使用Android使用Capture Image裁剪图像问题

Question

我从不同按钮使用相机功能Capture图像2次。捕获图像后，它转到Crop选项，用户可以裁剪图像。它也很好。

但是，现在的问题是当用户捕获第二张图像时，App会重定向到Crop图像并仅显示第一张图像而不是第二张图像。在将其设置为ImageView后，我也在删除图像。不知道出了什么问题？

请帮我解决这个问题。

我的代码：

Bitmap bm_PhotoProof = null;
    Bitmap bm_AddressProof = null;

    private static final String TEMP_PHOTO_FILE = "tmp_ihis.jpg";
    private static final int REQ_CODE_PICK_IMAGE_PHOTOPROOF = 0;
    private static final int REQ_CODE_PICK_IMAGE_ADDRESSPROOF = 1;
imgPhotoProof.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub

                Intent cameraIntent = new Intent(
                        android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, getTempUri());
                cameraIntent.putExtra("outputFormat",
                        Bitmap.CompressFormat.JPEG.toString());
                startActivityForResult(cameraIntent,
                        REQ_CODE_PICK_IMAGE_PHOTOPROOF);
            }
        });

        imgAddressProof.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub

                Intent cameraIntent = new Intent(
                        android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, getTempUri());
                cameraIntent.putExtra("outputFormat",
                        Bitmap.CompressFormat.JPEG.toString());
                startActivityForResult(cameraIntent,
                        REQ_CODE_PICK_IMAGE_ADDRESSPROOF);
            }
        });
private Uri getTempUri() {
        return Uri.fromFile(getTempFile());
    }

    private File getTempFile() {

        File f = new File(Environment.getExternalStorageDirectory(),
                TEMP_PHOTO_FILE);
        try {
            f.createNewFile();
        } catch (IOException e) {
            Log.e("getTempFile()->", e.getMessage().toString());
        }

        return f;
    }

    public void cropCapturedImage(Uri picUri, String Type) {

        Intent cropIntent = new Intent("com.android.camera.action.CROP");
        cropIntent.setDataAndType(picUri, "image/*");
        cropIntent.putExtra("crop", "true");
        cropIntent.putExtra("aspectX", 0);
        cropIntent.putExtra("aspectY", 0);
        cropIntent.putExtra("outputX", 256);
        cropIntent.putExtra("outputY", 256);
        cropIntent.putExtra("return-data", true);

        if (Type.equals("Photo")) {
            startActivityForResult(cropIntent, 5);
        } else {
            startActivityForResult(cropIntent, 6);
        }
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (resultCode == Activity.RESULT_OK) {
            if (requestCode == REQ_CODE_PICK_IMAGE_PHOTOPROOF) {

                File tempFile = getTempFile();
                cropCapturedImage(Uri.fromFile(tempFile), "Photo");

            } else if (requestCode == REQ_CODE_PICK_IMAGE_ADDRESSPROOF) {

                File tempFile = getTempFile();

                    }

我已经解决了这个问题。

之前，我正在删除文件。现在，我已经清除了缓存，它解决了我的问题。

File tempFile = getTempFile();
      if (tempFile.exists()) {
      tempFile.delete();
}

以

File tempFile = getTempFile();
File cacheDir = getActivity().getCacheDir();
File file = new File(cacheDir, getTempFile().toString());
file.delete();
