嗨，我想要一個應用程序，從相機捕獲圖像以顯示它在anothor活動並應用一些效果，但我無法發送捕獲的圖像到第二個活動。請幫幫我。 MainActivity代碼：傳輸從相機捕獲的圖像並將其顯示在另一個活動中？
package com.example.dias.prendrephoto;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
Button btn;
Bitmap bmp;
private static final int CAMERA_REQUEST = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn = (Button) findViewById(R.id.btn);
}
public void PrendrePhoto(View view) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
//Bitmap mphoto = (Bitmap) data.getExtras().get("data");
Bundle bundle = new Bundle();
bundle = data.getExtras();
bmp = (Bitmap) bundle.get("data");
Intent i= new Intent(getApplicationContext(),Main2Activity.class);
i.putExtra("monimage",bmp);
startActivity(i);
}
}
}
Main2Activity代碼：

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);

Bundle bundle = getIntent().getExtras();
if (bundle != null) {
image = bundle.getParcelable("monimage");
imgV.setImageBitmap(image);
}

}
