[英]Android:Problem in saving cropped image taken from camera
I am getting problem in saving a cropped image taken from camera at specified path in SD card. 我在将从相机拍摄的裁剪图像保存到SD卡中的指定路径时遇到问题。
code--> 代码->
public class PhotocropActivity extends Activity
{
/** Called when the activity is first created. */
private static final int SELECT_PICTURE = 1;
private static final int PICK_FROM_CAMERA = 2;
private Uri muri;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final CharSequence[] items = {"Capture New Image", "Upload from gallery"};
AlertDialog.Builder builder = new AlertDialog.Builder(PhotocropActivity.this);
builder.setTitle("Select Image");
builder.setItems(items, new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int item)
{
Intent intent = new Intent();
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 730);
intent.putExtra("aspectY", 1115);
intent.putExtra("outputX", 730);
intent.putExtra("outputY", 1115);
intent.putExtra(MediaStore.EXTRA_OUTPUT, getTempFile());
intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
if(item==0)
{
intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, PICK_FROM_CAMERA);
}
else if(item==1)
{
intent.setAction(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, SELECT_PICTURE);
}
}
private Uri getTempFile()
{
muri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(),"Image_" + String.Valueof(System.currentTimeMillis()) + ".jpg"));
return muri;
}
});
final AlertDialog alert = builder.create();
((Button) findViewById(R.id.button)).setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View view)
{
alert.show();
}
});
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode)
{
case PICK_FROM_CAMERA : if (resultCode == RESULT_OK)
{
String filePath= muri.getPath();
Toast.makeText(this, filePath, Toast.LENGTH_SHORT).show();
Bitmap selectedImage = BitmapFactory.decodeFile(filePath);
ImageView image = (ImageView)findViewById(R.id.selectedimage);
image.setImageBitmap(selectedImage);
}
break;
case SELECT_PICTURE : if (resultCode == RESULT_OK)
{
String filePath= muri.getPath();
Toast.makeText(this, filePath, Toast.LENGTH_SHORT).show();
Bitmap selectedImage = BitmapFactory.decodeFile(filePath);
ImageView image = (ImageView)findViewById(R.id.selectedimage);
image.setImageBitmap(selectedImage);
}
break;
default:
break;
}
}
}
here when I debug it then it is showing NULLPOINTEREXCEPTION at String filePath= muri.getPath(); 在这里,当我调试它时,它在字符串filePath = muri.getPath();中显示NULLPOINTEREXCEPTION。 in PICK_FROM_CAMERA. 在PICK_FROM_CAMERA中。 but it's showing muri value above in getTempFile(). 但它在getTempFile()中显示了上面的muri值。 Anyone help me.Fix the error in code?I m in great trouble. 有人帮我解决代码中的错误吗?

case PICK_FROM_CAMERA : if (resultCode == RESULT_OK)
{
ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, "title");
values.put(Images.Media.BUCKET_ID, "test");
values.put(Images.Media.DESCRIPTION, "test Image taken");
values.put(Images.Media.MIME_TYPE, "image/jpeg");
Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
Bitmap photo = (Bitmap) data.getExtras().get("data");
((ImageView)findViewById(R.id.selectedimage)).setImageBitmap(photo);
OutputStream outstream;
try {
outstream = getContentResolver().openOutputStream(uri);
photo.compress(Bitmap.CompressFormat.JPEG,100, outstream);
outstream.close();
} catch (FileNotFoundException e) {}
