本文实例讲述了Android编程设置全屏的方法。分享给大家供大家参考,具体如下:
在实际的应用程序开发中,我们有时需要把 Activity 设置成全屏显示,一般情况下,可以通过两种方式来设置全屏显示效果。其一,通过在代码中可以设置,其二,通过manifest配置文件来设置全屏。
其一:在代码中设置(如下)

package xiaohang.zhimeng; import android.app.Activity; import android.content.pm.ActivityInfo; import android.os.Bundle; import android.view.Window; import android.view.WindowManager; public class Activity01 extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super .onCreate(savedInstanceState); //设置为无标题栏 requestWindowFeature(Window.FEATURE_NO_TITLE); //设置为全屏模式 getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); //设置为横屏 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); setContentView(R.layout.main); } } |
但要注意的是:在代码中设置的话,设置无标题和设置全屏的两段代码要放置在 setContentView(R.layout.main); 这段代码的前面。要不然会报错。
其二:在manifest配置文件中设置

<? xml version = "1.0" encoding = "utf-8" ?> < manifest xmlns:android = "http://schemas.android.com/apk/res/android" package = "com.ladygaga.playboy" android:versionCode = "1" android:versionName = "1.0" > < uses-sdk android:minSdkVersion = "8" /> < application android:icon = "@drawable/icon" android:label = "@string/app_name" > < activity android:name = "com.ladygaga.test.ImageSwitcherTest" android:screenOrientation = "sensor" android:label = "@string/app_name" > < intent-filter > < action android:name = "android.intent.action.MAIN" /> < category android:name = "android.intent.category.LAUNCHER" /> </ intent-filter > </ activity > </ application > </ manifest > |

<? xml version = "1.0" encoding = "utf-8" ?> < manifest xmlns:android = "http://schemas.android.com/apk/res/android" package = "com.ladygaga.playboy" android:versionCode = "1" android:versionName = "1.0" > < uses-sdk android:minSdkVersion = "8" /> < application android:icon = "@drawable/icon" android:theme = "@android:style/Theme.NoTitleBar.Fullscreen" android:label = "@string/app_name" > < activity android:name = "com.ladygaga.test.ImageSwitcherTest" android:label = "@string/app_name" > < intent-filter > < action android:name = "android.intent.action.MAIN" /> < category android:name = "android.intent.category.LAUNCHER" /> </ intent-filter > </ activity > </ application > </ manifest > |
在相应的Activity中节点中添加属性:
复制代码 代码如下:
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
即可以设置某个Activity全屏显示。若设置成 android:theme="@android:style/Theme.NoTitleBar" 即是只是设置成无标题状态。
希望本文所述对大家Android程序设计有所帮助。
