Setcontentview And Listeners

I'm changing my ContentView of the Activity at some point. (to View2). After changing it back to View1, the listeners are not more working. I already tried putting the Listener in

Solution 1:

Thank you all, for your reply. You made me realize, the onClickListeners are getting lost when I remove or replace (using setContentView()) the main view. I ended up this way now:

onCreate:

setContentView(R.layout.parse);
LinearLayoutcontainer= (LinearLayout) findViewById(R.id.container);
container.addView(getLayoutInflater().inflate(R.layout.dialog, null));
container.addView(getLayoutInflater().inflate(R.layout.progress, null));

onStartDoingSomething:

findViewById(R.id.dialog).setVisibility(View.INVISIBLE);
findViewById(R.id.progress).setVisibility(View.VISIBLE);

onEndDoingSomehting:

findViewById(R.id.dialog).setVisibility(View.VISIBLE);
findViewById(R.id.progress).setVisibility(View.INVISIBLE);

I might change View.INVISIBLE to View.GONE, like nmr said, but since I have never used View.GONE, I have to check the Android doku first ;)

Solution 2:

Assuming you use 'findViewById' to initialize 'button', you would need to do that every time that you do setContentView(R.layout.view1);

Solution 3:

You can only have one UI for each Activity, you should create another activity and in its onCreate method set the content view

Steps:

1. Create Activity

2. Use the following code to set the content View:

   public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.view2);

   }

3. Define the Activity in the applications manifest as such :

4. Create an intent in the first Activity:

   public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.view1);

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

   button.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { intent(); } }); }

   void intent(){

   Intent intent = new Intent();intent.setClass(Activity1.this, Activity2.class); startActivity(intent);

   }

And there you go c:
