添加 ActionBar - 需要使用 Theme.AppCompat 主题

Question

我需要添加 ActionBar.I 从我的搜索中找到的步骤。

1.Added suppoprt 库（appcompat v7 支持库）

2.Extended 到 ActionBarActivity

3.Used styles.xml 和清单

中的 AppCompat 主题

但是运行该项目使设备崩溃并出现错误“您需要使用 Theme.AppCompat 主题”

styles.xml

<resources>

<style name="AppBaseTheme" parent="@style/Theme.AppCompat.Light">

</style>


<style name="RatingBar" parent="@android:style/Widget.RatingBar">
    <item name="android:progressDrawable">@drawable/ratingbar</item>
    <item name="android:minHeight">48dip</item>
    <item name="android:maxHeight">48dip</item>
</style>

</resources>

清单

<application
    android:icon="@drawable/poweritsolar"
    android:label="@string/app_name" 
    >
    <activity
        android:label="@string/app_name"
        android:name=".Powerit_solarActivity" 
        android:theme="@style/AppBaseTheme">
        <intent-filter >
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".login"></activity>
    <activity android:name=".signup"></activity>
    <activity android:name=".catagory_btns"></activity>
</application>

activity

public class catagory_btns extends ActionBarActivity{

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.catagory_btns);
    Button cat1=(Button)findViewById(R.id.cat1);


    cat1.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent in=new Intent(catagory_btns.this,login.class);
            startActivity(in);
        }
    });

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // TODO Auto-generated method stub
    getMenuInflater().inflate(R.menu.main, menu);
    ActionBar actionBar = getActionBar();
    actionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#00ffff")));
    return super.onCreateOptionsMenu(menu);
}

}

Answer 1

将 Java 继承从 ActionBarActivity 更改为 Activity，并保持 manifest 中的主题不变。

更多你可以查看这个http://developer.android.com/guide/topics/ui/actionbar.html

希望对您有所帮助:)！

Answer 2

替换

<style name="AppBaseTheme" parent="@style/Theme.AppCompat.Light">

和

<style name="AppBaseTheme" parent="android:Theme.AppCompat.Light">

检查你的值文件夹中没有几个 styles.xml，如果你支持很多 OS 版本，很可能是 IDE 生成了那些给你。
