屏幕灯光调光器无法覆盖全屏android

Question

您好，我正在开发一个用于降低夜间屏幕亮度的应用程序。但是现在我面临一个问题，应用程序降低了屏幕亮度，但没有覆盖状态栏。任何想法怎么做

<style name="AppTheme" parent="@android:style/Theme.Translucent" />

<style name="Transparency" parent="AppTheme">
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@color/transparent</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>       
    <item name="android:backgroundDimEnabled">false</item>      
</style>

MainActivity.java

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);

    setContentView(R.layout.activity_main);
    initialize();                
}

private void initialize(){

    stopServiceIfActive();

    shared=new SharedMemory(this);
    alphaSeek=(SeekBar)findViewById(R.id.alphaControl);
    redSeek=(SeekBar)findViewById(R.id.redControl);
    greenSeek=(SeekBar)findViewById(R.id.greenControl);
    blueSeek=(SeekBar)findViewById(R.id.blueControl);

    alphaSeek.setOnSeekBarChangeListener(this);     
    redSeek.setOnSeekBarChangeListener(this);       
    greenSeek.setOnSeekBarChangeListener(this);
    blueSeek.setOnSeekBarChangeListener(this);

    alpha=shared.getAlpha();
    red=shared.getRed();
    green=shared.getGreen();
    blue=shared.getBlue();

    alphaSeek.setProgress(alpha);
    redSeek.setProgress(red);
    greenSeek.setProgress(green);
    blueSeek.setProgress(blue);

    updateColor();
}

任何想法
