android - 应用程序从 SplashScreenActivity(全屏)移动到 MainActivity(非全屏)时出现

Question

我有一个全屏的 SplashScreenActivity，它会在 3 秒后移动到 MainActivity。

styles.xml 用于 SplashScreenActivity :

<!-- Theme for Splash with no Action bar full screen -->
<style name="splash_screen" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

MainActivity 的

styles.xml:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
    <item name="vpiCirclePageIndicatorStyle">@style/CustomCirclePageIndicator</item>
</style>

当应用程序从SplashScreenActivity移动到MainActivity时，因为它从全屏移动到非全屏，Layout出现然后移动有点向下。

我已经用过了

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN);
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

还有

android:paddingTop="25dp"

但运气不好。

谁能解决这个问题？？

SplashScreenActivity:

    public class SplashScreenActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.splash);

        callWeatherService(this);
        delayedTask();
    }

                startActivity(new Intent(this, MainActivity.class));
            }
        };
        new Handler().postDelayed(splashRunnable, Numerics.THREE_THOUSAND);
    }

    public void onEventMainThread(WeatherModel weather) {
        if (weather != null) {
            Preferences.getIns().saveWeather(weather);

Answer 1

你有太多什么都不做的行。这是我的示例，它按预期工作:在 list 中什么都不做:

 <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme">
        <activity android:name=".SplashActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" />
</application>

在我的 styles.xml 中什么都不做，只是从正确的主题扩展

 <style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
           //nothing to do with fullscreen it all extended
</style>

Splash Activity 只是 LinearLayout 。主 Activity 根本没有覆盖窗口，您已经扩展了正确的主题。

public class MainActivity extends AppCompatActivity {

    private DrawerLayout mDrawerLayout;
    private Toolbar toolbar;
    private ActionBarDrawerToggle mDrawerToggle;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        toolbar = (Toolbar) findViewById(R.id.main_page_toolbar_parent);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(false);
        getSupportActionBar().setTitle(null);
        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.action_settings, R.string.app_name) {

            /** Called when a drawer has settled in a completely closed state. */
            public void onDrawerClosed(View view) {
                super.onDrawerClosed(view);
                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
            }

            /** Called when a drawer has settled in a completely open state. */
            public void onDrawerOpened(View drawerView) {
                super.onDrawerOpened(drawerView);
                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
            }
        };
        mDrawerLayout.setDrawerListener(mDrawerToggle);
        getSupportActionBar().setHomeButtonEnabled(true);
        getSupportFragmentManager().beginTransaction().replace(R.id.container_frame, new MainActivityFragment()).commit();
    }
}

它适用于我需要 Splash 的所有应用程序。
