Android - status bar prevents full screen

问题

My app correctly runs in full screen when it's started. However after minimizing and then returning to the app, the status bar pops up and pushes my views down a little. How can I keep the status bar from moving my views?

Here is my layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:myapp="http://schemas.android.com/apk/res/com.example.draw"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
    <com.example.draw.DrawView 
        android:id="@+id/draw"
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        android:visibility="visible"
        android:fitsSystemWindows="false"
    />      
<com.admob.android.ads.AdView     
       android:id="@+id/ad" 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content"
       myapp:backgroundColor="#000000"
       myapp:primaryTextColor="#FFFFFF"
       myapp:secondaryTextColor="#CCCCCC"
       android:layout_gravity="bottom"
/>

Here is part of my activity's onCreate:

requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
    WindowManager.LayoutParams.FLAG_FULLSCREEN);

I also have the fullscreen theme in the manifest:

android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"

Thanks

There are known bugs with the status bar / notification bar.

See:

You can fix this issue with:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

(do that in onCreate).... note that this will break the soft keyboard (IME) - as edittext can no longer slide into view above the keyboard. That flag prevents the window from moving at all....

If you need an edit text to also work while fixing the status bug you can do

someEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {
                getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
            } else {
                hideKeyboard();
                getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
            }   
        }
    });
