我通过一个简单的 Intent 调用一个 Activity :

Intent startNewActivityOpen2 = new Intent(this, TransitionLandscape.class);
if (extras != null) {
        if (!extras.isEmpty()) {

           startNewActivityOpen2.putExtras(extras);
        }
}

startActivity(startNewActivityOpen2);

当前 Activity 也是 TransistionLandscape.class 重要吗？当我开始新 Activity 时，应用程序退出(没有崩溃)。通过调试器，永远不会调用新 Activity :(永远不会调用 onCreate in)

从文档来看，好像一个activity是可以调用自己的。

此外，调用:

recreate() 

不是去新的 Activity，而是导致应用程序退出(没有崩溃)。

编辑: list

        <activity
        android:name=".TransitionLandscape"
        android:configChanges="orientation"
        android:label="@string/app_name"
        android:launchMode="singleTask"
        android:screenOrientation="landscape"
        android:windowSoftInputMode="stateHidden">
    </activity>

实际上，我在 TransitionLandscape 之后调用的任何 Activity 都会导致应用退出。是内存问题吗？

最佳答案

您的应用在该 Intent 之后崩溃，因为收到配置更改。

12-10 21:08:23.520 543-600/? I/InputReader: Reconfiguring input devices.  changes=0x00000004
    Device reconfigured: id=2, name='elan-touchscreen', size 800x1280, orientation 0, mode 1, display id 0
12-10 21:08:23.520 543-1012/? I/ActivityManager: Config changes=480 {1.0 310mcc170mnc en_US ldltr sw600dp w600dp h880dp 213dpi
lrg port finger -keyb/v/h -nav/h s.11}
    12-10 21:08:23.540 961-961/? I/PCKeyboard: onConfigurationChanged()
12-10 21:08:23.740 4801-4801/com.assistek.ediary D/Time calculation:: Destroy: class
com.assistek.ediary.TransitionLandscape

你能试试吗

android:configChanges="orientation|screenSize|keyboardHidden" />

还有其他方法可以处理配置更改 你可以查看这个link
