Android Full Screen

안드로이드 전체화면(Full Screen) 사용하기

1. AndroidManifest.xml 에서 Full Screen 설정하기

타이틀바와 상태바를 모두 제거하고자 한다면...

<activity android:name=".MainActivity"
      android:theme="@android:style/Theme.NoTitleBar.Fullscreen"  >


상태바는 남겨두고 타이틀바만 제거하고자 한다면...

<activity android:name=".MainActivity"
      android:theme="@android:style/Theme.NoTitleBar"  >

2. 프로그램 코드상에서 동적으로 Full Screen 설정하기

MainActivity.java

 package com.example.androidapp;

import android.app.Activity;
import android.graphics.Rect;
import android.os.Bundle;
import android.util.Log;
import android.view.MotionEvent;
import android.view.Window;
import android.view.WindowManager;
import android.widget.TextView;

public class MainActivity extends Activity {
	
	@Override
	public void onCreate(Bundle savedInstanceState) {
	    super.onCreate(savedInstanceState);
		
	    requestWindowFeature(Window.FEATURE_NO_TITLE);
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                     WindowManager.LayoutParams.FLAG_FULLSCREEN);
            //int width = getWindowManager().getDefaultDisplay().getWidth();
            //int height = getWindowManager().getDefaultDisplay().getHeight();

	    setContentView(new Tank(this));
	}

}
