我知道这个问题已经问了很多次在这个论坛。但我仍然无法得到解决方案。 基本上在我的应用程序,我打电话内置相机意图,捕获图像,并在ImageView中显示位图并将其存储在SD卡中。现在,我在我的文件夹中获得的图像尺寸很小,就像缩略图一样。从相机捕获的图像是不是全尺寸存储
我的代码是
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(Intent.createChooser(cameraIntent, "Select picture"), CAMERA_REQUEST);
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
try {
if (requestCode == CAMERA_REQUEST) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
if (photo != null) {
imageView.setImageBitmap(photo);
}
// Image name
final ContentResolver cr = getContentResolver();
final String[] p1 = new String[] { MediaStore.Images.ImageColumns._ID,
MediaStore.Images.ImageColumns.DATE_TAKEN };
Cursor c1 = cr.query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, p1, null,
null, p1[1] + " DESC");
if (c1.moveToFirst()) {
String uristringpic = "content://media/external/images/media/" + c1.getInt(0);
Uri newuri = Uri.parse(uristringpic);
String snapName = getRealPathFromURI(newuri);
Uri u = Uri.parse(snapName);
File f = new File("" + u);
String fileName = f.getName();
editTextPhoto.setText(fileName);
checkSelectedItem = true;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
photo.compress(CompressFormat.PNG, 0 /* ignored for PNG */, bos);
byte[] bitmapdata = bos.toByteArray();
// Storing Image in new folder
StoreByteImage(mContext, bitmapdata, 100, fileName);
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
Uri.parse("file://" + Environment.getExternalStorageDirectory())));
// Delete the image from the Gallery
getContentResolver().delete(newuri, null, null);
}
c1.close();
}
} catch (NullPointerException e) {
System.out.println("Error in creating Image." + e);
} catch (Exception e) {
System.out.println("Error in creating Image." + e);
}
System.out.println("*** End of onActivityResult() ***");
}
public String getRealPathFromURI(Uri contentUri) {
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
public boolean StoreByteImage(Context pContext, byte[] pImageData,
int pQuality, String pExpName) {
String nameFile = pExpName;
// File mediaFile = null;
File sdImageMainDirectory = new File(
Environment.getExternalStorageDirectory() + "/pix/images");
FileOutputStream fileOutputStream = null;
try {
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 0;
Bitmap myImage = BitmapFactory.decodeByteArray(pImageData, 0,
pImageData.length, options);
if (!sdImageMainDirectory.exists()) {
sdImageMainDirectory.mkdirs();
}
sdImageMainDirectory = new File(sdImageMainDirectory, nameFile);
sdImageMainDirectory.createNewFile();
fileOutputStream = new FileOutputStream(
sdImageMainDirectory.toString());
BufferedOutputStream bos = new BufferedOutputStream(
fileOutputStream);
myImage.compress(CompressFormat.JPEG, pQuality, bos);
bos.flush();
bos.close();
} catch (FileNotFoundException e) {
Toast.makeText(pContext, e.getMessage(), Toast.LENGTH_LONG).show();
e.printStackTrace();
} catch (IOException e) {
Toast.makeText(pContext, e.getMessage(), Toast.LENGTH_LONG).show();
e.printStackTrace();
}
和ImageView的main.xml中是
<ImageView
android:id="@+id/test_image"
android:src="@drawable/gray_pic"
android:layout_width="180dp"
android:layout_height="140dp"
android:layout_below="@id/edit2"
android:layout_toRightOf="@id/edit3"
android:layout_alignParentRight="true"
android:layout_marginTop="7dp"
android:layout_marginBottom="5dp"
android:layout_marginLeft="7dp"
android:layout_marginRight="7dp"
/>
有了这个代码让我的文件夹中的小尺寸的ImageView和形象店。 如果我添加intent.putExtra,那么在ImageView中既不会捕获图像,也不会在新文件夹中创建图像。
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
String path = Environment.getExternalStorageDirectory().getAbsolutePath();
path += "/myFolder/myPicture.jpg";
File file = new File(path);
Uri outputFileUri = Uri.fromFile(file);
cameraIntent.putExtra("output", outputFileUri);
startActivityForResult(Intent.createChooser(cameraIntent, "Select Picture"), CAMERA_REQUEST);
}
不知道我在哪里来袭.. 任何关于这帮助将不胜感激。
感谢ABHI的答复。但我仍然得到相同的结果。该文件夹本身没有创建。我的outputFileUri在上面的代码中是否正确?而且还没有在imageview中获取图像缩略图...其实我正在使用StoreByteImage()方法来创建文件夹和存储图像。该方法的任何更改要完成? – Shrikant 2012-01-28 11:47:22
看到我编辑的问题,试试那种方式 – Abhi 2012-01-28 12:22:29
我会试一试,让你知道.. – Shrikant 2012-01-28 13:51:44
