推荐答案

在你的活动（称为 YourActivity ）

public static int TAKE_IMAGE = 111;
Uri mCapturedImageURI;

某处调用摄像头！

Somewhere call the camera!

try {
    String fileName = "temp.jpg";
    ContentValues values = new ContentValues();
    values.put(MediaStore.Images.Media.TITLE, fileName);
    mCapturedImageURI = getContentResolver()
            .insert(
                    MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                    values);
    Intent intent = new Intent(
            MediaStore.ACTION_IMAGE_CAPTURE);
    intent.putExtra(MediaStore.EXTRA_OUTPUT,
            mCapturedImageURI);
    startActivityForResult(intent, TAKE_IMAGE);
} catch (Exception e) {
    Log.e("", "", e);
}

现在的活动结果（公告 capturedImageFilePath ）

Now in the Activity result (notice capturedImageFilePath)

protected void onActivityResult(int requestCode, int resultCode,
        Intent intent) {
    if ((requestCode == YourActivity.TAKE_IMAGE)
            && (resultCode == RESULT_OK)) {
        mode = MODE_VIEWER;
        String[] projection = { MediaStore.Images.Media.DATA };
        Cursor cursor = managedQuery(mCapturedImageURI, projection, null,
                null, null);
        int column_index_data = cursor
                .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();

        //THIS IS WHAT YOU WANT!
        String capturedImageFilePath = cursor.getString(column_index_data);

        bitmap = BitmapFactory.decodeFile(capturedImageFilePath);
    }
}
