如何解决Android studio：如何在我的第二个 Activity 中查看通过 Intent 方法携带的信息？？

大家好，我是 androID 开发的新手，我发现 recyclervIEw 很混乱。我目前正在尝试将一项活动的信息传递给另一项活动，但在我的第二项活动中，仅显示 cardvIEw。任何人都可以请帮我吗？非常感谢！

我的第二个活动

public class ChosenExerciseActivity extends AppCompatActivity {
    TextVIEw exercise_name,exercise_description;
    ImageVIEw exercise_image;

    @OverrIDe
    protected voID onCreate(Bundle savedInstanceStatE) {
        super.onCreate(savedInstanceStatE);
        setContentVIEw(R.layout.activity_chosen_exercisE);

        exercise_name = findVIEwByID(R.ID.SELEcted_Name);
        exercise_description = findVIEwByID(R.ID.SELEcted_description);
        exercise_image = findVIEwByID(R.ID.SELEcted_imagE);



        Intent intent = geTintent();
        exercise_name.setText(intent.getStringExtra("SELEcted_name"));
        exercise_description.setText(intent.getStringExtra("SELEcted_description"));
        exercise_image.setimageresource(intent.getIntextra("SELEcted_image",0));




        //System.out.println(exercise_name.getText().toString());




    }
} 

我的适配器类

/**
 * Class responsible for
 */
public class ExerciseAdapter extends RecyclerVIEw.Adapter<ExerciseAdapter.ExerciseVIEwHolder> {

    private ArrayList<Exercise> exercisesArray = new ArrayList<>();
    Context context;


    public ExerciseAdapter(ArrayList<Exercise> exercisesArray,Context context){
        this.exercisesArray = exercisesArray;
        this.context = context;
    } //constructor

    @NonNull
    @OverrIDe
    public ExerciseVIEwHolder onCreateVIEwHolder(@NonNull VIEwGroup parent,int i) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.homepage_design,parent,falsE); //inflate the layout xml file and display it on the parent
        return new ExerciseVIEwHolder(vIEw);
    }

    @OverrIDe
    public voID onBindVIEwHolder(@NonNull ExerciseVIEwHolder holder,int position) {

        holder.bind(exercisesArray.get(position)); //bind method comes from the ProjectVIEwHolder inner class
        holder.itemVIEw.setonClickListener(new VIEw.onClickListener() {
            @OverrIDe
            public voID onClick(VIEw v) {
                Intent intent = new Intent(v.getContext(),ChosenExerciseActivity.class);
                intent.putExtra( "text_vIEw_exercise_name",exercisesArray.get(position).getExercise_name());
                intent.putExtra( "text_vIEw_exercise_description",exercisesArray.get(position).getExercise_description());
                intent.putExtra( "text_vIEw_exercise_description",exercisesArray.get(position).getExercise_image());
                v.getContext().startActivity(intent); //you cAnnot start an activity without a context(this) so that you a Context object which will refer to the activity you wish to retrIEve the information
            }
        });
    }

    @OverrIDe
    public int getItemCount() {

        return exercisesArray.size();
    }

    class ExerciseVIEwHolder extends RecyclerVIEw.VIEwHolder {

        TextVIEw text_vIEw_exercise_name,text_vIEw_exercise_description;
        ImageVIEw image_vIEw_exercise_image;
        CardVIEw card_vIEw_exercises;

        public ExerciseVIEwHolder(@NonNull VIEw itemVIEw){
            super(itemVIEw);

            //itemVIEw.setonClickListener(this); //set the screen to capture the users click
            card_vIEw_exercises = itemVIEw.findVIEwByID(R.ID.card_vIEw_parent);
            text_vIEw_exercise_name = itemVIEw.findVIEwByID(R.ID.text_vIEw_exercise_Name);
            text_vIEw_exercise_description = itemVIEw.findVIEwByID(R.ID.text_vIEw_exercise_description);
            image_vIEw_exercise_image = itemVIEw.findVIEwByID(R.ID.image_vIEw_exercise_imagE);

        }

        public voID bind(Exercise exercisE) {

            text_vIEw_exercise_name.setText(exercise.getExercise_name());
            text_vIEw_exercise_description.setText(exercise.getExercise_description());
            image_vIEw_exercise_image.setimageresource(exercise.getExercise_image());


        }


//        @OverrIDe
//        public voID onClick(VIEw v) {
//            int position = getAdapterposition();
//            Exercise chosenExercise = exercisesArray.get(position);
//
//        }
    }
} 

enter image description here

解决方法

Intent intent = new Intent(v.getContext(),ChosenExerciseActivity.class);
intent.putExtra( "SELEcted_name",exercisesArray.get(position).getExercise_name());
intent.putExtra( "SELEcted_description",exercisesArray.get(position).getExercise_description());
intent.putExtra( "SELEcted_image",exercisesArray.get(position).getExercise_image());
v.getContext().startActivity(intent);

public static int INTENT_EXERCISE_NAME = "INTENT_EXERCISE_NAME"

intent.putExtra(INTENT_EXERCISE_NAME,exercisesArray.get(position).getExercise_name());
