I want to redirect user to particular URL while clicking on Button in Android App. You can start a 'view' activity, which would be the browser given a URL: public class HelloWorld extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Assuming you are using xml layout Button button = (Button)findViewById(R.id.Button01); button.setOnClickListener(new OnClickListener() { public void onClick(View arg0) { Intent viewIntent = new Intent("android.intent.action.VIEW", Uri.parse("http://www.stackoverflow.com/")); startActivity(viewIntent);

问题 One of my layouts inside of my ViewPager has a button. "R.layout.add_site". I would like the option of hitting the button and it scroll to the specific page for me. I already have the option to swipe to the specific page, but I would like to have both. Now I'm sure there's a way to do that, but for some reason, I cannot figure it out.

Android layout as button with selectable functionality

有些话、适合烂在心里 提交于 2019-12-03 10:45:38
I'm trying to create a button-like component, with a left-aligned ImageView and then 2 TextViews to the right of the ImageView, stacked one above the other and formatted differently, like the following example:. __________________________ | | | |-----| Bold Main Text | | |Image| | | |-----| Small Sub Text | |__________________________| I also want the ImageView to change depending on the click state of the outer container, much like a standard button would do with a selectable resource associated with it. So that when I click anywhere in the outer box the image selectable state is changed. I

change button text color when pressed

问题 I have made my button transparent so I would like to have the button text color change when the button is pressed. Is it possible to do this using just xml files? 回答1: See the section called State List in this bit of documentation...Drawable Resources. You can define two different Button xml files one for the transparent 'default' state and another with the button as Red for your 'pressed' state. You then define a selector which switches the drawable resources in the different states. EDIT:

Removing the shadow on an android button

I have searched and tryed all found solutions to this. I need to remove the shadow from a button in android. Most of the solutions i found involve using an imagebutton and setting it's background. I tryed that and it works but my button has text so imagebutton is not an option. Unless there is a way to write to an imagebutton? My second solution was: android:fadingEdgeLength="0dp" But nothing seemed to change. Third: android:shadowColor="@color/application_transparent" /> Nothing changed here either. I also tryed creating a custom shape with stroke 0 and setting the buttons background to it

setting android button invisible but still having an onClick Listener attached

自古美人都是妖i 提交于 2019-12-03 03:16:00
So currently I'm putting an Easter egg inside my app and I want the Button to be invisible, but when clicked(Rick roll). So far I can make it work when I say: Button.setVisibility(view.VISIBLE); Button.setBackgroundColor(Color.TRANSPARENT); and then my onClickListener . The only problem with this is that I have to have text on the Button for it to be clickable. When I take the text out and make it completely invisible then the onClickListener is never called for some reason? Here is my OnClickListener wonderWhatThisDoes.setOnClickListener(new Button.OnClickListener() { @Override public void

Android: Goto HTTP Url on Button Click

I want to go to a web page on the click of a button in my Android app. So say, I have a button called "Google", when the user clicks on that button I want google.com to open up on the screen. How is this achieved? Also, is there a way I can gain control back to my app once the user is finished with Google? In your activity do something like this. public void openWebURL( String inURL ) { Intent browse = new Intent( Intent.ACTION_VIEW , Uri.parse( inURL ) ); startActivity( browse ); } By default, quitting the browser should return to your activity. However, there may be situations where it will
