Android相机应用程序。两项活动

Question

我正在尝试开发Android应用程序。我正在学习Android，所以我去了。 我的用法与此类似：http://www.tutorialspoint.com/android/android_camera.htm; 除了我有两个活动..一个叫做Report.java，另一个叫做Form.java。 在Report.java中，我有一个按钮，当我点击按钮时，我想打开相机并拍照。拍完照片之后，我想开始第二个活动（Form.java）和我的图像保存在ImageView中。 我怎样才能做到这一点？提前谢谢。

Report.java

package com.example.harta;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

public class Report extends Activity implements View.OnClickListener{
    ImageView iv;
    Button report;
    final static int cameraData = 0;
    Bitmap bmp;
    Intent i;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.report);
        initialize();
        report.setOnClickListener(this);
    }



    private void initialize() {
        // TODO Auto-generated method stub
        report = (Button) findViewById(R.id.bReport);
    }

    public void onClick(View v) {
        // TODO Auto-generated method stub
        switch(v.getId()){
           case R.id.bReport:
               i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
               startActivityForResult(i, cameraData);
               break;
        }   
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);
        if(resultCode == RESULT_OK){
            Bundle extras = data.getExtras();
            bmp = (Bitmap) extras.get("data");
            Intent i = new Intent(Report.this, Formular.class);
            startActivity(i);
        }
    }
}

Form.java
