实现拍照本地上传在GridView中显示

通过GridView的点击事件弹出一个PopupWindows窗体，在通过窗体中的按钮来调用系统拍照功能，和从sd卡中查询图片。PopupWindows窗体布局如下：

PopupWindows类代码如下：

public class PopupWindows extends PopupWindow {

		@SuppressWarnings("deprecation")
		public PopupWindows(Context mContext, View parent) {
			final View view = View.inflate(mContext, R.layout.photo_take, null);
			view.startAnimation(AnimationUtils.loadAnimation(mContext, R.anim.fade_ins));
			setWidth(LayoutParams.FILL_PARENT);
			setHeight(LayoutParams.FILL_PARENT);
			setBackgroundDrawable(new BitmapDrawable());
			setFocusable(true);
			setOutsideTouchable(true);
			setContentView(view);
			showAtLocation(parent, Gravity.BOTTOM, 0, 0);
			update();

			Button camera = (Button) view.findViewById(R.id.btn_take_photo);
			Button photo = (Button) view.findViewById(R.id.btn_pick_photo);
			Button cancel = (Button) view.findViewById(R.id.btn_cancel);
			
			view.setOnTouchListener(new OnTouchListener() {

				public boolean onTouch(View v, MotionEvent event) {

					int height = view.findViewById(R.id.pop_layout)
							.getTop();
					int y = (int) event.getY();
					if (event.getAction() == MotionEvent.ACTION_UP) {
						if (y < height) {
							dismiss();
						}
					}
					return true;
				}
			});
			
			camera.setOnClickListener(new OnClickListener() {//照相
				public void onClick(View v) {
					Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
					intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(sdcardTempFile));
					startActivityForResult(intent, TAKE_PICTURE);
					dismiss();
				}
			});
			photo.setOnClickListener(new OnClickListener() {//相册
				public void onClick(View v) {

					// 激活系统图库，选择一张图片
			        Intent intent = new Intent(Intent.ACTION_PICK);
			        intent.setType("image/*");
			        // 开启一个带有返回值的Activity，请求码为PHOTO_REQUEST_GALLERY
			        startActivityForResult(intent, RESULT_LOAD_IMAGE);
					dismiss();
				}
			});
			cancel.setOnClickListener(new OnClickListener() {
				public void onClick(View v) {
					dismiss();
				}
			});

		}
	}

主活动布局为：

主活动NewspaperRportAddActivity类如下：

public class NewspaperRportAddActivity extends MyBaseActivity  implements OnItemClickListener{
	private static final int IMG_MAX = 3;
    private static final int TAKE_PICTURE = 0;//拍照

这样就可以再GridView中显示自己手机相册中和自己拍的图片了。
