有人可以帮我设一个进度条，看起来与此类似; Example of Progress Bar。
这是我的代码;
public class exampleAlert extends DialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inf = getActivity().getLayoutInflater();
final View theDIalog = inf.inflate(R.layout.example_xml, null);
builder.setView(theDIalog);
builder.setCancelable(true);
final AlertDialog dialogscreen = builder.create();
theDIalog.findViewById(R.id.Ok).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final ProgressDialog dialog = new ProgressDialog(getActivity());
dialog.setTitle("Loading...");
dialog.setMessage("Please wait.");
dialog.setIndeterminate(true);
dialog.setCancelable(false);
dialog.show();
long delayInMillis = 2500;
Timer timer = new Timer();
timer.schedule(new TimerTask() {
@Override
public void run() {
dialog.dismiss();
}
}, delayInMillis);
AlertDialog.Builder builder1 = new AlertDialog.Builder(context);
builder1.setMessage("Write your message here.");
builder1.setCancelable(true);
builder1.setPositiveButton("Ok",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//put your code that needed to be executed when okay is clicked
dialogscreen.dismiss();
}
});
AlertDialog alert11 = builder1.create();
alert11.show();
}
});
return dialogscreen;
}
}
正如您所看到的，当单击“确定”按钮时，我将引入一个警告对话框。我想在此对话框出现在屏幕上之前带上进度条。
所以请有人帮我这样做。
