display textview in alert dialog

Question

In my code, I have an AlertDialog and a TextView. I'd like display this TextViewin my AlertDialog but I don't know how to do it. I don't know how to add the View in a AlertDialog.

I could show my code but I don't think it would be usefull.

Thank's

EDIT:

Thank's for all your answers. I just did a test and it works perfectly.

Here is my working code:

package com.example.testalertdialog;

import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;
import android.widget.LinearLayout;
import android.widget.TextView;

public class MainActivity extends Activity {

    LinearLayout layout;
    AlertDialog ad;
    TextView tv1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        layout = new LinearLayout(this);
        ad = new AlertDialog.Builder(this).create();
        tv1 = new TextView(this);
        setContentView(layout);
        tv1.setText("Test");
        ad.setView(tv1);
        ad.show();

    }
}

Edit2: But why doesn't this code work ?

package com.example.testalertdialog;

import android.annotation.SuppressLint;
import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.TextView;

@SuppressLint("HandlerLeak")
public class MainActivity extends Activity implements OnClickListener{

    LinearLayout layout;
    AlertDialog ad;
    TextView tv1;
    Button b1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        layout = new LinearLayout(this);
        tv1 = new TextView(this);
        b1 = new Button(this);
        b1.setOnClickListener(this);
        layout.addView(b1);
        ad = new AlertDialog.Builder(this).create();
        setContentView(layout);
        tv1.setText("Test");
}

    @Override
    public void onClick(View v) {
        if (v == b1) {

        ad.setMessage("Chargement");
        ad.show();
        ad.setView(tv1);
    }
}

}

Solution 1

AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Title");
alert.setMessage("Message");
// Create TextView
final TextView input = new TextView (this);
alert.setView(input);

alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
     input.setText("hi");
    // Do something with value!
  }
});

  alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
  public void onClick(DialogInterface dialog, int whichButton) {
      // Canceled.
  }
});
alert.show();

Solution 2

Here in the part custom layout - you can create a custom layout for your alertDialog, not only in textview, but anything.

Link to simplify: here is my code from my game

//create builder
AlertDialog.Builder builder = new AlertDialog.Builder(GWGPlay.this);
//inflate layout from xml. you must create an xml layout file in res/layout first
LayoutInflater inflater = GWGPlay.this.getLayoutInflater();
View layout = inflater.inflate(R.layout.guesskeyword    /*my layout here*/, null);
builder.setView(layout);
//set 2 main buttons
builder.setPositiveButton("Answer", new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    endGame(true);
                }
            });

builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {

                }
            });

            builder.show();

[Yoda]

There is no TextView visible in this alert : (.

[Mystery]

@Yoda for EditText use final EditText input = new EditText (this);
