Как добавить изображение с камеры в ImageView в Android?

Question

В моем классе Java-кода есть кнопка, которая позволяет пользователю получить доступ к камере, сделать снимок, а затем это изображение должно быть добавлено в ImageView.
Мне не удалось достичь этой функциональности.

Вот мой Java-код:

package com.example.vikingpianomovers;

Answer 1

использование этого

@Override 
//result of dispatchTakePictureIntent 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) { 
    mImageView.setImageBitmap(new BitmapDrawable(getBaseContext(), 
         getPath(data.getData(),getBaseContext()))); 
    } 
} 

добавить этот метод тоже

public String getPath(Uri uri,Context c) { 
    String[] projection = { MediaStore.Images.Media.DATA }; 
    Cursor cursor = c.getContentResolver().query(uri, projection, null, null, null); 
    if (cursor == null) 
     return null; 
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); 
    cursor.moveToFirst(); 
    String s=cursor.getString(column_index); 
    cursor.close(); 
    return s; 
}
