本来我是没有时间学安卓的,然而。。。又是期末大作业,又得把安卓捡起来折腾一下,嗯其实我们的(UI设计师)P图手已经P了好几张图了,我就是把图塞进去再加点跳转什么的就酱。。。
首先的问题就是去掉顶上一堆什么玩意儿。。。弄成全屏的,有两种方法都有效,我现在用的是后者,比较方便。

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)

For 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);      }      ...  }

For 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);  

4. 隐藏所有Activity界面的标题栏

修改AndroidManifest.xml 在application 标签中添加

android:theme=”@android:style/Theme.NoTitleBar”

5. 隐藏所有Activity界面的TitleBar 和StatusBar

修改AndroidManifest.xml 在application 标签中添加

android:theme=”@android:style/Theme.NoTitleBar.Fullscreen”

同样如果只需要给某一个activity隐藏的话只需要在activity标签里面添加就可以了
