android - 如何在点击不同的回收者 View 时启动不同的 Activity

Question

我有一个带有 GridLayoutManager 的 RecyclerView。单击每个项目我想开始不同的 Activity 。我试过了，但没有用。这是我的 DashboardAdapter 类

 public class DashboardAdapter extends RecyclerView.Adapter<DashboardAdapter.ViewHolder>{

private List<DashboardPojo> countries;
private int rowLayout;
private Context mContext;

public DashboardAdapter(List<DashboardPojo> countries, int rowLayout, Context context) {
    this.countries = countries;
    this.rowLayout = rowLayout;
    this.mContext = context;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
    View v = LayoutInflater.from(viewGroup.getContext()).inflate(rowLayout, viewGroup, false);
    return new ViewHolder(v);
}

@Override
public void onBindViewHolder(ViewHolder viewHolder, int i) {
    DashboardPojo country = countries.get(i);
    viewHolder.countryName.setText(country.name);
    viewHolder.countryImage.setImageResource(country.getImageResourceId(mContext));
}

@Override
public int getItemCount() {
    return countries == null ? 0 : countries.size();
}

public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
    public TextView countryName;
    public ImageView countryImage;

    public ViewHolder(View itemView) {
        super(itemView);
        mContext = itemView.getContext();
        itemView.setOnClickListener(this);
        countryName = (TextView) itemView.findViewById(R.id.countryName);
        countryImage = (ImageView)itemView.findViewById(R.id.countryImage);
    }
    @Override
    public void onClick(View v) {

        final Intent intent;
        if (getPosition() == 0){
            intent =  new Intent(mContext, TutorialActivity.class);
        } else if (getPosition() == 1){
            intent =  new Intent(mContext, JobsActivity.class);
        } else {
            intent =  new Intent(mContext, TutorialActivity.class);
        }
        mContext.startActivity(intent);
    }
}
 }

在我的 DashBoardActivity 中有

    mRecyclerView = (RecyclerView) findViewById(R.id.list);
    mLayoutManager = new GridLayoutManager(this, 2);
    mRecyclerView.setLayoutManager(mLayoutManager);
    mRecyclerView.setItemAnimator(new DefaultItemAnimator());
    mAdapter = new DashboardAdapter(DashboardManager.getInstance().getCountries(), R.layout.dashboard_row, this);
    mRecyclerView.setAdapter(mAdapter);

并且是dashboard_row.xml

请帮帮我....

Answer 1

从你发布的内容来看，你的 View onClick() 事件似乎被 TextView 消耗了

请删除:

 android:focusable="true"
 android:clickable="true"

标签来自 countryname TextView

同时将 getPosition() 更改为 getAdapterPosition()，因为 getPosition() 已弃用
