从SplashScreenActivity（全屏）移动到MainActivity（非全屏）时应用程序崩溃

Question

我有SplashScreenActivity全屏，3秒后移动到MainActivity。

styles.xml的

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>

styles.xml的

MainActivity：

<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>

当应用从全屏移动到非全屏时，SplashScreenActivity从MainActivity移动到Layout， 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); 会出现，然后向下移动一点。

我已经使用过了

android:paddingTop="25dp"

以及

SplashScreenActivity

但没有运气。

任何人都可以提供这个问题的解决方案吗？

你有太多的行无效。这是我的例子，按预期工作： 在清单中没有：

 <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中没有任何内容，只需从正确的主题扩展

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

启动活动仅LinearLayout。 主要活动根本没有覆盖窗口，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。
