Cómo hacer un cuadro edittext en un diálogo


Estoy tratando de hacer un edittext cuadro en un cuadro de diálogo para introducir la contraseña. y cuando lo estoy haciendo no soy capaz de hacerlo. Soy un principiante en ella. Por favor, ayúdame con esto.

public class MainActivity extends Activity {

Button create, show, setting;
//String pass="admin";String password;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    create = (Button)findViewById(R.id.amcreate);
    setting = (Button)findViewById(R.id.amsetting);
    show = (Button)findViewById(R.id.amshow);
    //input = (EditText)findViewById(R.id.this);

    setting.setVisibility(View.INVISIBLE);

    create.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            Intent myIntent1 = new Intent(view.getContext(), Create.class);
            startActivityForResult(myIntent1, 0);
        }

    });

    show.setOnClickListener(new View.OnClickListener() {
        //@SuppressWarnings("deprecation")
        public void onClick(final View view) {

            // Creating alert Dialog with one Button
            AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this);

            //AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();

            // Setting Dialog Title
            alertDialog.setTitle("PASSWORD");

            // Setting Dialog Message
            alertDialog.setMessage("Enter Password");
            **final EditText input = new EditText(this);**
            //alertDialog.setView(input);

            // Setting Icon to Dialog
            alertDialog.setIcon(R.drawable.key);

            // Setting Positive "Yes" Button
            alertDialog.setPositiveButton("YES",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog,int which) {
                            // Write your code here to execute after dialog
                            Toast.makeText(getApplicationContext(),"Password Matched", Toast.LENGTH_SHORT).show();
                            Intent myIntent1 = new Intent(view.getContext(), Show.class);
                            startActivityForResult(myIntent1, 0);
                        }
                    });
            // Setting Negative "NO" Button
            alertDialog.setNegativeButton("NO",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            // Write your code here to execute after dialog
                            dialog.cancel();
                        }
                    });

            // closed

            // Showing Alert Message
            alertDialog.show();
        }

    });

Use el Contexto de actividad

Sustitúyase esto

  final EditText input = new EditText(this);

Por

  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

Sé que es demasiado tarde para responder a esta pregunta, pero para otros que están buscando algo similar a esto, aquí hay un código simple de una alertbox con un edittext

AlertDialog.Builder alert = new AlertDialog.Builder(this); 

O

new AlertDialog.Builder(mContext, R.style.MyCustomDialogTheme);

Si desea cambiar el tema del diálogo.

final EditText edittext = new EditText(ActivityContext);
alert.setMessage("Enter Your Message");
alert.setTitle("Enter Your Title");

alert.setView(edittext);

alert.setPositiveButton("Yes Option", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int whichButton) {
        //What ever you want to do with the value
        Editable YouEditTextValue = edittext.getText();
        //OR
        String YouEditTextValue = edittext.getText().toString();
    }
});

alert.setNegativeButton("No Option", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int whichButton) {
        // what ever you want to do with No option.
    }
});

alert.show();

Versión simplificada

final EditText taskEditText = new EditText(this);
AlertDialog dialog = new AlertDialog.Builder(this)
        .setTitle("Add a new task")
        .setMessage("What do you want to do next?")
        .setView(taskEditText)
        .setPositiveButton("Add", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                String task = String.valueOf(taskEditText.getText());
                SQLiteDatabase db = mHelper.getWritableDatabase();
                ContentValues values = new ContentValues();
                values.put(TaskContract.TaskEntry.COL_TASK_TITLE, task);
                db.insertWithOnConflict(TaskContract.TaskEntry.TABLE,
                        null,
                        values,
                        SQLiteDatabase.CONFLICT_REPLACE);
                db.close();
                updateUI();
            }
        })
        .setNegativeButton("Cancel", null)
        .create();
dialog.show();
return true;

Intente debajo del código:

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);

El más simple de todos sería.

  • Cree un archivo de diseño xml para el diálogo . Añadir cualquier vista que desee como EditText, ListView, Spinner, etc.

    Inflar esta vista y establecerla en AlertDialog

Comencemos con el archivo de diseño primero.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_horizontal"
    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();

También puede crear un diálogo de alerta personalizado creando un archivo xml.

Dialoglayout.xml

   <EditText
    android:id="@+id/dialog_txt_name"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_margin="10dp"
    android:hint="Name"
    android:singleLine="true" >

    <requestFocus />
  </EditText>
   <Button
        android:id="@+id/btn_login"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="60dp"
        android:background="@drawable/red"
        android:padding="5dp"
        android:textColor="#ffffff"
        android:text="Submit" />

    <Button
        android:id="@+id/btn_cancel"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_toRightOf="@+id/btn_login"
        android:background="@drawable/grey"
        android:padding="5dp"
        android:text="Cancel" />

El Código Java:

@Override//to popup alert dialog
public void onClick(View arg0) {
    // TODO Auto-generated method stub
    showDialog(DIALOG_LOGIN);
});


@Override
protected Dialog onCreateDialog(int id) {
    AlertDialog dialogDetails = null;

    switch (id) {
        case DIALOG_LOGIN:
            LayoutInflater inflater = LayoutInflater.from(this);
            View dialogview = inflater.inflate(R.layout.dialoglayout, null);
            AlertDialog.Builder dialogbuilder = new AlertDialog.Builder(this);
            dialogbuilder.setTitle("Title");
            dialogbuilder.setView(dialogview);
            dialogDetails = dialogbuilder.create();
            break;
    }
    return dialogDetails;
}

@Override
protected void onPrepareDialog(int id, Dialog dialog) {
    switch (id) {
        case DIALOG_LOGIN:
             final AlertDialog alertDialog = (AlertDialog) dialog;
             Button loginbutton = (Button) alertDialog
                .findViewById(R.id.btn_login);
             Button cancelbutton = (Button) alertDialog
                .findViewById(R.id.btn_cancel);
             userName = (EditText) alertDialog
                .findViewById(R.id.dialog_txt_name);
             loginbutton.setOnClickListener(new View.OnClickListener() {
                  @Override
                  public void onClick(View v) {
                      String name = userName.getText().toString();
                      Toast.makeText(Activity.this, name,Toast.LENGTH_SHORT).show();
             });
             cancelbutton.setOnClickListener(new View.OnClickListener() {
                      @Override
                      public void onClick(View v) {
                           alertDialog.dismiss();
                      }
             });
             break;
   }
}

Establecer el margen en los parámetros de diseño no funcionará en Alertdialog. debe establecer el relleno en el diseño principal y luego agregar edittext en ese diseño.

Este es mi código kotlin de trabajo...

val alert =  AlertDialog.Builder(context!!)

val edittext = EditText(context!!)
edittext.hint = "Enter Name"
edittext.maxLines = 1

val layout = FrameLayout(context!!)

//set padding in parent layout
layout.setPaddingRelative(45,15,45,0)

alert.setTitle(title)

layout.addView(edittext)

alert.setView(layout)

alert.setPositiveButton(getString(R.string.label_save), DialogInterface.OnClickListener {

    dialog, which ->
    run {

        val qName = edittext.text.toString()

        Utility.hideKeyboard(context!!, dialogView!!)

    }

})
alert.setNegativeButton(getString(R.string.label_cancel), DialogInterface.OnClickListener {

            dialog, which ->
            run {
                dismiss()
            }

})

alert.show()
