchView = (SearchView) MenuItemCompat.getActionView(item);        //监听搜索框        mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {            //提交搜索框内容，确定搜索            @Override            public boolean onQueryTextSubmit(String query) {                Toast.makeText(MainActivity.this, "确定搜索", Toast.LENGTH_SHORT).show();                return true;            }            //搜索框内容改变            @Override            public boolean onQueryTextChange(String newText) {                Toast.makeText(MainActivity.this, "搜索框内容改变了", Toast.LENGTH_SHORT).show();                return true;            }        });        return true;    }}
