android將值傳遞給另一個活動，但無法讀取

Question

我試圖將值傳遞給新的活動，但無法讀取新活動的值。

這裏是我的代碼，

Intent myIntent = new Intent(Photo2Activity.this, MainActivity.class); 

myIntent.putExtra("image1", image1); 
myIntent.putExtra("image2", image2); 
myIntent.putExtra("image3", image3); 

myIntent.putExtra("konteyner_no", _txt_konteyner_id.getText().toString()); 
myIntent.putExtra("mahalle", _txt_mahalle.getText().toString()); 
myIntent.putExtra("sokak", _txt_sokak.getText().toString()); 

myIntent.putExtra("konteyner_temizmi", _check_konteyner_temizmi.isChecked()); 
myIntent.putExtra("yaninda_cop_varmi", _check_yaninda_cop_varmi.isChecked()); 
myIntent.putExtra("aralarinda_cop_varmi", _check_aralarinda_cop_vardi.isChecked()); 
myIntent.putExtra("zamansiz_cop_varmi", _check_zamansiz_cop_vardi.isChecked()); 
myIntent.putExtra("cop_obekleri_vardi", _check_cop_obekleri_vardi.isChecked()); 

myIntent.putExtra("note", _txt_note.getText().toString()); 

startActivity(myIntent); 

我如何從新的活動（MainActivity）讀？

轉換位圖字節數組： -

Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher); 
ByteArrayOutputStream stream = new ByteArrayOutputStream(); 
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream); 
byte[] byteArray = stream.toByteArray(); 

通行證字節數組到意圖： - 從捆綁

Intent intent = new Intent(MainActivity.this, NextActivity.class); 
intent.putExtra("picture", byteArray); 
startActivity(intent); 

獲取字節數組，轉換成位圖圖像： -

Bundle extras = getIntent().getExtras(); 
byte[] byteArray = extras.getByteArray("picture"); 
Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length); 
ImageView image = (ImageView) findViewById(R.id.imageView1); 
image.setImageBitmap(bmp);
