在 ActionBar 中显示 SearchView Android
Display SearchView in ActionBar Android
我正在尝试在 activity 的 ActionBar
中显示 SearchView
。我在此处遵循 android 开发人员指南 here
但是没有显示 SearchView
,我不明白为什么。
这是我的 activity
public class SearchActivity extends ActionBarActivity {
private String query;
@Override
protected void onCreate(Bundle savedInstanceState) {
FacebookSdk.sdkInitialize(getApplicationContext());
super.onCreate(savedInstanceState);
setContentView(R.layout.search_activity_layout);
Intent intent = getIntent();
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
this.query = intent.getStringExtra(SearchManager.QUERY);
Toast.makeText(this,query, Toast.LENGTH_LONG);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.options_menu, menu);
return true;
}
}
这里是 serachable.xml
文件
<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="@string/app_name"
android:hint="@string/search_hint" />
这里有 options_menu.xml
文件
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/search"
android:title="@string/search_title"
android:icon="@drawable/ic_action_search"
android:showAsAction="collapseActionView|ifRoom"
android:actionViewClass="android.widget.SearchView" />
</menu>
这是清单
<activity android:name=".SearchActivity"
android:label="SearchActivity">
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data android:name="android.app.searchable"
android:resource="@xml/searchable"/>
</activity>
唯一奇怪的是 options_menu.xml
文件中的这一行 (android:showAsAction="collapseActionView|ifRoom"
) 以红色突出显示。
尝试将其放入您的 options_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">
<item android:id="@+id/search"
android:title="@string/search_title"
android:icon="@drawable/ic_action_search"
app:actionViewClass="android.widget.SearchView"
app:showAsAction="collapseActionView|ifRoom" />
</menu>
这在你的 AndroidManifest.xml
<activity android:name=".SearchActivity"
android:label="SearchActivity">
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data android:name="android.app.searchable"
android:resource="@xml/searchable"/>
<meta-data android:name="android.app.default_searchable"
android:value=".SearchActivity" />
</activity>
这在你的 SearchActivity.java
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.options_menu, menu);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false);
return true;
}
@Override
protected void onNewIntent(Intent intent) {
setIntent(intent);
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
Log.e("query", intent.getStringExtra(SearchManager.QUERY));
}
}
供大家参考,希望对您有所帮助!
menu_main.xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/search"
android:title="@string/search_title"
android:icon="@drawable/ic_search"
android:showAsAction="collapseActionView|ifRoom"
android:actionViewClass="android.widget.SearchView" />
\res\xml\searchable.xml:
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="@string/app_name"
android:hint="@string/search_hint" />
AndroidManifest.xml:
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<meta-data android:name="android.app.searchable"
android:resource="@xml/searchable" />
</activity>
MainActivity.java:
package com.example.searchview;
import android.app.Activity;
import android.app.SearchManager;
import android.content.Context;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.SearchView;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
// Associate searchable configuration with the SearchView
SearchManager searchManager =
(SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView =
(SearchView) menu.findItem(R.id.search).getActionView();
searchView.setSearchableInfo(
searchManager.getSearchableInfo(getComponentName()));
return true;
}
...
}
试试下面的代码
menu_search.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" tools:context=".SearchActivity">
<item android:id="@+id/search"
android:title="Search"
android:icon="@android:drawable/ic_menu_search"
android:showAsAction="collapseActionView|ifRoom"
android:actionViewClass="android.widget.SearchView" />
</menu>
我认为你在上面的代码中犯了一个错误。
你在使用 appcompat 库吗?
如果没有,上面的代码应该可以工作。
如果是,请尝试使用 app:showAsAction
而不是 android:showAsAction
和
app:actionViewClass="android.support.v7.widget.SearchView"
而不是 android:actionViewClass="android.widget.SearchView"
