安卓开发软件欢迎界面怎么做
安卓开发软件欢迎界面的代码如下：
1、制作一张启动图片splash.png，放置在res-drawable-hdpi文件夹中。
2、新建布局文件splash.xml
?xml version="1.0" encoding="utf-8"?
RelativeLayout xmlns:android=""
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/splash"
TextView
android:id="@+id/versionNumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_marginBottom="26dp"
android:layout_marginRight="52dp"
android:text="version 1.0"
android:textColor="" /
/RelativeLayout
这里我们把上一步制作的图片作为启动界面的背景图，然后在界面底部显示当前程序的版本号。
3、新建SplashActivity，在Oncreate中添加以下代码：
PackageManager pm = getPackageManager();
try {
PackageInfo pi = pm.getPackageInfo("com.lyt.android", 0);
TextView versionNumber = (TextView) findViewById(R.id.versionNumber);
versionNumber.setText("Version " + pi.versionName);
} catch (NameNotFoundException e) {
e.printStackTrace();
}
new Handler().postDelayed(new Runnable(){
@Override
public void run() {
Intent intent = new Intent(SplashActivity.this,SplashScreenActivity.class);
startActivity(intent);
SplashActivity.this.finish();
}
}, 2500);
4、 修改Manifest文件，将启动界面Activity改为默认启动，并且设置标题栏不可见。
manifest xmlns:android=""
package="com.example.sinaweibo"
android:versionCode="1"
android:versionName="1.0"
uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" /
application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@android:style/Theme.NoTitleBar"
activity
android:name=".MainActivity"
android:label="@string/title_activity_main"
intent-filter
action android:name="android.intent.action.MAIN" /
category android:name="android.intent.category.LAUNCHER" /
/intent-filter
/activity
activity
android:name=".MainActivity1"
android:label="@string/title_activity_main_activity1"
intent-filter
action android:name="android.intent.action.MAIN" /
category android:name="android.intent.category.LAUNCHER" /
/intent-filter
/activity
/application
/manifest
这样打开应用后等待2.5秒就进入第二个activity MainActivity了。
大家好，我开发的安卓APP欢迎界面的图片不能布满整个手机屏幕，还有程序运行到手机上出现两个APP客
首先不知道你说的 充满整个屏幕是什么意思
所以我就全说了；第一种，填充整个屏幕 包括显示时间和电量的状态栏
这个需要你在AndroidMainfest.xml文件中 声明这个activity的时候
加入Android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
说明这个activity的风格是无状态了，充满整个屏幕的
第二种，就是你仅仅需要你的开机动画充满现有activity的页面，LinearLayout的属性中加入
android:layout_width="fill_parent"
android:layout_height="fill_parent"
既可以实现
