java - 启动屏幕后不显示主要 Activity

Question

我理解成千上万的人说“不要使用飞溅”，我明白了，但应用程序不是那么大，我只是想知道我做错了什么我认为这是我的 list 的问题但在我的启动画面显示后，当它应该进入主页时，我收到错误“抱歉!应用程序 Grifball(进程 com.grifball.info)已意外停止。请重试。

这是我的 list 。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.grifball.info"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="8" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

     <activity android:name="Splash">
                    <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>       
    <activity
        android:name="MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.grifball.info.MAINACTIVITY" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

</application>

</manifest>

这是我的 Splash 的 Java

package com.grifball.info;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

public class Splash extends Activity{

@Override
protected void onCreate(Bundle startup) {
    // TODO Auto-generated method stub
    super.onCreate(startup);
    setContentView(R.layout.splash);

    Thread timer = new Thread(){

        public void run(){

            try{
                sleep(5000);
            }catch(InterruptedException e){
                e.printStackTrace();
            }finally{
                Intent openMainActivity = new Intent("com.grifball.info.MAINACTIVITY");
                startActivity(openMainActivity);
            }
        }

    };
    timer.start();
}

}

这是 XML

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


</LinearLayout>

这是我的原木猫

Answer 1

在“AndroidManifest.xml”中，您应该更改此内容:

<action android:name="com.grifball.info.MAINACTIVITY" />

对此:

<action android:name="android.intent.action.MAINACTIVITY" />

并且，在“Splash.java”中，您应该更改:

Intent openMainActivity = new Intent("com.grifball.info.MAINACTIVITY");

对此:

Intent openMainActivity = new Intent(Splash.this, MainActivity.class);
