大多数的Splash界面都是会等待一定时间,然后切换到下一个界面;其实,在这段时间里,可以对系统状况进行检测,比如网络是否通,电源是否充足;或者,预先加载相关数据;
源码示例
AndroidMenifest.xml
<activity android:icon="@drawable/app_icon"
android:screenOrientation="portrait"
android:name=".splashScreen"
android:theme="@android:style/Theme.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
splashScreen.java
public class splashScreen extends Activity {
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.splashscreen);
new Handler().postDelayed(new Runnable() {
public void run() {
Intent intent = new Intent(splashScreen.this, MainActivity.class);
startActivity(intent);
finish();
}
}, 2000);
}
}
