- 主题:用户界面之Splash(闪屏启动)
-
用Splash做闪屏启动界面(实例):
实现效果:
APP启动全屏显示一张背景图片,2s后跳转到MainActivity。
AndroidManifest.xml:
(在AndroidManifest中使用android:theme=”@android:style/Theme.NoTitleBar.Fullscreen”定义主题为无标题栏全屏显示。再在定义第一个Activity启动为SplashActivity)
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.demo2"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="14" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
<activity
android:name="com.example.demo2.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.example.demo2.MainActivity">
</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="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@drawable/a2" >
</LinearLayout>
splash.xml中涉及的图片资源a2:
SplashActivity.java:
(实现定时2s跳转)
package com.example.demo2;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.widget.Button;
public class SplashActivity extends Activity {
Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
new Handler().postDelayed(new Runnable(){
@Override
public void run() {
// TODO Auto-generated method stub
Intent intent = new Intent(SplashActivity.this,MainActivity.class);
startActivity(intent);
finish();
}
}, 2000);
}
}
