I am creating a layout through code and want to add a View to that layout. The view which is to be added is defined in the xml file. Is there any way to use an View from xml before calling setContentView method. Because we can not call findViewById before setContentView.

View 4 Replies View RelatedI see a strange problem when I try to set a TextView, instead of a layout file via setContentView.
Case 1: i.e. if I do the following, it works fine...
TextView tv = new TextView(this); tv.setText("Hello World"); setContentView(tv);
Everything is OK.
Case 2: But suppose I have a main.xml file with a TextView in it and I try the following:
=========== View tv = findViewById(R.id.textview); setContentView(tv); =========== I get a Force Close with the below error

View 2 Replies View RelatedSo I have my main activity. It starts out adding a custom SurfaceView called DrawView as the content view with
DrawView drawview = new DrawView(parameters);
this.setContentView(drawview);
now my layout.main.xml is a layout with a video view which I am using to play my cutscenes. I am able to switch to this view by calling a method I made which switches the content view by
this.setContentView(R.layout.main);
which works fine when I am calling this method within the Activity. Only problem is I need to call this method from within DrawView! The method I made to switch to my cutscene is public and I do pass the Activity (named Draw) as a parameter of DrawView.
So when I do call this method from within DrawView my game freezes and will subsequently crash! however it works when method is called locally?
I have 3 activities in my app: Activity1 -> Activity2 -> Activity3. Inside Activity3, if the user presses Back, I would like to return to Activity2. In Activity3's onPause event, I added a finish() statement. That's probably not even necessary, but I wanted to make sure this Activity gets cleaned up. This works fine.
However, while in Activity3, if the user presses Home or starts a new app (through notification bar or some other means), I want both Activity3 and Activity2 to finish. If the user returns to this app, he should resume with Activity1.
I have figured out how to do one or the other, but I can't figure out how to handle both cases, if it's even possible. Can I trap the "Back" button in Activity3 and send a message back to Activity2 telling it not to finish()? It seems like the Activities follow the same lifecycle flow (Pause, Stop) regardless of what you do to send them to the background. Just to answer the question of why I want this behavior, imagine that Activity1 is a login screen, Activity2 is a selection screen, and Activity3 is a content screen. If I press Back from the content page, I want to be able to make a new selection. If I exit via any other means (Home, notification bar), I want the user to be "logged out".
On the iPhone, when you hold down the top button and the button on the bottom it takes a snap shot of your screen, I love that feature. Does the droid have it?

View 1 Replies View RelatedI like being able to wake the phone to view the lock screen using the home button at the bottom of the phone, but is there any way to make it so that a second click of that button, or a click of one of the others down there, will make it sleep again? Having to press the power button up top is just an inconvenience.

View 1 Replies View Relateddoes anyone know if its possible or what app would be used to have the optical button work the same as the power button on the top of the phone. so if you push the button it would light the display up. or maybe its not even possible.
View 1 Replies View RelatedI tried searching for this but couldn't find a thread that discussed it. My power button appears as though its been jammed. I dropped my phone on its corner where the power button is but I don't think thats what the problem is. Anyhow, recently my power button responds but I have to really press it hard and it as though the button is jammed cause it doesn't depress as far.
My question is that is there a way to designate the camera button to become the power button? I know on some phones you can make different buttons do different things and I was curious if this was possible on the Droid.
i have a button setup to play a sound,but nothing plays until i release the button again. here's my code
Code:
bKick.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
sp.play(dance_kick, 1, 1, 1, 0, 1);
}
});
this morning when I wake up I realized that:
- home button is not working
- call button is not working unless you're into the contacts application (doesn't work from home page)
- Astrid application has lost all of the TODO tasks.
- It doesn't asks for the unlock graphical code!
It lost all of its battery yesterday night while surfing on the browser. My phone is an HTC MAgic Vodafone, using Android 1.6 Any ideas on how should i proceed? I soft reset the phone already.
This would fix my only complaint about the phone! It's quite annoying when I'm in a call and doing something else on the phone, and I lose the soft end call button and can't hang up.
View 1 Replies View RelatedOn pressing the back button, I'd like my application to go into the stopped state, rather than the destroyed state. In the Android docs it states: not all activities have the behavior that they are destroyed when BACK is pressed. When the user starts playing music in the Music application and then presses BACK, the application overrides the normal back behavior, preventing the player activity from being destroyed, and continues playing music, even though its activity is no longer visible
How do I replicate this functionality in my own application? I think there must be three possibilities.
1) Capture the back button press (as below) and then call whatever method(s) the home button calls...........
The above is the code I have written for filling borders of Button with black color.The same code I was using for 3 buttons by setting as background.Now, when I click button1, red color appears and goes when I releases. But I want Red color to be visible, until I press next button.Though I release Button1 after press, Red color should be visible. But Red color should only disappear when I press any other button.

I have this at the top of my application. When the application starts, the EditText is orange highlighted and has a cursor in it; when the EditText is tapped, the soft keyboard pops up. The user uses it to type into the EditText.
However, when they click the Button, my onClick method fires and does everything it's supposed to, however the soft keyboard stays on screen and the EditText is still highlighted with its cursor.
I also have, at the top of the Button onclick: findViewById(R.id.name).clearFocus();
In spite of this, the EditText does not seem to clear its focus. How do I make the button actually act as if it is submitting the form?
Also, I do not transition to a different Activity on the click of the Button. I suppose that is the typical case, and probably the reason why they don't bother hiding the keyboard. However I want to keep the search box and button at the top of the screen, so I just dynamically fill and add views to the screen when the Button is pressed. How can I achieve my desired behavior?
