###实现代码

``` java

public class MainActivity extends ActionBarActivity {

    public static final int NONE = 0;

    public static final int PHOTOHRAPH = 1;// 拍照

    public static final int PHOTOZOOM = 2; // 缩放

    public static final int PHOTORESOULT = 3;// 结果

    public static final String IMAGE_UNSPECIFIED = "image/*";

    ImageView imageView = null;

    Button button0 = null;

    Button button1 = null;

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        imageView = (ImageView) findViewById(R.id.imageID);

        button0 = (Button) findViewById(R.id.btn_01);

        button1 = (Button) findViewById(R.id.btn_02);

        button0.setOnClickListener(new View.OnClickListener(){

            @Override

            public void onClick(View v) {

                Intent intent = new Intent(Intent.ACTION_PICK, null);

                intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, IMAGE_UNSPECIFIED);

                startActivityForResult(intent, PHOTOZOOM);

            }

        });

        button1.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

                intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "temp.jpg")));

                startActivityForResult(intent, PHOTOHRAPH);

            }

        });

    }

    @Override

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (resultCode == NONE)

            return;

        // 拍照

        if (requestCode == PHOTOHRAPH) {

            //设置文件保存路径这里放在跟目录下

            File picture = new File(Environment.getExternalStorageDirectory() + "/temp.jpg");

            startPhotoZoom(Uri.fromFile(picture));

        }

        if (data == null)

            return;

        // 读取相册缩放图片

        if (requestCode == PHOTOZOOM) {

            startPhotoZoom(data.getData());

        }

        // 处理结果

        if (requestCode == PHOTORESOULT) {

            Bundle extras = data.getExtras();

            if (extras != null) {

                Bitmap photo = extras.getParcelable("data");

                ByteArrayOutputStream stream = new ByteArrayOutputStream();

                photo.compress(Bitmap.CompressFormat.JPEG, 75, stream);// (0 - 100)压缩文件

                imageView.setImageBitmap(photo);

            }

        }

        super.onActivityResult(requestCode, resultCode, data);

    }

    public void startPhotoZoom(Uri uri) {

        Intent intent = new Intent("com.android.camera.action.CROP");

        intent.setDataAndType(uri, IMAGE_UNSPECIFIED);

        intent.putExtra("crop", "true");

        // aspectX aspectY 是宽高的比例

        intent.putExtra("aspectX", 1);

        intent.putExtra("aspectY", 1);

        // outputX outputY 是裁剪图片宽高

        intent.putExtra("outputX", 100);

        intent.putExtra("outputY", 100);

        intent.putExtra("return-data", true);

        startActivityForResult(intent, PHOTORESOULT);

    }
