我怎样才能捕捉Android的图像，并将它显示在画廊？ [英] How can I capture an image in Android and have it show up in the gallery?

问题描述

我在拍摄图像显示在画廊，但现在他们都没有，我想不出为什么。这是我的code：

I was capturing images before that were showing up in the gallery, but now they are not and I can't figure out why. Here is my code:

    	ContentValues values = new ContentValues();
	values.put(android.provider.MediaStore.Images.Media.IS_PRIVATE, false);
	String name = "ugc_" + String.valueOf(System.currentTimeMillis());
	values.put(android.provider.MediaStore.Images.Media.TITLE, name);
	imageURI = getContentResolver().insert(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

我也试过：     values​​.put（android.provider.MediaStore.Images.Media.IS_PRIVATE，0）; 还可以把在该值，但似乎没有现在的工作。

I've also tried: values.put(android.provider.MediaStore.Images.Media.IS_PRIVATE, 0); as well as leaving at that value, but nothing seems to work now.

推荐答案

非常喜欢不是pretty的，但是这是我怎么做。需要注意的是由于错误，将文件保存为1/16全分辨率（在每个维度1/4）。

Very much not pretty, but this is how I'm doing it. Note that due to a bug, the file saved is 1/16 the full resolution (1/4 in each dimension).

String SD_CARD_TEMP_DIR = Environment.getExternalStorageDirectory() + File.separator + "tmpPhoto.jpg";
Intent takePictureFromCameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
takePictureFromCameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, Uri.fromFile(new
    		File(SD_CARD_TEMP_DIR)));
startActivityForResult(takePictureFromCameraIntent, TAKE_PICTURE_WITH_CAMERA);

。 。

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    	super.onActivityResult(requestCode, resultCode, data);
    	// 	Picture taken from camera
    	if (requestCode == TAKE_PICTURE_WITH_CAMERA) {
    		if (resultCode == Activity.RESULT_OK) {

    			// http://code.google.com/p/android/issues/detail?id=1480
    			//Toast.makeText(AddPhotos.this, "" + data, Toast.LENGTH_SHORT).show();

    			// on activity return
    			File f = new File(SD_CARD_TEMP_DIR);
    			try {
    			    Uri capturedImage =
    			    	Uri.parse(android.provider.MediaStore.Images.Media.insertImage(getContentResolver(),
    			    			f.getAbsolutePath(), null, null));


    			    	Log.i("camera", "Selected image: " + capturedImage.toString());

    			    f.delete();
    			} catch (FileNotFoundException e) {
    			    // TODO Auto-generated catch block
    			    e.printStackTrace();
    			}


    		}
    		else {
    			Log.i("Camera", "Result code was " + resultCode);

    		}
    	}	
     }
