在 Android 中使用适配器中的对话框时显示 FC 错误

Question

我想在 Adapter 中使用 DialogBox，当启动应用程序并单击我的意思显示 FC 错误的区域时。

我的适配器代码：

public class newSMS_card_adapter extends
        RecyclerView.Adapter<newSMS_card_adapter.ViewHolder> {
    private static String[] mDataset;
    static public Context context;

    public newSMS_card_adapter(String[] myDataset) {
        mDataset = myDataset;

    }

    @Override
    public newSMS_card_adapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemLayoutView = LayoutInflater.from(parent.getContext()).inflate(
                R.layout.newsms_card_layout, null);


        ViewHolder viewHolder = new ViewHolder(itemLayoutView);
        return viewHolder;
    }

    @Override
    public void onBindViewHolder(ViewHolder viewHolder, int position) {

        // use and set objects

        viewHolder.newSMS_sms.setText(mDataset[position].toString());
        viewHolder.versionName=mDataset[position];

    }

    @Override
    public int getItemCount() {
        return mDataset.length;
    }

    public static class ViewHolder extends RecyclerView.ViewHolder {

        public TextView newSMS_sms, newSMS_count, newSMS_username, newSMS_hour, newSMS_date, newSMS_category;
        public String versionName;

        public ViewHolder(View itemLayoutView) {
            super(itemLayoutView);

            newSMS_sms = (TextView) itemLayoutView.findViewById(R.id.sms_newsms_text);
            newSMS_count = (TextView) itemLayoutView.findViewById(R.id.newSMS_count_text);
            newSMS_username = (TextView) itemLayoutView.findViewById(R.id.newSMS_username_text);
            newSMS_hour = (TextView) itemLayoutView.findViewById(R.id.newSMS_hour_text);
            newSMS_date = (TextView) itemLayoutView.findViewById(R.id.newSMS_Date_text);
            newSMS_category = (TextView) itemLayoutView.findViewById(R.id.newSMS_category_text);

            newSMS_sms.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {

                    final Dialog dialog = new Dialog(context);
                    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
                    dialog.setContentView(R.layout.show_sms__page);


                    //ImageView closeDialog_image = (ImageView) dialog.findViewById(R.id.addSMS_close_image);
                }
            });
        }
    }
}

Answer 1

试试这个

YourActivity activity;
public newSMS_card_adapter(....., YourActivity activity) {

    this.activity = activity;

}

现在

final Dialog dialog = new Dialog(activity);

最后，像这样调用适配器的构造函数...

newSMS_card_adapteradapter = new newSMS_card_adapter(...... , YourActivity.this);
