Android中设置全屏的方法

1，修改onCreate函数

package com.android.myfirstandroidapp;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.Window;import android.view.WindowManager;import android.widget.Button;import android.widget.TextView;import android.widget.Toast;import android.widget.LinearLayout;public class MyFirstAndroidAppActivity extends Activity {    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);                     //去掉窗口的标题      requestWindowFeature(Window.FEATURE_NO_TITLE);      //设置窗口布局为全屏      getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);            // 使用布局文件main.xml的例子      setContentView(R.layout.main);                final Button btn = (Button)findViewById(R.id.button1);        btn.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubToast.makeText(MyFirstAndroidAppActivity.this, "Buttton", Toast.LENGTH_SHORT).show();}});    }}

2，修改AndroidManifest.xml文件

添加一行配置：android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"      package="com.android.myfirstandroidapp"      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=".MyFirstAndroidAppActivity"        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></manifest>
