Android 简单闪屏
这里我们主要就是介绍一下闪屏的。下面的例子里我们主要就是用到了android中的Activity;Intent;Bundle;util.Log;KeyEvent;这些，下面我们就看看例子中是怎么实现闪屏的吧。Java代码：
package com.demo;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.KeyEvent;
public class test extends Activity {
private long m_dwSplashTime=3000;
private boolean m_bPaused=false;
private boolean m_bSplashActive=true;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread splashTimer=new Thread()
{
public void run(){
try{
//wait loop
long ms=0;
while(m_bSplashActive && ms< m_dwSplashTime){
sleep(100);
if(!m_bPaused)
ms+=100;
}
startActivity(new Intent("com.google.app.splashy.CLEARSPLASH"));
}
catch(Exception ex){
Log.e("Splash",ex.getMessage());
}
finally{
finish();
}
}
};
splashTimer.start();
}
@Override
protected void onPause() {
super.onPause();
m_bPaused=true;
}
@Override
protected void onResume() {
super.onResume();
m_bPaused=false;
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
super.onKeyDown(keyCode, event);
switch(keyCode){
case KeyEvent.KEYCODE_MENU:
m_bSplashActive=false;
break;
case KeyEvent.KEYCODE_BACK:
/*两种退出方法*/
/* System.exit(0);*/
/* android.os.Process.killProcess(android.os.Process.myPid());*/
android.os.Process.killProcess(android.os.Process.myPid());
break;
default:
break;
}
return true;
}
}
AndroidManifest.xml 这里面配置很重要
Java代码：
< ?xml version="1.0" encoding="utf-8"? >
< manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.demo"
android:versionCode="1"
android:versionName="1.0" >
< application android:icon="@drawable/icon" android:label="@string/app_name" >
< activity android:name="test" 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=".MainMenu" android:label="@string/app_name" >
< intent-filter >
< action android:name="com.google.app.splashy.CLEARSPLASH" / >
< category android:name="android.intent.category.DEFAULT" / >
< /intent-filter >
< /activity >
< /application >
< /manifest >
