以下是跳转到选择图片界面：
Intent intent = new Intent(this, SelectPictureActivity.class); intent.putExtra("selected", selected); startActivityForResult(intent, 0); 以下是当回到当前界面的时候拿出图片路径：
@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (resultCode == RESULT_OK && requestCode == 0) { if (data == null) { return; } CommonDialog commonDialog = new CommonDialog(this, "正在提交数据..."); commonDialog.show(); ArrayList<String> temp = (ArrayList<String>) data.getSerializableExtra(SelectPictureActivity.INTENT_SELECTED_PICTURE); for (String path : temp) { //遍历拿到图片途径,把数据加载到集合里面 RecordEntity entity = new RecordEntity(); entity.setType(1); entity.setWhoTake("王大锤"); entity.setTakeTime(TimeFormartUtils.getCurrentTimeSeconds()); entity.setPath(path); entity.setNorthLatitude(String.valueOf(location.getLatitude())); entity.setEastLongtudtude(String.valueOf(location.getLongitude())); recordEntitiesNew.add(entity); recordEntitiesAdapter.add(entity); visorListAdapter.setData(recordEntitiesAdapter); } commonDialog.dismiss(); }
