Question

就像标题告诉我在我的Android Galaxy Ace S5830i上运行这个应用程序时遇到问题。

我刚刚在eclipse中创建了一个新的Android应用程序。
在First中添加了Splash.java - ＆gt; src - ＆gt; com.example.first - ＆gt; Splash.java
添加了布局res - ＆gt; layout - ＆gt; splash.xml（它基本上只是eclipse设置的activity_fullscreen.xml的副本，只是按钮已被删除）
在清单

每当我在设备上启动应用程序时，它都会崩溃＆＃34;应用程序First（进程com.example.first）意外停止。请再试一次。＆＃34;

我可以告诉你，启动启动时会启动启动活动，但在尝试启动其他活动时会崩溃。

Splash.java

    package com.example.first;

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

public class Splash extends Activity{

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

    Thread timer = new Thread(){
        public void run(){
            try{
                sleep(5000);
            }catch(InterruptedException e){
                e.printStackTrace();
            }finally{
                Intent start = new Intent("com.example.first.FullscreenActivity");
                startActivity(start);
            }
        }
    };
    timer.start();
}

}

splash.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"

Answer 1

在splash.class上，更改

Intent start = new Intent("com.example.first.FullscreenActivity");

到

Intent start = new Intent(Splash.this,com.example.first.FullscreenActivity.class);

您将manifest.xml更改为以下

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

<uses-sdk
    android:minSdkVersion="9"
    android:targetSdkVersion="17" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.first.Splash"
        android:configChanges="orientation|keyboardHidden|screenSize"
        android:label="@string/app_name"
        android:theme="@style/FullscreenTheme" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="com.example.first.FullscreenActivity"
        android:configChanges="orientation|keyboardHidden|screenSize">
    </activity>

</application>

</manifest>
