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() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.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>
