一、解决第一次启动应用黑屏或者白屏的方法:
通过单独设置启动页面的主题:
<activity android:name=".activity.SpayActivity"
android:theme="@style/Theme.AppStartLoadTranslucent"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<style name="Theme.AppStartLoadTranslucent" parent="Theme.AppCompat.Light.NoActionBar">二、设置全屏和无标题
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowNoTitle">true</item>
<item name="colorPrimary">@color/white</item>
</style>
requestWindowFeature(Window.FEATURE_NO_TITLE);
//全屏
getWindow().setFlags(WindowManager.LayoutParams. FLAG_FULLSCREEN ,
WindowManager.LayoutParams. FLAG_FULLSCREEN);
setContentView(R.layout.activity_play);
