Question

在我的应用中，我有3个观看

ImagiveView
的TextView
按钮

ImagView相应地显示图像，TextView和Button显示相应的名称和编号。但问题是，当我点击按钮时，它不会调用按钮上显示的数字。虽然它确实打开了android调用者应用程序。

电话号码在string.xml文件中。

这里我提供了我的所有文件。请帮帮我

的strings.xml

<string-array name="names">
    <item>Abdul Malik</item>
    <item>Adeel ur Rehman</item>

Answer 1

您忘记在MainActivity中初始化电话字符串，执行相同的操作，因为它应该可以正常工作，并且不要忘记添加权限

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

最后你可以用

更新按钮点击代码

Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("tel:"+dataProvider.getTelePhone()));
    startActivity(callIntent);

并使用此

更新AdapterClass

public class MoviesAdapter  extends ArrayAdapter {

List list = new ArrayList();
public MoviesAdapter(Context context, int resource) {
    super(context, resource);

}

static class DataHandler {
    ImageView Poster;
    TextView title;
    Button telePhone;
}

@Override
public void add(Object object) {
    super.add(object);
    list.add(object);
}

@Override
public int getCount() {
    return this.list.size();
}

@Override
public Object getItem(int position) {
    return this.list.get(position);
}

@Override
public View getView(int position, View convertView, final ViewGroup parent) {
    View row;
    row = convertView;
    final MovieDataProvider dataProvider = (MovieDataProvider) this.getItem(position);;

    DataHandler handler;
    if (convertView == null) {

        LayoutInflater inflater = (LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        row = inflater.inflate(R.layout.row_layout, parent, false);
        handler = new DataHandler();
        handler.Poster = (ImageView) row.findViewById(R.id.movie_poster);
        handler.title = (TextView) row.findViewById(R.id.movie_title);
        handler.telePhone = (Button) row.findViewById(R.id.btn_call);
    } else {
        handler = (DataHandler) row.getTag();
    }

   handler.Poster.setImageResource(dataProvider.getMovie_poster_resource());
    handler.title.setText(dataProvider.getMovie_title());
    handler.telePhone.setText(dataProvider.getTelePhone());
    handler.telePhone.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            Intent intent = new Intent(Intent.ACTION_DIAL);
            intent.setData(Uri.parse("tel:" + dataProvider.getTelePhone()));
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            getContext().startActivity(intent);
        }
    });
    row.setTag(handler);
    return row;
}
}

Android：带CustomAdapter的CustomListView，调用按钮不起作用
