但是,当我尝试设置图像的壁纸(参考类ViewPhotoActivity.java)时,我得到以下错误
Run Code Online (Sandbox Code Playgroud)android.content.ActivityNotFoundException:无法找到显式活动类{com.android.camera/com.android.camera.CropImage}; 你有没有在AndroidManifest.xml中声明这个活动？
我认为以下代码导致了问题
final Intent intent = new Intent("com.android.camera.action.CROP");
intent.setClassName("com.android.camera", "com.android.camera.CropImage");
intent.setData(Uri.fromFile(mFile));
intent.putExtra("outputX", width);
intent.putExtra("outputY", height);
intent.putExtra("aspectX", width);
intent.putExtra("aspectY", height);
intent.putExtra("scale", true);
intent.putExtra("noFaceDetection", true);
intent.putExtra("output", Uri.parse("file:/" + mFile.getAbsolutePath()));
startActivityForResult(intent, REQUEST_CROP_IMAGE);

请注意字符串中有一个单引号
我想用连字符符号拆分它,结果就是这样
[0] Average Sized
[1] Mega Church!
