1 Android Layout Files

Two XML files, one for main screen, one for custom dialog.

File : res/layout/main.xml


<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
 
    <Button
        android:id="@+id/buttonShowCustomDialog"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Show Custom Dialog" />
         
</LinearLayout>

File : res/layout/custom.xml


<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >
 
    <ImageView
        android:id="@+id/image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="5dp" />

    <TextView
        android:id="@+id/text"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textColor="#FFF" 
        android:layout_toRightOf="@+id/image"/>/>
 
     <Button
        android:id="@+id/dialogButtonOK"
        android:layout_width="100px"
        android:layout_height="wrap_content"
        android:text=" Ok "
        android:layout_marginTop="5dp"
        android:layout_marginRight="5dp"
        android:layout_below="@+id/image"
        />
     
</RelativeLayout>

2. Activity

Read the comment and demo in next step, it should be self-explorary.

File : MainActivity.java


package com.mkyong.android;

import android.app.Activity;
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;

public class MainActivity extends Activity {

	final Context context = this;
	private Button button;

	public void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

		button = (Button) findViewById(R.id.buttonShowCustomDialog);

		// add button listener
		button.setOnClickListener(new OnClickListener() {

		  @Override
		  public void onClick(View arg0) {

			// custom dialog
			final Dialog dialog = new Dialog(context);
			dialog.setContentView(R.layout.custom);
			dialog.setTitle("Title...");

			// set the custom dialog components - text, image and button
			TextView text = (TextView) dialog.findViewById(R.id.text);
			text.setText("Android custom dialog example!");
			ImageView image = (ImageView) dialog.findViewById(R.id.image);
			image.setImageResource(R.drawable.ic_launcher);

			Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
			// if button is clicked, close the custom dialog
			dialogButton.setOnClickListener(new OnClickListener() {
				@Override
				public void onClick(View v) {
					dialog.dismiss();
				}
			});

			dialog.show();
		  }
		});
	}
}

  17. Why not take a look at my blog about how to create an Android app that displays an Image in an ImageView control of the main Activity at the full width of the screen.

    The app uses the following Android SDK objects:

    . Display
    . ImageView
    . LinearLayout
    . Bitmap
    . Activity
    . XML layout
    . LayoutParams

    Also:
    . layout_width
    . layout_height
    . orientation
    . id
    . vertical
    . match_parent

    XML attributes and values are covered.

  30. Why do You declare the private Button button; and not as

    Button button = (Button) findViewById(R.id.buttonShowCustomDialog);

    The truth is the app crashes but I don’t understand why.

  31. this was very useful to me but can some please let me know how to call a custom dialog from service i wrote the code inside onClick part in a different file passed the context from service and called the custom.xml file from the java file i wrote but its failing

    Reply

  32. Thanks, that’s helpful.

    One little change I needed to make to get it to compile was to change the line:
    dialogButton.setOnClickListener(new OnClickListener() {

    to
    dialogButton.setOnClickListener(new View.OnClickListener() {

  36. Hi mkYong, First of all congratulations for your demos, are so useful.

    I’m new on the android world and i have a problem, i’m trying to show a dialog when i choose a concrete option in my spinner, but when i do this, my application crashes and stops the program.

    The code is something like this:

    public void onItemSelected(final AdapterView parent, View view, int pos,long id) {

    String addSM = parent.getItemAtPosition(pos).toString();

    if (addSM == “A?adir”){

    // custom dialog
    final Dialog dialog = new Dialog(controlador.context);
    dialog.setContentView(R.layout.dialog_afegirsuper);
    dialog.setTitle(“Title…”);

    // set the custom dialog components – text, image and button
    TextView text = (TextView) dialog.findViewById(R.id.text);
    text.setText(“Android custom dialog example!”);

    Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
    // if button is clicked, close the custom dialog
    dialogButton.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
    dialog.dismiss();
    }
    });

    dialog.show();
    }
    }

    thanks a lot for any solution.

    1. When you compare strings, you must do it like this:
      if(addSM.equals(“Añadir”))
      The way you are doing it is wrong. Try this change and then make a reply if everything is going well.

      Regards

      Reply

      1. @Ricardo A.Hermosilla Carrillo
        Yes, you said right. Better way is using if(“Añadir”.equals(addSM)) this will
        prevent the case addSM is null too.

    2. I recommend you not to work with spanish-symbols and/or non-english-symbols, it can give some problems if not configured properly.
      “Anadir” rather “Añadir” 🙂
      //////
      Te recomiento no trabajar con símbolos en español y/o en otro idioma distinto del inglés, a veces puede traer algunos problemas si no es configurado apropiadamente.
      es mejor “Anadir” en vez de “Añadir”

  38. Very useful example. I tried to do a simpler example myself and initially I wrote it like this:

    public class MainActivity extends Activity {

    Context mContext = null;
    Dialog dialog = null;

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

    mContext = getApplicationContext();
    dialog = new Dialog(mContext);

    dialog.setContentView(R.layout.custom_dialog);

    dialog.setTitle(“Custom Dialog”);
    TextView text = (TextView) dialog.findViewById(R.id.text);
    text.setText(“Hello, this is a custom dialog!”);
    ImageView image = (ImageView) dialog.findViewById(R.id.image);
    image.setImageResource(R.drawable.ic_launcher);

    dialog.show();
    }

    }

    The result was that the application crashed right after launching. Then I compared it to your example and I saw that the assignment

    Context mContext = null;

    should be instead

    Context mContext = this;

    and also the assignment to mContext inside the method becomes no longer necessary. I would be very grateful if someone could explain why is this so. It seems reasonable, though I can’t grasp the full meaning.

    Thank you, mkyong!!

  39. To remove the dialog’s title,

    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

    before you set the layout (with dialog.setContentView(R.layout.education_details_layout);)

  42. Nice tutorial. I have a question. Question is what if I want to return some value to activity from this dialog. Here is my example.

    Activity layout file : activity_my_dialog.xml

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

    What ever details I am accepting from dialog box needs to be appended in the EditText component in main activity.

    Please help me. Thanks in advance.

    1. I got the answer myself. Answer is to add OnDismissListener() to dialog as below:

      MyDialogActivity.java

      package com.myclass.mydialog;

import android.os.Bundle;
import android.app.Activity;
import android.app.Dialog;
import android.content.DialogInterface;
import android.content.DialogInterface.OnDismissListener;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MyDialogActivity extends Activity implements OnClickListener {
	Button btn;
	EditText et;
	Mydialog d;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_my_dialog);
		btn = (Button) findViewById(R.id.btn);
		et = (EditText) findViewById(R.id.etd);
		d = new Mydialog(this);
		
		btn.setOnClickListener(this);
		d.setOnDismissListener(new OnDismissListener() {
			
			@Override
			public void onDismiss(DialogInterface dialog) {
				// TODO Auto-generated method stub
				String result = d.getResult();
				if(result.equals(""))
				{
					Toast.makeText(getBaseContext(), "Action cancelled", Toast.LENGTH_LONG).show();
				}
				else
				{
					et.append("\n"+result);
				}
			}
		});
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.activity_my_dialog, menu);
		return true;
	}

	@Override
	public void onClick(View v) {
		// TODO Auto-generated method stub
		if(v == btn)
		{
			d.show();
			
			
		}
	}

  51. Hi, mkYong
    The section
    dialogButton.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
    dialog.dismiss();
    }
    });
    crashed on my app.
    But not on your sample code.
    What could happened?
    Thanks

  57. Hi could you please tell me how can I add this into my existing application. I understand how to add the xml layout files, but not sure where to add the .java file. Is it under the src folder ? I tried adding your two xml files and the .java file to my app but when I launch the app nothing appears. not even an error message
