下面的文件是activity_main.xml，它与上面的文件MainActivity.java相关联

文件名为activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" 
android:background="@drawable/pic_two">"

<Button
android:id="@+id/badd"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/tvdisplay"
android:layout_alignTop="@+id/bsub"
android:text="@string/but1"
android:textSize="20sp" />

<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/tvdisplay"
android:layout_alignRight="@+id/tvdisplay"
android:text="@string/hello_world"
android:textSize="@dimen/asa" />

<TextView
android:id="@+id/tvdisplay"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/textView2"
android:layout_centerHorizontal="true"
android:layout_marginTop="42dp"
android:gravity="center"
android:text="@string/str1"
android:textColor="@layout/activity_main"
android:textSize="30sp" />

<Button
android:id="@+id/bsub"
android:layout_width="100dp"

android:layout_marginRight="38dp"
android:layout_marginTop="23dp"
android:text="@string/but2"
android:textSize="20sp" />
</RelativeLayout>

然后我创建了与Splash.java相关的Xml文件，即Splash.Xml

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

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />

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

<activity
android:name="com.example.timepass.Splash"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.example.timepass.MainActivity"
android:label="@string/app_name" >

</activity>

</application>

</manifest>

splash.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/pic_background">

</LinearLayout>

现在我想先运行Splash.java文件，然后运行MainActivity.java文件，所以我对Androidmanifest.xml文件做了一些更改 以下是更改，在运行我的程序后，我得到错误“不幸的是，timepass已停止”，其中timepass是我的应用程序名。请解决此问题

AndroidManifest.xml

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

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />

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

<activity
android:name="com.example.timepass.Splash"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.example.timepass.MainActivity"
android:label="@string/app_name" >

</activity>

</application>

</manifest>

从此行中删除

“

：

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

它是这样写的

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

此外，您正在从后台线程启动活动，但该线程不起作用。请在中替换代码：

 runOnUiThread(new Runnable() {
     @Override
     public void run() {
         Intent i =new Intent(Splash.this, MainActivity.class);
         startActivity(i);
     }
 });

---

删除双引号：

Intent i =new Intent("Splash.this,MainActivity.class");
startActivity(i);

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

替换您的代码

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

到

---

您在编写时添加了“错误”。

FYI：您找不到另一个Android问题标题，该标题对问题的说明较少。这就是导致您出现问题的原因：

Intent i=new Intent（“Splash.This，MainActivity.class”）如果不起作用，请告诉我们Splash.javayes中的第35行是什么？我刚才做了，但仍然没有运行，并给出了相同的错误您的代码中有另一个问题，请查看我编辑的答案。您尝试过我改进的答案吗？
Intent i =new Intent("Splash.this,MainActivity.class"); 

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