Question

It seems that Android has a default splash screen. I didn t make any splash screen but every time I open my application, a splash screen appears. The title bar of my splash screen contains a string which is the name of my application. It also uses the same background as what I ve set on my application.

为什么我的申请显示有点闪?? 难道这是安乐吗? 我检查了其他人开发的其他申请,没有刀切。

我如何去掉我间谍屏幕标题栏上的插 the? 我怎么能够改变我的猛烈屏幕的背景,同时又不影响我其他活动的背景?

我第一次活动的样本:

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate();
    setContentView(R.layout.main);
    //initialize variables
    txtView1 = (TextView)this.findViewById(R.id.txtView1);
    txtView2 = (TextView)this.findViewById(R.id.txtView2);
    ...
    //register broadcast receiver
    ...
}

public void onResume()
{
    super.onResume();
    //read bundle if a bundle exists
    ...
}

Answer 1

我没有做过任何猛烈的筛查,但每次我开放我的申请时,都会看到一个闪亮的屏幕。

氯乙烯不会在应用中添加闪电。

我的间谍屏幕标题栏载有我的申请名称。它还利用了我在申请中阐述的同样背景。

这是你的活动之一。具体来说,它包含以下内容:<intent-filter>。

        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>

Why does my application shows a splash screen?

Because that is what you wrote. Whatever activity you have tied to the MAIN/LAUNCHER <intent-filter> is causing this effect. You need to read your manifest file, identify this activity, take a look at the activity code, and determine what it is that you wrote.

Is this a default on Android?

No.

Answer 2

The way you describe it sounds like your activity s onCreate method is taking a long time to run. Make sure you don t perform long-running operations directly on the UI thread.
