我试图更新所有的库，但我仍然有错误。我能够在模拟器上运行应用程序，但是当我导出APK并在真实的Android设备上运行它时，该应用程序无法运行。Android SearchView不起作用

MinSdkVersion是8，targetSdkVersion是19. 请帮忙!!!

menu.xml文件

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

    <item 
     android:id="@+id/action_showTC" 
     android:orderInCategory="100" 
     android:showAsAction="never" 
     android:title="Terms and Conditions"/> 

    <item android:id="@+id/action_search" 
      android:title="Search" 
      android:orderInCategory="100" 
      example:showAsAction="ifRoom|collapseActionView" 
      example:actionViewClass="android.support.v7.widget.SearchView"/> 

</menu>

搜索查看

@Override 
public boolean onOptionsItemSelected(MenuItem item){ 
    if(item.getItemId() == R.id.action_showTC){ 
     startActivity(new Intent(MainActivity.this, T_C.class)); 
     return true; 
    }else{ 
     return super.onOptionsItemSelected(item); 
    } 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 

    MenuInflater inflater = getMenuInflater(); 
    inflater.inflate(R.menu.main, menu); 

    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE); 
    SupportMenuItem searchMenuItem = ((SupportMenuItem) menu.findItem(R.id.action_search)); 
    SearchView searchView = (SearchView) searchMenuItem.getActionView(); 
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName())); 

    return super.onCreateOptionsMenu(menu); 
}

对于API 11之前，你应该在兼容模式初始化操作栏项目：

@Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.main, menu); 
     SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE); 
     MenuItem searchMenuItem = menu.findItem(R.id.action_search); 
     SearchView searchView = (SearchView)MenuItemCompat.getActionView(searchMenuItem); 
     searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName())); 
     return true; 
    }

更新：
 所以，我试图在API中重现它8仿真器和4.4 KitKat。不幸的是，我的2.3.8设备刚刚变砖，所以无法检测低API的硬件。我可以建议你：
1.检查搜索查看从android.support.v7.widget.SearchView;
2.检查菜单资源进口是正确的：从onCreateOptionsMenu

<menu xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" <----------- init compatible namespace 
    xmlns:tools="http://schemas.android.com/tools" 
    tools:context=".MainActivity" > 

    <item 
     android:id="@+id/action_showTC" 
     android:orderInCategory="100" 
     android:title="@string/terms_and_conditions" 
     app:showAsAction="never"/> <----------- use compatible namespace 

    <item android:id="@+id/action_search" 
      android:title="@string/search" 
      android:orderInCategory="100" <---------- use different value 
      app:showAsAction="ifRoom|collapseActionView" 
      app:actionViewClass="android.support.v7.widget.SearchView"/> 

</menu>

3.返回true，如果没有底层处理（Activity类是不subclassed）

UPDATE2： GOT IT！您可能从Activity类延伸。应该ActioBarActivity：

public class MainActivity extends ActionBarActivity { 
...

是这样，但它仍然有相同的错误。 'MenuItem searchMenuItem = menu.findItem（R.id.action_search）; SearchManager searchManager =（SearchManager）getSystemService（Context.SEARCH_SERVICE）; SearchView searchView =（SearchView）MenuItemCompat.getActionView（searchMenuItem）; searchView.setSearchableInfo（searchManager.getSearchableInfo（getComponentName（）））;' – 2014-09-04 16:14:00

是否启用Proguard的在构建？如果是这样，您可能需要确保appcompat库位于Proguard排除列表中（在proguard.cfg中）。蛮力方法是保持所有支持库类有：

-keep class android.support.v4.app.** { *; } 
    -keep interface android.support.v4.app.** { *; } 
    -keep class android.support.v7.app.** { *; } 
    -keep interface android.support.v7.app.** { *; }

就我而言，我有这样的扩展支持库的搜索查看，所以我说这我ProGuard的一类。CFG：

-keep public class * extends android.support.v7.widget.SearchView { 
    public <init>(android.content.Context); 
    public <init>(android.content.Context, android.util.AttributeSet); 
}

的构造器是特别提到，以避免错误：

java.lang.NoSuchMethodException: <init> [class android.content.Context]

重现这个问题，这不适合我，但 - 维护类android.support.v7.widget.SearchView {*; }的确如此。 – Ernest 2016-04-04 15:36:25

SearchView是在android.support.v7.widget下不是android.support.v7.app包，所以最好使用-keep类android.support.v7。** {*; } – 2016-09-19 12:20:57

推出我的发布版本时，我（也）有

Attempt to invoke virtual method 'void android.support.v7.widget.SearchView.setOnQueryTextListener(android.support.v7.widget.ao)' on a null object reference

（使用ProGuard /缩小启用） 。

添加这ProGuard的规则固定它：

-keep class android.support.v7.widget.SearchView { *; }

这将保持搜索查看窗口小部件，但仍允许proguard的扔掉你没有使用任何其他支持库类，让你保持你的发布构建漂亮整齐。

太棒了！这对我来说是完美的 – ziniestro 2016-05-20 07:38:21

长时间的研究后，这个问题的一个简单的解决办法就是，只有在应用程序/ proguard的/ android.proguard文件添加

-keep class android.support.v7.widget.SearchView { *; }

的AndroidStudio。

干杯！

所需最低至proguard-rules.pro

-keep class android.support.v7.widget.SearchView { 
    public <init>(android.content.Context); 
    public <init>(android.content.Context, android.util.AttributeSet); 
}

这个解决方案今天仍然有用。从'com.android.tools.build：gradle：2.2.0'更新为'com.android.tools.build：gradle：2.2.2'时，再次弹出此bug弹出窗口，并且这个最小化的proguard规则修复了它。 – Carmen 2016-11-07 17:34:59

我不得不添加这和现在的作品顺利：

-keep class android.support.v7.widget.SearchView { 
    public <init>(android.content.Context); 
    public <init>(android.content.Context, android.util.AttributeSet); 
} 
-keep interface android.support.v7.widget.SearchView { 
    public <init>(android.content.Context); 
    public <init>(android.content.Context, android.util.AttributeSet); 
}
