大多數(shù)的Splash界面都是會等待一定時間,然后切換到下一個界面;其實,在這段時間里,可以對系統(tǒng)狀況進行檢測,比如網(wǎng)絡是否通,電源是否充足;或者,預先加載相關數(shù)據(jù);
源碼示例
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);
}
}
