Android启动页设置_android设置启动页

第一步：创建LunchActivity

public class LunchActivity extends AppCompatActivity {
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate( savedInstanceState );
        new Thread( new Runnable( ) {
            @Override
            public void run() {
                //耗时任务，比如加载网络数据
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        startActivity(Intent(this, MainActivity::class.java))
                    }
                });
            }
        } ).start();
    }
 
}

第二步：AndroidManifast文件设置LunchActivity为第一个页面，并添加主题

<activity
    android:name=".LunchActivity"
    android:theme="@style/LunchTheme">
    <intent-filter>
        <action android:name="android.intent.action.MAIN"/>
        <category android:name="android.intent.category.LAUNCHER"/>
    </intent-filter>
</activity>

 主题设置

<style name="LunchTheme" parent="Theme.AppCompat">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
    <item name="android:windowBackground">@drawable/background_gradient</item>
</style>
