Android基础教程之-------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?
"1.0" encoding="utf-8"?>        
"http://schemas.android.com/apk/res/android"    
            package="com.android.tutor"    
            android:versionCode="1"    
            android:versionName="1.0">        
        "@drawable/icon" android:label="@string/app_name">        
                ".OpenGl_Lesson1"    
                                    android:theme="@android:style/Theme.NoTitleBar.Fullscreen"    
                                    android:label="@string/app_name">        
                                
                                "android.intent.action.MAIN" />        
                                "android.intent.category.LAUNCHER" />        
                                
                        
                
        "7" />        
        
"1.0" encoding="utf-8"?>
"http://schemas.android.com/apk/res/android"
            package="com.android.tutor"
            android:versionCode="1"
            android:versionName="1.0">
        "@drawable/icon" android:label="@string/app_name">
                ".OpenGl_Lesson1"
                        android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
                                    android:label="@string/app_name">
                        
                                "android.intent.action.MAIN" />
                                "android.intent.category.LAUNCHER" />
                        
                
        
        "7" />
    

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！ 谢谢~
