Android中两种设置全屏的方法!!!
在开发中我们经常需要把我们的应用设置为全屏，这里我所知道的有俩中方法，一中是在代码中设置，另一种方法是在配置文件里改！
一、在代码中设置:
view plaincopy to clipboardprint?
package com.android.tutor;??
import android.app.Activity;??
import android.os.Bundle;??
import android.view.Window;??
import android.view.WindowManager;??
public class OpenGl_Lesson1 extends Activity {??
??? public void onCreate(Bundle savedInstanceState) {??
??????? super.onCreate(savedInstanceState);??
?????? //无title????
?????? requestWindowFeature(Window.FEATURE_NO_TITLE);????
??????? //全屏????
?????? getWindow().setFlags(WindowManager.LayoutParams. FLAG_FULLSCREEN ,??????
????????????????????? WindowManager.LayoutParams. FLAG_FULLSCREEN);???
???????????
??????? setContentView(R.layout.main);??
??? }??
}
package com.android.tutor;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
public class OpenGl_Lesson1 extends Activity {
??? public void onCreate(Bundle savedInstanceState) {
??????? super.onCreate(savedInstanceState);
?????? //无title
?????? requestWindowFeature(Window.FEATURE_NO_TITLE);
??????? //全屏
?????? getWindow().setFlags(WindowManager.LayoutParams. FLAG_FULLSCREEN ,???
????????????????????? WindowManager.LayoutParams. FLAG_FULLSCREEN);
????????
??????? setContentView(R.layout.main);
??? }
}
在这里要强调一点，设置全屏的俩段代码必须在setContentView(R.layout.main) 之前，不然会报错。
二、在配置文件里修改(android:theme="@android:style/Theme.NoTitleBar.Fullscreen"):
view plaincopy to clipboardprint?
<?xml version="1.0" encoding="utf-8"?>??
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
????? package="com.android.tutor"
????? android:versionCode="1"
????? android:versionName="1.0">??
??? <application android:icon="@drawable/icon" android:label="@string/app_name">??
??????? <activity android:name=".OpenGl_Lesson1"
????????????????? android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
????????????????? 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>??
??? <uses-sdk android:minSdkVersion="7" />??
</manifest>??
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
????? package="com.android.tutor"
????? android:versionCode="1"
????? android:versionName="1.0">
??? <application android:icon="@drawable/icon" android:label="@string/app_name">
??????? <activity android:name=".OpenGl_Lesson1"
??????? ??? android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
????????????????? 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>
??? <uses-sdk android:minSdkVersion="7" />
</manifest>
在这里我还想说明一下，用前者在我们应用运行后，会看到短暂的状态栏，然后才全屏，而第二种方法是不会有这种情况的，所以我建议
大家使用后者！
