Android App 隱藏顯示標題欄、狀態欄、導航欄
1. 隱藏當前Activity標題欄
在當前Activity中調用:this.requestWindowFeature(Window.FEATURE_NO_TITLE);
2. 隱藏當前Activity狀態欄(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. 隱藏當前Activity界面的導航欄(NavigationBar),在定製項目實際中遇到過
在Android4.0及以後版本中,可通過以下方法隱藏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);
4. 隱藏所有Activity界面的標題欄
修改AndroidManifest.xml
在application 標籤中添加a
android:theme="@android:style/Theme.NoTitleBar"
5. 隱藏所有Activity界面的TitleBar 和StatusBar
修改AndroidManifest.xml
在application 標籤中添加
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
