Question

我正在制作一个Android应用程序，我想要使用相机。我正确地实现了代码但是我面临的问题是我捕获的图像被保存了两次，一个是水平的，另一个是垂直的。这是一个奇怪的问题，我无法弄清楚。以下是我正在使用的代码。

AlertDialog.Builder builder = new AlertDialog.Builder(
                FaceconActivity.this);
        builder.setTitle("Share a Photo");
        builder.setItems(items, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int item) {
                if (item == 0) {
                    values = new ContentValues();
                    values.put(MediaStore.Images.Media.TITLE, "New Picture");
                    values.put(MediaStore.Images.Media.DESCRIPTION,
                            "From your Camera");
                    imageUri = getContentResolver().insert(
                            MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                            values);
                    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                    intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
                    startActivityForResult(intent, PICTURE_RESULT);
                } else if (item == 1) {
                    try {
                        Intent intent = new Intent();
                        intent.setType("image/*");
                        intent.setAction(Intent.ACTION_GET_CONTENT);
                        startActivityForResult(
                                Intent.createChooser(intent, "Select Picture"),
                                PICK_IMAGE);
                    } catch (Exception e) {
                        Toast.makeText(getApplicationContext(), e.getMessage(),
                                Toast.LENGTH_LONG).show();
                        Log.e(e.getClass().getName(), e.getMessage(), e);
                    }
                }
            }
        });
        builder.show();

和

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        switch (requestCode) {
        case PICK_IMAGE:
            if (resultCode == Activity.RESULT_OK) {
                Uri selectedImageUri = data.getData();
                try {
                    // OI FILE Manager
                    String filemanagerstring = selectedImageUri.getPath();
                    // MEDIA GALLERY
                    String selectedImagePath = getPath(selectedImageUri);
                    if (selectedImagePath != null) {
                        filePath = selectedImagePath;
                    } else if (filemanagerstring != null) {
                        filePath = filemanagerstring;
                    } else {
                        Toast.makeText(getApplicationContext(), "Unknown path",
                                Toast.LENGTH_LONG).show();
                        Log.e("Bitmap", "Unknown path");
                    }

                    if (filePath != null) {
                        decodeFile(filePath);
                    } else {
                        bitmap = null;
                    }
                } catch (Exception e) {
                    Toast.makeText(getApplicationContext(), "Internal error",
                            Toast.LENGTH_LONG).show();
                    Log.e(e.getClass().getName(), e.getMessage(), e);
                }
            }
            break;
        case PICTURE_RESULT:
            if (requestCode == PICTURE_RESULT)
                if (resultCode == Activity.RESULT_OK) {
                    try {
                        thumbnail = MediaStore.Images.Media.getBitmap(
                                getContentResolver(), imageUri);
                        imageurl = getRealPathFromURI(imageUri);
                        decodeFile(imageurl);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }

                }
        }
    }

任何人都可以帮助我吗？ -Thanks in advace

in item == o请使用以下工作代码:::

Calendar cal = Calendar.getInstance();
File file = new File(Environment.getExternalStorageDirectory(),(cal.getTimeInMillis()+".jpg"));
if(!file.exists()){
    try {
        file.createNewFile();
    } catch (IOException e) {
    // TODO Auto-generated catch block
        e.printStackTrace();
    }
}else{
    file.delete();
    try {
        file.createNewFile();
    } catch (IOException e) {
    // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
imageUri = Uri.fromFile(file);
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(i, PICTURE_RESULT);

您也可以根据需要更改图片名称
