在app中我有一个Listactivity,它有一个带TextView和Button的适配器(标记为delete).现在我想删除相应的Button点击项目.请检查代码并建议???? `
public class MySimpleArrayAdapter extends ArrayAdapter<String> implements OnClickListener {
private final Activity context;
private final String[] names;
private Button deleteButton= null;
public MySimpleArrayAdapter(Activity context, String[] names) {
super (context, R.layout.imagelistlayout, names);
this.context = context;
this.names = names;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View rowView = inflater.inflate(R.layout.imagelistlayout, null, true);
deleteButton= (Button)rowView.findViewById(R.id.delete_bn);
deleteButton.setTag(position);
TextView textView = (TextView) rowView.findViewById(R.id.label);
textView.setText(names[position]);
deleteButton.setOnClickListener(this);
return rowView;
}
@Override
public void onClick(View convertView) {
System.out.println(deleteButton.getTag());
} …我正在开发一个应用程序,其中要求是在短信中发送链接.我正在使用MFMessageComposeViewControlleriPhone并尝试HTML字符串,但它不起作用.我正在使用代码:
-(IBAction)sendToSMS:(id)sender
{
MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
// NSArray *arr=[[NSArray alloc] initWithObjects:phoneNumber,nil];
// [controller setRecipients:[arr objectAtIndex:0]];
NSLog(@"received:- %@",controller.recipients);
controller.messageComposeDelegate = self;
controller.body =@"<html><body><font color=#FFFFFF>Hello,<br><a href=\"http://www.yahoo.com\">click</a>---here to go to Yahoo!</font></body></html>";
if([MFMessageComposeViewController canSendText])
{
[self presentModalViewController:controller animated:YES];
}
}
我想知道如何从给定的URL下载图像并将其显示在ImageView中.是否有permissions必要在manifest.xml文件中提及？
