ステータスバーを非表示にするには

Question

ステータスバーが表示されなくなりました。私は私が説明してみましょう私は練習を実装しており、さらにedittext,のキーボードの場所のandroid:windowSoftInputMode="adjustResize"にマニフェストファイルを配置していますそれはうまくいきますが、私はnavigation barを隠したいので、"Theme.Holo.Light.NoActionBar.Fullscreen"テーマを使用しています。しかし、キーボードに表示されるアプリケーションのナビゲーションバーもスクロールします。キーボードが表示されているときにスクロールするナビゲーションバーと通知バーを非表示にするにはどうすればよいですか？

私は、これはあなたを助ける=>http://developer.android.com/reference/android/view/View.html#setSystemUiVisibility(int)

=> setSystemUiVisibility（newVis）だと思います。 //このメソッドはあなたを助けます

=>これは情報のクラスであり、理解を深めることです。

public static classコンテンツがScrollViewを継承します View.OnSystemUiVisibilityChangeListener、View.OnClickListener { TextView mText; TextView mTitleView; SeekBar mSeekView; ; boolean mNavVisible; int mBaseSystemUiVisibility = SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | SYSTEM_UI_FLAG_LAYOUT_STABLE; int mLastSystemUiVis;

Runnable mNavHider = new Runnable() { 
    @Override public void run() { 
     setNavVisibility(false); 
    } 
}; 

public Content(Context context, AttributeSet attrs) { 
    super(context, attrs); 

    mText = new TextView(context); 
    mText.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16); 
    mText.setText(context.getString(R.string.alert_dialog_two_buttons2ultra_msg)); 
    mText.setClickable(false); 
    mText.setOnClickListener(this); 
    mText.setTextIsSelectable(true); 
    addView(mText, new ViewGroup.LayoutParams(
      ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)); 

    setOnSystemUiVisibilityChangeListener(this); 
} 

public void init(TextView title, SeekBar seek) { 
    // This called by the containing activity to supply the surrounding 
    // state of the content browser that it will interact with. 
    mTitleView = title; 
    mSeekView = seek; 
    setNavVisibility(true); 
} 

@Override public void onSystemUiVisibilityChange(int visibility) { 
    // Detect when we go out of low-profile mode, to also go out 
    // of full screen. We only do this when the low profile mode 
    // is changing from its last state, and turning off. 
    int diff = mLastSystemUiVis^visibility; 
    mLastSystemUiVis = visibility; 
    if ((diff&SYSTEM_UI_FLAG_LOW_PROFILE) != 0 
      && (visibility&SYSTEM_UI_FLAG_LOW_PROFILE) == 0) { 
     setNavVisibility(true); 
    } 
} 

@Override protected void onWindowVisibilityChanged(int visibility) { 
    super.onWindowVisibilityChanged(visibility); 

    // When we become visible, we show our navigation elements briefly 
    // before hiding them. 
    setNavVisibility(true); 
    getHandler().postDelayed(mNavHider, 2000); 
} 

@Override protected void onScrollChanged(int l, int t, int oldl, int oldt) { 
    super.onScrollChanged(l, t, oldl, oldt); 

    // When the user scrolls, we hide navigation elements. 
    setNavVisibility(false); 
} 

@Override public void onClick(View v) { 
    // When the user clicks, we toggle the visibility of navigation elements. 
    int curVis = getSystemUiVisibility(); 
    setNavVisibility((curVis&SYSTEM_UI_FLAG_LOW_PROFILE) != 0); 
} 

void setBaseSystemUiVisibility(int visibility) { 
    mBaseSystemUiVisibility = visibility; 
} 

void setNavVisibility(boolean visible) { 
    int newVis = mBaseSystemUiVisibility; 
    if (!visible) { 
     newVis |= SYSTEM_UI_FLAG_LOW_PROFILE | SYSTEM_UI_FLAG_FULLSCREEN; 
    } 
    final boolean changed = newVis == getSystemUiVisibility(); 

    // Unschedule any pending event to hide navigation if we are 
    // changing the visibility, or making the UI visible. 
    if (changed || visible) { 
     Handler h = getHandler(); 
     if (h != null) { 
      h.removeCallbacks(mNavHider); 
     } 
    } 

    // Set the new desired visibility. 
    setSystemUiVisibility(newVis); 
    mTitleView.setVisibility(visible ? VISIBLE : INVISIBLE); 
    mSeekView.setVisibility(visible ? VISIBLE : INVISIBLE); 
}
