Android - How do I set View.GONE outside the UI thread?
I want to make a view disappear (to be gone) when the user pushes a button.
I can make it inside the onCreate() method (main UI thread) by doing:
fi开发者_Python百科ndViewById(R.id.llLoadingGallery).setVisibility(View.GONE);
However, I want to be able to do the same thing inside another thread (out of the main UI thread). I tried to put the above live in my thread and it didn't work.
Thank you in advance!
## EDIT ####
To make myself more clear, I want to do something like this:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.teste_aba_3);
botao_tab_musica.setOnClickListener( new View.OnClickListener() {
@Override
public void onClick(View v) {
...
findViewById(R.id.llLoadingGallery).setVisibility(View.GONE);
}
});
}
However, that DOESN'T work! How can I fix this?
theres a neat method called runOnUiThread
runOnUiThread(new Runnable() {
@Override
public void run() {
findViewById(R.id.llLoadingGallery).setVisibility(View.GONE);
}
});
edit: with your code
botao_tab_musica.setOnClickListener( new View.OnClickListener() {
@Override
public void onClick(View v) {
runOnUiThread(new Runnable() {
@Override
public void run() {
findViewById(R.id.llLoadingGallery).setVisibility(View.GONE);
}
});
}
});
I'd suggest either using View.post(Runnable), View.postDelayed(Runnable, long), a Handler, or an AsyncTask to do this for you.
There are some good examples on how to post to the UI thread in these scenarios:
http://developer.android.com/resources/articles/painless-threading.html
I think one possibility is to pass a reference to your activity to that other thread so that your thread can access the findViewById method.
try this
findViewById(R.id.llLoadingGallery).post(new Runnable()
{
@Override
public void run()
{
findViewById(R.id.llLoadingGallery).setVisibility(View.GONE);
}
});
or create AsyncTask
