我正在尝试按下我的应用程序中的按钮打开内置的图库应用程序.
我正在试用Android 2.3及以上的手机.我拥有的手机/平板电脑
三星S(Android 2.3.5)
LG手机(Android 2.3.3)
Nexus One(Android 2.3.6)
Android平板电脑(Android 4.0.3)
Galaxy Nexus(Android 4.3)
我尝试了以下方法:
Intent intent = new Intent(Intent.ACTION_VIEW, null); intent.setType("image/*"); startActivity(intent);
上面的代码在Android平板电脑(4.0.3)和我的Nexus手机上运行良好..但如果在任何低于3.0的手机上运行相同的应用程序(给我错误)

所以我尝试了以下内容:
Intent intent1= new Intent("android.intent.action.MAIN", null); intent1.addCategory("android.intent.category.APP_GALLERY"); Intent intent2 = Intent.createChooser(intent1, "Gallery"); startActivity(intent2);
再次,这适用于高于/等于4.0版本的手机.在4.0以下的手机上,它通过说:
"No application can perform this action"
有人可以帮助我从我的应用程序按下按钮打开图库吗?
我想通了……
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse( "content://media/internal/images/media")); startActivity(intent);
这条代码刚刚打开了画廊,没有任何问题.可以让它适用于所有版本!
想把它作为想要在所有版本上打开图库的人的答案.
多谢你们!
