Android:带有 CustomAdapter 的 CustomListView,Call Button 不工作
Android: CustomListView with CustomAdapter, Call Button is not working
在我的应用程序中,我有 3 次浏览
- 想象视图
- TextView
- 按钮
ImagView 相应地显示图像,TextView 和Button 相应地显示名称和编号。但问题是当我点击按钮时,它不会呼叫显示在按钮上的号码。尽管它确实会打开 android 来电应用程序。
电话号码在 string.xml 文件中。
这里我提供我所有的文件。请帮助我

您忘记在 MainActivity 中初始化电话字符串,执行与 movie_poster_resource 相同的操作,之后它应该可以工作,并且不要忘记添加权限
<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>
最后您可以使用
更新按钮点击代码
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:"+dataProvider.getTelePhone()));
startActivity(callIntent);
并以此
更新您的 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;
