Java 如何在onActivityResult中设置不同的请求代码？
我有一个应用程序，可以从gallery或camera中选择图片，并将其放在imageview上。问题是我不能为同一个OnActivityResult设置两个不同的请求代码。 相机捕捉可以工作，但gallery不能。我明白了： java.lang.RuntimeException:未能传递结果ResultInfo{who=null，request=1，result=-1，data=Intent{dat=content://media/external/images/media/272 flg=0x1}}到活动{com.parse.starter/com.parse.starter.reportar}:java.lang.NullPointerException:uriString 位于android.app.ActivityThread.deliverResults（ActivityThread.java:3649） 谁能帮帮我吗？？这是我的密码：Java 如何在onActivityResult中设置不同的请求代码？,java,android,android-studio,Java,Android,Android Studio,我有一个应用程序，可以从gallery或camera中选择图片，并将其放在imageview上。问题是我不能为同一个OnActivityResult设置两个不同的请求代码。 相机捕捉可以工作，但gallery不能。我明白了： java.lang.RuntimeException:未能传递结果ResultInfo{who=null，request=1，result=-1，data=Intent{dat=content://media/external/images/media/272 flg=0x
