1. 隐藏当前Activity标题栏

在当前Activity中调用：this.requestWindowFeature(Window.FEATURE_NO_TITLE);

2. 隐藏当前Activity状态栏(Status Bar)

2.1 Android 4.0 and Lower

public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        // If the Android version is lower than Jellybean, use this call to hide        // the status bar.        if (Build.VERSION.SDK_INT < 16) {            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,                    WindowManager.LayoutParams.FLAG_FULLSCREEN);        }        setContentView(R.layout.activity_main);    }    ...}

2.2 Android 4.1 and Higher

View decorView = getWindow().getDecorView();// Hide the status bar.int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;decorView.setSystemUiVisibility(uiOptions);// Remember that you should never show the action bar if the// status bar is hidden, so hide that too if necessary.ActionBar actionBar = getActionBar();actionBar.hide();

3. 隐藏当前Activity界面的导航栏(NavigationBar)

在Android4.0及以后版本中，可通过以下方法隐藏NavigationBar

View decorView = getWindow().getDecorView();// Hide both the navigation bar and the status bar.// SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as// a general rule, you should design your app to hide the status bar whenever you// hide the navigation bar.int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION              | View.SYSTEM_UI_FLAG_FULLSCREEN;decorView.setSystemUiVisibility(uiOptions);
