2.1 Android 4.0 and Lower

[java] view
plain copy







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);

}

...

}

[java] view
plain copy







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

[java] view
plain copy







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);
