私のアプリでは、私のJSONレスポンス内にブール変数があります。JSONのブール値を読み取る

私は私のモデルクラス内に作成セッターメソッドを使用してそれを読みます。ここまでは順調ですね。 今私は自分のカスタムアダプタに行き、そのjson変数が真（teamLead）であれば、対応するすべてのチームリーダーのテキストの色を変更します。
これは私のアダプタコードです。
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.RowHolderClass> {
private List<Model> modelList;
private Context mContext;
private int focused;
private ImageLoader mImageLoader;
public MyAdapter(Activity activity,List<Model> modelList) {
this.modelList = modelList;
this.mContext = activity;
}
@Override
public RowHolderClass onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.adapter_row,null);
final RowHolderClass holder = new RowHolderClass(v);
return holder;
}
@Override
public void onBindViewHolder(RowHolderClass holder, int position) {
final Model listItems = modelList.get(position);
holder.itemView.setSelected(focused==position);
holder.getLayoutPosition();
mImageLoader = AppController.getInstance().getImageLoader();
holder.imageView.setImageUrl(listItems.getProfileImageURL(),mImageLoader);
holder.fName.setText(Html.fromHtml(listItems.getFirstName()));
holder.lName.setText(Html.fromHtml(listItems.getLastName()));
holder.jobRole.setText(Html.fromHtml(listItems.getRole()));
holder.teamLeader.booleanValue();
//holder.fName.setTextColor(mContext.getResources().getColor(R.color.textColors));
holder.relativeLayout.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String first_name = listItems.getFirstName();
String last_name = listItems.getLastName();
String job_role = listItems.getRole();
String image_url = listItems.getProfileImageURL();
String id= String.valueOf(listItems.getId());
Intent i = new Intent(mContext, NewActivity.class);
i.putExtra("firstName",first_name);
i.putExtra("lastName",last_name);
i.putExtra("jobRole",job_role);
i.putExtra("imageUrl",image_url);
i.putExtra("memberId",id);
mContext.startActivity(i);
}
});
}
@Override
public int getItemCount() {
return (null != modelList?modelList.size() :0);
}
//ViewHolder algorithm used to read the data of the row fast.
class RowHolderClass extends RecyclerView.ViewHolder {
protected NetworkImageView imageView;
protected TextView fName, lName, jobRole;
protected RelativeLayout relativeLayout;
protected Boolean teamLeader;
public RowHolderClass(View itemView) {
super(itemView);
this.relativeLayout = (RelativeLayout) itemView.findViewById(R.id.recLayout);
this.imageView = (NetworkImageView) itemView.findViewById(R.id.imageView);
this.fName = (TextView) itemView.findViewById(R.id.firstName);
this.lName = (TextView) itemView.findViewById(R.id.lastName);
this.jobRole = (TextView) itemView.findViewById(R.id.roleView);
}
}
}
ご覧のとおり、私が望むすべての値が得られ、表示されます。しかし、私はこの
if(modelList.getTeamLead())
{
// Change color
}
else
{
// Do not change
}
は、API呼び出しのあなたの他の部分でこれを追加してみ
if(teamLeader is true){
//then change the text colours of the corresponding team leaders.
}
おかげで、
テオ
答えをありがとう。しかし、奇妙なことが起こります。私が最初にアプリを起動すると、チームのメンバーだけがハイライトされています。しかし、私がrecyclerviewをスクロールすると、一部の非鉛のメンバーも強調表示されます。これは私が色を変える方法です。 if（listItems.getTeamLead（））{ holder.fName.setTextColor（mContext.getResources（）。getColor（R.color.textColors））; holder.lName.setTextColor（mContext.getResources（）。getColor（R.color.textColors））; holder.jobRole.setTextColor（mContext.getResources（）。getColor（R.color.textColors））; } – Theo
そこに何か問題がありますが、私はそれを見ません。 – Theo
@テオ：テキストの色をデフォルトに変更するelse条件を記述する必要がありました。今あなたの問題は修正されると確信しています。 – Jeevanandhan
