Android 4.4沉浸式状态栏的实现

要实现Android 4.4上面的沉浸式状态栏要用到开源项目SystemBarTint（https://github.com/hexiaochun/SystemBarTint）

public class MainActivity extends Activity {  

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);  

       if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            setTranslucentStatus(true);
        }

        SystemBarTintManager tintManager = new SystemBarTintManager(this);
        tintManager.setStatusBarTintEnabled(true);
        tintManager.setStatusBarTintResource(R.drawable.back);

    }

    @TargetApi(19)
    public void setTranslucentStatus(boolean on) {
        Window win = getWindow();
        WindowManager.LayoutParams winParams = win.getAttributes();
        final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
        if (on) {
            winParams.flags |= bits;
        } else {
            winParams.flags &= ~bits;
        }
        win.setAttributes(winParams);
    }

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"  

    android:fitsSystemWindows="true"
    android:clipToPadding="true"  

    android:background="#ffffff"
    android:orientation="vertical"
>  

    <TextView
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:background="#009959" />  

    <Button
        android:layout_width="100dp"
        android:layout_height="50dp"
        android:background="#ff669d"/>  

</LinearLayout>  

android:fitsSystemWindows="true"  ：设置应用布局时是否考虑系统窗口布局；如果为true，将调整系统窗口布局以适应你自定义的布局。比如系统有状态栏，应用也有状态栏时。

android:clipToPadding="true"  ： 属性定义了是否允许ViewGroup在padding中绘制,该值默认为true,即不允许。

效果如下：
