[开机画面]如何全屏幕显示的图像？ [英] [Splash Screen]How to show an image in full screen?

问题描述

我想打一个启动画面在我的应用程序，我需要知道如何全屏幕显示图像。这可以通过我的XML或Java code做？如何？ 现在我只是做这样的：

 公共类闪屏延伸活动{

    私有静态最终诠释STOPSPLASH = 0;

    私有静态最后长SPLASHTIME = 5000;



    私人处理程序splashHandler =新的处理程序（）{
    @覆盖
    公共无效的handleMessage（信息MSG）{
    开关（msg.what）{
    案例STOPSPLASH：
    //从视图中删除闪屏
    意向意图=新的意图（SplashScreen.this，jetpack.class）;
    startActivity（意向）;
    打破;
    }
    super.handleMessage（MSG）;
    }
    };



    @覆盖

    公共无效的onCreate（包savedInstanceState）{
    super.onCreate（savedInstanceState）;
    的setContentView（R.layout.splash_screen）;
    消息味精=新的Message（）;
    msg.what = STOPSPLASH;
    splashHandler.sendMessageDelayed（味精，SPLASHTIME）;
    }
    }
 

怎么会这样splash_screen.xml？ 感谢您的帮助。

解决方案

 ＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT; LinearLayout中的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
机器人：方向=垂直
机器人：layout_width =FILL_PARENT
机器人：layout_height =FILL_PARENT＆GT;
＆LT; ImageView的机器人：layout_width =FILL_PARENT
    机器人：layout_height =FILL_PARENT
    机器人：SRC =@可绘制/图像/＆GT;
＆LT; / LinearLayout中＆GT;
 

和在code添加

  this.requestWindowFeature（Window.FEATURE_NO_TITLE）;
 

的setContentView（R.layout.splash_screen）之前;

I want to make a splash screen in my application, for that i need to know how to show an image in full screen. This could me made by XML or Java code ? And how? For now i just made this:

public class SplashScreen extends Activity {

    private static final int STOPSPLASH = 0;

    private static final long SPLASHTIME = 5000;



    private Handler splashHandler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
    switch (msg.what) {
    case STOPSPLASH:
    //remove SplashScreen from view
    Intent intent = new Intent(SplashScreen.this, jetpack.class);
    startActivity(intent);
    break;
    }
    super.handleMessage(msg);
    }
    };



    @Override

    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash_screen);
    Message msg = new Message();
    msg.what = STOPSPLASH;
    splashHandler.sendMessageDelayed(msg, SPLASHTIME);
    }
    }

How can be this splash_screen.xml ? Thank you for your help.

解决方案

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" 
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    android:src="@drawable/image" />
</LinearLayout>

and in the code add

this.requestWindowFeature(Window.FEATURE_NO_TITLE);

before setContentView(R.layout.splash_screen);
