public class CustomDialogBoxActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button button = (Button)findViewById(R.id.Button01main);

        button.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                final Dialog myDialog = new Dialog(CustomDialogBoxActivity.this);
                myDialog.setContentView(R.layout.dialog_sms_layout);
                myDialog.setTitle("Select any one");


                Button ok = (Button)myDialog.findViewById(R.id.buttonOK);
                final RadioGroup radioGrp = (RadioGroup)myDialog.findViewById(R.id.radioGroupSmsDialog);

                final CheckBox mob1 = (CheckBox)myDialog.findViewById(R.id.checkBoxMob1);
                final CheckBox mob2 = (CheckBox)myDialog.findViewById(R.id.checkBoxMob2);
                mob1.setText("9029691986");
                mob2.setText("99263911766");

                ok.setOnClickListener(this);

                ok.setOnClickListener(new OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        // TODO Auto-generated method stub
                        if(mob1.isChecked() && mob2.isChecked()) {
                            if(radioGrp.getCheckedRadioButtonId() == R.id.radioSms) {
                                String[] phoneArray = {mob1.getText().toString(),mob2.getText().toString()};

                                Log.v("MOB1",mob1.getText().toString());
                                Log.v("MOB2",mob2.getText().toString());
                                Log.v("Mobile No", ""+phoneArray.toString());
                                sendSms("SMS Message",phoneArray);

                            }else if(radioGrp.getCheckedRadioButtonId() == R.id.radioBusinessCard) {
                                String[] phoneArray = {mob1.getText().toString(),mob2.getText().toString()};

                                Log.v("MOB1",mob1.getText().toString());

                                sendSms("SMS Business Card",phoneArray);
                            }
                        }else if(mob1.isChecked() && !mob2.isChecked()) {
                            if(radioGrp.getCheckedRadioButtonId() == R.id.radioSms) {
                                String[] phoneArray = {mob1.getText().toString()};

                                Log.v("MOB1",mob1.getText().toString());                                
                                Log.v("Mobile No", ""+phoneArray.toString());
                                sendSms("SMS Message",phoneArray);

                            }else if(radioGrp.getCheckedRadioButtonId() == R.id.radioBusinessCard) {
                                String[] phoneArray = {mob1.getText().toString()};

                                Log.v("MOB1",mob1.getText().toString());                                
                                Log.v("Mobile No", ""+phoneArray.toString());
                                sendSms("SMS Business Card",phoneArray);
                            }

                        }else if(!mob1.isChecked() && mob2.isChecked()) {
                            if(radioGrp.getCheckedRadioButtonId() == R.id.radioSms) {
                                String[] phoneArray = {mob2.getText().toString()};

                                Log.v("MOB2",mob2.getText().toString());
                                Log.v("Mobile No", ""+phoneArray.toString());
                                sendSms("SMS Message",phoneArray);

                            }else if(radioGrp.getCheckedRadioButtonId() == R.id.radioBusinessCard) {
                                String[] phoneArray = {mob2.getText().toString()};

                                Log.v("MOB2",mob2.getText().toString());
                                Log.v("Mobile No", ""+phoneArray.toString());
                                sendSms("SMS Business Card",phoneArray);
                            }

                        }else if(!mob1.isChecked() && !mob2.isChecked()) {
                            Toast.makeText(getApplicationContext(), "Select atleast one number", Toast.LENGTH_SHORT).show();
                        }                       
                    }
                });
                myDialog.show();
            }

        });
    }

    public void sendSms(String message,String[] phoneNumber) {

        Intent smsIntent = new Intent(Intent.ACTION_VIEW);
        smsIntent.setData(Uri.parse("sms:"));
        smsIntent.putExtra("sms_body", message);
        smsIntent.putExtra("address", phoneNumber);
        startActivity(smsIntent);       
    }
}

This is the output that i’m getting on button click

This is my 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" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="This is my main activity, from here, I want to display a dialog, 
                        after the user clicked the button below this text." />

    <Button
        android:id="@+id/Button01main"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Show Dialog" />

</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"

Answer 1

I’m not sure if this will work for your situation, but if you want to set it to full width or something similar, you need to get the current Window for the activity and set it’s layout params like so:

myDialog.show();
Window window = myDialog.getWindow();
window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);

Edit

FILL_PARENT has been deprecated, use instead

window.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
