Question

我正在使用Jdeveloper 11.1.2.4.0来创建splashscreen ..我已经按照http://www.androidaspect.com/2012/12/android-splash-screen-tutorial.html中所述的每个步骤进行了

但我仍然无法解决问题。

这是我的splash.java（主要活动）

package mobile;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.view.Window;


public class Splash extends Activity {
     private long ms=0;
     private long splashTime=2000;
     private boolean splashActive = true;
     private boolean paused=false;

    /**
     * @param savedInstanceState
     */

     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);

        //Hides the titlebar
         this.requestWindowFeature(Window.FEATURE_NO_TITLE);

         setContentView(R.layout.Splash);

        Thread mythread = new Thread() {
             public void run() {
                 try {
                     while (splashActive && ms < splashTime) {
                         if(!paused)
                             ms=ms+100;
                         sleep(100);
                     }
                 } catch(Exception e) {}
                 finally {
                    Intent intent;
                    intent = new Intent(Splash.this, Home.class);
                    startActivity(intent);
                 }
             }
         };
         mythread.start();
     }
 }

的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.company.splash_screen">
  <uses-sdk/>

</manifest>

在res / layout /文件夹中，我有splash.xml

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

    <ImageView
         android:id="@+id/image"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:src="@drawable/background" />

    <ProgressBar
         android:id="@+id/progressBar1"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_below="@id/image"
         android:layout_gravity="center_horizontal" >
     </ProgressBar>

</LinearLayout>

和home.xml（第二个活动）

<?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" >

    <TextView
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_gravity="center"
         android:layout_marginTop="20dip"
         android:text="HomeScreen"
         android:textAppearance="?android:attr/textAppearanceLarge" />

</LinearLayout>

在两个.java文件（splash.java＆amp; home.java）中，错误显示在setContentView（R.layout.Splash）;和setContentView（R.layout.Home）; RESP ...

Answer 1

您的R.java文件未正确生成。

清理项目并重新构建。

项目 - ＆gt;清洁

如果这不能解决问题，检查XML文件中的错误。 XML文件中的错误会阻止R.java的生成。

一旦确定一切正确，您可以清理项目并重新构建它。

或者您可以手动删除 R.java，然后构建项目，这将再次重新生成R.java

注意：从不使用 import android.r ，即使您看到eclipse提示它。

Answer 2

你输入它，

将此内容放入导入

import (Your package Name ex:com.android.user).R

并确保你在（Project-＆gt; gen＆gt; projectname-＆gt; R.java）中有R.java文件，如果你不去（右键单击项目 - ＆gt; android工具 - ＆gt;修复项目属性。）

“R”无法在setContentView（R.layout.Splash）中解析;
