带有动作栏的Android light主题

Question

I want to use a light theme, but still have an actionbar visible.

From here it looks like this should work:

<activity android:theme="@style/Theme.AppCompat.Light" ... >

But when I add any android:theme the actionbar disappears.

I'm probably missing something obvious...

Edit: in case it helps

From the build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.company.app"
        minSdkVersion 15
        targetSdkVersion 21
        versionCode 5
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.0.0'
}

activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/screen_main"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    tools:context=".owg">

    <TextView android:id="@+id/textHeader"
        android:textSize="24sp"
        android:textColor="#006699"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:visibility="visible"
        />
    <ListView
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        />
    <TextView android:id="@android:id/empty"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Empty set"
        android:visibility="invisible"
        />

</LinearLayout>

main.java

package com.company.app;

import android.app.AlertDialog;
import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ListView;
import android.content.Intent;
import android.view.View;

public class Main extends ListActivity { 
    private String[] mBooks = new String[]{ "Informational", "Extensions" };
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        MySimpleArrayAdapter booksAdapter = new MySimpleArrayAdapter(this,mBooks);

        ListView lv = (ListView) findViewById(android.R.id.list);
        lv.setAdapter(booksAdapter);
    }

}

use this:

<activity android:theme="@style/Theme.AppCompat.Light.DarkActionBar" ... >

instead of :

<activity android:theme="@style/Theme.AppCompat.Light" ... >

It should work. The issue here, that you use style without actionBar now, and there is some choices how action bar will look(see related styles)

//Use this to fill your action bar with items
@Override public boolean onCreateOptionsMenu(Menu menu) { 
       MenuInflater inflater = getMenuInflater(); 
       inflater.inflate(R.menu.your_menu_name, menu); 
       return true;
} 

or if yout want custom view for your actionBar

//Getting action bar
mActionBar = getActionBar();

and then use

mActionBar.setCustomView(mCustomView);//View object for your actionBar
mActionBar.setDisplayShowCustomEnabled(true)

EDIT: if you can't see title bar you can create it programmatically

requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.settings);
activity.setTitle("Settings");
