去掉状态栏的代码:
getWindow.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
我们平时这样写
<activity
android:name=".SplashActivity"
android:screenOrientation="portrait"
android:theme="@style/ThemeSplash">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<style name="ThemeSplash" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowBackground">@android:color/white</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
<item name="windowActionBar">false</item>
//一定要,否则有状态栏显示,不能全屏
<item name="windowNoTitle">true</item>
</style>
然后是SplashAcitivity的布局文件,用一张图片作为背景
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@mipmap/bg_splash"
tools:context="com.example.makeapp.SplashActivity">
</LinearLayout>
然后是SplashActivity的代码,延迟2秒跳转到主页面
public class SplashActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
//延迟2S跳转
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
Intent intent = new Intent(SplashActivity.this, MainActivity.class);
startActivity(intent);
finish();
}
}, 2000);
}
}
但是此时你会发现一个问题,就是点击进入app后,会先白屏或是黑屏后,然后才会进入splash页面。
正确的姿势
我们只需要对style中的ThemeSplash进行改动,只是给windowbackground设置背景就ok:
<style name="ThemeSplash" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowBackground">@drawable/你的splash图片</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
<item name="windowActionBar">false</item>
//一定要,否则有状态栏显示,不能全屏
<item name="windowNoTitle">true</item>
</style>
或者也可以这样:
<style name="LuncherTheme" parent="@android:style/Theme.NoTitleBar.Fullscreen">
<item name="android:windowBackground">@drawable/splash</item>
</style>
ok,这样就会是app秒起,而不会闪屏了
