全屏

当一个A activity跳转到另一个B activiy的时候，B activiy展开不是全屏，虽然xml设置成了fill_parent.

方法1：目标使B activiy全屏(包括状态栏)

解决：

<activity
            android:name="com.xxx.xxxx.BActivity"
            android:screenOrientation="portrait"
            android:theme="@style/MyDialogStyle" >
              <intent-filter>
                <action android:name="com.xxx.xxxx.BActivity" />

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

<activity
            android:name="com.xxx.xxxx.BActivity"
            android:screenOrientation="portrait"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
              <intent-filter>
                <action android:name="com.xxx.xxxx.BActivity" />

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

方法2：目标使B activiy全屏(不包括状态栏)

<activity
           android:name="com.xxx.xxxx.BActivity"
            android:screenOrientation="portrait"
            android:theme="@android:style/Theme.NoTitleBar.OverlayActionModes">
              <intent-filter>
                <action android:name="com.xxx.xxxx.BActivity" />

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

Api版本最少11：

android:minSdkVersion="11"
