capturedImageUri will return path to captured Image not the actual Image..
另外,重要提示-如果您不需要使用全尺寸图像-
// cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mImageUri); Comment this line
Bitmap image = (Bitmap) data.getExtras().get("data");
要获得完整大小的位图,请使用以下代码 -
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
try
{
// place where to store camera taken picture
tempPhoto = createTemporaryFile("picture", ".png");
tempPhoto.delete();
}
catch(Exception e)
{
return ;
}
mImageUri = Uri.fromFile(tempPhoto);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mImageUri);
startActivityForResult(cameraIntent, 1);
private File createTemporaryFile(String part, String ext) throws Exception
{
// File to store image temperarily.
File tempDir= Environment.getExternalStorageDirectory();
tempDir=new File(tempDir.getAbsolutePath()+"/.temp/");
if(!tempDir.exists())
{
tempDir.mkdir();
}
return File.createTempFile(part, ext, tempDir);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
ContentResolver cr = getApplicationContext().getContentResolver();
try {
cr.notifyChange(mImageUri, null);
File imageFile = new File(tempPhoto.getAbsolutePath());
} catch (Exception e) {
e.printStackTrace();
}
Bitmap photo=null;
if (resultCode == 1) {
try {
photo = android.provider.MediaStore.Images.Media.getBitmap(cr, Uri.fromFile(tempPhoto));
imageView.setImageBitmap(photo);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
