android - একটি ডায়ালগে একটি সম্পাদনা বাক্স কিভাবে করবেন




dialog android-edittext (6)

অ্যাক্টিভিটি কনটেক্সট ব্যবহার করুন

এই প্রতিস্থাপন করুন

  final EditText input = new EditText(this);

দ্বারা

  final EditText input = new EditText(MainActivity.this);  
  LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
                        LinearLayout.LayoutParams.MATCH_PARENT,
                        LinearLayout.LayoutParams.MATCH_PARENT);
  input.setLayoutParams(lp);
  alertDialog.setView(input); // uncomment this line

আমি একটি পাসওয়ার্ড প্রবেশের জন্য একটি ডায়লগ বাক্সে একটি সম্পাদনা বাক্স তৈরি করার চেষ্টা করছি। এবং যখন আমি করছি আমি করতে পারবেন না। আমি এটি একটি শিক্ষানবিশ। এই আমাকে সাহায্য করুন।

public class MainActivity extends Activity {

আমি হিসাবে পেতে চান

 AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this);
 alertDialog.setTitle("PASSWORD");
 alertDialog.setMessage("Enter Password");

 final EditText input = new EditText(MainActivity.this);
 LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
     LinearLayout.LayoutParams.MATCH_PARENT,
     LinearLayout.LayoutParams.MATCH_PARENT);
 input.setLayoutParams(lp);
 alertDialog.setView(input);
 alertDialog.setIcon(R.drawable.key);

 alertDialog.setPositiveButton("YES",
     new DialogInterface.OnClickListener() {
         public void onClick(DialogInterface dialog, int which) {
             password = input.getText().toString();
             if (password.compareTo("") == 0) {
                 if (pass.equals(password)) {
                     Toast.makeText(getApplicationContext(),
                         "Password Matched", Toast.LENGTH_SHORT).show();

 });

আপনি একটি XML ফাইল তৈরি করে কাস্টম সতর্কতা সংলাপ তৈরি করতে পারেন।

কোটলিনের জন্য এনকো লাইব্রেরির সাথে লড়াই বন্ধ করতে পারে? ...

alert( "Title", "Message") {
            var input: EditText? = null
            customView {
                input = editText() {
                    hint = "Write your message in here"
                }
            }
            yesButton { toast("field text: ${input?.text}") }
            negativeButton("Nope") { } // Empty dismisses the alert
        }.show()

নীচের কোডটি চেষ্টা করুন:

alert.setTitle(R.string.WtsOnYourMind);

 final EditText input = new EditText(context);
 input.setHeight(100);
 input.setWidth(340);
 input.setGravity(Gravity.LEFT);

 input.setImeOptions(EditorInfo.IME_ACTION_DONE);
 alert.setView(input);

সব সহজ হবে।

  • ডায়ালগ জন্য XML লেআউট ফাইল তৈরি করুন। আপনি EditText, ListView, স্পিনার ইত্যাদি মত চান যাই হোক না কেন দেখুন যোগ করুন।

    এই দৃশ্যে Inflate এবং AlertDialog সেট করুন

প্রথমে লেআউট ফাইল দিয়ে শুরু করা যাক।

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"

    android:orientation="vertical">


    <EditText
        android:id="@+id/etComments"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="top"
        android:hint="Enter comments(Optional)"
        android:inputType="textMultiLine"
        android:lines="8"
        android:maxLines="3"
        android:minLines="6"
        android:scrollbars="vertical" />

</LinearLayout>
final View view = layoutInflater.inflate(R.layout.xml_file_created_above, null);
AlertDialog alertDialog = new AlertDialog.Builder(ct).create();
alertDialog.setTitle("Your Title Here");
alertDialog.setIcon("Icon id here");
alertDialog.setCancelable(false);
Constant.alertDialog.setMessage("Your Message Here");


final EditText etComments = (EditText) view.findViewById(R.id.etComments);

alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "OK", new OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {

    }
});


alertDialog.setButton(AlertDialog.BUTTON_NEGATIVE, "Cancel", new OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        alertDialog.dismiss()
    }
});


alertDialog.setView(view);
alertDialog.show();
