Android 去除状态栏和隐藏虚拟按键

//取消状态栏
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
        WindowManager.LayoutParams.FLAG_FULLSCREEN);

一定得在setContentView()上面

隐藏虚拟按键：

protected void hideBottomUIMenu() {
    //隐藏虚拟按键，并且全屏
    if (Build.VERSION.SDK_INT > 11 && Build.VERSION.SDK_INT < 19) { // lower api
        View v = this.getWindow().getDecorView();
        v.setSystemUiVisibility(View.GONE);
    } else if (Build.VERSION.SDK_INT >= 19) {
        //for new api versions.
        View decorView = getWindow().getDecorView();
        int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY | View.SYSTEM_UI_FLAG_FULLSCREEN;
        decorView.setSystemUiVisibility(uiOptions);
    }
}

这个也可以：

public void hideNavigationBar() {
        int uiFlags = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
                | View.SYSTEM_UI_FLAG_FULLSCREEN; // hide status bar

        if (android.os.Build.VERSION.SDK_INT >= 19) {
            uiFlags |= View.SYSTEM_UI_FLAG_IMMERSIVE;//0x00001000; // SYSTEM_UI_FLAG_IMMERSIVE_STICKY: hide
        } else {
            uiFlags |= View.SYSTEM_UI_FLAG_LOW_PROFILE;
        }

        try {
            getWindow().getDecorView().setSystemUiVisibility(uiFlags);
        } catch (Exception e) {
            // TODO: handle exception
        }

}
