设置android 应用开发的欢迎界面

对刚才设置好的内容做一下整理:

配置欢迎界面的xml：

layout创建下start.xml

start.xml内容：

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

　　开发 android:background="@drawable/start_background"使用文件

在drawable下创建start_background.xml

start_background.xml内容：

<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
    android:scaleType="fitStart"
    android:src="@drawable/view480_800" />

 

创建StartActivity.java

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.animation.AlphaAnimation;
import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;

public class StartActivity extends Activity {
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		
		final View view=View.inflate(this, R.layout.start, null);
		setContentView(view);
		
		AlphaAnimation alphaAnimation=new AlphaAnimation(0.3f, 1.0f);
		alphaAnimation.setDuration(2000);
		view.startAnimation(alphaAnimation);
		alphaAnimation.setAnimationListener(new AnimationListener() {
			
			@Override
			public void onAnimationStart(Animation arg0) {
				
			}
			
			@Override
			public void onAnimationRepeat(Animation arg0) {
				
			}
			
			@Override
			public void onAnimationEnd(Animation arg0) {
				Intent intent=new Intent();
				intent.setClass(StartActivity.this, MainActivity.class);
				startActivity(intent);
				finish();
			}
		});
		
	}
}

　

　最后设置AndroidManifest.xml

   <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name="StartActivity"
            android:label="@string/app_name" android:theme="@android:style/Theme.Holo.Light.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="MainActivity"></activity>
    </application>

　　完成！
