我有一个不使用标题栏的应用程序,它在软糖设备中工作正常....但是当我在棉花糖设备中运行时,标题栏出现.... 这是我的清单文件

     <activity
        android:name=".PrintDialogActivity"
        android:theme="@style/AppTheme.NoActionBar"></activity>
    </application>

  </manifest>

我也试过添加这个

   this.requestWindowFeature(Window.FEATURE_NO_TITLE);

ActivityMain

public class MainActivity extends Activity
implements NavigationView.OnNavigationItemSelectedListener {
 ConnectionDetector cd;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Make this activity, full screen
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

    // Hide the Title bar of this activity screen
    getWindow().requestFeature(Window.FEATURE_NO_TITLE);

    setContentView(R.layout.activity_main);
  //Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);



    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
   // ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
 //           this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
 //   drawer.setDrawerListener(toggle);
//    toggle.syncState();

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);


   //main codes

 }

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK) {


        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(MainActivity.this);

        // set title
        alertDialogBuilder.setTitle("Exit");

        // set dialog message
        alertDialogBuilder
                .setMessage("Do you want to exit ?")
                .setCancelable(false)
                .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        // if this button is clicked, close
                        // The neutral button was clicked
                        Intent i = new Intent();
                        i.setAction(Intent.ACTION_MAIN);
                        i.addCategory(Intent.CATEGORY_HOME);
                        startActivity(i);
                        finish();
                    }
                })
                .setNegativeButton("No", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        // if this button is clicked, just close
                        // the dialog box and do nothing
                        dialog.cancel();
                    }
                });
        // create alert dialog
        AlertDialog alertDialog = alertDialogBuilder.create();

        // show it
        alertDialog.show();


        return true;
    }
    return super.onKeyDown(keyCode, event);



}

    } else if (id == R.id.nav_slideshow) {

    } else if (id == R.id.nav_manage) {

    }

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);

    return true;
   }
 }

android:theme="@style/AppTheme.NoActionBar you missed for Login Activity

更多导航抽屉需要操作栏。

  

那么如果你想要没有操作栏的导航抽屉,那就不好了   方式设计,用户永远不会知道有侧导航面板   它有一些选项,更多如何处理打开和关闭。通常在左上方会有一个图标来打开和关闭它。

将此行放在setContentView上方,并从Activity扩展您的类。

public class MainActivity extends Activity {

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

并且如果Yout想要从AppCompactActivity扩展,请在样式中进行更改,如下所示:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

@Override
protected void onCreate(final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Make this activity, full screen
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

    // Hide the Title bar of this activity screen
    getWindow().requestFeature(Window.FEATURE_NO_TITLE);

    setContentView(R.layout.main);

    // MORE INIT STUFF HERE...
}

使用public class MainActivity extends Activity - 代替 - public class MainActivity extends ActionBarActivity

将此主题添加到manifest.xml

中的所有活动中
android:theme="@android:style/Theme.NoTitleBar"
