Launch a custom dialog when clicked on notification

问题

I want to launch an custom dialog when user clicks on the notification in the notification bar.

I have already created the notification and the custom dialog class. But i do not know how to launch when user clicks it.

All tutorials i searched launch a Activity and not a dialog. So, can anyone help me with this regard.

Thank you.

This is my Custom Dialog code

public class custom_dialog extends Dialog {
    Context m_context;
    LayoutInflater mInflater = null;

    public custom_dialog (Context context, int theme) {
        super(context,R.style.Theme_Dialog);
        // TODO Auto-generated constructor stub
        this.m_context = context;
        Toast.makeText(getBaseContext(),"onCreate", Toast.LENGTH_SHORT).show();
        mInflater=LayoutInflater.from(m_context);
              }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
}

you can try with this code

Context context = getApplicationContext();
CharSequence contentTitle = "Title";
CharSequence contentText = "content";
Intent notifyIntent = new Intent(android.content.Intent.ACTION_VIEW,Uri.parse("http://www.android.com"));

PendingIntent intent = 
                PendingIntent.getActivity(SimpleNotification.this, 0, 
                notifyIntent, android.content.Intent.FLAG_ACTIVITY_NEW_TASK);

notifyDetails.setLatestEventInfo(context, contentTitle, contentText, intent);
mNotificationManager.notify(SIMPLE_NOTFICATION_ID, notifyDetails);

just make the pendingintent open up one of your activities and have your activity be complete transparent and just open a dialog.

Well any click is like a click on an element . I launch my custom dialog on click of a button. Here's how i do it :

main.xml :

<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>

custom.xml :

<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>

Now for the java to bind them :

MainActivity.java :

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("Custom 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();
          }
        });
    }
}

You can probably leverage this for your purpose ...
