Android手机相册和拍照实现

     具体类代码如下：

public class Register2Fragment extends Fragment {

	private Button mNextButton;
	private Button mBackButton;
	private LinearLayout mFooterLayout;
	private LinearLayout mBodyLayout;
	private Button photo;
	private Button camera;
	private ImageView image;
	private String local_path = Environment.getExternalStorageDirectory()+"/";//图片根路径
	private String path;//图片存储路径
//	private ProgressBar pb;  
//	private TextView upload;
	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/*";  
	
	@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup parent,
			Bundle savedInstanceState) {
		View v = inflater.inflate(R.layout.fragment_register2, parent, false);
		RegListener2 listener = new RegListener2();
		photo = (Button) v.findViewById(R.id.register_album_chosen);// 相册
		photo.setOnClickListener(listener);

		camera = (Button) v.findViewById(R.id.register_kacha);// 拍照
		camera.setOnClickListener(listener);

		image = (ImageView) v.findViewById(R.id.reigster2_image);// 显示照片

		mBackButton = (Button) v.findViewById(R.id.register1_3_back);// 返回
		mBackButton.setOnClickListener(listener);

		mNextButton = (Button) v.findViewById(R.id.register1_3_next);// 点击“下一步”按钮
		mNextButton.setOnClickListener(listener);
		
//		pb = (ProgressBar) v.findViewById(R.id.uploadbar);//进度条
//		upload = (TextView) v.findViewById(R.id.uploadtext);

		LinearLayout mNavBackButton = (LinearLayout) v.findViewById(R.id.register2_nav_back);
		mNavBackButton.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				RegisterActivity.simulateKey(KeyEvent.KEYCODE_BACK);
			}
		});

		TextView mSkipButton = (TextView) v.findViewById(R.id.register2_skip);

		mSkipButton.setOnClickListener(listener);
		
		mFooterLayout=(LinearLayout) v.findViewById(R.id.register2_footer);//更换布局
		
		mBodyLayout=(LinearLayout) v.findViewById(R.id.register2_body);
		
		return v;
	}
