我对android还是很陌生,我正在尝试通过遵循网站上的教程来实现启动屏幕。
我做了所有写在这里的东西,但是当我运行我的应用程序时,初始屏幕没有出现。
我从StackOverflow的许多问题中获得了参考,但这似乎不起作用
下面是我的“ activity_splash”文件,位于“ res-> layout-> activity_splash.xml”
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/googleg_standard_color_18" >
<ImageView
android:id="@+id/imgLogo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:src="@drawable/image_offline" />
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:textSize="12dp"
android:textColor="#454545"
android:gravity="center_horizontal"
android:layout_alignParentBottom="true"
android:text="www.androidhive.info" />
下面是我在MainActivity.java文件旁边的“ SplashScreen.java”文件
// Splash screen timer
private static int SPLASH_TIME_OUT = 3000;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
new Handler().postDelayed(new Runnable() {
/*
* Showing splash screen with a timer. This will be useful when you
* want to show case your app logo / company
*/
@Override
public void run() {
// This method will be executed once the timer is over
// Start your app main activity
Intent i = new Intent(SplashScreen.this, MainActivity.class);
startActivity(i);
// close this activity
finish();
}
}, SPLASH_TIME_OUT);
}
*
*下面是我的“ AndroidManifest.xml”文件**
<?xml version="1.0" encoding="utf-8"?>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

由于您将MainActivity
作为manifest
中的启动器活动,因此未显示您的启动屏幕
更改您的manifest
代码:
<activity android:name=".SplashScreen">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity" />
答案 1 :(得分:0)
bro首先要启动活动,您必须先使其启动,我正在修改您的代码,而改用它。替换您的清单代码进行启动活动。并从主要活动中删除意图过滤器
<activity android:name=".SplashScreen" >
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
答案 2 :(得分:0)
您只需要在初始屏幕中设置意图过滤器。 像这样。
<activity android:name=".SplashScreen">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
MainActivity不需要删除它的意图过滤器。
