安卓手机如何调用拍照上传和相册 来上传图片 用代码 帮我实现一下

您好，以下是调用安卓手机相机和相册上传图片的代码示例：

调用相机拍照并上传：

private static final int REQUEST_CODE_CAMERA = 1;
private File mTempFile;

// 调用相机拍照
private void takePhoto() {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (intent.resolveActivity(getPackageManager()) != null) {
        try {
            mTempFile = createImageFile();
        } catch (IOException e) {
            e.printStackTrace();
        }
        if (mTempFile != null) {
            Uri photoUri = FileProvider.getUriForFile(this, getPackageName() + ".fileprovider", mTempFile);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);
            startActivityForResult(intent, REQUEST_CODE_CAMERA);
        }
    }
}

// 创建临时文件
private File createImageFile() throws IOException {
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    return File.createTempFile(imageFileName, ".jpg", storageDir);
}

// 上传图片
private void uploadImage(File file) {
    // TODO: 上传图片的代码
}

// 处理拍照结果
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CODE_CAMERA && resultCode == RESULT_OK) {
        if (mTempFile != null) {
            uploadImage(mTempFile);
        }
    }
}

调用相册选择照片并上传：

private static final int REQUEST_CODE_ALBUM = 2;

// 调用相册选择照片
private void choosePhoto() {
    Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(intent, REQUEST_CODE_ALBUM);
}

// 处理选择照片结果
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CODE_ALBUM && resultCode == RESULT_OK) {
        if (data != null) {
            Uri photoUri = data.getData();
            String[] filePathColumns = {MediaStore.Images.Media.DATA};
            Cursor cursor = getContentResolver().query(photoUri, filePathColumns, null, null, null);
            if (cursor != null && cursor.moveToFirst()) {
                int columnIndex = cursor.getColumnIndex(filePathColumns[0]);
                String imagePath = cursor.getString(columnIndex);
                cursor.close();
                File file = new File(imagePath);
                uploadImage(file);
            }
        }
    }
}

希望能对您有所帮助。
