捕捉图像，然后使用 activity 在另一个布局中显示

Question

我想通过在 FirstActivity 中点击按钮Capture捕捉图像，然后使用SecondActivity在activity_second(layout)中显示出来。如何实现？
代码部分：
FirstActivity

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_first);

    Button take_photo = (Button) findViewById(R.id.btn_capture);
    take_photo.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                startActivity(i);
            }
        });
}

Layout activity_first

> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <Button
        android:id="@+id/btn_capture"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="21dp"
        android:text="Capture" />
</RelativeLayout>

SecondActivity

> public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);

        ImageView view = (ImageView) findViewById(R.id.view_photo);
    }

activity_second

> <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/view_photo"
        android:layout_width="260dp"
        android:layout_height="374dp" />
</LinearLayout>

Answer 1

使用 startActivityForResult() 代替 startActivity()

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);
    Bitmap thumbnail = null;
    if (requestCode == CAMERA_PIC_REQUEST) {
        if (resultCode == RESULT_OK) {
            thumbnail = (Bitmap) data.getExtras().get("data");
            Intent i = new Intent(this, NextActivity.class);
            i.putExtra("name", thumbnail);
            startActivity(i);
        }
    }
}

然后在另一个 activity 中使用

 protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
     //     intialize the image view 
    Bitmap bitmap  = getIntent().getExtras().getParcelable("data");
//set the image here.
}
