启屏页最佳实践
1. 秒开:主题设置windowBackground,避免启动黑白闪屏
<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar"> <item name="android:windowBackground">@mipmap/background_splash</item> <item name="android:windowFullscreen">true</item> </style>
|
2. 不设置setContentView,减少启动时间
3. 如何更改背景,比如显示首发:在原背景图上,制作一张带“首发”字体的图片,然后在增加一个style主题,然后在onCreate里setTheme()
4. 如何做postDelay后启动MainActivity
5. Show me the code:
public class SplashActivity extends Activity {
@Override protected void onCreate(Bundle savedInstanceState) { // setTheme(R.style.SplashThemeHuawei); // 更改背景 super.onCreate(savedInstanceState); getWindow().getDecorView().postDelayed(new Runnable() { @Override public void run() { startActivity(new Intent(SplashActivity.this, MainActivity.class)); finish(); } }, 1000); }
@Override protected void onDestroy() { super.onDestroy(); getWindow().getDecorView().getHandler().removeCallbacksAndMessages(null); } }
