Question

I have this neat app…

At onCreate, it draws the “startscreen.xml” accordingly to :

        super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
    setContentView(R.layout.startscreen);
    getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,
            R.layout.window_title);

And in my app, i have “configChanges=”orientation” ” in the manifest.
And i have,

    @Override
public void onConfigurationChanged(Configuration newConfig) {
  super.onConfigurationChanged(newConfig);
  setContentView(R.layout.startscreen);

}

startscreen.xml is both a landscape and portrait-layout, both are separated.

So to the problem, the app loads fine, buttons work. I switch orientation, the button stops responding…

They are both using RelativeLayout…

Any clues, anyone? :S

EDIT:

Tried this now thanks to your comments, but no result :S

    @Override
public void onConfigurationChanged(Configuration newConfig) {
  super.onConfigurationChanged(newConfig);
  setContentView(R.layout.startscreen);

    add_note.setOnClickListener(new View.OnClickListener() {
        public void onClick(final View v) {
            createNote();
        }

    });
}

Do you mean that onclickListener or these :

add_note = (Button) findViewById(R.id.addnote);

?? :S

Answer 1

If you are adding click listeners in onCreate to your buttons, you need to add listeners to the new button objects created in onConfigurationChanged.

You might consider using the android:onClick attribute in your XML files instead of setting click listeners in code. That’s a nice way of avoiding this problem.

To use android:onClick from XML, do something like this:

<Button
    android:id="@+id/addnote"
    android:onClick="addNoteMethod"
    ....
    />

Then in your activity, define the method:

public void addNoteMethod(View view) {
    createNote();
}

The name of the android:onClick method is totally arbitrary; it just has to match a method in your activity with the proper signature (void <method_name>(View)). The method will be called when there’s a click in exactly the same manner that the onClick method would be called for an OnClickListener.

When using android:onClick, you do not need to call setOnClickListener (or even retrieve a reference to the button in onCreate, unless you need it for something else).
