Question

我想添加一个包含当前位置的Google地图。我怎样才能做到这一点？我找到了这个代码，但位置是静态的。我该如何纠正？

      ExifInterface exif;

       try {

         exif = new ExifInterface(photoPath);

          } 

       catch (IOException e) {

        e.printStackTrace();

        exif = null;

          }

        if(exif!=null){

        orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);   

        }

      //get Bitmap
      Bitmpam bitm = ..... ;//uploaded file

       if(orientation==8){
           Matrix matrix = new Matrix();
           matrix.postRotate(270);
           bitm = Bitmap.createBitmap(bitm, 0, 0, bitm.getWidth(), bitm.getHeight(), matrix, true); 
                }
       if(orientation==6){
           Matrix matrix = new Matrix();
           matrix.postRotate(90);
           bitm = Bitmap.createBitmap(bitm, 0, 0, bitm.getWidth(), bitm.getHeight(),matrix,true);
                }
       if(orientation==3){
           Matrix matrix = new Matrix();
           matrix.postRotate(180);
           bitm = Bitmap.createBitmap(bitm, 0, 0, bitm.getWidth(), bitm.getHeight(),matrix,true);
           }

试试这个

    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(locationRequest);

    // **************************
    builder.setAlwaysShow(true); // this is the key ingredient

    // **************************
