【中文标题】安卓启动画面【英文标题】：Android Splash Screen 【发布时间】：2013-03-05 07:51:59 【问题描述】：这是我的包资源管理器中的内容，所以让我们从顶部开始 并努力解决我认为它所在的问题..
MainActivity.java -
package com.drg.idoser;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class MainActivity extends Activity
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
@Override
public boolean onCreateOptionsMenu(Menu menu)
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
现在 SplashActivity.java
package com.drg.idoser;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.Window;
import android.view.WindowManager;
public class SplashActivity extends Activity
private static String TAG = SplashActivity.class.getName();
private static long SLEEP_TIME = 5; // Sleep for some time
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE); // Removes title bar
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); // Removes notification bar
setContentView(R.layout.splash);
// Start timer and launch main activity
IntentLauncher launcher = new IntentLauncher();
launcher.start();
private class IntentLauncher extends Thread
@Override
/**
* Sleep for some time and than start new activity.
*/
public void run()
try
// Sleeping
Thread.sleep(SLEEP_TIME*1000);
catch (Exception e)
Log.e(TAG, e.getMessage());
// Start main activity
Intent intent = new Intent(SplashActivity.this, MainActivity.class);
SplashActivity.this.startActivity(intent);
SplashActivity.this.finish();
activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_
android:layout_
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" >
<TextView
android:layout_
android:layout_
android:text="@string/hello_world" />
</RelativeLayout>
splash.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_
android:background="@drawable/splash_bg"
android:layout_
android:orientation="vertical" >
</LinearLayout>
AndroidManafest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.drg.idoser"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
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.drg.idoser.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
现在我认为我的问题在于 AndroidManafest.xml 当我从我的应用程序启动我的应用程序时，我认为我没有在 AndroidManafest.xml电话它跳转到 activity_main.xml 而不是 splash.xml 我是 android 应用程序的新手，所以我似乎找不到我的问题，但我需要我的启动屏幕显示 5 秒如果有人拥有 TeamViwer 并愿意帮助我发布我的会话信息，如果它会更快的话。
【问题讨论】：
对于那些可能会复制上面启动屏幕代码的人，强烈建议NOT使用线程。相反，使用处理程序。查看链接***.com/a/12195205/361100 看到这个github.com/meetmehdi/GoodSplash 【参考方案1】：将您的<application> 标记更改为以下内容。您没有声明 SplashActivity，并将 MainActivity 设置为启动器 Activity。
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.drg.idoser.SplashActivity"
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.drg.idoser.MainActivity"
android:label="@string/app_name" />
</application>
【讨论】：
我试了一下说请等25分钟我不知道为什么 非常适合我。谢谢【参考方案2】：实现启动屏幕的最佳方法是创建一个新的活动，每次启动应用程序时都会显示。
public class SplashScreen extends Activity
private Handler mHandler;
private Runnable myRunnable;
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
// Just create simple XML layout with i.e a single ImageView or a custom layout
setContentView(R.layout.splash_screen_layout);
mHandler = new Handler();
myRunnable = new Runnable()
@Override
public void run()
Intent intent = new Intent(SplashScreen.this, MainActivity.class);
startActivity(intent);
finish();
;
@Override
public void onBackPressed()
// Remove callback on back press
if (mHandler != null && myRunnable != null)
mHandler.removeCallbacks(myRunnable);
super.onBackPressed();
@Override
protected void onPause()
// Remove callback on pause
if (mHandler != null && myRunnable != null)
mHandler.removeCallbacks(myRunnable);
super.onPause();
@Override
protected void onResume()
// Attach and start callback with delay on resume
if (mHandler != null && myRunnable != null)
mHandler.postDelayed(myRunnable, ConstantValues.SPLASH_TIME_OUT);
super.onResume();

【参考方案3】：您可以像这样轻松访问启动画面。比如
public class MainActivity extends Activity
private ImageView splashImageView;
private boolean splashloading = false;
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
splashImageView = new ImageView(this);
splashImageView.setScaleType(ScaleType.FIT_XY);
splashImageView.setImageResource(R.drawable.ic_launcher);
setContentView(splashImageView);
splashloading = true;
Handler h = new Handler();
h.postDelayed(new Runnable()
public void run()
splashloading = false;
// set your layout file in below
setContentView(R.layout.activity_main);
, 3000);
它将 100% 有效。

完成了兄弟！感谢您的反馈！【参考方案5】：@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Thread th = new Thread(new Runnable() /*create a new thread */
@Override
public void run() /*
* The purpose of this thread is to
* navigate from one class to another
* after some time
*/
try
Thread.sleep(5000);
catch (InterruptedException e)
/*
* We are creating this new thread because we don’t
* want our main thread to stop working for that
* time as our android stop working and some time
* application will crashes
*/
e.printStackTrace();
finally
Intent i = new Intent(MainActivity.this,
Splash_Class.class);
startActivity(i);
finish();
);
th.start(); // start the thread
