java - 我在 android 中使用 getParcelable 检索位图文件时遇到错误

Question

我试图获取已传递到 Intent 中的位图文件，但 getParcelable() 方法每次都返回 null。

以下是我的 java 代码，我将在其中发送我的位图图像:

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = ImageSharing.getOutputMediaFileUri(StaticMembers.MEDIA_TYPE_IMAGE, false);

List<Intent> cameraIntents = new ArrayList<Intent>();
PackageManager packageManager = getActivity().getPackageManager();
List<ResolveInfo> listCam = packageManager.queryIntentActivities(cameraIntent, 0);
for (ResolveInfo res : listCam) {
    String packageName = res.activityInfo.packageName;
    Intent intent = new Intent(cameraIntent);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
    intent.setPackage(packageName);
    intent.putExtra("return-data", true);
    cameraIntents.add(intent);
}

Intent galleryIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
galleryIntent.setType(StaticMembers.IMAGE_TYPE);

Intent chooserIntent;
if (null == newmobilelangs && null == newmobilelangs.getCommon().getCompleteAction()) {
    chooserIntent = Intent.createChooser(galleryIntent, "Complete action using");
} else {
    chooserIntent = Intent.createChooser(galleryIntent, newmobilelangs.getCommon()
            .getCompleteAction());
}
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[cameraIntents.size()]));
startActivityForResult(chooserIntent, 1);

以下是我尝试检索图像的 java 代码:

Bitmap profilePic;
String fileName, filePath;
Log.i("what is data?", data.toString());
Bundle extras = data.getExtras();
profilePic = extras.getParcelable("data");

上面代码的最后一行出现问题:

profilePic = extras.getParcelable("data");

以下是我来自SettingFragment.java的onActivityResult()方法

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    try {
        if (resultCode == Activity.RESULT_OK) {
            if (requestCode == 1) {
                boolean isCamera;
                isCamera = ((data == null) || (data.hasExtra(MediaStore.EXTRA_OUTPUT)));

                Intent intent = new Intent("com.android.camera.action.CROP");
                if (isCamera) {
                    intent.setDataAndType(fileUri, StaticMembers.IMAGE_TYPE);
                } else {
                    intent.setDataAndType(data.getData(), StaticMembers.IMAGE_TYPE);
                }

                intent.putExtra("crop", "true");
                intent.putExtra("aspectX", 1);
                intent.putExtra("aspectY", 1);
                // intent.putExtra("outputX", 150);
                // intent.putExtra("outputY", 150);
                intent.putExtra("scale", true);
                intent.putExtra("noFaceDetection", true);
                intent.putExtra("return-data", true);
                tempFileURI = ImageSharing.getOutputMediaFileUri(StaticMembers.MEDIA_TYPE_IMAGE, false);
                Log.i("Yes!", tempFileURI.toString());
                intent.putExtra(MediaStore.EXTRA_OUTPUT, tempFileURI);
                startActivityForResult(intent, 2);
            } else if (requestCode == 2) {
                Bitmap profilePic;
                String fileName, filePath;
                Log.i("what is data?", data.toString());
                Bundle extras = data.getExtras();
                profilePic = extras.getParcelable("data");

Answer 1

如下:

Intent { dat=file:///storage/sdcard0/CometChat Images/IMG20150914111228.jpg typ=image/jpeg }

获取响应中图像的 URI。因此从 URI 获取 Bitmap 如下:

Uri imageUri = data.getData();
profilePic = MediaStore.Images.Media.getBitmap(this.getContentResolver(),imageUri);
